Description

The invention relates to a transition between two vehicles, in particular between two rail vehicles, with a transition bridge and with a bellows which is connected to the vehicle at one end and which has a coupling frame at its other end.
The transition represents the connection between two vehicles. It can be formed in one part or in two parts, the transition being composed of two transition halves in the case of a two-part construction. In this latter case, the dome frames represent the links between the two halves. In the following, the term transition therefore includes both the two-part and the one-part embodiment.

Transitions of the type mentioned at the outset are known (EP-OS 0 331 121). Such transitions are often used as a connection between so-called railcars; Railcars are rail vehicles in which each car is able to act independently as a towing vehicle. Such railcar trains are uncoupled when a certain section of the route is reached, each of these trains then traveling in a different direction for itself. In the separation, it was previously necessary to pull the transitions between two railcars by hand to the vehicle after uncoupling and to fix them there. On the one hand, this is labor-intensive and naturally also takes a certain amount of time.

The invention is therefore based on the object of developing a transition of the type mentioned in such a way that when the railcars of a railcar train are uncoupled, the transitions are automatically retracted into their starting position.

The object is achieved in that the transition is displaceable by means of a piston-cylinder drive arranged on the vehicle; the piston-cylinder drive means that the transition to the vehicle after the uncoupling process is used in its end position. In particular, the transition according to the invention is characterized in that the piston-cylinder drive is connected to a travel device which is connected to the transition. The piston-cylinder drive thus does not act directly on the transition, but rather indirectly through the travel device.

This ensures that driving movements are not transmitted to the piston-cylinder drive, thus avoiding damage to the drive.

The transition bridge, which is preferably in the manner of a parallel link, e.g. is designed as a link bridge, in order to be able to compensate for lateral movements during cornering of the train, is connected on the coupling frame side, in particular by articulation to the coupling frame, with the bellows and on the vehicle side with the travel device. It follows from this that when the travel device moves, the bellows performs a corresponding movement.

According to a particularly advantageous feature of the invention, the traversing device consists of two traversing elements, the one traversing element being designed as a slide which can be coupled to the second traversing element designed as a roller carriage. The carriage is only coupled to the roller carriage if the transition or the bellows is to be used on the vehicle. For coupling the carriage to the roller carriage, at least one coupling device is provided for this purpose, which has a pivotable hook which engages in corresponding recesses in the opposite part; the hook can also be actuated by means of a piston-cylinder drive.

In the uncoupled state, the slide, which is connected to the transition bridge, and the roller carriage are mounted so as to be movable relative to one another, which is advantageously done the slide is slidably arranged on the side members of the roller carriage. Due to this design, driving movements that occur can be yielded, so that a transfer of these movements to the piston-cylinder drive is excluded. To guide the carriage on the roller carriage, the carriage has lateral guide rollers which bear against the inner surfaces of the side members.

In order to prevent the carriage from being lifted off the roller carriage, the carriage has shoes on its underside which engage under the respective longitudinal member.

In order to be able to yield to rotary movements in the vertical direction, the slide is connected to the transition bridge by means of a hinge.

The traversing device, consisting of a carriage and roller carriage, has an elastic element for stabilization in the axial direction, for example a spring in the form of a leaf spring, through which the carriage is connected to the roller carriage. This leaf spring is able to absorb compressive forces due to its arrangement between the carriage and roller carriage. The transmission of tensile forces, such as occur when the transition is pulled together, is done by coupling the roller carriage to the carriage.

The roller carriage is guided in a box-shaped frame in which the piston-cylinder drive for the roller carriage is also arranged, the roller carriage being both castors and laterally arranged rollers for guidance in the frame. This largely prevents the roller carriage from tilting in the box-shaped frame.

In the collapsed state, the corrugated bellows is advantageously fixed to the front of the vehicle by means of a locking device consisting of a locking bar and locking latch.

To release the bolt, an actuating device, for example a piston-cylinder drive, is provided which swivels the bolt out of the bolt latch against a force, for example gravity. The bolt is held in the bolt latch by gravity; However, it is also conceivable that the bolt is held in the bolt latch by a spring, in which case the bolt is pivoted out of the bolt latch against the spring force by the piston-cylinder drive. In the latter case in particular, unintentional unlocking is impossible. In any case, however, the bolt or the bolt latch is designed so that the bolt automatically runs into the bolt latch.

In order to ensure a uniform contraction of the bellows, a tension element is arranged in the area of the roof of the bellows, which is connected at the end to the vehicle.

The traction element advantageously consists of a piston-cylinder drive arranged on the roof of the vehicle, which is connected at the end to the bellows by a flexible force transmission element, for example by a rope. The tension element is therefore only activated when the bellows is to be contracted.

To move the bellows apart, the device arranged on the roof of the bellows is not necessary, since the bellows in the retracted state has the tendency to push apart due to its own pre-tension.

The arrangement of a cable between the piston-cylinder drive and the attachment point on the bellows is necessary because a rigid connection, for example when cornering, would result in tension in the piston-cylinder drive.

1, the transition designated overall by 1 has a bellows 2, which has a coupling frame 3 at one end for connection to the opposite transition, and which is connected to the vehicle frame 4 at its other end. In the bellows 2 there is the transition bridge 5, which is designed as a link bridge and is connected on the one hand to the coupling frame 3 and on the other hand to the movement device designated overall by 6; the travel device 6 is mounted in the box-shaped frame 22 of the vehicle 1a.

The dome frame 3 can be fixed to the vehicle frame 4 by the locking device 7. The piston-cylinder drive 8 is located on the roof of the vehicle 1a, the piston 8a being connected to the coupling frame 3 by means of a cable 9.

The traversing device, designated overall by 6, can be seen in a plan view in FIG. 2. The movement device consists in detail of the roller carriage 10 and the slide 11. The slide 11 is connected here by hinges 12 to the link bridge 5 (FIG. 3) in order to be able to give way to movements of the link bridge 5 in the vertical direction. The link bridge 5 is pivoted by the pivot bearing 13 on the coupling frame 3 in order to rotate in horizontal direction, as they occur, for example, when cornering the railcar train. Since the transition bridge 5 is designed as a link bridge and is therefore also flexible in the horizontal direction, this constructive design prevents the occurrence of tension in the transition 1

The roller carriage 10 consists in particular of two parallel longitudinal beams 10a, which are connected by the cross members 10b and 10c. The carriage 11 is slidably mounted on the longitudinal beams 10a. In this case, a sliding layer 10d can be applied to the longitudinal beams 10a. To guide the carriage 11 on the roller carriage 10, the carriage has guide rollers 20 arranged laterally in the region of the inner surfaces of the longitudinal members 10a; In order to prevent the carriage 11 from lifting off the roller carriage 10, the carriage has a shoe 20a on both sides which engages under the respective longitudinal member 10a (FIG. 4).

Otherwise, the roller carriage 10 is connected to the carriage 11 by the leaf spring 19. The ends of the leaf spring 19 each abut against the bearing crossbeam 11a of the slide 11 and is received by the crossbeam 10b of the roller carriage 10 in a clamping manner at approximately the center.

The roller carriage 10 can be coupled to the carriage 11 by two coupling devices 14.

The coupling device 14 consists of a piston-cylinder drive 15, by means of which a lever 16 arranged on the roller carriage 10 can be pivoted about an axis 17 into a recess 18 arranged in the carriage 11 (FIG. 5).

The entire traversing device 6, consisting of roller carriages 10 and slides 11, is movably supported in the box-shaped frame 22 arranged on the vehicle. For this purpose, the roller carriage is provided with castors 23 and laterally arranged guide rollers 24, which have the task of preventing the roller carriage from tilting in the box-shaped frame 22 during the movement. The piston-cylinder drive 25 is arranged approximately in the center of the roller carriage 10 in the box-shaped frame 22 in the longitudinal axis. The cylinder of the piston-cylinder drive 25 is fastened in the box-shaped frame 22 to the bearing block 26. The piston 25a of the piston-cylinder drive 25 is articulated on the cross member 10a of the roller carriage 10.

The overall locking device designated 7 (FIG. 6) consists of the pivotable locking bar 27 arranged on the frame 4 of the vehicle 1a, which engages in a locking latch 28 located on the coupling frame 3. The locking head 27a is slightly curved inwards; Correspondingly, the bolt holder 28a of the bolt latch 28 is slightly bevelled on the outside in order to allow the bolt 27 to enter the bolt latch 28. To release the bolt, a piston-cylinder drive 29 arranged on the frame 4 is provided, by means of which the bolt 27 is pivoted upward out of the bolt latch 28 against gravity.

In the area of the locking device 7 is the centering device 30, consisting of a centering mandrel 31, which runs into a correspondingly designed bore 33 in the coupling frame 3.

The device works as follows:

In the connected state of two railcars, the power flow through the coupling frame 3 into the pivot bearing 13 through which the link bridge is mounted, which in turn is connected to the carriage 11 by the hinges 12. The carriage 11 is connected to the roller carriage 10 by the spring 19. The roller carriage is held in the box-shaped frame 22 by the piston-cylinder drive 25. Thrusting movements occurring when the train is traveling are thus absorbed by the spring 19.

If the transition to the frame 4 is to be used, the carriage 11 is first coupled to the roller carriage 10 by means of the two coupling devices 14 and then the roller carriage is moved into the dashed position shown in FIG. 2 by the piston-cylinder drive. This is possible because the carriage 11 is connected by the link bridge 5 to the coupling frame 3 by the pivot bearing 13. Parallel to the movement of the piston 25a of the piston-cylinder drive 25, the piston 8a of the piston-cylinder drive 8 is drawn into its cylinder, the coupling frame 3 and thus the bellows 2 also being pulled on by the cable 9 which is fastened to the coupling frame 3 the frame 4 can be used.

At the moment when the coupling frame 3 is in contact with the frame 4 of the vehicle 1 a, the bolt 27 of the locking device 7 runs into the bolt latch 28 arranged on the coupling frame 3.

Since the corrugated bellows has the tendency to diverge due to its inherent internal tension, only the force of the piston-cylinder drive 25 is required to move the corrugated bellows 2 apart in order to achieve a uniform expansion of the bellows.
