Abstract
A one-way sprag clutch is disclosed. The clutch includes coaxial inner and outer races. A plurality of sprags arranged in a group is located within a cage between the races. The sprags are engageable with the inner surface and the outer surface by rotating in a first peripheral direction relative of the surfaces to transmit a torque between the two races. A plurality of bolts is located adjacent to the sprag group. The number of sprags in the group is greater than the number of bolts. In particular, one of the bolts limits rotation of the sprags in a first direction beyond an engaged position and a second bolt limits rotation of the sprags in a second direction to a lift-off position.
