Abstract: An overrunning clutch assembly comprises a housing and a tubular shaft rotatably coupled together with a roller or sprag clutch positioned therebetween to permit the housing to freely rotate about the shaft in one direction, or to establish torque communication between the shaft and the housing when rotated in the opposite direction. To minimize the weight of the assembly while also containing the radial forces and stresses generated by the roller clutch when transmitting torque, the housing and the shaft are reinforced with high-strength, high-modulus materials having high strength-to-weight ratios.
