Abstract
A manual transmission unit has one transmission input shaft, one transmission output shaft, a first intermediate shaft, a second intermediate shaft, a plurality of gear wheels, of which a first and a second drive gear wheel are arranged on the transmission input shaft and connectable in a rotationally fixed manner thereto, in particular in a permanently rotationally fixed manner thereto, and a plurality of torque transmission units for selective connection of additional gear wheels to at least one of the intermediate shafts. The first drive gear wheel intermeshes together with two intermediate wheels and the second drive gear wheel intermeshes together with two additional intermediate wheels. At least two, preferably at least three and more preferably at least four of the intermediate wheels are selectively connectible to the intermediate shafts for power transmission.
