MacPhersan type suspension camber angle adjusting structure

Abstract

The invention discloses a MacPhersan type suspension camber angle adjusting structure which comprises a shock absorber body. Long round holes are formed in the side faces at the lower end of the shockabsorber body. Limiting structures are arranged on the outer sides of the long round holes. An eccentric bolt assembly is arranged in the long round holes in a matched mode and comprises an eccentricbolt, an eccentric spacer and a nut. By the adoption of the structure, a suspension camber angle can be adjusted, the adjusting amount of the eccentric structure ranges from -2.5 degrees to 2.5 degrees through strict analysis and calculation, and according to actual production statistics and after-sale statistics, it can be guaranteed that all the camber angles are qualified. Due to the fact thatthe camber angle can be adjusted, the requirement for the accuracy of suspension parts is lowered, the manufacturing cost is saved, meanwhile, the percent of pass of the parts is increased, and the production efficiency is improved. The camber angle is adjustable, so that the requirements for a suspension assembly process and tools are lowered, the tool cost is saved, the whole vehicle offline percent of pass is increased, and the production efficiency of a main machine factory is improved. The camber angle is adjustable, so that the maintenance cost of an after-sale vehicle is reduced, the maintenance efficiency is improved, and the cost of a vehicle owner is greatly reduced.

Description

technical field [0001] The invention relates to an adjustment structure, in particular to a McPherson type suspension camber angle adjustment structure. Background technique [0002] McPherson suspension is a kind of independent suspension, which is one of the most popular independent suspensions today, and is generally used for the front wheels of cars. Simply put, the main structure of the McPherson suspension is composed of a coil spring and a shock absorber. The shock absorber can prevent the coil spring from shifting forward, backward, left, and right when it is stressed, and the spring is limited to only It can vibrate in the up and down direction, and the stroke length and tightness of the shock absorber can be used to set the hardness and performance of the suspension. Although the performance of the MacPherson suspension is satisfactory in terms of driving comfort, its structure is small and can effectively expand the seating space in the car, but because of its st...

Problems solved by technology

[0004] At present, the camber angle of the McPherson suspension is not adjustable, and its structure has the following disadvantages: the camber angle cannot be adjusted, which requires higher manufacturing precision of the suspension parts, which increases the manufacturing cost; the camber angle cannot be adjusted, and requires high The assembly process and tooling requirements increase the manufacturing cost; the aftermarket cannot be repaired, and the suspension parts need to be replaced, which increases the maintenance cost
