Abstract: A work vehicle transmission has a disconnect device control assembly. The assembly includes a shaft having a rotation axis extending through a housing of the transmission. A disconnect device is mounted for co-rotation with the shaft about the rotation axis and has disengaged and engaged conditions. A gear is carried by the shaft to rotate about the rotation axis. The gear interacts with the disconnect device to rotate relative to the shaft in the disengaged condition and to co-rotate with the shaft in the engaged condition. A manifold is carried by the shaft and rotationally fixed relative to the rotation axis. The manifold defines a plurality of flow passages configured to route flow to the disconnect device. The manifold has an inner periphery that engages the shaft at a journal interface, which defines a flow passage for flow to pass from at least one of the flow passages of the manifold to the disconnect device.

Abstract: In accordance with an example embodiment, a transmission shifting apparatus may include a transmission having a plurality of gears and a clutch positioned between a power source and the transmission. A shift lever may operably connect to the transmission, such that movement of the shift lever causes the transmission to shift gears. A shift sensor may detect when the shift lever receives an operator input in a manner to generate a gear shift. A shift controller may selectively disengage the clutch when the shift sensor detects the operator input applied to the shift lever, and selectively engage the clutch when the shift controller determines the shift is complete.

Abstract: The present disclosure provides a gear shift assembly for shifting a transmission between a plurality of ranges. The assembly includes a user input adapted to be moved to induce a shift between two of the plurality of ranges and a shaft coupled to the user input. A movement of the user input induces a first movement of the shaft. The gear shift assembly also includes a first range member movably coupled to the shaft, where the first range member moves concomitantly with the shaft. A second range member is coupled to the shaft. The second range member also moves concomitantly with the shaft. The assembly further includes a control valve disposed in fluid communication with the second range member. The control valve is operably controlled in response to movement of the user input to direct fluid to the second range member to induce a second movement of the shaft.

Abstract: A concentric cylinder drive assembly (1) used for the transmission of power in industrial machinery is disclosed. More specifically, a concentric drive assembly (1) with a hollow outer cylinder (5) having an internal surface with a bi-directional surface lay; an inner cylinder (3) having an external surface with a unidirectional surface lay oriented at a predetermined angle (?) along the length of the cylinder; an annular channel established between the outer and inner cylinders having a predetermined gap (7); and a lubrication oil that substantially fills the annular channel is presented.
