[0002] There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market of auto parts is becoming larger and larger. In recent years, auto parts manufacturers have also developed rapidly. The suspension system is an important part of the vehicle and has a great influence on the driving smoothness and handling stability of the vehicle. As the guiding and force transmission element of the vehicle suspension system, the control arm transmits various forces acting on the wheel to the body, while ensuring that the wheel moves along a certain trajectory, and its layout and structural dimensions directly determine the motion characteristics and ride comfort of the suspension system. The front mounting bracket of the lower control arm of the front suspension of the car is a frequently used device in the automotive industry.
