Abstract:
A dual clutch transmission having countershafts, idler gears and input shafts with gears which engage with the idler gears. The countershafts have a power take-off gear that is coupled to an output shaft. Shift elements connect gear wheels to engage forward and reverse gears. The transmission has two dual gear planes and two single gear planes, one idler gear of the countershafts being respectively associated with a fixed gear of one of the transmission input shafts in each of the dual gear planes. An idler gear in each dual gear plane is utilized for two gears and one idler gear of one countershafts associating with an input shaft fixed gear to shift at least one winding path gear via at least one shift element on each countershaft, and at least one winding path gear can be shifted with a coupling device associated with the take-off gear of the first countershaft and is disengaged.
