MacPherson air suspension and assembly method thereof

Abstract

A MacPherson air suspension comprises a cross stabilizer bar, two strut assemblies arranged on the left side and the right side of the cross stabilizer bar, a left steering knuckle, a right steering knuckle, a left lower suspension arm, a right lower suspension arm and a left-right stabilizer bar connection push rod connecting the cross stabilizer bar and the strut assemblies. Each strut assembly comprises a front shock absorber and an air spring assembly integrated on the front shock absorber, and the front shock absorber is fastened with the lower support of the front shock absorber through bolts. The upper ends of the left steering knuckle and right steering knuckle are respectively connected with the upper portion of the lower support of the front shock absorber through ball pin fittings, the lower portions of the left steering knuckle and right steering knuckle are connected with shaft sleeve connection plates of the steering knuckles through shaft pins and are connected with the lower portion of the lower support of the front shock absorber through the shaft sleeve connection plates, and the left steering knuckle and right steering knuckle respectively form an integrated frame structure with the lower support of the front shock absorber. The central connection line of the ball joints of the ball pin fittings and the shaft sleeves of the shaft sleeve connection plates of the steering knuckles is a main pin axis a. The MacPherson air suspension can meet the requirements of an automobile under various loading conditions, and ideal comfortable ride comfort can be obtained.

Description

technical field [0001] The invention relates to a front independent suspension mechanism of a vehicle, in particular to a McPherson air suspension and an assembly method thereof. Background technique [0002] Many of the car front suspensions in the current market use McPherson suspensions, such as the attached Figure 6 As shown, the existing MacPherson suspension is composed of strut assembly 1a, steering knuckle 2a, lower swing arm 3a, lateral stabilizer bar 4a and stabilizer bar connecting rod 5a, etc., wherein the strut assembly is composed of coil spring 6a, buffer The block 7a, the front suspension support 8a and the plane bearing 9a are collectively installed on the shock absorber. The pillar assembly is installed on the steering knuckle through the steering knuckle bracket 10a on the shock absorber; All of these impact forces are buffered and damped by coil springs and shock absorbers, and finally transmitted to the vehicle body; at the same time, the shock absorber...
