Abstract

The invention discloses an auxiliary frame structure for a car chassis. The auxiliary frame structure comprises a front tubular beam and a rear tubular beam, the front tubular beam and the rear tubular beam are connected through a car body support, connecting supports are connected to the left ends and the right ends of the front tubular beam and the rear tubular beam, each connecting support is composed of an upper support body and a lower support body, and the outer ends of the connecting supports are connected with lining installation bases. And vehicle body bushings are mounted on the lining installation bases. The connecting supports are formed by tailor-welding the upper support bodies and the lower support bodies, so that the single-piece cost of a rear auxiliary frame is reduced, and the manufacturing defects caused by difficult forming are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile chassis frames, in particular to a sub-frame structure for a car chassis. Background technique [0002] The general connection method of the front and rear tube beams of the frame-type rear sub-frame and the mounting bracket of the vehicle body is composed of steel castings or single stamping parts, and then assembled into a rear sub-frame assembly by welding, using a single stamping part structure, single The shape of the parts is complex and the manufacturing process is difficult to realize, and manufacturing defects are prone to occur in the manufacturing process, and the production cost is high, so it becomes very important to solve this problem. Contents of the invention [0003] The object of the present invention is to provide a sub-frame structure for the chassis of a car, which uses a combination of upper and lower stamping parts of the upper body of the bracket and the lower body of...
