To make the vibration frame and the rapid decay of the body, improve electric vehicle ride and comfort, the electric vehicle suspension systems are generally equipped with shock absorbers, is currently widely used in the car is dual acting telescopic shock absorbers.

Shock absorbers are used in the process of electric vehicles vulnerable parts maxidiag elite md802, shock absorbers work is good or bad, will directly affect the stability and other parts of the life of the steam electric cars so we should make the shock absorbers are often in good working state. The following methods can test the shock absorbers work is good.

1, so that the poor condition of the car on the road 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 lubricant, and then test, if the shell fever, compared with an internal shock absorber oil, should add a little oil; otherwise, indicating damper failure.

2, Press firmly bumper, then release, if the car has a 2 to 3 times jump, then the shock absorbers work well.

3, When the electric car slowly driving and emergency brake 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 in the vise clamp, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than the downward pressure when resistance, such as resistance to unstable or no resistance, may be short of oil dampers or valves inside the damaged parts should be repaired or replaced parts.

In determining the shock absorbers have a problem or damaged, 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. Probably 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 check 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 oil leakage phenomenon shock absorbers autel maxisys pro, shock absorbers should check the connecting pins, connecting rods, connecting hole, rubber, bushings and other damage, sealing off, break or fall off place. If the examination is normal, 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 less shock absorbers done spring is too soft or broken, take grinding way to repair or replacement under the circumstances.

Further, the electric car shock absorbers will appear in the actual use of beeps failure, which is mainly due to the damper spring, frame or shaft collision damage or loss, and a cushion damper dust tube deformation, oil shortage causes such 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 the resistance when frequency 100 1mm, its resistance to stretching and compression stroke should comply, indicating normal shock absorber.

Some good car diagnostic tools can help you test your car by yourself, such as:
