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： A vehicle information system has a first load sensor for generating a first load signal based on a first vehicle load. A first position sensor generates a first position signal based on a position of a vehicle axle. A second position sensor generates a second position signal based on a position of a vehicle kingpin. A memory unit stores vehicle optimization data. An evaluation unit is in communication with the first load sensor, the first position sensor, the second position sensor and the memory unit. A general user interface for receiving input is also in communication with the evaluation unit. The evaluation unit makes an evaluation of the first load signal, the first position sensor, the second position signal, and any input and generates a vehicle optimization instruction relating to a distance between the axle and the kingpin.

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： A mechanism is disclosed for controlling the vertical position of the transport trailer floor of a heavy trailer bearing vehicle having a pivoting air spring suspension system such that the transport trailer floor maintains a fixed position level to an adjacent dock platform when parked for loading or unloading. The mechanism comprises various embodiments of a locking system that disables the pivotal movement of selected pivoting suspension elements in any one of a plurality of possible fixed positions such that the transport trailer floor, when parked, resists downwardly imposed forces and maintains a fixed elevation equal to the elevation of an adjacent loading dock platform.

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 trailer suspension slider is provided that includes a suspension bogey. A trailer is supported on the suspension bogey and is longitudinally movable between a plurality of position relative to the suspension bogey. The trailer includes a stop bar to prevent the bogey from sliding out from underneath the trailer during braking if the pins are disengaged. A locking pin mechanism is movable between a locked position in which the locking mechanism couples the suspension bogey and the trailer in one of the plurality of positions and an unlocked position in which the trailer can move relative to the suspension bogey. The suspension bogey may collide violently with the stop bar when braking from a relatively low speed when the pins are unlocked. To this end, an energy absorption device is supported on either the trailer or the suspension bogey. The energy absorption device collapses in response to the stop bar engaging either the energy absorption device or the suspension bogey. Alternatively, an expandable cable may be used between the trailer and suspension bogey to slow the trailer as the stop bar approaches the suspension bogey.

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.
