w124 4matic - Mercedes promotion video for USA 1990 #mercedesw124

The Mercedes W124 with 4Matic all-wheel drive system is implemented in a mechanical transfer case, in which the connection of the hydraulic drives occur ZHM liquid supplied under high pressure.

Start the movement always happens with the distribution of effort - 35% on the front axle and 65% on the rear axle. These proportions are saved to a speed of 20km / h (if the movement was the beginning of the acceleration is greater than 0.5m / s, the front-wheel drive is switched on, provided that the rate of acceleration). Then the front-wheel drive is switched off, and the movement continues only on the rear wheel drive. If the difference in wheel speed is more than 2 km / h to a speed of 100km / h or more than 2% in excess of 100km / h, then reconnects the front drive with a moment 35/65%, and remains on for approximately one second after the wheel speed equalized.

In that case after the 35/65% speed of the wheels is not equalized, the center differential lock is switched on, i.e. the time allocated for 50/50%. If in this case the vehicle speed is less than 38km / h, in addition to all the locked rear cross-axle differential. Lock in the 4Matic rear axle can only be activated to 38km / h.
