What is the purpose of the car control arm?

Suspension system is an important part of modern automobiles, which has a great influence on the ride comfort and handling stability of automobiles.

As the guide and force transmission element of the automobile suspension system, the control arm transmits various forces acting on the wheel to the body, and at the same time ensures that the wheel moves according to a certain trajectory. The control arm elastically connects the wheel and the body together through ball joints or bushings, respectively. The control arm (including the bushing and ball joint connected to it) should have sufficient rigidity, strength and service life.

The suspension system refers to the entire support system composed of springs and shock absorbers between the body and the tires. The function of the suspension system is to support the body and improve the riding feeling. Different suspension settings will make the driver have different driving feelings.
