Description

technical field

[0001] The invention relates to a lightweight suspension system for automobiles, in particular to a MacPherson suspension control arm made of carbon fiber composite material. The invention also provides a preparation method for the control arm. Background technique

[0002] The car control arm is used for the connection between the car body and the steering wheel, and bears the steering force and steering torque between the frame and the wheel. It is an important guiding part in the car suspension system and has an important impact on the stability of the car running. Traditional automobile control arms include forged type, double-piece steel plate welding type, single-piece steel plate stamping type, etc. Limited by the deformation ability of the steel plate, cracks are often caused by local uneven force during forging, flanging and other processes, and the product qualification rate is low; on the other hand, the light weight and weight reduction space of t...
