Dual clutch transmission for a motor vehicle

A dual-clutch transmission for a motor vehicle, comprising:

• with gear wheel sets engageable via first to seventh shift elements, with the gear wheel sets forming precisely eight first to eighth wheel planes in series in the axial direction from the input side to the output side of the dual-clutch transmission, each wheel plane being allocated to a first sub-transmission and to a second sub-transmission, of which the first sub-transmission has an input shaft and the second sub-transmission has a second input shaft and both sub-transmissions have a common output shaft, wherein the input shafts, which are coaxial with respect to one another, can each be activated in an alternating manner via a power-shift clutch, and the even forward gears are allocated to the first sub-transmission and the odd forward gears are allocated to the second sub-transmission, which can be engaged upon a gear shift by way of the first to seventh shift elements, wherein each wheel plane provides a direct gear as a forward gear, with which, when the first or second sub-transmission is activated, precisely one wheel plane is engaged in the torque flow extending through the activated first or second sub-transmission, and wherein the wheel planes additionally provide at least one torsion gear as a forward gear, in which precisely three wheel planes, which are combined in series, are engaged in the torque flow by the first to seventh shift elements, wherein a total of four torsion forward gears, with a total of eight wheel planes, can be provided, and in that three wheel planes engaged for each torsion gear are allocated either completely to the first sub-transmission or completely to the second sub-transmission, so that, with each engaged torsion forward gear, only the sub-transmission having three wheel planes engaged for the respective torsion gear is integrated into the torque flow, and the other sub-transmission is completely de-coupled from the torque flow.
