    摘要: A power train and related vehicle are described for continuously variable transmission of power. A gear set includes first and second input components and an output component. An engine provides mechanical power to the first input component and, when a clutch device is in a first state, to a first continuously variable power source (“CVP”). With the clutch device in a second state, the first CVP is decoupled from the engine. A second CVP receives non-mechanical power from the first CVP, and converts the non-mechanical power to mechanical power. When a brake device is not engaged, the second CVP provides the resulting mechanical power to the second input component. When the brake device is engaged, the brake device prevents the second input component from rotating.

    摘要: A work vehicle includes an engine and a transmission assembly having a variator, a gear arrangement, and an electric machine operably connected to the engine and to the variator to provide rotational power to the variator. The transmission assembly selectively transfers power from one or both of the engine and the electric machine to an output shaft to drive ground engaging elements of the work vehicle. A traction control unit controls a speed or torque output of the electric machine to provide traction control for the work vehicle, with the traction control unit operating to receive inputs on a commanded ground speed and an actual ground speed of the work vehicle, compare the commanded ground speed to the actual ground speed and, when the commanded ground speed exceeds the actual ground speed by a threshold amount, reduce the speed or torque output of the electric machine, thereby providing traction control for the ground engaging elements.

    摘要: A drive arrangement includes a housing having two chambers and a partition defining an annular space within the housing. A disk is mounted on a shaft of the drive arrangement and includes an annular portion disposed within the annular space. A face of the annular portion is axially spaced from the partition by a gap clearance. An axial dimension of the gap clearance is such that rotation of the disk generates a negative pressure gradient for drawing fluid from the first chamber through the gap clearance in a radial direction toward the rotation axis. The fluid then moves along the face of the disk in a radial direction away from the rotation axis under centrifugal action of the rotating disk. The outer periphery of the disk is spaced from the housing to permit fluid to pass, by centrifugal action, from the outer periphery toward a second chamber.
