Friction clutch device e.g. single friction clutch device for powertrain of internal combustion engine driven motor car, has spring device with plate or lever spring that is engaged with actuator in radial plane

摘要

The friction clutch device (104) has an actuator (110) that is axially displaced with a pressure plate for actuating pressure plate by the force of a spring device. A plate or lever spring of the spring device is engaged with the actuator in a radial plane. The actuator is provided with a linear piezoelectric actuator portion. The actuator at the plate or lever spring is engaged with a transmission element.
