Locking disconnect clutch

A power transfer unit comprising:

• a disconnect clutch comprising:
• a hub comprising a radially outer surface with a ramp and a first radial slot;
• a carrier comprising a radially inner surface;
• a cam plate, rotationally displaceable relative to the hub and including a second slot with a radius that varies in a circumferential direction;
• at least one wedge plate disposed radially between the hub and the carrier, comprising:
• a radially inner surface with a ramp, near and complementary to the hub outer surface;
• a radially outer surface near the carrier inner surface;
• a split extending from the radially inner surface to the radially outer surface;
• and,
• a third radial slot;
• at least one friction plate drivingly connected to the carrier;
• a pressure plate arranged for frictionally engaging the at least one wedge plate with the at least one friction plate;
• a pin disposed in the first radial slot and including an axial protrusion disposed in the second slot, the pin being:
• arranged to radially engage the third radial slot;
• rotationally fixed and radially displaceable with respect to the hub;
• arranged for limiting rotation of the at least one wedge plate relative to the hub;
• and,
• arranged to be radially displaced when the cam plate rotates relative to the hub;
• a housing;
• a first piston disposed in the housing and arranged for axially displacing the pressure plate;
• and,
• a clamping plate, rotationally fixed relative the housing and arranged for frictional engagement with the cam plate.
