Abstract

The invention discloses a multimode power transmission structure of a hybrid electric vehicle. A first clutch is connected between a motor input shaft and an engine input shaft; an engine input gear is fixedly connected to the engine input shaft, a reducer gear is fixedly connected to a main reducer, a first-gear driving gear and a second-gear driving gear are fixedly connected to the motor inputshaft, the first-gear driving gear and the second-gear driving gear transmits power to the reducer gear through an engine output gear set, and an engine input gear transmits power to the reducer gearthrough an engine output gear set. The mass of a power assembly and cost of the power assembly are reduced by canceling an electric generator; both the engine and the electric generator can work in ahigh efficiency interval; the ability of starting, accelerating and climbing a slope of the vehicle is improved, and the maximum rotating speed of a motor is reduced, so that cost of the motor is reduced; no power interrupt occurs on the engine and the motor in the gear shifting process; and the transmission device is small in size, compact in whole structure, and convenient to arrange.

Description

technical field [0001] The invention relates to the technical field of a transmission structure of a hybrid electric vehicle, in particular to a multi-mode power transmission structure 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] From the perspective of power coupling, hybrid electric vehicles mainly include parallel, series and hybrid. [0004] At present, there are many schemes for automobile hybrid power devices, each of which has advantages and disadvantages. For example, the "Powertrain fo...
