Power does not interrupt when guarantee system is shifted gears, and promotes the comfort of driving.
The course of work of first embodiment of the invention is simply illustrated below:
When automobile, which is in, reverses gear pure electric vehicle drive mode, the engine 2 is without power transmission.The main drive motor 9
Start and invert, power transmission line is as follows: 9-E of main drive motor mono- keeps off 91-E of driving gear mono- and keeps off driven gear 81-
Third 8-third of output shaft connected toothed wheel 84 --- the final gear 101 of differential mechanism 100 completes power transmission.
When automobile is in pure electric vehicle drive mode, the engine 2 is without power transmission.The main drive motor 9
Starting, power transmission line are as follows: it is defeated that 9-E of main drive motor mono- keeps off the gear 81-third of driven gear of 91-E of driving gear mono-
The final gear 101 of 8-third of shaft connected toothed wheel 84 --- differential mechanism 100 completes power transmission.
When automobile is in a gear hybrid power drive mode, the stand-by motor 4 pre-actuates the engine 2, and
By its it is counter be dragged to high-efficiency and economic area, at this point, the clutch 3 is closed, power transmission line is as follows: engine 2-bis- quality
Flywheel 21-1-stand-by motor of solid input shaft, 4-clutch 3-51-D of the 1-the first duplicate gear of solid input shaft mono- gear from
The final gear of 61-D of moving gear, mono- or two 64-differential mechanism of synchronizer the 6-the first connected toothed wheel of the 63-the first output shaft 100
101, complete power transmission.Meanwhile in shift process, the main drive motor can start, and supplement power difference guarantees system
Power does not interrupt when shift, promotes the comfort of driving, and power transmission line is as follows: 9-E of main drive motor mono- keeps off driving tooth
It takes turns 91-E mono- and keeps off 81-third of driven gear, 8-third of output shaft connected toothed wheel 84 --- the final gear of differential mechanism 100
101, complete power transmission.
When automobile is in second gear, three gear hybrid power drive modes, power transmission line is kept off with when automobile is in one
Power transmission line is identical when hybrid power drive mode, does not just do and excessively repeats.In the present invention, the arrangement of gear is this hair
One embodiment in bright, in order to understand.Certainly, it can also arrange for other modes, other modes arrangement is in the present invention
Protection category therefore do not do and excessively repeat.In addition, as needed, the parking gear 31 also can be set in the first output
The driven gear of two gears is set on axis 6, on corresponding second output shaft 7.
As shown in Fig. 2, being the second embodiment of the present invention, compared with first embodiment, distinctive points are the E gear set
The specific structure of part, specifically, the E gear assembly includes the gear active of E mono- being installed on 9 motor shaft of main drive motor

Space in transmission housing body, main drive motor can be designed to larger size, to improve the power of stand-by motor, in pure electric vehicle
There is down preferable power performance；
4, when vehicle launch, clutch is in discrete state, is driven with main drive motor, and driving vehicle to engine can be
When the speed of high-efficiency and economic area work, stand-by motor pre-actuates engine and it is made to intervene drive in high-efficiency and economic area speed
It is dynamic, it realizes that in parallel mix is moved, and gradually main drive motor can be replaced to drive, oil consumption can be greatly reduced, greatly save cost；
5, main drive motor supplement power difference guarantees that power does not interrupt when system shift during engine gear, and promotion is driven
The comfort sailed；
6, traditional reverse gear is removed, can be realized and reverses gear by main drive motor reversing；
7, in the case where main drive motor works independently, as battery pack electricity is lower than certain setting value, stand-by motor starting
Engine, engine start to efficient economic zone directly drive active motor by stand-by motor power generation or charge for battery pack,
When start under dead ship condition for battery pack supplement electricity；
8, it when vehicle braking, is recovered energy, is avoided energy waste by main drive motor；
9, engine can work on random shift, realize large range of intervention, suitable for more complicated operating conditions；
10, for stand-by motor when engine parallel connection interventional systems work, can produce load makes engine approach high school district work as far as possible
Make, and the load generated can be used for generating electricity, it is more energy efficient；
11, second embodiment and fourth embodiment can have the selection of two gears in pure electric vehicle operating condition downward driving, gear, can be as needed
Gear switching is carried out, to reduce the requirement to main drive motor.In addition, this system, in monomotor operating condition downward driving, E is synchronous
Device is not put into gear, and main drive motor will not be " dragged ", and main drive motor rotor would not rotate, will not generate rotary inertia, and
Shift will not be had an impact, eliminate impact sense, vehicle not will shake, and ride comfort is preferable；
12, this system is more compact, light-weight, small in size, is conducive to vehicle carrying.Although should be appreciated that this specification according to reality
The mode of applying is described, and every embodiment includes only a single technical solution, this narration side of specification
