FIELD: transport.
SUBSTANCE: invention relates to vehicles and can be used in towing trucks, tractors, road-building and other machines. At the inlet of transmission dual clutch (3) is located. Part of driven disks (28) of this clutch is installed on the main drive shaft (5), and the other part (29) - on tubular shaft (8). On these shafts gears are mounted which are engaged with gears of intermediate shaft (9) on which six gears are mounted, two of which are engaged with gears (19, 20) freely mounted of the secondary shaft (6). Between them, three-position shift collar (22) with reverse driven gear (23). On the tubular tip (7) of the secondary shaft (6), the gear (18) is freely mounted which is engaged with the gear (12) of intermediate shaft (9), and three-position shift collar (21) is located.
EFFECT: invention is aimed to enhancement of operational and layout characteristics of a vehicle by means of improvement of its floatation and facilitation of control due to pairwise gear shifting by dual clutch virtually without power flow interruption, as well as due to increased range and durability of transmission because of increasing rigidity of shafts while decreasing their length.
