Connecting structure of axle bracket and thrust rod

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mechanical connection structures, in particular to a connection structure between an axle bracket and a thrust rod. Background technique [0002] The axle, also known as the axle, is connected to the frame through the suspension, and the wheels are installed at both ends. The function of the axle is to transmit the forces and moments in all directions between the frame and the wheels, which has an important impact on the vehicle's dynamic performance, stability, and load-carrying capacity. The thrust rod is an auxiliary component in the suspension system. It is a component used to maintain the stability of the axle. One end of the thrust rod is connected to the axle and the other end is connected to the frame. There are many types of thrust rods. The V-shaped thrust rod is a relatively common thrust rod at this stage. When the axle moves left and right, the triangular stable structure of the V-shaped thr...

Problems solved by technology

[0004] However, increasing the number of bolts or the diameter of the bolts to increase the overall axial preload of the bolts requires increasing the installation space to meet the assembly requirements. If the installation space is limited, increase the number of bolts or the diameter of the bolts to increase the axial preload of the bolts Therefore, it is necessary to redesign a connection structure to improve the reliability of the connection between the thrust rod and the axle bracket
