A double clutch transmission with two clutches (K, K) having input sides connected to a drive shaft (w_an) and output side connected to one of two coaxially arranged transmission input shafts (w_k, w_k). At least two countershafts (w_v, w_v) are provided on which toothed idler gearwheels () are situated in a rotatable manner. Toothed idler gearwheels () are provided in a rotationally fixed manner on the two transmission input shafts (w_k, w_k). At least a plurality of forward gears which are power shiftable () and at least one reverse gear (R, R, R, R, R, R, R, R) are shiftable. A maximum of five gear planes (----) are provided so that at least one power shiftable winding path gear (G, G, R) is shiftable by at least one shift element (P).

Double clutch transmission

A double clutch transmission comprising two clutches each having an input side connected to a drive shaft and an output side connected to one of two transmission input shafts coaxially arranged with respect to one another. At least two countershafts, on which toothed idler gearwheels are pivotally supported and toothed fixed gearwheels are disposed on both transmission input shafts in a rotationally fixed manner and mesh with at least some of the idler gearwheels. A plurality of coupling devices connect an idler gearwheel to a countershaft in a rotationally fixed manner. One output gear is provided on both countershafts which is coupled to gearing of an output shaft. At least one first shift element connects two toothed gearwheels in a rotationally fixed manner such that a plurality of power shifting forward gears and at least one reverse gear can be shifted.

A double clutch transmission comprising two clutches, the input sides of which are connected to a drive shaft and the output sides of which are connected to one of two transmission input shafts coaxially arranged with respect to each other. At least two countershafts are provided on which toothed gearwheels, embodied as idler gearwheels, are supported. Toothed gearwheels, embodied as fixed gearwheels, are provided on both transmission input shafts in a rotationally fixed manner. At least one shift element is provided for connecting two toothed gearwheels in a rotationally fixed manner and at least a plurality of power shifting forward gears and/or at least one reverse gear may be shifted. Six gear planes are provided such that at least one power shifting winding path gear may be shifted via at least the shift element.
