What does the three differential locks in a car mean?

[Philip]

Car three differential locks refer to the front differential lock, central differential lock, and rear differential lock. For off-road vehicles, having these three locks is equivalent to being the king of off-roading. The function of the front differential lock is to ensure that all wheels receive the same power when one side of the vehicle is lifted off the ground, hence the front differential lock is known as the life-saving component of off-road vehicles. The central differential lock ensures that the front and rear wheels rotate at the same speed when wheel slippage occurs, but this is limited to minor road conditions. In cases of cross-axle situations or artillery shell pits, the central differential lock is less effective. The rear differential lock allows the rear wheels to rotate at the same speed as the front axle, specifically when an off-road vehicle is driving on cross-axle terrain or artillery shell pits, where only one wheel has traction while the other is lifted, the vehicle still has sufficient power to move forward.
