Innovation? Kit to bridge the gap between

two articulated vehicles

Description;

transition bellows that are between articulated vehicles are arranged and tubularly surround a transition bridge to allow people to move between the two vehicles in a protected manner to enable are known. For reasons of possible assembly and disassembly, the tubes formed from the bellows are in the area of the lower wall often divided by a longitudinal slot. It is thus possible to guide the bellows around the transition bridge during assembly and disassembly.

Bellows of the type mentioned tend to sag in the area of the bellows base. This is usually prevented by the fact that expander cables are stretched between the articulated vehicles, which form the bellows prevent sagging without hindering the mobility of the vehicles against each other and the bellows. This solution can only be used if it is sufficient There is space under the swivel joint. When the expanders in modern articulated slide trains must be moved further than 250 m from the center of this vehicle, the expanders are very quickly due to the excessive expansion that takes place this place arises, destroyed. In addition, the center of the highest weight is then no support given.

On the other hand, the mentioned longitudinal slot is closed for the operating state otherwise the bad weather, blown up impurities, snow and water would enter the interior of the bellows through the slot. For this purpose, the bellows edges must be designed accordingly and detachable from one another be connectable.

This solution, which is common today, is thus expensive and with regard to the Operational safety can be improved and the task of innovation is to provide a to show effective as well as structurally simpler and thus cheaper and less failure-prone solution.

To solve the task, the innovation is based on a bridging kit zürn the space between two articulated vehicles with a tubular bellows with connecting frame Fasten the bellows to the facing vehicle front sides, with expanders in the area of the bellows base to hold the base of the installed bellows between the two end frames, and preferably a longitudinal slot in the area of the bellows base, which is to be covered.

To solve the problem it is proposed with the innovation that as an expander an elastic band, covering the possibly existing longitudinal slot of the bellows, is clamped between the connecting frame, the longitudinal elasticity of which corresponds to the longitudinal deformability of the bellows and which runs horizontally when installed. Instead of the expander cables of the known solutions, an elastic band is used according to the invention.

The elastic band proposed as part of the kit according to the innovation

prevents the built-in bellows from sagging in the area of the bellows base, The elasticity of the elastic band is dimensioned so that the band can perform this function can take over. On the other hand, due to the width of the belt, one is essential A more reliable component than the previously used expander cable are. The elastic band can also be used for covering at the same time an existing longitudinal slot can be used by placing it in its area of influence folds down the bellows folds without damaging them and thus a sealing effect is possible. In this case, the band has the dual function of tensioning the bellows and the bellows seal and there is a particularly simple arrangement.

In a further embodiment of the innovation, the elastic band is at both ends each held in a retaining bar, which is provided with connections for fixing to one of the lead frames. This turns the tape into an assembly designed, which can be assigned to the rest of the bellows easily and without the use of large tools. This is particularly the case when the retaining strips are provided with a handle each in an even further embodiment of the innovation for easier handling.

Instead of the lead frame, the tape according to the innovation can also -like the Bellows with the connecting frame are attached directly to the vehicle ends.

The innovation is explained below with reference to the drawing. In the drawing demonstrate

2 shows the elastic tension band provided for the new kit in perspective and

Fig. 3 is an exploded view of the lower bellows area with built-in, according to the innovation, elastic band.

Two vehicles are articulated, only the one in front Vehicle 1 is shown. The articulated connection is not shown because it is not essential for the innovation. A horizontal bridge 2 is arranged between the vehicles 1 in order to transfer from one to the other Enable vehicle. To this change from bad weather, To enable the wind and the like unhindered, is the transition bridge 2 surrounded by a bellows 3 known per se. At its ends, the bellows 3 is provided with a connecting frame, of which only the vehicle 1 associated frame 4 is shown. With this frame, the bellows 3 is to be attached to the mutually facing end faces 5 of the vehicles 1.

To facilitate the assembly and disassembly of the bellows 3, it is in the Mitfcs its bottom slotted lengthways. The longitudinal slot 6 is with turnbuckles 7, which together with tension cables can also be used to hold the bellows on the vehicles.

The bellows base is usually sagged by two expander cables 8, 9 prevented that are passed through eyelets 10 of the bellows and when installed Bellows can be hung on the connecting frame 4 or directly on the vehicles 1. This solution has the disadvantages mentioned at the beginning. It requires enough Space, is subject to the risk of overstretching and just does not support that Center of the bellows base.

Much better results can be achieved if, according to the innovation, the two Expander cables 8, 9 are replaced by one each, or preferably by an elastic band 11 as shown in FIG.

The elastic band 11 or the two elastic bands can by accordingly Feeled through large-sized guides on the outside or inside of the bellows will. The large area leads to a much lesser extent to great punctual stress, the arrangement becomes significantly more reliable than the solution with two expander cables. Basically it is intended that the The band 11 acting as an elastic base plate is arranged under the bellows base, it rests on the belt and there are no additional guides under the bellows base, Tabs or the like for the band 11 are provided.

The elastic band 11 is held at both ends in a holding bar 12 or 13, have the holes 14 to be connected to the lead frame 4 so that the kit can be installed in its entirety, or it can be the retaining strips 12, 13 like the connection frame 4 are attached directly to the vehicle ends, so that the two parts of the kit - bellows and elastic band - are independent can be installed from each other. Each retaining bar is for easier handling provided with a handle 15 or 16.

The elasticity of the or each elastic band 11 is dimensioned so that the Movements of the bellows, in particular the longitudinal movements of the bellows, are at most insignificant are obstructed, but the bottom of the bellows is prevented from sagging, i.e. when installed the belt or each belt runs horizontally. The bellows bands leave the bellows folds when installed in the willow, like the Expanderxabel 9,10 are built in, essentially unaffected. However, it is only an elastic one

Band arranged in the area of the longitudinal slot and on the outer side of the bellows, see above the elastic band turns the bellows folds and provides additional support a sealing effect that prevents rain, snow, dirt and wind from penetrating into the interior of the bellows. For a diagonally split bellows, both halves of which are held together by the frame 4 corresponding frame, the band 11 can also be provided with a central web 17 in which the band with the can be connected to both middle frames. Corresponds functionally to eyelets 10 Guides for the elastic band according to the innovation can be omitted, in particular if the band is not arranged on the bellows base and this rests on it.

According to FIG. 3, bellows frames are denoted by 18, 19 and the elastic band 11 is with its retaining bar 13 using a shim bar 20 on the end frame 18 fastened with screws 21, while the tape 11 is fastened to the other end frame 19 with the retaining strip 12 or the central web 17, depending on or the bellows 3 is arranged undivided or divided transversely between two vehicle members is.
