Description

Assembly for assembling control arm

Technical Field

The utility model relates to an auto-parts technical field, concretely relates to control arm assembly.

Background

The steering transmission mechanism transmits steering force and bears the impact and vibration generated by the steering wheel during running on uneven roads. The control arm assembly structure generally mounts a ball head assembly and a rubber bush assembly, respectively, through a plurality of link arms, for connecting the wheel with the vehicle body, to absorb and dampen vibrations from the wheel while transmitting driving and braking forces. Therefore, the reasonability of the structural design of the control arm of the steering system directly influences the comfort and the controllability of the vehicle in running under different road conditions.

In the prior art, the main structure of a ball joint assembly for a control arm of an automobile suspension system is formed by vulcanizing rubber on a metal ball pin. In the moving process of the automobile, the swinging angle of the vulcanized rubber ball joint assembly is realized only by the torsional deformation of the rubber, so that the swinging angle is smaller and the rubber ball joint assembly cannot be used for vehicles with larger requirements on the swinging angle. And the existing sealing ring is easy to wear and deform, and the sealing effect is difficult to avoid, so that the ball joint assembly is damaged quickly, the service life is short and other adverse factors are caused.
