The invention relates to a double clutch transmission of a motor vehicle, comprising two input shafts (3, 4), which are disposed coaxially to each other and can be connected to the drive shaft (2) of a driving motor via a separate clutch (K1, K2). The invention further comprises two countershafts (11, 12), which are arranged parallel to the axis next to the input shafts (3, 4) and are connected and driven via a driven wheel (8, 9) by a common output element (10). The invention further comprises a plurality of gear wheel sets, comprising a plurality of toothed wheels, amongst others one fixed wheel and one loose wheel, wherein at least two wheels are in engagement with each other. The fixed wheels thereof are distributed on the two input shafts (3, 4) and are arranged rotationally fixed on the associated input shaft (3, 4). The loose wheels are distributed on the two countershafts (11, 12), are rotationally arranged on the associated countershaft (11, 12) and can be connected thereto in a rotationally fixed manner by an associated clutch. Each of the two input shafts (3, 4) comprises at least one fixed wheel, which is associated with two gear wheel sets and engages with loose wheels arranged on different countershafts (11, 12). A double clutch transmission of this type, having six forward gears (G1 to G6) and one reverse gear (R), is proposed as a basic transmission, which has an uncomplicated and space-saving design and can be reduced by one gear to form a five speed transmission and be expanded by one gear to form a seven speed transmission in a simple and cost-effective manner. |
