Abstract

The invention discloses an automobile lower suspension arm assembly and belongs to the field of automobile parts. The automobile lower suspension arm assembly is mainly composed of a lower suspension arm main body assembly and a shaft pin lining sleeve, a front shaft sleeve and a ball pin bracket which are arranged on the lower suspension arm main body assembly, and is characterized in that the lower suspension arm main body assembly is composed of an upper plate, a lower plate and a reinforcing plate; the upper plate and the lower plate both have U-shaped structures; the two sides of the upper plate and the lower plate are connected through welding; the reinforcing plate is arranged in the lower plate; positioning holes are correspondingly formed in the upper plate, the lower plate and the reinforcing plate. According to the invention, the two sides of the upper plate and the lower plate are welded and the reinforcing plate is arranged on the lower plate, so that the connecting strength of the automobile lower suspension arm assembly is increased, the welding precision of the upper plate and the lower plate is increased, the firmness and strength of the automobile lower suspension arm assembly are greatly increased, and the automobile lower suspension arm assembly is difficult to deform and crack after long-term use and has the characteristics of simple processing, convenience in implementation, low production cost, and the like.

Description

[0001] technical field [0002] The invention relates to the field of auto parts, in particular to an automobile lower swing arm assembly. Background technique [0003] The lower swing arm assembly of the car is located between the car body and the steering wheel. It is the main guide rod of the suspension and can also function as a thrust rod to withstand the longitudinal and lateral forces when starting, braking and turning. One of the main components of performance. Because the car runs on uneven roads, the wheels will vibrate, and the vibration will easily deform the welded part of the existing lower swing arm assembly. After a long time, cracks will appear in the lower swing arm, which will affect the normal driving of the vehicle and reduce the use of the vehicle. security. Contents of the invention [0004] The purpose of the present invention is to solve the problem that cracks will appear in the lower swing arm of the existing automobile when the car is running ...
