Abstract
A two-way clutch biasing assembly including a two-way clutch having an inner race attached to an input shaft and an outer race attached to an output shaft. The inner and outer races having inner cammed portions between them, with an engagement assembly interposed therein that is adapted to rotate bi-directionally thereby providing selective mechanical engagement between the races in either direction. A planetary gear assembly is provided having a ring gear, planetary gears on a carrier, and a sun gear that is adapted to rotate the engagement assembly within the two-way clutch. A drag clutch assembly is also slidingly connected to the carrier to hold the carrier stationary when the input shaft is stationary, such that sun gear is rotated by the plurality of planetary gears, thereby rotating the engagement assembly within the two-way clutch and providing a mechanical advantage in engaging the races together when the input shaft begins to move.
