Abstract
A combined power take-off and synchronizer assembly selectively connects a source of rotational energy to a driven accessory includes a power take-off portion that includes an input mechanism that is adapted to be rotatably driven by a source of rotational energy and an output mechanism that is rotatably driven by the input mechanism. The combined power take-off and synchronizer assembly also includes a synchronized clutch portion that selective connects the output mechanism of the power take-off portion to an output shaft that is adapted to be connected to a rotatably driven device.

A combined power take-off and synchronized clutch assembly that is adapted to be secured to a mounting surface provided on a source of rotational energy, the combined power take-off and synchronizer assembly comprising:
- (1) a power take-off portion including:
- (A) a housing having a mounting surface that is adapted to be secured to a mounting surface provided on a source of rotational energy, the mounting surface of the housing of the power take-off portion having an opening therethrough,
- (B) an input mechanism including an input gear that is rotatably supported on the housing of the power take-off portion and that has a portion that extends outwardly through the opening provided through the mounting surface of the housing of the power take-off portion and is adapted to extend within and be rotatably driven by the source of rotational energy, and
- (C) an output mechanism that is rotatably driven by the input mechanism;
- and
- (2) a synchronized clutch portion that selectively connects the output mechanism of the power take-off portion to an output shaft of the synchronized clutch portion that is adapted to be connected to a rotatably driven hydraulic pump that, in turn, operates a hydraulically driven accessory, wherein
- the output mechanism of the power take-off portion is rotatably journaled on the output shaft of the synchronized clutch portion,
