Go out gear 8.
Electronic reverse mode is the car-backing function that vehicle is realized using the first dynamotor 51, and in vehicle electromotive inverted is in
During gear pattern, the first dynamotor 51 is as power source and by motor power axle synchronized 33c to motor power axle first
The synchronization of gear 31 and cause the first dynamotor 51 produce power export from motor power axle first gear 31, realize down
Car.
Specifically, with reference to the embodiment of Fig. 6, motor power axle synchronized 33c engagement motor power axles first gear 31, the

Go out.
Specifically, as shown in fig. 6, when power-driven system 100 is in mixed dynamic reverse mode, combining above-mentioned machinery and falling
Gear pattern and electronic reverse mode, engine 4 exports power from reverse output gear 8 according to above-mentioned mechanical reverse mode,
First dynamotor 51 exports power from motor power axle first gear 31 according to above-mentioned electronic reverse mode, and two parts are moved
Power is exported to wheel jointly after coupling at main reducing gear driven gear 74, realizes mixed dynamic reversing.
Now, the first dynamotor 51 can carry out speed governing so that main reducing gear driven gear 74 can be evenly same
Step receives the power from the dynamotor 51 of engine 4 and first, improves ride comfort, the harmony of transmission.
In short, under the mixed dynamic model formula, as shown in fig. 6, motor power axle synchronized 33c engagement motor power the first teeth of axle
Wheel 31 and reverse gear synchronizer 4c engages reverse output gear 8.
Thus, the power-driven system 100 can realize three kinds of reverse modes, i.e., mechanical reverse mode, the electronic mould that reverses gear
Formula and mixed dynamic reverse mode, enrich operating mode of reversing gear, and flexibly can be carried out in three kinds of reverse modes according to actual conditions
Switching, meets driving demand.
For example, in the case of Vehicular battery carrying capacity abundance, electronic reverse mode can be adopted, so in reversing not
Only will not discharge of noxious gases, and can also reducing energy consumption, move backward for position especially for new hand driver, it may be necessary to grasp
Work could repeatedly pour vehicle into specified location, and engine 4 due to producing more pernicious gas in low-reverse, together
When engine 4 be typically in non-economy rotary speed area in reversing, oil consumption is of a relatively high, now adopts the electronic reverse mode can be with
Improve this problem well, discharge can not only be reduced, while realize that low-reverse energy consumption is relatively low as power using motor,
There is certain improvement to the fuel economy of engine 4.
And for example, in the case where Vehicular battery carrying capacity is inadequate or relatively low, can be using mechanical reverse mode.For another example,
Need quickly to move backward or the operating mode such as need high-power to move backward under, then the dynamic of vehicle can be increased using mixed dynamic reverse mode
Power, convenient reversing.
Certainly, the above-mentioned description with regard to three kinds of reverse mode applied environments is only illustrative, it is impossible to be not understood as to this
A kind of restriction of utility model or hint must adopt above-mentioned corresponding reverse mode in the case where vehicle is in above-mentioned environment.For this
For the those of ordinary skill in field, it is clear that can as needed or actual conditions specifically to set corresponding reversing environment under it is required
Reverse mode.
Thus, the reverse mode of power-driven system 100 is further enriched, is more selected to driver, fully carried
