A control arm is a crucial component of a vehicle's suspension system, connecting the wheel to the vehicle's chassis. Its primary function is to control the wheel's movement, allowing it to move up and down while maintaining its proper alignment with the body of the vehicle.
Control arms typically come in pairs: an upper control arm and a lower control arm. They can be designed in various shapes and made from different materials to meet specific performance needs. By controlling the wheel's motion, control arms help the vehicle better respond to uneven road surfaces, providing a smoother driving experience and improving handling and safety. Additionally, control arms assist in absorbing impacts from the road, reducing the direct effects on the vehicle's body.
In summary, control arms play a vital role in the suspension system, contributing significantly to driving comfort and safety.
