Abstract

The invention provides a vehicle body of a railroad vehicle and the railroad vehicle. The vehicle body of the railroad vehicle comprises a lateral wall, an end wall, a bottom frame and a roof, wherein the lateral wall comprises a Z-shaped end stand column; the end wall comprises a U-shaped end corner column; one part, far away from an end wall plate, on the bottom surface of the U-shaped end corner column is provided with a concave surface; an end face, welded with a lateral wall plate, of the Z-shaped end stand column is overlapped on the concave surface; the overlapping amount of overlapping the end face, welded with the lateral wall plate, of the Z-shaped end stand column on the concave surface is determined according to a deviation amount of the length of the bottom frame in the direction of the lateral wall and the length of the lateral wall; the Z-shaped end stand column is connected with the concave surface through a welding manner. According to the vehicle body of the railroad vehicle and the railroad vehicle, provided by the invention, the perpendicularity of the end wall installation can be guaranteed, the welding working amount of connecting the vehicle body can be reduced and the working efficiency of welding is improved.

Description

technical field [0001] The invention relates to railway vehicle technology, in particular to a railway vehicle body and a railway vehicle. Background technique [0002] The car body of a railway vehicle is mainly composed of several parts such as roof, side wall, end wall, and underframe, wherein the edges of each part are welded together to form a box-shaped car body structure. In the composition process of the car body, the side wall is usually welded to the bottom frame first, and then the end wall is welded to the bottom frame and the side wall, because the length of the bottom frame in the side wall direction and the length of the side wall are different There will be a certain deviation in the production process. When the side wall is welded to the bottom frame, the length of the bottom frame in the direction of the side wall is not exactly equal to the length of the side wall. In this way, after the end wall is welded to the bottom frame and When it is on the side wa...
