If it is broken, the symptoms are as follows: the handling and comfort are reduced; Reduced safety performance (such as steering and braking); Abnormal sound (sound); Improper positioning parameters, deviation and wear or damage of other components (such as tire wear); Turn to a series of problems such as being affected or even failing.
Extended data:
The lower arm is a mechanical tool, which means multi-link suspension. Multi-link suspension completely solved this problem. Through different connecting rod configurations, the camber and toe angle of the suspension can be automatically adjusted when it contracts, and the rear wheel can obtain a certain steering angle.
Suspension system refers to the whole support system composed of springs and shock absorbers between the car body and the tires. The correct function of suspension system is to support the car body and improve the riding feeling. Different suspension settings will make drivers feel different.
The lower swing arm, one of the swing arms on the car, is mainly used to support the car body and shock absorber and buffer the vibration during driving. The shock absorber can play a good auxiliary role in the lower suspension. Its tacit cooperation with shock absorber and spring can form a complete suspension system. The lower arm is responsible for supporting the weight and steering, and the lower arm is fixed with a rubber sleeve and connected with a shock absorber.
