  • System and method for actuating a mechanical diode clutch assembly
    Patent number: 9022194
    Abstract: The present disclosure provides an actuation assembly for applying a mechanical diode clutch. The clutch includes an outer member, an inner member, and a strut. The actuation assembly includes a plate having an apply portion and a plurality of legs, where each of the plurality of legs has a first end coupled to the apply portion and a second end adapted to couple to a shift sleeve. A mechanism is coupled to the apply portion of the plate. The mechanism includes at least one biasing member. The plate is moveable between an unapply position and an apply position such that a movement from the unapply position to the apply position induces contact between the mechanism and the strut.
