Abstract
A power shiftable multi-stage transmission of a planetary design and disposed between an input drive shaft and an output shaft for a vehicle. The multi-stage transmission has two parallel shaft trains, six shift elements, at least two spur gear stages and three planetary gear sets. Each of the planetary gear sets has a sun gear, a ring gear and a planet carrier combined in a carrier having multiple planetary gears. The two shaft trains may be connected to one another via the at least two spur gear stages. Different transmission ratios, between the input drive shaft and the output shaft, may be achieved by selective engagement of the six shift elements such that a plurality of forward gears, at least nine forward gears, and at least one reverse gear, may be implemented.
