Abstract:
A multi speed transmission in planetary design for a vehicle, the transmission having a housing, a first shaft (1) as a drive (AN), a second shaft (2) as an output (Ab) axially parallel to the drive, three planetary gear sets (RS1, RS2, RS3), additional shafts (3-10), and six shifting elements (K1, K2, K3, K4, K5, B1) actuatable to realize several gear ratios. The transmission further includes machine elements (ST1, ST2) that transfer torque between the drive (AN) and the output (Ab). The first shaft (1) is connected to the planetary gear carrier (PT1) of the first planetary gear set (RS1) and is connectable at least to the sun gear (SR2) of the second planetary gear set (RS2) and to the ring gear (HR3) of the third planetary gear set (RS3). Additionally, the second shaft (2) is connected to the first machine element (ST1) and to the second machine element (ST2).
