Description

Technical Field

[0001] The utility model relates to the technical field of steering ball heads, in particular to a steering ball head for an automobile. Background Art

[0002] Automobile steering ball head generally refers to steering tie rod ball head, which is a spare part in automobile. Automobile steering ball head is widely used in independent suspension system. Automobile steering ball head provides multi-angle rotation when steering, so that the steering mechanism can steer smoothly. Its function is to reduce vibration and achieve smooth steering.

[0003] The existing automobile steering ball head, such as the one disclosed in publication number CN213117123U, has the advantage that the oil storage cavity is filled with lubricating oil so that the ball head can drive the lubricating oil to the contact surface between the ball seat and the ball head during operation, thereby improving the service life of the steering ball head. However, the outer end of the ball head of the steering ball head is not easy to be well sealed, and then after external dust enters the lubricating oil at the ball head, it will cause wear problems during the use of the ball head. Therefore, we propose an automobile steering ball head. Utility Model Content
