BACKGROUND OF THE INVENTION The present invention relates to a sliding wall arrangement, in particular for roof rail freight wagons, in which sliding wall sections in a common flat position when closed can be mounted on a lower running rail with a handwheel sliding wall portions are slidably movable between the intermediate divider and the other sliding portion.

When covered rail freight wagons are closed, the sliding wall sections are in common plane. In such a known solution (see, for example, DE-1 116 260), the side wall is divided by an intermediate column transverse to the car, and as this intermediate column connects the outer longitudinal frame of the chassis to the upper longitudinal girdle of the roof. and tilting mechanisms. Each sidewall in this arrangement has two sliding wall portions which can be slid in the upper longitudinal belt, or in the sliding wall portion in the closed position. The disadvantage of this arrangement is that it is insufficiently raised at the end of the car at the initial displacement of the sliding wall portion at the time of opening, thereby preventing the load from being supported by the sliding wall portions from opening.

It is further known from DE-2 103 985 that a single straight and non-fitting running rail is provided in the upper longitudinal ridge of the sidewall of a rail freight wagon, in which the outer surface of the chassis outer rail serves as a running surface for the sliding wall sections. it holds the swiveling parts of the tread and each slide part retains the running surface of the other part. In this configuration, the lifting device, which is parallel to the floor and is connected to the actuator by its axis, is pivotable in the transverse direction, in the vicinity of the outer railings. The sliding door sections are supported by support arms with rollers pivoting about a vertical axis at the free ends, and guides located on the outer rails at the bottom of the spine plate and lower guides. Each sliding wall section is provided with at least two rollers or guide forks embedded in the upper end of the sidewall frame. They are pivotally mounted on axles or pins that can be swiveled by the operating link. The sliding wall portions hold the running rollers and guide cams cooperating with the rollers and the forks, which are pivotally mounted on the support arms. However, the disadvantage of this known sliding wall arrangement is that the actuator elements in the body are too large, which makes it very expensive to manufacture and install.

From practice and further publications, a number of other sliding wall arrangements are known for closed rail freight wagons. All these conventional solutions have the common drawback that the sliding wall portions are only displaced outwardly from the closed position to their offset position, or only slightly elevated outwards relative to the longitudinal axis of the railway wagon. In modem freight wagons, the roof structure is a relatively thin building block to take full advantage of the horizontal loading and unloading of the vehicle defined by the space gauge. The sliding wall portions, which are curved inwardly at the upper section of the section profile, at the same time partially take over the function of the roof. The pallets required for loading the goods can be pushed outward in the upper area and leaned against the inner curved wall of the sliding part. However, when opening sliding walls only that are tilted outwards horizontally, there is a risk that the sliding wall sections in the upper area will not be able to separate themselves from the load and thus have problems with opening sliding wall sections.

Further, all known sliding wall arrangements have the common disadvantage that their actuators are extremely expensive and, in addition, require complicated and expensive power transmission structures in the roof area.

Based on the state of the art, it is an object of the present invention to overcome the above shortcomings, that is, to provide an improved sliding wall arrangement where the handling of sliding wall portions is significantly simpler than known solutions and the number of actuators is much smaller.

Thus, in order to solve this problem, we started with a sliding wall arrangement of the type described in the introduction, which is mainly used for covered rail freight wagons, in which the sliding wall sections in a common flat position are closed by a handwheel and a lateral , the sliding wall portions in the closed position are movably displaceable longitudinally between the intermediate manifold and the other sliding wall portion by means of running rollers. It is an object of the present invention that the sliding wall portions are guided on the roof structure by appropriate wires when moving from the closing plane to the offset plane and are inclined upwards and outwards. By this measure, it has been achieved that the lifting and moving out of the roof wall portions according to the invention cannot be disturbed by the conveyor contacting them, the upper curved section of the sliding wall or the horizontal section of the sliding wall.

It is desirable to have a design in which the wires are formed with outwardly facing roof side walls in the direction of the center length of the trolley, which are inclined relative to the center length of the roof. Further, the sliding wall portions, when in their closed position, are supported directly or through braces on the sidewalls of the roof structure. The sidewalls, in the offset position of the sidewall portions, form the conductors of the sidewall portions toward the center of the wagon length. This design achieves a very simple and economical structure. At the same time, the roof sides serve as a guide for the sliding part against the center of the wagon length. The number of structural elements was reduced to a minimum.

According to a further feature of the invention, it is desirable to have an embodiment in which the outer guides transverse to the center of the carriage are guides and / or rails fixed on the roof structure, spaced from and parallel to the side walls. Further, the sliding wall portions rest in their closed position outwardly on the rails, while in their offset position they are guided outward on the guide rails. The ridges are thus connected to the roof sides with the sliding wall in closed position and to the sliding wall in closed position. With this arrangement, the number of structural members required is further reduced.

The invention is again a further preferred example. In its embodiment, the roof structure is provided with a profiled sealing plate on both sides longitudinally in the longitudinal direction of the carriage, provided with a rubber band on one side and vertically displaceable. In the closed position of the sliding wall portions, the sealing plates are by their own weight resting on their free length at the top of the sliding wall portions, but in the offset position of the sliding wall portions are thereby lifted and the sliding wall portions are sealingly guided. This arrangement with a rubber-bearing sealing element provides good sealing for the sliding wall sections in the roof area, while ensuring optimal utilization of the rail gauge profile through a flat, movable construction.

The invention will now be described in more detail with reference to the accompanying drawings, in which an exemplary embodiment of the present invention is illustrated. In the drawing:

The freight wagon shown in Figure 1 consists essentially of a landing gear 1, a chassis 2, front walls 3, a roof structure 4 and two sliding wall sections 5 on each side. Each of the sliding wall portions 5, when in its closed position, is flush with the longitudinal side of the chassis 2, and at the top is sealed against the roof structure 4. The longitudinal ends of the sliding wall portion 5 lie in a closed position on the front wall 3 and on the partition column 6. Each of the sliding wall portions 5 has a cross-sectional shape in accordance with the rail gauge profile, i.e. the lower part has the sliding wall part 5 in a vertical plane and the upper part has an inwardly curved configuration according to the gauge profile.

The chassis 2 is provided with external longitudinal brackets 7 according to the conventional design. The roof structure 4 which closes the front walls 3 is only a narrow, box-shaped, open-bottomed structure in the present case, which is reinforced with cross rails 8 inside.

In order to displace the sliding wall portions 5, they are provided at the bottom with running rollers 9 fixed near their longitudinal ends, at each end of which each running roller 10 is rotatably arranged about a horizontal axis. The running rollers 10 are rolled down on the running rails 11 in the offset position of the sliding wall portions 5, which are rigidly fixed on the outside of the outer longitudinal rails 7 of the chassis 2. All running rails in this case are straight and run uninterrupted from one end wall to the other.

Each of the sliding wall portions 5 is raised and tilted outward to move it from its lowered position on the heating rails 10 in the closed position on all heating rails. This lifting and tilting of the sliding wall section 5 is effected by an actuating shaft 12 which is pivotally mounted in the longitudinal direction 7 of the outer longitudinal rails of the chassis 2 and is provided with a support rail 13 for each running roller 10 of the sliding wall sections. In order to rotate the actuator shaft 12, each sliding wall portion 5 is provided with a handwheel 14 on its associated front wall 3 which rotates the actuator shaft 12 through a gear 15 and a pivot 16. However, the handwheel 14, the gearbox 15 and the linkage 16 are not a direct object of the invention.

In addition to each sliding wall portion 5, a roller foot 20 is provided near its longitudinal end, and at its free end is provided with a guide roller 21 which is pivotable about an oblique axis relative to the longitudinal axis of the carriage. The roof structure 4 is provided on its long sides with flat side walls 4a inclined with respect to the longitudinal axis of the carriage. The roof structure 4 is bent horizontally outwardly at the lower ends of its side walls 4a and vertically upwards at its free ends. On the side walls 4a of the roof structure 4 guide rails 22 are arranged parallel to the side walls 4a. These guide rails 22 in the region receiving the guide rollers 21 of the sliding wall portions 5 in the closed position are interrupted, and in the plane of the guide rails 22 a ridge 23 is arranged which is parallel to the side walls 4a of the roof structure. located in a well-formed recess in the area of the roller foot.

In the closed position of the sliding wall portions 5, the sliding wall portions 5 are disposed below the actuator shaft 12, the bottom heating rail and the running rollers 10, and they lie flat on the outer longitudinal brackets 7 of the chassis 2. Above, the sliding wall portions 5 with their closure profile 5a fit in a maze-like manner to the side walls 4a vertically and water3

EN 221 115 Β1 curved flatly into the longitudinal edges. The sliding wall portions 5 rest on the roof structure 4 on the guide rollers 21, the roller legs 20, on the one hand, and on the side walls 4a of the roof structure 4, on the other. Transverse to the longitudinal axis of the carriage, horizontally outwardly against the lifting of the sliding wall portions 5, the sliding wall portions 5 are secured at the top with the guide rollers 21 resting on the ridges 23 and at the lower end of the

To move the sliding wall portions 5 out of the locking position, the handwheel 14 rotates the actuator shaft 12 through the gearbox 15 and the linkage 16, thereby raising the support rail 13 in the offset position and tilting it outward. Meanwhile, the running rollers 10 are raised and tilted from the support rail 13 to the all running track. At the top, each sliding wall portion 5 is rolled through its guide roller 21 on the sidewall 4a of the roof structure 4 and the ridges 23, and are led obliquely upwards and outwards. In this raised and tilted position, the sliding wall portions 5 can be moved to a locking position at the bottom under the running rails and at the top on the side walls 4a and guide rails 22. With this arrangement, no additional guide rollers, guide rails or other actuators are required in the roof area and the upper sliding wall area.

The roof structure 4 is provided with a sealing plate 25 on each side, provided with rubber bands 26 on one side and arranged vertically. The sealing plates 25, when in the closed position of the sliding wall portions 5, rest on their free longitudinal sides on the sliding wall portions 5 due to their weight. In the offset position of the sliding wall portions 5, the sealing plates 25 are lifted by the sliding wall portions 5 themselves, after which the sliding wall portions 5 to be moved are slidably guided by the sealing plates 25.
