When to Use the Central Differential Lock?

[DiMary]

Central differential lock can be used when the vehicle is passing through muddy roads. When the vehicle is stationary, press the clutch pedal and activate the inter-axle differential lock switch in the cabin. Once the inter-axle differential is engaged, the differential lock indicator light will illuminate. In extremely poor road conditions, using both the inter-axle differential lock and the inter-wheel differential lock simultaneously can make driving easier and more manageable. Introduction to Central Differential Locks: 1. Forced Locking Type: This type is equipped with a differential lock on a standard symmetrical differential. It features a simple structure, easy manufacturing, and a high torque distribution ratio. However, it is inconvenient to use as it requires stopping the vehicle for operation. Failure to disengage the differential lock promptly may cause other issues. 2. High-Friction Self-Locking Type: This differential lock uses the friction torque generated by the relative sliding of friction plates to lock the differential. It is commonly found in passenger cars or light vehicles but has higher manufacturing requirements, significant wear on friction components, and higher costs. 3. Torsen Type: This is a new type of differential lock widely used in all-wheel-drive passenger cars. It has a compact structure, a wide and adjustable torque transmission range, but cannot be used as an inter-wheel differential lock on the front drive axle.
