Patent ID: 10626930

Abstract:
A wedge clutch, including: outer and inner races; a wedge plate radially between the inner and outer races; and an electromagnetic actuator. The electromagnetic actuator includes: a coil; a first coil core piece including a first end disposed within the coil and a second end connected to the wedge plate; and a second coil core piece including a first end disposed within the first coil and a second end connected to the wedge plate. In a locked mode of the clutch, the inner race and outer races and the wedge plate are non-rotatably connected for rotation of the inner race in a circumferential direction. In a free-wheel mode of the clutch, the inner race is rotatable, with respect to the outer race, in the circumferential direction. To transition from the locked mode to the free-wheel mode, the electromagnetic actuator is arranged to be energized to radially contract the wedge plate.
