Description

A high-safety automobile steering rod

Technical Field

The invention relates to an automobile steering tie rod, in particular to a high-safety automobile steering tie rod applied in the field of automobile steering parts.

Background Art

The steering tie rod is an important part of the automobile steering mechanism, which directly affects the stability of automobile handling, the safety of operation and the service life of tires. The steering tie rod is divided into two categories, namely the steering tie rod and the steering tie rod. The steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism and is a key component to ensure the correct movement relationship between the left and right steering wheels.

Since the steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm, when the driving cycle of the car is too long or the driving road is mostly bumpy, it is easy for the steering tie rod to bear a greater impact force, especially the area where the ball head seats at both ends of the steering tie rod are connected is subjected to greater force, which can easily cause cracks or even breakage in the steering tie rod. If the steering tie rod breaks when the vehicle is driving, it will pose a high safety hazard. Therefore, a high-safety automobile steering tie rod is proposed to improve the above problem.
