Abstract

The invention discloses an automotive tie-rod end sealing structure. A dust cover (2) is made of flexible material, one end of which is sleeved on a ball shell (3), the other end is sleeved on the rod body of a ball pin (1); an annular groove is arranged on an outer circle on the end of the dust cover (2) sleeved on the ball shell (3), wherein a large collar (8) is arranged in the groove for clamping and securing the dust cover (2) on the ball shell (3); an annular groove is arranged on the other end of the dust cover (2) sleeved on the rod body of the ball pin (1), wherein a small collar (9) is arranged in the groove for clamping and securing the dust cover (2) on the rod body of the ball pin (1). Employing the technical scheme, the invention has reasonable structure, good manufacturability, prevention of abrasion on the pivot angle of the products, reduction of friction coefficient between the friction surfaces, good sealing performance, and improvement of the comprehensive performance of the products.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis structure, and relates to an automobile steering system. More specifically, the invention relates to a sealing structure of an automobile steering rod ball joint. Background technique [0002] Referring to the accompanying drawings of this description, the prior art is introduced: [0003] The traditional automotive steering tie rod ball seal structure such as figure 1 , figure 2 and image 3 As shown, its structure includes a ball pin 1, a spherical shell 3, a dust cover 2, a ball seat 5 and a cover 7, and the opening structure of the spherical shell 3 is oblong, which realizes a large swing in one direction and the small swing in the cross direction; the inside of the connection structure completely adopts metal-to-metal motion friction, and its base is an iron-based base and a compensation force spring 6; the outside of the connection structure adopts a tight-fitting dust cover 2...
