Abstract
A fully contained, drop-in clutch assembly, which includes a clutch cover which has slots, a moveable pressure plate with radially outwardly directed tabs that engages the slots of the clutch allowing axial movement, a fixed pressure plate which is fastened to the clutch cover by fastening elements, a clutch disc disposed between the movable pressure plate and the fixed pressure plate, and a diaphragm spring. By fastening the fixed pressure plate to the clutch cover, the clutch assembly is fully contained, allowing easy assembly to transmission housing and a flexplate.
Claims19
A clutch assembly for connecting a power producing device to a transmission, comprising:
- a clutch cover having slots;
- a moveable pressure plate having radially outwardly directed tabs engaging the slots of the clutch cover;
- a fixed pressure plate fastened to the clutch cover by fastening elements, ensuring the assembly is fully contained;
- a clutch disc disposed between the movable pressure plate and the fixed pressure plate;
- and
- a diaphragm spring arranged within the clutch cover.
A clutch assembly, which is normally open, for connecting a power producing device to a transmission, comprising:
- a clutch cover having slots;
- a moveable pressure plate having radially outwardly directed tabs engaging the slots of the clutch cover;
- a fixed pressure plate fastened to the clutch cover by fastening elements, ensuring the assembly is fully contained;
- a clutch disc disposed between the movable pressure plate and the fixed pressure plate;
- a diaphragm spring urging the moveable pressure plate away from the fixed pressure plate;
- and a first retaining member securing an outer circumferential edge of the diaphragm spring within the clutch cover.
A clutch assembly, which is normally closed, for connecting a power producing device to a transmission, comprising:
- a clutch cover having slots;
- a moveable pressure plate having radially outwardly directed tabs and radially inwardly directed tabs, the radially outwardly directed tabs engaging the slots of the clutch cover;
- a fixed pressure plate fastened to the clutch cover by fastening elements, ensuring the assembly is fully contained;
- a clutch disc disposed between the movable pressure plate and the fixed pressure plate;
- a diaphragm spring urging the moveable pressure plate towards the fixed pressure plate;
- a leaf spring having a radially outwardly directed tab movably fastened to the movable pressure plate by fastening elements, the radially outwardly directed tab of the leaf spring being engagable with one of the radially inwardly directed tabs of the moveable pressure plate forming a non-rigid connection to pull the moveable pressure plate away from the clutch discs;
- a first wire ring which is arranged between the moveable pressure plate and the diaphragm spring, and
- a second wire ring which is supported on the leaf spring, the diaphragm spring being pivotable on the second wire ring.
