A power-shiftable multi-stage transmission in planetary design, between a drive shaft and an output shaft, in particular an automatic transmission for a vehicle. The multi-stage transmission has two parallel shaft sections, six shift elements, at least two spur-gear stages and three planetary gear sets, each of which has one sun gear, one ring gear, and one planet carrier having a plurality of planetary gears. The planet carrier is united in a carrier, and the two shaft sections can be connected to one another via the at least two spur-gear stages. Different transmission ratios between the drive shaft and the output shaft can be implemented by selective engagement of the six shift elements such that a plurality of forward gears, in particular nine forward gears, and at least one reverse gear, can be implemented. |
