In order to provide a reliable connection between a circular plate mounted on a hub and a friction material having a pair of oppositely faced friction surfaces extending in the axial direction in a clutch disc, a sub plate is secured to the circular plate. This permits the interposition therebetween of frictional material in such a manner that a plurality of axial openings are provided in the circular plate and the sub plate and the friction surfaces project from each opening in opposite axial direction.

Clutch disc having an integral annulus of friction material

An automotive vehicle clutch disc apparatus has a clutch hub provided with arm portions and an outer two-piece housing including, a clutch hub connected to a manual transmission, a stopper connected integrally with the clutch hub, a resilient element wrapping outward of the clutch hub, the stopper having a plurality of lugs, the housing having plurality of openings, the lugs are operatively connected to the opening and the clutch hub equipped with the resilient element applied to an initial deformation during assembly.

Clutch disk apparatus

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.
