All-wheel drive vehicles are designated word SYNCRO. To drive the rear wheels on the car sets allow further transfer box, propeller shaft, rear final drive and rear drive shafts. To equalize the speed front and rear wheels, a special differential. In addition, a special differential distributes torque between the front and rear axle of the car. If slippage of the wheels on one axle of the vehicle the torque transmitted to the other axle, automatically increases. This improves the traction of the car and the road surface. On the axis where the contact of the wheels and the road surface reduces Xia, also decreases the torque transmitted to the axle, resulting in increased resistance to skidding car. Regardless of this special permits differential rotation of the wheels at different speeds, which is necessary for the normal operation of the anti-lock braking systems. Torque distribution is made in a special differential gear with the worm wheel and the differential. Special differential operates autonomously, without control signals. Technical parameters of the differential determined by the parameters of the differential screw. The basic principle, which is incorporated in a differential that worm differentials on one side rotate freely and easily, and on the other hand with difficulty or not rotate. The process of redistribution of the torque occurs very quickly and smoothly, while its external manifestations are not noticeable. Special differential is attached to the gearbox housing. Grease differential performed with the same oil as the gearbox. At the same oil change is needed. Rear final drive with differential is filled with gear oil GL5 SAE 90. The amount of oil 1.5 l. Changing the oil in the process of operation of the vehicle is not provided. Checking the oil level via the special opening. Repair of special differential and rear final drive must be carried out only at specialized service stations.
