What does the lock on an off-road vehicle mean?

[McEden]

Off-road vehicle lock refers to the differential lock. The following are introductions to three types of differential locks: 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 use in mild road conditions. If it is a cross-axle or artillery pit, the central differential lock has little effect. Rear axle 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 pit, and only one wheel has traction while the other is suspended, the vehicle still has enough power to move forward. This lock is therefore called the soul of an off-road vehicle. Front axle differential lock: When one side of the vehicle is suspended, the front axle differential lock can enable all wheels of the vehicle to receive the same power. Therefore, the front axle differential lock is called the life-saving component of an off-road vehicle.
