摘要

The friction clutch (1) has a clutch housing (4) with a rotationally fixed and axially displaceable pressure plate (5). The pressure plate is axially movable by a disk spring (6) against a counter thrust plate under tensioning by friction linings of a clutch disk for opening and closing the friction clutch. A bolt (20) is arranged between the disk spring and the clutch housing. A clearance (22) is adjusted between the bolt and the disk spring by a nut (21). The nut is secured against turning opposite to the bolt. Independent claims are also included for the following: (1) a method for calibration of a friction clutch; and (2) a forming tool for calibration of a friction clutch.
