What does the three differential locks in a car mean?

[EvanMarie]

Car three differential locks refer to the central differential lock, front axle differential lock, and rear axle differential lock. Differential lock means when one driving wheel slips, the differential housing and the half shaft are locked together, causing the differential to lose its differential function, allowing all torque to be transferred to the other driving wheel. Extended information about the three differential locks is as follows: 1. For a full-time drive system with three differentials and a simple form, due to the equal torque effect of the differential, the vehicle may get stuck if any wheel loses traction. 2. The solution is to use the differential lock to lock the half shaft of the wheel that has lost driving force, so that the wheel no longer affects the power distribution. 3. It can be seen that the biggest role of the differential lock is to ensure that other driving wheels can still obtain sufficient driving force when a wheel slips.
