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.

Abstract: A dual clutch assembly is operable to drivingly couple a first shaft with one or both of second and third shafts. The clutch assembly has a coil housing having a first electromagnetic coil and a second electromagnetic coil. The first shaft is rotatably mounted to the coil housing. The first shaft is fixed for rotation with a first rotor cooperating with the first electromagnetic coil and a second rotor cooperating with the second electromagnetic coil. A first armature plate is elastically coupled to the second shaft to selectively couple and uncouple the first shaft with the second shaft upon energizing and de-energizing the first electromagnetic coil. A second armature plate is elastically coupled to a third shaft to selectively couple and uncouple the first shaft with the third shaft upon energizing and de-energizing the second electromagnetic coil.
