Power drive system and vehicle with same

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, a first electric generator and a second electric generator; the differential mechanism comprises a first planet carrier, a second planet carrier, first planet wheels, second planet wheels, a first gear ring and a second gear ring, wherein the first planet wheels are connected to the first planet carrier, the second planet wheels are connected to the second planet carrier, the first planet wheels mesh with the first gear ring, and the second planet wheels mesh with the second gear ring and mesh with the first planet wheels; the input part, the first planet carrier and the second planet carrier are coaxially linked; the power output shaft is arranged to be linked with the input part; each input shaft is arranged to be linked with the power output shaft; and the first electric generator is linked with the first gear ring, and the second electric generator is linked with the second gear ring. According to the power drive system, the differential mechanism realizes the differential function through the planetary differential principle, and the structure is compact and simple.

Description

Technical field [0001] The invention relates to a power drive system for a vehicle and a vehicle with the power drive system. Background technique [0002] In a differential technology known to the inventor, the differential includes the driven gear of the main reducer, the main reduction driven gear), planetary gears, sun gears, etc. The planetary gears are mounted on the slave through a square shaft and a sleeve. The auxiliary plate of the movable gear meshes with the center wheel. The rotation and movement functions of the rotating pair and the plane moving pair are realized. The center wheel is connected with the left and right half shafts through angular positioning pins and cylindrical pairs or splines to achieve output rotation. The purpose of the moment. This kind of differential cancels the original left and right housings of the differential, planetary gear shafts and other components, and uses square shafts and sleeves to directly install the planetary gears on the au...

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
