The invention relates to the technical field of air springs, and provides an air spring damping system, a vehicle and an air spring damping system control method.The air spring damping system comprises a cavity defined by an air bag, an upper end cover and a lower end cover jointly. The shock absorber and the isolation block are located in the cavity, one end of the shock absorber is connected with the upper end cover, the other end of the shock absorber is connected with the lower end cover, the isolation block divides the cavity into a spring cavity and a cooling cavity, and the cooling cavity is arranged on the periphery of at least part of the shock absorber in a surrounding mode. A first channel is formed in the lower end cover, one end of the first channel communicates with the cooling cavity, and the other end of the first channel communicates with the cooling medium. A cooling medium may enter the chamber to reduce the temperature of the air within the chamber. In this way, the low-temperature air in the cooling cavity can cool the shock absorber, so that the situations that the temperature of damping force of the shock absorber is reduced or the shock absorber fails to seal, leaks oil and the like due to the fact that the temperature of the shock absorber is too high are reduced or avoided, and the working stability and durability of the shock absorber can be effectively improved.

    本申请涉及空气弹簧技术领域,提供一种空气弹簧减振系统、车辆及空气弹簧减振系统控制方法,空气弹簧减振系统包括气囊、上端盖和下端盖共同围设形成的腔室。还包括位于腔室的减振器和隔离块,减振器的一端与上端盖相连,另一端与下端盖相连,隔离块将腔室分割为弹簧腔室和冷却腔室,冷却腔室围设在至少部分减振器的外周。下端盖上开设有第一通道,第一通道的一端与冷却腔室相连通,另一端与冷却介质连通。冷却介质可以进入腔室内,以降低腔室内空气的温度。这样冷却腔室内的低温空气便可以对减振器进行冷却降温,以减少或避免减振器因温度过高而使减振器出现阻尼力温衰或密封失效漏油等情况,能够有效提高减振器工作的稳定性和耐久性。
