Embodiment Construction
[0032] Figures 1 to 9 Various embodiments of the multi-stage transmission according to the invention for vehicles, in particular motor vehicles, in planetary gear construction, for example as an automatic eight-speed transmission or an automatic transmission, are shown, Figure 10 An example of a shift map for realizing the different gears is shown.
[0033] Regardless of the specific embodiment, the multi-stage transmission is only shown schematically as a gear set with a housing 9 . The drive unit An and the output unit Ab are likewise shown schematically, for example as an internal combustion engine. The proposed multi-stage transmission comprises six shafts 1 , 2 , 3 , 4 , 5 , 6 and a fixed housing coupling 0 . Furthermore, at least one electric machine EM as well as a first planetary gear set RS1 , a second planetary gear set RS2 and a third planetary gear set RS3 are provided, wherein the drive unit An, for example as an internal combustion engine, can be operated via...
