1. A power shiftable multi-stage transmission (120), of a planetary design, being disposed between an input drive shaft (AN) and an output shaft (AB) for a vehicle (100), the multi-stage transmission comprising:

  • two parallel shaft trains (WS1, WS2),first, second, third, fourth, fifth and sixth shift elements (K1, K2, K3, K4, B1, B2), wherein the first, the second, the third, and the fourth shift elements (K1, K2, K3, K4) are clutches and the fifth and the sixth shift elements are brakes (B1,B2),at least first and second spur gear stages (STS1, STS2),first, second and third planetary gear sets (PS1, PS2, PS3), and each of the first, the second and the third planetary gear sets (PS1, PS2, PS3) comprising a sun gear (SO1, SO2, SO3), a ring gear (HO1, HO2, HO3) and a planet carrier (ST1, ST2, ST3) having multiple planetary gears,the two shaft trains (WS1, WS2) being connectable with one another via the at least first and the second spur gear stages (STS1, STS2), anddifferent transmission ratios, between the input drive shaft (AN) and the output shaft (AB), being achieved by selective engagement of at least three of the first, the second, the third, the fourth, the fifth and the sixth shift elements (K1, K2, K3, K4, B1, B2) such that at least nine forward gears and at least one reverse gear can be implemented.
