Wheel-drive models have a torque from the engine is transmitted to the all-wheel drive. As a result of the automatic locking device intermediate differential occurs optimum distribution of engine power corresponding to the method of driving and road conditions. Therefore four-wheel drive cars equally well behaved when driving on highways and motorways, in normal conditions and in unfavorable and in off-road conditions. The torque from the engine is transmitted through the gearbox and an intermediate differential on the front axle differential, and from it - through the propeller shaft - on the rear axle differential. When driving on a dry coating of the torque is distributed evenly on all wheels of the front and rear axle. If a wheel on one axle lose their grip on the edge and will slip or slip, the intermediate differential, without reducing the amount of torque automatically locks the wheels of the axle, transferring a large amount of torque at the wheels of the other axle having a normal grip. The distribution of torque to the wheels at the four-wheel drive models uneven and depends on the degree of coupling the front or rear wheels on the road. Differential 4
(Fig. 8.81) has a main reverse gear clutch which disengages the drive of the rear wheels when braking the motor.
