The role of the rear hem arm of the car.
The function of the rear hem arm is to support the body and shock absorber. And buffer the vibration during driving. The shock absorber can play a very good auxiliary role in the lower suspension. Its tacit cooperation with the shock absorber and the spring can constitute a complete suspension system.
1, the lower arm is commonly known as the lower suspension. Its main function is to support the body, shock absorber and buffer the vibration in the driving, shock absorber can play a very good auxiliary role on the lower suspension;
2. The tacit cooperation of shock absorber and spring can form a set of excellent suspension system. The rubber sleeve of the lower swing arm is broken, and the ball head of the lower swing arm is broken, and the swinging arm is replaced.
3, suspension guidance and support, its deformation affects wheel positioning, reduce driving stability, if there is a problem with the front swing arm, the feeling is that the steering wheel will shake, and hands loose the steering wheel is easy to run off, and high speed when difficult to master the direction.
Its main function is to support the driving vibration of the body, shock absorber and buffer, the shock absorber can play a very good auxiliary role on the lower suspension, and its tacit cooperation with the shock absorber and the spring, thus forming a set of excellent suspension system.
The lower swing arm is the guide and support of the suspension, and its deformation affects the wheel positioning and reduces the driving stability.
Car hem arm rust is indeed a common phenomenon, usually does not cause too much problems to the performance of the car. However, if you find that the hem arm is severely rusted, it may need to be treated accordingly to prevent it from affecting the car's suspension system. The lower arm of the car, also known as the lower suspension, its main function is to support the body of the car and alleviate vibration during driving. The shock absorber has played a great auxiliary role, and through the close coordination with the spring, they together constitute an excellent suspension system. In addition, the lower swing arm is also the guide and support of the suspension system, and its deformation may affect the wheel positioning, resulting in reduced driving stability. An obvious sign is that when the current swing arm has a problem, the steering wheel will shake, and the vehicle is easy to run off after loosening the steering wheel, and it may be difficult to master the direction when driving at high speed. If there is a problem with the rubber sleeve of the lower swing arm, you can directly replace the rubber sleeve, if there is a problem with the ball head of the lower swing arm, you need to replace the lower swing arm. In normal road conditions, the life of the lower arm is generally between 80,000 km and 250,000 km. However, this value is also affected by driving road conditions, such as poor road conditions may shorten the service life of the lower swing arm. In general, although the rust of the lower arm of the car is a normal phenomenon, if serious rust is observed or the above mentioned problems occur during driving, it still needs to be dealt with in time to avoid affecting the normal use of the car.
What symptom does the vehicle swing arm break?
The symptoms of a broken swing arm are:
1. The vehicle swing arm is broken, resulting in reduced controllability and comfort;
2, the vehicle swing arm is broken, resulting in reduced safety performance (such as steering, braking, etc.);
3, the vehicle swing arm is broken, resulting in abnormal noise on one side of the road;
4. The vehicle swing arm is broken, resulting in inaccurate positioning parameters and deviation;
5, the vehicle swing arm is broken resulting in other parts wear or damage;
6, the vehicle swing arm is broken, resulting in affected or faulty steering. The left and right senses are inconsistent and difficult to manipulate.
7, the vehicle swing arm is broken resulting in other parts wear or damage ring (such as tire wear).
