ABSTRACT:
A multistage transmission for an internal combustion engine has a disconnect-type clutch, a drive shaft and a driven shift on which engaged gear wheels are arranged to achieve different gear steps. Clutches actuated via shift forks are used to move the speed gears to generate a frictional connection with the gear shaft. The gear change is effected by a control cable and/or gearshift linkage. The gear pairs for the even gears and for the odd gears are arranged side-by-side like a dual clutch gear set. To implement an H shift pattern to actuate the clutches of the even gears and the odd gears a shifter shaft is provided, respectively. The two shifter shafts can be controlled via a common selector and/or shift control system.
