Description

The invention relates to a transition between two articulated vehicles, comprising a bellows and arranged on the inside of the bellows flexible side wall, wherein the side wall is assigned at least one end a rotatably mounted roller body, wherein the flexible side wall of the rolling body at a predetermined angle wraps around, wherein the flexible side wall is articulated end to end by a releasable connection to the rolling body.

An inner wall lining of the bellows of a transition in the form of a flexible sidewall cover may be required to protect the bellows from destruction by passengers. That is, such a side wall in the form of an inner wall panel serves as vandalism protection. In addition, however, such a side wall also has the function of visually enhancing the transition as such, in that the bellows, which is part of the transition, at least laterally covered.

In this context, a transition with an interior trim example of the DE A 3639898 known. The inner lining known from this document is characterized in the longitudinal direction of the transition seen through an inner and two outer cladding elements, wherein the inner cladding element moves when cornering of the train relative to the two outer cladding elements. Such a construction is complex and expensive. From the EP 625459 A1 is known a side wall cover, which is designed as a plate which is formed elastically resilient and curved around the vertical axis in the direction of the center of the transition. The holder for receiving the side wall cover is characterized in detail by two spaced apart from each other on the respective car bodies spring hinges, which are in communication with a part-circular, cylindrical element, wherein on the cylindrical element an elastic intermediate member made of an elastomer is arranged, which finally with the side wall cover is in communication. Here, a steel cord is provided, which contracts the two ends of the side wall cover, and on this causes a bulge of the side wall cover in the direction of the inside of the transition. This bulge ensures that when cornering the side wall actually bulges in the interior of the transition; this, however, to the extent that the clear passage width is significantly reduced in the transition.

From the German utility model DE 20 2010 014 610.0 U1 a flexible side wall cover of the aforementioned type is known, which is arranged on the inside of a bellows of a transition between two articulated vehicles, wherein the side wall cover is held by two holding devices, wherein in each case a holding device is arranged on the car bodies of a vehicle. In this case, the holding device takes the side wall cover on shortening the length of the side wall cover when cornering on rollable. That is, in contrast to the prior art according to the previously discussed EP 625459 A1 a reduction of the clear passage width of the transition does not take place when cornering. The design of this side wall cover is made in detail such that the holding device has an axis in each case, wherein the axis shows a rolling body, which receives the side wall roll-up. The rolling body is connected to the axle via a prestressed torsion spring in connection, which ensures that a shortening of the bellows on the inside of the curve, a corresponding shortening of the flexible side wall takes place, namely by the fact that the side wall rolls up accordingly on the rolling body. This reeling occurs, as already stated, by the bias of the torsion spring.

A transition between two articulated vehicles, in particular rail vehicles is characterized in detail by the previously mentioned bellows and z. B. a transitional bridge, which is spanned by the bellows tunnel-shaped. A train consisting of several vehicles is often extended or shortened to adapt to the currently existing passenger volume by connecting or disconnecting individual vehicles. Here, not only the transition so the bellows and the bridge or platform of the one vehicle must be decoupled, but also the flexible side wall.

The object underlying the invention is to provide a simple and cost-effective solution for the uncoupling of the flexible side wall of the front side of a vehicle.

To achieve the object serve the features of the characterizing part of claim 1 in conjunction with the features of the preamble. In this case, the rolling body is connected by a arranged in the region of the transition bracket with the end face of the rolling body trimmed vehicle, wherein the holder has a device for rotating the rolling body, wherein by rotating the rolling body of the rolling body can be converted into a position in which the releasable Connection is accessible to the operating personnel. That is, the detachable connection between the rolling body and flexible side wall is located in z. B. the neutral position of the flexible or elastic side wall on the side wall of the bellows facing side of the rolling body. By means of the rolling body is rotated so that the detachable connection of the transition bridge or the platform is visible and thus accessible. The neutral position is the position at which the two vehicles are in alignment with each other. It has already been pointed out that the flexible side wall is biased by the at least one torsion spring, which is part of the rolling body, under a bias that causes the flexible side wall in the decoupled state of two vehicles as well as, for. B. curls when cornering on the inside of the curve. The bias of such a torsion spring is about 600 Newton. In addition, there is the bias of the flexible sidewall which causes the sidewall to curl around itself when released. It has already been pointed out that the connection of the flexible side wall to the rolling body takes place on the rear side of the flexible side wall, ie on the side which is directly associated with the side wall of the bellows. The back of the flexible side panel is inaccessible. Insofar is through brought the device according to the invention for rotating the rolling body of the rolling bodies in a position in which the detachable connection is accessible to the operating personnel. It is clear that after the decoupling of the flexible side wall of the corresponding one vehicle, the rolling body on this one vehicle, however, the flexible side wall remains on the other vehicle. There, the end of the flexible side wall can be attached.

Advantageous features and embodiments of the invention will become apparent from the dependent claims.

Thus, it is provided according to a special feature of the invention that the flexible side wall has at both ends in each case a rolling body, which wraps around the flexible side wall by a predetermined angle. The wrap angle is advantageously about 270 °. This means that when cornering by rolling the flexible side wall of the two rolling elements a sufficient length of side wall can be provided to pass through even tight bends. On the inside of the curve, the flexible side wall rolls onto the two rolling bodies, whereas the side wall rolls on the outside of the curve of rolling bodies in each case upon rotation of the rolling elements.

The detachable connection between the flexible side wall on the one hand and the rolling body on the other hand is made according to a variant by a plurality of successively arranged screws. In particular, the flexible side wall has an end in the installed state vertically over the height of the flexible side wall extending row of holes or perforated strip, with a corresponding number of holes in the wall of the rolling body is provided to connect the two parts by screws. It is conceivable in this context, the perforated strip on the flexible side wall with a number of slots to equip, which at one end each have a substantially circular recess, and whose diameter is slightly larger than that of a screw head to pass by vertical displacement of the end of the side wall first the heads of already arranged in the rolling body screws through these circular recesses, and then move the screws with their screw shank in the area of the slots, then firmly tighten the screws. In this respect, this releasable connection is also designed in the manner of a latching connection.

For the connection of the rolling body with the end face of this rolling body associated vehicle, as already stated, a holder is provided. On the holder, the device for rotating the rolling body is advantageously arranged. The device for rotating the rolling body comprises according to a particularly advantageous feature of the invention, a clamping device which is connected by a traction means, for example in the form of a belt with the rolling body such that upon actuation of the tensioning device, the rolling body rotates, and thus the releasable connection for the operator, who is located on the bridge of the transition, is accessible to be able to release the flexible side wall of the rolling body, or to connect the flexible side wall with the rolling body after the coupling of both vehicles. It has proven particularly advantageous if the clamping device is designed as a ratchet. The ratchet can be designed as a so-called Gurtratsche, as it is also known as means for securing cargo in trucks. It is conceivable in this context, however, also form the clamping device by motor.

In order to ensure that the rolling body can be rotated so far that the detachable connection for the operating personnel, which is located on the bridge or platform of the transition, visible and thus accessible is provided according to a further feature of the invention that the traction means, and in particular the belt is arranged on the rolling body in the region of the releasable attachment. Advantageous The attachment is even slightly behind the releasable attachment between the elastic side wall and rolling body, ie the belt wraps around the rolling body by more than 270 °, so as to ensure that the detachable connection from the center of the transition is actually accessible. According to a further feature of the invention, the rolling body shows a central axis, wherein the at least one torsion spring is received by the axis. This torsion spring is supported with its one end on the axis, and with its other end on the rolling body. The bias of the torsion spring is in this case such that the flexible side wall when cornering on the rolling body up or is rolled off this. However, this also means that the rotation of the roller takes place against the force of the torsion spring. This means that the torsion spring is always biased by the tensioning device upon rotation of the rolling body. Now, if the clamping device is opened to relieve the traction means, so the rolling body would turn back immediately to its original position. In case of careless operation, the operating personnel could be injured. In this respect, it is proposed according to a further feature of the invention that the traction means of the clamping device is assigned a braking device. The braking device, which comprises, for example, an eccentric lever, is advantageously located on the holder for the rolling body. The traction means and here for example the belt runs under the eccentric of the Exenterhebels. Thus, the belt braked by returning the rolling body under the eccentric Exenterhebels can pass through pivoting of the Exenterhebels. The use of such a braking device is not only useful to run the return movement of the rolling body braked in decoupled from the rolling body side wall, but also to have done after re-connection of the side wall with the rolling body curling of the rolling body with the attached side wall braked ,

The flexible sidewall is in the Fig. 1 denoted by 1, the bellows with second bellows and side wall are part of the transition between the two vehicles 4 and 5, wherein the transition also still includes the bridge 3. Such a flexible side wall is located on each side of the bellows. The flexible side wall has on both sides in each case a holder 10 (FIG. 2ff), the roller body 15 being held by the holder 10. To connect the holder 10, which is attached to the end face of the respective vehicle, with the rolling body 15, two superimposed carriers 17 are provided, which are in communication with the central axis 18 of the rolling body.

The axis 18 shows the torsion spring 19 ( Fig. 3 ), which is supported on the one hand on the axis 18, and on the other hand connected to the rolling body.

As the representation according to Fig. 3 can further be seen, the flexible side wall at the end of a perforated strip or row of holes 20 with openings 21, wherein corresponding thereto, the rolling body 15 corresponding holes or openings 21 a, which correspond to the openings 21 of the perforated strip or row of holes. In the presentation according to Fig. 3 the perforated strip is located on the back side of the flexible side wall, that is to say in a region which is separated from the transition bridge 3 (FIG. Fig. 1 ) is not accessible. To order a flexible side wall in the position as z. Tie Fig. 2 and 3 (neutral position) is shown to be able to decouple from a rolling body to solve the transition from this one vehicle, the rolling body 15 and accordingly the flexible side wall in the direction of arrow 25 must be rotated ( Fig. 3 ). The rolling body then has a position as in Fig. 4 is shown, in which the holes 21 a are visible in the rolling body from the inside of the transition ago.

In Fig. 4b is a perforated strip 20 with openings 21 b shown, which are characterized in that they are designed as slots having a plug hole at the end, which is slightly larger than a screw head of a in the bore 21 a of the rolling body einitzenden screw 21 c. The screw heads of the screws 21 c are inserted through the plug holes, and then pull the elastic side wall in the drawing upwards, so that the screw heads reach into the region of the slot. In the presentation according to Fig. 4 the flexible side wall has already been omitted in order to make the position of the rolling body from which the side wall is to be decoupled clearer. The same position, the rolling body during the coupling process.

To now one of the two rolling elements 15, on which the flexible side wall rolls up in a position of the Fig. 2 in the Fig. 4 to be able to convict, has the holder 10 designated a traverse 11, wherein on the crossbar 11 a Gurtratsche 30 is arranged. The Gurtratsche 30 receives the designated belt 31, wherein the belt 31 is guided over a deflection 35 to the rolling body 15 around ( Fig. 3 ). Due to the deflection 35, the belt is deflected by 90 ° to the roller body 15, as is also the case Fig. 3 results. The belt wraps around the roller body 15 at an angle which is substantially greater than the angle at which the flexible side wall wraps around the roller body, that is, the flexible side wall is fixed with its end arranged hole bar 20 on the rolling body. This is to ensure that the rolling body can be twisted so far that the perforated strip 20 for uncoupling the flexible side wall of the corresponding rolling body is actually easily accessible from the transition bridge of the transition. Looking again at the Fig. 4 , so found above the Gurtratsche 30 designated 40 braking device. The braking device 40 comprises the eccentric lever 41 (FIG. Fig. 4a ), under which the belt 31 runs. By pivoting the Exenterhebels 41 of the belt is released or he is held.

Out Fig. 5 it can be seen how the flexible side wall 1 is received in the decoupled state by the holder 10 on the other rolling body. In this case, the carrier 17 each have a tab 27, each having an inwardly directed pin 28, wherein the pins 28 engage in holes 21 of the perforated strip 20. Due to the residual stress of the flexible side wall, the flexible side wall remains adjacent to the tab 27th
