Friction clutch for transmitting high torque between e.g. internal combustion engine and transmission in commercial vehicle, has kinematic chain decoupled between ramp ring and driving pawl during assembling friction clutch

摘要

The friction clutch (1) has a flywheel provided with a counter-pressure plate. A pressure plate (6) is axially moved by a disk spring (7). A wearout condition of the pressure plate is detected by relative movement between a driving pawl (12) and a pinion gear (10) that is arranged coaxial to a spindle (11) of a spindle drive (9), where the pawl is arranged at a housing side. The pinion gear is rotationally driven by the driving pawl during the wearout condition. A kinematic chain between a ramp ring (8) and the driving pawl is decoupled during assembling the friction clutch.
