FIELD: transport engineering; transmissions of off-road vehicles. SUBSTANCE: proposed transmission has clutch, gearbox, propeller shafts, rear axle final drive, wheel drives and transfer case with interaxle and center differentials. Transmission has successively interlocking clutch installed concentrically relative to one of axle-shafts of vehicle driving wheel drive on splines in bore of interaxle differential housing for axial displacement from initial position. Housing of center differential has elongated hub with inner splined surface. Axle-shaft gear shank is shorter than hub of center differential and is provided with outer splined surface. With clutch in first position, its outer splines are engaged with housing of center differential, and with clutch in second position, it is engaged through its inner splines with axle-shaft gear of driving wheel drive.
