FIELD: machine building.
SUBSTANCE: invention relates to automotive transmissions. Gearbox demultiplier contains two three-link planetary rows, each consisting of a carrier with satellites, a sun gear and a crown gear wheel. Sun gear 23 of the first planetary row is connected to secondary shaft 11 of the gearbox. Carrier 21 of the first planetary row is connected to sun gear 27 of the second planetary row. Carrier 25 of second planetary row is connected with output shaft 29. Demultiplier comprises double-acting coupling 30 for alternately coupling crown prime gear 24 of first planetary row with housing 1 and carrier 21, double-acting clutch 31 for alternate coupling of the crown planetary gear 28 of the second planetary row to housing 1 and to any carrier.
EFFECT: providing a large range of gear ratios, which improves cross-country ability of the vehicle.
