FIELD: mechanical engineering.
SUBSTANCE: invention refers to transport engineering, particularly to gear boxes of vechicles. The double gear is installed at input to the gear box. Part of driven disks of this gear is installed on the primary shaft of gear box - GB, while another part is arranged on a tubular shaft. On these shafts there are mounted gears meshing the block of gears freely mounted on the intermediary shaft, whereon three gears are assembled. The secondary shaft with two freely placed on it gears is set coaxially to the primary shaft; triple-station range clutch is arranged between these shafts. The double range clutch consisting of two half-couplings tied with a shift fork is positioned between middle pairs of gears.
EFFECT: expanded operation functionality of vehicle.
