[WapCar] The central differential lock is a locking mechanism installed on the central differential, and used for four-wheel drive vehicles. Its function is to improve the passing capability of the vehiclle on the bad roads, that is, when one of the drive axles of the car is idling, it can rapidly lock the differential and make the two drive axles become a rigid connection. In this way, most of torque or even all torque can be transmitted to the non-slip drive axles, making the best use of its adhesion to produce enough traction to enable the vehicle to continue driving.
Although the part-time four-wheel drive vehicle has a front and rear 50:50 power locking function, it does not have this function because it does not have a central differential, such as Wrangler, Haval H5 and other models. However, not all vehicles with a transfer case do not have a central differential locking function, for example, the Mercedes-Benz G-Class and Mitsubishi’s super-selected four-wheel drive, they add a central differential to the transfer case, so the basis for having this function is that it is possible to have this function on the basis of a central differential.
