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 drive unit assembly utilizes a single input to drive a pair of laterally spaced wheel ends. Each wheel end is suspended independently from the other. The input is operatively coupled to only one of the wheel ends and an exposed axle shaft assembly interconnects the input to the opposite wheel end. The axle shaft assembly includes multiple shaft members to interconnect the laterally spaced wheel ends. One of the axle shaft members is mounted to a vehicle floor structure with a bearing mount and includes connection joints at either end to accommodate the independent motion of each wheel end. The floor and the shaft member move together during suspension travel, allowing the floor to have a lower profile than is traditionally available.

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.

摘要： A suspension system includes a swing arm which pivots about a pivot axis. A hub assembly, hub gear box and input gear box are mounted to an independently pivoting swing arm. The pivot axis is located closer to the ground than a rotational axis defined by the hub assemblies and the input gear box. A coupling extends from the input gear box to receive an input driveline from a drive source such as vehicle engine. The coupling is located proximate the pivot axis to minimize relative movement during articulation of the swing arm. An axle housing extends between the input gear box and an opposite hub gear box to support a drive shaft and serves as a torsion bar.

摘要： An offset axle assembly includes a two-piece gear case. A first section of the gear case includes a drive gear assembly and the second section includes a driven gear attached to a shaft supported within the second section of the gear case. Attached to the end of the shaft is a hub. The hub is attached to the shaft by way of a plurality of mating splines. The hub is secured to the end of the shaft by a single nut. The hub may be removed from the shaft by removal of the single nut. One of the drive gear or driven gear assemblies is a planetary gear system. The planetary gear system includes a ring gear driven by a helical gear such that distance between axles is determined by the diameters of the helical and ring gear.

摘要： An axle system includes an axle lubrication level within an axle housing which is lower than a wheel end lubrication level within the wheel end assemblies. An opening through the wheel end assembly housing provides a fluid communication path between the wheel end assembly and the axle housing. A differential assembly rotates adjacent an opening such that lubrication at the wheel end lubrication level is rotated into the opening. The lubricant within the wheel end assemblies is maintained at the wheel end lubrication level. The shaft enters the wheel end assembly housing through a shaft opening which provides a communication path for the lubricant from the wheel end assembly back into the axle housing.

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.
