Power-driven system and vehicle with same

Abstract

The invention discloses a power-driven system and a vehicle. The power-driven system comprises a differential, a power output shaft, multiple input shafts and a first electric generator, wherein the differential comprises a first planet carrier, a second planet carrier, a first planet gear, a second planet gear, a first gear ring and a second gear ring, the first planet gear and the second planet gear are arranged on the first planet carrier and the second planet carrier respectively, the first planet gear and the second planet gear are meshed with the first gear ring and the second gear ring respectively, the second planet gear is further meshed with the first planet gear, the revolution radius of the first planet gear is different from that of the second planet gear, the power output shaft is arranged to be in linkage with the power input end of the differential, one of the multiple input shafts is arranged to be in linkage with the power output shaft in a selective mode, other input shafts are arranged to be in linkage with the power output shaft, and the first electric generator is arranged to be in linkage with the above-mentioned input shaft. The differential of the power-driven system achieves a differential function by means of a planet differential principle, 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...

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
