Abstract

The invention relates to a fatigue test bed for an automobile suspension system. The test bed comprises a test bed flat plate with a fixed counter-force support arranged in the center, and an automobile suspension system needing to be subjected to a fatigue test is connected to the fixed counter-force support; two tire simulation clamp assemblies with a same structure are respectively connected tothe left end and the right end of the automobile suspension system; two longitudinal loading assemblies with a same structure are symmetrically and fixedly connected to the rear part of the test bedflat plate; two vertical loading assemblies with a same structure are symmetrically and fixedly connected to the front part of the test bed flat plate; two transverse loading assemblies with a same structure are symmetrically and fixedly connected to the middle of the test bed flat plate; and the left and right longitudinal loading assemblies, the vertical loading assemblies and the transverse loading assemblies are respectively connected with the tire simulation clamp assemblies connected to the left end and the right end of the automobile suspension system. According to the invention, the stress working condition of the automobile suspension system can be simulated, the test accuracy is improved, and the test period is shortened.

Description

technical field [0001] The invention relates to a performance test of an automobile component, in particular to a fatigue test bench for an automobile suspension system. Background technique [0002] The main function of the automobile suspension system is to transfer the vertical reaction force, longitudinal reaction force (driving force and braking force) and lateral reaction force applied to the wheels by the road surface to the body to ensure the normal driving of the car. Suspension system is an important part of a car, and its reliability is directly related to the safety of the vehicle. [0003] At present, the verification of the reliability of the automobile suspension system is mainly completed through the real vehicle road durability test and the indoor bench durability test. The road durability test of the real vehicle is to simulate the worst working conditions used by the user in the proving ground after all parts and components of the vehicle are installed ac...
