Railway freight wagons. - Järnvägsgodsvagn.

The present invention relates to a railway wagon having a wheeled carrier with a substantially flat load carrier and longitudinal-5 brackets formed between suspension wheels to form a hinged support, with the cargo space being delimited by two moles and by side walls formed by a pivotable and movable sliding wall member or delimited in each case by two roof and side wall raised, pivotable or full-wall sliding or full-wall sliding portions which are retracted from the upper end of the receiving member and at the longitudinal end of the trolley toward the central part of the wagon, there are second traction receiving means for holding the pusher or 15 full-wall sections on the lower chassis.

Such rail freight wagons, as a 2-axis and 4-axle embodiment, form standard freight wagons that are not allowed to get wet during transport. Due to the ever increasing demands of the users regarding the lightness of the structures, the larger load spaces and the lower load surfaces, there is a need to apply the forces exerted in the rail traffic to the supporting structure for the whole carriage basket and thus the parts to be opened for loading and unloading.

A side wall with sliding wall sections for rail freight wagons is known from DE-A-23 38 530, in which, in the case of a butt stroke, horizontal forces are applied from the end walls to the outer longitudinal supports of the wagon base. In this case, the sidewall of the rail wagon is formed by the end columns, the upper belt, the longitudinal brackets on the outside of the trolley and the midmost columns, and the closed columns by means of the foremost 2 107138 surfaces at least in their upper and lower portions, wherein the rectangularly extending surfaces have abutment surfaces at least in their upper and lower portions and wherein the pusher wall portions have opposed or abutment surfaces in the opposed longitudinal portions of the abutment surfaces 5 is provided with a stop surface provided with clearance for head-posts or center-posts in front of the counter surfaces. This design of the corner and center pillars or push-in wall sections ensures that the free rotation of the carriage basket within certain limits is not prevented by the push-in wall sections. As the carriage basket is rotated, the pushing wall portions 10 slide smoothly along their sliding surfaces along the side wall mesh. If, on the other hand, the bullet stroke exhibits angular displacement of the sidewall body in the longitudinal direction of the carriage, this angular displacement may only continue until the stops at the vertical longitudinal end of the pushing wall member rest against the abutment surfaces of the foreheads or center columns. Thereafter, the sidewall frame 15 is angularly rigid and longitudinal forces are applied diagonally from the upper end wall ends via sliding wall sections to the brackets outside the carriage. However, in this construction, the forces acting on the badly loaded front wall during the butt stroke are only applied through the entire roof section to the opposing ot-20 wall and then diagonally through the respective pushing wall sections through the respective pushing wall sections. Thus, only the longitudinal end pushing wall portions of the wagon are stressed by the movement in the cart.

This adversely affects their construction. In addition, the buckling stability 25 of the sliding wall sections, which have become thinner as the structures are lighter, is no longer sufficient to conduct all the forces involved in the collision to the carriage.

DE-OS 33 12 001 further discloses a rail wagon with end walls and a fixedly arranged middle-level, substantially flat load-bearing base and cargo-cover, one-plane guards that are divided and provided at the top with movable and displaceable positions for pushing from the closed position. pivotable outward, • · each cargo cover between the cargo end wall and the center staircase is closed 3 107138 in the dry position locked at its longitudinal end face-to-face with the head wall, and on the longitudinal sides lower near the the longitudinal ends 5 being lowered by ramps in the direction of the front wall and standing in relation to the carriage chassis so that it is prevented from rising. In this embodiment, the loading pressure acting on the front walls is, in the case of a bullet stroke, largely supplied through the guards to the railcar trolley chassis by means of a traction force applied to the trolley chassis via the guards. The front wall can then be lighter 0 and its connection to the undercarriage can be simplified. However, it is disadvantageous in this embodiment that the second requirement for all railway carriages, namely lifting the railway carriage in the loaded space to the ends by means of lifting devices under the carriage, is to cause considerable overload of the carriage because the car body 15 is not usable. In said publication, the shields, due to their attachment to the front wall and to the trolley base, are not capable of providing relief of the trolley base.

Starting from this latter state of the art, it is an object of the invention 20 to provide a rail freight wagon of the kind mentioned above with the ability to retract the load-limiting push-wall or full-wall portions of the rail-wagon. a closed wagon to conduct the horizontal and vertical forces that may occur on the one hand on the rail and on the other hand when lifting the freight wagon from its running gear.

According to the invention, this task is solved by pushing or thrusting. · The second retaining means arranged on the lower longitudinal edge of the wall sections have a retaining loop which, in order to transmit tensile and clamping forces, co-operates with a pin fixed to the carriage base. By means of the construction 30 of this invention, both the horizontal longitudinal forces acting on the front walls are directly connected to the trolley via the vertical parts of the pushing or full-wall sections acting as a pull strap, as well as the lifting which, by virtue of its fish-like structure, must be regarded as uncritical of bending. According to the invention, the fastening of the pushing or full wall sections with the end wall or the carriage base is provided with a longitudinal clearance. This longitudinal clearance of the 5 anchorages ensures that the rotation of the trolley body required for good traction properties and the use of sliding wall sections under various loading conditions are not prevented.

In accordance with the invention, it is provided that connecting slabs or cam are provided with the sliding or full wall sections and the sliding wall or full wall sections and the slab or cam with the sliding wall or full wall sections and the trolley or center column or center portal.

In the following, the details of the invention will be explained in more detail with reference to the drawings, by way of example.
