Abstract

The invention relates to a light-weight suspension system of an automobile, in particular to a carbon fiber composite McPherson suspension control arm. The carbon fiber composite McPherson suspension control arm comprises a control arm body, a first bushing connected with an automobile body, a second bushing connected with a steering knuckle and a ball pin, wherein the control arm body is made of a carbon fiber composite and is hollow in the middle part; a first bushing end on which the first bushing is mounted, a second bushing end on which the second bushing is mounted, and a ball pin end to which the ball pin is connected are respectively arranged on the control arm body. The control arm disclosed by the invention has the advantages of being light in mass, high in intensity, high in impact resistance and the like, and the thickness can be designed, realization of the light weight of automobile parts is facilitated, and the development requirements of a conventional automotive technology for the respects of being energy-saving, environmentally-friendly, safe and the like are met; in addition, the invention further provides a preparation method of the control arm.

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...
