Abstract

An electromechanical power coupling device for a hybrid vehicle comprises an engine, a power transmission mechanism, a power output mechanism and an electric mechanism, wherein the engine is connected with both the power output mechanism and the electric mechanism through the power transmission mechanism, the electric mechanism is connected with the power output mechanism through the power transmission mechanism, and the electromechanical power coupling device can operate in different transmission working modes by controlling the engine and the electric mechanism. According to the electromechanical power coupling device, the engine, a power generator and an electromotor are reasonably configured by utilizing a planetary gear mechanism, and the whole power system can realize the function of stepless speed change, so that the overall oil consumption of the hybrid vehicle is better improved.

Description

technical field [0001] The invention relates to an automobile power component, in particular to a planetary gear electromechanical power coupling device for a hybrid electric automobile. Background technique [0002] Energy saving and environmental protection are the focus of automobile technology development in the 21st century. Electric vehicles (EVs) are capable of achieving zero emissions and are the ideal replacement for traditional internal combustion engine vehicles. However, the problems of power battery such as energy density, charging time, price, and lifespan have not been ideally solved, which limits the development of pure electric vehicles. Hybrid electric vehicle (HEV), as a transitional solution for the development of pure electric vehicles, has both the advantages of high specific energy of traditional vehicles and the advantages of low emissions of electric vehicles, and is currently the most practical new energy vehicle. [0003] The main problem solved ...
