Regular inspection of car shock absorbers to improve travel safety factor
Automobile shock absorber is one of the key parts of the car body, which is very important for driving safety. After driving for a period of time, car shock absorber manufacturers must be inspected and repaired and maintained in time.
If an automobile shock absorber leaks oil, it is undoubtedly a very dangerous thing for the shock absorber. Then, once an oil leak is discovered, timely remedial measures must be taken. The key inspection items are oil seal gaskets, sealing gaskets ruptured and damaged, and oil storage cylinder heads. Check whether these parts have loose nuts.
If oil leakage is found, first tighten the cylinder head nut. If the shock absorber still leaks, the oil seal and gasket may be damaged and invalid, and new seals should be replaced. If the oil leakage still cannot be eliminated, pull out the damping rod. If you feel a hairpin or change in weight, check whether the gap between the piston and the cylinder is too large, whether the piston connecting rod of the shock absorber is bent, and the piston connecting rod Whether there are scratches or pull marks on the surface and cylinder.
Regularly check the car shock absorber to ensure driving safety. If the shock absorber does not leak oil, check the shock absorber connecting pin, connecting rod, connecting hole, rubber bushing, etc. for damage, desoldering, cracking or falling off.
If the above inspection is normal, the shock absorber should be further disassembled to check whether the matching gap between the piston and the cylinder is too large, whether the cylinder is strained, whether the valve seal is good, whether the valve clack and the valve seat are tightly attached, and whether
Whether the extension spring of the vibrator is too soft or broken, it should be repaired by grinding or replacing parts according to the situation.
In addition, the shock absorber will have a noise failure in actual use, which is mainly due to the shock of the shock absorber colliding with the leaf spring, the frame or the axle, the rubber pad is damaged or falling off, and the shock absorber dust tube
Deformation, lack of oil and other reasons should be found out and repaired.
After the shock absorber is inspected and repaired, the performance test should be carried out on a special test bench to ensure that the repair effect is intact and normal use.
