Which is more effective, front axle differential lock or rear axle differential lock?
1 Answers
They are equally important and indispensable. The function of the front differential lock is to control the power distribution between the two front wheels, while the rear differential lock controls the power distribution between the two rear wheels. The central differential lock manages the power distribution between the front and rear axles, i.e., the distribution between the two front wheels and the two rear wheels. Below is a related introduction to front and rear axle differential locks: 1. Function: Simply put, the differential lock stops the differential from working, enabling both wheels on an axle to rotate synchronously. 2. Principle: When the left and right wheels are on surfaces with different coefficients of adhesion (e.g., one side on ice and the other on pavement), the wheel on the low-adhesion surface can generate very little driving torque (due to insufficient friction at the wheel end, making it unable to obtain the required reaction force). Meanwhile, the wheel on the high-adhesion surface can only receive almost the same driving torque, which is insufficient to make the wheel on the high-adhesion surface roll forward (this is unrelated to engine power and only depends on the difference in adhesion coefficients between the two wheels at that moment). Therefore, even if the accelerator is pressed hard, it will only cause the wheel on the low-adhesion side to lose traction and spin, while the wheel on the opposite side cannot move forward due to insufficient driving torque. This explains why when one wheel spins, the other wheel remains stationary.
