Description

Australian Patents Act 1990 - Regulation 3.2 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title Coach body of a rail vehicle with a gangway half The following statement is a full description of this invention, including the best method of performing it known to me/us: P1/00/0 I la The invention relates to a coach body of a rail vehicle with a gangway half of a gangway for 5 connection with the gangway half of a gangway of the coach body of a neighboring vehicle. Rail vehicles of the type mentioned above are known; the disposition of respectively one gangway half on the front side of a coach body of a rail vehicle serves to couple this vehicle with any other vehicles of similar type. In this respect, as has already been explained, each 0 coach body of such a vehicle has a gangway half on its front side, the gangway half forming the gangway together with the gangway half of the neighboring vehicle. Such a gangway comprises a bellows, the gangway bridge being enclosed by the bellows in the form of a box. The bridge and the bellows that form the gangway allow people from 5 crossing from one vehicle into the other vehicle without being exposed to climatic conditions. In this context, a gangway half is known from the prior art that has a coupling frame on its free front side for coupling with the coupling frame of the neighboring gangway half. A rectangular circumferential tunnel-shaped frame is attached to the coupling frame, a box !0 shaped circumferential bellows element being attached to the frame in the direction of the front side of the vehicle. In the area of the gangway half, the coach body has a setback on its front side that is circumferential in the front side of the vehicle. A setback is to be understood as an offset that extends from the outer front side of the coach body to a drawn-in front side of the coach body, a door to the coach body being provided in the area of the drawn-in front side 25 of the setback. The bellows-type element made of an elastomeric material is configured in such a manner that in the area of the setback of the front side of the vehicle, it forms a type of drawn-in loop, i.e. a loop-type draw-in, that is to say that the bellows-shaped element first extends from the frame in the direction of the inside of the vehicle and is then led back in the area of the drawn-in front side of the setback at an angle of approximately 180* and disposed 30 on the lateral wall of the setback. Due to this bellows-type element that is provided at the gangway half of each coach body of a vehicle, the individual vehicles of a train that are articulately connected to each other are able to follow travel motions, such as more specifically rolling, pitching, bending and offset motions, which occur during travel. The 2 rolling motions occur when two vehicles of a train articulately connected to each other are rotated relative to each other, while bending motions occur when the vehicles of a train travel around a bend. Pitching motions occur when two vehicles articulately connected to each other travel through a hollow or over a crest, while offset motions occur when the vehicles that are 5 articulately connected to each other travel over an S-shaped railway switch. The gangway between two vehicles articulately connected to each other must be able to follow all these motion types. Now it has turned out that considerable amounts of dirt accumulate in the area of the drawn-in 0 bellows element, more specifically in the roof area. Since the surfaces of the bellows element get in contact with each other, more specifically in the area of the drawing-in, i.e. of the redirection at 180*, during all kinds of travel motions and rub against each other, the consequence is a relatively important wear. The wear is more specifically noticeable in the area of the roof in form of a frayed bellows element. But also the side walls of the bellows 5 element are subjected to wear. Therefore, the object underlying the invention is to find a remedy for this. In this respect, it is proposed that for reducing wear in a coach body of a rail vehicle with a !0 gangway half of a gangway for connection to the gangway half of a gangway of the coach body of a neighboring vehicle, the coach body has an adapter frame disposed on its front side in the area of a setback for receiving a bellows half of a gangway. From this, it is clear that the connection of the bellows half no longer occurs in the area of the setback on the front side of the coach body, but rather directly on the front side, i.e. the outer front side wall of the 25 coach body. In addition, the gangway is no longer achieved by a bellows-type element in connection with a tunnel-type circumferential box like in the prior art, but rather by a bellows half disposed on the front side of the adapter, such a bellows half being formed by several bellows-type elements, more specifically folding or corrugated bellows-type elements. 30 Advantageous features and embodiments of the invention can be gathered from the sub claims.

3 It is thus more specifically provided, that the adapter frame has a screw-on frame that is substantially flush with the front wall of the coach body of the vehicle and advantageously runs substantially parallel to the front side of the coach body. From this, it becomes clear that the actual front wall of the vehicle is broadened in the area of the setback, so that mounting a 5 bellows half, the measurements of which correspond approximately to the original gangway half, is possible. This means that when a gangway half according to the prior art is exchanged with a gangway half according to the invention, the bridge can remain in its original state, since the width of the bellows half and also its height does not change as compared to the tunnel-type frame known from the prior art, to which the coupling frame connects on the front 10 side of the neighboring vehicle. In detail, it is provided with respect to the adapter frame that it has three circumferential gate shaped sidewalls, which run at an angle relative to the longitudinal axis of the coach body and which, as a sidewall frame, define the lateral closure of the coach body in the area of the 15 setback. Together with the screw-on frame, the sidewall frame forms the adapter frame. The sidewalls of the sidewall frame itself are more specifically configured in steps, the cross section of the sidewalls being configured so that it runs outward from the inside, the sidewalls, as a cover of the setback, consequently also having a stepped form in the broadest sense. 20 A circumferential series of bores with weld nuts are preferably provided for fastening the bellows half on the screw-on frame of the adapter frame. The assembly of the adapter frame in the area of the front side of the coach body, i.e. in the area of the setback of the coach body, occurs by way of angle profiles that are connected with the coach body on the one hand and 25 with the adapter frame on the other hand. According to a particularly advantageous feature, it is provided that the adapter frame is configured in three parts, the three parts of the adapter frame being separately attachable to the coach body, namely laterally and in the roof area. In the floor area, it is sufficient to 30 arrange a screw-on rail for the bellows half. In this respect, the adapter frame does not extend over the floor area. The advantageous of this is a simplified transport; a rectangular, circumferential, gate-shaped frame takes up substantially more space during transport than is the case with three individual parts that are subsequently assembled into a frame.

4 In the following, the prior art as well as the invention are further described based on the drawings. In the drawings: 5 Fig. I shows the prior art in a sectional view from above; Fig. 2 shows a perspective view of the front side of the coach body with the adapter frame; 0 Fig. 3 shows a section according to line III - III from fig. 2; Fig. 4 shows the bellows half in the state in which it is screwed onto the adapter frame, wherein the bridge plates have been left out for a better overview. 5 The prior art can be gathered from fig. 1. Hereby, the coach body is labeled I, the bellows element is labeled 2, the frame, which extends on the bellows type element in the direction of the neighboring coach, is labeled 3 and the coupling frame disposed on the front side on the frame is labeled 4. The coach body labeled I has a circumferential gate-shaped setback 6 that, with a lateral wall 6a and a front wall 6b, is offset from the front wall I a of the coach body I .0 in the manner of an offset. In the area of the setback, the bellows element 2 forms a loop shaped draw-in 2a, i.e. the bellows element 2 is angled by 180' in the area of the draw-in 2a and runs with its one end on the lateral wall 6a where it is fastened on the coach body in the area of the front wall Ia. The two opposing sides of the bellows element 2 in the area of the draw-in 2a can get in contact with each other in the area of the side wall and also more 25 specifically in the roof area, wherein when dirt accumulates in this draw-in 2a, which is more specifically the case in the roof area, the two opposing parts of the bellows-type element rub against each other in the manner of sandpaper and the bellows element is submitted to increased wear in this area. On the other hand, upon looking at the invention such as it is shown in figures 2 to 4, the front 30 wall 21 of the coach body 20 can be immediately seen in the perspective representation according to figure 2, wherein the setback 6 is visible on the front side 21 of the coach body. The setback 6 is covered by the adapter frame 30. The adapter frame 30 comprises a sidewall frame 31 with three sidewalls 31 a, 31 b, onto which the individual screw-on frame elements 5 33a, 33b of the screw-on frame 32 are attached. The sidewall frame is merely located in the area of the lateral wall of the setback and in the roof area but not in the floor area. The screw on frame element 33c in the floor area is screwed directly on the coach body thus resulting in the uniformly circumferential screw-on frame 32 as shown in figure 2. 5 The cross-section of the sidewall frame 31 is configured in steps, as can also be seen in fig. 2, and runs outward from the inside, the screw-on frame elements 33a and 33b being connected to the sidewall frame 31 at a right angle. The screw-on frame elements 33a, 33b and 33c run in one plane with the front wall 31 of the coach body and are preferably flush with the front .0 wall of the coach body. As can be seen in figure 3, the adapter frame 30 is connected to the coach body in the area of the setback 6 by way of angle 37. The mounting of the bellows half 40 to the screw-on frame 32 can be gathered from figure 4. The bellows half 40 is configured as a corrugated bellows and has a coupling frame 42 on the 15 front side for detachable connection with the coupling frame of the neighboring bellows half when coupling two vehicles. The bellows half 40 moreover has a frame 43 that is connected to the screw-on frame 32 by way of screws (not shown). The bridge plates that form the gangway are not shown in fig. 4.
