A car tie rod assembly

Abstract

The invention discloses an automobile pull rod assembly. The automobile pull rod assembly comprises a pull rod, a ball pin and a ball seat structure for supporting the ball pin, wherein the ball pin comprises a ball head and a ball pin rod, and an accommodating cavity for accommodating the ball seat structure and the ball head is arranged in the pull rod. According to the automobile pull rod assembly disclosed by the invention, the accommodating cavity for accommodating the ball head and the ball seat structure of the ball pin is arranged in the pull rod, the pull rod is of an integral structure, the ball pin is directly mounted on the pull rod, and thus the bearing strength of the pull rod assembly can be improved; the structure of the pull rod assembly is simpler, the production technology can be simplified, and the production cost is reduced; moreover, components of the pull rod assembly can be changed individually, only damaged components are changed in case of failure, the assembly does not need to be changed, the using cost is reduced, the steering stability of large-torsion heavy machinery (such as large tractors, pavers, heavy trucks and the like) is guaranteed, and safety and reliability of steering operation are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular, the invention relates to an automobile tie rod assembly. Background technique [0002] The existing automobile steering rod is connected with the ball pin, and one end of the pull rod is provided with a spherical shell, and the ball head of the ball pin is inserted into the ball socket of the spherical shell to form a ball joint structure. Since the spherical shell, the tie rod and the ball head are assembled in separate parts, the formed tie rod assembly has the problem of low bearing strength, complicated process and structure, and high production cost. In addition, in the ball socket of the ball shell, the ball seat is provided with a support enclosing ball seat to support the ball head, and the ball pin will have an impact on the ball seat due to external force, which may easily cause damage to the ball seat. Contents of the invention [0003] The present invention aims ...

AI Technical Summary

Problems solved by technology

Since the spherical shell, tie rod and ball head are assembled in separate parts, the formed tie rod assembly has the problem of low load-bearing strength, and the process and structure are complicated, and the production cost is high

In addition, the ball socket of the spherical shell is provided with a lower support enveloping ball seat to support the ball head, and the ball pin will have an impact on the ball seat due to the external force, which may easily cause the ball seat to be damaged.
