Definitions
- the invention relates to a train with at least one suspension device to which at least one high voltage cable section is suspended.
- a train In the field of rail vehicle technology, it is known that a train can have two pantographs. These can each be arranged on a final carriage of the train. 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. Cable bridges between the car transitions. The high voltage line also runs through disconnectors and main transformers.
- the publication EP 1 415 883 B1 describes a junction box to which electrical cables are connected.
- electrical lines In the interior of the junction box electrical lines are housed, connect the both sides of the junction box connected electrical cable with each other.
- the junction box is attached to an intermediate coupling of a drawstring.
- the disadvantage here is that the construction cost and weight are very high.
- unfavorable bending radii result in the area of the connections on the connection box when the train is traveling through curves. This can cause cable wear in the area of the connections on the junction box.
- the publication FR 2 713 183 B1 discloses a train assembly in which a cable transition for power lines in the roof area between two cars is arranged.
- the cable transition is attached to a telescopic pole.
- cornering shortened or extended the telescopic rod. Again, it is disadvantageous that a high construction cost is required. In addition, there is a wear in the telescopic rod.
- the publication JP 2602968 Y relates to a cable connection between two cars of a train.
- the cable connection can be arranged in the roof area or in the underframe area.
- the cable connection rests on a pulley which is attached to one of the two carriages.
- the disadvantage here is that in an addition of Dirt, ice, sand or the like between the roller and the cable connection material damage to the cable connection can be made. With electric cables, this can lead to dangerous situations.
- the invention is therefore based on the object to provide a train in which a high voltage cable connection is suspended between two cars, the high voltage cable connection in curves has favorable bending radii, a low construction cost is required and wear is avoided.
- the solution to the problem lies in a train with at least one suspension device on which at least one high-voltage cable section is suspended, wherein the train comprises at least two carriages and the suspension device receives the high-voltage cable section between two adjacent carriages of the train and each high-voltage cable section has two ends, each connected via a plug connection with a respective associated high voltage line in a respective associated carriage, wherein the suspension device is attached to a mechanical intermediate coupling between the two cars.
- the entire high voltage cable section is flexible and is movably and elastically supported on the suspension device.
- An advantage is that a flexibility of the high voltage cable section and a movable and elastic or resilient or yielding storage 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 moves 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 are favorable at the high-voltage cable section.
- the intermediate clutch may be, for example, an automatic clutch or a permanent clutch. Due to the movable and elastic mounting or suspension, the high-voltage cable section can on the suspension device, adjust each movement of the intermediate clutch and the two carriages. In addition, wear on the high voltage cable section is avoided.
- the two ends of the high-voltage cable section have plug elements, wherein the plug elements can each be plugged into an associated socket element on a respectively associated carriage, and each socket element is movably arranged 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 and / or a change between the normal position and the compressed position of the intermediate clutch.
- the high-voltage cable section in the entire region between the plug elements on continuous material gradients, wherein the high-voltage portion is arranged in particular in a flexible metal tube.
- the continuous course of the material avoids irregularities in the bending curve of the high-voltage channel section, which are e.g. can arise through connectors. This helps to avoid mechanical stresses in the high voltage cable section.
- the flexible metal tube may e.g. have a steel mesh. As a result, a stability of the high voltage cable section is increased.
- the high-voltage cable section can be suspended in an arcuate manner in the suspension device, wherein in particular a radius including an associated tolerance range for an arcuate suspension can be specified on the suspension device.
- the bow-shaped suspension also contributes to a favorable bending curve in the high-voltage cable section. A favorable radius on the bend can be calculated in advance.
- the suspension device may be arranged in a longitudinal direction of the intermediate clutch in a central region of the intermediate clutch and / or the suspension device may be arranged in a plane which extends transversely to the longitudinal direction of the intermediate clutch.
- the suspension in a central region of the intermediate coupling schematically ensures 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. Characterized in that the suspension device is perpendicular to the longitudinal axis of the intermediate coupling, the high voltage cable section extends in the longitudinal direction of the intermediate coupling.
- the suspension device may be releasably attached to the intermediate coupling and / or the high voltage cable section may have two predetermined sags including a respective associated tolerance range between the suspension device and each of the two carriages in a straight alignment of the rail vehicle.
- the releasability of the suspension device facilitates assembly and disassembly and allows for retrofitting existing drawstrings with the suspension device.
- the sagging of the high-voltage cable section is advantageous in order that during movements of the intermediate coupling or the two cars, e.g. When cornering, avoid mechanical stresses in the high voltage cable section.
- the suspension device comprises three arms, wherein a first arm is fixed to the intermediate coupling from below and a second arm and a third arm are directed away from the intermediate coupling and wherein the high voltage cable portion between the second arm and third Arm is stored.
- the three arms are one way for a structure of the suspension device, which requires little construction and little weight.
- the three arms can meet in a central region of the suspension device and / or be made in one piece. As a result, a particularly simple construction is achieved.
- an elastic element may be arranged, which carries the high-voltage cable section, wherein the elastic element in particular has a deflection with a predetermined radius including an associated tolerance range at a standstill of the drawstring.
- the elastic element contributes significantly and advantageously to the movable and resilient mounting or suspension of the high voltage cable section.
- 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 support is a compact component for receiving the elastic element and the high voltage cable section.
- the high-voltage cable section may be fastened to the first holder and / or the elastic element may be fastened to the second holder. This prevents the high-voltage cable section from slipping inside the first holder and from slipping the second holder relative to the elastic element.
- the first holder and / or the second holder may each be a sleeve, a rubber boot or a clamp.
- the attachment may e.g. in the case of the first holder and / or the second holder, in each case by means of an interference fit.
- first holder and the second holder may be arranged at right angles to each other and / or the first holder and the second holder may be rotatably arranged to each other. Due to the rectangular arrangement of the high voltage cable section is aligned in the direction of the longitudinal direction of the intermediate coupling. The rotation allows a more flexible yielding of the high voltage cable section.
- At least two further line sections may be fastened 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 may be fastened to the intermediate coupling.
- the suspension device is used simultaneously for suspension of other types of conduits, e.g. electrical cables for auxiliary equipment or hoses, e.g. for compressed air.
- the angle element improves the stability of the attachment of the connector.
- the at least one connecting piece for the further line sections may be arranged in the central region of the suspension device and / or be fastened detachably to the suspension device.
- the geometry of the suspension device is used optimally. The solvability allows easy assembly and disassembly and easy retrofitting existing train assemblies.
- the at least two cars can be double-deck cars, in particular with at least one associated passenger crossing in the upper floor.
- the invention can be used both in single-floor train assemblies and in double-deck train assemblies. In the case of double-decker trains with person transitions in the upper floor, the invention is particularly advantageous because an arrangement of a high-voltage cable section in the roof area is not permitted there for safety reasons.

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 with a train 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 solution to the problem lies in a train with at least one suspension device on which at least one high-voltage cable section is suspended, wherein the train comprises at least two carriages and the suspension device receives the high-voltage cable section between two adjacent carriages of the train and each high-voltage cable section has two ends, each connected via a plug connection with a respective associated high voltage line in a respective associated carriage, wherein the suspension device is attached to a mechanical intermediate coupling between the two cars. 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.An advantage is that a flexibility of the high voltage cable section and a movable and elastic or resilient or yielding storage 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 moves 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 are favorable at the high-voltage cable section. The intermediate clutch may be, for example, an automatic clutch or a permanent clutch. Due to the movable and elastic mounting or suspension, the high-voltage cable section can on the suspension device, adjust each movement of the intermediate clutch and the two carriages. In addition, wear on the high voltage cable section is 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, wherein the plug elements can each be plugged into an associated socket element on a respectively associated carriage, and each socket element is movably arranged 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 and / or a change between the normal position and the compressed position of the intermediate clutch.
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 particular embodiment of the invention, the high-voltage cable section in the entire region between the plug elements on continuous material gradients, wherein the high-voltage portion is arranged in particular in a flexible metal tube. The continuous course of the material avoids irregularities in the bending curve of the high-voltage channel section, which are e.g. can arise through connectors. This helps to avoid mechanical stresses in the high voltage cable section. The flexible metal tube may e.g. have a steel mesh. As a result, a stability of the high voltage cable section is increased.
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 an arcuate manner in the suspension device, wherein in particular a radius including an associated tolerance range for an arcuate suspension can be specified on the suspension device. The bow-shaped suspension also contributes to a favorable bending curve in the high-voltage cable section. A favorable radius on the bend 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 may be arranged in a longitudinal direction of the intermediate clutch in a central region of the intermediate clutch and / or the suspension device may be arranged in a plane which extends transversely to the longitudinal direction of the intermediate clutch. The suspension in a central region of the intermediate coupling schematically ensures 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. Characterized in that the suspension device is perpendicular to the longitudinal axis of the intermediate coupling, the high voltage cable section extends 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 may be releasably attached to the intermediate coupling and / or the high voltage cable section may have two predetermined sags including a respective associated tolerance range between the suspension device and each of the two carriages in a straight alignment of the rail vehicle. The releasability of the suspension device facilitates assembly and disassembly and allows for retrofitting existing drawstrings with the suspension device. The sagging of the high-voltage cable section is advantageous in order that during movements of the intermediate coupling or the two cars, e.g. When cornering, avoid mechanical stresses in the high voltage cable section.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung 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 an advantageous embodiment of the invention, the suspension device comprises three arms, wherein a first arm is fixed to the intermediate coupling from below and a second arm and a third arm are directed away from the intermediate coupling and wherein the high voltage cable portion between the second arm and third Arm is stored. The three arms are one way for a structure of 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 be made in one piece. As a result, a particularly simple construction is achieved.
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, between the second arm and third arm, an elastic element may be arranged, which carries the high-voltage cable section, wherein the elastic element in particular has a deflection with a predetermined radius including an associated tolerance range at a standstill of the drawstring. 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 support is a compact component for receiving the elastic element and the high voltage cable section. By arranging the first holder and the second holder, the high voltage cable portion is mounted higher than the elastic element, so that the largest possible distance between the high voltage cable section and tracks for the train can be adjusted.
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 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 may be fastened to the first holder and / or the elastic element may be fastened to the second holder. This prevents the high-voltage cable section from slipping inside the first holder and from slipping the second holder relative to the elastic element. The first holder and / or the second holder may each be a sleeve, a rubber boot or a clamp. The attachment may e.g. in the case of the first holder and / or the second holder, in each case 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 may be arranged at right angles to each other and / or the first holder and the second holder may be rotatably arranged to each other. Due to the rectangular arrangement of the high voltage cable section is aligned in the direction of the longitudinal direction of the intermediate coupling. The rotation allows a 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 may be fastened 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 may be fastened to the intermediate coupling. Here, the suspension device is used simultaneously for suspension of other types of conduits, e.g. electrical cables for auxiliary equipment 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 may be arranged in the central region of the suspension device and / or be fastened detachably to the suspension device. As a result, the geometry of the suspension device is used optimally. The solvability allows easy assembly and disassembly and easy retrofitting existing train assemblies.
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.Specifically, the at least two cars can be double-deck cars, in particular with at least one associated passenger crossing in the upper floor. The invention can be used both in single-floor train assemblies and in double-deck train assemblies. In the case of double-decker trains with person transitions in the upper floor, the invention is particularly advantageous because an arrangement of a high-voltage cable section in the roof area is not permitted there for safety reasons.

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.During operation of the drawstring, the high
