Abstract:
A planetary multi-speed transmission with a housing is proposed for a vehicle. A first shaft is provided as a drive and a second shaft is provided as an output, axially parallel to the drive. Three planetary gear sets and additional shafts, along with six shifting elements, are provided, through which the actuation of several gears can be realized. Machine elements are provided for the transfer of torque between the drive and the output. The first shaft is connectable, as the drive, to the sun gear of the second planetary gear set, to the sun gear of the first planetary gear set, to the planetary gear carrier of the second planetary gear set, to the planetary gear carrier of the first planetary gear set, and to the first machine element. The second shaft is connected or connectable, as a drive, to the first machine element and to the second machine element.
