[0002] The ball head refers to the hand tie rod ball head, and the inner ball head refers to the steering gear tie rod ball head. The automotive ball shell is a part of the automotive parts, mainly used to install the ball pin, which plays a steering role. The material hardness difference between the automotive ball shell and the ball pin is large. Long-term friction contact, especially when the road conditions are bad and the vehicle is turning, the ball pin twists and rubs the automotive ball shell, causing abnormal wear of the automotive ball shell for a long time.

[0003] Most of the existing automobile chassis ball shells are protected from the outside. During the subsequent driving of the car, dust, mud and water are easily attached to the rotating ball joint, which can easily cause the overall friction of the rotating ball joint to decrease, and affect the subsequent driving of the car. Therefore, an automobile chassis ball shell is needed to assist in solving this problem. Utility Model Content
