Problems solved by technology

[0002] The steering gear bushing is a key part of the steering gear positioning structure. The wear of the steering gear bushing will lead to poor positioning of the steering gear in the steering system, which will lead to insufficient steering return and reduced steering accuracy when the vehicle is driving.
In order to solve the problem of bushing wear, the general rubber sleeve provided on the outside of the steering gear bushing in the prior art has the disadvantages of being not wear-resistant, easily deformed, and not resistant to aging
