Abstract

The invention belongs to the field of automobile suspension testing, and particularly relates to an automobile suspension fatigue test load loading device. The automobile suspension fatigue test load loading device comprises a tested suspension assembly, a power output structure, a crank connecting rod structure, a device support, a simulation automobile body and the like. The tested suspension assembly is installed on the device support, the other end of the suspension assembly is provided with the simulation automobile body, the power output structure is connected with the crank connecting rod structure, and the crank connecting rod structure is connected with the simulation automobile body, so that force is transmitted to the automobile body, and the simulation automobile body is driven to move through periodic movement of a crank connecting rod. Therefore, the effect of simulating automobile body motion load is achieved.

Description

technical field [0001] The invention belongs to the field of automobile performance testing, in particular to an automobile suspension fatigue test load loading device. Background technique [0002] In recent years, with the advancement of science and technology, the development of social economy and the gradual improvement of people's living standards, people's demand for cars is increasing, and the use of cars is becoming more and more popular, and car suspension is an important component of cars , Technically speaking, automobile suspension refers to the general term for all transmission devices between the frame, body and axle. The vertical reaction force (supporting force), longitudinal reaction force (traction force and braking force) and lateral reaction force acting on the wheel by the road surface and the moments generated by these forces are all transmitted to the frame (or load-bearing body) through the suspension . The main function of the automobile suspension...
