DE3514978A1 - Intercommunicating gangway for rail vehicles coupled to one another, and method of installation - Google Patents

Abstract

The subject of the invention is, on the one hand, an intercommunicating gangway for rail vehicles which are coupled to one another and whose deformable sleeve, which is held at the two ends in frames, forms a tube which is closed on all sides in the longitudinal direction of the vehicle and, on the other hand, a method for installing an intercommunicating gangway of this kind in the coupled state. For this purpose, the sleeve is constructed as a tube which is closed on all sides and is constructed in a cantilevered fashion and is held at its two ends in divided frames. By virtue of this design, it is possible to install the intercommunicating gangway from the inside.

Transition protection for rail vehicles coupled to one another

and method of installation

The invention relates to a transition protection for rail vehicles coupled to one another, according to the features of Preamble of claim 1 and a method for installing the transition protection in vehicles in the coupled state.

In the passenger train traffic, the transfer from car to car is predominantly Transition devices consisting of transition bridge and transition protection are used. Basis of the possibility of Überwechseleins are accessible transition bridges that bridge the space between successive carriages or vehicle sections cover and for safety and increased comfort from one Transitional protection, for example consisting of a displaceable, elastically deformable cover and / or a displaceable rigid one Enveloping elements, is surrounded. The UlC bulge transition exists only from the rubber beads arranged around the transfer opening and is neither tight nor does it close the gap between the individual cars. It offers practically no protection against noise pollution and prevents the ingress of drafts, Dirt and cold only very poor. This is increasingly evident at higher travel speeds. Also the with increasing travel speed with higher intensity

pressure surges that occur when trains meet and travel through tunnels can enter the transition area unhindered.

These deficiencies are largely eliminated by transitional protection after the DE-PS 10 57 639. This transition is in its preferred embodiment by the in a vertical vehicle transverse plane formed split tube and has two halves symmetrical to the parting plane. The two halves of the transition protection are each suspended with the end frame on the associated end of the car. It should also be possible to use the transition protection between to make two vehicles in one piece in its entirety and for this purpose a tubular shaped mat between two facing ends of the consecutive Arrange vehicles. However, it turns out to be practically impossible to make such a transition between two coupled To spend vehicles and to assemble, especially if the decanted UIC bead transition in the form of the well-known rubber beads should or must remain on the vehicles. Regardless of this, this transitional protection protrudes into the Bern area, so that may no longer be stepped between the vehicles for the purpose of assembly. The division of the transitional protection into several Wall parts create additional connection, sealing and Assembly problems.

The object of the present invention is to create a device to be mounted from the inside in coupled vehicles and this Requirement of specially adapted transitional protection as well as a

To show procedures for its assembly, in particular while maintaining the UlC bead transition at the vehicle ends, both while improving the state of the art and largely avoiding serious disadvantages thereof.

The solution to this problem is described in claims 1 and 2 .

Further advantageous embodiments of the invention Transition protection and the method for its assembly are described in claims 3-8.

The invention will now be described with reference to the drawing, which represents a non-restrictive embodiment. It shows

Fig. 1 shows an embodiment of the invention, when fitted on the end of the vehicle with UIC Wulstübergang in front view;

2 shows an embodiment of the invention, when fitted on the end of the vehicle with UIC Wulstübergang in side view.

3 shows an embodiment of the invention in the installed state at the end of the vehicle with UlC bead transition in plan view.

The transition protection 1 consists of an elastic deformable one extending in the vehicle longitudinal direction and to the respective Ends by means of frame 2 enclosed casing 3. This casing forms a tube 4 closed on all sides, is preferably is formed in one piece and is held in one-piece or multi-piece frame 2 at the ends. The embodiment shows one Frame 2, which consists of an upper frame part 2a, a lower frame part 2b and the side frame parts 2c and 2d. The end faces of the tube 4 are completely encompassed by the frame 2. However, frames 2 can also be used, which form the end faces the tube 4 border only partially. The frames 2 are self-supporting at the vehicle ends 5 facing each other not shown screws 6 or quick release elements attached. The frame 2 includes the transition bridge 8 between the vehicles and is the contour of the portal 9 of the vehicle end 5 adapted. A safety lock 10 prevents the vehicles from being uncoupled before the transition protection 1 is removed. The safety lock 10 is for hook couplings 11 as a mechanical locking stop for the rotary movement of the toggle 11a Hook coupling 11 is formed. The distance between the underside of the tube 4 or an additional locking stop and the axis of rotation of the toggle 11a is designed to be less than the length of the toggle 11a.

For installing the transition protection in rail vehicles in the coupled The ring 4 provided with the upper frame part 2a and the lower frame part 2b is in the state before it is brought into the Vehicle interior compressed lengthways. Taking advantage

the twistability of the tube 4 with attached frame parts 2a and 2b, the transition protection 1 is brought from the inside into the transition area between the vehicles. After folding up the Transition bridges 8 are the upper and lower frame parts 2a and 2b at the end of the vehicle 5 by means of screws 6 or quick release elements 7 attached. After the transition bridge 8 has been folded down, the tube 4 comprises the same. Side frame part " 2c and 2d create a largely tight connection between the end of the vehicle and transition protection 1. The division of the frame 2 is depending on the free space available for moving the transition protection 1 into the crossover area at the end of the vehicle 6 and to adapt to the installation conditions, so that installation while retaining the UlC bead transition 12 in the form the rubber beads 12a, 12b, 12c is possible and takes on the function of an internal transition protection.
