Troubleshooting car shock absorber

To the shock frame and the rapid decay of the body, improve vehicle ride comfort and comfort, vehicle suspension systems generally are equipped with shock absorbers, the current car is a widely used two-way role of cylindrical shock absorber.

Shock absorber is the use of vehicles during the most easily damaged parts, shock absorbers work so good or bad, will directly affect the smooth driving of motor vehicles and other parts of life,
So we have to make long-term shock absorbers in good working condition.

The following are my many years of work on checking the state of shock absorber experiences and share with

1, press down firmly on the bumper, then release, if the car jumps about 3 times, then the note is in a good shock absorber.

2, when the car slowly driving and emergency braking, if the vehicle vibration more intense, indicating shock absorber problem.

3, poor road conditions, such as cars driving on the road about 10 km after the stop, hand-to-absorber case, if not hot enough, shows no resistance to the internal shock absorber, shock absorber does not work.
At this point, can be added to the appropriate lubricant, and then to test if the hot shell, internal shock absorber was in oil, should add a little oil; otherwise, indicating shock absorber failure.

4, to remove the vertical shock absorber, and the bottom of the folder in the vise on the connecting ring, pull lever press shock many times, now have a stable resistance, pull up and recovery, the resistance should be greater than
When downward pressure resistance, such as resistance to unstable or no resistance may be an internal shock absorber valve parts lacking fuel or damage should be repaired or replaced.

Determine the shock absorber, or if after the expiry of the time in question, first see whether there is leakage of the phenomenon of shock absorbers or traces of old oil spills.

If found to leak, tighten the first nut oil cylinder head, if the damper is still leaking, there may be oil seals, sealing washers failure, should be replaced with new seals. If it still can not eliminate
Leakage, shock rod should be pulled out if there was not a time card or severity, and then further examine the piston and cylinder is too large gap between, whether the shock absorber piston rod bending, piston rod
Whether the cylinder surface and scratch or pull marks.

If the damper does not leak phenomenon, should check the shock absorber connection pin, connecting rod, connecting hole, rubber bushings, etc. for damage, loose weld, break or fall off of the office. If the
Check above normal, should be further decomposed shock absorbers, check the piston and cylinder with the gap between it is too large cylinder with or without injury, the valve seal is good, the valve flap and valve seat is fit
Not tight, and the shock absorber spring is too soft Dilatation or broken, depending on the circumstances or for grinding parts to approach repair.

In addition, the shock absorber in the issue will appear in the actual use of the sound of failure, mainly due to shock absorbers and leaf springs, frame or shaft collide, damage or loss, and shock absorption pad
Device dust tube deformation, causes such as the oil shortage, the reasons should be identified, to be repaired.
