What does '4WD with three differential locks' mean?

[ElianaFitz]

4WD with three differential locks refers to a four-wheel-drive vehicle equipped with front axle, center, and rear axle differential locks. The front axle differential lock primarily ensures that all wheels receive equal power distribution, the center differential lock synchronizes the rotation speed of front and rear wheels when wheel slippage occurs, and the rear axle differential lock maintains identical rotation speeds between the rear wheels and front axle. Most 4WD urban SUVs come standard with a center differential lock. Below is an extended explanation: The necessity for differential locks: Every vehicle is equipped with a differential, whose primary function is to allow left/right or front/rear drive wheels to rotate at different speeds. Without a differential, front-wheel-drive vehicles would easily experience tailspin during cornering. To maintain consistent rotational speeds during curved driving, differential locks become essential.
