Double clutch gearbox for vehicle e.g. commercial vehicle, has input shafts and two secondary shafts, where one of input shafts carries set of fixed gears for determining ratio of first and second gear and third and fourth gear

摘要

The gearbox (1) has two input shafts (2, 3) and two secondary shafts (4, 5), where one of the input shafts is concentric with the other input shaft. The former input shaft carries a set of fixed gears (13, 14) for determining ratio of first and second gear and third and fourth gear. The latter input shaft carries another set of fixed gears (15, 16) for determining ratio of fifth and sixth gear and seventh and eighth gear. The fixed gears of the former input shaft are meshed with two idler gears (17, 18).
