Friction clutch for shift transmission of motor vehicle, comprises clutch housing and pressure plate, which is axially displaceable opposite to clutch housing by cup spring, where ramp ring is arranged between cup spring and pressure plate

摘要

The friction clutch (1) comprises a clutch housing (3) and a pressure plate (4), which is axially displaceable opposite to the clutch housing by a cup spring (6). A ramp ring (8) is arranged between the cup spring and the pressure plate forming a ramp device with the pressure plate. The ramp device changes the axial distance of a contact area between the pressure plate and the cup spring with the rotation of the ramp ring in the circumferential direction relative to the pressure plate. A pinion (12) is provided in engagement with a driving pawl (13), which is fixed to the pressure plate.
