Abstract
A wedge clutch includes a hub supported for rotation about an axis and having an outer surface about a peripheral of the hub. The outer surface has a plurality of ramped surfaces. A carrier is also supported for rotation about the axis and has an inner surface. An inner surface of the disk is configured to slide along the ramped surfaces of the hub. The disk is moveable between an expanded position in which an outer surface of the disk engages the inner surface of the carrier to lock the clutch and a contracted position in which the clutch is unlocked. An armature is disposed in the disk and is configured to react to an electromagnetic force to alter the disk between the expanded position to the contracted position.
