Q:The role of off-road truck differential lock?
Automatic mechanical lock differential The basic structure of this type of differential and mechanical lock differential is the same, the difference is that the mechanical lock differential lock and unlock, completely by the driver manual control; automatic mechanical lock differential It is locked and unlocked according to road conditions. Its locking detection mechanism is very sophisticated, there are two detection, one is the difference between the differential gear and the differential shell, and the other is the speed of the differential shell. Locking conditions: differential housing speed does not exceed the set value (that is, the vehicle speed is lower than the set value), variable gear and differential shell speed difference exceeds the set value (left and right wheel speed difference is too large) If both conditions are met, the differential lock will be triggered and the normal steering will not cause it to lock. The entire locking process, the wheel idling angle difference of not more than 360 degrees. Unlock condition: The speed of the differential shell exceeds the set value (the speed exceeds the set value). The torque of the left and right axles is reversed (the vehicle turns on), and any one of them will be unlocked immediately. Advantages: Highway driving characteristics and open differential exactly the same. The off-road surface, exactly the same as the locked differential, does not twist the axle due to steering, and its locking and unlocking process is completely automatic and does not require human intervention. Reliability is very high. Disadvantages: lock the noise is relatively large, the structure than the mechanical lock differential complex, each differential can only be applied to a model, not versatile. Applicability: can directly replace the open differential, the precursor can be used after the drive, there is no applicability of the restrictions.
