FIELD: transport.
SUBSTANCE: invention relates to drives of higher cross-country capacity vehicles with 6x6 axle arrangement. Drive axle drive comprises front, central and read drive axles, transfer box with remote control mechanism. Transfer box comprises drive shaft, driven shafts of the drive of front, central and read drive axles and toothed coupling. Wheel gearboxes of front and central axles are furnished with toothed couplings with remote control mechanism. Central drive axle can be permanently coupled with rear drive axle. Central drive axle final drive gearbox is furnished with toothed coupling with remote control mechanism. Above described drives are controlled by switching device. One section of the latter is consecutively connected with remote control mechanism of front drive axle toothed coupling and remote control mechanisms of toothed couplings of wheel gearboxes. Second section of switching device is consecutively connected with remote control mechanism of central drive axle toothed coupling and remote control mechanisms of toothed couplings of wheel gearboxes.
EFFECT: drive longer life.
