Wear-resistant steering tie rod ball head structure and steering tie rod assembly

Abstract

The invention discloses a wear-resistant steering tie rod ball head structure and steering tie rod assembly. The structure comprises a shell, a tie rod main body and a ball head main body, a sleeve rod is fixedly mounted on the surface of one side of the shell, the pull rod main body is arranged in the sleeve rod, and a protruding block is clamped to the outer wall of the lower end of the shell; the end, extending into the shell, of the protruding block is connected with an end cover, the upper end of the end cover is connected with a movable block, one end of the movable block is connected with a rotating shaft, the rotating shaft is rotationally connected with the inner wall of the shell, the upper end of the movable block is connected with a supporting block, and a first fixing block isinstalled on the surface of the supporting block, and a second fixed block is fixedly mounted on the inner wall of the shell. According to the wear-resisting steering tie rod ball head structure andthe steering tie rod assembly, by arranging the supporting block made of the elastic rubber material, the buffering effect between the supporting base and the shell is improved, the friction strengthof the ball head main body during operation can be better reduced, the wear resistance is improved, and the service life of the ball head main body is prolonged.

Description

technical field [0001] The invention relates to the technical field of steering rods, in particular to a wear-resistant steering rod ball joint structure and a steering rod assembly. Background technique [0002] Steering rod is an important component part in the driving of a car. It directly affects the stability of car handling and driving safety. Steering rods can be divided into two types, namely straight rods and horizontal tie rods. However, the existing wear-resistant steering rod ball The head structure and steering rod assembly generally have the following problems during use; [0003] 1. During the long-term use of the ball head, under the influence of the friction of the base, the wear phenomenon is more serious. At the same time, it is inconvenient to disassemble the end cover, which causes inconvenience to the maintenance work of the ball head, thereby reducing the service life of the ball head , increasing the overall maintenance cost; [0004] 2. It is not c...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a wear-resistant steering tie rod ball head structure and steering tie rod assembly to solve the problem that the ball head proposed in the above background technology is not affected by the friction of the base during long-term use, which makes the wear phenomenon more serious. At the same time, it is inconvenient to disassemble the end cover, which causes inconvenience to the maintenance work of the ball head, thereby reducing the service life of the ball head, increasing the overall maintenance cost, and is not conducive to the disassembly of the dust cover, making the dust cover After long-term use, too much dust accumulates, which reduces the efficiency and accuracy of the ball head when steering, thereby reducing the stability and safety of the car during driving.
