Abstract

The invention provides a fatigue testing system for an outer connection sleeve of a suspension frame strut assembly. According to the fatigue testing system, the upper end of a piston rod of the suspension frame strut assembly (1) is connected with the outer connection sleeve (2); the outer connection sleeve (2) is arranged in an automobile body equivalent structural body (3); the lower end of the suspension frame strut assembly (1) is arranged in a sleeve assembly (7) which is connected with a structural body 1 (9); the structural body 1 (9) is connected with a first branch rod of a swing arm rod (10); a second branch rod of the swing arm rod (10) is connected with a structural body 2 (13) which is arranged on a ball (14); the ball (14) is positioned on an excitation test stand; the excitation test stand applies excitation to the ball (14); the ball (14) transfers excitation to the swing arm rod (10) from the structural body 2 (13); and a vertical rod of the swing arm rod (10) drives the piston rod to swing by sequentially using the structural body 1 (9), the sleeve assembly (7), and the suspension frame strut assembly (1).

Description

technical field [0001] The present application relates to the technical field of auto parts testing, in particular to a fatigue testing system for the outer coupling sleeve of the suspension strut assembly. Background technique [0002] Car suspension is a key part of car chassis system. Suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel), and is mainly composed of a suspension strut assembly and a guide mechanism. Wherein the outer coupling sleeve of the automobile suspension strut assembly is an elastic connection device between the shock absorber and the vehicle frame (or load-bearing vehicle body). During use, the outer coupling sleeve of the suspension strut assembly will be severely worn, which will affect its service life. Therefore, in the process of R & D and production, in order to improve the quality of the parts, it is necessary to carry out fatigue life tests on them. ...
