When the vehicle underload travels and storage battery energy when being lower than a threshold value the first electric motor starting driving engine.Driving engine is work in a single day, and first motor just forwards generating state rapidly to from motoring condition, drives first electric power generation by driving engine and give the car load battery charge, and engaging and disengaging gear still disconnects.At this moment, driving engine drives first electric power generation and charges a battery, and storage battery provides electric energy to second motor, so just realizes motivity, first motor, storage battery, the tandem drive of the whole hybrid power of second motor.In this process, first motor comes start the engine work in early stage as electrical motor, and the later stage uses as electrical generator, and second motor uses as electrical motor.
When vehicle at a high speed or climbing when travelling, the second motor horsepower output deficiency, the control engaging and disengaging gear makes motor shaft one be connected with motor shaft two, the output shaft of driving engine drives motor shaft one and motor shaft two rotates synchronously, the power that driving engine produces is direct drive vehicle ' or power distribution travelled to generator for electricity generation and powered vehicle all, satisfies the demand of vehicle different capacity.
In above-mentioned hybrid electric drive system, described engaging and disengaging gear is a power-transfer clutch.
During disengaging of clutch, the power storage of first motor output is supplied with the second motor electric energy by storage battery in storage battery.Motor shaft one is on the same axle center with motor shaft two, and during the power-transfer clutch adhesive, motor shaft one is connected synchronously with motor shaft two and rotates driving engine, first motor and the second motor three synchronous working.
In above-mentioned hybrid electric drive system, described first motor is identical with second motor.First motor is identical with second motor and can realize mutual conversion, and both power is identical.During first electric power generation, the second motor-driven motor shaft two rotates.
In above-mentioned hybrid electric drive system, described power-transfer clutch comprises driving link and the driven member that installs relatively, and described driving link is connected with motor shaft one, and driven member is connected with motor shaft two.
Compared with prior art, the engine drive motor shaft one of this hybrid electric drive system rotates, and comes control vehicle to travel, and utilize separation and reunion between motor shaft one and the motor shaft two, and can realize engine power is distributed, simple in structure, be easy to realize, can realize industrialization.
