[0019] The present invention will be further described below in conjunction with the embodiments and drawings: Embodiment 1

[0020] like Figure 1 As shown, the rod body of the thrust rod includes a connecting rod 1 and a diffuser end. The diffuser end is seamlessly connected to the two ends of the connecting rod 1. The connecting rod 1 is a round steel tube. The diffuser end is formed by expanding, flattening and opening holes at both ends of the connecting rod 1 through tooling. Therefore, both diffuser ends are hollow structures with openings at both ends, and both hollow diffuser ends are connected to the connecting rod 1. The end of the diffuser end away from the connecting rod 1 is larger than the end of the diffuser end close to the connecting rod 1, and a through high-precision mounting hole 6 is also opened on the diffuser end.

[0021] The expansion end includes a flat side plate 2, a pipe expansion section 3 and a transition section 4; the length direction of the connecting rod 1, the pipe expansion section 3 and the transition section 4 is the longitudinal direction of the rod body, and the pipe expansion section 3 and the transition section 4 are arranged at the upper and lower ends of the rod body in the vertical direction; the flat side plate 2 is arranged on the left and right sides of the rod body in the transverse direction. One end of the transition section 4 is seamlessly connected to the connecting rod 1, and the other end of the transition section 4 is seamlessly connected to the pipe expansion section 3. The pipe expansion section 3 is a horizontally arranged arc plate, and the transition section 4 is an inclinedly arranged arc plate. The pipe expansion section 3 and the transition section 4 are seamlessly connected to form a broken line structure with an arc cross section; and the transition section 4 and the pipe expansion section 3 are respectively connected to a flat side plate 2 on both sides of the transverse direction.

[0022] The flat side plate 2 is a flat plate, and the flat side plates 2 are seamlessly connected on both sides of the expansion section 3 and the transition section 4 in the transverse direction, and the expansion section 3 and the transition section 4 are seamlessly connected at both ends of the flat side plate 2 in the vertical direction. The flat side plate 2, the expansion section 3 and the transition section 4 surround a hollow expansion end with openings at both ends in the longitudinal direction, and the opening outside the expansion end is a port 5; the port 5 of the expansion end is surrounded by the expansion sections 3 arranged at the upper and lower parts and the flat side plates 2 arranged at the left and right parts. The high-precision mounting hole 6 opened in the expansion end refers to a circular through hole opened in the two flat side plates 2 in the transverse direction.

[0023] like Figure 2 and Figure 3As shown, the ball joint includes an outer sleeve 7 and a core shaft 8. The core shaft 8 is vulcanized into a whole with the outer sleeve 7 through rubber, and both ends of the core shaft 8 extend out of the outer sleeve 7. The outer sleeve 7 of the ball joint passes through the high-precision mounting holes 6 on the two flat side panels 2 and is installed on the diffuser end in an interference fit manner. The ball joint is installed on the rod body of the thrust rod in an interference fit manner, compared with the existing ball head installed on the rod body of the thrust rod by riveting, friction welding or threaded fitting. The two high-precision mounting holes 6 of this embodiment improve the accuracy of the relative distance between the axle and the workshop, and reduce the energy consumption in the production process. The structure is simpler and the production efficiency is higher.
