AI Technical Summary

Technical Problem

In existing rear suspension control arms, the space between the shock absorber, reinforcement, and spring is narrow, making it easy for collisions to produce abnormal noises, and the manufacturing process is difficult.

Method used

A spring tray is installed between the two side walls of the control arm body. The spring tray supports the spring and acts as a reinforcement, increasing the distance between the shock absorber and the spring tray. The connection stability and strength are improved through the flange and weld structure.

Benefits of technology

It improved the abnormal noise problem, reduced the processing difficulty, and improved the structural strength and connection stability of the suspension control arm.

Abstract

The application relates to the technical field of vehicle chassis, and provides a rear suspension control arm and a vehicle. The rear suspension control arm comprises a control arm body, a bottom plate and two side walls arranged on the two sides of the bottom plate and oppositely arranged, a spring tray connected to the two side walls, and a central boss for positioning a spring, the spring tray being used for supporting the spring. The rear suspension control arm is provided with the spring tray connected to the two side walls of the control arm body, so that the spring tray can support the spring, can also serve as a reinforcing piece to improve the structural strength of the rear suspension control arm, compared with the reinforcing piece in the form of surrounding the spring in the current technology, the distance between the spring tray and the shock absorber can be increased, and there is no gap between the spring tray and the spring in the circumferential direction of the spring, so that the abnormal sound problem can be improved.
