The invention provides a commercial vehicle lightweight air suspension lifting device and method and a vehicle. The commercial vehicle lightweight air suspension lifting device comprises a vehicle frame, and a rear air cylinder, a lifting axle and a rear air bag are connected to a part close to the tail of the vehicle frame; the lifting axle is connected with the frame through a rear swing arm anda rear support, and the rear swing arm can rotate around the center of the rear support; a drive axle is arranged close to the front part of the frame; bearing air bags are symmetrically arranged onthe two sides of the drive axle; and a tail beam is arranged at the tail part of the frame and is used for supporting the air suspension. The bearing air bags on the two sides of the lifting bridge have the bearing and lifting effects at the same time, and compared with the technical state that small-capacity lifting air bags are additionally arranged, the number of the air bags is reduced, valvesand control pipelines attached to the additionally-arranged air bags are reduced, the overall reliability of the suspension can be improved, and later maintenance cost can be reduced; compared with the technical state of replacing the middle air bag by removing the bearing air bag, the bearing capacity of the double-side air bags is higher, the limited arrangement space is saved, and the drivingstability under the heavy-load working condition is better.

    本发明提供一种商用车轻量化空气悬架提升装置、方法及车辆,包括:车架,靠近车架尾部的位置连接有后储气筒、提升桥和后气囊;提升桥通过后摆臂和后支座与车架连接,后摆臂可绕后支座中心旋转;靠近车架前部位置安装有驱动桥;驱动桥的两侧对称布置承载气囊;车架的尾部设置有尾梁,尾梁为空气悬架提供支撑。提升桥两侧的承载气囊同时具备承载与提升作用,与额外增设小容量提升气囊的技术状态相比,减少了气囊数量,减少了增设气囊附带的阀类及控制管路,可提高悬架整体可靠性,有助于降低后期维护成本,与去掉承载气囊改换中置气囊技术状态相比,双侧气囊承载能力更强,节省有限布置空间,且重载工况下的行车稳定性更好。
