Abstract
A one-way or selectable clutch with multiple circumferential rows of ratchet elements is disclosed. The clutch may include two or more rows of ratchet elements extending between two or more races. The device may be either a one-way clutch or a selectable mechanical clutch, and afford the benefits of reduced backlash and multiple modes of operation. Those modes may include free-wheel/overrun in both clockwise and counterclockwise directions, locked/transmit torque in both directions, locked in clockwise and overrun in counterclockwise directions, and locked in counterclockwise and overrun in clockwise directions.
