Abstract:
A clutch assembly including a cover and a mounting ring having a plurality of arms extending outwardly to a strap mount. The assembly includes strap springs. Each strap spring has a first end connected to the strap mount and a second end opposite the first. The clutch assembly includes an annular pressure plate and a plurality of outwardly extending tabs. Each tab is releasably connected to the second end of a corresponding strap spring so the strap springs biases the pressure plate away from the flywheel. The assembly includes a keeper and a resilient diaphragm spring that biases the pressure plate toward the flywheel, deforming each strap spring, so the strap spring biases the annular pressure plate away from the flywheel. The diaphragm ring is resiliently deformable to a deformed position, allowing each strap spring to move the pressure plate away from the flywheel.

Claim (Index 16):
A clutch assembly, comprising:\n a bowl-shaped cover having a concave face and an outer flange surrounding the concave face and a central axis; a mounting ring releasably connected to the concave face of the cover, said mounting ring including a fulcrum ridge centered about the central axis and a plurality of arms extending outwardly to a strap mount; a keeper releasably connected to the mounting ring, said keeper including a release fulcrum centered about the central axis opposing the fulcrum ridge of the mounting ring at a predetermined distance; a resilient diaphragm spring captured between the fulcrum ridge of the mounting ring and the release fulcrum of the keeper, said diaphragm spring having an annular spring body and a plurality of levers, each lever of said plurality of levers extending inwardly from the spring body to an inner end; a plurality of primary strap springs, each strap spring of said plurality of primary strap springs having a first end releasably connected to the strap mount of a corresponding arm of said plurality of arms and a second end opposite the first end; a primary annular pressure plate having a plurality of outwardly extending tabs, each tab of said plurality of tabs being releasably connected to the second end of a corresponding strap spring of said plurality of primary strap springs; a plurality of secondary strap springs, each strap spring of said plurality of secondary strap springs having a first end releasably connected to the first end of a corresponding strap spring of said plurality of primary strap springs and a second end opposite the first end; and a secondary annular pressure plate having a plurality of outwardly extending tabs, each tab of said plurality of tabs of said secondary annular pressure plate being releasably connected to the second end of a corresponding strap spring of said plurality of secondary strap springs; a flywheel releasably connected to the outer flange of the cover; a first friction disc positioned between said primary pressure plate and said secondary pressure plate, said primary friction disc including a first friction surface surrounding a central hub facing the primary pressure plate and a second friction surface opposite the first friction surface of the first friction disc facing the secondary pressure plate, said primary pressure plate engaging the first friction surface of the first friction disc when axially moved to a first engaged position and the second friction surface of the first friction disc engaging the secondary pressure plate when axially moved past the first engaged position to a secondary engaged position; and a second friction disc positioned between said secondary pressure plate and the flywheel, said second friction disc including a first friction surface surrounding a central hub facing the secondary pressure plate and a second friction surface opposite the first friction surface of the second friction disc facing the flywheel, said secondary pressure plate engaging the first friction surface of the second friction disc when axially moved to a third engaged position and said second friction surface of said second friction disc engaging the flywheel when axially moving to a fourth engaged position, in which contacting interfaces between the pressure plate and the first friction disc, between the first friction disc and the secondary pressure plate, between the secondary pressure plate and the second friction disc, and between the second friction disc and the flywheel are capable of transmitting torque between the cover and the central hubs of the primary and second friction discs.
