Problems solved by technology

[0003] However, this differential uses a symmetrical bevel gear structure to realize the inter-wheel differential, which is only a partial innovation for the traditional symmetrical bevel gear differential, and cannot really solve the problem that the axial size of this differential structure is too large , shell and bevel gear mass and the shortcomings of relative deviation of reliability

Abstract

The invention discloses a power drive system and a vehicle equipped with the power drive system. The power drive system comprises a differential mechanism, wherein the differential mechanism comprises a first planet carrier and a second planet carrier, a first planet gear and a second planet gear, a first gear ring and a second gear ring, at least one power output shaft, a plurality of input shafts, and a first motor generator; the first and second planet gears are respectively arranged on the first and second planet carriers; the first and second planet gears are respectively meshed with the first and second gear rings; the second planet gear is also meshed with the first planet gear; the power output shaft is designed to be linked with the power input end of the differential mechanism; each input shaft is designed to be linked with the power output shaft; and the first motor generator is linked with one of the power input shafts. The differential speed function of the differential mechanism in the power drive system disclosed by the embodiment of the invention is achieved by utilizing the planetary differential principle; and the power drive system is compact and simple in structure.

Description

technical field [0001] The invention relates to a power drive system for a vehicle, a vehicle with the power drive system. Background technique [0002] In a kind of differential gear technology that the inventor understands, differential gear comprises the driven gear of final reducer (main reduction and driven gear), planetary gear, sun gear etc., and planetary gear is installed on slave gear by square shaft, bushing. The sub-plate of the movable gear is meshed with the center wheel, and its rotation and movement functions are realized by the rotating pair and the planar moving pair. moment purpose. This kind of differential cancels the original left and right differential housings, planetary gear shafts and other components, and uses square shafts and bushings to directly install the planetary gears on the sub-plate of the driven gear of the main reducer, effectively The number of parts of the differential is reduced, the structure is simplified and the weight is reduce...
