Unlike most currently used conventional car immutable height compared to a coil spring suspension system, the air suspension system can be adjusted up or down depending on the ride height of the undulation of the road, so that the vehicle can adapt to various road conditions, driving needs. For purposes of this design, the air suspension system is frequently used for off-road vehicles traveling in bad road conditions, to ensure that the vehicle can smoothly pass through the mud, wading, gravel roads and the like. Air suspension system is a very advanced and practical configuration, but very ldquo; fragile rdquo ;.
Since the system structure is complicated, and its failure probability is much higher than the frequency of the coil spring suspension system, the air is used as the chassis height adjustment ldquo; rdquo ;, propulsion sealing damper We need to be further improved, if the air damper there is leakage, the entire system will be in ldquo; paralysis rdquo; state. And if the ride height adjustment frequently, and may result in local overheating pump system, it will greatly shorten the life of the pump.
