The invention relates to a liftable axle type suspension driving system assembly and a multi-axle electric vehicle. The liftable axle type suspension driving system assembly comprises an axle, an independent suspension, a driving motor and a lifting arm, one end of the lifting arm is a resistance end acting on the axle or the independent suspension, and the other end of the lifting arm is a powerend which is stressed to enable the lifting arm to drive the axle to ascend. A lifting air bag is arranged between a frame and the power end of the lifting arm and used for applying force to the powerend of the lifting arm; the independent suspension includes a suspension airbag that deflates when the lift arm lifts the axle and inflates when the lift arm does not lift the axle. By arranging thelifting arm and the independent suspension, when the vehicle is in a non-full-load state, a plurality of wheels can be lifted, the number of used drive axles is reduced, energy consumption is reduced,and meanwhile tire abrasion is avoided; the problems that when an existing multi-axle electric vehicle adopts multi-axle driving, energy consumption is high, tires have unnecessary abrasion, and thevehicle using cost is increased are solved.

    本发明涉及可提升车轴式悬架驱动系统总成及多轴电动车辆。可提升车轴式悬架驱动系统总成包括车桥、独立悬架、驱动电机、提升臂,提升臂一端为作用在与车桥或者独立悬架上的阻力端,另一端为受力使提升臂带动车桥升起的动力端;提升气囊设置在车架与提升臂的动力端之间,用于对提升臂的动力端施力;独立悬架包括在提升臂提升车桥时放气在不提升车桥时充气的悬架气囊。通过设置的提升臂和独立悬架,在车辆处于非满载的状态下,可以将若干个车轮提升起来,减少驱动桥的使用数量,节约能耗,同时避免轮胎磨损,解决了目前的多轴电动车辆采用多轴驱动时存在能耗高、轮胎存在不必要磨损造成的用车成本增加的问题。
