21d and the second output end 22d) so that a part of power of engine 4 is by an output shaft (such as the first output shaft 21 or the
Two output shafts 22) output driving vehicle traveling, another part power then exports to be sent out to the first dynamotor 51, motor
Electricity, transmission mode is enriched, take into account vehicle traveling and charging requirement.
Reverse mode is described again, especially, power-driven system 100 according to embodiments of the present invention reverses gear with machinery
Three kinds of pattern, electronic reverse mode and mixed dynamic reverse mode reverse modes.
Mechanical reverse mode is the car-backing function that vehicle is realized using the power of engine 4, is reversed gear in vehicle in machinery
During pattern, caused power is passed through a gear driving gear 1a, a gear driven gear 1b (duplex-gears by engine 4 as power source
Wheel) export afterwards to reverse output gear 8.
Specifically, the embodiment with reference to shown in Fig. 1, six gear synchronizer 6c engagement reverse output gears 8, so as to engine
Power caused by 4 keeps off driving gear 1a by the second input shaft 12, one, a gear driven gear 1b (duplicate gear) exports to afterwards
Output gear 8 is kept off, so passes through reverse gear synchronizer 6c conjugation so that the power that reverses gear finally can be defeated from the second output shaft 22
Go out.
In short, when vehicle is in mechanical reverse mode, as shown in Fig. 2 only reverse gear synchronizer 6c engagements reverse gear it is defeated
Go out gear 8.In this case, driving-chain is shorter, intermediate transmission part is less, efficiency high of reversing gear.
Electronic reverse mode is the car-backing function that vehicle is realized using the first dynamotor 51, and electromotive inverted is in vehicle
During gear pattern, the first dynamotor 51 is as power source and by motor power axle synchronizer 33c to motor power axle first
The synchronization of gear 31 and cause power caused by the first dynamotor 51 exported from motor power axle first gear 31, realization is fallen
Car.
Specifically, with reference to Fig. 1 embodiment, motor power axle synchronizer 33c engages motor power axle first gear 31, the
The power of one dynamotor 51 output is through the first motor gear 511, idler gear 512, the gear 33 of motor power axle the 3rd, electricity
Exported after mechanomotive force axle 3, motor power axle synchronizer 33c from motor power axle first gear 31.
In this case, driving-chain is shorter, intermediate transmission part is less, efficiency high of reversing gear, it is believed that is first electronic
The path of directly reversing gear of generator 51.
In short, under the electronic reverse mode, only motor power axle synchronizer 33c engagement motor power axle first gears
31。
Mixed dynamic reverse mode is the car-backing function for realizing vehicle using the dynamotor 51 of engine 4 and first simultaneously, is mixed
Dynamic reverse mode is the combination of above-mentioned mechanical reverse mode and electronic reverse mode.
When vehicle is in mixed dynamic reverse mode, engine 4 is driven to a gear by caused power output as power source
Gear 1b (duplicate gear), and by reverse gear synchronizer synchronization reverse output gear 8 and power caused by engine 4 from this
Reverse output gear 8 exports.
At the same time, the first dynamotor 51 is used as power source and by motor power axle synchronizer 33c to motor
The synchronization of power axle first gear 31 and cause power caused by the first dynamotor 51 it is defeated from motor power axle first gear 31
Go out.
Specifically, as shown in figure 1, when power-driven system 100 is in mixed dynamic reverse mode, combine above-mentioned machinery and fall
Gear pattern and electronic reverse mode, engine 4 export 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 move
Power exports to wheel jointly after being coupled 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 figure 1, motor power axle synchronizer 33c engages motor power the first tooth of axle
Take turns 31 and reverse gear synchronizer 6c engagement reverse output gears 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, can flexibly be carried out according to actual conditions in three kinds of reverse modes
Switching, meets driving demand.
For example, in the case of Vehicular battery carrying capacity abundance, electronic reverse mode can be used, so in reversing not
Only will not discharge of noxious gases, and energy consumption can also be reduced, be moved backward especially for new hand driver for position, it may be necessary to grasp
Work could repeatedly pour into vehicle specified location, and engine 4 be due to that can produce 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 uses 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, mechanical reverse mode can be used.For another example,
In the case where needing quickly to move backward or needing the operating modes such as high-power reversing, then mixed dynamic reverse mode can be used, increase moving for vehicle
Power, convenient reversing.
Certainly, the above-mentioned description as described in three kinds of reverse mode application environments is only illustrative, it is impossible to is not understood as to this
A kind of limitation of invention or hint must use above-mentioned corresponding reverse mode in the case where vehicle is in above-mentioned environment.For this area
Those of ordinary skill for, it is clear that can as needed or actual conditions specific to set falling needed under corresponding reversing environment
Gear pattern.
Thus, the reverse mode of power-driven system 100 is further enriched, more selects to driver, fully carries
High Driving, preferably meet the requirement of reversing gear of different road conditions.
According to the power-driven system 100 of some embodiments of the present invention, as Figure 1-Figure 8, second can also be set up
Dynamotor 52 enriches transmission mode to increase the dynamic property of power-driven system 100.
For example, in wherein some embodiments, the second dynamotor 52 can be driven with main reducing gear driven gear 74, example
Gear such as can be set on the motor shaft of the second dynamotor 52, the gear directly engages biography with main reducing gear driven gear 74
It is dynamic.And for example, in further embodiments, the second dynamotor 52 can also be arranged to be connected with the first input shaft 11 or with
One output shaft 21 is connected.For another example, in still other embodiments, the second dynamotor 52 is two and is separately positioned on differential mechanism
75 both sides, such as this two the second dynamotor 52 can become one with differential mechanism 75.Or foregoing engine
4 and first dynamotor 51 be used for drive front-wheel, the second dynamotor 52 can also be wheel motor and be used for trailing wheel, or
The second dynamotor of person 52 can drive two trailing wheels by a reducing gear, or the second dynamotor 52 is two
And a trailing wheel is driven by a reducing gear respectively.
