1. The lower arm of the vehicle is an important component of the chassis suspension system. It connects the body and the vehicle elastically. When the vehicle is running, the axle and the frame are elastically connected through the lower arm, so as to reduce the impact (force) caused by the road during driving, so as to ensure the ride comfort;
2. Attenuate the vibration caused by the elastic system and transmit the reaction force and torque from all directions (longitudinal, vertical or lateral), so as to make the wheel move relative to the vehicle body according to a certain track and play a certain guiding role;
3. Therefore, the lower arm plays a very important role in the comfort, stability and safety of the vehicle. It is one of the very important components of modern automobile.
