Zusammenfassung:	A pulley assembly for use in an automobile accessory drive system includes a shaft engaging hub, a pulley member, a nut treaded onto the shaft engaging hub, and a brake member interposed between the pulley member and the nut. The shaft engaging hub is engaged with an accessory input shaft for rotation therewith. Frictional engagement between the pulley member, the brake member, and the nut transfers torque from the pulley member to the input shaft. The pulley member includes an inner coupling surface and a peripheral belt- engaging surface. The nut includes an outer coupling surface. The brake member includes a first coupling surface in frictional engagement the outer coupling surface of the nut and a second coupling surface in frictional engagement with the inner coupling surface of the pulley member.
