Abstract
A cylindrical bi-directional wedge clutch, including: an axis of rotation; a carrier ring; a wedge plate including at least a portion disposed radially inwardly of the carrier ring; and a tapered hub disposed radially inwardly of the carrier ring, displaceable, for first and second locked modes in which the hub and the carrier ring are non-rotatably connected, in a first axial direction to contact the wedge plate and expand the wedge plate radially outwardly, and displaceable, for a free-wheel mode in which the tapered hub and the carrier ring are rotatable with respect to each other, in a second axial direction, opposite the first axial direction. For the first locked mode, the tapered hub and carrier rotate in a first circumferential direction. For the second locked mode, the tapered hub and carrier ring rotate in a second circumferential direction, opposite the first circumferential direction.
