Problems solved by technology

The structure of the parallel shaft type is simple, but its structure size is limited by the number of gears, and the transmission is easily interrupted when changing gears, resulting in poor stability and comfort of hybrid vehicles
The planetary gear structure has particularly high requirements for the assembly of gears, as well as high requirements for materials and processing, so the cost of the power transmission system of hybrid electric vehicles is relatively high

Abstract

The invention discloses a two-gear differential coupling hybrid power transmission system with a P3 structure. The system comprises an engine power input mechanism, a first motor power input mechanism, a second motor power input mechanism, a power coupling mechanism and a power output mechanism; two gears can be switched; the system has seven working modes, namely an engine independent driving mode, a single-motor driving mode, a double-motor driving mode, an engine and driving motor hybrid driving mode, a traveling charging mode, an idling charging mode and a braking energy recovery mode. Byadjusting the rotating speed of the first motor, the engine can work in the optimal economic area all the time, and multiple working modes can be switched according to road conditions and the like; the first motor and the engine are coaxially arranged, and the differential coupling transmission mechanism adopts a bevel gear structure, so that the transmission system structure is more compact; thesystem is low in oil consumption, high in power and multiple in modes, the fuel economy of the automobile is improved, and emission performance is optimized.

Description

technical field [0001] The invention belongs to the field of hybrid electric vehicles, and in particular relates to a power coupling transmission system of a hybrid electric vehicle. Background technique [0002] At present, the power transmission system of a hybrid electric vehicle is mainly divided into a parallel shaft structure and a planetary wheel structure. The structure of the parallel shaft type is simple, but its structure size is limited by the number of gears, and the transmission is easily interrupted when shifting gears, resulting in poor stability and comfort of the hybrid vehicle. The planetary gear structure has particularly high requirements for the assembly of gears, as well as high requirements for materials and processing, so the cost of the power transmission system of hybrid electric vehicles is relatively high. Contents of the invention [0003] In order to realize simple structure, good technology and multi-mode operation, the present invention pr...
