Yutian brand shock absorber maintenance

In order to make the frame and body vibration attenuation rapidly, to improve the car's comfort and comfort, the automobile suspension system equipped with shock absorber commonly, on car is widely used in the two-way cartridge damper.Shock absorber is the vulnerable parts in the process of car use, shock absorbers work is good or bad, will directly affect the service life of the car moving stationarity and other parts, so we should often make the shock absorber is in good working condition. The following methods can be used to check whether the shock absorber works well.

Haneda brand shock absorber detection includes shock absorber performance test, shock absorber durability test, shock absorber dual shock test

All kinds of shock absorbers are tested by power indicator test, friction test and temperature characteristic test.



After determining the problem or failure of the haneda brand shock absorber, we should first check whether the shock absorber has oil leakage or traces of old oil leakage.

Oil seal washer, seal washer broken damaged, oil storage cylinder head nut loose. May be oil seal, seal washer damage failure, should replace the new seal. If still can't eliminate the oil spill, should pull out of the shock absorber, if feel the hairpin or weight, will have a further check whether the clearance between the piston and cylinder is too large, haneda brand shock absorber piston connecting rod with or without bending, the piston connecting rod surface and the cylinder have scratches or marks.

If the haneda brand shock absorber does not leak oil, it shall check whether the shock absorber connection pin, connecting rod, connecting hole, rubber liner, etc. are damaged, welded off, cracked or detached. 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 haneda brand or broken, grinding according to the circumstance or change a way to repair.

In addition, the shock absorber in be used actually appear noise fault, this is mainly due to the shock absorber with steel plate spring, frame, or shaft collide, rubber gasket damage or loss and shock absorber dust drum deformation, caused the oil shortage, should find out the reason, to be repaired.

After inspection and repair, the shock absorber shall conduct performance test on a special test bench. When the resistance frequency is between 100 and 1mm, the stretch stroke and compression stroke resistance shall meet the requirements. For example, the maximum drag of CAl091 stretch stroke is 2156~2646N, and the maximum drag of compression stroke is 392~588N. The maximum drag of the stretch stroke of the east windmill is 2450~3038N, and the maximum drag of the compression stroke is 490~686N.

If there is no test condition, we can also adopt a kind of experience, with an iron rod through the shock absorber in the bottom rings, with his feet on the side, holding the rings on the reciprocating 2 ~ 4 times, when pull up resistance is very big, pressing down on them without taxing, and stretching resistance compared with before repairing recovered, no idle, indicates basic normal shock absorber.
