Abstract:
A twin-clutch for attachment to a flywheel of an engine, comprising:a clutch disk assembly having a first frictional coupling portion configured to be disposed adjacent the flywheel, and a second frictional coupling portion disposed axially remote from said first frictional coupling portion;an annular intermediate plate disposed between said first and second frictional coupling portions, said intermediate plate being formed with a first recess on a radially outer portion thereof;a clutch cover assembly including a clutch cover configured for attachment to said flywheel, a pressure plate disposed within said clutch cover adjacent to said second frictional coupling portion, said pressure plate being formed with a second recess on a radially outer portion thereof, said second recess being axially aligned with said first recess and said second recess being open toward said first recess, said second recess having a rivet inserted therein concentric therewith, and a diaphragm spring supported on said clutch cover biasing said pressure plate toward the flywheel with said first frictional coupling portion, said annular intermediate plate and said second fictional coupling portion disposed in order between the flywheel and said pressure plate;a first elastic member connected to the flywheel and connected to said intermediate plate, and biasing said intermediate plate away from the flywheel in a clutch engagement state;a second elastic member arranged in a compressed state between said pressure plate and said intermediate plate, said second elastic member being a coil spring and having substantially the same spring constant as said first elastic member, said send elastic member extending into said first recess and also extending into said second recess, said second elastic member being retained in said second recess in said pressure plate by said rivet; anda third elastic member connected to said pressure plate and connected to said clutch cover limiting axial movement therebetween.
