ABSTRACT:
A pulley assembly for use in an automobile accessory drive system includes a shaft engaging member including a bore for receiving an accessory input shaft for engagement therewith. A pulley member includes a bore receiving an axially extending shaft of the shaft engaging member. The pulley member includes a first coupling surface and a peripheral belt-engaging surface. A shaft extension member transfers torque between the pulley member and the shaft engaging member. The shaft extension member includes a second coupling surface facing the first coupling surface. The first and second coupling surfaces couple together when torque applied to the shaft extension member is in a first direction such that the shaft extension member and the shaft engaging member rotate with the pulley member. The first and second coupling surfaces decouple when torque applied to the shaft extension member is in a second direction opposite the first direction such that the shaft engaging member rotates relative to the pulley member.
