The invention discloses a connecting structure of an axle bracket and a thrust rod. The connecting structure comprises the axle bracket, the thrust rod and two bolts, wherein the axle bracket is provided with two mounting seats at an interval, each mounting seat is provided with a wedge-shaped groove, at least one side of each wedge-shaped groove is provided with a wedge-shaped surface, and each mounting seat is provided with a threaded hole at the lower part of the wedge-shaped groove; the thrust rod is provided with a pin shaft, wedge-shaped connecting blocks are arranged at the two ends ofthe pin shaft respectively, each wedge-shaped connecting block is attached to the wedge-shaped face of the corresponding wedge-shaped groove, a gap is reserved between each wedge-shaped connecting block and the bottom face of the corresponding wedge-shaped groove, and a through hole is formed in each wedge-shaped connecting block. And each bolt penetrates through the through hole of one wedge-shaped connecting block and is connected with the corresponding threaded hole, so that the thrust rod is connected with the axle bracket. By increasing the maximum static friction force of the wedge-shaped connecting block at the end part of the pin shaft of the thrust rod, the reliability of the connecting structure of the axle bracket and the thrust rod is improved.
本发明公开了一种车桥支架与推力杆的连接结构,该连接结构包括:车桥支架、推力杆以及两个螺栓;所述车桥支架间隔设有两个安装座,每个所述安装座均设有楔形凹槽,所述楔形凹槽至少一侧设有楔形面,每个所述安装座在所述楔形凹槽的下部均设有螺纹孔;所述推力杆设有销轴,所述销轴两端均设有楔形连接块,每个楔形连接块与一个所述楔形凹槽的楔形面贴合,且与该楔形凹槽的底面留有间隙,每个所述楔形连接块上均设有通孔;每个所述螺栓穿过一个所述楔形连接块的通孔与对应的螺纹孔连接,以使所述推力杆与所述车桥支架连接。本发明通过增大推力杆的销轴端部的楔形连接块的最大静摩擦力,提高车桥支架与推力杆的连接结构的可靠性。
