What is the main function of a car differential?

[VanEliza]

Here is an introduction to the main functions of a car differential: Power transmission: Transmits the power output from the engine to the wheels. Speed reducer: Divides the torque already increased by the main reducer into two parts and distributes it to the left and right half-shafts. Acts as the main reduction gear: Serves as the main reduction gear, reducing the speed of the drivetrain before transmitting power to the wheels, and allows the wheels on both sides to rotate at different speeds. When the car turns, the distances traveled by the wheels on both sides are unequal within the same time—the outer wheel moves a greater distance than the inner wheel. As a result, the planetary gears on the differential cross shaft are affected by the resistance of the wheels. While revolving, they also rotate on their own, automatically increasing the speed of the outer wheel, speeding it up, and slowing down the inner wheel, thus performing the differential function.
