Abstract
An electromagnetic clutch includes an electromagnetic coil positioned within a coil housing. A pulley rotates relative to the housing and the coil. A shaft is rotatably supported by the housing. A hub plate is fixed for rotation with the shaft. A floating element is positioned between the pulley and the hub plate. An elastomeric ring is mounted between the pulley and the floating element and provides a driving connection therebetween. The elastomeric ring is sized to urge the floating element into frictional driving engagement with the hub plate and is compressible during energization of the coil to decouple the floating element from the hub plate.
