Structurally, the coil spring is arranged in concentric circles along the circumference of the pressure plate. The pressure plate, the release lever and the screw flag spring are all installed in the clutch cover to form the Clutch Cover Assembly. The flywheel serves as an active friction surface of the clutch, while the other active friction surface is the pressure plate. Third: the central spring clutch adopts a structural form in which 1 to 2 cylindrical spiral springs or a conical spiral spring with a rectangular section is arranged in the middle of the clutch.
