Abstract

The invention relates to the technical field of railway vehicle structures, and discloses a multi-bending stand column and a multi-bending stand column arrangement bearing light-weight side wall. A plurality of sets of bending channels are formed in the multi-bending stand column in parallel, a plurality of open holes and a plurality of stand column inner reinforcing channels are formed in the bending channels close to the outer edge of the multi-bending stand column, and the open holes are communicated with the stand column inner reinforcing channels. spot welding holes are formed in the same ends of each group of bending channels. By means of the multi-bend stand column structure, the bearing rigidity level of the stand column is improved, the cross section modulus of parts is increased, the structural requirement is met, and the purpose of weight reduction is achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle structures, in particular to a multi-bend column and a multi-bend column arrangement to carry a lightweight side wall. Background technique [0002] In the existing technology, in order to ensure the strength requirements of the car body, relatively thick side wall panels are used for the side walls, and a large number of components such as columns, horizontal bearings, and auxiliary support plates are arranged in the structure. The number of parts required for assembly is large, and the assembly time is long, making manufacturing difficult. With a corresponding increase, under the requirements of the axle load of the whole vehicle, there is almost no room for evolution in terms of lightweight. [0003] In order to achieve the purpose of reducing the weight of the whole vehicle, the built-in horizontal bearings and some reinforcing parts are evenly arranged between the wall panels and the ext...
