The Ford Mondeo also has a version with a non-disconnectable all-wheel drive. Additional units are required to drive the rear wheels. The front and rear axles are connected by a cardan shaft. The cardan shaft drives the rear axle differential, from which power is transmitted by two half-axle cardans to the wheels. To ensure the possibility of different numbers of revolutions of the front and rear wheels, for example, when turning, an additional power take-off box (interaxle differential) is required on a car with permanent all-wheel drive. The transfer case is made in the form of a planetary row with a sun and planetary gear. It ensures the distribution of power: 58% to the front wheels and 42% to the rear. Between the revolutions of the front and rear wheels, for example, when the front wheels slip, the usual anti-slip braking system comes into effect, see paragraph 15.19. The transfer case is flanged directly onto the gearbox and is driven by the front axle differential teeth. The transfer case has a separate lubrication system, the oil in which, like the gearbox oil, does not require replacement throughout the entire service life of the vehicle. Repair of the differential should only be carried out in specialized workshops.
Warning! When towing a four-wheel drive vehicle, pay attention to some instructions, see paragraph 25.2.
