Abstract
A clutch assembly includes an outer ring having a first and second pocket, and an inner ring. A strut and pawl may be disposed within the first and second pockets. The pawl may be configured such that rotation of the strut pushes the pawl toward teeth of the inner ring for engagement therewith. In a first mode of operation, the pawl does not contact the teeth and the inner ring is free to rotate in the first and second rotational directions. In a second mode of operation, the pawl is in partial engagement with the teeth and the inner ring is free to rotate in the second rotational direction and prevented from rotation in the first rotational direction. In a third mode of operation, the pawl is in full engagement with the teeth and the inner ring is prevented from rotation in both the first and the second rotational directions.
