FIELD: transport.
SUBSTANCE: claimed gearbox comprises dual clutch assembly, housing with parallel input shafts, output shaft, countershaft and extra shaft. Two input shafts are fitted one into another, one supporting the gears of even gearing and another support the gears of odd gearing. Said gears engage with constant mesh gears of appropriate gearing that rigidly engage with shafts with the help of clutches. Output shaft is aligned with input shaft and engaged therewith by the clutch. Output and countershaft gears are rigidly fitted thereat to make a gear set. The clutch, reverse gear and/or that in constant mesh with input shaft, or gears in constant mesh with input shaft gears are fitted on extra shaft. The gear free running on extra shaft is engaged by the clutch and via tubular shaft with extra shaft gear.
EFFECT: high degree of unification, lower costs of production and repair.
