FIELD: machine building.
SUBSTANCE: invention relates to gear boxes (GB) with two clutches. A double clutch is arranged at the gear box input, part of driven disks in the said clutch is installed on the primary GB shaft, while the other part is arranged on a tubular shaft. The above shafts are fitted by gears engaged with the gears of a layshaft where five gears are installed with two of them being engaged with the gears freely mounted on the secondary shaft; a three-position shift collar is installed between them. A gear engaged with the layshaft gear is freely mounted on a tubular end of the secondary shaft and the three-position shift collar is installed there as well.
EFFECT: expanded performance and layout characteristics of a vehicle by increasing its cross-country capacity and making its control easier, better GB durability due to increased rigidity of shafts at their shorter length.
