Abstract
A clutch (10) for selectively preventing rotatory movement of a cogged gear (12) about an axis may include an actuator (20) and a pivotally moveable pawl (40) that is interactive with the cogged gear (12). A plunger (24) may be radially movable within and by the actuator (20). A pair of axially spaced sidewalls (16, 18) may include an opposed radially extending slot (52). A pawl pusher (50) may be radially movable between the plunger (24) and the pawl (40). The pawl pusher (50) may include a pair of axially extending wing portions (54, 56) that may be slidably supported in one of the opposed slots (52) to limit movement of the pawl pusher (50) to radial, only. Axial and/or circumferential force loads transmitted to the pawl pusher (50) by the pawl (40) may not be transferred to the radially movable plunger (24).
