FIELD: engine building.

SUBSTANCE: invention relates to gearbox with dual clutch for vehicles. Gearbox has a first input shaft and a second input shaft, two clutch couplings (2, 3), two parallel shafts (13, 14) arranged in parallel, pairs of gear wheels from fixed wheels and freely mounted wheels, connecting devices, by means of which freely installed wheels can be optionally connected to corresponding intermediate shaft, and one driven gear wheel (21, 26) installed on two intermediate shafts (13, 14). Driven gear wheels of two intermediate shafts (13, 14) are engaged with gear wheel (23) of differential and each can be alternately connected without possibility of cranking by means of one of connecting devices (22, 27) with corresponding intermediate shaft. Provided is additional intermediate set (25) of gear wheels, wherein one gear wheel (30) of said intermediate set (25) of gear wheels sits on first or second countershaft, another gear wheel (29) of said intermediate set (25) of gear wheels is installed on the third intermediate shaft (31) and on the third intermediate shaft (31) the third driven gear wheel (32) is installed, which is engaged with one of driven tooth-wheels of the first or the second intermediate shaft.

EFFECT: higher number of gears without increasing gearbox dimensions and increasing its weight.
