Abstract

A double clutch gearbox, which has a first volume flow valve for actuating a first clutch, which is arranged downstream, a second volume flow valve for actuating a second clutch which is arranged downstream, and a first hydraulic power source for supplying the volume flow valves and the clutches with a system pressure. In order to provide an improved double clutch gearbox, the clutches have fluid cooling which is arranged downstream of the first volume flow valve.
