AI Technical Summary

Problems solved by technology

The shock absorption effect and controllability of this structure are the best, but the disadvantage is that the fatigue life cannot meet the requirements of use. The fatigue test of the control arm bushing bench proves that the rubber bushing 2 is easily damaged in the actual use process in its hollow direction. rupture
And for consumers, the rubber bushing 2 is damaged, that is, the control arm bushing is scrapped, causing even greater losses

Description

technical field [0001] The invention relates to a rubber composition used for a bushing of a control arm of an automobile chassis, which is used for making the bushing of a control arm of an automobile chassis, and belongs to the technical field of rubber. Background technique [0002] The automobile chassis is to support and install the automobile engine and its various components and assemblies, forming the overall shape of the automobile. Receive the power of the transmission system, and generate traction through the action of the driving wheel and the road surface, so that the car can run normally. At the same time, it bears the total weight of the car and the reaction force of the ground, eases the impact of uneven roads on the body, attenuates the vibration of the car during driving, and maintains the smoothness of driving; cooperates with the steering system to ensure the stability of the car. In an independent wheel suspension system, the control arm connects the ca...
