Abstract
A bi-directional wedge clutch, including: an outer race; first and second inner hubs; a wedge plate, radially located between the outer race and the inner hubs; and an axially displaceable activation hub engaged with the inner hubs and arranged to: for a free-wheel mode, rotate at least one of the inner hubs in a first rotational direction, with respect to the other of the inner hubs, such that the wedge plate is free of contact with the outer race; and for a locking mode, rotate the at least one of the inner hubs in a second rotational direction, opposite the first rotational direction, with respect to the other of the inner hubs, to non-rotatably connect the wedge plate with the outer race and the inner hubs.
