Abstract
An overrunning clutch is provided having inner and outer members disposed about a rotational axis with the outer member radially outward of the inner member. The clutch further includes a plurality of pins projecting from one of a radially inner surface of the outer member and a radially outer surface of the inner member. The clutch further includes one or more pawls coupled to one of the inner and outer members. Each of the pawls is movable between an engagement position wherein the pawl is engaged with one of the pins to transmit torque between the inner and outer members and a disengagement position wherein the pawl is disengaged from the pin to permit relative rotation of the inner and outer members. In one embodiment, different pawls assume their respective engagement position depending on the rotational direction of the one member.
