Abstract
A positive locking overrunning clutch mechanism comprising an inner clutch member, an outer clutch member, and a locking mechanism. The clutch members are adapted to rotate about a clutch axis. The locking mechanism has a plurality of lock portions adapted to transfer torque load from the inner clutch member to the outer clutch member. The locking mechanism is moveable between a locked position and an unlocked position. In the locked position, the lock portions simultaneously engage the inner and outer clutch members in a manner to cause the outer clutch member to rotate with the inner clutch member upon rotation of the inner clutch member about the clutch axis in a first rotational direction. In the unlocked position, the lock portions are positioned relative to the inner and outer clutch members in a manner to permit rotation of the outer clutch member relative to the inner clutch member in the first rotational direction. Each lock portion is a first radial distance from the clutch axis when the locking mechanism is in the locked position and a second radial distance from the clutch axis when the locking mechanism is in the unlocked position. One of the inner and outer clutch mem…
