Abstract
A clutch assembly has a clutch cover secured to a flywheel, a diaphragm spring positioned outside the clutch cover, and an annular pressure plate positioned inside the clutch cover. The diaphragm spring is pivotally mounted on the clutch cover by rivets disposed in several openings formed in the diaphragm spring. The pressure plate is connected with the clutch cover by a suitable number of flexible drive straps which are disposed between the clutch cover and the pressure plate and extend chordally across the pressure plate. One end of each drive strap is secured to the pressure plate by a rivet. The other end of each drive strap is secured to the clutch cover by a rivet which is positioned radially inwardly of the inner periphery of the pressure plate and is aligned with an opening formed in the diaphragm spring. The rivet for securing each drive strap to the clutch cover may be riveted under the condition wherein one end of the drive strap is already secured to the pressure plate and the diaphragm spring is already secured to the cover plate.
