Abstract
The invention is based on a device for actuating a clutch ( ), in particular for motor-vehicle drives, having an electronically controllable clutch servo unit ( ) that comprises an electric motor ( ) and a reduction actuator gear ( ) having two gear elements arranged coaxially in relation to each other ( and/or and/or ) that are interconnected with each other in terms of propulsion via a thread ( ) and that are displaced axially in relation to each other when they rotate relative to one another, whereby one of the gear elements ( ) is immobilized axially in a housing ( ) of the clutch servo unit, and the actuating motion of the other gear element ( ) is transferred to a throwout bearing ( ) of a clutch disk. It is proposed that the gear element ( ) that is axially displaceable relative to the housing ( ) is interconnected via a longitudinal guide ( ) with a rotor ( ) or a motor shaft ( ) of the electric motor ( ) in a fashion that is torsion-resistant but axially displaceable, and acts on the throwout bearing ( ) via an actuator ( ).
