Briefly talk about the problem of oil leakage of Haval shock absorbers

 TIME:2020-05-25 09:23:35 

KAZOKU shock absorber is a kind of automobile shock absorber, which is mainly used to suppress the shock and the impact from the road surface when the spring rebounds after shock absorption. The existence of shock absorbers is mainly to cushion the vibration from the ground and improve comfort. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jump.

    The working principle of the Haval shock absorber is that when there is relative motion between the frame (or body) and the axle, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly passes through a cavity Different pores flow into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into the heat energy of the oil, and then absorbed by the shock absorber and emitted into the atmosphere. When the oil channel cross-section and other factors remain unchanged, the damping force increases and decreases with the relative movement speed between the frame and the axle (or wheel), and is related to the oil viscosity.

    There are two main types of oil leakage in Haval shock absorbers: slight oil leakage and severe oil leakage. The slight oil leakage shows that there is a small amount of oil on the shock absorber, but it does not affect the comfort of the vehicle. It is no different from the normal shock absorber. This oil leakage can be dispensed with first, but pay attention to oil leakage. More serious oil leakage means that there is a lot of oil sludge on the shock absorber. The shock absorption oil leakage will make the vehicle's shock absorption effect worse, seriously affecting the driving comfort, and sometimes accompanied by "squeaking" abnormal noise on bumpy roads And, if the oil leakage is particularly serious, the shock absorption will fail, and it will cause the vehicle to deviate.

    In fact, the oil leakage of the Haval shock absorber does not mean that the KAZOKU shock absorber needs to be replaced, but the damping performance of the KAZOKU shock absorber needs to be tested. If the damping performance is not close, it needs to be replaced in time. When replacing the shock absorber, a pair needs to be replaced.
