Abstract
A clutch assembly comprises an actuation assembly, an outer ring, and an inner ring disposed radially inward of the outer ring and rotatable about an axis in first and second rotational directions. A first and second strut are rotatably disposed within first and second pockets of the outer ring and configured to be rotated by the actuation assembly. A first pawl and a second pawl are rotatably disposed within a third pocket and a fourth pocket, respectively. For a transition mode, the actuation assembly is configured to rotate the first strut within the first pocket such that rotation of the first strut in the first rotational direction urges the first pawl radially inward into partial engagement with teeth disposed on an outer surface of the inner ring, the second pawl remains free of contact with the inner ring and the inner ring rotates in the first rotational direction.
