Power driving system and vehicle with same

Abstract

The invention discloses a power driving system and a vehicle with the same. The power driving system comprises a differential, a power output shaft, multiple input shafts, and a first electric generator, wherein the differential includes first and second planet racks, first and second planet gears, and first and second gear rings; the first and second planet gears are respectively arranged on the first and second planet rack, and are respectively engaged with the first and second gear rings; the second planet gear is engaged with the first planet gear; the first planet gear and the second planet gear are different in revolving radius; the power output shaft is linked with a power input end of the differential; each input shaft is linked with a power output shaft; and the first electric generator is linked with one of the multiple input shafts. The differential of the power driving system uses a planet differential principle for realizing a differential function, and 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...

AI Technical Summary

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
