The invention belongs to the technical field of thrust rod ball pins, and particularly relates to a commercial vehicle hollow ball pin which comprises a ball part and connecting parts symmetrically connected to the two sides of the ball part, and the ball part and the connecting parts are of an integrally-formed structure. The ball part is of a cavity structure, and the thickness of the ball part is gradually increased from the middle to the two ends. The invention further provides a preparation method of the commercial vehicle hollow ball pin. According to the commercial vehicle hollow ball pin, the surface of the ball part is free of turning defects, and the notch effect is avoided; compared with the commercial hollow ball pin, the mass is reduced by 40%, and the light weight is improved; the integrally-formed structure greatly enhances the strength.

    本申请属于推力杆球销技术领域,具体为一种商用车空心球销,包括球部和对称连接在球部两侧连接部,所述球部和连接部为一体成型结构;所述球部为空腔结构,所述球部的厚度由中间向两端逐渐增大。本申请还提供一种商用车空心球销的制备方法。本申请提供的商用车空心球销,球部表面无车削缺陷,避免切口效应;该商用空心球销相比质量降低40%,提高轻量化;一体成型结构大大增强了其强度。
