Description

The invention relates to a train with at least one suspension device to which at least one high voltage cable section is suspended.

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. 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. In addition, arise in the cables outside the junction box unfavorable bending radii in the area of the connections on the junction box when the train travels 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. When 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. In an underframe area arrangement, the cable connection rests on a pulley 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 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.

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.

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.

One advantage is that flexibility of the high voltage cable section and a movable and resilient bearing ensure favorable bending radii on the high voltage cable section and thus favorable bending behavior of the entire high voltage cable section, e.g. when the train is moving 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 coupling may e.g. be an automatic clutch or a permanent clutch. Due to the movable and elastic mounting or suspension, the high voltage cable section on the suspension device can adapt to any movement of the intermediate clutch and the two carriages. In addition, wear on the high voltage cable section is avoided.

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, eg when cornering the train and / or a change between the normal position and the compressed position of the intermediate coupling.

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.

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.

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.

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.

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.

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.

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 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, wherein 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.

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 The first holder and / or the second holder may each be a sleeve, a rubber sleeve or a clamp. The attachment can be done, for example, in the first holder and / or the second holder each by means of an interference fit.

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.

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.

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.

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.
