The hard and bumpy car shock absorber should be caused by the failure of the shock absorber. When the vehicle travels for a certain mileage or time, there will be certain oil stains on the surface of the shock absorber cylinder. But this does not mean that the shock absorber is leaking. It is just that there will be a certain amount of mud and sand on the damping stroke. It will look like an oil leak to a certain extent, but it will also cause the shock absorber to reappear if the oil leaks to a certain extent. Hard and bumpy. Generally, the failure of a shock absorber is judged based on factors such as the style of the shock absorber, the level of leakage, and the location of the oil trace.
Judgment method for failure of vehicle shock absorption:
1) Drive the vehicle on a road with poor road conditions for 10km and it feels hard and bumpy, and touch the shock absorber shell by hand. If it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work, as if there is no shock absorption effect. Appropriate lubricating oil can be added and the test can be carried out. If the effect is still not satisfactory, the shock absorber has failed.
2) When the car is driven slowly and braked urgently, if the car vibrates violently, and is hard and bumpy, it means there is a problem with the shock absorber.
3) Press the bumper firmly and then release it. If the car jumps 2 or 3 times, it means that the shock absorber is working well.
Hard and bumpy treatment methods for car shock absorption;
1) The shock absorber can be replaced. The main function of car shock absorption is to quickly attenuate the vibration of the body and frame, and improve the comfort of the car during driving.
2) The type of tire is also related to shock absorption. Softer tires have good shock absorption effects, but they are not wear-resistant. Wear-resistant tires are generally hard, but their comfort performance is very poor.
3) Both mechanical shock-absorbing seats and air-bag shock-absorbing seats can bring better shock absorption and improve driving comfort.
