Ball pin structure, front knuckle assembly and automobile chassis assembly

Abstract

The invention discloses a ball stud structure, a front knuckle assembly and an automobile chassis assembly, and relates to the technical field of automobile structure design. The ball pin structure is used for connecting the front steering knuckle and the control arm. The ball pin structure comprises a ball pin seat and a ball pin, wherein the ball pin seat comprises a pin seat main body and two connecting arms which are symmetrically arranged on the outer wall of the pin seat main body, and a spherical groove is formed in the pin base body, and the connecting arm is used for being connected with a front steering knuckle. a master pin, of which one end is a ball body that is rotatably matched with the spherical groove of the pin seat main body, and the other end is matched and fixed with the control arm. The front steering knuckle assembly comprises a front steering knuckle body and a ball pin structure. The automobile chassis assembly comprises a control arm and a front knuckle assembly. According to the ball stud structure, the front control arm assembly and the automobile chassis assembly, the ball stud structure can be independently disassembled and maintained, the lightweight design is met, and the structural stability is good.

Description

technical field [0001] The present application relates to the technical field of automobile structure design, in particular to a ball stud structure, a front steering knuckle assembly and an automobile chassis assembly. Background technique [0002] In the automobile structure, the suspension ball stud, as the key load-bearing structure of the automobile chassis, plays the role of connecting the front steering knuckle and the control arm. At present, the suspension ball stud has two structures, the first is an integrated structure, and the second is a separate structure. [0003] Specifically, as figure 1 As shown, the first ball stud 1a of the integrated structure is integrated at one end of the control arm, and is integrated with the structure of the control arm. like figure 2 As shown in the figure, the second ball stud 2a of the independent structure can be fixedly connected to the control arm by adding a connecting plate. When the second ball stud 2a is damaged, it ...

AI Technical Summary

Problems solved by technology

[0004] However, for the first ball stud 1a of the integrated structure, after the internal parts of the ball head are damaged, the entire control arm needs to be replaced, and the maintenance cost is high; the second ball stud 2a of the independent structure is fixed by a connecting plate, which increases the number of connections. The plate structure increases the weight, which is not conducive to the lightweight design requirements. At the same time, a small connecting plate is used to fix the first ball stud 1a to the control arm, and the structural stability is poor.
