  • Dependency transmission
    Patent number: 9291242
    Abstract: The disclosure relates to a transmission for a motor vehicle, wherein the transmission comprises an input shaft, at least first and second countershafts, and an output shaft. The input shaft is provided with a first driving gearwheel, which interacts with a first gearwheel arranged upon the first countershaft, and a second gearwheel arranged upon the second countershaft. A number of gear teeth of the first gearwheel is selected such that, in relation to the number of gear teeth of the first driving gearwheel, the number of gear teeth of the first gearwheel can be either reduced or increased with at least one gear tooth, without affecting the number of gear teeth upon the first driving gearwheel, whereby the reduction or increase in the number of gear teeth of the first gearwheel is compensated with a profile shift of the gear teeth of the first gearwheel.
