Shock absorbers also need to pay attention to carefully repair and maintenance In order to make the frame and body vibration rapid decay, improve vehicle ride comfort and comfort, the vehicle suspension systems are generally equipped with shock absorbers, is currently widely used in the car is double-acting telescopic shock absorber. Automobile shock absorber is used in the process of wearing parts, shock absorbers work is good or bad, will directly affect the stability and other parts of the life of cars so we should make the shock absorbers are often in good working condition. The following methods can test the shock absorbers work is good. 1, so that cars on the road in poor condition after driving 10km road parking, touch shell shock absorber, if not hot enough, indicating no resistance inside the shock absorber, shock absorbers do not work. At this point, you can add the appropriate oil, then test, if the housing fever, shock absorbers, compared with an internal oil, should add enough oil; otherwise, indicating shock absorber failure. 2, press firmly on the bumper, and then release, if the car has 2 to 3 times jump, then the shock absorbers work well. 3, when the car is slowly driving and emergency braking autel maxidas ds708 coverage, if the car more violent vibration indicating a problem with the shock absorber. 4, remove the shock absorber to be upright, and the lower end of the connecting ring clamp on the vise, pull compression damping lever several times, then there should be a stable resistance, pull up (recovery) should be greater than the resistance to resistance when under pressure, such as resistance to unstable or no resistance, it may be short of oil or internal shock absorber valve parts damage should be repaired or replaced parts. In determining the shock absorbers have a problem or failure; it should first check whether the shock absorber oil spills or traces of old oil spills. Seal gaskets, gasket rupture damaged oil storage cylinder head nut loose. May be oil seals, seal washers failure, should be replaced with new seals. If you still can not eliminate leakage, shock absorbers should be pulled out, if they feel there is no issuer or the severity of the moment, and further examination clearance between the piston and cylinder is too large, whether the damper piston rod bent piston rod cylinder surface and if there is scratched or pull marks. If there is no leakage phenomenon shock absorbers, shock absorbers should check the connection pins, connecting rods, connecting hole, rubber, bushings and other damage, sealing off, break or fall off place. If these were normal, it should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without strain, the valve seal is good, valves and valve seat are tight fitting and minus Zhen's done spring is too soft or broken, take grinding repair or replace parts of the way under the circumstances. In addition, the shock absorber in actual use will be issued by the sound of failure, which is mainly due to the shock absorbers and springs, frame or shaft collision damage or loss, and shock absorber pad dust tube deformation, oil lack of other causes, reasons should be identified, to be repaired. After the shock absorber during the inspection repair should be carried out in a special test bench performance test, when resistance frequencies 100 ��1mm, its resistance to stretching and compression stroke shall comply with the provisions, indicating damper normal.
