WG1642430282 howo shock absorber is suitable for SINOTRUK and other heavy duty brand trucks. Especially for HOWO, HOWO A7, STEYR and so on. china howo truck co.,limited is mainly produce and sale sinotruk howo genuine truck parts.

In order to quickly attenuate the vibration of the frame and the body, and improve the smoothness and comfort of the car, the car suspension system is generally equipped with shock absorbers, and the two-way-acting cylinder shock absorber is widely used in the car.

WG1642430282 Shock absorber is a vulnerable part in the process of car use. The working quality of the shock absorber will directly affect the smoothness of the car and the life of other parts. Therefore, the shock absorber should always be in good working condition.
Fault checkMake the truck stop after driving 10km on the road with poor road conditions and touch the shock absorber shell with your hands. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then test, if the shell is hot, it means that the shock absorber is short of oil, and enough oil should be added; otherwise, the shock absorber has failed.

Press the bumper firmly and then release it. If the car jumps 2 or 3 times, it means that the shock absorber is working well.

When the car is driving slowly and braking urgently, if the car vibrates violently, it indicates that there is a problem with the shock absorber.

Remove the shock absorber and stand it upright, and clamp the lower end connecting ring on the vise, and then forcefully pull the shock absorber rod several times. At this time, there should be stable resistance, and the resistance of pulling upwards should be greater than when pressing downwards. If the resistance is unstable or no resistance, it may be due to lack of oil inside the shock absorber or damage to the valve parts. Repair or replacement parts should be carried out.

malfunction repair

After determining that the shock absorber is faulty or invalid, first check whether the shock absorber is leaking or has traces of old oil leakage.

The oil seal washer and sealing washer are broken and damaged, and the oil storage cylinder head nut is loose. It may be that the oil seal and sealing gasket are damaged and invalid. Replace with new seals. If the oil leakage still cannot be eliminated, pull out the shock absorber. 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.

If the WG1642430282 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 clearance 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 shock is too soft or broken, it should be repaired by grinding or replacing parts according to the situation.

In addition, the shock absorber may have noise failure in actual use, which is mainly caused by the shock If it is caused by insufficient or other reasons, the cause shall be found out and repaired.

After the WG1642430282 shock absorber is inspected and repaired, the performance test should be carried out on a special test bench. When the resistance frequency is 100±1mm, the resistance of the extension stroke and compression stroke should meet the requirements. For example, the maximum resistance of Jiefang CA1091’s extension stroke is 2156~2646N, the maximum resistance of compression stroke is 392~588N; the maximum resistance of howo Motor’s extension stroke is 2450~3038N, and the maximum resistance of compression stroke is 490~686N. If there is no test condition, we can also adopt an empirical method, which is to use an iron rod to penetrate the lower end of the shock absorber ring, step on the two ends of the shock absorber, and hold the upper ring with both hands and pull it back and forth 2~4 times. The resistance is great when you pull up, and you don’t feel any effort when you press down, and the resistance of stretching is restored compared to before repair, and there is no sense of empty travel, which indicates that the shock absorber is basically normal.
