Abstract
A three-mode clutch, including: an inner ring; an outer ring including a pocket; a cage radially disposed between the inner and outer rings, rotatable with respect to the outer ring, and including a ramp sloping radially inwardly; and a pawl including a portion disposed in the pocket. In a locked mode of the clutch, the ramp is in contact with the pawl and the inner and outer rings are non-rotatably connected. In a one-way mode of the clutch, the cage is in contact with the pawl and relative rotation of the inner ring with respect to the outer ring is enabled only in a first rotational direction. In a freewheel mode of the clutch, the ramp is in contact with the pawl and the inner ring is rotatable with respect to the outer ring in the first rotational direction and in a second rotational direction opposite the first rotational direction.
