ABSTRACT:
An overrunning clutch is disclosed wherein drive and driven clutch members are engaged by means of sprags which frictionally engage the clutch members in a locking position but which permit relative rotation of the clutch members in a freewheel position. The sprags are part of a sprag assembly including a pair of spaced cages, one frictionally biased to one clutch member and the other frictionally biased to ground. The sprags are symmetrical and provide for double-acting, direction-sensitive operation.
