摘要： A bi-directional drive assembly for a work vehicle has a reaction member fixed with respect to or a part of a drive housing. A driveshaft is rotatable about a drive axis relative to the reaction member in a first rotation direction and alternatively in a second rotation direction. A planetary set is coupled to the drive shaft and configured to rotate an output hub in the first or second rotation direction. A clutch assembly is coupled to the reaction member and includes a first clutch and a second clutch. The first clutch is configured to interface the planetary set with the reaction member to effect a first rotation speed of the output hub in the first rotation direction and alternatively the second rotation direction. The second clutch is configured to interface the planetary set with the reaction member to effect a second rotation speed of the output hub in the first rotation direction and alternatively the second rotation direction. An actuator arrangement is configured to effect movement of the first clutch and the second clutch along the drive axis to selectively engage the planetary set.

摘要： A walking beam assembly includes a support beam and a mount member configured to mount the support beam on a vehicle chassis. Furthermore, the assembly includes a gear assembly that is supported proximate an end of the support beam. The gear assembly includes a gear train and a gear housing. The gear train is operably coupled to a wheel hub. The gear housing substantially encloses the gear train. Moreover, the walking beam assembly includes an input drive assembly with at least one movable part configured to deliver an input torque from the vehicle engine to the gear train. The input drive assembly includes an input drive housing that substantially encloses the at least one movable part. The input drive housing is attached to the gear housing such that an interior of the input drive housing is in fluid communication an interior of the gear housing.

摘要： An infinitely variable transmission (IVT) for a work vehicle includes a variator with a first transmission component configured to receive engine power from an engine, a second transmission component configured to receive IVP power from an IVP machine, and an output transmission component configured output summed engine power and IVP power. The IVT also includes a power reverser that connects the engine to the first transmission component of the variator and that transfers engine power to the first transmission component. The power reverser has a forward mode and a reverse mode. The power reverser, in the forward mode, is configured to rotate the first transmission component in a forward direction. The power reverser, in the reverse mode, is configured to rotate the first transmission component in a reverse direction.

摘要： A drive assembly includes a drive motor at least in part contained in a housing and having a rotor rotating an output shaft. A selector mechanism, at least in part contained in the housing, is movable into one of a plurality of orientations corresponding to one of a plurality of drive motor settings. An actuator, at least in part contained in the housing, is arranged to move the selector mechanism into one of the plurality of orientations. The actuator has first and second pistons each disposed in a piston chamber of the housing for movement by hydraulic pressure. The second piston is arranged in contact with the first piston and configured to aggregate and transfer forces from hydraulic movement of the first piston and the second piston to move the selector mechanism.

摘要： A vehicle walking beam assembly includes a support beam and a mount member configured to rotatably mount the support beam on the chassis. A gear assembly with a gear train and a gear housing is supported by the support beam. The gear train includes a gear with a first journal surface, and the housing includes a second journal surface. The walking beam assembly additionally includes an input drive assembly that delivers input torque from the engine to the gear train. Moreover, the walking beam assembly includes a reaction member connected to one of the gear housing and the gear of the gear train. The reaction member is configured to transfer a reaction force between the chassis and the one of the gear housing and the gear of the gear train as the first journal surface journals on the second journal surface.
