What is planetary differential?

A planetary differential is a type of differential gear system used in automobiles. It is used to distribute the power generated by the engine to the wheels evenly, allowing for better handling and stability during turns and on different types of terrain.

The planetary differential consists of three basic components - the sun gear, the planet gears, and the ring gear. The sun gear is attached to the drive shaft coming from the engine. The planet gears are mounted on a carrier that can rotate around the sun gear. The ring gear is mounted around the planet gears and is connected to the axles that drive the wheels.

When the vehicle turns, the planet gears rotate around the sun gear and the ring gear turns in the opposite direction. This allows the wheels to rotate at different speeds while still receiving the same amount of power from the engine.

The planetary differential can also provide torque vectoring, which means it can send more power to the wheel with better traction, thereby improving the vehicle's performance and handling in different driving conditions.

Overall, the planetary differential is an essential component of modern automobiles, allowing for better handling, stability, and performance on a variety of surfaces, terrain, and driving conditions.
