Axle assemblies for low chassis vehicles are described herein. The axle assembly includes an axle housing and a drive unit for driving the wheel assembly. The axle housing includes a first gearbox, a second gearbox, and a bracket assembly coupling the first gearbox to the second gearbox. The axle assembly includes a first hub assembly and a second hub assembly forming a first axis of rotation. The first gearbox includes an electric motor coupled to a transmission for rotating the output shaft. The first gearbox also includes a differential mounted for rotation with the transmission and a first reduction box mounted for rotation with the differential. The axle assembly also includes a portal axle mounted to rotate with the first reduction box and extending from the first gearbox to the second gearbox, where the portal axle forms a second axis of rotation that is offset relative to the first axis of rotation of the hub assembly. The second gearbox includes a second reduction box mounted for rotation with the portal axle and adapted to drive the second hub assembly.
本文描述了用于低底盘车辆的车桥组件。车桥组件包括车桥壳体和用于驱动车轮组件的驱动单元。车桥壳体包括第一齿轮箱、第二齿轮箱和将第一齿轮箱耦合至第二齿轮箱的托架组件。车桥组件包括形成第一旋转轴线的第一轮毂组件和第二轮毂组件。第一齿轮箱包括电动马达,该电动马达耦合至用于旋转输出轴的变速器。第一齿轮箱还包括安装成随着变速器旋转的差速器和安装成随着差速器旋转的第一降速箱。车桥组件还包括安装成随着第一降速箱旋转并从第一齿轮箱延伸到第二齿轮箱的门式车桥,其中,门式车桥形成第二旋转轴线,该第二旋转轴线相对于轮毂组件的第一旋转轴线偏移。第二齿轮箱包括第二降速箱,该第二降速箱被安装成随着门式车桥旋转并且适合于驱动第二轮毂组件。
