How the car control arm works :
The automobile control arm (also known as the swing arm) is the guidance and force transmission element of the automobile suspension system, and its main role is to transfer various forces acting on the wheel to the body, while ensuring that the wheel moves according to a certain track. The control arm connects the wheel and body together flexibly through the ball head and rubber sleeve, ensuring the stability and handling of the vehicle
Automotive control arms are typically made of a variety of materials, including cast aluminum, forged aluminum, cast iron, and stamped steel. For example, the lower control arm of some models is made of low-carbon stamped steel plate with high yield strength and tensile strength to ensure its rigidity and strength
In addition, lightweight materials such as aluminum alloy are also widely used to reduce vehicle weight and improve fuel efficiency
