イプクラツチカバーアツセンブリ。[Claims for Utility Model Registration] (1) A diaphragm spring having an enlarged opening at the radially outer end of a radial slit,
The outer fulcrum part of the diaphragm spring is supported by the clutch cover, the intermediate fulcrum part is in contact with the fulcrum land of the pressure plate, the inner fulcrum part is supported by the release bearing, and the release bearing is opposite to the pressure plate. In the pull type clutch, which disconnects the clutch by moving the clutch axially rearward, grooves are provided at multiple locations spaced apart in the circumferential direction of the Fulcrum land, and a disc-shaped cone spring is attached to the pressure plate. and the diaphragm spring, and provided on the outer periphery of the cone spring and facing outward in the radial direction.
A second protruding piece provided at the tip of the protruding piece is fitted into the groove, and the tip of the first protruding piece is brought into contact with the fulcrum land from the diaphragm spring side, and the clutch rotation direction side of the first protruding piece is brought into contact with the Fulcrum land. A third protruding piece provided on the side edge of the diaphragm spring that protrudes toward the diaphragm spring side and whose tip is bent in the direction of clutch rotation is passed through the enlarged opening with a gap in the clutch rotation direction. A pull type clutch cover assembly, characterized in that it is provided so as to come into contact with a diaphragm spring. (2) The outer supporting point of the diaphragm spring is supported by the clutch cover, the intermediate supporting point is in contact with the fulcrum land of the pressure plate, the inner supporting point is supported by the release bearing, and the release bearing is supported by the pressure plate. In a pull-type clutch that disconnects the clutch by moving the clutch axially rearward on the opposite side, a disc-shaped cone spring is arranged between the diaphragm spring and the clutch cover, and the outer periphery of the cone spring is connected to the diaphragm spring. A pull-type clutch cover assembly, characterized in that it abuts against the inner surface of the clutch cover from the opposite side, and is provided so that its inner peripheral edge moves integrally with the diaphragm spring toward the pressure plate in the axial direction.
