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. The power drive system comprises a differential mechanism, an input part, a power output shaft, a plurality of input shafts and a first electric generator. The differential mechanism comprises a first planet carrier, a second planet carrier, first planet gears, second planet gears, a first gear ring and a second gear ring. The first planet gears and the second planet gears are connected with the first planet carrier and the second planet carrier correspondingly and engaged with the first gear ring and the second gear ring correspondingly. The second planet gears are further engaged with the first planet gears. The input part is in coaxial linkage with the first planet carrier and the second planet carrier. The power output shaft is arranged to be in linkage with the input part. Each input shaft is arranged to be in linkage with the power output shaft. The first electric generator is in linkage with one input shaft in the multiple input shafts. The differential mechanism of the power drive system utilizes the planet differential principle for achieving the differential function, and the structure is compact and simple.

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...
