    摘要： A wheel end assembly for a mass transit vehicle includes an output shaft mounted to a wheel hub for driving a vehicle wheel. The output shaft is driven by a gear assembly mounted within a gear housing and operably coupled to an input shaft. The gear assembly includes an input gear driven by the input shaft, a first reduction gear in meshing engagement with the input gear, a second reduction gear operably coupled to the first reduction gear for rotation therewith, and an output gear in meshing engagement with the second reduction gear. The first and second reduction gears are supported on a common shaft that is positioned between the input and output shafts. The input gear and first reduction gear are positioned outboard from the output gear and associated bearings. This double reduction configuration allows vehicle aisle width to be maintained while providing a deeper drop allowing the vehicle floor to be lowered to a position closer to the ground.

    摘要翻译： 用于公共交通车辆的车轮端组件包括安装到用于驱动车轮的轮毂的输出轴。 输出轴由安装在齿轮壳体内的齿轮组件驱动并且可操作地联接到输入轴。 齿轮组件包括由输入轴驱动的输入齿轮，与输入齿轮啮合的第一减速齿轮，可操作地联接到第一减速齿轮以与其一起旋转的第二减速齿轮，以及与第二减速齿轮啮合的输出齿轮 减速器。 第一和第二减速齿轮支撑在位于输入轴和输出轴之间的公共轴上。 输入齿轮和第一减速齿轮位于输出齿轮和相关轴承外侧。 这种双重减速配置允许保持车辆通道宽度，同时提供更深的下落，允许车辆地板降低到靠近地面的位置。
