- An inventive bogie for a rail vehicle comprises a frame which is mounted on one or more wheel axles.
- the bogie comprises at least one support surface for a car body.
- On bogie at least one lifting surface is formed, which is formed by a lifting element in its vertical distance from the support surface changeable, so that a spacer element in the vertical distance can be inserted.

- the spacer element can be inserted for permanent increase of a distance between the wheel axle and the entry edge in the vertical distance.
- a lifting element with a lifting surface on the bogie makes it possible to manufacture the lifting element as an integral part of the bogie. To increase the vertical distance are thus no additional devices necessary. It is conceivable that spacer element, which can be inserted in the vertical distance, also to manufacture as an integral part of the bogie. So it is conceivable, for example, to manufacture the spacer element as a rack with backstop. Also conceivable would be an adjustable screw, which is fixable in a preferred position. In particular, it is also conceivable to provide spacer elements which are mutually rotatable so that they have different thicknesses by turning.

- the support element 30 has a support surface 31 in its upper region.
- the support surface 31 is spaced from the lower edge of the wheels 101, and thus of the rail upper edge SOK, with the distance Z.
- the bearing surface 31 correlates in the factory state, for example, with an entry edge of a platform. If the wheels 101 are over-turned, ie reduced in diameter, a desired dimension between the support surface 31 and the platform changes. This needs to be corrected.
- FIG. 2 shows a perspective view of the bogie 100 from FIG. 1 , For clarity, only individual elements of a group of the same elements are provided with a reference numeral.
- the bogie 100 has four wheels 101, which are each arranged in pairs on a wheel axle 20.
- the wheel axles 20 are arranged on a frame 10, on which in turn a support element 30 is arranged as a traverse.
- the support member 30 is connected to here unspecified resilient elements with the frame 10, which in turn is connected to the wheel axles 20 with resilient elements.

- This fluid pushes the lifting element 50 upwards (see FIG. 3b ). If the lower edge of the lifting element 50 reaches the seal 63, the sealing function between the seal 62 and the lifting element 50 is interrupted. The fluid pumped in via the coupling element 64 can escape around the cylindrical lifting element 50 via an annular gap. Further movement of the lifting element 50 upwards is therefore no longer possible.

Description
Die vorliegende Erfindung betrifft ein Drehgestell für ein Schienenfahrzeug, ein Verfahren zum Kompensieren von Durchmesserveränderungen von Rädern von Schienenfahrzeugen sowie ein Schienenfahrzeug mit einer entsprechenden Vorrichtung gemäss den Oberbegriffen der unabhängigen Ansprüche.The present invention relates to a bogie for a rail vehicle, a method for compensating for changes in the diameter of wheels of rail vehicles and a rail vehicle with a corresponding device according to the preambles of the independent claims.
Typischerweise weisen Schienenfahrzeuge Räder aus Metall auf, welche auf Schienen aus Metall laufen. Im Verlaufe des Gebrauchs nutzen die Räder ab. Das heisst, sie weisen Verschleiss auf. Somit müssen die Räder nach längerer Betriebszeit überdreht werden. Das Überdrehen der Räder geht einher mit einer Durchmesseränderung der Räder. Typischerweise sind die Räder auf Achswellen montiert, welche federnd an einem Rahmen befestigt sind, der wiederum federnd mit einem Wagenkasten des Schienenfahrzeugs verbunden ist. Eine Änderung des Durchmessers der Räder hat demnach zur Folge, dass die Einstiegskanten der Wagenkästen gegenüber einer festgelegten Höhe, beispielsweise eines Bahnsteiges, nach dem Überdrehen der Räder eine Differenz aufweisen. Diese Differenz muss korrigiert werden.Typically, rail vehicles have metal wheels running on rails of metal. In the course of use, use the wheels off. That means, they wear out. Thus, the wheels must be overrun after a long period of operation. The over-turning of the wheels is accompanied by a change in the diameter of the wheels. Typically, the wheels are mounted on axle shafts, which are resiliently mounted to a frame, which in turn is resiliently connected to a car body of the rail vehicle. A change in the diameter of the wheels has the consequence that the entry edges of the car bodies with respect to a fixed height, for example, a platform, after over-turning of the wheels have a difference. This difference needs to be corrected.
Aus dem Stand der Technik sind verschiedene Vorrichtungen und Verfahren bekannt, um diese Höhendifferenz wieder auszugleichen. Typischerweise werden die Schienenfahrzeuge in grosse Einstellhallen von Unterhaltswerkstätten gebracht, wobei die kompletten Schienenfahrzeuge an ihren Wagenkästen angehoben werden, um die darunterliegenden Drehgestelle zu entlasten. Im Anschluss werden die Befestigungen der Drehstelle gelöst, sodass an einer Schnittstelle zwischen Drehgestell und Wagenkasten ein Distanzelement eingefügt werden kann. Die Drehgestelle werden im Anschluss wieder verschraubt und die Schienenfahrzeuge wieder auf die Schiene gestellt. Durch den Einschub von Distanzelementen sind die Einstiegskanten der Wagenkästen entsprechend weiter von der Radachse beabstandet, so dass die ursprüngliche Höhe der Einstiegskanten auch mit abgenutzten Rädern wieder hergestellt ist.Various devices and methods are known from the prior art to compensate for this height difference again. Typically, the rail vehicles are brought into large garages of maintenance workshops, the entire rail vehicles are raised to their car bodies to relieve the underlying bogies. Afterwards, the fixings of the turning point are loosened so that a spacer element can be inserted at an interface between bogie and car body. The bogies are in the Screwed back connection and put the rail vehicles back on the rail. As a result of the insertion of spacer elements, the entry edges of the carriage bodies are spaced further apart from the wheel axle, so that the original height of the entry edges is restored even with worn wheels.
Mit der
Die bekannten Vorrichtungen und Verfahren aus dem Stand der Technik weisen unterschiedliche Nachteile auf. So müssen einerseits entweder sehr grosse Werkstätten oder Instandhaltungshallen zur Verfügung gestellt werden, oder das Verstellen der Distanzscheiben benötigt zusätzliche Vorrichtungen oder Werkzeug.The known devices and methods of the prior art have different disadvantages. Thus, on the one hand either very large workshops or maintenance halls must be made available, or the adjustment of the spacers requires additional devices or tools.
Es ist Aufgabe der Erfindung, diese und weitere Nachteile des Standes der Technik zu beheben. Insbesondere soll eine Vorrichtung und ein Verfahren bereitgestellt werden, welche es ermöglicht, Durchmesseränderungen an Rädern von Schienenfahrzeugen auf einfache Art zu kompensieren.It is an object of the invention to overcome these and other disadvantages of the prior art. In particular, a device and a method are to be provided, which makes it possible to compensate for changes in diameter of wheels of rail vehicles in a simple way.
Diese Aufgabe wird durch die in den unabhängigen Patentansprüchen definierten Vorrichtungen und Verfahren gelöst. Weitere Ausführungsformen ergeben sich aus den abhängigen Patentansprüchen.This object is achieved by the devices and methods defined in the independent patent claims. Further embodiments emerge from the dependent claims.
Ein erfindungsgemässes Drehgestell für ein Schienenfahrzeug umfasst einen Rahmen, der auf einer oder mehreren Radachsen gelagert ist. Das Drehgestell umfasst wenigstens eine Auflagefläche für einen Wagenkasten. Am Drehgestell ist zumindest eine Hubfläche ausgebildet, die durch ein Hubelement in ihrem vertikalen Abstand von der Auflagefläche veränderbar ausgebildet ist, sodass ein Distanzelement in den vertikalen Abstand einlegbar ist. Zusätzlich oder alternativ ist der vertikale Abstand mittels des Hubelements fixierbar.An inventive bogie for a rail vehicle comprises a frame which is mounted on one or more wheel axles. The bogie comprises at least one support surface for a car body. On bogie at least one lifting surface is formed, which is formed by a lifting element in its vertical distance from the support surface changeable, so that a spacer element in the vertical distance can be inserted. Additionally or alternatively, the vertical distance can be fixed by means of the lifting element.
Eine Auflagefläche des Drehgestells kann beispielsweise an einer Traverse des Drehgestells angeordnet sein. Eine Anordnung an einem Teller oberhalb einer Luftfederung ist ebenfalls vorstellbar.A bearing surface of the bogie can be arranged, for example, on a traverse of the bogie. An arrangement on a plate above an air suspension is also conceivable.
Die Hubfläche des Hubelementes weist zumindest in einem angehobenen Zustand einen vertikalen Abstand zur Auflagefläche auf. Dabei ist es vorstellbar, dass Hubfläche und Auflagefläche horizontal beabstandet sind und/oder an unterschiedlichen Elementen des Drehgestells angeordnet sind.The lifting surface of the lifting element has, at least in a raised state, a vertical distance to the support surface. It is conceivable that the lifting surface and support surface are spaced horizontally and / or are arranged on different elements of the bogie.
Das Distanzelement ist zur dauerhaften Erhöhung eines Abstandes zwischen Radachse und Einstiegskante in den vertikalen Abstand einlegbar.The spacer element can be inserted for permanent increase of a distance between the wheel axle and the entry edge in the vertical distance.
Ein Hubelement mit einer Hubfläche am Drehgestell ermöglicht es, das Hubelement als integralen Bestandteil des Drehgestelles zu fertigen. Zur Erhöhung des vertikalen Abstandes sind somit keine zusätzlichen Vorrichtungen notwendig. Dabei ist es vorstellbar, dass Distanzelement, welches in den vertikalen Abstand einlegbar ist, ebenfalls als integralen Bestandteil des Drehgestells zu fertigen. So ist es beispielsweise vorstellbar, das Distanzelement als Zahnstange mit Rücklaufsperre zu fertigen. Ebenfalls vorstellbar wäre eine verstellbare Stellschraube, welche in einer bevorzugten Position fixierbar ist. Insbesondere ist es aber auch vorstellbar, Distanzelemente vorzusehen, welche gegeneinander so verdrehbar sind, dass sie durch Verdrehen unterschiedliche Dicken aufweisen.A lifting element with a lifting surface on the bogie makes it possible to manufacture the lifting element as an integral part of the bogie. To increase the vertical distance are thus no additional devices necessary. It is conceivable that spacer element, which can be inserted in the vertical distance, also to manufacture as an integral part of the bogie. So it is conceivable, for example, to manufacture the spacer element as a rack with backstop. Also conceivable would be an adjustable screw, which is fixable in a preferred position. In particular, it is also conceivable to provide spacer elements which are mutually rotatable so that they have different thicknesses by turning.
Vorzugsweise ist das Hubelement am Drehgestell integral angeordnet. Das Hubelement ist somit als Teil des Drehgestells ausgebildet und/oder zumindest dauerhaft befestigt.Preferably, the lifting element is integrally arranged on the bogie. The lifting element is thus formed as part of the bogie and / or at least permanently attached.
Somit sind sämtliche Vorrichtung und/oder Mechanismen zur Erhöhung des vertikalen Abstandes zwischen Hubfläche und Auflagefläche am Drehgestell angeordnet. Dies ermöglicht es, auf aufwendige und komplizierte Werkstätten und/oder Werkstatteinrichtungen zu verzichten.Thus, all device and / or mechanisms for increasing the vertical distance between the lifting surface and the support surface are arranged on the bogie. This makes it possible to dispense with complex and complicated workshops and / or workshop equipment.
Vorzugsweise ist das Hubelement hydraulisch oder pneumatisch betätigbar.Preferably, the lifting element is hydraulically or pneumatically actuated.
Typischerweise weisen Schienenfahrzeuge Einrichtungen und/oder Kreisläufe auf, welche pneumatisch und teilweise auch hydraulisch betätigt sind. Somit ist es möglich, das Hubelement unabhängig von externen Vorrichtungen oder Antrieben zu betätigen.Typically, rail vehicles on facilities and / or circuits, which are pneumatically and partially hydraulically operated. Thus, it is possible to operate the lifting element independently of external devices or drives.
Eine derartige Ausgestaltung beschränkt jedoch das Betätigen des Hubelements nicht auf die Autonomie eines Schienenfahrzeuges. Externe Antriebe oder externes Zurverfügungstellen von Pneumatik oder Hydraulik ist möglich.However, such a configuration does not limit the actuation of the lifting element on the autonomy of a rail vehicle. External drives or external provision of pneumatics or hydraulics is possible.
Vorzugsweise weist das Drehgestell eine Traverse auf, welche mindestens eine Bohrung zur beweglichen Aufnahme des Hubelementes aufweist, so dass die Bohrung und das Hubelement einen mit einem Fluid befüllbaren Raum bilden.Preferably, the bogie has a traverse, which has at least one bore for movably receiving the lifting element, so that the bore and the lifting element form a space that can be filled with a fluid.
Eine platzsparende Integration des Hubelementes am Drehgestell ist damit ermöglicht.A space-saving integration of the lifting element on the bogie is thus possible.
Vorzugsweise weist die Bohrung einen Fluidzufuhrkanal auf, welcher vorzugsweise ein Kupplungselement zum Anschluss einer Fluidquelle, insbesondere Druckluft oder Hydrauliköl aufweist.Preferably, the bore has a fluid supply channel, which preferably has a coupling element for connecting a fluid source, in particular compressed air or hydraulic oil.
Das ermöglicht das Zu- oder Abkoppeln der Fluidquelle, so dass beispielsweise im normalen Betrieb des Schienenfahrzeuges das Hubelement entkoppelt ist. Eine Fehlmanipulation des Hubelementes ist damit verunmöglicht.This makes it possible to connect or disconnect the fluid source, so that, for example, during normal operation of the rail vehicle, the lifting element is decoupled. A faulty manipulation of the lifting element is thus impossible.
Die Bohrung und/oder das Hubelement kann zumindest ein Dichtelement aufweisen.The bore and / or the lifting element may have at least one sealing element.
Dadurch ist gewährleistet, dass innerhalb der Bohrung ein entsprechender Druckaufbau möglich ist. Ausserdem ist das Eindringen von Schmutz oder Verunreinigungen verhindert.This ensures that within the bore a corresponding pressure build-up is possible. In addition, the penetration of dirt or impurities is prevented.
Vorzugsweise ist das Dichtelement derart angeordnet, dass eine Dichtwirkung nur bis zu einer festgelegten Hubhöhe des Hubelementes erzielbar ist.Preferably, the sealing element is arranged such that a sealing effect can only be achieved up to a fixed lifting height of the lifting element.
Dies gewährleistet, dass das Hubelement nur bis zu einem bestimmten Grad bewegt wird. Ein Verschieben des Hubelementes über das Dichtelement bedeutet, dass die Kombination aus Bohrung und Hubelement undicht wird und Druck abfällt. Eine weitere Verschiebung des Hubelementes ist damit verunmöglicht.This ensures that the lifting element is moved only to a certain degree. A displacement of the lifting element Over the sealing element means that the combination of bore and lifting element is leaking and pressure drops. Further displacement of the lifting element is thus impossible.
Am Hubelement kann ein Rückstellmechanismus vorgesehen sein, welcher vorzugsweise als eine Rückstellfeder zum Rückstellen des Hubelementes ausgebildet ist.On the lifting element may be provided a return mechanism, which is preferably designed as a return spring for returning the lifting element.
Vorzugsweise ist eine Hubfläche des Hubelementes in Wirkverbindung mit einem Wagenkasten oder einem Gegenstück einer Schnittstelle. Nach dem Anheben des Wagenkastens und nach dem Einlegen des Distanzstückes soll das Hubelement aber wieder in Richtung Ausgangslage bewegt werden um falsch eingeleitete Kräfte zu vermeiden. Ein Zurückbewegen des Hubelementes kann ausserdem vorteilhaft in Bezug auf den Schutz vor Eindringen von Schmutz oder Feuchtigkeit sein.Preferably, a lifting surface of the lifting element is in operative connection with a car body or a counterpart of an interface. After lifting the car body and after inserting the spacer but the lifting element is to be moved back towards the starting position to avoid incorrectly initiated forces. A backward movement of the lifting element may also be advantageous in terms of protection against ingress of dirt or moisture.
Dies wird durch einen wie vorliegend beschriebenen Rückstellmechanismus ermöglicht. Alternativ kann das Gewicht des aufliegenden Wagenkastens als Rückstellkraft nach Einlegen des Distanzstückes verwendbar sein.This is made possible by a return mechanism as described herein. Alternatively, the weight of the resting car body can be used as a restoring force after inserting the spacer.
Das Drehgestell kann einen oder mehrere, vorzugsweise zwei Zentrierbolzen zum Zentrieren eines Wagenkastens auf dem Drehgestell aufweisen, welche als Hubelemente ausgebildet sind. Eine Oberfläche des Zentrierbolzens kann als Hubfläche ausgebildet sein.The bogie may have one or more, preferably two centering bolts for centering a car body on the bogie, which are designed as lifting elements. A surface of the centering pin can be designed as a lifting surface.
Somit kann das Hubelement eine zweite Funktion übernehmen. Insbesondere ist es damit möglich, bereits bestehende Zentrierbolzen am Drehgestell als Hubelemente auszubilden und diesen somit eine zweite Funktion verleihen. Dies ermöglicht den Verzicht auf weitere zusätzliche Teile zum Verstellen des vertikalen Abstandes.Thus, the lifting element can take over a second function. In particular, it is thus possible to form existing centering bolts on the bogie as lifting elements and thus give them a second function. This allows the Waiver of additional parts to adjust the vertical distance.
Es ist ebenfalls vorstellbar, dass eine oder mehrere Luftfedern einer Luftfederung zwischen dem Rahmen und der Auflagefläche des Drehgestells als Hubelemente ausgebildet sind. Zumindest einer ersten Luftfeder bevorzugt zwei ersten Luftfedern ist je eine Hubfläche zugeordnet und einer zweiten Luftfeder, vorzugsweise zwei Luftfedern ist je eine Auflagefläche zugeordnet. Die erste oder die ersten Luftfedern sind unter einem ersten Wagenkasten anordenbar und die zweite oder die zweiten Luftfedern sind unter einem zweiten Wagenkasten anordenbar.It is also conceivable that one or more air springs of an air suspension between the frame and the support surface of the bogie are designed as lifting elements. At least one first air spring, preferably two first air springs, are each assigned one lifting surface, and a second air spring, preferably two air springs, are each assigned one bearing surface. The first or the first air springs can be arranged under a first car body and the second or the second air springs can be arranged under a second car body.
Dies ermöglicht das Nutzen bereits bestehender Luftfederelemente als Hubelemente. Ein Verstellen des vertikalen Abstandes zwischen einer Hubfläche und einer Auflagefläche eines ersten Wagenkastens wird durch das Anheben eines zweiten Wagenkastens ermöglicht. Die Wagenkästen sind hier untereinander verbunden.This allows the use of existing air spring elements as lifting elements. An adjustment of the vertical distance between a lifting surface and a support surface of a first car body is made possible by lifting a second car body. The car bodies are interconnected here.
Die ersten Luftfedern und die zweiten Luftfedern sind je einer Gruppe von Luftfedern zugeordnet. Vorzugsweise sind zwischen den einzelnen Gruppen von Luftfedern einer Luftfederung Absperrmittel zum Trennen der Gruppen von Luftfedern voneinander vorgesehen.The first air springs and the second air springs are each assigned to a group of air springs. Preferably, shut-off means for separating the groups of air springs from each other are provided between the individual groups of air springs of an air suspension.
Dies ermöglicht das selbstständige und unabhängige Betätigen der einzelnen Gruppen und/oder von einzelnen Luftfedern untereinander.This allows the independent and independent actuation of the individual groups and / or individual air springs with each other.
Ein Wagenkasten kann somit unabhängig von einem anderen Wagenkasten angehoben werden.A car body can thus be lifted independently of another car body.
Dies ist vor allem bei Schienenfahrzeugenkonfigurationen mit sogenannten Jakobs-Drehgestellen, auf die jeweils zwei benachbarte Wagenkastenenden abgestützt werden, vorteilhaft. Typischerweise sind benachbarte Wagenkastenenden mittels einer Kupplung miteinander verbunden.This is particularly advantageous in rail vehicle configurations with so-called Jakobs bogies, on each of which two adjacent car body ends are supported. Typically, adjacent carbody ends are interconnected by means of a coupling.
Das Anheben eines Wagenkastens mittels der zugehörigen Luftfedergruppe erlaubt das gleichzeitige Anheben des benachbarten mit dem ersten Wagenkasten verbundenen zweiten Wagenkastenendes. Dabei sind lediglich die Luftfedern unter dem ersten Wagenkasten mit Druck beaufschlagt und die Luftfedern unterhalb des zweiten Wagenkasten weisen einen geringeren Druck auf als die Luftfedern unter dem ersten Wagenkasten. Vorzugsweise sind sie drucklos. Somit kann der der zweite Wagenkasten mit Distanzelementen beabstandet werden.The lifting of a car body by means of the associated air spring group allows the simultaneous lifting of the adjacent connected to the first car body second car body end. Only the air springs under the first car body are pressurized and the air springs below the second car body have a lower pressure than the air springs under the first car body. Preferably, they are depressurized. Thus, the second car body can be spaced with spacers.
Die Beaufschlagung der Luftfedern kann vorzugsweise über ein auf dem Schienenfahrzug für den Betrieb der Luftfederung bereits vorhandenes Druckluftsystem erfolgen.The admission of the air springs can preferably take place via a compressed air system already present on the rail vehicle for the operation of the air suspension.
Die Luftfederung weist vorzugsweise ein Kupplungselement zum Anschluss an eine externe Druckluftquelle auf. Vorzugsweise weisen die einzelnen Gruppen von Luftfedern separate Kupplungselemente auf.The air suspension preferably has a coupling element for connection to an external compressed air source. Preferably, the individual groups of air springs have separate coupling elements.
Das Drehgestell kann als Jakobsdrehgestell ausgebildet sein.The bogie can be designed as a Jacob bogie.
Eine unkomplizierte und einfache Erhöhung des vertikalen Abstandes an Schienenfahrzeugen mit Jakobsdrehgestell ist dadurch ermöglicht.An uncomplicated and easy increase of the vertical distance on rail vehicles with Jakobs bogie is thereby made possible.
Ein Distanzelement des Drehgestells kann mehrteilig aufgebaut sein und in seiner Dicke variabel ausgebildet sein. Die Dicke ist vorzugsweise durch Verdrehen einzelner Elemente des Distanzelementes gegeneinander einstellbar.A spacer element of the bogie may be constructed in several parts and be variable in its thickness. The fat is preferably adjustable by rotating individual elements of the spacer element against each other.
Dies ermöglicht es, das Distanzelement in einer ersten Lage und damit mit einer ersten Dicke am Drehgestell anzuordnen. Zusätzliche Bauteile sind zur Erhöhung des vertikalen Abstandes damit überflüssig.This makes it possible to arrange the spacer element in a first position and thus with a first thickness on the bogie. Additional components are unnecessary to increase the vertical distance.
Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zum Kompensieren von Durchmesserveränderungen von Rädern von Schienenfahrzeugen, vorzugsweise mit einem Drehgestell wie vorgängig beschrieben. Ein Distanzelement wird in eine vertikalen Abstand zwischen einer Hubfläche und einer Auflagefläche eingelegt, wobei der vertikale Abstand der Hubfläche zur Auflagefläche mit einem Hubelement verändert und insbesondere vergrössert wird, wobei das Hubelement vom Drehgestell umfasst ist. Das Distanzelement wird zur dauerhaften Beabstandung der Hubfläche zur Auflagefläche eingelegt, derart, dass eine Höhe zwischen der Radachse und einer Einstiegskante des Schienenfahrzeuges dauerhaft vergrössert wird.Another aspect of the invention relates to a method for compensating for changes in the diameter of wheels of rail vehicles, preferably with a bogie as described above. A spacer element is inserted into a vertical distance between a lifting surface and a support surface, wherein the vertical distance of the lifting surface is changed to the support surface with a lifting element and in particular increased, wherein the lifting element is included in the bogie. The spacer is inserted for permanent spacing of the lifting surface to the support surface, such that a height between the wheel axle and an entry edge of the rail vehicle is permanently increased.
Dies ermöglicht es, dass nach dem Vergrössern des Abstandes keine weiteren Massnahmen notwendig sind, insbesondere ist es nicht notwendig, ein Hubelement welches beispielsweise zusätzlich angebracht wurde, wieder zu entfernen um das Drehgestell in einen Betriebszustand zu bringen.This makes it possible that after enlarging the distance, no further measures are necessary, in particular, it is not necessary to remove a lifting element which, for example, was additionally attached to bring the bogie in an operating condition.
Vorzugsweise wird der Abstand mit einem integral am Drehgestell angeordneten Hubelement verändert. Die Vorteile eines integral am Drehgestell ausgeführten/angeordneten Elementes sind vorliegend erwähnt.Preferably, the distance is changed with an integrally arranged on the bogie lifting element. The advantages of an integrally formed on the bogie / arranged element are mentioned herein.
Das Hubelement kann in einer Bohrung aufgenommen sein und mit dieser einen Hohlraum bilden, wobei dieser Hohlraum mit einem Fluid und insbesondere Druckluft oder Hydrauliköl beaufschlagt wird, so dass das Hubelement unter Druck bewegt wird und somit der vertikale Abstand der Hubfläche von der Auflagefläche verändert wird.The lifting element can be accommodated in a bore and form a cavity with it, wherein this cavity is acted upon by a fluid and in particular compressed air or hydraulic oil, so that the lifting element is moved under pressure and thus the vertical distance of the lifting surface is changed by the support surface.
Ein einfaches Verändern des vertikalen Abstandes ist dadurch ermöglicht.A simple change of the vertical distance is made possible.
Zur Beibehaltung eines grösseren Abstandes zwischen der Auflagefläche und der Radachse des Drehgestells wird vorzugsweise ein Distanzelement auf eine gewünschte Dicke eingestellt.To maintain a greater distance between the support surface and the wheel axle of the bogie, a spacer element is preferably set to a desired thickness.
Dies ermöglicht das Verwenden eines Distanzelementes, welches bereits vor dem Vergrössern des Abstandes als Bestandteil des Drehgestells ausgebildet ist.This allows the use of a spacer, which is already formed before the enlargement of the distance as part of the bogie.
Vorzugsweise wird die Dicke des Distanzelementes durch Verdrehen einzelner Elemente des Distanzelementes gegeneinander eingestellt.Preferably, the thickness of the spacer element is adjusted by rotating individual elements of the spacer element against each other.
Das Distanzelement kann somit aus mehreren zueinander komplementären Elementen gefertigt sein.The spacer element can thus be made of a plurality of mutually complementary elements.
Nach dem Vergrössern des vertikalen Abstandes kann das Hubelement drucklos gemacht werden, insbesondere durch Ablassen oder Entlasten des Fluides. Vorzugsweise wird das Hubelement mit einem Rückstellelement in eine Ausgangslage zurück gebracht.After increasing the vertical distance, the lifting element can be depressurized, in particular by draining or relieving the fluid. Preferably, the lifting element is brought back with a return element in an initial position.
Alle Elemente können somit wieder in ihre Ausgangslage gebracht werden. Ein unbeabsichtigtes Einbringen von Kräften und / oder eine Beeinträchtigung der Funktion durch Umgebungseinflüsse wie Schmutz oder Wasser ist damit verhindert.All elements can thus be returned to their original position. An unintentional introduction of forces and / or an impairment of the function by environmental influences such as dirt or water is prevented.
Ein weiterer Aspekt der Erfindung betrifft ein Schienenfahrzeug mit einem wie vorliegend beschriebenem Drehgestell, vorzugsweise umfassend insbesondere einen Wagenkasten. Das Vorkonvektionieren und damit das Abstimmen aller Komponenten aufeinander, insbesondere des Hubelementes und des kompletten Schienenfahrzeuges ist damit ermöglicht.Another aspect of the invention relates to a rail vehicle with a bogie as described herein, preferably comprising in particular a car body. The pre-convection and thus the tuning of all components to each other, in particular the lifting element and the complete rail vehicle is thus made possible.
Ein weiterer Aspekt der Vorrichtung betrifft ein Schienenfahrzeug mit einem Wagenkasten und einem Drehgestell wie vorliegend beschrieben. Dabei ist das Hubelement integral am Wagenkasten angeordnet. Vorzugsweise weist der Wagenkasten eine Bohrung zur beweglichen Aufnahme des Hubelementes auf, so dass die Bohrung und das Hubelement einen mit einem Fluid befüllbaren Raum bilden.Another aspect of the device relates to a rail vehicle with a car body and a bogie as described herein. The lifting element is integrally arranged on the car body. Preferably, the car body has a bore for movably receiving the lifting element, so that the bore and the lifting element form a space that can be filled with a fluid.
Dies ermöglicht das integrale Fertigen des Hubelementes am Wagenkasten, unabhängig, wie das zugehörige Drehgestell ausgebildet ist.This allows the integral manufacture of the lifting element on the car body, regardless of how the associated bogie is formed.
