Embodiment Construction

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0040] The side wall structure of the chassis is indispensable in locomotives. Due to the requirements of the process and the overall structure, the chassis 1 has an upward deflection, so the distance between the bottom of the column 21 on the side wall 2 and the chassis 1 will be different. Part of the uprights 21 on the side wall 2 can be in contact with the underframe 1 , while another part of uprights 21 on the side wall 2...

Abstract

The invention relates to the technical field of locomotive bodies, and provides an underframe side wall structure and a locomotive body. The underframe side wall structure comprises an underframe, side walls and a plurality of extension pieces. The underframe comprises a boundary beam and a bearing surface, and the boundary beam has upper deflection in the direction perpendicular to the bearing surface; the side walls comprise skins and a plurality of stand columns, wherein the plurality of stand columns are connected in parallel through the skins, and the side walls are fixed to the side beams and are perpendicular to the underframe; extending parts are fixed to the sides, close to the underframe, of the stand columns in a one-to-one correspondence mode, and the ends, close to the underframe, of the extending parts are fixed to the edge beams. Compared with the prior art, in the manufacturing process, only the extending parts on all the stand columns need to be adjusted, the distancesof the extending parts extending out of the stand columns need to be adjusted, the extending parts and the stand columns are fixed, it is guaranteed that the extending parts can be fixed to the underframe boundary beams, the grinding amount does not need to be reserved on the stand columns, assembling is easy, the size precision is easy to control, the grinding work is reduced, and the processingcost is reduced.

Description

technical field [0001] The invention relates to the technical field of locomotive body, in particular to an underframe side wall structure and a locomotive body. Background technique [0002] With the development of the transportation industry, the application of locomotives is becoming more and more extensive, and the locomotive body includes the underframe side wall structure. [0003] In the underframe side wall structure in the prior art, the connection between the underframe and the sidewall is not firm enough, the manufacture is difficult, the cost is high, and it is easy to fall off, and the stability is not good. [0004] Therefore it is necessary to design a new underframe side wall structure and locomotive body. [0005] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in the art to a ...
