Control arm mainly composed of parts: brachial, bushing, ball joint and so on.
Control arm is also known as the swing arm; as the guide and transmission element of the automobile suspension system, the various forces on the wheel are transferred to the body, and the wheels are guaranteed to move in a certain trajectory. The control arm connects the wheels and body flexibly through ball hinges or bushing.
The control arm (including the bushing and ball joint that is attached to it) should have sufficient stiffness, strength and service life.
Control arm structure: 1. Horizontal stabilizer bar connecting rod; 2. Horizontal pull rod; 3, Vertical pull rod; 4. Single control arm; 5. Fork (V) arm; 6. Triangle-bracket
The fork (V) arm is used for the lower arm of the independent suspension of the double transverse arm or the lower arm of the McPherson suspension, and the triangle-bracket is used for the lower arm of the front McPherson suspension, which is used to transfer the transverse and vertical loads. These two kinds are our main control arm products.
