Beschreibung
Zusammenfassung:	A shift gearbox may include at least two driven piston-cylinder units, which are each driven via a transmission of a drive, and the piston-cylinder units may each comprise a piston, which delimits a working chamber, and each working chamber is in hydraulic connection with at least one clutch actuator and at least one gear selector via a hydraulic main line, whereby the clutch actuator comprises a working chamber delimited by a piston. A valve may be respectively arranged between each working chamber of a clutch actuator and a hydraulic main line, and both the pressure build-up and the pressure reduction in the clutch actuators may occur by adjusting the piston of a piston-cylinder unit.
