Abstract
A friction clutch selectively and directly couples a rotatable drive and driven members. The friction clutch includes first and second clutch members movable toward and away from each other along an axis between disengaged, partially engaged, and fully engaged positions. The first and second clutch members are independently coupled to the drive and driven members. The friction clutch further includes first and second friction materials positioned between the first and second clutch members. The first and second friction materials are each independently coupled to one of the first and second clutch members and are each independently engageable with an engagement surface of the other one of the first and second clutch members. The first friction material engages the respective engagement surface in the partially engaged position and the second friction material engages the respective engagement surface in the fully engaged position.
