Detailed shock absorber maintenance knowledge
Automobile shock absorber bad what symptom is there? Shock absorber is cars used in the process of wearing parts, shock absorber work is good or bad, will directly affect the driving stationarity and other parts of life, therefore, we should the shock absorber is often in good working condition. The following methods can be used to test the shock absorber is good.
1, to make the car in poor condition of roads on the road speed of 10 km after parking, touch the shock absorber shell, if isn't hot enough, no resistance in the shock absorber and shock absorber does not work. At this time, adding proper lubricating oil, then the test, if the shell is internal fever, shock absorber oil, should add enough oil, otherwise, the damper failure.
2, press the bumper, then release, if the car jump is not more than one or two times, the shock absorber works well. I constantly look very resilient to bow and scrape, it is bad.
3, when the car is slow and emergency braking, if the car vibration is more severe, there is a problem that the shock absorber.
4, demolition under the shock absorber will the upright, and the lower end of the connecting ring clamped in a vise, pull hard pressure damping rod several times, at this time should have a stable resistance, to pull the restoration of resistance should be greater than the downward pressure resistance, such as resistance is not stable or no resistance may is shock absorber internal lack of oil or valve parts damaged, repair or replacement of parts.
Shock absorber if the oil spill how to do?
In determining the shock absorber has a problem or failure, should first check whether the shock absorber oil spills or traces of old oil spills.
If oil is found, first tighten the oil cylinder head nut, if the shock absorber still leak may is an oil seal, gasket is damaged, should be replaced with a new seal. If you still can not eliminate oil leakage should be pulled out of the damping rod, if feel a hairpin or weight not only for a moment, and then further examination between the piston and cylinder gap is too large, a shock absorber piston connecting rod without bending, surface of the piston rod and the cylinder if there is a scratch or stretch marks.
If the shock absorber no oil leakage phenomenon, should check shock absorber connecting pin, connecting rod, connecting hole, a rubber bushing etc. if there is damage, sealing off, rupture, or off the place. If the normal examination of the above, it should be further decomposed shock absorber, check the piston and cylinder with the gap is too large, the cylinder with or without strain, valve seal is good, valve flap and the valve seat fitting is tight, and shock absorber of the tensile spring is too soft or broken, according to the circumstances to take grinding or changing the way the parts repair.
In addition, shock absorber in actual use will rattle the fault, which is mainly due to the shock absorber and the steel plate spring and frame or shaft of the collision, the rubber pad damage or loss and damper dust-proof cylinder deformation, caused by insufficient oil should be to identify the reasons, to be repaired.
