Abstract
A bi-directional overrunning clutch includes a housing and first and second hubs substantially coaxially aligned within the housing. A roll cage positions a plurality of rollers in an annular space between each of the hubs and an inner cam surface of the housing. The rollers are adapted to wedgingly engage between the hub and the inner cam for transmitting torque therebetween. End caps are attached to the housing adjacent to the hubs. A friction disk mechanism located on each side of the roll cage includes a roll cage plate attached to the roll cage, an inner hub friction member attached to the hub, a slip disk, and a spring compressed between the slip disk and the inner hub friction member biasing the inner hub friction member into frictional contact with the roll cage plate.
