Abstract
Pulley assemblies are disclosed that include a pulley body, a hub disposed within the bore of the pulley body, and a one-way clutch concentric about the hub. The one-way clutch has a plurality of cantilevered members that each include a friction surface and a cantilevered end and a biasing member in contact with one cantilevered member to bias the cantilevered members into continuous frictional engagement with the bore of the pulley body. Each of the cantilevered members is pivotable about its cantilevered end and is partially nested within an adjacent cantilevered member to form an annular body. This construction places the friction surface of each cantilevered member facing the bore of the pulley body. In operation, the pulley body rotates in a predominant direction which activates the plurality of cantilevered members to link the pulley body to the hub for simultaneous rotation.
