Product Description
It is generally recommended to replace the control arm after 3-5 years of use or when there is a deformation or abnormal voise, to ensure the safety and the comfortness of driving operation.
Control arm plays an essential parts in the car suspension system, and its functions are as follows:
1. The control arm is necessary in connecting the wheel and the frame. By connecting the wheel axle with the supporting point on the chassis, the wheel is closely linked with the frame, so that the wheel can move according to the designed trajectory.
2. The control arm bears the weight of the car body and transfers the gravity of the car body to the wheels. By connecting the wheel axles with the supporting points on the chas, it distributes the weight of the car body evenly to each wheel, thus maintaining the balance and stability of the car body.
3. The control arm affects driving stability of the vehicle by controlling the wheel movement. It can adjust the up-and-down movement of wheels to adapt to different road conditions and driving needs. By controlling the movement of the wheels, the control arm can provide comfortable riding experience and stable handling performance.
4. The control arm plays the role of buffering and shock absorption between the wheel and the chassis. It can absorb the impact and vibration from the road surface, reduce the impact on the car body and provide a more stable driving experience.
5.Ball joint: The balljoint steel is national standard 40CR, which has the best comprehensive mechanical properties; the hardenability of this steel is higher than 45 steel (a high-quality carbon structural steel) and is suitable for high-frequency quenching, flame quenching and other surface hardening treatments.
