Description

technical field

[0001] The invention belongs to the technical field of vehicle drive train manufacturing, and in particular relates to a differential in a vehicle drive train. Background technique

[0002] The function of the differential in the vehicle transmission system is to allow the left and right wheels to rotate at different speeds when the car is turning or driving on an uneven road surface, so that the wheels do pure rolling on the ground. figure 1 It is a simplified structural diagram of an automobile differential in the prior art. figure 1 Among them, the automotive differential is mainly composed of an input gear 1, a planetary carrier 2, two planetary gears 3 and two output gears 4. Wherein, the planetary gear carrier 2, the planetary gear 3, the output gear 4, etc. constitute a planetary assembly. The input gear 1 is connected to the outer casing of the planetary assembly, and its work content is: to transmit the entire torque output by the gearbox, and driv...
