A ball head rod, ball hinge node and inner transverse pull rod for passenger car steering gear

By creating an oil reservoir on the ball joint and injecting lubricating grease, combined with a wear-resistant layer and elastic elements to adjust the rotational torque, the problem of poor lubrication at the ball joint of the inner tie rod was solved, achieving good rotational performance and reduced wear.

AI Technical Summary

Technical Problem

Poor lubrication of the existing inner tie rod ball joint leads to problems with smooth rotation, affecting the stability of the vehicle steering system.

Method used

An oil reservoir is made on the clubhead, and lubricating grease is injected when the clubhead is assembled with the club end. The lubricating grease in the reservoir seeps into the friction surface for lubrication during use, and the torque is adjusted in combination with the wear-resistant layer and elastic components.

Benefits of technology

It effectively improves the lubrication performance of the ball joint, ensures smooth rotation over a long period of time, reduces wear, and lowers replacement costs.

Abstract

本发明公开一种球头杆、球铰节点及乘用车方向机用的内横拉杆，包括杆体和设于杆体端部的球头，球头上开设有储油结构。本发明通过在球头杆的球头上开设储油结构，在储油结构内注入润滑油脂，如此，在该球头杆与杆端体装配在一起的时候，储油结构内的润滑油脂会在使用过程中逐渐渗入到摩擦面内产生润滑作用，进而有效地保证球铰节点长期保证良好的转动性能。
