Abstract: A clutch assembly is disclosed herein that generally has at least three operating conditions: an open condition, a transition condition, and a locked condition. The operating conditions are achieved based on displacement of a dog clutch ring relative to a pocket ring and a cam ring. In the open condition, rockers of a ratcheting assembly are completely disengaged from ramps on a cam ring. In the transition condition, the rockers engage with the ramps on the cam ring to allow a ratcheting motion in one rotational direction and a locked state in the other rotational direction. In the locked condition, splines on the dog clutch ring engage with splines on the cam ring to provide a rotationally fixed connection in both rotational directions.
