What is the abnormal reaction of car shock absorber?

- Jan 11, 2018 -

A lot of people know the car shock absorber, but many people don't know what car shock absorber check the, work normal car shock absorber, can alleviate the impact of the road for the car, quickly absorb its turbulence, the vehicles are driven back to normal state;

How would an abnormal car shock absorber react?

Automobile shock absorber, just as its name implies is to slow down the car on the road in the sense of shock, with professional, is to make the vibration of the frame and body belongs to decay quickly, to improve the car's comfort and comfort, the automobile suspension system, suspension system is to point to by springs and shock absorbers between body and tire of the whole support system) is generally equipped with shock absorber, the car is widely used in the two-way cartridge damper.

How would an abnormal car shock absorber react?

Automobile shock absorber, just as its name implies is to slow down the car on the road in the sense of shock, with professional, is to make the vibration of the frame and body belongs to decay quickly, to improve the car's comfort and comfort, the automobile suspension system, suspension system is to point to by springs and shock absorbers between body and tire of the whole support system) is generally equipped with shock absorber, the car is widely used in the two-way cartridge damper.

Method 1: make the car stop after 10km on the road with poor road condition, and touch the shell of shock absorber with the hand. If it is not hot enough, there is no resistance inside the shock absorber, and the shock absorber does not work.

At this point, the appropriate lubricating oil can be added and then tested. If the shell is hot, the oil in the shock absorber should be filled with sufficient oil.

Otherwise, the shock absorber fails.

Method 2: press the bumper, then release, if the car has 2~3 jumps, the shock absorber works well, otherwise the work is not very normal.

Method 3: when the car is moving slowly and emergency braking, if the car vibration is more intense, it means that the shock absorber work is abnormal.

Method 4: remove the shock absorber to the upright, and connect the bottom ring clamp on the vise, pull reduce vibration lever several times, this time should be stable resistance, pull up resistance should be greater than the resistance when pressing down on them, such as unstable resistance or without resistance, may be internal lack of oil damper or valve parts damaged, should be repaired or replacement parts.

After determining the problem or failure of the shock absorber, the first thing to check is whether the shock absorber has oil leakage or the trace or phenomenon of old oil leakage.

Oil seal gasket, seal ring rupture damage, storage cylinder cover nut loose.

May be oil seal, seal gasket damage failure, should replace the new seal.

If still can't eliminate the oil spill, should pull out of the shock absorber, if feel or not at that time, will have a further check whether the clearance between the piston and cylinder is too large, with or without shock absorber piston rod bending the piston connecting rod surface and the cylinder have scratches or marks.

If the shock absorber does not have oil leakage, it should check whether there is any damage, dissoldering, rupture or falling off of the shock absorber connection pin, connecting rod, connection hole, rubber bushing and so on.

If the above check is normal, should be further decomposed shock absorber, check whether the fitting clearance between the piston and cylinder is too large, a cylinder with and without strain, valve seal are in good condition, whether the disc and seat nicely, and whether the presence of shock absorber spring is too soft, or broken, grinding according to the circumstance or change a way to repair.

Finally, shock absorber in be used actually there will be noise fault, this is mainly due to the shock absorber with steel plate spring, frame, or axis, as a result of the collision deformation of rubber gasket damage or loss, and shock absorber dust drum, caused the oil shortage, should find out the reason, to be repaired.

The normal work of the shock absorber can ensure more smooth progress during driving, so it is necessary to check whether the shock absorber works properly.
