Abstract

The invention relates to a cross beam assembly of a passenger car. The cross beam assembly comprises a front section beam assembly, a left connecting longitudinal beam assembly, a right connecting longitudinal beam assembly, a left back air bag support assembly and a right back air bag support assembly, wherein the left connecting longitudinal beam assembly and the right connecting longitudinal beam assembly are symmetrically arranged on back sides of left and right ends of a middle section of the front section beam assembly, and the left back air bag support assembly and the right back air bag support assembly are symmetrically arranged on back sides of left and right ends of the front section beam assembly. The cross beam assembly of the passenger car can overcome defects in the prior art, has the characteristics of high universality, high structural strength and the like and is suitable for batch and large-scale production and preparation, the production cycle can be effectively shortened, and the labor intensity can be reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of passenger cars, in particular to a cross beam assembly of a passenger car. Background technique [0003] Due to the characteristics of structural strength and good passive safety, fully loaded passenger cars have been widely used in existing high-end large passenger cars. Since the frame of a full-loaded bus is an integral truss-type closed-loop structure, its main body is welded by a large number of small rectangular tubes. Therefore, there are problems such as high welding labor intensity, heavy workload, and welding precision in the manufacturing process of full-loaded buses. Difficulties that require various tooling guarantees. [0004] Among the five skeletons of a fully loaded bus, the chassis is the most difficult to weld and has the most complex structure. The underframe is mainly composed of beam assemblies arranged in sequence from front to back through longitudinal connecting beam as...
