What is the working principle of four-wheel drive?

[MaverickDella]

The following is the working principle of four-wheel drive: 1. Four-wheel drive, also known as all-wheel drive, means that both the front and rear wheels of the car have power. The engine output torque can be distributed in different proportions to all front and rear wheels according to the state of the driving surface to improve the driving ability of the car. 2. The SH-AWD (Super Handling All-Wheel Drive) system is Acura's unique four-wheel drive system. This epoch-making four-wheel drive system not only automatically distributes torque between the front and rear wheels but also achieves a breakthrough by freely distributing torque between the left and right rear wheels, allowing all four wheels to be allocated the optimal torque as needed.
