Car differential lock

Differential locks are available in various forms. Commonly used are friction plates and cones. Their effects are determined by the locking factor. The locking factor is the maximum multiple of the torque that may differ between the axles on both sides. The locking effect increases with the input torque and torque difference. Modern differential locks also use electronic control to adapt to changing conditions of use.

The role of differential lock is when a drive wheel skids, the differential case and the semi-shaft locked into one, so that the differential loses differential effect, you can transfer all the torque to the other side of the drive wheel.

Differential locks can be considered as differentials with automatic locking.

For a three-way differential, the simplest type of full-time drive system, because of the equal torque of the differential, the vehicle may be in trouble because of the loss of adhesion of any one wheel, especially for those who often pass through the muddy road and other harsh road conditions. Vehicles. The solution is to use a differential lock to lock the axle shaft of the lost drive wheel so that the wheel no longer affects the power distribution. The greatest function of the visible differential lock is to ensure that the other drive wheels can still obtain sufficient driving force when the wheels are slipping.

For full-time drive vehicles, the car is equipped with three differentials, four wheels can be rotated at different speeds, and different torque distributions are automatically obtained according to their different ground adhesion to ensure that the vehicle has good driving force. . For most full-time 4WD vehicles, due to the central differential, when a certain drive wheel slips, it will consume all the engine power on the slipping wheels. Therefore, it must be manually operated (some of them are only inside the car. A button) differential lock locks the center differential housing and the axle half together, causing the differential to lose differential action and transfer the torque to another drive axle.
