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: The selectable clutch may include a first actuator and a second actuator. Moreover, the selectable clutch may further include a first cam operatively associated with the first actuator and a second cam operatively associated with the second actuator. Furthermore, a first armature may be actuated by the first actuator and a second armature may be actuated by the second actuator such that the selectable clutch is configured to allow multiple modes of operation provided by a movement of the first and second cams according to different first and second armature positions.

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 configured to engage the pawl clutch by engaging the notch of the first member. The notch of the first member may have one of a chamfered edge and a concave edge.

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.

Abstract: An actuation device having a piston is used to actuate a mechanical or friction clutch by means of differential pressure. Two sides of a piston are pressurized, and the relative pressure between the two sides is decreased or increased to move the piston in either direction. The position of the piston may be determined using position feedback, or with springs of known spring rates, two piston areas, and knowing the pressures of the two areas. The actuation device may be used with a selectable clutch to actuate an actuation cam, and may also have application with other clutches requiring the ability to achieve multiple positions and clutch modes.

Abstract: An actuator device for a selectable clutch having three or more clutch modes may include a dual rate piston with a stable middle position. A positive stop provides very accurate control when shifting from an end position to a middle position without overshoot. Precision position control of the actuator device facilitates consistent, stable control of the current mode of the selectable clutch.
