    - Figure 1 is a partial perspective view of a rail vehicle according to an exemplary embodiment of the invention, at an intercirculation between two successive cars of the rail vehicle;
    - Figure 2 is a front view of a cable support member fitted to the rail vehicle of Figure 1.
    FIG. 1 shows a railway vehicle designated by the general reference 10.
    The rail vehicle 10 comprises at least two cars, in particular a first car 12 and a second car 14 adjacent, conventionally separated by an interconnecting space 16 comprising an interconnecting device.
    The rail vehicle 10 comprises for example other cars not shown, all the adjacent cars being advantageously connected together in the same way as the first 12 and second 14 cars.
    The first car 12 comprises a first body 13 comprising a first roof 13T and extending in a longitudinal direction to a first end 13A.
    Likewise, the second car 14 comprises a second body 15 comprising a second roof 15T and extending in a longitudinal direction to a second end 15A.
    The first 13A and second 15A ends are arranged opposite one another.
    The intercirculation device conventionally comprises mechanical connection means of the first 12 and second 14 cars together, to ensure the cohesion of the rail vehicle 10, while allowing relative rotations of the first and second 14 cars, for the passage of the curves. , hollows and bumps in the track.
    The rail vehicle 10 comprises an electricity distribution network 18 extending along this rail vehicle, in particular on the first car 12 and on the second car 14. The distribution network 18 is intended to distribute electricity on along the rail vehicle 10 for the electrical supply of electrical equipment of the rail vehicle 10, in particular electric motors conventionally ensuring the traction of the vehicle 10, and of auxiliary equipment such as lighting systems, display systems , air conditioning systems, etc.
    More particularly, the first car 12 comprises first electric cables for distributing electricity, comprising first high voltage electric cables 20H and first low voltage electric cables 20B, and the second car 14 comprises second electric cables, comprising second cables high voltage electrical cables 22H and second low voltage electrical cables 22B.
    For example, at least some cables, in particular the low voltage electric cables 20B, 22B, extend over the two cars 12, 14, and in other words are common to the two cars 12, 14.
    On the other hand, at least certain cables, in particular the high-voltage electric cables 20H, 22H, are connected to each other by means of intermediate high-voltage cables 24H which extend in the interconnection space 16, and which will be described later in more detail. More particularly, each first high voltage cable 20H is connected to a respective second high voltage cable 22H, by means of a respective intermediate cable 24H.
    The first 20H, 20B and second 22H, 22B cables connected to each other together form the distribution network 18.
    According to a variant, the high voltage electric cables 20H, 22H are directly connected to each other without any intermediary. According to another variant, the high-voltage electric cables extend over the two cars 12, 14, and in other words are common to the two cars 12, 14.
    According to the invention, the first car 12 carries, near its first end 13A, a first member 26 for supporting and guiding the first high voltage 20H and low voltage 20B electric cables.
    Advantageously, the first car 12 comprises a first box 28 carried at its first end 13A, the first high voltage electric cables 20H and low voltage 20B all passing through this first box 28. By grouping the high voltage and the low voltage in the same box , it facilitates the implementation of the distribution network 18, in particular with regard to assembly, disassembly, maintenance, etc.
    The first housing 28 extends transversely to the first car 12, substantially over the entire width of this first car 12. The first housing 28 comprises in particular two transverse walls, separated in the longitudinal direction, and a cover (not shown in the figure ) closing the first housing 28 upwards and preferably also on the sides. One of the transverse walls is formed by the first support member 26, which is shown in more detail in FIG. 2.
    The first housing 28, in particular the first support member 26, is carried integrally by the roof 13T of the first box 13.
    The first support member 26 comprises a plurality of first guide holes 29, each for guiding a respective first cable 20H, 20B. Each first guide hole 29 is oriented downwards in the longitudinal direction, in a first direction going from the first car 12 to the second car 14. Thus, the cables are guided downwards out of the first support member 26, in the traffic space 16, as shown in FIG. 1.
    The first support member 26 comprises a part 26H for supporting the first high voltage cables 20H, and a part 26B for supporting the first low voltage cables 20B, the parts 26H and 26B being separate.
    The first guide holes 29 include high voltage guide holes 29H, formed in the part 26H for supporting the first high voltage cables 20H, and low voltage guide holes 29B, formed in the part 26B for supporting the first low voltage cables 20B.
    Each high voltage guide hole 29H is for example intended to receive a high voltage connector, suitable for being connected on the one hand to one of the first high voltage cables 20H, on the side of the first housing 28, and on the other hand to one of the 24H intermediate cables on the side of the intercirculation space 16.
    Furthermore, each low voltage guide orifice 29B is for example intended for the passage of low voltage cables 20B, 22B.
    As a variant, at least certain cables, in particular the low-voltage electric cables 20B, 22B, are connected to each other by means of intermediate low-voltage cables which extend in the interconnection space 16. In this variant, each guide orifice low voltage 29B is for example intended to receive a high voltage connector, suitable for being connected on the one hand to one of the first low voltage cables 20B, on the side of the first housing 28, and on the other hand to one of the low-voltage intermediate cables on the side of the traffic space 16.
    The second car 14 carries, near its second end 15A, a second member 30 for supporting and guiding the second high voltage 22H and low voltage 22B electric cables.
    Advantageously, the second car 14 includes a second housing 32 carried at its second end 15A, the second high voltage electric cables 22H and low voltage 22B all passing through this second housing 32. By grouping the high voltage and the low voltage in the same housing , it facilitates the implementation of the distribution network 18, in particular as regards assembly, disassembly, maintenance, etc.
    The second housing 32 extends transversely to the second car 14, substantially over the entire width of this second car 14. The second housing 32 in particular comprises two transverse walls, separated in the longitudinal direction, and a cover (not shown in the figure ) closing the second housing 32 upwards and preferably also on the sides. One of the transverse walls is formed by the second support member 30.
    The second housing 32, in particular the second support member 30, is carried integrally by the roof 15T of the second box 15.
    The second support member 30 is similar in all respects to the first support member 26.
    In particular, the first support member 30 includes a plurality of second guide holes, each for guiding a second cable 22H, 22B respectively. Each second guide hole is oriented downwards in the longitudinal direction, in a second direction going from the second car 14 to the first car 12. Thus, the cables are guided downwards out of the second support member 30, in the circulation space 16, as shown in FIG. 1.
    Similarly to the first support member 26, the second support member 30 includes a support portion for the second high voltage cables 22H, and a support portion for the second low voltage cables 22B.
    The second guide holes include high voltage guide holes, formed in the support part of the second high voltage cables 22H, and low voltage guide holes, formed in the support part of the second low voltage cables 22B.
    Each high voltage guide orifice is for example intended to receive a high voltage connector, suitable for being connected on the one hand to one of the second high voltage cables 22H, on the side of the second housing 32, and on the other hand to the 'one of the 24H intermediate cables on the side of the interconnection space 16.
    Furthermore, each low voltage guide orifice is for example intended for the passage of low voltage cables 20B, 22B.
    The second support member 30 is arranged opposite the first support member 26, in a symmetrical manner, so that the high voltage part 26H of the first support member 26 is arranged opposite the high voltage part of the second support member 30 , and that the low voltage part 26B of the first support member 26 is arranged opposite the low voltage part of the second support member 30.
    In the example shown in Figure 1, each first high voltage cable 20H is connected to a second high voltage cable 22H located opposite. As a variant, the cables are crossed and are therefore connected to cables which are not facing each other.
    According to the invention, the electric cables, in particular the low voltage cables 20B, 22B and the intermediate cables 24H, extend freely in the intercirculation space 16 between the first 26 and second 30 support members, the space intercirculation 16 and in particular the intercirculation device being devoid of any support element for the electric cables. In other words, the only support elements are formed by the support members 26, 30, which are not carried by elements of the intercirculation space 16 and in particular of the intercirculation device, but by the body 13, 15 respectively.
    Thus, the cables are not subject to any stress during travel between the first and second cars.
    Furthermore, since the intercirculation device does not carry a support element, the invention can be used in a standardized manner regardless of the type of intercirculation device.
    It will be noted that the invention is not limited to the embodiment described above, and could present various complementary variants.
