A differential is a mechanical assembly found in most vehicles with multiple wheels, in the automotive sector and other off-road vehicles. Its main function is to allow the wheels to spin at different speeds while still receiving power from the driveshaft. This is essential for a smooth and safe turn, since the inside and outside wheels of a vehicle must travel different distances when turning a corner. The differential also helps transmit power evenly between the wheels for optimal traction. It can be an open, limited slip or locking differential, each with distinct characteristics suitable for various driving conditions.
