Abstract

The invention discloses a multimode power transmission system of a hybrid electric vehicle. A motor input gear is fixedly connected to a motor input shaft, an electric generator input gear is fixedlyconnected to an electric generator input shaft, an engine input gear is fixedly connected to an engine, the engine input gear is engaged with the electric generator input gear, and a reducer gear is fixedly connected to a main reducer, a duplicate gear engaged with the motor input gear is arranged on an engine input shaft in an empty sleeving mode, and an electric generator gear set which is engaged with the reducer gear is connected to the electric generator input shaft, and power is transmitted between the duplicate gear and the reducer gear through a high-low gear switching mechanism of a synchronizer. Through empty sleeving and coaxial mounting arrangement of the gears, the size is reduced, through cooperated working of the engine and the motor in various working conditions, both the engine and a driving motor can work in a high efficiency interval.

Description

technical field [0001] The invention relates to the technical field of transmission structure of a hybrid electric vehicle, in particular to a multi-mode power transmission system of a hybrid electric vehicle. Background technique [0002] Energy saving and environmental protection have become the two major themes in the development of automobile technology. In recent years, hybrid electric vehicles that reduce fuel consumption and emissions have been developed and applied, and have developed rapidly in the process of commercialization and industrialization. At present, hybrid electric vehicles that have been mass-produced Cars include Toyota Prius, Mitsubishi Outlander PHEV, BYD Qin and so on. [0003] At present, there are many schemes for automobile hybrid power devices, each of which has advantages and disadvantages. For example, the "Powertrain for Hybrid Vehicles" (Chinese Patent No. CN205439956U) of Shanghai Natiefu Transmission Co., Ltd. is a dual-motor multi-mode s...
