Damping gear is a fragile part of the car. The work of the damping gear will directly affect the stability of the car and the life of other parts. Therefore, the damping gear should be in good working condition. The following methods can be used to check whether the damping gear is working well.

Regular maintenance Damping gear and maintenance:

1. After driving 10 kilometers on a poor road, the car stopped. Touch the damper gearbox with your hand. If the temperature is not high enough, it means that there is no resistance inside the damping gear and the damping gear does not work. At this time, appropriate lubricating oil can be added and then tested. If the housing becomes hot, the damping gear is short of oil and enough oil should be added. Otherwise, it indicates that the damping gear has failed.

2. Press the bumper firmly and then release it. If the car bounces 2 or 3 times, it means that the damper is working properly.

3. When the car is decelerating and braking urgently, if the car vibrates violently, it indicates that there is a problem with the damping gear.

4. Remove damping gear to make it upright, then clamp the lower connecting ring on the vise, pull the damping rod several times, and then there should be stable resistance, upward (recovery) The resistance should be greater than the downward resistance. Pressure such as unstable resistance or no resistance may be caused by lack of oil inside the damping gear or damage to the valve parts. Parts should be repaired or replaced.

Therefore, after reading the daily maintenance and maintenance of the damping gear in this article, it should be noted that the damping gear will have noise failure in actual use, which is mainly due to the damping gear. It is caused by the collision with the leaf spring, the frame or the shaft, and the rubber pad is damaged or fallen off, and due to the deformation of the damping gear dust tube, insufficient oil and other reasons. Should be identified and repaired. After the inspection and maintenance of the damping gear, the performance test should be carried out on a special test bench. When the resistance frequency is 100 ±1mm , the resistance of extension stroke and compression stroke should meet the requirements, indicating that damping gear is basically normal.
