5.4.7 Differential negative impact
However, the operation of the differential and its result is positive only in case of movement on a dry road. Under certain conditions, the differential can adversely affect the movement of the car.
Thus, in case if one of the wheels hits a slippery surface (ice, mud) due to insufficient adhesion to the road, it starts slipping. In case of a significant deterioration in the adhesion of the slipping wheel to the road, the tractive effort on it becomes very low. In this case, the second wheel, which has sufficient adhesion to the road, stops, since due to the property of the differential to distribute the force (torque) between the wheels equally, the tractive effort on the second wheel also becomes very small and insufficient for the movement of the car. The skidding wheel rotates at twice the speed and the car stops completely.
