    摘要： A steering system for a vehicle is provided that includes a steering knuckle which is rotatable about an axis. The steering knuckle includes an upper attachment point and a lower attachment point. The attachment points define the steer axis. A rotational drive unit is connected to the steering knuckle for rotating the steering knuckle about the steer axis. A control module receives a steering input corresponding to the desired Ackerman angle and commands the rotational drive unit to rotate the steering knuckle about the axis to the desired Ackerman angle. Rotational drive units for each side of the vehicle ensure that the wheels are turned to the appropriate Ackerman angle for each wheel. The rotational drive unit may include an electric motor, or a pneumatic or hydraulic pump. In one preferred embodiment, the rotational drive unit includes a fluid housing and the shaft connected to the steering knuckle. The shaft includes a vane extending therefrom and into the housing. The fluid pump pumps fluid into the housing to rotate the vane with the shaft and steering knuckle about the axis in response to a command from the control module.

    摘要： A wheel end assembly 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, intermediate gears in meshing engagement with the input gear, and an output gear in meshing engagement with the intermediate gears. A tube has one end press-fit into the gear housing with an opposite end extending into a wheel hub cavity. Bearings are mounted directly between the tube and the wheel hub to support the wheel hub for rotation relative to the tube. The output shaft is received within the tube with an inboard end in direct driving engagement with the output gear and with an outboard end directly mounted to the wheel hub.

    摘要： A steering system is provided for a vehicle including a frame. Upper and lower control arms have first end portions that are pivotally supported on the frame at first spaced apart connections. The control arms also each include second end portions that are pivotally connected to an intermediate support member at second spaced apart connections. A steer knuckle is pivotally supported by the intermediate support member at third spaced apart connections that define a king pin axis. A drive motor is mounted on the intermediate support member and is coupled to the steering knuckle to rotate the steering knuckle about the king pin axis relative to the intermediate support member. A gear set may also be used in conjunction with the drive motor and steering knuckle. The intermediate support member is constrained against forward and aft movement, but is permitted to move upward and downward with the control arms.

    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： A compound gear assembly includes two gears, each gear respectively including interlocking features, which may be complimentary arcuate sections, for transferring torque between the gears. A clearance between the respective arcuate sections permits the gears to move radially relative to one another, which ensures that the gears mesh in a desired manner with the gears to which they are coupled. A retainer is inserted into an annular groove located circumferentially about the respective arcuate sections, which secures one gear to another.

    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。
