Frictional overrunning clutch

A radially wedging, frictional overrunning sprag clutch has an inner ring defining an inner sprag track and an outer ring which is concentric with respect to the inner ring and defines an outer sprag track. While varying the ring thickness ratio of at least one of the two clutch rings in the sense of a maximum of the quotient driving torque/angle of rotation, the radius of the inner track is determined by subtracting from the nominal radius of the inner track the extent of compression of the inner ring, at the location of contact with the sprags, caused by an assumed normal force. The radius of the outer track is determined by adding to the nominal radius of the outer track the extent of expansion of the outer ring, at the location of contact with the sprags, caused by an assumed normal force.
