NON-FRICTION COUPLING AND CONTROL ASSEMBLY, ENGAGEABLE COUPLING ASSEMBLY AND LOCKING MEMBER FOR USE IN THE ASSEMBLIES

摘要

An overrunning, non-friction coupling and control assembly, an engageable coupling assembly and locking members for use in the assemblies are provided. A centroid or center of mass of at least one of the locking members is offset from a pivot axis of the locking member so that as the locking member moves from an engaged position, a moment arm of the centroid relative to the pivot axis decreases from a maximum value to substantially zero in a disengaged position to facilitate disengagement of the locking member at high rotational speeds.
