Abstract

The invention discloses a rear trailing arm, which belongs to the technical field of automobile rear suspension. The rear trailing arm includes: an upper body, a lower body, a bushing, an upper swing arm connecting seat, a lower swing arm connecting seat, a brake mounting platform and a shock absorber mounting platform. By matching the upper body and the lower body formed by stamping a single-layer steel plate into a cavity, the overall strength of the rear trailing arm can be greatly improved, and the use of reinforcement plates can be reduced or avoided; and the first end of the cavity is stamped It can avoid the use of the transition arm by forming a suitable shape to directly connect with the bushing; thus, the rear trailing arm structure provided by the embodiment of the present invention can simplify the structure and processing procedures while ensuring the practical strength; and due to the stamping process The use of the invention and the simplification of the structure of the present invention greatly reduce the overall number of welding parts, thereby reducing the welding deformation of the rear trailing arm during the welding process, thereby improving the positioning accuracy of each joint of the rear trailing arm.

Description

technical field [0001] The invention relates to the technical field of automobile rear suspension, in particular to a rear trailing arm. Background technique [0002] The rear trailing arm is a commonly used connector for the rear suspension of a car. It can be longitudinally connected between the body and the rear wheels through the connection with the upper swing arm and the lower swing arm, so as to support the body and act on the road surface on the wheels. The purpose of force transmission to the body is to ensure the normal driving of the car; through the connection of hydraulic shock absorbers and coil springs, the purpose of shock absorption of the body is achieved. [0003] At present, the rear trailing arm generally includes: an upper body, a lower body, an upper swing arm connecting seat, a lower swing arm connecting seat, a shock absorber mounting platform, a bushing, a transition arm and a plurality of reinforcing plates. The upper body and the lower body coope...
