Abstract: An overrunning coupling assembly and a method of controlling the engagement of planar first and second members are provided wherein the assembly includes clustered pawls and their respective pawl-holding portions. The planar first and second members have inside surfaces extending generally normal to a first axis. The pawls include a forward set of free-floating pawls and a reverse set of free-floating, clustered pawls. The forward and reverse sets of pawls are movable between a notch-engaging, engaged position and a disengaged position. Because of the clustering, a control element, disposed between the first and second surfaces, need not be fully circular and is controllably rotatable about the first axis between first and second angular positions relative to the first member.

Abstract: An overrunning clutch (24) has first and second clutch members (30, 32) having coupling faces (34) and (36) between which spring biased pivotal struts (40) and locking formations (44) cooperate to prevent relative rotation in only one direction. A snap ring (48) and thrust plate (50) cooperate to axially secure the clutch members (30) and (32) to each other and the thrust plate has a retainer (52) projecting therefrom to prevent rotation. The retainer (52) in certain embodiments is received between ends (58) of the snap ring (48) to prevent thrust plate rotation.
