Problems solved by technology

[0007] The purpose of the present invention is to provide a hybrid electric vehicle power splitter and an integral power distribution system to solve the gap between the back of each gear and the housing in the bevel gear planetary gear train caused by using the differential as the power splitter of the hybrid electric vehicle. Sliding friction and bevel gear support effects are not good and other defects, to overcome the problem that the space layout of the existing integral power distribution system is not compact

Abstract

The invention discloses a power distributor and unitary power distribution system of a hybrid power automobile. The power distributor comprises a housing assembly, a bevel gear planetary gear train, a bearing, disk spring parts and shaft parts, wherein power is supplied from the left side of the power distributor via a spline shaft of a left end cover; at least three planetary gears of the bevel gear planetary gear train are driven by the housing assembly to revolute, thereby distributing the power to a right half shaft gear and a left half shaft gear of the bevel gear planetary gear train; finally the power is output from the right half shaft gear spline shaft and the left half shaft gear spline shaft from the right side of the power distributor through the spline. According to the invention, the unitary power distribution system adopts the power distributor; the input shaft of the power distributor disclosed by the invention is arranged at the left side of a device, two output shafts are led out from the right side of the device, so that a power generator of the unitary power distribution system can be arranged in parallel with a motor coaxially, so that the occupied space of the system is reduced; furthermore, the gear has good bearing effect and high revolution precision.

Description

technical field [0001] The present invention relates to a power splitter, and more specifically, the present invention relates to a power splitter and a power splitter applied to a hybrid electric vehicle. Background technique [0002] With the increasingly serious problems of environmental pollution and energy shortage, energy saving and environmental protection have become the two major themes of automobile development at this stage, so electric vehicle technology has gradually become the trend of automobile research and development. However, due to the immature battery technology at this stage, the research and development of pure electric vehicles are greatly restricted. Hybrid Electric Vehicle (HEV, Hybrid Electric Vehicle, generally refers to gasoline-electric hybrid vehicles), as a transitional product between traditional vehicles and pure electric vehicles, has been widely recognized around the world for its low emission and high efficiency and energy-saving features...
