  • Patent number: 4577740
    Abstract: A clutch cover assembly comprises a pre-assembled combination of parts including a cover (10) which is fixed in the axial direction and a pressure plate (14) which is movable in the axial direction. A diaphragm spring (11) acts on the pressure plate (14). There are means to limit axial movement of the axially movable part and to retain this part radially. These means comprise a limiting member (50) having at least one inclined surface (44) and a retaining member (47) having at least one edge (49) disposed opposite the aforementioned inclined surface and adapted to immobilize the axially movable part in the storage position of the pre-assembled combination. By virtue of mutual interference, sufficient cohesion is conferred on the assembly to protect its drive straps (23) from damage while in storage.

  • Patent number: 4562636
    Abstract: In a storage configuration of a clutch cover assembly, its pressure plate (14) is immobilized by at least one limiting member (41) comprising two lugs (43, 43') each having two arms (45, 46 (45', 46')). In the method of manufacturing the clutch cover assembly, the lugs (43, 43') are manufactured with a temporary shape (430, 430') and, during assembly, the pressure plate is positioned at an axial distance from the cover corresponding to the storage position. The lugs (43, 43') are then plastically deformed to their final shape.
