Title: Double clutch transmission

Abstract: A double clutch transmission with a double clutch, the input side of which can be driven and the output sides each communicate with one of two transmission input shafts that are arranged coaxially relative to one another, with an intermediate shaft and with fixed or idler gears that are mounted or rotatably supported on the shafts, and with shifting units that are allocated to the idler gears, with which the idler gears can be non-rotatably connected to the properly allocated shaft for the purpose of realizing gear ratio. To allow a more cost-effective production of this type of transmission, the fixed gears for the reverse gear and first gear are arranged axially directly in front each other on the same transmission input shaft, or that the fixed gears for the reverse gear and for the first gear are designed as a single common fixed gear.
