Abstract
A device for actuating a clutch, having an actuator with a pneumatic chamber (K) delimited by a pneumatic active area (A), two hydraulic chambers (K, K) each delimited by a hydraulic active area (A, A), and a control element (G) that is actively connected to the clutch and can be moved and subjected to a force by the active areas. The pneumatic active area is subjected to a pneumatic pressure by a compressed air source (Q) to generate force in an actuating direction (B). The hydraulic chambers can each be hydraulically connected to a storage container (Q) for hydraulic fluid by an electromagnetically actuatable 2/2-way proportional valve (V, V). Furthermore, a control system (CPU) is provided to independently control the pressure application of the pneumatic chamber and valve positions of the 2/2-way proportional valves.
