ABSTRACT:
A friction clutch is provided that includes a clutch cover, an intermediate plate that is spaced apart from an engine flywheel, a first friction disk positioned between the flywheel and the intermediate plate, a pressure plate spaced apart from the intermediate plate and a second friction disk positioned between the intermediate plate and the pressure plate. The clutch further includes a first drive strap for applying a load to the intermediate plate, a second drive strap for applying a load to the pressure plate and a separator arm attached to the intermediate plate. The separator arm engages the second drive strap such that axial movement of the intermediate plate relative to the clutch cover is a fraction of the corresponding axial movement of the pressure plate during engagement and disengagement of the clutch.
