Title:
非対称的なトルク感受性クラッチ作用を示すベルト車
Document Type and Number:
Japanese Patent JP2013520633
Kind Code:
A
Abstract:
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. When torque is applied to the nut in a first direction the out coupling surface of the nut couples to the inner coupling surface of the brake member such that the hub and the nut rotate with the pulley member. The outer coupling surface of the nut and the inner coupling surface of the brake member decouple when torque applied to the nut is in a second direction opposite the first direction such that the hub rotates relative to the pulley member.
