Power take-off with remotely mounted clutch assembly and lubricated spline

摘要

A power take-off includes an input mechanism that is disposed within an input mechanism housing and is adapted to be connected to a source of rotational energy. A clutch assembly is disposed within a driveshaft housing and is adapted to be connected to a rotatably driven accessory. A driveshaft connects the input mechanism to the clutch assembly. The driveshaft may be disposed within the driveshaft housing, which also forms a housing for the clutch assembly.

主权项

1. A power take-off adapted to be used in conjunction with a vehicle drive train, the power take-off comprising:
an input mechanism housing including a hydraulic port assembly adapted to communicate with a source of pressurized fluid, a mounting surface adapted to be attached to a source of rotational energy, and an opening extending through the mounting surface; an input gear assembly rotatably supported within the input mechanism housing and having a portion that extends through the opening and is adapted to be rotatably driven by the source of rotational energy; a driveshaft housing having a first end that is secured to the input mechanism housing and a second end; a driveshaft rotatably driven by the input gear assembly and extending through the driveshaft housing to the second end thereof, the driveshaft including a passageway that communicates with the hydraulic port assembly; and a clutch assembly supported within the second end of the driveshaft housing and including an actuating mechanism that communicates with the passageway and an output member adapted to be connected to a rotatably driven accessory, wherein the actuating mechanism is responsive to pressurized fluid from the source of pressurized fluid for selectively connecting the driveshaft to the output member and thereby allowing the source of rotational energy to rotatably drive the rotatably driven accessory.
