Similarly, motor power axle first gear 31 can be used for power of the output through motor power axle 3, therefore motor power Axle first gear 31 equally with the engaged transmission of main reducing gear driven gear 74.

Some typical conditions of power-driven system 100 according to embodiments of the present invention include power generation in parking, double clutch 2d simultaneously engage with the case of the charge mode and reverse mode in driving.

Power generation in parking this typical condition is described first, when vehicle is in parked state, engine 4 is arranged to produce Power output to the one of gear driven gear to be linked with motor power axle second gear 32, and pass through motor Synchronizations of the power axle synchronizer 33c to motor power axle second gear 32 and cause power output to the first dynamotor to drive First dynamotor is generated electricity.

Specifically, power can be passed through double clutches by the embodiment with reference to shown in Fig. 2, engine 4 after vehicle parking Device 2d and export to the second input shaft 12, motor power axle synchronizer 33c engagement motor power axles second gear 32, so as to through the The power of two input shafts 12 can pass through second gear pair, jackshaft first gear 711, jackshaft 71, jackshaft second gear 712nd, motor power axle second gear 32, motor power axle synchronizer 33c, motor power axle 3, the gear of motor power axle the 3rd 33rd, exported after idler gear 512, the first motor gear 511 to the first dynamotor 51, so as to drive the first dynamotor 51 are generated electricity as generator.

Hereby it is achieved that power generation in parking function, enriches charge mode, and vehicle is in static shape under power generation in parking operating mode State, the power of engine 4 can be completely used for charging, and improve charge efficiency, realize quick function of supplying power.

Secondly charged in driving operating mode, under the operating mode, engine 4 in the case of description double clutch 2d is simultaneously engaged with A portion can be moved by input 23d and conjugation while the first output end 21d and the second output end 22d Power is exported by a wherein output shaft and gives power of the wheel to be travelled as vehicle, and another part power is passed through into motor Power axle second gear 32 is exported to the first dynamotor 51 to drive the first dynamotor 51 to be generated electricity.

Specifically, the embodiment with reference to shown in Fig. 2, under the operating mode, motor power axle synchronizer 33c engagement motor powers Axle second gear 32, a part of power of engine 4 may be output to the first input shaft 11, then pass through first gear pair, three gear teeth Wheel set, five gear gear pairs or seven gear gear pair outputs, another part power of engine 4 can keep off tooth from the second input shaft 12, two Exported after wheel set, motor power axle second gear 32 to the first dynamotor 51, so as to drive the first dynamotor 51 to send out Electricity.

Due to tradition with double clutch 2d power drive system in, double clutch 2d synchronization only have one from Clutch is in running order, and power-driven system 100 according to embodiments of the present invention realizes the breakthrough to double clutch 2d Property application, i.e., (input 23d simultaneously engages with the first output end under double clutch 2d two clutch whole engagement states 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, engine 4 as power source by caused power output to reverse gear shaft 89, and it is defeated synchronously to be reversed gear by reverse gear synchronizer Go out gear 8 and so that power caused by engine 4 exports from the reverse output gear 8.

Specifically, the embodiment with reference to shown in Fig. 2, six gear synchronizer 6c engagement reverse output gears 8, so as to engine Power caused by 4 so passes through reverse gear synchronizer by being exported after the second input shaft 12, reverse gear shaft 89 to reverse output gear 8 6c conjugation so that the power that reverses gear can finally export from the second output shaft 22.

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.

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. 2 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 as power source by caused power output to reverse gear shaft 89, And by reverse gear synchronizer synchronization reverse output gear 8 and power caused by engine 4 is defeated from the reverse output gear 8 Go out.

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 Fig. 2 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 Fig. 2 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 2-Figure 5, second can also be set up Dynamotor 52 enriches transmission mode to increase the dynamic property of power-driven system 100.
