Abstract
A multi-speed transmission in planetary design for a vehicle includes a first shaft () provided as a drive (An) and a second shaft () provided as an output (Ab) that is arranged axially parallel to the drive. Three planetary gear sets (RS, RS, RS) and additional shafts (), along with six shifting elements (K, K, K, K, B, B) are provided, through which actuation of several gears is realized. Machine elements (ST, ST) are provided for the transfer of torque between the drive (An) and the output (Ab), whereas the first shaft (), as a drive, is connectable to the sun gear (SR) of the third planetary gear set (RS), to the sun gear (SR) of the second planetary gear set (RS), to the planetary gear carrier (PT) of the third planetary gear set (RS), and is connectable or connected to the sun gear (SR) of the first planetary gear set (RS). The second shaft () is connected or connectable, as a drive (Ab), to the first machine element (ST) and to the second machine element (ST).
