Ordinary differential is composed of planetary gear, planetary wheel frame (differential housing), half shaft gear and other parts. The power of the engine enters the differential through the drive shaft,
directly drives the planetary wheel frame, and then the planetary wheel drives the left and right two half-shafts, respectively, to drive the left and right wheels.
This role is the most basic role of differential, as for the later development of what central differential, non-slip differential, LSD differential, Towson differential, etc., they are to improve the driving performance of the car
