Coupling cover for fitting on engine flywheel

摘要

The pressure plate (3) has an annular projection (3b), which determines a first rotary point. A support plate (10) is supported inside the coupling cover (2) and formed with a ring-shaped extending area, which determines a second rotary point. A membrane spring (4) is supported within the coupling cover and tensions the pressure plate against the flywheel (50). The membrane spring is pivotable around the first and secondary rotary points. A conical spring (5) has an outer radial area in engagement with the membrane spring. It tensions the membrane spring away from the flywheel and has an inner radial area, which engages in the support plate. The coupling cover has several pin bolts (11), which run through a radial inner area of the coupling cover, the membrane spring and the support plate.
