What is the working principle of a differential?

[PatrickFitz]

The working principle of a differential is: 1. Power input to the differential, where the driven bevel gear drives the rotation of the differential housing; 2. Power output from the differential, where two side gears are connected to the drive shafts (also known as half-shafts) on both sides, transmitting power to the wheels; 3. The rotation of the planetary gears refers to the rotation of the planetary gears around the planetary gear shaft; 4. The revolution of the planetary gears refers to the rotation of the planetary gears around the axis of the side gears. The automotive differential is a mechanism that allows the left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of left and right side gears, two planetary gears, and a gear carrier. Its function is to enable the left and right wheels to roll at different speeds when the car is turning or driving on uneven roads, ensuring that both drive wheels perform pure rolling motion. The differential is designed to adjust the speed difference between the left and right wheels.
