Problems solved by technology

Over time, the nylon ball bowl 103 becomes thinner and thinner, which leads to gaps between the ball head 106, the nylon ball bowl 103, and the ball head seat 105, resulting in looseness, abnormal noise, and drop in swing torque.
As the gap between the ball bowl and the ball head becomes larger and larger, the pre-tightening force between the ball head and the ball head no longer exists, so that a constant swing torque cannot be maintained, which is likely to cause accidents. On the other hand, the ball stud pin The service life of the assembly is also greatly shortened

Abstract

The invention relates to a ball pin assembly, which comprises a ball cup, a ball bowl, a ball pin and a dustproof cover, wherein the ball bowl is positioned inside the ball cup; the ball pin is provided with a ball part and a pin rod part, wherein the ball pin is positioned in the ball bowl inside the ball cup; and the dustproof cover covers an opening of the ball cup, and the pin rod part extends out of the dustproof cover, wherein the inner surface of the ball cup is provided with holes, and elastic devices are respectively arranged in the holes and used for extruding the ball bowl to the ball part. According to the ball pin assembly disclosed by the invention, the service life of the ball pin can be prolonged, and phenomena, such as looseness, abnormal sound, non-constant sway moment between the ball and the ball bowl are eliminated.

Description

technical field [0001] The invention relates to vehicle technology, in particular to a ball stud assembly. Background technique [0002] The ball stud assembly, such as the steering tie rod ball stud in the steering gear of the automobile, the swing arm ball stud of the automobile front suspension, etc., is a key component of various types of auto parts and is widely used in automobiles. Specifically, the ball stud assembly can be used in automobile suspension systems and automobile steering systems. figure 1 A prior art ball stud assembly is shown. Specifically, such as figure 1 As shown, the ball stud assembly may generally include a ball stud 101 , a dust cover 102 , a nylon ball bowl 103 , a ball stud cover 104 , a ball stud seat 105 , and a ball head 106 . Wherein the ball head 106 is a part of the ball stud 101, the ball stud 101 passes through the ball head seat 205, the outside of the ball head 106 is wrapped by the nylon ball bowl 103, and the ball head 106 and t...
