Abstract

A transmission where a first shaft is rotationally fixable to a third shaft and to a second shaft, the second and third shafts are rotationally connectable to a fourth shaft, the second shaft is rotationally connectable to a fifth shaft, the fourth shaft is rotationally connectable to the fifth shaft, the third shaft is rotationally connectable to the fifth shaft, fixed gears of the fourth and fifth shafts are rotationally connected to a drive output, a first gearwheel of the sixth shaft meshes with a fixed gear of the second shaft, and a second gearwheel of the sixth shaft meshes with a fixed gear of the third shaft. Moreover, a first gearwheel of the sixth shaft is an idler gear and a second gearwheel of the sixth shaft is a fixed gear, or vice versa. Additionally, the idler gear of the sixth shaft is rotationally fixable to the sixth shaft.
