The role of the car hem arm:
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.
The lower arm of the car is broken
The lower arm is an important part of the chassis suspension system of the car, which connects the body and the wheel flexibly, plays a role in slowing down the impact of the road surface during the vehicle driving, and ensures the comfort of the ride. When the lower arm fails, it will lead to reduced controllability and comfort, reduced safety performance, abnormal noise, inaccurate positioning parameters, deviation, abnormal wear or damage of other components, and even affected or faulty steering. Symptoms of lower arm failure include reduced controllability and comfort, reduced safety performance, abnormal sound, inaccurate positioning parameters, deviation, abnormal wear or damage to other components, affected steering or even failure.
The lower arm is a part of the multi-link suspension system, which can automatically adjust the camber Angle, the front beam Angle and the steering Angle of the rear wheel when the suspension is shrinking through different connecting rod configurations. Therefore, when the multi-link suspension system has a problem, it will also lead to the failure of the lower arm. If the lower arm fails, the vehicle's handling will be significantly affected, and the driving experience will be greatly reduced. In addition, the failure of the lower arm may also lead to vehicle deviation, abnormal wear or damage of other components, and even affected or disabled steering, which brings hidden dangers to driving safety.
In order to avoid lower arm failure, the owner should regularly check and maintain the vehicle's suspension system, especially the multi-link suspension system. If the lower arm is found to be faulty, it should be replaced in time to ensure the safety and controllability of the vehicle. In addition, the driver should also pay attention to avoid excessive driving or overload, so as not to increase the burden of the lower arm, resulting in failure. To sum up, the lower arm is an important part of the chassis suspension system, and the owner should pay attention to its maintenance and maintenance to ensure driving safety and driving experience.
What if the lower arm of the car is broken
1. Because the triangle lower arm belongs to the steering system, the rubber sleeve of the lower arm is broken, which directly leads to abnormal dynamic driving of the vehicle and deviation of the vehicle;
2. The wear gap has a large impact on direction control, which is very unfavorable to safety. It is recommended to go to the 4s shop for a comprehensive inspection, including the tires.
3. The principle of the lower arm of the car is to actively adjust the wheel positioning when the suspension is compressed through the constraint Angle design of the connected moving point. Because this design freedom is very large, it can be fully matched and adjusted for the model. Overall, the multi-link suspension maximizes tire grip and improves vehicle handling.
The lower arm of the car is connected to the "horn" of the wheel and the subframe to fix and support the wheel. After the lower arm is damaged, it will show that the tire will swing abnormally when the vehicle is driving, resulting in abnormal tire wear, and the noise is relatively large. This is because the lower arm belongs to a part of the steering system of the vehicle, and the damaged lower arm will cause the dynamic running of the vehicle to be abnormal, and the vehicle will run off or even lose control. It is recommended to go to the 4S shop as soon as possible.
