FIELD: machine building. SUBSTANCE: device has covered casing, drive shaft with a gear of reducing gear coaxial to the drive shaft of rear axle drive and equipped with a device for interlocking. Driven shaft of front axle drive equipped with a wheel of cylindrical gear for coupling driven shafts with interlocking device. There is also a system to control interlocking devices. It is provided with a mechanism to prevent concurrent switching on of the direct transmission and reducing gear and device for switching off rear axle drive with direct gear on. The transfer gear-box has such members interconnected in series as planetary drive internal wheel of which is coupled through safety device against limit loading with reducing gear wheel. External wheel is related to the casing. Carrier is connected the casing tail through a gear. Planetary drive is placed between reducing gear wheel and drive shaft wheel of rear axle drive. Reducing gear wheel engages drive shaft. EFFECT: high efficiency. |
