Abstract:
1. A multi-stage automatic transmission comprising: a drive input shaft (AN) and a drive output shaft (AB); a transfer gearset (VS), configured as a double planetary gearset, having an input element fixed to the drive input shaft (AN); a main gearset (HS), configured as a coupled planetary gearset, with a plurality of uncoupled input elements and an output element that is fixed to the drive output shaft (AB); at least first, second, third, fourth, fifth, and sixth shift elements (A, B, C, D, E, F); an output element of the transfer gearset (VS) rotates at a slower speed than an input rotational speed of the drive input shaft (AN); a first element of the transfer gearset (VS) is connected with a transmission housing (GG) of the multi-stage automatic transmission; an input element ( an output element ( an input element ( an output element ( an input element of the third shift element (C) is connected with the transmission housing (GG); an output element ( an input element of the fourth shift element (D) is connected with the transmission housing (GG); an output element ( an input element ( an output element ( an input element ( an output element ( the sixth shift element (F), when spatially viewed, is located at least substantially on a side of the main gearset (HS) opposite from the transfer gearset (VS); and the third shift element (C) is one of, when spatially viewed, located at least partially on the side of the main gearset (HS) opposite from the transfer gearset (VS) or at least partially radially over the main gearset (HS).
