Description

Die Erfindung betrifft einen Zugverband mit mindestens einer Aufhängungsvorrichtung, an der mindestens ein Hochspannungskabelabschnitt aufgehängt ist.The invention relates to a train assembly with at least one suspension device on which at least one high-voltage cable section is suspended.

In Bereich der Schienenfahrzeugtechnik ist es bekannt, dass ein Zugverband zwei Stromabnehmer aufweisen kann. Diese können jeweils an einem Endwagen des Zugverbandes angeordnet sein. Aus Gründen der Redundanz verbindet dann eine Hochspannungsleitung die beiden Stromabnehmer mittels Hochspannungsleitungen und sog. Jumpern, d.h. Kabelbrücken zwischen den Wagenübergängen. Die Hochspannungsleitung verläuft auch über Trennschalter und Haupttransformatoren.In the field of rail vehicle technology, it is known that a train set can have two pantographs. These can each be arranged on an end car of the train set. For reasons of redundancy, a high-voltage line then connects the two current collectors by means of high-voltage lines and so-called jumpers, i.e. Cable bridges between the car crossings. The high-voltage line also runs over isolating switches and main transformers.

Die Druckschrift EP 1 415 883 B1 beschreibt einen Verbindungskasten, an den elektrische Kabel angeschlossen werden. Im Innern des Verbindungskastens sind elektrische Leitungen untergebracht, die beidseitig an den Verbindungskasten angeschlossene elektrische Kabel mit einander verbinden. Der Verbindungskasten ist an einer Zwischenkupplung eines Zugverbands angebracht. Nachteilig ist hierbei, dass der Bauaufwand und das Gewicht sehr hoch sind. Außerdem ergeben sich bei den Kabeln außerhalb des Verbindungskastens ungünstige Biegeradien im Bereich der Anschlüsse am Verbindungskasten, wenn der Zugverband durch Kurven fährt. Dadurch kann ein Kabelverschleiß im Bereich der Anschlüsse am Verbindungskasten entstehen.The publication EP 1 415 883 B1 describes a junction box to which electrical cables are connected. Inside the junction box there are electrical cables that connect electrical cables connected to the junction box on both sides. The junction box is attached to an intermediate coupling of a train set. The disadvantage here is that the construction effort and weight are very high. In addition, the cables outside the junction box have unfavorable bending radii in the area of the connections on the junction box when the train set is cornering. This can result in cable wear in the area of the connections on the connection box.

Die Druckschrift FR 2 713 183 B1 offenbart einen Zugverband, bei dem ein Kabelübergang für Hochspannungsleitungen im Dachbereich zwischen zwei Wagen angeordnet ist. Der Kabelübergang ist an einer Teleskopstange befestigt. Bei Kurvenfahrten verkürzt bzw. verlängert sich die Teleskopstange. Auch hier ist nachteilig, dass ein hoher Bauaufwand erforderlich ist. Außerdem ergibt sich ein Verschleiß in der Teleskopstange.The publication FR 2 713 183 B1 discloses a train set in which a cable transition for high-voltage lines is arranged in the roof area between two cars. The cable transition is attached to a telescopic rod. The telescopic rod shortens or lengthens when cornering. It is also disadvantageous here that a high level of construction is required. There is also wear in the telescopic rod.

Ein ähnlicher Zugverband ist auch von der Druckschrift DE 31 26 095 A1 , die eine Leitungshalterung für Leitungen beschreibt, die vom vorderen zum hinteren Fahrzeugteil eines zwei um eine senkrechte Achse drehbar miteinander verbundene Fahrzeugteile umfassenden Gelenkfahrzeuges führen, bekannt.A similar train set is also from the publication DE 31 26 095 A1 , which describes a line holder for lines leading from the front to the rear vehicle part of an articulated vehicle comprising two vehicle parts rotatably connected about a vertical axis.

Die Druckschrift JP 2602968 Y betrifft eine Kabelverbindung zwischen zwei Wagen eines Zugverbands. Die Kabelverbindung kann im Dachbereich oder im Untergestellbereich angeordnet sein. Bei einer Anordnung im Untergestellbereich liegt die Kabelverbindung auf einer Rolle auf, die an einem der beiden Wagen befestigt ist. Nachteilig ist hier, dass bei einer Anlagerung von Schmutz, Eis, Sand oder Ähnlichem zwischen der Rolle und der Kabelverbindung eine Materialschädigung an der Kabelverbindung erfolgen kann. Bei elektrischen Kabeln kann dies zu Gefahrensituationen führen.The publication JP 2602968 Y relates to a cable connection between two carriages of a train association. The cable connection can be arranged in the roof area or in the base area. In the case of an arrangement in the underframe area, the cable connection rests on a roller which is attached to one of the two carriages. The disadvantage here is that with an accumulation of Dirt, ice, sand or the like between the reel and the cable connection can damage the material of the cable connection. With electrical cables this can lead to dangerous situations.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen Zugverband zu schaffen, bei dem eine Hochspannungskabelverbindung zwischen zwei Wagen aufgehängt ist, wobei die Hochspannungskabelverbindung in Kurven günstige Biegeradien aufweist, ein geringer Bauaufwand erforderlich ist und ein Verschleiß vermieden wird.The invention is therefore based on the object of providing a train assembly in which a high-voltage cable connection is suspended between two carriages, the high-voltage cable connection having favorable bending radii in curves, requiring little construction and wear and tear being avoided.

Diese Aufgabe wird erfindungsgemäß mit einem Zugverband mit mindestens einer Aufhängungsvorrichtung nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.This object is achieved according to the invention with a train assembly with at least one suspension device according to claim 1. Advantageous embodiments of the invention are contained in the subclaims.

Erfindungsgemäß besteht die Lösung der Aufgabe in einem Zugverband mit mindestens einer Aufhängungsvorrichtung, an der mindestens ein Hochspannungskabelabschnitt aufgehängt ist, wobei der Zugverband mindestens zwei Wagen aufweist und die Aufhängungsvorrichtung den Hochspannungskabelabschnitt jeweils zwischen zwei benachbarten Wagen des Zugverbands aufnimmt und wobei jeder Hochspannungskabelabschnitt zwei Enden aufweist, die jeweils über eine Steckverbindung mit einer jeweils zugehörigen Hochspannungsleitung in einem jeweils zugehörigen Wagen verbunden sind, wobei die Aufhängungsvorrichtung an einer mechanischen Zwischenkupplung zwischen den zwei Wagen befestigt ist. Der gesamte Hochspannungskabelabschnitt ist biegsam und ist an der Aufhängungsvorrichtung beweglich und elastisch gelagert.According to the invention, the object is achieved in a train set with at least one suspension device on which at least one high-voltage cable section is suspended, the train set having at least two carriages and the suspension device receiving the high-voltage cable section in each case between two adjacent carriages of the train set, and wherein each high-voltage cable section has two ends, which are each connected via a plug connection to a respectively associated high-voltage line in a respectively associated carriage, the suspension device being fastened to a mechanical intermediate coupling between the two carriages. The entire high-voltage cable section is flexible and is movably and elastically supported on the suspension device.

Ein Vorteil besteht darin, dass eine Biegsamkeit des Hochspannungskabelabschnitts und eine bewegliche und elastische bzw. federnde bzw. nachgiebige Lagerung günstige Biegeradien am Hochspannungskabelabschnitt und damit ein günstiges Biegeverhalten des gesamten Hochspannungskabelabschnitts gewährleisten, z.B. wenn der Zugverband durch Kurven fährt und/oder bei einem Wechsel zwischen einer gestauchten Position und einer Normalposition. Auch wenn sich die Zwischenkupplung in der gestauchten Position oder der Normalposition befindet, sind die Biegeradien am Hochspannungskabelabschnitt günstig. Die Zwischenkupplung kann z.B. eine automatische Kupplung oder eine Permanentkupplung sein. Durch die bewegliche und elastische Lagerung bzw. Aufhängung kann sich der Hochspannungskabelabschnitt an der Aufhängungsvorrichtung jeder Bewegung der Zwischenkupplung und der beiden Wagen anpassen. Außerdem wird ein Verschleiß am Hochspannungskabelabschnitt vermieden.One advantage is that a flexibility of the high-voltage cable section and a movable and elastic or resilient or resilient mounting ensure favorable bending radii on the high-voltage cable section and thus a favorable bending behavior of the entire high-voltage cable section, for example when the train structure is traveling through curves and / or when changing between a compressed position and a normal position. Even if the intermediate coupling is in the compressed position or the normal position, the bending radii on the high-voltage cable section are favorable. The intermediate clutch can be, for example, an automatic clutch or a permanent clutch. Due to the movable and elastic mounting or suspension, the high-voltage cable section adapt to the suspension device of every movement of the intermediate coupling and the two carriages. Wear on the high-voltage cable section is also avoided.

In einer vorteilhaften Weiterbildung der Erfindung weisen die zwei Enden des Hochspannungskabelabschnitts Steckerelemente auf, wobei die Steckerelemente jeweils in ein zugehöriges Steckdosenelement an einem jeweils zugehörigen Wagen einsteckbar sind, und jedes Steckdosenelement ist beweglich an dem zugehörigen Wagen angeordnet. Die Beweglichkeit der Steckdosenelemente verbessert weitergehend das Biegeverhalten des Hochspannungskabelabschnittes, z.B. bei Kurvenfahrten des Zugverbands und/oder einem Wechsel zwischen der Normalposition und der gestauchten Position der Zwischenkupplung.In an advantageous development of the invention, the two ends of the high-voltage cable section have plug elements, the plug elements in each case being insertable into an associated socket element on an associated carriage, and each socket element is arranged movably on the associated carriage. The mobility of the socket elements further improves the bending behavior of the high-voltage cable section, e.g. when cornering the train set and / or changing between the normal position and the compressed position of the intermediate coupling.

Gemäß einer besonderen Ausgestaltung der Erfindung weist der Hochspannungskabelabschnitt im gesamten Bereich zwischen den Steckerelementen kontinuierliche Materialverläufe auf, wobei der Hochspannungsabschnitt insbesondere in einem biegsamen Metallschlauch angeordnet ist. Durch den kontinuierlichen Materialverlauf werden Unregelmäßigkeiten im Biegeverlauf des Hochspannungskanalabschnitts vermieden, die z.B. durch Verbindungsstücke entstehen können. Dies trägt dazu bei, dass mechanische Spannungen im Hochspannungskabelabschnitt vermieden werden. Der biegsame Metallschlauch kann z.B. ein Stahlgeflecht aufweisen. Dadurch wird eine Stabilität des Hochspannungskabelabschnitts erhöht.According to a special embodiment of the invention, the high-voltage cable section has continuous material runs in the entire area between the plug elements, the high-voltage section being arranged in particular in a flexible metal hose. The continuous material course prevents irregularities in the bending course of the high-voltage channel section, which e.g. can arise from connectors. This helps to avoid mechanical stresses in the high-voltage cable section. The flexible metal hose can e.g. have a steel mesh. This increases the stability of the high-voltage cable section.

Insbesondere kann der Hochspannungskabelabschnitt bogenförmig in der Aufhängungsvorrichtung aufgehängt sein, wobei an der Aufhängungsvorrichtung insbesondere ein Radius einschließlich eines zugehörigen Toleranzbereiches für eine bogenförmige Aufhängung vorgegeben sein kann. Die bogenförmige Aufhängung trägt ebenfalls zu einem günstigen Biegeverlauf im Hochspannungskabelabschnitt bei. Ein günstiger Radius am Biegeverlauf kann im Voraus berechnet werden.In particular, the high-voltage cable section can be suspended in the form of an arc in the suspension device, wherein in particular a radius including an associated tolerance range for an arc-shaped suspension can be predetermined on the suspension device. The arch-shaped suspension also contributes to a favorable bending curve in the high-voltage cable section. A favorable radius at the bend course can be calculated in advance.

Außerdem kann die Aufhängungsvorrichtung in einer Längsrichtung der Zwischenkupplung in einem mittleren Bereich der Zwischenkupplung angeordnet sein und/oder die Aufhängungsvorrichtung kann in einer Ebene angeordnet sein, die quer zu der Längsrichtung der Zwischenkupplung verläuft. Die Aufhängung in einem mittleren Bereich der Zwischenkupplung gewährleiteistet in schematischer Weise einen symmetrischen Verlauf des Hochspannungskabelabschnitts auf beiden Seiten der Aufhängungsvorrichtung. Dadurch ergibt sich eine gleichmäßige Gewichtsverteilung des Hochspannungskabelabschnitts auf beiden Seiten der Aufhängungsvorrichtung. Dadurch, dass die Aufhängungsvorrichtung senkrecht zur Längsachse der Zwischenkupplung verläuft, verläuft der Hochspannungskabelabschnitt in der Längsrichtung der Zwischenkupplung.In addition, the suspension device can be arranged in a longitudinal direction of the intermediate coupling in a central region of the intermediate coupling and / or the suspension device can be arranged in a plane that runs transversely to the longitudinal direction of the intermediate coupling. The suspension in a central area of the intermediate coupling ensures, in a schematic manner, a symmetrical course of the high-voltage cable section on both sides of the suspension device. This results in a uniform weight distribution of the high-voltage cable section on both sides of the suspension device. Because the suspension device runs perpendicular to the longitudinal axis of the intermediate coupling, the high-voltage cable section runs in the longitudinal direction of the intermediate coupling.

Weiterhin kann die Aufhängungsvorrichtung lösbar an der Zwischenkupplung befestigt sein und/oder der Hochspannungskabelabschnitt kann bei einer geraden Ausrichtung des Schienenfahrzeugs zwei vorgegebene Durchhängungen einschließlich eines jeweils zugehörigen Toleranzbereichs zwischen der Aufhängungsvorrichtung und jedem der zwei Wagen aufweisen. Die Lösbarkeit der Aufhängungsvorrichtung erleichtert die Montage und Demontage und ermöglicht ein Nachrüsten bestehender Zugverbände mit der Aufhängungsvorrichtung. Das Durchhängen des Hochspannungskabelabschnitts ist vorteilhaft, damit bei Bewegungen der Zwischenkupplung bzw. der zwei Wagen, z.B. bei Kurvenfahrten, mechanische Spannungen im Hochspannungskabelabschnitt vermieden werden.Furthermore, the suspension device can be detachably fastened to the intermediate coupling and / or the high-voltage cable section can have two predetermined slacks, including a respectively associated tolerance range, between the suspension device and each of the two carriages when the rail vehicle is aligned straight. The detachability of the suspension device facilitates assembly and disassembly and enables existing train sets to be retrofitted with the suspension device. The sagging of the high-voltage cable section is advantageous so that when the intermediate coupling or the two carriages, e.g. when cornering, avoid mechanical stresses in the high-voltage cable section.

Erfindungsgemäß weist die Aufhängungsvorrichtung drei Arme auf, wobei ein erster Arm von unten an der Zwischenkupplung befestigt ist und ein zweiter Arm und ein dritter Arm von der Zwischenkupplung weg nach unten gerichtet sind und wobei der Hochspannungskabelabschnitt zwischen dem zweiten Arm und dritten Arm gelagert ist. Die drei Arme sind eine Möglichkeit für einen Aufbau der Aufhängungsvorrichtung, die mit wenig Bauaufwand und wenig Gewicht auskommt.According to the invention, the suspension device has three arms, a first arm being attached to the intermediate coupling from below and a second arm and a third arm pointing downwards away from the intermediate coupling, and the high-voltage cable section being mounted between the second arm and third arm. The three arms are one way of constructing the suspension device, which requires little construction and little weight.

Insbesondere können die drei Arme in einem zentralen Bereich der Aufhängungsvorrichtung aufeinandertreffen und/oder einstückig ausgeführt sein. Hierdurch wird eine besonders einfache Bauweise erzielt.In particular, the three arms can meet in a central region of the suspension device and / or can be made in one piece. This results in a particularly simple construction.

Außerdem kann zwischen dem zweiten Arm und dritten Arm ein elastisches Element angeordnet sein, das den Hochspannungskabelabschnitt trägt, wobei das elastische Element bei einem Stillstand des Zugverbands insbesondere eine Durchbiegung mit einem vorgegebenen Radius einschließlich eines zugehörigen Toleranzbereichs aufweist. Das elastische Element trägt maßgeblich und vorteilhaft zu der beweglichen und federnden Lagerung bzw. Aufhängung des Hochspannungskabelabschnitts bei.In addition, an elastic element can be arranged between the second arm and the third arm, which carries the high-voltage cable section, the elastic element particularly having a deflection with a predetermined radius, including an associated tolerance range, when the tensile assembly is at a standstill. The elastic element contributes significantly and advantageously to the movable and resilient mounting or suspension of the high-voltage cable section.

In einer vorteilhaften Weiterbildung der Erfindung ist am elastischen Element eine Doppelhalterung angeordnet, bei der eine erste Halterung den Hochspannungskabelabschnitt aufnimmt und eine zweite Halterung das elastische Element aufnimmt, wobei insbesondere die erste Halterung näher an der Zwischenkupplung angeordnet ist als die zweite Halterung. Die Doppelhalterung ist ein kompaktes Bauteil zur Aufnahme des elastischen Elements und des Hochspannungskabelabschnitts. Durch die Anordnung der ersten Halterung und der zweiten Halterung ist der Hochspannungskabelabschnitt höher gelagert als das elastische Element, so dass ein möglichst großer Abstand zwischen dem Hochspannungskabelabschnitt und Gleisen für den Zugverband eingestellt werden kann.In an advantageous development of the invention, a double holder is arranged on the elastic element, in which a first holder receives the high-voltage cable section and a second holder receives the elastic element, in particular the first holder is arranged closer to the intermediate coupling than the second holder. The double bracket is a compact component for holding the elastic element and the high-voltage cable section. Due to the arrangement of the first holder and the second holder, the high-voltage cable section is mounted higher than the elastic element, so that the greatest possible distance between the high-voltage cable section and the tracks can be set for the train set.

Weiterhin kann der Hochspannungskabelabschnitt an der ersten Halterung befestigt sein und/oder das elastische Element an der zweiten Halterung befestigt sein. Dadurch wird vermieden, dass der Hochspannungskabelabschnitt innerhalb der ersten Halterung verrutscht und die zweite Halterung gegenüber dem elastischen Element verrutscht. Die erste Halterung und/oder die zweite Halterung können jeweils eine Hülse, eine Gummimanschette oder eine Schelle sein. Die Befestigung kann z.B. bei der ersten Halterung und/oder der zweiten Halterung jeweils mittels einer Übermaßpassung erfolgen.Furthermore, the high-voltage cable section can be attached to the first holder and / or the elastic element can be attached to the second holder. This prevents the high-voltage cable section from slipping within the first holder and from slipping the second holder relative to the elastic element. The first holder and / or the second holder can each be a sleeve, a rubber sleeve or a clamp. The attachment can e.g. in the case of the first holder and / or the second holder, each take place by means of an interference fit.

In vorteilhafter Weise können die erste Halterung und die zweite Halterung rechtwinklig zu einander angeordnet sein und/oder die erste Halterung und die zweite Halterung können zu einander drehbar angeordnet sein. Durch die rechtwinklige Anordnung wird der Hochspannungskabelabschnitt in Richtung der Längsrichtung der Zwischenkupplung ausgerichtet. Die Drehbarkeit ermöglicht ein noch flexibleres Nachgeben des Hochspannungskabelabschnitts.Advantageously, the first holder and the second holder can be arranged at right angles to one another and / or the first holder and the second holder can be arranged rotatable relative to one another. Due to the right-angled arrangement, the high-voltage cable section is aligned in the direction of the longitudinal direction of the intermediate coupling. The rotatability enables an even more flexible yielding of the high-voltage cable section.

Zusätzlich können mindestens zwei weitere Leitungsabschnitte mittels mindestens eines Verbindungsstückes an der Aufhängungsvorrichtung und/oder an mindestens einem zusätzlichen Winkelelement befestigt sein, wobei das Winkelelement an der Zwischenkupplung befestigt sein kann. Hierbei wird die Aufhängungsvorrichtung gleichzeitig für eine Aufhängung von anderen Arten von Leitungen verwendet, z.B. elektrische Leitungen für Hilfsbetriebe oder Schläuche, z.B. für Druckluft. Das Winkelelement verbessert die Stabilität der Befestigung des Verbindungsstücks.In addition, at least two further line sections can be attached to the suspension device and / or to at least one additional angle element by means of at least one connecting piece, wherein the angle element can be attached to the intermediate coupling. Here the suspension device is used simultaneously for suspension of other types of lines, e.g. electrical cables for auxiliary companies or hoses, e.g. for compressed air. The angle element improves the stability of the attachment of the connector.

Beispielweise kann das mindestens eine Verbindungsstück für die weiteren Leitungsabschnitte in dem zentralen Bereich der Aufhängungsvorrichtung angeordnet sein und/oder lösbar an der Aufhängungsvorrichtung befestigt sein. Hierdurch wird die Geometrie der Aufhängungsvorrichtung optimal genutzt. Die Lösbarkeit ermöglicht eine einfache Montage und Demontage sowie ein einfaches Nachrüsten bestehender Zugverbände.For example, the at least one connecting piece for the further line sections can be arranged in the central region of the suspension device and / or can be detachably attached to the suspension device. As a result, the geometry of the suspension device is optimally used. The detachability enables simple assembly and disassembly as well as simple retrofitting of existing train sets.

Speziell können die mindestens zwei Wagen Doppelstockwagen sein, insbesondere mit mindestens einem zugehörigen Personenübergang im Oberstock. Die Erfindung kann sowohl bei Zugverbänden mit einem einzelnen Stockwerk als auch bei Doppelstockzugverbänden eingesetzt werden. Bei Doppelstockzugverbänden mit Personenübergängen im Oberstock ist die Erfindung besonders vorteilhaft, denn eine Anordnung eines Hochspannungskabelabschnitts im Dachbereich ist dort aus Sicherheitsgründen nicht zulässig.In particular, the at least two carriages can be double-deck carriages, in particular with at least one associated pedestrian crossing on the upper floor. The invention can be used both with single-tier train sets and with double-deck train sets. The invention is particularly advantageous for double-decker train associations with person crossings on the upper floor, since arranging a high-voltage cable section in the roof area is not permitted there for safety reasons.

Im Folgenden wird ein Ausführungsbeispiel der Erfindung anhand von drei Figuren näher erläutert. Es zeigen:

Die Fig. 1 und 3 zeigen einen Bereich einer Zwischenkupplung 10 eines ansonsten nicht weiter dargestellten erfindungsgemäßen Zugverbands. In dem Bereich der Zwischenkupplung 10 ist die Zwischenkupplung 10 selbst dargestellt, an der eine Aufhängungsvorrichtung 20 für einen Hochspannungskabelabschnitt 30 befestigt ist. Fig. 2 zeigt einen vergrößerten Ausschnitt A aus Fig. 1 für einen Bereich der Aufhängungsvorrichtung 20.The Fig. 1 and 3rd show a region of an intermediate coupling 10 of a train assembly according to the invention which is otherwise not shown in further detail. In the area of the intermediate coupling 10, the intermediate coupling 10 itself is shown, to which a suspension device 20 for a high-voltage cable section 30 is attached. Fig. 2 shows an enlarged section A from Fig. 1 for a portion of the suspension device 20.

In den Fig. 1 bis 3 ist die Aufhängungsvorrichtung 20 in einer Ebene y/z angeordnet, die sich in einer Querrichtung y und einer senkrechten Richtung z erstreckt. Die Ebene y/z verläuft senkrecht zu einer Längsrichtung x der Zwischenkupplung 10.In the 1 to 3 the suspension device 20 is arranged in a plane y / z which extends in a transverse direction y and a vertical direction z. The plane y / z runs perpendicular to a longitudinal direction x of the intermediate coupling 10.

Wie in Fig. 2 detailliert dargestellt, weist die Aufhängungsvorrichtung 20 einen ersten Arm 21, einen zweiten Arm 22 und einen dritten Arm 23 auf. Der erste Arm 21, der zweite Arm 22 und der dritte Arm 23 treffen in einem zentralen Bereich 24 aufeinander und bilden eine auf dem Kopf stehende Y-Form. Der erste Arm 21 ist von unten an der Zwischenkupplung 10 befestigt. Zwischen dem zweiten Arm 22 und dem dritten Arm 23 ist ein elastisches Element 25 angebracht, das hier als Feder, insbesondere als Schraubenfeder ausgeführt ist und eine mögliche Ausführungsform einer elastischen bzw. federnden Aufhängung ist. Andere Arten elastischer Elemente sind ebenfalls denkbar. Das elastische Element 25 weist eine Durchbiegung auf, wobei die Durchbiegung den Radius R2 einschließlich eines zugehörigen Toleranzbereichs aufweist.As in Fig. 2 Shown in detail, the suspension device 20 has a first arm 21, a second arm 22 and a third arm 23. The first arm 21, the second arm 22 and the third arm 23 meet in a central region 24 and form an upside-down Y-shape. The first arm 21 is attached to the intermediate coupling 10 from below. An elastic element 25 is attached between the second arm 22 and the third arm 23, which is designed here as a spring, in particular as a helical spring, and is a possible embodiment of an elastic or resilient suspension. Other types of elastic elements are also conceivable. The elastic element 25 has a deflection, the deflection having the radius R2 including an associated tolerance range.

Wie in Fig. 2 weiterhin detailliert dargestellt, ist an dem elastischen Element 25 mittig eine Doppelhalterung 26 angeordnet. Die Doppelhalterung 26 umfasst eine erste Halterung 27 und eine zweite Halterung 28, die jeweils als eine zylindrische Durchführung ausgeführt sind. In der ersten Halterung 27 ist der Hochspannungskabelabschnitt 30 aufgenommen. In der zweiten Halterung 28 ist das elastische Element 25 angeordnet. Die erste Halterung 27 befindet sich oberhalb der zweiten Halterung 28, wobei die erste Halterung 27 senkrecht zur zweiten Halterung 28 angeordnet ist. Die erste Halterung 27 führt den Hochspannungskabelabschnitt 30 in der Längsrichtung x der Zwischenkupplung 10. Die zweite Halterung 28 führt das elastische Element 25 in der Querrichtung y. Die erste Halterung 27 kann gegenüber der zweiten Halterung 28 drehbar ausgeführt sein. Anstelle der Doppelhalterung 26 und des elastischen Elements 25 kann auch eine elastisch an der Zwischenkupplung 10 aufgehängte Kabelschelle verwendet werden (nicht dargestellt). Die Kabelschelle ist dann vorzugsweise drehbar aufgehängt.As in Fig. 2 further shown in detail, a double bracket 26 is arranged centrally on the elastic element 25. The double bracket 26 comprises a first bracket 27 and a second bracket 28, each of which is designed as a cylindrical bushing. The high-voltage cable section 30 is accommodated in the first holder 27. The elastic element 25 is arranged in the second holder 28. The first holder 27 is located above the second holder 28, the first holder 27 being arranged perpendicular to the second holder 28. The first bracket 27 guides the high-voltage cable section 30 in the longitudinal direction x of the intermediate coupling 10. The second bracket 28 guides the elastic element 25 in the transverse direction y. The first bracket 27 can be rotatable relative to the second bracket 28. Instead of the double bracket 26 and the elastic element 25, a cable clamp which is elastically suspended on the intermediate coupling 10 can also be used (not shown). The cable clamp is then preferably rotatably suspended.

In den Fig. 1 und 3 ist der vollständige Hochspannungskabelabschnitt 30 dargestellt. Der Hochspannungskabelabschnitt 30 weist ein erstes Ende 31 mit einem ersten Steckerelement 33 und ein zweites Ende 32 mit einem zweiten Steckerelement 34 auf. Der Hochspannungskabelabschnitt 30 ist in einem nicht explizit dargestellten rostfreien Schutzschlauch angeordnet. An dem ersten Ende 31 und dem zweiten Ende 32 ist jeweils eine Schirmrückführung mit dem Schutzschlauch verbunden. Die Schirmrückführung und der Schutzschlauch sind Bestandteile einer Erdungsausrüstung.In the Fig. 1 and 3rd the complete high voltage cable section 30 is shown. The high-voltage cable section 30 has a first end 31 with a first plug element 33 and a second end 32 with a second plug element 34. The high-voltage cable section 30 is arranged in a stainless protective hose, which is not explicitly shown. At the first end 31 and the second end 32, a shield feedback is connected to the protective tube. The shield return and the protective hose are part of a grounding equipment.

In Fig. 3 sind eine erste Steckverbindung 41 und eine zweite Steckverbindung 42 dargestellt. Die erste Steckverbindung 41 umfasst das erste Steckerelement 33 und ein erstes Steckdosenelement 43. Die zweite Steckverbindung 42 umfasst das zweite Steckerelement 34 und ein zweites Steckdosenelement 44. Eine Veränderung der Lage des ersten Steckdosenelements 43 und/oder des zweiten Steckdosenelements 44 ist möglich. Die Verschiebung ist in der Längsrichtung x (Fahrtrichtung) und/oder entgegen der senkrechten Richtung z (nach unten) möglich. Eine Verschiebung der Dose in der senkrechten Richtung z (nach oben) ist nicht möglich. Innerhalb vorgegebener Grenzen können eine erste Neigung des ersten Steckdosenelements 43 und eine zweite Neigung des zweiten Steckdosenelements 44 verändert werden.In Fig. 3 a first connector 41 and a second connector 42 are shown. The first plug connection 41 comprises the first plug element 33 and a first socket element 43. The second plug connection 42 comprises the second plug element 34 and a second socket element 44. The position of the first socket element 43 and / or the second socket element 44 can be changed. The shift is possible in the longitudinal direction x (direction of travel) and / or against the vertical direction z (downward). Moving the box in the vertical direction z (upwards) is not possible. A first inclination of the first socket element 43 and a second inclination of the second socket element 44 can be changed within predetermined limits.

Gemäß Fig. 3 ist an das erste Steckdosenelement 43 eine erste Hochspannungsleitung 45 angeschlossen. An das zweite Steckdosenelement 44 ist eine zweite Hochspannungsleitung 46 angeschlossen. Die erste Hochspannungsleitung 45 ist in einen ersten nicht dargestellten Wagen des Zugverbands angeordnet. Die zweite Hochspannungsleitung 46 ist in einem zum ersten Wagen benachbarten, ebenfalls nicht dargestellten zweiten Wagen angeordnet. Der Hochspannungskabelabschnitt 30 verbindet also die erste Hochspannungsleitung 45 des ersten Wagens mit der zweiten Hochspannungsleitung 46 des zweiten Wagens. Dabei ist die erste Hochspannungsleitung 45 in einem ersten Untergestell des ersten Wagens angeordnet. Die zweite Hochspannungsleitung 46 ist in einem zweiten Untergestell des zweiten Wagens angeordnet. In einem Bereich zwischen einem Haupttransformator und einem Trennschalter sind die erste Hochspannungsleitung 45 bzw. die zweite Hochspannungsleitung 46 außerhalb des ersten Untergestells bzw. außerhalb des zweiten Untergestells angeordnet. Die erste Hochspannungsleitung 45 und die zweite Hochspannungsleitung 46 sind jeweils in einem Metallrohr angeordnet.According to Fig. 3 a first high-voltage line 45 is connected to the first socket element 43. A second high-voltage line 46 is connected to the second socket element 44. The first high-voltage line 45 is arranged in a first carriage, not shown, of the train set. The second high-voltage line 46 is arranged in a second carriage, which is also not shown and is adjacent to the first carriage. The high-voltage cable section 30 thus connects the first high-voltage line 45 of the first car to the second high-voltage line 46 of the second car. The first high-voltage line 45 is arranged in a first base frame of the first carriage. The second high-voltage line 46 is arranged in a second base frame of the second carriage. The first high-voltage line 45 and the second high-voltage line 46 are arranged outside the first underframe or outside the second underframe in a region between a main transformer and an isolating switch. The first high-voltage line 45 and the second high-voltage line 46 are each arranged in a metal tube.

In Fig. 3 verläuft der Hochspannungskabelabschnitt 30 zwischen der ersten Steckverbindung 41 und der zweiten Steckverbindung 42 W-förmig. Das erste Steckerelement 33 ist um den Winkel α1 mit einem zugehörigen Toleranzbereich gegenüber der Längsrichtung x geneigt. Das zweite Steckerelement 34 ist um den Winkel α2 mit einem zugehörigen Toleranzbereich gegenüber der Längsrichtung x geneigt. Der Winkel α1 und er Winkel α2 sind gleich groß, z.B. fünfzehn Grad. An der Aufhängungsvorrichtung 20 weist der Hochspannungskabelabschnitt 30 einen vorgegebenen Radius R1 einschließlich eines zugehörigen Toleranzbereichs auf. Zwischen dem ersten Ende 31 und der Aufhängungsvorrichtung 20 sowie zwischen dem zweiten Ende 32 und der Aufhängungsvorrichtung 20 weist der Hochspannungskabelabschnitt 30 jeweils eine vorgegebene Durchhängung D mit einem jeweils zugehörigen Toleranzbereich auf.In Fig. 3 The high-voltage cable section 30 runs between the first plug connection 41 and the second plug connection 42 in a W-shape. The first plug element 33 is inclined by the angle α1 with an associated tolerance range with respect to the longitudinal direction x. The second plug element 34 is inclined by the angle α2 with an associated tolerance range with respect to the longitudinal direction x. The angle α1 and the angle α2 are the same size, for example fifteen degrees. On the suspension device 20, the high-voltage cable section 30 has a predetermined radius R1 including an associated tolerance range. Between the first end 31 and the suspension device 20 and between the second end 32 and the suspension device 20, the high-voltage cable section 30 each has a predetermined sag D with an associated tolerance range.

In den Fig. 1 bis 3 ist ein Winkelelement 12 dargestellt, das parallel zur Aufhängungsvorrichtung 20 an der Zwischenkupplung 10 befestigt ist. Weitere Leitungsabschnitte 51, 52, 53, 54, z.B. von elektrischen Leitungen und/oder Schläuchen, sind mittels Verbindungsstücken 61, 62, 63, 64, 65, 66 an der Aufhängungsvorrichtung 20 und dem Winkelelement 12 befestigt (Fig. 2 und 3).In the 1 to 3 An angle element 12 is shown, which is fastened to the intermediate coupling 10 parallel to the suspension device 20. Further line sections 51, 52, 53, 54, for example of electrical lines and / or hoses, are fastened to the suspension device 20 and the angle element 12 by means of connecting pieces 61, 62, 63, 64, 65, 66 ( Fig. 2 and 3rd ).

Wie in den Fig. 2 und 3 genauer gezeigt, ist der weitere Leitungsabschnitt 53 an das Verbindungsstück 64 an der Aufhängungsvorrichtung 20 angeschlossen. Das Verbindungsstück 64 ist an das Verbindungsstück 65 zwischen der Aufhängungsvorrichtung 20 und dem Winkelelement 12 angeschlossen. Das Verbindungsstück 65 ist an das Verbindungsstück 66 angeschlossen. Der weitere Leitungsabschnitt 54 ist an das Verbindungsstück 66 angeschlossen.As in the Fig. 2 and 3rd Shown in more detail, the further line section 53 is connected to the connecting piece 64 on the suspension device 20. The connecting piece 64 is connected to the connecting piece 65 between the suspension device 20 and the angle element 12. The connector 65 is connected to the connector 66. The further line section 54 is connected to the connecting piece 66.

Wie in den Fig. 2 und 3 ebenfalls genauer gezeigt, ist der weitere Leitungsabschnitt 51 an das Verbindungsstück 61 an der Aufhängungsvorrichtung 20 angeschlossen. Das Verbindungsstück 61 ist an das Verbindungsstück 62 zwischen der Aufhängungsvorrichtung 20 und dem Winkelelement 12 angeschlossen. Das Verbindungsstück 62 ist an das Verbindungsstück 63 angeschlossen. Der weitere Leitungsabschnitt 52 ist an das Verbindungsstück 63 angeschlossen.As in the Fig. 2 and 3rd also shown in more detail, the further line section 51 is connected to the connecting piece 61 on the suspension device 20. The connecting piece 61 is connected to the connecting piece 62 between the suspension device 20 and the angle element 12. The connecting piece 62 is connected to the connecting piece 63. The further line section 52 is connected to the connecting piece 63.

Bei einem Betrieb des Zugverbands kann der Hochspannungskabelabschnitt 30 Auslenkungen der Zwischenkupplung 10 folgen, wobei mechanische Belastungen des Hochspannungskabelabschnitts 30 vermieden werden. Die Auslenkungen der Zwischenkupplung 10 erfolgen aufgrund von Auslenkungen des ersten Wagens gegenüber dem zweiten Wagen, z.B. bei Kurvenfahrten. Die Aufhängungsvorrichtung 20, insbesondere das elastische Element 25, und die beiden Durchhängungen D bewirken, dass der Hochspannungskabelabschnitt 30 allen auftretenden räumlichen und fahrttechnischen Randbedingungen sowie statischen und dynamischen mechanischen Beanspruchungen standhält. Bei einer mechanischen Auslenkung des ersten Wagens gegenüber dem zweiten Wagen ist eine mechanische Beanspruchung des Hochspannungskabelabschnitts 30 in einem mittleren Bereich 11 der Zwischenkupplung 10 am geringsten, insbesondere in der Längsrichtung x.When the train set is in operation, the high-voltage cable section 30 can follow deflections of the intermediate coupling 10, mechanical loads on the high-voltage cable section 30 being avoided. The deflections of the intermediate coupling 10 take place due to deflections of the first carriage relative to the second carriage, e.g. when cornering. The suspension device 20, in particular the elastic element 25, and the two slacks D have the effect that the high-voltage cable section 30 withstands all spatial and driving-related boundary conditions as well as static and dynamic mechanical stresses that occur. When the first carriage is mechanically deflected relative to the second carriage, mechanical stress on the high-voltage cable section 30 is lowest in a central region 11 of the intermediate coupling 10, in particular in the longitudinal direction x.

Der Hochspannungskabelabschnitt 30 kann also Bewegungen des ersten Wagens gegenüber dem zweiten Wagen in der Längsrichtung x, der Querrichtung y und der senkrechten Richtung z. sowie auch in den jeweils entgegengesetzten Richtungen nachgeben. Der Winkel α1 des ersten Steckerelements 33 und der Winkel α2 des zweiten Steckerelements 34 können während der Fahrt, z.B. in Kurven, variieren, da das erste Steckdosenelement 43 und das zweite Steckdosenelement 44 innerhalb vorgegebener Grenzen beweglich sind.The high-voltage cable section 30 can thus movements of the first carriage relative to the second carriage in the longitudinal direction x, the transverse direction y and the vertical direction z. as well as yield in opposite directions. The angle α1 of the first connector element 33 and the angle α2 of the second connector element 34 can be changed while driving, e.g. in curves, because the first socket element 43 and the second socket element 44 are movable within predetermined limits.

Eine Anordnung der Aufhängungsvorrichtung 20 an der Zwischenkupplung 10 ist besonders bei Doppelstockzugverbänden mit Personenübergängen im Oberstock anwendbar.An arrangement of the suspension device 20 on the intermediate coupling 10 is particularly applicable to double-decker train associations with person crossings on the upper floor.

Eine Aufhängung des Hochspannungskabels 30 an der Zwischenkupplung 10 ist gemäß dem Ausführungsbeispiel möglich, jedoch sind auch andere Aufhängungsarten denkbar.A suspension of the high-voltage cable 30 on the intermediate coupling 10 is possible according to the exemplary embodiment, but other types of suspension are also conceivable.
