What are the reasons for a broken differential?

[McAngelo]

The differential may break due to the following reasons: 1. Improper operation of the differential lock by the driver, failing to disengage the differential lock in time when the vehicle exits rough terrain, leading to damage. 2. Oil level below the normal value, the driver failing to monitor the oil level in time, resulting in insufficient lubrication and subsequent differential damage. 3. Improper bearing clearance, where excessive bearing clearance during assembly causes axis deflection, while insufficient clearance leads to surface burning, pitting, and layer peeling of the rollers. The functions of the differential are: 1. To transmit the engine torque from the universal drive through the main reducer, differential, and half-shaft to the driving wheels, achieving speed reduction and torque increase. 2. To change the direction of torque transmission through the bevel gear pair of the main reducer. 3. To enable differential action between the two wheels through the differential, ensuring that the inner and outer wheels turn at different speeds.
