Abstract

The embodiment of the invention provides a car body structure of a railroad car. The car body structure comprises a base frame, side walls, a car roof and end walls, wherein the base frame comprises abase frame skeleton and a lower cover board arranged at the base frame skeleton; the base frame skeleton comprises base frame longitudinal beams arranged from one end of the base frame skeleton to the other end thereof; side walls comprise side wall skeletons and side wall boards arranged at the side wall skeletons; the side wall skeletons comprise side wall columns in Z-beam structures and sidewall longitudinal beams which are in the Z-beam structures and arranged between the corresponding side wall columns; the car roof comprises a car roof skeleton and a car roof board arranged at the carroof skeleton; and the car roof skeleton comprises car roof curved beams in the Z-beam structures. Through the improvement of the structures of the large parts of a body structure in the prior art, the car body structure of the railroad car realizes the overall spraying of anti-corrosive coatings on a car body skeleton and solves the problem of easy corrosion of the car body skeleton.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a rail vehicle body structure. Background technique [0002] With the development of the national economy, the advancement of science and technology, and the improvement of people's living standards, the design level of rail vehicles has also continued to develop. In order to improve the market competitiveness of rail vehicles, it is necessary to comprehensively consider the structure of the car body structure, manufacturing process, economic indicators and comfort, and improve the design level of the whole vehicle. [0003] At present, the existing rail vehicles usually adopt a body structure without a center sill, which is mainly welded by four parts: the underframe, the side wall, the roof and the end wall. Side wall panels, end wall panels, and roof panels are respectively welded on the outside of the side wall frame, roof frame, and roof frame. A longitudinal corrugated f...
