Abstract

The invention discloses a rear wheel camber angle adjusting device of an automobile. The rear wheel camber angle adjusting device includes an eccentric bolt, an elastic sleeve, an eccentric spacer and a locknut. The eccentric bolt is sleeved with the elastic sleeve which is positioned among the eccentric bolt, a lower swing arm installing head and a lower swing arm mounting rack, an axial through groove is arranged on the elastic sleeve, the locknut is screwed up to compel the two ends of the elastic sleeve to shrink to the middle, and the axial through hole extends outwards along the radial direction due to the axial pressing force, namely the elastic sleeve expands in radial direction so as to compensate assembling clearances among the eccentric bolt, the lower swing arm installing head and the lower swing arm mounting rack, the eccentric bolt is prevented from shaking in a lower swing arm and a rear subframe, and the locknut is prevented from being deflected on the eccentric bolt by the shake, the screw loose of the eccentric bolt is reduced, and the service life of the eccentric bolt is improved, and meanwhile the rear wheel camber angle is accurately positioned b the eccentric bolt, and the safety performance of the automobile is improved.

Description

technical field [0001] The invention relates to the field of alignment of automobile rear wheels, in particular to an automobile rear wheel camber adjustment device. Background technique [0002] After the car is assembled, the front and rear wheels need to be positioned. They are of great significance to the handling of the vehicle and the reduction of component wear. Among them, the accurate positioning of the rear wheel camber in the rear wheel positioning can enhance the driving safety of the car. , Reduce tire wear, suspension component wear and other problems. [0003] In the prior art, the adjustment of the rear wheel camber of the automobile is generally realized by adjusting the relative position of the lower swing arm on the rear sub-frame through eccentric bolts. The position connected to the lower swing arm on the rear sub-frame is called the lower swing arm. Mounting bracket, there are two legs on the lower swing arm mounting bracket, one end of the lower swing...
