Main Functions

It controls wheel alignment and driving trajectory, ensuring wheels maintain correct angles such as caster and camber during suspension movement and steering, thus preventing uneven tire wear. It bears and transmits driving forces, including lateral and longitudinal forces generated during acceleration, braking, and cornering, to stabilize the vehicle’s body posture. Additionally, it works with shock absorbers to improve ride comfort and handling stability; any looseness or deformation in the control arm may lead to vehicle drift, vibration, and abnormal noise, which will seriously compromise driving safety.
