The differential is provided for adjusting the rotational speed difference between the left and right wheels.
Fig. 1 is a schematic cross-sectional structure of a differential provided in an embodiment of the present application, and as shown in fig. 1, the differential is composed of planetary gears 200, a differential case 300, side gears 400, and so on. The power of the engine enters the differential mechanism through the transmission shaft to directly drive the differential mechanism housing 300, and then the planetary gear 200 drives the left half shaft and the right half shaft to respectively drive the left wheel and the right wheel. Meanwhile, in order to alleviate friction between the side gears 400 and the planetary gears 200 and the inner surface of the differential case 300 while rotating, the related art generally provides a differential spacer between the gears and the inner surface of the differential case 300 to extend the service life of the gears and the differential case 300.
