Definitions

  • the invention relates to a connection arrangement for at least one flexible connection element, in particular a connection element for connecting two cars of a rail-bound means of transport, and a rail vehicle with such a connection arrangement.
  • connections for transporting work equipment e.g. B. a brake fluid, a coolant, compressed air or electrical connecting elements for conducting electrical energy.
  • Suitable connecting elements for this can be cables, lines or hoses. These are either routed below the connected wagons or below their wagon bodies, although a safety distance to the rail and to the underside of the wagons must be maintained, or above the wagons or wagon boxes on the roof, again keeping safety distances from moving parts or the overhead line ,
  • connection devices are on the elements of the means of transport to be connected arranged devices to which the connecting element is mechanically fixed or to which the connecting element is mechanically connected.
  • a bracket must also allow pivoting, nodding and swaying of the connected wagons. Furthermore, the connecting elements must not protrude from a predetermined space, which is bounded in particular downwards towards the track bed or wagon roof and laterally, so that the connecting elements cannot pose a hazard.
  • EP 2495151 A1 discloses a holding device for holding at least one flexible connecting element, wherein by means of the connecting element it is possible to connect two elements spaced apart from one another and pivotable relative to one another about an axis of rotation, in particular carriages of a rail-bound means of transport.
  • the holding device has at least three links, each link having two swivel joints.
  • the links are rotatably fastened to one another by means of the swivel joints in such a way that the links form a link chain, end links of the chain being rotatably fastened to a carrier device by means of one of their swivel joints.
  • At least one member is designed as a holding member, the holding member forming a holding device or having a holding device, the flexible connecting element being able to be fixedly connected to the holding member by means of the holding device.
  • this holding device two elements which can be pivoted relative to one another can be connected in such a way that a necessary sag of the connecting elements and thus also a required installation space for these connecting elements is reduced.
  • connection of connection elements in the area of vehicle joints still leads to the problem of the connection elements bending in the area of the ends of the connection elements when rail vehicle elements, such as, for example, carriages, are pivoted relative to one another about the axis of rotation of the joint.
  • This bending which in extreme cases can lead to kinking, affects the durability of the connecting elements.
  • large radii have been selected for the guidance of connecting elements and connecting elements have been designed to be long so that they have a large excess length when driving straight ahead, which serves to compensate for the change in distance between the first and the second connecting device when cornering.
  • This excess length leads however, to a large sag of the connecting elements, so that suspensions against excessive sag are necessary.
  • the object of the present invention is to provide a solution to this problem.
  • a solution should be specified as to how the connecting means are made as short as possible and thereby an excess length can be reduced.
  • connection arrangement according to claim 1.
  • a first connection device to which a flexible connecting element can be connected, is rotatably mounted on a first rail vehicle element, for example a carriage, car body or module
  • a second connection device to which the flexible connecting element can be connected, is rotatably mounted on a second rail vehicle element.
  • connection devices can counteract a rotary movement or swiveling of the rail vehicle elements about an axis of rotation of the joint and compensate in the extreme case, which does not always have to be the case. This is particularly the case if the connection devices are each rotatably mounted on a rail vehicle element. In this case, the connection devices can perform a counter-rotation movement to the rotation of the rail vehicle elements about an axis of rotation of the joint.
  • the course of a connecting element between rail vehicle elements depends on the angle of rotation between the rail vehicle elements, also referred to as the joint angle or Swivel angle, automatically optimized in that, as a result of a rotation of the rail vehicle elements relative to one another about the axis of rotation of the joint, the position of each connection device relative to the rail vehicle element on which it is movably mounted adjusts itself automatically and an optimized guidance of the connecting element is achieved.
  • Optimized guidance of the connecting element means in particular the least possible curvature, the lowest possible tensile forces and / or the lowest possible bending forces on the connecting element at a connection point on a connection device.
  • the position of the connection devices relative to the respective rail vehicle element to which it is fastened is preferably set passively.
  • the term “swivel joint” also includes joints which, in addition to rotation about an axis of rotation of the joint (Z axis, vertical axis), also permit movement by one or more other degrees of freedom.
  • rotation about a transverse axis can also be made possible with the swivel joint, so that the swivel joint in a special form is a swivel-pitch joint.
  • a rail vehicle element can be, for example, a locomotive or a train part, in particular a car, a car body or a module, of a rail vehicle.
  • the first and the second rail vehicle element are coupled in particular for the transmission of drive forces serving to move the rail vehicle elements, i.e. tensile or compressive forces, and at least about a vertical axis of rotation, e.g. runs perpendicular to a track bed, pivotable against each other in a predetermined angular range.
  • the hinge axis of rotation which is a vertical axis of rotation, is preferably arranged on a central longitudinal axis of the rail-bound means of transport and extends perpendicular to a track bed or a track plane.

  • each of the connection devices can be pivotable relative to a rail vehicle element on which it is mounted (described below), which results in further degrees of freedom of rotation.
  • the angle of the pivoting of a first rail vehicle element in the direction of travel against a following second rail vehicle element is defined as the angle between the longitudinal axis of the first rail vehicle element and the central longitudinal axis of the rail-bound means of transport when driving straight ahead.
  • the angle is negative when swiveled to the left, and positive when swiveled to the right.
  • the angular range of the pivoting is, for example, -40 ° to + 40 °.

  • the connecting element is connected to a first section of the connecting element, in particular to a first end of the connecting element, to the first connecting device and to a second section of the connecting element, in particular a second end of the connecting element, to the second connecting device.

  • the connection devices can avoid this movement by moving along their respective displacement axis in the direction of the inside of the curve, as a result of which the distance between the two connection devices is shortened again.

Description

Die Erfindung betrifft eine Verbindungsanordnung für mindestens ein flexibles Verbindungselement, insbesondere eines Verbindungselements zur Verbindung zweier Wagen eines schienengebundenen Verkehrsmittels, und ein Schienenfahrzeug mit einer solchen Verbindungsanordnung.The invention relates to a connection arrangement for at least one flexible connection element, in particular a connection element for connecting two cars of a rail-bound means of transport, and a rail vehicle with such a connection arrangement.

Im Schienenverkehr stellt sich das technische Problem, zwei zueinander bewegliche Elemente eines schienengebundenen Verkehrsmittels, insbesondere zwei gegeneinander rotierbare bzw. verschwenkbare Elemente miteinander zu verbinden. Bei schienengebundenen Verkehrsmitteln, beispielsweise Zügen, sind ein Triebwagen und ein Wagen oder zwei Wagen regelmäßig z. B. mittels Drehgelenk um eine vertikale Drehachse miteinander verschwenkbar gekoppelt, um Kurvenfahrten des Verkehrsmittels zu ermöglichen. Die Gelenke können auch als Dreh-Nickgelenk ausgeführt sein, um Fahrten über vertikale Radien (Kuppen und Wannen) zu ermöglichen.The technical problem arises in rail transport of connecting two mutually movable elements of a rail-bound means of transport, in particular two elements which can be rotated or pivoted relative to one another. In rail-bound means of transport, such as trains, a railcar and a car or two cars are regularly z. B. coupled by means of a swivel joint about a vertical axis of rotation to enable cornering of the means of transport. The joints can also be designed as a swivel-pitch joint in order to enable journeys over vertical radii (crests and troughs).

Es besteht der Bedarf, auch weitere Verbindungen zwischen den Elementen herzustellen. Weitere Verbindungen umfassen unter anderem Verbindungen zum Transport von Arbeitsmitteln, z. B. einer Bremsflüssigkeit, einer Kühlflüssigkeit, Druckluft oder elektrische Verbindungselemente zur Leitung elektrischer Energie. Hierzu geeignete Verbindungselemente können Kabel, Leitungen oder Schläuche sein. Diese werden entweder unterhalb der verbundenen Wagen bzw. unterhalb deren Wagenkästen geführt, wobei allerdings ein Sicherheitsabstand zur Schiene sowie zu einer Unterseite der Wagen einzuhalten ist, oder oberhalb der Wagen bzw. Wagenkästen am Dach, wobei wiederum Sicherheitsabstände zu beweglichen Teilen oder der Oberleitung einzuhalten sind.There is a need to make further connections between the elements. Other connections include connections for transporting work equipment, e.g. B. a brake fluid, a coolant, compressed air or electrical connecting elements for conducting electrical energy. Suitable connecting elements for this can be cables, lines or hoses. These are either routed below the connected wagons or below their wagon bodies, although a safety distance to the rail and to the underside of the wagons must be maintained, or above the wagons or wagon boxes on the roof, again keeping safety distances from moving parts or the overhead line ,

Hinsichtlich der Ausbildung und Halterung der Verbindungselemente ergeben sich folgende Rahmenbedingungen. Einerseits muss eine Länge der Verbindungselemente derart gewählt werden, dass auch bei maximaler Verschwenkung der verbundenen Elemente des Verkehrsmittels die Verbindung nicht abreißt. Die Länge des jeweiligen Verbindungselements ist somit abhängig von den maximalen Verdrehwinkeln sowie der Anordnung der zu verbindenden Anschlusseinrichtung bezüglich einer zentralen Längsachse des schienengebundenen Verkehrsmittels bei Geradeausfahrt. Die Anschlusseinrichtungen sind an den zu verbindenden Elementen des Verkehrsmittels angeordnete Einrichtungen, an welchen das Verbindungselement mechanisch fixiert bzw. mit denen das Verbindungselement mechanisch verbunden ist.The following general conditions result with regard to the design and mounting of the connecting elements. On the one hand, the length of the connecting elements must be selected such that the connection does not break even when the connected elements of the means of transport are pivoted to the maximum. The length of the respective connecting element is thus dependent on the maximum angles of rotation and the arrangement of the connecting device to be connected with respect to a central longitudinal axis of the rail-bound means of transport when driving straight ahead. The connection devices are on the elements of the means of transport to be connected arranged devices to which the connecting element is mechanically fixed or to which the connecting element is mechanically connected.

Weiter muss eine Halterung ein Verschwenken, ein Nicken sowie ein Wanken der verbundenen Wagen erlauben. Weiter dürfen die Verbindungselemente nicht aus einem vorgegebenen Raum, der insbesondere nach unten Richtung Gleisbett oder Wagendach und seitlich begrenzt ist, herausragen, damit die Verbindungselemente keine Gefährdung darstellen können.A bracket must also allow pivoting, nodding and swaying of the connected wagons. Furthermore, the connecting elements must not protrude from a predetermined space, which is bounded in particular downwards towards the track bed or wagon roof and laterally, so that the connecting elements cannot pose a hazard.

EP 2495151 A1 offenbart eine Haltevorrichtung zur Halterung mindestens eines flexiblen Verbindungselements, wobei mittels des Verbindungselements zwei voneinander beabstandete und gegeneinander um eine Rotationsachse verschwenkbare Elemente verbindbar sind, insbesondere Wagen eines schienengebundenen Verkehrsmittels. Die Haltevorrichtung weist mindestens drei Glieder auf, wobei jedes Glied zwei Drehgelenke aufweist, Die Glieder sind mittels der Drehgelenke derart drehbar aneinander befestigt, dass die Glieder eine Gliederkette ausbilden, wobei Endglieder der Kette mittels eines ihrer Drehgelenke drehbar an einer Trägereinrichtung befestigt sind. Mindestens ein Glied ist als Halteglied ausgebildet, wobei das Halteglied eine Halteeinrichtung ausbildet oder eine Halteeinrichtung aufweist, wobei das flexible Verbindungselement mittels der Halteeinrichtung fest mit dem Halteglied verbindbar ist. Mit dieser Haltevorrichtung können zwei gegeneinander verschwenkbare Elemente so verbunden werden, dass ein notwendiger Durchhang der Verbindungselemente und somit auch ein erforderlicher Bauraum für diese Verbindungselemente reduziert wird. EP 2495151 A1 discloses a holding device for holding at least one flexible connecting element, wherein by means of the connecting element it is possible to connect two elements spaced apart from one another and pivotable relative to one another about an axis of rotation, in particular carriages of a rail-bound means of transport. The holding device has at least three links, each link having two swivel joints. The links are rotatably fastened to one another by means of the swivel joints in such a way that the links form a link chain, end links of the chain being rotatably fastened to a carrier device by means of one of their swivel joints. At least one member is designed as a holding member, the holding member forming a holding device or having a holding device, the flexible connecting element being able to be fixedly connected to the holding member by means of the holding device. With this holding device, two elements which can be pivoted relative to one another can be connected in such a way that a necessary sag of the connecting elements and thus also a required installation space for these connecting elements is reduced.

Die Anbindung von Verbindungselementen im Bereich von Fahrzeuggelenken führt aber nach wie vor zu dem Problem der Verbiegung der Verbindungselemente im Bereich der Enden der Verbindungselemente wenn Schienenfahrzeugelemente, wie z.B. Wagen, um die Gelenkdrehachse gegeneinander verschwenkt werden. Diese Verbiegung, die im Extremfall zu einem Abknicken führen kann beeinträchtigt die Haltbarkeitsdauer der Verbindungselemente. Bisher wurden zur Lösung dieses Problems beispielsweise große Radien bei der Führung von Verbindungselementen gewählt und Verbindungselemente lang ausgelegt, sodass sie eine bei Geradeausfahrt große überschüssige Länge aufweisen, die bei Kurvenfahrt einer Kompensation der Abstandsänderung zwischen der ersten und der zweiten Anschlusseinrichtung dient. Diese überschüssige Länge führt allerdings zu einem großen Durchhang der Verbindungselemente, sodass Aufhängungen gegen ein zu großes Durchhängen erforderlich werden.However, the connection of connection elements in the area of vehicle joints still leads to the problem of the connection elements bending in the area of the ends of the connection elements when rail vehicle elements, such as, for example, carriages, are pivoted relative to one another about the axis of rotation of the joint. This bending, which in extreme cases can lead to kinking, affects the durability of the connecting elements. So far, to solve this problem, for example, large radii have been selected for the guidance of connecting elements and connecting elements have been designed to be long so that they have a large excess length when driving straight ahead, which serves to compensate for the change in distance between the first and the second connecting device when cornering. This excess length leads however, to a large sag of the connecting elements, so that suspensions against excessive sag are necessary.

Aufgabe der vorliegenden Erfindung ist es, für dieses Problem eine Lösung anzugeben. Insbesondere sollte eine Lösung angegeben werden, wie Verbindungsmittel möglichst kurz ausgeführt und dadurch eine überschüssige Länge reduziert werden kann.The object of the present invention is to provide a solution to this problem. In particular, a solution should be specified as to how the connecting means are made as short as possible and thereby an excess length can be reduced.

Die Aufgabe wird gelöst mit einer Verbindungsanordnung nach Anspruch 1.The object is achieved with a connection arrangement according to claim 1.

Nach einer grundlegenden Idee der Erfindung wird das Problem dadurch gelöst, dass eine erste Anschlusseinrichtung, an die ein flexibles Verbindungselement angeschlossen werden kann, drehbeweglich an einem ersten Schienenfahrzeugelement, beispielsweise einem Wagen, Wagenkasten oder Modul, gelagert ist und dass eine zweite Anschlusseinrichtung, an welche das flexible Verbindungselement angeschlossen werden kann, drehbeweglich an einem zweiten Schienenfahrzeugelement gelagert ist. Bei einer Drehung der Schienenfahrzeugelemente relativ zueinander um eine Gelenkdrehachse können die erste Anschlusseinrichtung und die zweite Anschlusseinrichtung relativ zu dem Schienenfahrzeugelement, an dem sie jeweils angebracht sind, so bewegt werden, dass eine Durchbiegung des Verbindungselements dort wo es an die Anschlusseinrichtungen angeschlossen ist vermindert oder eingeschränkt wird. Es kann insbesondere der Winkel zwischen einem ersten Endabschnitt des Verbindungselements und einem ersten Schienenfahrzeugelement und der Winkel zwischen einem zweiten Endabschnitt des Verbindungselements und einem zweiten Schienenfahrzeugelement verändert werden. Durch die bewegliche Lagerung der Anschlusseinrichtungen können die Anschlusseinrichtungen einer Drehbewegung bzw. Verschwenkung der Schienenfahrzeugelemente um eine Gelenkdrehachse entgegenwirken und im Extremfall, der aber nicht immer gegeben sein muss, kompensieren. Dies ist insbesondere der Fall, wenn die Anschlusseinrichtungen jeweils drehbar an einem Schienenfahrzeugelement gelagert sind. In diesem Fall können die Anschlusseinrichtungen eine Gegendrehbewegung zu der Drehung der Schienenfahrzeugelemente um eine Gelenkdrehachse ausführen.According to a basic idea of the invention, the problem is solved in that a first connection device, to which a flexible connecting element can be connected, is rotatably mounted on a first rail vehicle element, for example a carriage, car body or module, and in that a second connection device, to which the flexible connecting element can be connected, is rotatably mounted on a second rail vehicle element. When the rail vehicle elements are rotated relative to one another about an axis of rotation of the joint, the first connection device and the second connection device can be moved relative to the rail vehicle element to which they are respectively attached in such a way that deflection of the connecting element is reduced or restricted where it is connected to the connection devices becomes. In particular, the angle between a first end section of the connecting element and a first rail vehicle element and the angle between a second end section of the connecting element and a second rail vehicle element can be changed. Due to the movable mounting of the connection devices, the connection devices can counteract a rotary movement or swiveling of the rail vehicle elements about an axis of rotation of the joint and compensate in the extreme case, which does not always have to be the case. This is particularly the case if the connection devices are each rotatably mounted on a rail vehicle element. In this case, the connection devices can perform a counter-rotation movement to the rotation of the rail vehicle elements about an axis of rotation of the joint.

Nach einer Idee der Erfindung wird der Verlauf eines Verbindungselements zwischen Schienenfahrzeugelementen abhängig vom Drehwinkel zwischen den Schienenfahrzeugelementen, auch bezeichnet als Gelenkwinkel oder Verschwenkungswinkel, automatisch optimiert, indem infolge einer Drehung der Schienenfahrzeugelemente relativ zueinander um die Gelenkdrehachse sich die Lage jeder Anschlusseinrichtung relativ zu dem Schienenfahrzeugelement, an dem es beweglich gelagert ist, selbsttätig einstellt und eine optimierte Führung des Verbindungselements erreicht wird. Eine optimierte Führung des Verbindungselements bedeutet insbesondere eine möglichst geringe Krümmung, möglichst geringe Zugkräfte und/oder möglichst geringe Biegekräfte auf das Verbindungselement an einer Anschlussstelle an einer Anschlusseinrichtung. Infolge einer Verschwenkung der Schienenfahrzeugelemente relativ zueinander stellt sich die Lage der Anschlusseinrichtungen relativ zu dem jeweiligen Schienenfahrzeugelement, an dem sie befestigt ist, vorzugsweise passiv ein.According to an idea of the invention, the course of a connecting element between rail vehicle elements depends on the angle of rotation between the rail vehicle elements, also referred to as the joint angle or Swivel angle, automatically optimized in that, as a result of a rotation of the rail vehicle elements relative to one another about the axis of rotation of the joint, the position of each connection device relative to the rail vehicle element on which it is movably mounted adjusts itself automatically and an optimized guidance of the connecting element is achieved. Optimized guidance of the connecting element means in particular the least possible curvature, the lowest possible tensile forces and / or the lowest possible bending forces on the connecting element at a connection point on a connection device. As a result of a pivoting of the rail vehicle elements relative to one another, the position of the connection devices relative to the respective rail vehicle element to which it is fastened is preferably set passively.

Mit der Erfindung werden in ihrer allgemeinen oder in einer speziellen, nachfolgend noch beschriebenen Ausführungsform, insbesondere einer oder mehrere der folgenden Vorteile erzielt:

  • Erhöhung der Lebensdauer eines Verbindungselements.
  • Optimierte Führung eines Verbindungselements zwischen gelenkig gekoppelten Schienenfahrzeugelementen.
  • Optimierte Länge eines Verbindungselements, insbesondere Verkürzung der Länge eines Verbindungselements bei gleichzeitig geringem Durchhang nach unten bei Geradeausstellung der Schienenfahrzeugelemente. Durch eine verringerte Länge eines Verbindungselements ergeben sich Einsparungen an Material, Gewicht und Kosten.
  • Optimierter Gelenkswinkel. Eine Drehung von Schienenfahrzeugelementen relativ zueinander wird durch Verbindungselemente nicht oder weniger beschränkt.
  • Zusammenfassung der Spannungsniveaus.
  • Dickere Verkabelung verwendbar.
  • Keine/geringere Probleme mit Spezialkabeln (z.B. brüchige Coaxial-Kabel)
  • Auch für andere Systeme nutzbar wie Hydraulikleitungen und Wasserleitungen, die in wenig flexiblen Leitungen geführt werden.
  • Möglichkeit des "Auskreuzens" der Leitungen (Wechsel der Fahrzeugseite)
  • Vorkonfigurierte Anschlusseinrichtungen, d.h. beispielsweise eine Anordnung aus ein oder zwei Anschlusseinrichtungen mit einem oder mehreren angeschlossenen Verbindungselementen, sind auf einfache Weise beweglich an gekoppelten Schienenfahrzeugelementen montierbar. Es kann beispielsweise ein vorkonfiguriertes Set aus zwei Anschlusseinrichtungen und bereits angeschlossenem Verbindungselement, das die Anschlusseinrichtungen miteinander verbindet, eingebaut werden, indem jede der Anschlusseinrichtungen mit jeweils einem Schienenfahrzeugelement beweglich verbunden wird. Hierbei wird jeweils zwischen einer Anschlusseinrichtung und einem Schienenfahrzeugelement eine bewegliche Verbindung hergestellt.
  • Optimale Winkelausrichtung zwischen Verbindungselement und Fahrzeug. Der Winkel eines Endabschnitts des Verbindungselements gegenüber einer Wagenlängsachse ist einstellbar.
With the invention, in its general or in a special embodiment, which is described below, one or more of the following advantages are achieved:
  • Increase the life of a fastener.
  • Optimized guidance of a connecting element between articulated rail vehicle elements.
  • Optimized length of a connecting element, in particular shortening the length of a connecting element with a small sag downwards when the rail vehicle elements are in a straight line. A reduced length of a connecting element results in savings in material, weight and costs.
  • Optimized joint angle. A rotation of rail vehicle elements relative to one another is not or less restricted by connecting elements.
  • Summary of voltage levels.
  • Thicker cabling can be used.
  • No / less problems with special cables (e.g. brittle coaxial cables)
  • Can also be used for other systems such as hydraulic lines and water lines that run in less flexible lines.
  • Possibility of "crossing out" the lines (changing the vehicle side)
  • Preconfigured connection devices, that is to say, for example, an arrangement of one or two connection devices with one or more connected connection elements, can be mounted in a simple manner on coupled rail vehicle elements. For example, it can be a pre-configured one Set of two connection devices and an already connected connection element that connects the connection devices to one another can be installed by movably connecting each of the connection devices to a rail vehicle element. Here, a movable connection is established between a connection device and a rail vehicle element.
  • Optimal angular alignment between connecting element and vehicle. The angle of an end section of the connecting element with respect to a longitudinal axis of the carriage is adjustable.

Der Begriff "Drehgelenk" umfasst zum Zweck der Beschreibung dieser Erfindung auch Gelenke, die neben einer Drehung um eine Gelenkdrehachse (Z-Achse, vertikale Achse) auch eine Bewegung um einen oder mehrere andere Freiheitsgrade zulassen. Beispielsweise kann mit dem Drehgelenk auch eine Rotation um eine Querachse (Nickbewegung) ermöglicht sein, sodass das Drehgelenk in einer besonderen Ausprägung ein Dreh-Nickgelenk ist.For the purpose of describing this invention, the term “swivel joint” also includes joints which, in addition to rotation about an axis of rotation of the joint (Z axis, vertical axis), also permit movement by one or more other degrees of freedom. For example, rotation about a transverse axis (pitching movement) can also be made possible with the swivel joint, so that the swivel joint in a special form is a swivel-pitch joint.

Ein Schienenfahrzeugelement kann beispielsweise ein Triebfahrzeug oder ein Zugteil, insbesondere ein Wagen, ein Wagenkasten oder ein Modul, eines Schienenfahrzeugs sein. Das erste und das zweite Schienenfahrzeugelement sind insbesondere zur Übertragung von einer Bewegung der Schienenfahrzeugelemente dienenden Antriebskräften, also Zug- oder Druckkräften, gekoppelt und zumindest um eine vertikale Rotationsachse, die z.B. senkrecht zu einem Gleisbett verläuft, in einem vorbestimmten Winkelbereich gegeneinander verschwenkbar.A rail vehicle element can be, for example, a locomotive or a train part, in particular a car, a car body or a module, of a rail vehicle. The first and the second rail vehicle element are coupled in particular for the transmission of drive forces serving to move the rail vehicle elements, i.e. tensile or compressive forces, and at least about a vertical axis of rotation, e.g. runs perpendicular to a track bed, pivotable against each other in a predetermined angular range.

Bei einer Geradeausfahrt nehmen das erste und das zweite Schienenfahrzeugelement eine Ausgangsstellung ein, in dem ein Winkel einer Verschwenkung oder Verdrehung des ersten Schienenfahrzeugelements gegenüber dem zweiten Schienenfahrzeugelement 0° beträgt. Die Gelenkdrehachse, die eine vertikale Rotationsachse ist, ist vorzugsweise auf einer zentralen Längsachse des schienengebundenen Verkehrsmittels angeordnet und verläuft senkrecht zu einem Gleisbett oder einer Gleisebene. Es kann die Gelenkdrehachse mittig oder außermittig zwischen den beiden verbundenen Schienenfahrzeugelementen angeordnet sein.When driving straight ahead, the first and the second rail vehicle element assume an initial position in which an angle of pivoting or twisting of the first rail vehicle element relative to the second rail vehicle element is 0 °. The hinge axis of rotation, which is a vertical axis of rotation, is preferably arranged on a central longitudinal axis of the rail-bound means of transport and extends perpendicular to a track bed or a track plane. The pivot axis of rotation can be arranged centrally or off-center between the two connected rail vehicle elements.

Die Gelenkdrehachse, die eine vertikale Rotationsachse ist, wird auch als Z-Achse bezeichnet. Zusätzlich zu dieser Z-Achse können die Schienenfahrzeugelemente um eine oder mehrere weitere Drehachsen relativ zueinander drehbar sein. Weitere mögliche Drehachsen sind eine oben erwähnte zentrale Längsachse, die auch als X-Achse bezeichnet wird und eine Querachse, die auch als Y-Achse bezeichnet wird und insbesondere senkrecht zur X-Achse steht. Eine Verdrehung der Schienenfahrzeugelemente relativ zueinander um die X-Achse wird als Wankbewegung bezeichnet. Eine Verdrehung der Schienenfahrzeugelemente relativ zueinander um die Y-Achse wird als Nickbewegung bezeichnet.The hinge axis of rotation, which is a vertical axis of rotation, is also referred to as the Z axis. In addition to this Z axis, the rail vehicle elements can be rotatable relative to one another about one or more further axes of rotation. Other possible axes of rotation are a central longitudinal axis mentioned above, which is also referred to as the X axis, and a transverse axis, which is also referred to as the Y axis, and in particular is perpendicular to the X axis. A rotation of the rail vehicle elements relative to one another about the X axis is referred to as a rolling movement. A rotation of the rail vehicle elements relative to one another about the Y axis is referred to as a pitching movement.

Eine Anschlusseinrichtung ist insbesondere eine Einrichtung zur mechanischen Fixierung des Verbindungselements an einem Schienenfahrzeugelement, insbesondere zur mechanischen Fixierung eines Endes des Verbindungselements. Mit einer Anschlusseinrichtung wird das Verbindungselement an einem Schienenfahrzeugelement befestigt. Ferner können an den Anschlusseinrichtungen die Verbindungselemente zum Weitertransport von Arbeitsmitteln, z.B. einer Bremsflüssigkeit, einer Kühlflüssigkeit, Druckluft, oder zur Leitung elektrischer Energie kontaktiert sein. Ein spezielles Beispiel einer Anschlusseinrichtung ist ein Klemmkasten und ein zugehöriges Verbindungselement ist eine elektrische Leitung, die an oder in dem Klemmkasten mechanisch angebunden und elektrisch kontaktiert ist.A connection device is in particular a device for mechanically fixing the connecting element to a rail vehicle element, in particular for mechanically fixing one end of the connecting element. The connecting element is fastened to a rail vehicle element with a connecting device. Furthermore, the connecting elements for the further transport of work equipment, e.g. a brake fluid, a coolant, compressed air, or to conduct electrical energy. A specific example of a connection device is a terminal box and an associated connecting element is an electrical line that is mechanically connected to and electrically contacted on or in the terminal box.

Eine Anschlusseinrichtung ist beispielsweise plattenförmig oder kastenförmig ausgebildetA connection device is, for example, plate-shaped or box-shaped

Die erste und die zweite Anschlusseinrichtung sind beabstandet voneinander angeordnet und um die Gelenkdrehachse in einem vorbestimmten Winkelbereich gegeneinander, d.h. relativ zueinander, verschwenkbar. Diese Verschwenkbarbeit ergibt sich aus der Verschwenkbarkeit der Schienenfahrzeugelemente um die Gelenkdrehachse, wenn die erste Anschlusseinrichtung an dem ersten Schienenfahrzeugelement gelagert ist und die zweite Anschlusseinrichtung an dem zweiten Schienenfahrzeugelement gelagert ist. Zusätzlich zu dieser Verschwenkbarkeit der beiden Anschlusseinrichtungen relativ zueinander kann jede der Anschlusseinrichtungen relativ zu einem Schienenfahrzeugelement verschwenkbar sein, an dem es gelagert ist (nachfolgend noch beschrieben) wodurch sich weitere Rotationsfreiheitsgrade ergeben.The first and the second connection device are arranged at a distance from one another and can be pivoted relative to one another, ie relative to one another, about the axis of rotation of the joint in a predetermined angular range. This pivotability results from the pivotability of the rail vehicle elements about the axis of rotation when the first connection device is mounted on the first rail vehicle element and the second connection device is mounted on the second rail vehicle element. In addition to this pivotability of the two connection devices relative to one another, each of the connection devices can be pivotable relative to a rail vehicle element on which it is mounted (described below), which results in further degrees of freedom of rotation.

Der Winkel der Verschwenkung eines in Fahrtrichtung ersten Schienenfahrzeugelements gegen ein folgendes zweites Schienenfahrzeugelement wird definiert als Winkel zwischen Längsachse des ersten Schienenfahrzeugelements und der zentralen Längsachse des schienengebundenen Verkehrsmittels bei Geradeausfahrt. Bei Verschwenkung in Fahrtrichtung nach links ist der Winkel negativ, bei Verschwenkung nach rechts positiv. Der Winkelbereich der Verschwenkung ist beispielsweise -40° bis +40°, Der Winkelbereich ergibt sich allgemein in Abhängigkeit einer Vielzahl von Faktoren, unter anderem z.B. in Abhängigkeit einer Wagengeometrie, einer Gleisgeometrie, eines Kurvenradius und eines Abstandes der z.B. an verschiedenen Wagen angeordneten Anschlusseinrichtungen.The angle of the pivoting of a first rail vehicle element in the direction of travel against a following second rail vehicle element is defined as the angle between the longitudinal axis of the first rail vehicle element and the central longitudinal axis of the rail-bound means of transport when driving straight ahead. The angle is negative when swiveled to the left, and positive when swiveled to the right. The angular range of the pivoting is, for example, -40 ° to + 40 °. The angular range generally results from a number of factors, including e.g. depending on a car geometry, a track geometry, a curve radius and a distance e.g. connection devices arranged on different carriages.

Das Verbindungselement ist mit einem ersten Abschnitt des Verbindungselements, insbesondere mit einem ersten Ende des Verbindungselements, mit der ersten Anschlusseinrichtung und mit einem zweiten Abschnitt des Verbindungselements, insbesondere mit einem zweiten Ende des Verbindungselements, mit der zweiten Anschlusseinrichtung verbunden. Die Länge des Verbindungselements bestimmt sich unter anderem in Abhängigkeit eines Abstandes zwischen den Anschlusseinrichtungen, dem minimalen und dem maximalen Grenzwinkel, dem minimal und/oder maximal zulässigen Biegeradius des Verbindungselements, der Lage der Rotationsachse bezüglich der zu verbindenden Anschlusseinrichtungen, sowie der Art (rotatorisch, translatorisch, Lage der Bewegungsachse(n)) und dem Ausmaß der Beweglichkeit der ersten Anschlusseinrichtung relativ zu dem ersten Schienenfahrzeugelement und der Art und dem Ausmaß der Beweglichkeit der zweiten Anschlusseinrichtung relativ zu dem zweiten Schienenfahrzeugelement.The connecting element is connected to a first section of the connecting element, in particular to a first end of the connecting element, to the first connecting device and to a second section of the connecting element, in particular a second end of the connecting element, to the second connecting device. The length of the connecting element is determined, inter alia, as a function of a distance between the connecting devices, the minimum and maximum critical angle, the minimum and / or maximum permissible bending radius of the connecting element, the position of the axis of rotation with respect to the connecting devices to be connected, and the type (rotary, Translationally, position of the movement axis (s)) and the extent of the mobility of the first connection device relative to the first rail vehicle element and the type and extent of the mobility of the second connection device relative to the second rail vehicle element.

Das flexible Verbindungselement kann eine vorbestimmte Steifigkeit, insbesondere eine vorbestimmte Torsionssteifigkeit oder Biegesteifigkeit aufweisen. In einer Ausführungsform ist das flexible Verbindungselement als Schlauch oder Kabel oder Leitung ausgebildet. Hierdurch ergibt sich in vorteilhafter Weise, dass mittels des Verbindungselements Arbeitsmittel, z .B. Bremsflüssigkeit oder Luft, oder elektrische Energie zwischen den verbundenen Elementen transportiert werden kann.The flexible connecting element can have a predetermined rigidity, in particular a predetermined torsional rigidity or bending rigidity. In one embodiment, the flexible connecting element is designed as a hose or cable or line. This advantageously results in working means, e.g. Brake fluid or air, or electrical energy can be transported between the connected elements.

Nachfolgend wird auf die bewegliche Lagerung einer Anschlusseinrichtung an einem Schienenfahrzeugelement eingegangen. Die nachfolgenden Ausführungen betreffen sowohl Möglichkeiten der Lagerung der ersten Anschlusseinrichtung an dem ersten Schienenfahrzeugelement und Möglichkeiten der Lagerung der zweiten Anschlusseinrichtung an dem zweiten Schienenfahrzeugelement. Nachfolgend werden verkürzt die Begriffe "Anschlusseinrichtung" und "Schienenfahrzeugelement" verwendet.The movable mounting of a connection device on a rail vehicle element is discussed below. The following explanations relate both to possibilities of mounting the first connection device on the first Rail vehicle element and options for mounting the second connection device on the second rail vehicle element. The terms “connection device” and “rail vehicle element” are used in abbreviated form below.

Die Anschlusseinrichtung kann rotatorisch, also drehbar bzw. drehbeweglich, und/oder translatorisch, also verschiebbar, an dem Schienenfahrzeugelement gelagert sein. Bei einer drehbaren Lagerung kann die Anschlusseinrichtung um eine oder mehrere Drehachsen rotatorisch gelagert sein. Bei einer translatorischen Lagerung kann die Anschlusseinrichtung translatorisch in eine oder mehrere Raumrichtungen gelagert sein.The connecting device can be mounted on the rail vehicle element in a rotational, ie rotatable or rotatable, and / or translatory, ie displaceable. In the case of a rotatable mounting, the connection device can be mounted rotatably about one or more axes of rotation. In the case of a translational mounting, the connection device can be mounted translationally in one or more spatial directions.

Die Anschlusseinrichtung ist drehbeweglich an dem Schienenfahrzeugelement gelagert. Es ist die erste Anschlusseinrichtung drehbeweglich an dem ersten Schienenfahrzeugelement gelagert und/oder es ist die zweite Anschlusseinrichtung ist drehbeweglich an dem zweiten Schienenfahrzeugelement gelagert. Es ist die Anschlusseinrichtung drehbeweglich um eine Drehachse gelagert, die parallel zu der Gelenkdrehachse (Z-Achse) ist. Die erste Anschlusseinrichtung ist drehbeweglich um eine erste Drehachse gelagert, die parallel zu der Gelenkdrehachse ist, und/oder die zweite Anschlusseinrichtung ist drehbeweglich um eine zweite Drehachse gelagert, die parallel zu der Gelenkdrehachse ist. Bei der drehbeweglichen Lagerung um eine zur Gelenkdrehachse parallele Drehachse können sich Anschlusseinrichtungen bei einer Verschwenkung von Schienenfahrzeugelementen um die Gelenkdrehachse (beispielsweise bei einer Kurvenfahrt) besonders gut relativ zueinander ausrichten und es wird eine besonders günstige Führung des Verbindungselements zwischen den Schienenfahrzeugelementen ermöglicht, wie anhand eines Beispiels noch gezeigt.The connection device is rotatably mounted on the rail vehicle element. The first connection device is rotatably mounted on the first rail vehicle element and / or the second connection device is rotatably mounted on the second rail vehicle element. The connection device is rotatably mounted about an axis of rotation which is parallel to the axis of rotation of the joint (Z axis). The first connection device is rotatably supported about a first axis of rotation that is parallel to the axis of rotation of the joint, and / or the second connection device is rotatably supported about a second axis of rotation that is parallel to the axis of rotation of the joint. In the case of the rotatable mounting about an axis of rotation parallel to the axis of rotation of the joint, connection devices can align particularly well relative to one another when pivoting rail vehicle elements about the axis of rotation of the joint (for example when cornering), and particularly favorable guidance of the connecting element between the rail vehicle elements is made possible, as with the aid of an example still shown.

In einer Ausführungsform ist eine Anschlusseinrichtung außerdem drehbeweglich um eine Drehachse gelagert, die parallel zu einer Querachse des Schienenfahrzeugelements ist. Die Querachse des Schienenfahrzeugelements wird auch als Y-Achse bezeichnet und wurde oben definiert. Die Drehachse der Anschlusseinrichtung, die parallel zu dieser Querachse ist, wird auch als Nick-Achse bezeichnet. In dieser Ausführungsform können sich Anschlusseinrichtungen bei einer Nickbewegung der Schienenfahrzeugelemente, beispielsweise bei einer Fahrt durch eine Kuppe oder durch eine Senke, besonders vorteilhaft zueinander ausrichten. Einer oder mehrere Translations- und Einer oder mehrere Rotationsfreiheitsgrade sind beliebig miteinander kombinierbar. Somit ist diese Drehbeweglichkeit auch kombinierbar mit einer Drehbeweglichkeit der Anschlusseinrichtung um eine parallel zur Gelenkdrehachse stehende Achse.In one embodiment, a connection device is also rotatably mounted about an axis of rotation that is parallel to a transverse axis of the rail vehicle element. The transverse axis of the rail vehicle element is also referred to as the Y axis and was defined above. The axis of rotation of the connection device, which is parallel to this transverse axis, is also referred to as the pitch axis. In this embodiment, connection devices can align with one another particularly advantageously when the rail vehicle elements pitch, for example when driving through a crest or through a depression. One or more degrees of translation and one or more degrees of freedom of rotation can be combined with one another as desired. So this is Rotational mobility can also be combined with rotary mobility of the connection device about an axis parallel to the axis of rotation of the joint.

Wie oben bereits erwähnt kann die Anschlusseinrichtung translatorisch an dem Schienenfahrzeugelement gelagert sein. In einer besonders vorteilhaften Variante ist die Anschlusseinrichtung translatorisch in einer Richtung bzw. entlang einer Verschiebeachse gelagert, die parallel zu einer Querachse des Schienenfahrzeugelements ist. Bei dieser Ausführungsform ist bei einer Verschwenkung zweier Schienenfahrzeugteile zueinander, wie bei einer Kurvenfahrt, eine Annäherung zweier Anschlusseinrichtungen, die jeweils an einem der Schienenfahrzeugelemente angeordnet sind, möglich. Sind beispielsweise Anschlusseinrichtungen kurvenaußenseitig an den Schienenfahrzeugelementen angebracht, wird bei einer Kurvenfahrt der Abstand beider Anschlusseinrichtungen zueinander erhöht und ein Verbindungselement gestreckt. Dieser Bewegung können die Anschlusseinrichtungen dadurch ausweichen, dass sie sich entlang ihrer jeweiligen Verschiebeachse in Richtung Kurveninnenseite bewegen, wodurch der Abstand zwischen beiden Anschlusseinrichtungen wieder verkürzt wird.As already mentioned above, the connection device can be mounted translationally on the rail vehicle element. In a particularly advantageous variant, the connection device is mounted in a translatory manner in one direction or along an axis of displacement which is parallel to a transverse axis of the rail vehicle element. In this embodiment, when two rail vehicle parts are pivoted relative to one another, as when cornering, two connecting devices, which are each arranged on one of the rail vehicle elements, can be approached. If, for example, connection devices are attached to the outside of the curve on the rail vehicle elements, the distance between the two connection devices to one another is increased during cornering and a connecting element is stretched. The connection devices can avoid this movement by moving along their respective displacement axis in the direction of the inside of the curve, as a result of which the distance between the two connection devices is shortened again.

Bei der erfindungsgemäßen Verbindungsanordnung kann ein Lager vorgesehen sein, mit dem die Anschlusseinrichtung beweglich an dem betreffenden Schienenfahrzeugelement gelagert ist. Das Lager ist so ausgestaltet, dass es zumindest eine vorgesehene Rotationsbewegung und/oder zumindest eine vorgesehene Translationsbewegung der Anschlusseinrichtung relativ zu dem Schienenfahrzeugelement ermöglicht. Das Lager ist insbesondere ein Gleitlager oder ein Wälzlager.In the connection arrangement according to the invention, a bearing can be provided with which the connection device is movably mounted on the relevant rail vehicle element. The bearing is designed in such a way that it enables at least one rotational movement and / or at least one translational movement of the connection device relative to the rail vehicle element. The bearing is in particular a plain bearing or a roller bearing.

Die Anordnung der Anschlusseinrichtung an dem Schienenfahrzeugelement, an dem sie beweglich gelagert ist, kann an verschiedener Stelle erfolgen. Beispielsweise ist die Anschlusseinrichtung unterhalb oder oberhalb eines Drehgelenks oder Drehgelenkteils angeordnet. Im Falle eines Schienenfahrzeugwagens kann beispielsweise die Anschlusseinrichtung an einer Unterbaustruktur des Wagens beweglich gelagert sein, insbesondere an einem Querträger, insbesondere an einem End-Querträger. Alternativ oder zusätzlich kann eine Anschlusseinrichtung im Falle eines Schienenfahrzeugwagens im Dachbereich des Wagens angeordnet bzw. dort beweglich gelagert sein. Beispielsweise kann die Anschlusseinrichtung an einem Dachquerträger angeordnet bzw. dort beweglich gelagert sein.The connection device can be arranged on the rail vehicle element on which it is movably mounted at various points. For example, the connection device is arranged below or above a swivel joint or swivel joint part. In the case of a rail vehicle, for example, the connection device can be movably mounted on a substructure of the car, in particular on a cross member, in particular on an end cross member. Alternatively or additionally, in the case of a rail vehicle carriage, a connection device can be arranged in the roof area of the carriage or can be movably mounted there. For example, the connection device can be arranged on a roof cross member or be movably mounted there.

In einer Ausführungsform weist die Verbindungsanordnung mehrere flexible Verbindungselemente auf. Diese mehreren Verbindungselemente sind jeweils mit einem ersten Abschnitt, vorzugsweise mit einem ersten Ende, mit der ersten Anschlusseinrichtung verbunden und mit einem zweiten Abschnitt, insbesondere mit einem zweiten Ende, mit der zweiten Anschlusseinrichtung verbunden. In dieser Ausführungsform sind somit mehrere Verbindungselemente gebündelt zu einer ersten Anschlusseinrichtung und einer zweiten Anschlusseinrichtung geführt bzw. gebündelt zwischen diesen Anschlusseinrichtungen angeordnet. Diese Ausführungsform ist besonders vorteilhaft, weil bei einer Bündelung von Verbindungselementen die Verbiegung oder Torsion des Bündels bei einer Verschwenkung der Schienenfahrzeugelemente zueinander besonders ins Gewicht fällt. Biegesteifigkeiten bzw. Torsionssteifigkeiten addieren sich in dem Bündel und man erhält in der Regel eine besonders biege- oder torsionssteife Struktur. Ferner können sich in einem Bündel von Verbindungselementen bei einer Verbiegung oder Torsion einzelne Verbindungselemente in ihrer Bewegung gegenseitig beeinflussen. Diese Effekte werden durch die erfindungsgemäße Maßnahme, die Anschlusseinrichtung(en) beweglich an einem jeweiligen Schienenfahrzeugteil zu lagern, deutlich gemildert. In dieser Ausführungsform sind die Verbindungselemente vorzugsweise elektrische Leitungen, insbesondere mehradrige Kabel, oder Leitungen, insbesondere Schläuche, für flüssige Arbeitsmedien, insbesondere Hydraulikflüssigkeit oder Wasser.In one embodiment, the connection arrangement has a plurality of flexible connection elements. These multiple connecting elements are each connected to the first connection device with a first section, preferably with a first end, and connected to the second connection device with a second section, in particular with a second end. In this embodiment, a plurality of connection elements are thus bundled to form a first connection device and a second connection device or are arranged in a bundle between these connection devices. This embodiment is particularly advantageous because, when connecting elements are bundled, the bending or torsion of the bundle is particularly important when the rail vehicle elements are pivoted relative to one another. Bending stiffnesses or torsional stiffnesses add up in the bundle and one usually obtains a structure that is particularly resistant to bending or torsion. Furthermore, the movement of individual connecting elements in a bundle of connecting elements in the event of bending or torsion can influence one another. These effects are significantly alleviated by the measure according to the invention of movably mounting the connection device (s) on a respective rail vehicle part. In this embodiment, the connecting elements are preferably electrical lines, in particular multi-core cables, or lines, in particular hoses, for liquid working media, in particular hydraulic fluid or water.

In einer Ausführungsform wird eine Verbindungsanordnung angegeben, wobei

  • die erste Anschlusseinrichtung zumindest ein erstes Anschlussmittel aufweist, an welches das flexible Verbindungselement anschließbar ist,
  • die zweite Anschlusseinrichtung zumindest ein zweites Anschlussmittel aufweist, an welches das flexible Verbindungselement anschließbar ist,
wobei das erste Anschlussmittel und das zweite Anschlussmittel aufeinander ausrichtbar sind.In one embodiment, a connection arrangement is specified, wherein
  • the first connection device has at least one first connection means to which the flexible connecting element can be connected,
  • the second connection device has at least one second connection means to which the flexible connecting element can be connected,
wherein the first connection means and the second connection means can be aligned with one another.

Durch die bewegliche Lagerung der Anschlusseinrichtungen können die Anschlussmittel zueinander orientiert werden bzw. aufeinander ausgerichtet werden. Wenn die Schienenfahrzeugelemente um die Gelenkdrehachse gegeneinander verschwenkt werden, können die Anschlussmittel zueinander orientiert werden. Dies bedeutet insbesondere, dass die Anschlusseinrichtungen beider Anschlusseinrichtungen in eine gegenüber liegende Lage gebracht werden können. Dadurch ist ein günstiger Verlauf eines Verbindungselements, das an die Anschlusseinrichtungen angeschlossen ist, erreichbar.Due to the movable mounting of the connection devices, the connection means can be oriented towards one another or aligned with one another. If the rail vehicle elements are pivoted relative to one another about the axis of rotation of the joint, the connecting means can be oriented relative to one another. This means in particular that the connection devices of both connection devices can be brought into an opposite position. This is a favorable course of a connecting element that is connected to the connection devices can be reached.

In einem weiteren Aspekt betrifft die Erfindung auch ein Schienenfahrzeug oder einen Schienenfahrzeugverbund, aufweisend eine Verbindungsanordnung wie vorangehend beschrieben. Der Schienenfahrzeugverbund wird aus mehreren Schienenfahrzeugelementen, insbesondere Wagen, Triebwagen, Wagons, Modulen, gebildet. Der Schienenfahrzeugverbund ist insbesondere eine U-Bahn, S-Bahn, Straßenbahn, ein Nahverkehrszug oder ein Fernverkehrszug.In a further aspect, the invention also relates to a rail vehicle or a rail vehicle group, comprising a connection arrangement as described above. The rail vehicle network is formed from several rail vehicle elements, in particular wagons, railcars, wagons, modules. The rail vehicle network is in particular a subway, S-Bahn, tram, a local train or a long-distance train.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert. Es zeigen:

Die Verbindungsanordnung 1 in Fig. 1 weist das erste Schienenfahrzeugelement 2 und das zweite Schienenfahrzeugelement 3 auf. Die Schienenfahrzeugelemente 2, 3 sind Wagenkästen, beispielsweise von Wagons, und anhand einiger Rohbauelemente skizziert, die nachfolgend noch beschrieben sind.The connection arrangement 1 in Fig. 1 has the first rail vehicle element 2 and the second rail vehicle element 3. The rail vehicle elements 2, 3 are car bodies, for example of wagons, and are sketched using a few structural elements which are described below.

Zwischen dem ersten Schienenfahrzeugelement 2 und dem zweiten Schienenfahrzeugelement 3 ist ein Drehgelenk 4 angeordnet, über welches die Schienenfahrzeugelemente 2, 3 aneinander gekoppelt sind. Das Gelenk 4 weist die Gelenkteile 5 und 6 auf. Das Gelenkteil 5 ist an dem ersten Schienenfahrzeugelement 2 angebracht und in diesem Beispiel mit einem Endquerträger 7 verbunden. Das Gelenkteil 6 ist mit dem Endquerträger 8 des zweiten Schienenfahrzeugelements 3 verbunden. Die Gelenkteile 5, 6 sind um die Gelenkdrehachse Z, die senkrecht zur Zeichnungsebene steht, relativ zueinander drehbar, sodass auch die Schienenfahrzeugelemente 2 und 3 um die Achse Z, die eine Vertikalachse ist, drehbar sind.A swivel joint 4 is arranged between the first rail vehicle element 2 and the second rail vehicle element 3, via which the rail vehicle elements 2, 3 are coupled to one another. The joint 4 has the joint parts 5 and 6. The joint part 5 is attached to the first rail vehicle element 2 and in this example is connected to an end cross member 7. The joint part 6 is connected to the end cross member 8 of the second rail vehicle element 3. The hinge parts 5, 6 can be rotated relative to one another about the hinge axis of rotation Z, which is perpendicular to the plane of the drawing, so that the rail vehicle elements 2 and 3 can also be rotated about the axis Z, which is a vertical axis.

Der Wagen 2 weist in der Rohbaustruktur u.a. einen Endquerträger 7 und Längsträger 17, 18 auf, die sich an den Endquerträger 7 anschließen. Der Wagen 3 weist in seiner Rohbaustruktur u.a. den Endquerträger 8 und die Längsträger 19, 20 auf, die an den Endquerträger 8 anschließen. Auf diese Rohbaustruktur können Wagenkastenseiten und Endwände aufgesetzt sein, wie in Fig. 3 nachfolgend noch gezeigt.The carriage 2 has in the bodyshell structure, inter alia, an end cross member 7 and longitudinal members 17, 18 which adjoin the end cross member 7. The body 3 of the carriage 3 has, among other things, the end cross member 8 and the longitudinal members 19, 20 which connect to the end cross member 8. Wagon body sides and end walls can be placed on this bodyshell structure, as in Fig. 3 shown below.

An dem Endquerträger 7 des ersten Schienenfahrzeugelements 2 ist die erste Anschlusseinrichtung 9 angebracht. An dem Endquerträger 8 des zweiten Schienenfahrzeugelements 3 ist die zweite Anschlusseinrichtung 10 angebracht.The first connection device 9 is attached to the end cross member 7 of the first rail vehicle element 2. The second connection device 10 is attached to the end cross member 8 of the second rail vehicle element 3.

Die erste Anschlusseinrichtung 9 ist relativ zu dem ersten Schienenfahrzeugelement 2 beweglich. Sie ist beweglich an dem Endquerträger 7 gelagert, wie nachfolgend noch beschrieben wird. Die zweite Anschlusseinrichtung 10 ist relativ beweglich zu dem zweiten Schienenfahrzeugelement 3. Sie ist beweglich an dem Endquerträger 8 gelagert, wie nachfolgend noch beschrieben wird.The first connection device 9 is movable relative to the first rail vehicle element 2. It is movably mounted on the end cross member 7, as will be described below. The second connection device 10 is movable relative to the second rail vehicle element 3. It is movably mounted on the end cross member 8, as will be described below.

Die erste Anschlusseinrichtung 9 weist die Anschlussmittel 11 und 12 auf, die beispielsweise an Klemmstellen für elektrische Leitungen oder Anschlussstellen für Schläuche sind. In analoger Weise weist die zweite Anschlusseinrichtung 10 zwei Anschlussmittel 13, 14 auf. Je Anschlusseinrichtung 9, 10 sind in diesem Beispiel nur zwei Anschlussmittel dargestellt. Alternativ dazu können noch weitere Anschlussmittel vorgesehen sein oder nur ein Anschlussmittel je Anschlusseinrichtung vorgesehen sein. Gezeigt sind ferner zwei flexible Verbindungselemente 15, 16. Die Verbindungselemente 15, 16 sind beispielsweise elektrische Leitungen oder Schläuche für flüssige Arbeitsmedien, insbesondere Hydraulikschläuche. Ein Verbindungselement wird nachfolgend auch als Verbindungsmittel bezeichnet.The first connection device 9 has the connection means 11 and 12, which are, for example, at clamping points for electrical lines or connection points for hoses. In an analogous manner, the second connection device 10 has two connection means 13, 14. In this example, only two connection means are shown for each connection device 9, 10. Alternatively, further connection means can be provided or only one connection means per connection device can be provided. Two flexible connecting elements 15, 16 are also shown. The connecting elements 15, 16 are, for example, electrical lines or hoses for liquid working media, in particular hydraulic hoses. A connecting element is also referred to below as a connecting means.

Das Verbindungsmittel 15 erstreckt sich von der Anschlusseinrichtung 9 zu der Anschlusseinrichtung 10, genau gesagt von dem Anschlussmittel 11 der ersten Anschlusseinrichtung 9 bis zu dem Anschlussmittel 13 der zweiten Anschlusseinrichtung 10. In analoger Weise erstreckt sich das zweite Verbindungselement 16 von dem Anschlussmittel 12 der ersten Anschlusseinrichtung 9 zu dem Anschlussmittel 14 der zweiten Anschlusseinrichtung 10. An den Anschlussmitteln 11, 12, 13, 14 sind die Verbindungsmittel 15, 16, beispielsweise angeklemmt oder angeschraubt, was hier nicht näher dargestellt ist.The connecting means 15 extends from the connecting device 9 to the connecting device 10, to be precise from the connecting device 11 of the first connecting device 9 to the connecting device 13 of the second connecting device 10. In an analogous manner, the second connecting element 16 extends from the connecting means 12 of the first connecting device 9 to the connecting means 14 of the second connecting device 10. The connecting means 15, 16 are attached to the connecting means 11, 12, 13, 14, for example clamped or screwed on, which is not shown here.

Durch die Verbindungsmittel 15, 16 kann beispielsweise Strom oder Arbeitsmedium von dem Wagen 2 zu dem Wagen 3 geleitet werden oder umgekehrt. Der Weitertransport eines durch die Verbindungsmittel 15, 16 geleiteten Arbeitsmediums oder elektrischen Stroms innerhalb der Wagen 2, 3 ist hier nicht weiter dargestellt.The connecting means 15, 16 can, for example, conduct electricity or working medium from the carriage 2 to the carriage 3 or vice versa. The further transport of a working medium or electrical current conducted through the connecting means 15, 16 within the carriages 2, 3 is not shown further here.

Fig. 1 zeigt die Wagen 2, 3 in Geradeausstellung. Die Wagenlängsachse X1 des ersten Wagens 2 und die Wagenlängsachse X2 des zweiten Wagens 3 liegen auf einer Flucht und bilden in dieser Geradeausstellung die Schienenfahrzeuglängsachse. Fig. 1 shows the cars 2, 3 in the straight-ahead position. The longitudinal axis X1 of the first carriage 2 and the longitudinal axis X2 of the second carriage 3 lie in alignment and form the longitudinal axis of the rail vehicle in this straight-ahead position.

Der erste Wagen 2 weist ferner die Querachse Y1 auf und der zweite Wagen 3 weist die Querachse Y2 auf. Die Querachsen Y1, Y2 stehen senkrecht zu den Längsachsen X1 bzw. X2. Die Querachsen Y1 und Y2 sind in Geradeausstellung der Wagen 2, 3 parallel zu der Gelenkquerachse Y3, die wiederum senkrecht zu der Vertikalachse Z ist. Eine relative Drehung der Wagen 2 und 3 um die Achse Y3 wird als Nickbewegung bezeichnet. Die Z-Achse wird erfindungsgemäß jedoch als Gelenkdrehachse bezeichnet, da sie die Drehbewegung der Wagen 2, 3 relativ zueinander bei einer Kurvenfahrt, und damit die wichtigste Gelenkbewegung, ermöglicht. Die Drehbewegung beispielsweise bei einer Kurvenfahrt wird somit begrifflich von der eben beschriebenen Nickbewegung unterschieden. Der Vollständigkeit halber erwähnt sei noch die Wankbewegung um die Schienenfahrzeuglängsachse, welche in Geradeausstellung aus den Achsen X1 und X2 gebildet wird. Bei der Wankbewegung verdrehen sich die Wagen 2 und 3 relativ zueinander entlang dieser Schienenfahrzeuglängsachse.The first carriage 2 also has the transverse axis Y1 and the second carriage 3 has the transverse axis Y2. The transverse axes Y1, Y2 are perpendicular to the longitudinal axes X1 and X2. The transverse axes Y1 and Y2 are in the straight-ahead position of the carriages 2, 3 parallel to the joint transverse axis Y3, which in turn is perpendicular to the vertical axis Z. A relative rotation of the carriages 2 and 3 about the axis Y3 is referred to as the pitching movement. According to the invention, however, the Z axis is referred to as the articulation axis of rotation, since it enables the rotation of the carriages 2, 3 relative to one another when cornering, and thus the most important articulation movement. The rotational movement, for example when cornering, is thus conceptually distinguished from the pitching movement just described. For the sake of completeness, the roll movement about the longitudinal axis of the rail vehicle, which is formed in the straight-ahead position from the axes X1 and X2, should also be mentioned. During the roll movement, the carriages 2 and 3 rotate relative to one another along this longitudinal axis of the rail vehicle.

Nachfolgend wird die Bewegung der Anschlusseinrichtungen 9, 10 relativ zu den Wagen 2 bzw. 3 beschrieben.The movement of the connection devices 9, 10 relative to the carriages 2 and 3 is described below.

Die Anschlusseinrichtung 9 ist drehbeweglich um die senkrecht zur Zeichnungsebene und parallel zur Z-Achse stehende Drehachse D1 gelagert. Die Anschlusseinrichtung 10 ist drehbar um die Achse D2 gelagert, die ebenfalls parallel zu der Z-Achse, also der Gelenkdrehachse, steht. Weiterhin ist in diesem Beispiel die erste Anschlusseinrichtung 9 auch drehbar um die Achse D3 gelagert, die parallel zu der Querachse Y1 des ersten Wagens 2 ist. In analoger Weise ist die zweite Anschlusseinrichtung 10 drehbar um die Querachse D4 gelagert, die parallel zu der Querachse Y2 des zweiten Wagens 3 ist. Ein möglicher Drehwinkel um die Drehachsen D1, D2, D3, D4 kann begrenzt sein, beispielsweise durch einen Anschlag, was aber nicht zwingend ist. Der mögliche Drehwinkel um diese Achsen kann sich durch die Anordnung und Steifigkeit der Verbindungselemente 15, 16 und durch den Drehwinkel um die Gelenkdrehachse Z oder den maximalen Drehwinkel um die Gelenkdrehachse Z ergeben.The connection device 9 is rotatably mounted about the axis of rotation D1 which is perpendicular to the plane of the drawing and parallel to the Z-axis. The connection device 10 is rotatably mounted about the axis D2, which is also parallel to the Z axis, that is Joint axis of rotation, stands. Furthermore, in this example, the first connection device 9 is also rotatably supported about the axis D3, which is parallel to the transverse axis Y1 of the first carriage 2. In an analogous manner, the second connection device 10 is rotatably mounted about the transverse axis D4, which is parallel to the transverse axis Y2 of the second carriage 3. A possible angle of rotation about the axes of rotation D1, D2, D3, D4 can be limited, for example by a stop, but this is not mandatory. The possible angle of rotation about these axes can result from the arrangement and rigidity of the connecting elements 15, 16 and from the angle of rotation about the axis of rotation Z or the maximum angle of rotation about the axis of rotation Z.

An dem Endquerträger 7 des ersten Wagens 2 ist ferner ein Gleitlager 21 ausgebildet, das ein Linearlager ist, in dem die erste Anschlusseinrichtung 9 translatorisch beweglich ist. Das Linearlager 21 ist beispielsweise in Form einer Nut oder Schiene ausgebildet, in welcher ein komplementär ausgebildetes Gleitelement, das mit der ersten Anschlusseinrichtung 9 verbunden ist, verschiebbar ist. Insbesondere ist das Gleitlager 21 als C-Schiene ausgebildet, in welcher ein Gleitelement, das von der Schiene umgriffen wird, verschiebbar ist. In analoger Weise ist an dem Endquerträger 8 des zweiten Wagens 3 ein Gleitlager 22 ausgebildet. Die Gleitlager 21, 22 sind in diesem Beispiel über annähernd die gesamte Breite des Wagens 2 bzw. des Wagens 3 ausgeführt. Selbstverständlich ist es möglich, sich weniger in der Breite erstreckende Lager 21, 22 vorzusehen und das mögliche Ausmaß einer Translationsbewegung der ersten Anschlusseinrichtung 9 und der zweiten Anschlusseinrichtung 10 zu begrenzen. Beispielsweise kann ein Lager 21 oder 22 nur maximal bis zur Mittelachse X1 bzw. X2 ausgeführt sein. Es kann die Kombination aller drei Bewegungsmöglichkeiten ausgeführt sein (Drehachse D1, Drehachse D3 und Gleitlager 21) oder auch nur zwei Kombinationen oder nur eine Bewegungsmöglichkeit.On the end cross member 7 of the first carriage 2, a slide bearing 21 is also formed, which is a linear bearing in which the first connection device 9 is translationally movable. The linear bearing 21 is designed, for example, in the form of a groove or rail, in which a complementary sliding element, which is connected to the first connection device 9, can be displaced. In particular, the slide bearing 21 is designed as a C-rail, in which a sliding element which is gripped by the rail can be displaced. In a similar manner, a slide bearing 22 is formed on the end cross member 8 of the second carriage 3. The slide bearings 21, 22 are executed in this example over almost the entire width of the carriage 2 or the carriage 3. Of course, it is possible to provide bearings 21, 22 that extend less in width and to limit the possible extent of a translational movement of the first connection device 9 and the second connection device 10. For example, a bearing 21 or 22 can only be designed at most up to the central axis X1 or X2. The combination of all three movement possibilities can be carried out (rotation axis D1, rotation axis D3 and slide bearing 21) or only two combinations or only one movement possibility.

Fig. 2 zeigt die Situation nach einer Drehbewegung der Wagen 2 und 3 um die Gelenkdrehachse Z. Beispielsweise wird in der mit einem Pfeil dargestellten Fahrtrichtung F eine Linkskurve durchfahren und es findet eine Drehung bzw. Verschwenkung der Wagen 2 und 3 relativ zueinander statt. In der Fig. 2 sind die gleichen Bezugszeichen für gleiche Elemente gewählt wie in Fig. 1. Fig. 2 shows the situation after a rotary movement of the carriages 2 and 3 about the articulation axis of rotation Z. For example, a left turn is traversed in the direction of travel F represented by an arrow and the carriages 2 and 3 are rotated or pivoted relative to one another. In the Fig. 2 the same reference numerals are chosen for the same elements as in Fig. 1 ,

Infolge der Drehung der Wagen 2, 3 relativ zueinander um die Gelenkdrehachse Z wird der erste Gelenkteil 5 entgegen Uhrzeigersinn gegen den zweiten Gelenkteil 6 gedreht. Dies ist durch den Pfeil oberhalb der Z-Achse dargestellt.As a result of the rotation of the carriages 2, 3 relative to one another about the pivot axis Z, the first pivot part 5 is rotated counterclockwise against the second pivot part 6. This is shown by the arrow above the Z axis.

Auch die Anschlusseinrichtungen 9, 10 werden relativ zueinander um die Gelenkdrehachse Z verschwenkt und dadurch der Abstand zwischen der ersten Anschlusseinrichtung 9 und der zweiten Anschlusseinrichtung 10 vergrößert. Bei der umgekehrten Drehrichtung der Wagen 2, 3 relativ zueinander würde der Abstand zwischen den Anschlusseinrichtungen 9, 10 verringert. Durch die Vergrößerung des Abstandes werden die flexiblen Verbindungselemente 15, 16 gegenüber der Ausgangslage in Fig. 1 gestreckt. Diese Streckung wird durch eine überschüssige Länge ermöglicht bzw. aufgefangen. In Fig. 1 ist eine überschüssige Länge der Verbindungselemente 15, 16 in Form einer seitlichen Krümmung erkennbar. In Fig. 2, im gestreckten Zustand, ist der Krümmung verringert. Zusätzlich zu einer Streckung der Verbindungselemente 15, 16 findet eine Bewegung der ersten Anschlusseinrichtung 9 relativ zu dem ersten Wagen 2 und eine Bewegung der zweiten Anschlusseinrichtung 10 relativ zu dem zweiten Wagen 3 statt. Die erste Anschlusseinrichtung 9 vollzieht eine Drehung im Uhrzeigersinn, also entgegen der Drehung des ersten Wagens 2 relativ zu einem als stationär betrachteten zweiten Wagen 3. In analoger Weise vollzieht die zweite Anschlusseinrichtung 10 eine Drehbewegung um die Drehachse D2, allerdings entgegen dem Uhrzeigersinn. Die erste Anschlusseinrichtung 9 und die zweite Anschlusseinrichtung 10 drehen sich also aufeinander zu. Die Drehung des zweiten Anschlusselements 10 im Gegenuhrzeigersinn ist gegenläufig zu einer Drehung des zweiten Wagens 3 relativ zu einem als stationär betrachteten ersten Wagen 2, die im Uhrzeigersinn stattfindet und die durch einen Pfeil an dem Gelenkteil 6 dargestellt ist.The connection devices 9, 10 are also pivoted relative to one another about the axis of rotation Z, thereby increasing the distance between the first connection device 9 and the second connection device 10. With the reverse direction of rotation of the carriages 2, 3 relative to one another, the distance between the connection devices 9, 10 would be reduced. By increasing the distance, the flexible connecting elements 15, 16 are in relation to the starting position in Fig. 1 stretched. This stretching is made possible or absorbed by an excess length. In Fig. 1 an excessive length of the connecting elements 15, 16 can be seen in the form of a lateral curvature. In Fig. 2 , when stretched, the curvature is reduced. In addition to extending the connecting elements 15, 16, the first connection device 9 moves relative to the first carriage 2 and the second connection device 10 moves relative to the second carriage 3. The first connection device 9 rotates clockwise, that is, counter to the rotation of the first carriage 2 relative to a second carriage 3, which is regarded as stationary. In an analogous manner, the second connection device 10 rotates about the axis of rotation D2, but counterclockwise. The first connection device 9 and the second connection device 10 thus rotate towards one another. The rotation of the second connection element 10 in the counterclockwise direction is counter to a rotation of the second carriage 3 relative to a first carriage 2, which is considered stationary, which takes place clockwise and which is represented by an arrow on the joint part 6.

Weiterhin wird die Anschlusseinrichtung 9 in dem Gleitlager 21 in Richtung Wagenmitte, in Richtung Mittellängsachse X1, verschoben. In analoger Weise wird die zweite Anschlusseinrichtung 10 ebenfalls in Richtung Wagenmitte des zweiten Wagens 3, in Richtung seiner Mittellängsachse X2, verschoben. Die gezeigte Translation der ersten Anschlusseinrichtung 9 erfolgt parallel zu der Querachse Y1. Die Translation der zweiten Anschlusseinrichtung 10 erfolgt parallel zu der Querachse Y2.Furthermore, the connection device 9 is displaced in the slide bearing 21 in the direction of the center of the carriage, in the direction of the central longitudinal axis X1. In an analogous manner, the second connection device 10 is also displaced in the direction of the middle of the second carriage 3, in the direction of its central longitudinal axis X2. The translation of the first connection device 9 shown takes place parallel to the transverse axis Y1. The second connection device 10 is translated parallel to the transverse axis Y2.

Erfindungsgemäß müssen die Translationsbewegung und Rotationsbewegung einer Anschlusseinrichtung 9 bzw. 10 nicht miteinander kombiniert werden. Es kann auch lediglich eine Translationsbewegung oder lediglich eine Rotationsbewegung vorgesehen sein. Ferner kann eine Translation oder Rotation zusätzlich oder alternativ um eine oder mehrere weitere Rotations- bzw. Translationsachsen vorgesehen sein. Im vorliegenden Beispiel ist als zusätzliche Rotationsachse für das erste Anschlusselement die Achse D3 vorgesehen und als zusätzliche Rotationsachse für das zweite Anschlusselement 10 die Rotationsachse D4. Die Rotation um die Achsen D3 bzw. D4 ist bei einer Nickbewegung der Wagen 2 und 3 relativ zueinander vorteilhaft.According to the invention, the translational movement and the rotational movement of a connecting device 9 or 10 do not have to be combined with one another. It can also only a translational movement or only a rotational movement can be provided. Furthermore, a translation or rotation can additionally or alternatively be provided about one or more further axes of rotation or translation. In the present example, the axis D3 is provided as an additional axis of rotation for the first connection element and the axis of rotation D4 as an additional axis of rotation for the second connection element 10. The rotation about the axes D3 or D4 is advantageous in the case of a pitching movement of the carriages 2 and 3 relative to one another.

Es kann ferner vorgesehen sein, dass nur eine der Anschlusseinrichtungen 9 oder 10 relativ um eine oder mehrere Translations- und/oder Rotationsachsen relativ zu dem Wagenteil 2 oder 3, an dem sie angeordnet ist, beweglich ist.It can further be provided that only one of the connection devices 9 or 10 is movable relative to one or more translation and / or rotation axes relative to the carriage part 2 or 3 on which it is arranged.

Durch die zuvor beschriebene Bewegung der ersten Anschlusseinrichtung 9 und der zweiten Anschlusseinrichtung 10 relativ zu dem Wagen 2 bzw. 3 ergibt sich Folgendes: die Anschlussmittel 11, 12 der ersten Anschlusseinrichtung 9 einerseits und die Anschlussmittel 13, 14 der zweiten Anschlusseinrichtung 10 werden aufeinander ausgerichtet, sodass sich im günstigsten Fall die gleiche Ausrichtung ergeben kann wie im nicht verschwenkten Zustand der Wagen 2, 3 in der Fig. 1. Dadurch werden ein erster Abschnitt 23 des Verbindungselements 16 und ein erster Abschnitt 24 des Verbindungselements 15 weniger auf Biegung beansprucht. Insbesondere werden Enden der Verbindungselemente 15, 16, die an den Anschlussmitteln 11, 12 angebracht sind, weniger an den Ansatzstellen verbogen oder geknickt. Ebenso werden zweite Abschnitte 25, 26 weniger verbogen und gegenüberliegende Enden der Verbindungselemente 15, 16, die an den Anschlussmitteln 13, 14 angeschlossen sind, weniger geknickt.The previously described movement of the first connection device 9 and the second connection device 10 relative to the carriage 2 and 3 results in the following: the connection means 11, 12 of the first connection device 9 on the one hand and the connection means 13, 14 of the second connection device 10 are aligned with one another, so that in the best case the same orientation can result as in the non-pivoted state of the carriage 2, 3 in the Fig. 1 , As a result, a first section 23 of the connecting element 16 and a first section 24 of the connecting element 15 are subjected to less bending stress. In particular, ends of the connecting elements 15, 16, which are attached to the connection means 11, 12, are less bent or kinked at the attachment points. Likewise, second sections 25, 26 are less bent and opposite ends of the connecting elements 15, 16, which are connected to the connecting means 13, 14, are less kinked.

Weiterhin kann durch die Translationsbewegung der ersten Anschlusseinrichtung 9 und der zweiten Anschlusseinrichtung 10 in den Lagern 21 bzw. 22 der Vergrößerung des Abstands zwischen den Anschlusseinrichtungen 9, 10 durch die Drehbewegung um die Z-Achse entgegengewirkt werden und der Abstand wieder verkürzt werden, wodurch die Zugbeanspruchung der Verbindungselemente 15, 16 sinkt.Furthermore, the translational movement of the first connection device 9 and the second connection device 10 in the bearings 21 and 22 counteracts the increase in the distance between the connection devices 9, 10 by the rotary movement about the Z axis and the distance can be shortened again, as a result of which the Tensile stress on the connecting elements 15, 16 decreases.

Fig. 3 zeigt eine Sicht auf den ersten Wagen 2 von hinten entlang der Längsachse X1. In Fig. 3 bedeuten gleiche Bezugszeichen wie in Fig. 1 und Fig. 2 entsprechend gleiche Gegenstände. Fig. 3 shows a view of the first carriage 2 from the rear along the longitudinal axis X1. In Fig. 3 have the same reference numerals as in Fig. 1 and Fig. 2 correspondingly the same objects.

Als wagenbauliche Elemente sind über Fig. 1 und Fig. 2 hinaus noch zwei Seitenwände 30, 31 und ein Drehgestell 32 mit einem Radsatz mit den Rädern 33, 34 in schematischer Art und Weise gezeigt.As wagon building elements are over Fig. 1 and Fig. 2 in addition, two side walls 30, 31 and a bogie 32 with a wheel set with the wheels 33, 34 shown in a schematic manner.

Fig. 3 zeigt zwei Einbaumöglichkeiten für eine Anschlusseinrichtung 9, nämlich einmal im Bereich des Fahrzeugbodens (Fig. 3, unten), was bei Hochflurfahrzeugen vorteilhaft ist, und einmal im Bereich des Daches (Fig. 3, oben), was bei Niederflurfahrzeugen vorteilhaft ist. Es sind für beide Einbausituationen jeweils gleiche Bezugszeichen gewählt und die nachfolgende Figurenbeschreibung kann auf beide Einbausituationen zu lesen sein. Fig. 3 shows two installation options for a connection device 9, namely once in the area of the vehicle floor ( Fig. 3 , below), which is advantageous for high-floor vehicles, and once in the area of the roof ( Fig. 3 , top), which is advantageous for low-floor vehicles. The same reference numerals have been chosen for both installation situations, and the following description of the figures can be read in both installation situations.

Die Gelenkdrehachse Z läuft durch den Gelenkdrehpunkt 35. In Fig. 3 ist das Drehlager 36 dargestellt, mit dem die erste Anschlusseinrichtung 9 drehbeweglich an dem Wagen 2, hier an dem Endgerätquerträger 7, gelagert ist. Das Drehlager 36 weist das Lagerteil 37 auf, das mit der ersten Anschlusseinrichtung 9 drehfest verbunden ist, und das zweite Lagerteil 38. Die Lagerteile 37 und 38 sind gegeneinander um die Drehachse D1 rotierbar.The pivot axis Z runs through the pivot point 35. In Fig. 3 The pivot bearing 36 is shown, with which the first connection device 9 is rotatably mounted on the carriage 2, here on the terminal cross member 7. The rotary bearing 36 has the bearing part 37, which is connected in a rotationally fixed manner to the first connection device 9, and the second bearing part 38. The bearing parts 37 and 38 can be rotated relative to one another about the axis of rotation D1.

Das Drehlager 36 weist weiterhin das Gleitelement 39 auf, das mit dem unteren Lagerteil 38 fest verbunden ist und das in das Gleitlager 21 eingreift und in diesem verschiebbar ist. Somit ist das gesamte Drehlager 36 und damit die damit verbundene erste Anschlusseinrichtung 9 in dem Gleitlager 21 verschiebbar.The pivot bearing 36 also has the sliding element 39 which is fixedly connected to the lower bearing part 38 and which engages in the sliding bearing 21 and is displaceable therein. The entire pivot bearing 36 and thus the associated first connection device 9 can thus be displaced in the slide bearing 21.

In Fig. 3 ist ferner die weitere Drehachse D3 aus Fig. 1 gezeigt, um die das Anschlusselement 9 rotierbar sein kann. Eingesetzt werden kann ein Lager 36, das auch einen Freiheitsgrad in dieser Richtung ermöglicht. Alternativ kann lediglich eine Rotation um die Achse D3 vorgesehen sein und ein entsprechendes Lager vorgesehen sein.In Fig. 3 is also the further axis of rotation D3 Fig. 1 shown, around which the connecting element 9 can be rotated. A bearing 36 can also be used, which also allows a degree of freedom in this direction. Alternatively, only a rotation about the axis D3 can be provided and a corresponding bearing can be provided.

Fig. 4 zeigt eine Draufsicht auf eine weitere Ausführungsform einer erfindungsgemäßen Verbindungsanordnung 40. Gezeigt sind ein erstes Schienenfahrzeugmodul 41 als erstes Schienenfahrzeugelement und ein zweites Modul 42 als zweites Schienenfahrzeugelement. Die Module 41, 42 sind beispielsweise Straßenbahnmodule und durch den Wellenbalg 43 miteinander verbunden. Ferner sind die Module 41, 42 über das schematisch dargestellte Drehgelenk 44 miteinander gekoppelt. Fig. 4 shows a plan view of a further embodiment of a connection arrangement 40 according to the invention. A first rail vehicle module 41 is shown as the first rail vehicle element and a second module 42 as the second rail vehicle element. The modules 41, 42 are, for example, tram modules and are connected to one another by the bellows 43. Furthermore, the modules 41, 42 are coupled to one another via the schematically illustrated swivel joint 44.

Im Endbereich des ersten Moduls 41 sind als erste Anschlusseinrichtungen die Klemmkästen 45, 46 angeordnet, die Klemmkästen für elektrische Leitungen sind. Der Klemmkasten 45 ist für elektrische Leitungen eingerichtet, die elektrischen Strom auf einem ersten Spannungsniveau transportieren, hier bezeichnet mit HV (Hochvolt, Hochspannung). Der Klemmkasten 46 ist für den Anschluss elektrischer Leitungen eingerichtet, die Strom auf einem zweiten Spannungsniveau transportieren, das hier ein Niedrigspannungsniveau ist, nämlich 24 V.In the end region of the first module 41, the terminal boxes 45, 46, which are terminal boxes for electrical lines, are arranged as first connection devices. The terminal box 45 is set up for electrical lines that transport electrical current at a first voltage level, here denoted by HV (high voltage, high voltage). The terminal box 46 is set up for the connection of electrical lines which transport current at a second voltage level, which here is a low voltage level, namely 24 V.

Im Endbereich des zweiten Moduls 42, der dem Endbereich des ersten Moduls 41 benachbart ist, sind als zweite Anschlusseinrichtungen die Klemmkästen 47, 48 angeordnet. Der Klemmkasten 47 ist zur Führung von Verbindungselementen 49 dem Klemmkasten 45 zugeordnet und für das gleiche, erste Spannungsniveau ausgerichtet. Entsprechend ist der Klemmkasten 48 dem Klemmkasten 46 zum Anschluss der Verbindungselemente 50 zugeordnet und für das gleiche, zweite Spannungsniveau ausgelegt.In the end area of the second module 42, which is adjacent to the end area of the first module 41, the terminal boxes 47, 48 are arranged as second connection devices. The terminal box 47 is assigned to the terminal box 45 for guiding connecting elements 49 and is aligned for the same, first voltage level. Correspondingly, the terminal box 48 is assigned to the terminal box 46 for connecting the connecting elements 50 and is designed for the same, second voltage level.

Die Klemmkästen 45, 46, 47, 48 sind drehbar um senkrecht zur Figurenebene stehende und parallel zur Gelenkdrehachse Z ausgerichtete Drehachsen, die hier nicht eingezeichnet sind, aber analog zu einer Drehachse D1 oder D2 aus Fig. 1 und Fig. 2 ausgerichtet und positioniert sein können. Dargestellt sind die Rotationsfreiheitsgrade der Klemmkästen 45, 46, 47, 48 in Form von Doppelpfeilen. Die Klemmkästen sind im Uhrzeigersinn und im Gegenuhrzeigersinn um die erwähnten senkrecht zur Zeichnungsebene stehenden Drehachsen drehbar.The terminal boxes 45, 46, 47, 48 are rotatable about axes of rotation which are perpendicular to the plane of the figure and are oriented parallel to the axis of rotation Z of the axis and which are not shown here, but are analogous to an axis of rotation D1 or D2 Fig. 1 and Fig. 2 can be aligned and positioned. The degrees of freedom of rotation of the terminal boxes 45, 46, 47, 48 are shown in the form of double arrows. The terminal boxes can be rotated clockwise and counterclockwise around the mentioned axes of rotation perpendicular to the plane of the drawing.

Die Verbindungsmittel zwischen den Klemmkästen 45 und 47 sind mehrere Kabel, die ein Kabelbündel bilden und von denen ein Kabel 49 beispielhaft mit Bezugszeichen versehen ist. In analoger Weise ist zwischen den Klemmkästen 46 und 48 ein Bündel aus mehreren Kabeln geführt, von denen eines beispielhaft mit einem Bezugszeichen 50 versehen ist. Die Kabel jedes der Bündel sind mit Bindemitteln 51, 52, 53, 54 zusammengefasst, um eine Bündelung zu erzielen. Dargestellt ist ferner eine Halteeinrichtung aus zwei Gelenkarmen 55, 56, die ein Durchhängen der Kabelbündel in Richtung Gelenk 44 verhindert. Der Gelenkarm 55 ist an dem Modul 42 angelenkt und gelenkig mit dem Gelenkarm 56 verbunden, der mit seinem anderen Ende wiederum gelenkig mit dem Bindemittel oder Haltemittel 51 verbunden ist. Die hier in Fig. 4 dargestellte Haltevorrichtung kann alternativ so ausgebildet sein, wie in EP 2 495 151 A1 beschrieben.The connecting means between the terminal boxes 45 and 47 are a plurality of cables which form a cable bundle and of which a cable 49 is provided with reference numerals by way of example. In an analogous manner, a bundle of several cables is guided between the terminal boxes 46 and 48, one of which is provided with a reference number 50 by way of example. The cables of each of the bundles are combined with binders 51, 52, 53, 54 in order to achieve bundling. Also shown is a holding device made of two articulated arms 55, 56, which prevents the cable bundles from sagging in the direction of articulation 44. The articulated arm 55 is articulated to the module 42 and is articulated to the articulated arm 56, which in turn is articulated to the binder or holding means 51 at its other end. The here in Fig. 4 The holding device shown can alternatively be designed as in EP 2 495 151 A1 described.

In Fig. 4 ist gezeigt, dass die Verbindungsmittel 49 (und weitere) zwischen den Klemmkästen 45 und 47 anders ausgerichtet sind als die Verbindungsmittel 50 (und weitere nicht mit Bezugszeichen bezeichnete) zwischen den Klemmkästen 46 und 48. Endabschnitt des Verbindungsmittels 49 verlassen die Klemmkästen 45 und 47 in Modullängsrichtung X1 bzw. X2. Hingegen sind Endabschnitte des Verbindungsmittels 50, die mit den Klemmkästen 46 und 48 verbunden sind, in Modulquerrichtung Y1 bzw. Y2 aus den Klemmkästen 46, 48 herausgeführt bzw. je nach Betrachtung hineingeführt. Durch die Möglichkeit der Drehung der Klemmkästen 46, 48 kann bei einer Gelenksdrehung um die Z-Achse die relative Ausrichtung der Klemmkästen 46, 48 bzw. der Verlauf der Verbindungsmittel 50 beibehalten oder weitgehend beibehalten werden.In Fig. 4 it is shown that the connecting means 49 (and others) between the terminal boxes 45 and 47 are oriented differently than the connecting means 50 (and others not designated by reference numerals) between the terminal boxes 46 and 48. End section of the connecting means 49 leave the terminal boxes 45 and 47 in FIG Module longitudinal direction X1 or X2. On the other hand, end sections of the connecting means 50, which are connected to the terminal boxes 46 and 48, are led out of the terminal boxes 46, 48 in the module transverse direction Y1 or Y2 or, depending on the consideration, are introduced. Due to the possibility of rotating the terminal boxes 46, 48, the relative orientation of the terminal boxes 46, 48 or the course of the connecting means 50 can be maintained or largely retained in the event of a joint rotation about the Z axis.

Es ist erfindungsgemäß möglich, Verbindungsmittel bzw. Bündel aus Verbindungsmitteln wie in Fig. 4 gezeigt überkreuzt zu verlegen. Beispielsweise ist es möglich, dass ein Bündel Verbindungsmittel sich von einem Klemmkasten 47 zu einem Klemmkasten 46 erstreckt (wobei selbstverständlich dann der Klemmkasten 46 auf dem gleichen Spannungsniveau, HV, betrieben würde). Analog ist eine Führung des Bündels Verbindungsmittel von dem Klemmkasten 48 zu dem Klemmkasten 45 möglich. Allgemein betrachtet würde dann ein Verbindungsmittel von einer ersten Seite eines ersten Schienenfahrzeugteils 41 zu einer zweiten Seite eines zweiten Schienenfahrzeugelements 42 geführt. Als Seite wird hier eine Seite rechts der Längsachse X1 oder X2 definiert oder eine Seite links der Längsachse X1 bzw. X2. Die Begriffe rechts und links sind auf die Fahrtrichtung F bezogen. Eine derartige Verlegung eines Verbindungsmittels von einer Fahrzeugseite zu einer zweiten Fahrzeugseite ist insbesondere vorteilhaft realisierbar, wenn entsprechende Klemmkästen, zwischen denen sich das Verbindungsmittel erstreckt, verschiebbar gelagert sind, wie in Fig. 1 und Fig. 2 anhand der dortigen Ausführungsform beschrieben. Eine derartige Führung eines Verbindungsmittels ist aber auch bereits vorteilhaft realisierbar, wenn die Klemmkästen bzw. allgemeiner die Anschlusseinrichtungen drehbar gelagert sind, wie in Fig. 4 gezeigt. Bereits durch eine drehbare Lagerung ist eine optimale Ausrichtung der Klemmkästen relativ zueinander möglich.It is possible according to the invention to use connecting means or bundles of connecting means as in Fig. 4 shown to lay crossed. For example, it is possible for a bundle of connecting means to extend from a terminal box 47 to a terminal box 46 (the terminal box 46 would of course then be operated at the same voltage level, HV). Analogously, the bundle of connecting means can be guided from the terminal box 48 to the terminal box 45. Generally speaking, a connecting means would then be guided from a first side of a first rail vehicle part 41 to a second side of a second rail vehicle element 42. A side is defined here as a side to the right of the longitudinal axis X1 or X2 or a side to the left of the longitudinal axis X1 or X2. The terms right and left refer to the direction of travel F. Such a laying of a connecting means from one vehicle side to a second side of the vehicle can be realized particularly advantageously if corresponding terminal boxes, between which the connecting means extends, are slidably mounted, as in FIG Fig. 1 and Fig. 2 described using the embodiment there. Such guidance of a connecting means can also already be advantageously realized if the terminal boxes or more generally the connection devices are rotatably mounted, as in FIG Fig. 4 shown. An optimal orientation of the terminal boxes relative to each other is already possible through a rotatable mounting.
