Abstract
A dual disc clutch system having a flywheel, at least one spacer ring, first and second clutch discs, the second clutch disc being spring-modified, a floater ring, and a pressure plate having a diaphragm spring which engages clamps the first and said second clutch discs against the flywheel. The system can be used to convert single disc clutch systems into dual disc clutch systems.
Claims9
A dual disc clutch system, comprising:
- a flywheel having an engagement surface and a peripheral wall axially extending from said engagement surface;
- at least one spacer ring, said at least one spacer ring having a radially outer surface and a radially inner surface, said radially outer surface having no formations or projections;
- a first clutch disc, said first clutch disc not being spring-modified;
- a floater ring;
- a second clutch disc, said second clutch disc being spring-modified;
- a pressure plate having a diaphragm spring, said pressure plate releasably clamping said first clutch disc and said second clutch disc against said flywheel;
- and
- said peripheral wall being of a height sufficient to encompass at least one spacer ring, said first clutch disc, said floater ring, and said second clutch disc.

A dual disc clutch system, comprising:
- a flywheel having an engagement surface and a peripheral wall axially extending from said engagement surface;
- at least one spacer ring mounted within said peripheral wall, said at least one spacer ring having a radially outer surface and a radially inner surface, said radially outer surface having no formations or projections, said at least one spacer ring having at least one receiving formation along said radially inner surface;
- a first clutch disc mounted within said peripheral wall;
- a floater ring mounted within said peripheral wall, said floater ring having at least one projecting formation thereon, said projecting formation releasably fitting within said receiving formation;
- a second clutch disc mounted within said peripheral wall, said second clutch disc being spring-modified;
- and
- a pressure plate having a diaphragm spring, said pressure plate releasably clamping said first clutch disc, said floater disc, and said second clutch disc against said flywheel, whereby said clamping by said pressure plate moves said projecting formation into engagement with said receiving formation, releasing of said clamp by said pressure plate causes said projecting formation to come out of engagement with said receiving formation.
