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).

Abstract: A pawl clutch is disclosed. The pawl clutch may comprise a first member having at least one notch, and a second member. The first member and the second member may be configured to rotate relative to each other at a speed differential when the pawl clutch is disengaged. The pawl clutch may further comprise at least one pawl moveably retained to the second member and having a toe portion configured to engage the pawl clutch by engaging the notch of the first member. The toe portion of the pawl may have a chamfered edge configured to contact a corner of the notch to reject engagement of the pawl with the notch when the speed differential is above a threshold.

Abstract: The selectable clutch module may include a first member and a second member positioned adjacent to the first member. The selectable clutch module may further include a plurality of notches formed on the second member and an actuator operably coupled to an armature. Furthermore, the selectable clutch module may include a selectable locking mechanism including a first pawl and a second pawl, wherein the first and second pawls are configured to interact with the plurality of notches such that the selectable locking mechanism is selectively controlled between a plurality of locking modes. The selectable clutch module may further include a cam operatively associated with the armature and the cam may include a cam profile configured to engage with the first and second pawls. Moreover, the actuator may positon the cam profile to selectably actuate the selectable locking mechanism into one of the plurality of locking modes.
