Vehicle transmission with progressive stepping

摘要

In a transmission (2) for a motor vehicle with a main transmission part (22) which possesses a plurality of gear steps and wherein, between each step a step-jump in the gear ratio is provided, and with a split transmission part (40) for the separation of the step-jumps of the gear steps of the main transmission part (22) and with an area group transmission part (10) for the extension of the over-all gear ratio of the gear steps of the main transmission part 22 with a slow and a rapid gear ratio area, the average gear step-jump of the upper gear steps is approximately at least 0.7% less than the geometric step-jump calculated theoretically from the total gear ratio.
