What does the three differential locks in off-road vehicles mean?

[Cole]

Three differential locks refer to the central differential lock, rear differential lock, and front differential lock in off-road vehicles. The following is an introduction to these three locks: 1. Central differential lock: It can make the front and rear wheels rotate at the same speed when wheel slippage occurs, but this is limited to mild road conditions. In cases of cross-axle or artillery shell pits, the central differential lock is not very effective. 2. Rear differential lock: It can make the rear wheels rotate at the same speed as the front axle. Specifically, when an off-road vehicle is driving on a cross-axle or artillery shell pit, and only one wheel has traction while the other is suspended, the vehicle can still move forward with sufficient power. This lock is therefore called the soul of an off-road vehicle. 3. Front differential lock: When one side of the vehicle is suspended, the front differential lock can provide the same power to all wheels, making it known as the life-saving component of an off-road vehicle.
