Abstract
A dual mode one-way torque transmitting device includes an inner race having a first plurality of notches spaced about an axis. An intermediate race includes a second plurality of notches spaced about the axis, a first plurality of pockets spaced about the axis, and a first plurality of rockers, each rocker being located in a pocket of the intermediate race. A spring urges each rocker toward engagement with a notch on the inner race. An outer race includes a second plurality of pockets spaced about the axis, a second plurality of rockers, each rocker being located in a pocket on the outer race, and a plurality of actuators, each actuator alternately engages and disengages a rocker on the outer race and a notch on the intermediate race.
