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.
