What is the chassis suspension control arm?

The chassis suspension control arm (also known as the control arm) is an important component that connects the car chassis and wheels, usually made of metal material. The control arm is mainly composed of one of the geometric links in the vehicle suspension system, which is used to locate or control the position and motion of the wheels.

The most common types of control arms are upper and lower control arms and front and rear control arms. The upper and lower control arms are usually connected to the wheels and the upper part of the vehicle, which can control the vertical movement of the wheels within the range of the suspension system. The front and rear control arms are connected to the wheels and position the forward and backward movement of the wheels to ensure that the vehicle remains stable when driving in a straight line and can better control the vehicle when turning.

By adjusting the length, angle, and connection points of the control arm, the position and movement of the wheels in the suspension system can be changed, thereby affecting the vehicle's suspension and driving performance. The control arm plays a crucial role in the suspension system of a vehicle, therefore its design and performance directly affect the stability, comfort, and safety of vehicle operation.
