Abstract

The invention relates to a hybrid power driving system, and belongs to the technical field of hybrid power automobile driving systems. The hybrid power driving system comprises an outer gear ring; a sun gear positioned at the center of the outer gear ring; a plurality of planet gears meshed between the outer gear ring and the sun gear; a planet carrier rotationally connected with the plurality of planet gears; a first input shaft; a second input shaft, wherein one end of the first input shaft is coaxially and fixedly connected with the planet carrier, and one end of the second input shaft is coaxially and fixedly connected with the sun gear; a first synchronizer, which is fixed to the second input shaft so that the second input shaft can be connected with or disconnected from the outer gear ring so that the second input shaft can be connected with or disconnected from a gearbox shell; a differential mechanism, which is in transmission connection with the outer gear ring; and a third input shaft, wherein the axis of the third input shaft is parallel to the axis of the second input shaft, and the third input shaft is in transmission connection with the differential mechanism. According to the hybrid power driving system, the number of gears is reduced by half, the axial size is reduced, and the structure of the hybrid power driving system is simplified.

Description

technical field [0001] The present application relates to the technical field of drive systems of hybrid electric vehicles, in particular to a drive system of hybrid electric vehicles. Background technique [0002] With the increasing awareness of energy conservation and environmental protection in today's society, new energy vehicle technology has begun to develop rapidly. Hybrid vehicle drive technology is the core stage of the development process of new energy vehicles. Improving fuel economy and reducing emissions are important issues facing hybrid technology. [0003] In the related art, there are currently three types of power structures for hybrid electric vehicles: the first is a series structure, the second is a parallel structure, and the third is a hybrid structure. [0004] A car with a parallel structure means that it is mainly driven by the engine, and uses the characteristics of the motor to generate strong power when starting. fuel consumption. [0005] A...
