What does 'several locks' mean in off-road vehicles?

[OPreston]

An off-road vehicle typically has three locks, which refer to the central differential lock, rear differential lock, and front differential lock. The details are as follows: 1. Central differential lock: It ensures the front and rear wheels rotate at the same speed when wheel slippage occurs, but this is only effective in mild road conditions. It has limited use in scenarios like cross-axles or artillery shell craters. 2. Rear differential lock: It synchronizes the rotation speed of the rear wheels with the front axle. This is particularly useful when the off-road vehicle encounters cross-axles or artillery shell craters, where one wheel may lose traction while the other is suspended in the air. With this lock engaged, the vehicle can still move forward with sufficient power, earning it the reputation as the soul of an off-road vehicle. 3. Front differential lock: When one side of the vehicle is suspended in the air, the front differential lock ensures all wheels receive equal power distribution. This feature is often referred to as the life-saving component of an off-road vehicle.
