Analysis of Automobile Differential and Four-wheel Drive Structure

The car differential is a device used to adjust the difference in wheel speed on both sides of the car. It allows the wheels on both sides to rotate at different speeds when turning or on different road conditions, thereby improving the vehicle's driving stability and handling. The four-wheel drive structure distributes power to the four wheels, providing better traction and grip, and is suitable for off-road driving or slippery roads. The car differential and four-wheel drive structure are important components of modern cars and have a significant impact on the performance and safety of the vehicle.
