Friction clutch for double clutch device of transmission, has axially movable pressure plate actuated by relative rotation of ramps of ramp device, and actuating device with electromagnetically operated actuator for acting on ramp device

摘要

The clutch has an axially movable pressure plate (12) arranged opposite to an axially fixed pressing plate in a torque-proof manner. A clutch disk is axially deformed between the plates, and an actuating device (38) adjusts an axial distance between the plates to actuate the clutch. The pressure plate is actuated by relative rotation of ramps (34) of a ramp device (31), and the actuating device has an electromagnetically operated actuator (16) e.g. piezoelectric element, for acting on the ramp device, where the ramps are active between the pressure plate and a housing-fixed component (21).
