Problems solved by technology

In the prior art, the ball seat is directly vulcanized and fixed in the ball stud installation cavity. At the same time, the inner bush, the outer bush and the main welded pipe are also vulcanized and fixed integrally, resulting in the ball seat, inner bush, The outer bushing and the main body of the automobile suspension control arm are integrally arranged and cannot be separated. Since the ball seat, inner bushing and outer bushing are all vulnerable parts, they will wear out after a period of use, and the After wear and tear, people need to replace the car suspension control arm as a whole, which not only greatly increases the maintenance cost, but also causes a waste of resources
