Abstract
The invention relates to a clutch device with a pressure piston (1) for generating a pressure force for moving a clutch (4, 9, 8, 10, 27), in which the pressure piston (1) is guided to slide in a housing (5, 15.1) and the housing (5, 15.1) and the pressure piston (1) enclose a pressure chamber (11), which can be pressurized with a pressurizing agent (24) to generate the aforementioned pressure force and in which a balance piston (2) is present to generate a counterpressure force on the pressure piston (1), which is held essentially immobile to the housing (5, 15) when the clutch (4, 9, 8, 10, 27) is put into motion in the sliding direction of the pressure piston (1) and which, together with the housing (5, 15.1) and the pressure piston (1), encloses a balance chamber (12), which can be pressurized with a counterpressurizing agent to generate a counterpressure force. A latching mechanism (28.1, 29.1, 30.1, 31.1) is provided according to invention hold the balance piston (2) immobile as described above.
