The area (5) bridging the gap between two segments (2,3,4) of the articulated vehicle (1) is fitted with a movable joint with a turntable on top and covered by vertically positioned pleated rubber walls. The turntable is inserted in an inclined position joined with one side to the floor of one of the vehicle segments (2,3,4) and with the opposite side to an elastic element.

Description

The present invention relates to a bridge with a hub of a transition between two interconnected by a joint vehicles, the hub is connected at one end by an elastic intermediate member to the bottom of the vehicle in communication.

Articulately interconnected vehicles are, for example in the form of articulated buses, but also in the form of rail vehicles, z. As trams, known. Rail vehicles, and in particular trams, have a plurality of bogies, in the bogies, ie in front of or behind the bogies, the individual vehicles or vehicle parts are connected by joints. In the area of the joints is a transition, wherein the transition comprises a transition bridge and a bellows, which is known to encompass both the transition bridge and the joint to the persons in the vehicle the transition from one vehicle to the other vehicle, exposed to the weather to be possible.

From the FR 258101 A1 is a connection between two parts of an articulated vehicle is known, are provided in the region of the transition inclined floor panels. The horizontally extending hubs are located above the joint outside the transitional area between the parts of the articulated vehicle.

As is known, articulated vehicles must be able to follow the most varied movements during their journey. In particular, such a vehicle must enable kinking movements, such as occur when such a vehicle drives through a curve. In addition, pitching movements must be made possible, as occur when such a vehicle travels over a crest or through a depression. To a certain extent, rolling movements should also be able to be accommodated, as occur, for example, when the vehicles are rotated against one another. In addition, it should be noted that the described movements can also occur superimposed on each other. In particular, in the area of a turntable arise when cornering, so with a bending movement and possibly superimposed rolling and pitching movements, extremely complex movements in the hub, for example, if one considers a point on the outer circumference of the turntable.

The DE 41 38 921 A1 shows a low-build, disc-shaped platform for low-floor articulated buses, the platform is self-supporting, but elastically deformable in the vertical direction.

From the DE 94 13 285.2 U1 , is known in this context, a rail vehicle, wherein between the turntable of the rail vehicle and the bottom of the vehicle an elastic connection in the form of an elastic hinge in the manner of a hollow profile made of an elastomer is provided.

Modern tram trains are especially designed so that they also allow wheelchair users the opportunity to get directly from the platform edge in the vehicle, possibly also by means of a ramp in the door entry in the sense of barrier-free access. For this purpose, the vehicles are designed low-floor at least in the area of an entry. Such a low-floor, however, limits are set in the range of the rotary joint, since the hinge can not fall below a certain minimum height. In order to enable a barrier-free transition between the individual vehicles of such a hinge, it is further proposed that the turntable extends obliquely over the joint, wherein the inclined turntable is at its other end in communication with the vehicle floor of the other vehicle.

The connection from the hub to the bottom of the vehicle can be done directly, or indirectly by a dome plate. The same applies mutatis mutandis to the transition from the elastic intermediate member to the vehicle floor. Again, a dome plate may be provided which is rigidly connected to the ground.

In order to prevent that when moving the vehicles relative to each other, the turntable with respect to the floor of the vehicle lifts or lowers, is provided according to a further feature of the invention that the hub is held clamped in the transition to the bottom of a vehicle. As already explained elsewhere, the turntable rotates when cornering relative to the vehicle floor and thus has on its the bottom of a vehicle part facing end face on a circular arc-shaped training. Due to the clamped mounting of the turntable in the transition region to the bottom of a vehicle part is now achieved that the hub can indeed rotate within this clamping relative to the ground, but this can not stand out or lower.

It has also been explained elsewhere that the vehicles must also be able to execute pitching movements as they occur when such vehicles drive over crests or through depressions. In this respect, it is provided that the parts forming the bridge are arranged displaceably parallel to the longitudinal axis of the vehicle, in particular the hub is slidably clamped along its front-side circumference relative to the bottom of a vehicle parallel to the longitudinal axis of the vehicle. This means that the turntable can move relative to the ground in the vehicle's longitudinal axis. In order to accomplish such a clamping is further provided in detail, that provided between the end face of the hub and the bottom or dome plate, a circumferential gap, wherein the clamped holder of the Turntable is provided a clamping bar which covers the edge region of the hub and the dome plate, and which is connected to a counter bar under the hub and the dome plate.

In this context, it should be noted that the arrangement of such a gap is basically possible in the transition to the floor of the other vehicle. It is essential only the possibility of displacement of the bridge or parts of the bridge to allow such a shortening or extension of the bridge.

In order to ensure that even when loading the clamping bar, the hub can easily rotate, is provided between clamping bar and turntable and a slide bar, for example made of plastic. Such a sliding strip is also advantageous between the counter ledge on the one hand and the turntable and the dome plate on the other hand arranged.

The elastic intermediate member, which is formed as a plate is connected in particular by connecting strips with each of the vehicle floor and the turntable. Advantageously, a dome plate can also be provided between the bottom of the other vehicle and the elastic intermediate member, this dome plate is connected on the one hand with the elastic intermediate member and on the other hand to the vehicle floor of the other vehicle. It should again be noted at this point that it is essentially irrelevant to the invention whether the vehicle floor is directly connected to the turntable or the elastic intermediate member or by a dome plate.

According to a further feature of the invention, it is provided that the end edge of the turntable extends in the transition to the elastic intermediate member through the pivot point of the joint. It is also provided that the bottom of the other vehicle is formed arrow-shaped extending in the transition to the elastic intermediate member, wherein the elastic intermediate member extends corresponding thereto. The tip of the arrow-shaped course of the soil, or in the event that a dome plate finds application also the dome plate, this ends in the region of the pivot point of the rotary joint, which connects the two vehicles hinged together.

The tram line marked 1 comprises the three vehicles 2, 3 and 4, which communicate with each other through the transitions 5. In the area of the transitions 5, the Schienengelenkzug the two bogies 6. If such a vehicle drives around a curve, for example, then the tram train follows the course of the curve by bending in the region of the transitions 5.

The subject of the invention is now the bridge 10 as part of the overall transition (5) ( Fig. 2 ff). The bridge 10, comprising the hub 20, the elastic intermediate member 30 and the dome plate 40 and the dome plate 50 is located obliquely above the joint designated 60 for connection of the two vehicles 3, as is apparent from FIG. 2 results. The bridge 10 as well as the joint 60 is surrounded by the bellows designated overall by 15, as this is particularly the case in the view of FIG Figures 2 and 3 results. In particular from FIG. 3 It can be seen that the end edge 21 of the hub 20 passes through the pivot point 61 of the joint 60. The dome plate 40 is formed in the direction of the end edge 21 to arrow-shaped (arrow 45), the tip of the arrow-shaped dome plate 40 centrally to the pivot point (61) of the joint 60 assigns. The elastic intermediate member 30 ultimately follows the course of both the turntable 20 in this area and the dome plate 40. Such a design of the elastic intermediate member 30 has been found to be advantageous in that through this design in the middle region of this elastic intermediate member 30, the lowest stresses occur.

Looking now at the FIG. 5 as a section of the line V - V out FIG. 4 , one recognizes as well as from the FIG. 6 Specifically, in this case, a clamping bar 25 is provided, wherein the clamping bar 25 is connected by arcuately arranged screws 26 with the dome plate 50. Between the clamping bar 25 and the turntable 20 on the one hand and the dome plate 50 on the other hand is a slide bar 27 to ensure a relative movement of the hub 20 to the dome plate 50 and thus ultimately to the bottom of the coupled vehicle.

Now consider the section according to the FIG. 6 it can be seen that there the dome plate 50 is connected to the counter ledge 55 by screws 56. Also here is located between the hub 20 and the dome plate 50 on the one hand and the counter ledge 55 on the other hand, a slide bar 57 to the relative movement of the hub 20 on the one hand to the counter ledge 55, which - as already stated - is rigidly connected to the dome plate 50 by the screws 56. Visible is between the end face 22, the hub 20 and the end face 53 of the dome plate 50, a gap 70 recognizable, with a gap 75 also in the clamping bar 25, and here in particular between the front edge of the slide bar 27 and a stage 23 of the hub 20th is provided, wherein the two columns 70, 75 serve to allow a pitching movement of the vehicles connected in this way.

The connection of the elastic intermediate member 30 with the dome plate 40 on the one hand and the turntable 20 on the other hand is in FIG. 7 shown. The elastic intermediate member 30, which consists of an elastomer or an elastic plastic, is screwed by the connecting strips 35 each with the dome plate 60 and the hub 20. The elastic intermediate member 30 has on its upper side a wear-resistant surface 31, which can be accomplished in particular by the support of a thin sheet.
