Under adverse road conditions, it may happen that the torque transmitted by a conventional differential will not be perceived by one of the wheels, which will begin to slip. The danger of such slipping is largely prevented by a self-locking differential (with a blocking ratio of about 25%). In practical operation, this means improved traction when starting off and accelerating (in the adverse road conditions mentioned above), as well as when cornering in a sporty manner.
However, at the same time, a car moving on a road with a non-uniform surface and a varying coefficient of adhesion of wheels to the road, in the mode of variable load on the engine and with a high degree of use of its power, shows an increased tendency to turn around a vertical axis passing through its center of gravity. Overcoming this negative inclination requires the driver to increase the tension and special attention that is necessary for a sporty driving style.
The self-locking differential works without driver intervention.
