The invention relates to a dual clutch transmission for a motor vehicle, having gear wheel sets which are shiftable via shifting elements and which in particular form exactly eight wheel planes (RE-1 to RE-8), each of which are allocated to a first sub-transmission (A) and to a second sub-transmission (B), of which each sub-transmission (A, B) has an input shaft (22, 23) and both sub-transmissions (A, B) have a common driven shaft (24), wherein the input shafts (22, 23), which are coaxial to each other, can each be activated in alternation via a load-shiftable clutch (K1, K2) and the even forward gears are allocated to the first sub-transmission (A) and the odd forward gears are allocated to the second sub-transmission (B), which are shiftable via the shifting element (SE-A to SE-G) during a gear shift, wherein at least two wheel planes (RE-1, RE-2) of one of the sub-transmissions (A, B) have drive-side gear wheels (27, 30), rotatably mounted on the input shaft (22), and driven-side gear wheels (28, 32), rotatably mounted on the driven shaft (24), which can be coupled to or decoupled from the input shaft (22) and/or the driven shaft (24) by means of shifting elements (SE-C, SE-F). According to the invention, the two driven-side gear wheels (28, 32) of the two wheel planes (RE-1, RE-2) are arranged in a rotationally fixed manner on a driven-side hollow shaft (29), which is rotatably mounted on the driven shaft (24) and which can be coupled to the driven shaft (24) via exactly one shifting element (SE-F). The two drive-side gear wheels (27, 30) of the two wheel planes (RE-1, RE-2) can be coupled in alternation to the input shaft (22) via exactly one second shifting element (SE-C). |
