Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to an automobile suspension fatigue test tool. Background Art
[0002] Automobile suspension is a general term for all force-transmitting connection devices between the automobile frame (or load-bearing body) and the axle (or wheel). Its function is to transmit the force and torque acting between the wheel and the frame, and to cushion the impact force transmitted to the frame or body by uneven roads, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. Generally, when the test fixture is used to test the fatigue durability of automobile suspension springs, the suspension springs are directly mounted on the rod body used for limiting the position inside the test box. Due to the lack of functional settings for strengthening and fixing the suspension springs, the suspension springs are prone to position deviation during the test process, and there is a safety hazard that the suspension springs will bounce off the limiting rod body due to excessive test pressure, thereby reducing the use effect.
