Title of the invention

Front wall section for railroad freight cars

Field of application of the invention

Bulkhead section for railroad bulkhead sections, "in which the end walls are firmly connected to the side walls by welding.

Characteristic of the "known technical solution

There are front and side walls "known, the sheets have a bulge outward in these embodiments, the bulged front and side panels are connected by straight corner pillars» The straight corner pillars form with the head piece and the upper boundary of the end wall on the curved end wall sheet a shear-stiff The upper boundary profiles of the front wall and the straight corner columns are mainly parallel hollow or rolled sections <>

In these end walls, the bulge of the end wall panel mainly serves to increase the Blechbeulsteifigkeit, d. h * the reduction in the size of the bulge surfaces and is carried out at a relatively low height.

The salient part of this end wall design is that the front end panels, the upper limit beams, the head pieces and the relatively small bulged forehead. wall panels at the ends of the car resulting shear-resistant Sche.i-

ben increase the Yerwindungssteifigkeit the car body significantly and thus reduce the derailment of the car in track distortions »

Due to the low bulging of the end wall panels occur high the upper frame burdening vertical output forces that require a relatively material-intensive execution thereof ».

Another disadvantage is the unused maximum expansion of the loading volume due to the low bulge.

Object of the invention

The aim of the invention is to reduce the torsional stiffness of the car body while reducing the material and labor costs for the production of the end walls and increase the loading volume while maintaining the external JPahrzeugabmessungen.

Explanation of the essence of the invention

The invention has for its object to reduce the torsional stiffness of the car body by special structural design of the end wall sections and by bulging Stirnv / and sheets to increase the loading capacity of the vehicle maximum and to reduce the net mass of the vehicle ·

According to the invention, this object is achieved in that the bulged in a known manner end wall plate is connected to the likewise bulged side wall plate via a contour of the two bulges following curved and thus elastic corner pillar and that the bulged end wall plate in the upper region in the middle corner of a Doppelwinkelpröfils, wherein the double angle profile in its vertical axis is approximately designed as a carrier of the same flexural strength and that the Stirnv / andblech in his

lower part is continued as a shear plate in the subframe stem.

According to a further feature of the invention, the curved corner column can be formed by the direct joining of the bulged end wall sheet with the bulged side wall sheet or «by the direct joining of the bulged, 'Stirniwandbleches with a newly executed side wall plate, wherein the flat side wall panel at the end of the carcass the contours End wall sheet and the connection of the double angle profile is adapted to the flat side wall panel ·

According to Pig. 1 and 2 is the end wall according to the invention aas the upper boundary profile, designed as Doppe1-winke! Profile $ 5 the head S and the spatially curved corner pillars 4 $ which are interconnected by a strongly curved side wall plate 1, whereby a diagonal elastic frame is formed ο The diagonal elasticity is reached by the curved corner pillars. By arranging the diagonal elastic end wall parts according to the invention at both ends of the wagon, the torsional rigidity of the wagon body is reduced and thus the derailment safety of the vehicle increased. In order to achieve great elasticity of the curved Eeksäulen 4, according to the invention, the end wall panel 1 maximally above the side buffers 9 to the required Pre-bulges arched, whereby at the same time a maximum increase in the loading volume is achieved. Furthermore, caused by the strong bulge of the end wall panel 1, the vertical output forces at horizontal end wall loads caused by buffer shocks.

By connecting the upper side of the bulging Stirnwandblecnes 1 at the central corner point 6 of a double angle section 5, the aforementioned profile is torsionally loaded and therefore can be formed as a torsionally soft profile, whereby a further reduction in the torsional rigidity of the car body is achieved. The same advantage is achieved by the continuation of the bulged end wall plate 1 as a thrust plate 7 of the base frame, whereby the head piece 8 is primarily loaded only vertically.

Due to the formation of the double angle profile 5 in its vertical axis as a carrier equal bending strength, the shape of the increase of the profile to the center of the upper end wall boundary approximately corresponds to the angle of repose of the load, a protection against falling of the bulk material is achieved at horizontal movements resulting from buffer standing at the same time.

In order to compensate tolerances between the bulged end wall sheet 1 and the bulged side wall sheet 2, according to Jig. 3, a curved corner column 4 "consisting of a hexagonal profile is arranged, and with appropriate technological prerequisites, the curved corner column 4 can be formed by the direct joining of the arched end wall panels 1 and the bulged side wall panel 2 to achieve an extreme lightweight construction.

Accordingly -7ig. 4 is in the Stirnwsndpartie invention, the curved corner column 4 by the direct joining of a susgewölbten end wall panel 1 with a. nem level side wall panel 3 is formed. In doing so, according to ig. 5 the flat side wall plate 3 at its end to the contours of the bulged end wall panel 1 and the connection of the double angle 5 to the flat side 'wall bleoh 3 adapted.
