Vehicle front suspension bracket control arm

Abstract

The invention discloses a vehicle front suspension bracket control arm, and belongs to the field of vehicle structures. The vehicle front suspension bracket control arm comprises a control arm body with three arms, wherein the control arm body is integrally cast and formed, a ball stud assembly, a rear rubber bushing assembly and a front rubber bushing assembly are respectively arranged on the end parts of the three arms. According to the vehicle front suspension bracket control arm, an integral type cast steel structure is adopted, the yield strength of a material is extremely higher than that of the conventional pressing sheet material, and the material has certain extensibility; the advantages of a sheet metal component control arm are synthesized; and the vehicle front suspension bracket control arm is simple in technology, easy to process, high in rigidity, low in noise, convenient to arrange and wide in application range, and is suitable for large batch production.

Description

technical field [0001] The invention belongs to the field of vehicle structures, in particular to an automobile front suspension control arm. Background technique [0002] The control arm of the front suspension of the car belongs to the suspension guide part, which connects the frame and the steering knuckle, plays the role of transmitting the force and moment between the wheel and the body, and ensures that the wheel bounces relative to the whole vehicle with a certain trajectory. [0003] At present, the manufacturing process of the Ferson front suspension control arm of most SUV series vehicles adopts traditional stamping, welding and other methods to form a spliced ​​control arm structure, and the structure is mostly a single-plate control arm or a double-layer box control arm. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] The load-bearing capacity of the single-p...

AI Technical Summary

Problems solved by technology

[0005] The load-bearing capacity of the single-plate control arm is relatively weak, and it is mostly used on small or miniature vehicles with low force. The advantage is economical, but the load-bearing capacity is insufficient; The safety performance is better, but it does not meet the growing trend of modern lightweight
