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 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: 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.
