The invention belongs to the field of engineering machinery, and discloses a disconnected axle assembly and an all-terrain crane, the disconnected axle assembly is used for being installed on a frame rotation section and comprises a left axle and a right axle, the left axle and the right axle are distributed on the two sides of the frame rotation section, and the left axle and the right axle are connected with the frame rotation section through respective suspension oil cylinders; and the wheel side driving motors are mounted in the left axle and the right axle and are used for rotationally driving the wheels on the two sides. The invention provides a disconnected axle assembly of an independent suspension and a wheel side hydraulic auxiliary driving system of the disconnected axle assembly. A mechanical drive axle and a wheel side hydraulic drive axle can be driven at the same time through a single engine. Compared with the prior art, the height of the whole vehicle can be reduced, the height of the gravity center can be reduced, the running anti-roll capacity is improved, running is safer, wheel edge liquid driving force can be increased, the dynamic property of the whole vehicle is improved, the wheel edge liquid driving force can be selectively input according to the running working condition of the vehicle, and control is flexible and convenient.

    本申请属于工程机械领域,公开了一种断开式车桥总成和全地面起重机,断开式车桥总成用于安装至车架回转段并包括左侧车桥和右侧车桥,分布于车架回转段的两侧,左侧车桥和右侧车桥分别通过各自的悬架油缸与车架回转段相连;轮边驱动马达,安装在左侧车桥和右侧车桥中并用于旋转驱动两侧车轮。本申请提供了一种独立悬架的断开式车桥总成及其轮边液压辅助驱动系统,可利用单个发动机同时驱动机械驱动桥及轮边液驱桥。与现有技术相比,可降低整车高度,降低重心高度,提高行驶抗侧倾能力,行驶更安全,可增加轮边液驱动力,提高整车动力性,还可根据车辆行驶工况,选择投入轮边液驱动力,控制灵活方便。
