    摘要： A drive axle assembly for a low floor vehicle utilizes a single input gear assembly to drive a pair of laterally spaced wheel ends. The input gear assembly is positioned next to one of the wheel ends so that the vehicle floor can be lowered to facilitate passenger access to the vehicle. Each wheel end includes a gear reduction assembly with a ring gear rotatably mounted within a gear housing. A drive gear is operatively coupled to the input gear assembly and is in meshing engagement with the ring gear. The gear reduction assembly also includes an output or driven gear, which is larger than the drive gear, to provide the desired gear reduction. The driven gear is also in meshing engagement with the ring gear. A pair of idler gears is rotatably mounted within the gear housing and are in meshing engagement with both the drive and driven gear. The idler gears and drive gear do not have a common centerline. The assembly thus provides toothed contact via three gear sets combinations, which equalizes loading and eliminates the need for support bearings for the drive and driven gears.

    摘要翻译： 用于低地板车辆的驱动桥组件使用单个输入齿轮组件来驱动一对横向间隔开的轮端。 输入齿轮组件位于车轮端部之一旁边，使得可以降低车辆地板以便于乘客进入车辆。 每个车轮端部包括齿轮减速组件，其具有可旋转地安装在齿轮壳体内的齿圈。 驱动齿轮可操作地联接到输入齿轮组件并且与齿圈啮合。 齿轮减速组件还包括大于驱动齿轮的输出或从动齿轮，以提供所需的齿轮减速。 从动齿轮也与齿圈啮合。 一对空转齿轮可旋转地安装在齿轮箱内并与驱动齿轮和从动齿轮啮合。 空转齿轮和传动齿轮没有共同的中心线。 因此，该组件通过三个齿轮组合组合提供齿形接触，其均衡负载并且消除了用于驱动和从动齿轮的支撑轴承的需要。

    摘要： A wheel end assembly includes an output shaft that is directly mountable to a wheel adapter to drive a vehicle wheel. A gear assembly is coupled to the output shaft to transfer driving force from an input to the output shaft. The gear assembly includes an output gear that is directly coupled to the output shaft. Thus, the wheel adapter and output gear are both supported directly on the output shaft. The gear assembly and output shaft are substantially enclosed within a housing that is mounted to a non-rotating vehicle component. The output shaft is solely supported by a pair of bearings for rotation relative to the housing. The bearings are installed for direct engagement with the output shaft and housing.
