Abstract

A two-gear and dual-motor driven hybrid power transmission device and a transmission method therefore are provided, belonging to the technical field of transmissions. An input end of an input shaft is connected to an engine power system, and an output end of the input shaft is connected to a front-end motor by means of a front-row planetary gear train. The front-row planetary gear train is connected to one end of a first clutch, another end of the first clutch is connected to an input end of an output shaft, and an output end of the output shaft is connected to a rear axle of a vehicle. The output shaft is connected to a rear-end motor by means of a rear-row planetary gear train, and the rear-row planetary gear train is connected to a second clutch and a third clutch.
