What is the role of the truck's heavy differential?

Trucks are an indispensable tool in modern logistics and transportation, and differentials are a vital part of truck operation. Its function is to coordinate the rotation speed of the wheels, prevent the vehicle from slipping when turning, and improve driving safety and driving stability.

During the busy logistics transportation process, truck drivers will inevitably encounter turning scenes. Under normal circumstances, the rotation speed of the left and right wheels is the same, but when turning simultaneously, it is necessary to use a point as the center of the circle to drive in a curve. Therefore, when cornering, the inside wheel must spin less and the outside wheel must spin faster. If the rotation speeds of the inner and outer wheels are different, the truck will slip and affect driving safety.

The role of the differential is to distribute power to the appropriate wheels based on the speed difference between the wheels. It adjusts the rotational speed of the wheels and prevents slippage by transmitting power to the gears of the inner wheel and the outer wheel. The differential also improves the traction of the truck, allowing the wheels to move better under the friction of the road.

Of course, at highway speeds, the differential becomes a speed-limiting culprit as it causes a loss of engine power, slowing the truck down. Therefore, some high-end trucks are also equipped with a modern electronic control system, which can adjust the differential according to the vehicle speed, so that the differential can play a better role when turning, and will not cause too much loss when driving at high speed.

The role of the truck differential is to coordinate the rotation speed of the wheels, prevent the vehicle from slipping when turning, and improve driving safety and driving stability. For truck drivers who have been engaged in logistics transportation for a long time, a deeper understanding and mastery of their role can enable them to drive trucks more skillfully, improve transportation efficiency, and ensure material safety.
