Abstract

The invention relates to the technical field of automobile parts, in particular to a stress testing device for a car suspension control arm bushing stiffening piece. The device comprises a fixing table, bushing and stiffing piece fixtures, a stability stress testing device and an instantaneous momentum testing device, the bushing and stiffing piece fixtures are fixedly mounted on both sides of thefixing table, a bushing and a stiffing piece are assembled in one piece, the two sides are respectively mounted on working ends of the two bushing and stiffing piece fixtures, the bushing and stiffing piece fixtures are located on both sides of the bushing in the axial direction, the stability stress testing device and the instantaneous momentum testing device are respectively located on both sides in the radial direction of the bushing and fixedly mounted on the fixing table, and the working ends of the stability stress testing device and the instantaneous momentum testing device are provided with the bushing fixtures. The device applies stress through a simulation control arm, a test result is close to a real situation, the bushing and the stiffing piece can perform stability stress testing and instantaneous momentum testing, and the result is closer to an actual driving situation.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a stress test device for a bush reinforcement of an auto suspension control arm. Background technique [0002] The design defect of "split control arm bushing" SAIC-GM developed a brand-new split-structure lower swing arm bushing in 2013 for use in Envision, Xinyinglang and other models. Shortly after listing, Envision Cases of off-axis (front lower swing arm and sub-frame detachment) have been reported in a number of models. Most of the vehicles are in the case of a certain collision or not serious stress. The subframe can easily detach, leading to more serious accident consequences. [0003] SAIC GM has recently recalled vehicles that use split bushings. The solution is to add a reinforcement, which is fixed at both ends of the split bush to reinforce the split bush to prevent it from Failure and fracture in lower load impacts, for this reinforcement, a stress test device ...
