摘要： A pulley assembly for an automobile accessory drive system includes a shaft engaging hub, a nut threaded onto the shaft engaging hub, an annular bushing, and one or more brake shoes positioned around the outside of the annular bushing all housed with a pulley member. The nut is capable of axial translation relative to the annular bushing and the annular bushing is capable of expanding radially outward in response to the axial translation of the nut in a first direction to provide frictional engagement between the inner coupling surface of the pulley member and the outer coupling surface of the brake shoes, which transfers torque from the pulley member to the input shaft. The nut includes a generally frustoconical outer surface, opposite its inner threaded surface, for seating the nut in the annular bushing.

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.

摘要： Zed-type belt tensioners are described that include an arm having a first end rotatable about a first axis to move a second end of the arm into engagement with a belt, a tensioner component coupled to the first end of the arm, and a supplemental force element positioned between the arm and the tensioner component. The second end of the arm while tensioning a belt experiences a hub load applied by the belt and the supplemental force element is positioned at a point to apply a force that counteracts the hub load thereby reducing cocking of the arm. Also described herein are methods of counteracting the hub load using such belt tensioners and methods of assembly of such belt tensioners.

摘要： A pulley assembly for use in an automobile accessory drive system (10) includes a shaft engaging member (40) including a bore (44) for receiving an accessory input shaft (78) for engagement therewith. A pulley member (50) includes a bore receiving an axially extending shaft (42) of the shaft engaging member (40). The pulley member (50) includes a first coupling surface (60) and a peripheral belt-engaging surface (52). A shaft extension member (64) transfers torque between the pulley member (50) and the shaft engaging member (40). The shaft extension member (64) includes a second coupling surface (62) facing the first coupling surface (60). The first and second coupling surfaces (60, 62) couple together when torque applied to the shaft extension member (64) is in a first direction such that the shaft extension member (64) and the shaft engaging member (40) rotate with the pulley member (50). The first and second coupling surfaces (60, 62) decouple when torque applied to the shaft extension member (64) is in a second direction opposite the first direction such that the shaft engaging member (40) rotates relative to the pulley member (50).

摘要： A first belt tensioner includes an arm (14, 112, 212), spring case (16, 114, 214), coil spring (12, 116, 216), and arm plate (118, 218). The arm (14, 112, 212) is adapted to support an idler pulley (20, 120, 220) and has a hook portion (22, 122, 222). The spring case (16, 114, 214) is disposed in the arm (14, 112, 212) and has a first spring seat (124). The spring (12, 116, 216) is disposed in the spring case (16, 114, 214). The arm plate (118, 218) has a second spring seat (132, 232). The spring (12, 116, 216) is longitudinally compressed between the arm plate (118, 218) and the spring case (16, 114, 214). The spring (12, 116, 216) is in torsion, with the end portions (18; 128, 130; 230) of the spring (12, 116, 216) seated against a corresponding spring seat (124, 132) and with the arm plate (118, 218) rotationally positioned under the hook portion (22, 122, 222). A method for assembling the first belt tensioner (110, 210) includes using the arm plate (118, 218) to longitudinally compress the spring (116, 216) and rotating the arm plate (118, 218). A second belt tensioner (10, 110, 210) includes an arm (14, 112, 212), spring case (16, 114, 214), coil spring (12, 116, 216), arm plate (118, 218), and pivot bushing (24, 148, 248).

摘要： A tensioner may be part of a power system to tension an endless power transmitting element. The tensioner includes an arm having an arm arbor with a slot therethrough that is rotatable about a first axis, a bushing having a sleeve that includes a cut-out and a removable sleeve-segment that has a protrusion thereon, the sleeve-segment being receivable in the cut-out with the protrusion in the slot, and a spring coupled to the arm for rotation of the arm about the first axis into tensioning engagement with a power transmitting element. The spring is positioned where it can radially expand into contact with the protrusion of the bushing, at least the protrusion on the sleeve-segment, as the arm is rotated in a direction opposite the direction of tensioning engagement such that the bushing is urged radially outward relative to the arm arbor to provide frictional damping.

摘要： A tensioner is disclosed that may be part of a power system where the tensioner provides tension to an endless power transmitting element such as a belt, chain, or other continuous loop. The tensioner has an arm that is rotatable about a first axis and includes an arm arbor having a slot therethrough, a bushing having a protrusion and being positioned adjacent the arm arbor with the protrusion received in the arm arbor's slot, and a spring coupled to the arm urging the arm to rotate about the first axis into tensioning engagement with a power transmitting element. The spring is positioned where it can radially expand into contact with the protrusion of the bushing as the arm is rotated in a direction opposite the direction of tensioning engagement such that the bushing is urged radially outward relative to the arm arbor to provide frictional damping.

摘要： A tensioner for an endless power transmitting element in a drive system is disclosed that includes an arm rotatable about an axis and having a sleeve that includes a ramp face or contoured face, a damper cup having a protrusion and a plate, a spring case that houses the sleeve of the arm and the damper cup with the damper cup's plate mated with the ramp face or contoured face of the sleeve. During wind-up of the tensioner, a normal force is applied to the damper cup's protrusion that moves the plate along the ramp face or contoured face in a first direction, and in the first direction the ramp face or contoured face pushes the damper cup generally radially outward into the spring case to provide frictional damping.
