High quality OEM 500301936 98445861 99465083 truck shock absorber for IVECO chassis

Cylindrical shock absorber: When the vehicle encounters bumps during driving, the vibration generated by the wheels is transmitted to the shock absorber through the suspension system. The piston rod of the shock absorber moves upward, and the oil above the piston enters the chamber below the piston through the flow valve. At the same time, the compression valve opens, and part of the oil flows into the oil storage cylinder. When the piston rod moves downward, the oil below the piston returns to the chamber above the piston through the extension valve. The compensation valve is responsible for replenishing the oil to maintain the oil balance in the shock absorber. Through the flow of this oil and the control of valves, the shock absorber converts the vehicle's vibration energy into heat energy and dissipates it, thereby achieving the purpose of shock absorption.
Airbag shock absorber: During vehicle driving, the airbag shock absorber automatically adjusts the air pressure in the airbag according to road conditions and vehicle load. When the vehicle passes over a raised road surface, the airbag is compressed, the gas pressure increases, and the shock absorber generates an upward supporting force to slow down the impact of the vehicle. When the vehicle passes over a sunken road surface, the airbag returns to its original state under its own elasticity, the gas pressure decreases, and the shock absorber provides a downward pulling force to maintain the stability of the vehicle.
