What does 3 differential locks mean?

[DelCollin]

3 differential locks refer to: 1. Differential lock 1 makes the front and rear axles rotate at the same speed, suitable for situations where there is gravel or slight bumps causing the front or rear wheels to slip; 2. Differential lock 2 makes the two rear wheels rotate at the same speed as the front axle, used when encountering larger rocks or more severe bumps on the road; 3. Differential lock 3 ensures all wheels have the same power, used for more complex road conditions or when all wheels on the same side lose traction. Differential locks can be considered as differentials with automatic locking functions. Common types of differential locks include friction plate and cone types, and their effectiveness is determined by the locking coefficient. The locking coefficient refers to the maximum possible multiple of torque difference between the two half-shafts, and the locking effect increases with the input torque and torque difference.
