Some typical conditions of power-driven system 100 according to the utility model embodiment include power generation in parking, it is double from Clutch 2d simultaneously engage with the case of the charge mode and reverse mode when 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 described one of gear driven gear linked with motor power axle second gear 32, and by motor Power axle synchronizer 33c causes power output to the first dynamotor to drive the synchronization of motor power axle second gear 32 First dynamotor is generated electricity.

Specifically, power can be passed through double clutches by the embodiment with reference to shown in Fig. 1, 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 be by 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 to the first dynamotor 51 after idler gear 512, the first motor gear 511, so as to drive the first dynamotor 51 are generated electricity as generator.

Hereby it is achieved that power generation in parking function, vehicle is in static shape under enriching charge mode, and 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 the charging operating mode when driving in the case of description double clutch 2d is simultaneously engaged with, under the operating mode, engine 4 Can by input 23d with the first output end 21d and the second output end 22d while conjugation and a portion is moved Power exports the power travelled as vehicle to wheel by wherein one output shaft, 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. 1, 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 by 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 to the first dynamotor 51 after wheel set, motor power axle second gear 32, 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 one of which from Clutch is in running order, and is realized to double clutch 2d's according to the power-driven system 100 of the utility model embodiment Breakthrough application, i.e., (input 23d simultaneously engages with the first output under two clutches whole engagement state of double clutch 2d End 21d and the second output end 22d) so that a part of power of engine 4 by an output shaft (such as the first output shaft 21 or Second output shaft 22) output driving vehicle traveling, another part power then exported to the first dynamotor 51, motor hair Electricity, enriches transmission mode, takes into account vehicle traveling and charging requirement.

Reverse mode is described again, especially, the power-driven system 100 according to the utility model embodiment has machinery Reverse mode, three kinds of reverse modes of electronic reverse mode and mixed dynamic reverse mode.

Mechanical reverse mode is the car-backing function that vehicle is realized using the power of engine 4, is reversed gear in machinery in vehicle During pattern, to reverse gear shaft 89, and it is defeated synchronously to be reversed gear by reverse gear synchronizer for the power output that engine 4 will be produced as power source Go out gear 8 and so that the power that engine 4 is produced is exported from the reverse output gear 8.

Specifically, the embodiment with reference to shown in Fig. 1, six gear synchronizer 6c engagement reverse output gears 8, so that engine 4 power for producing after the first input shaft 11, reverse gear shaft 89 by exporting to reverse output gear 8, so by reverse gear synchronizer The conjugation of 6c so that the power that reverses gear can finally be exported from the second output shaft 22.

In short, when vehicle is in mechanical reverse mode, as shown in figure 1, 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 the first dynamotor 51 produce power exported from motor power axle first gear 31, realize down Car.

Specifically, with reference to the embodiment of Fig. 2, motor power axle synchronizer 33c engagement motor power axles first gear 31, the The power of the output of one dynamotor 51 is through the first motor gear 511, idler gear 512, the gear 33 of motor power axle the 3rd, electricity Exported from motor power axle first gear 31 after mechanomotive force axle 3, motor power axle synchronizer 33c.

In this case, driving-chain is shorter, intermediate transmission part is less, efficiency high of reversing gear, it is believed that be 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, the power output that engine 4 will be produced as power source to reverse gear shaft 89, And cause that the power that engine 4 is produced is defeated from the reverse output gear 8 by reverse gear synchronizer synchronization reverse output gear 8 Go out.

At the same time, the first dynamotor 51 is as power source and passes through motor power axle synchronizer 33c to motor The synchronization of power axle first gear 31 and cause the first dynamotor 51 produce power 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, combining above-mentioned machinery and falling 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 are moved Power is exported 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 engagement motor power the first teeth of axle Wheel 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, and can flexibly 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 used, so in reversing not Only will not discharge of noxious gases, and can also reducing energy consumption, moveed backward for position especially for new hand driver, it may be necessary to grasp Vehicle could repeatedly be poured into specified location, and engine 4 due to that can produce more pernicious gas in low-reverse by work, together When engine 4 be typically in non-economy rotary speed area in reversing, oil consumption is of a relatively high, now uses 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 it is quick 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 on three kinds of reverse mode applied environments is only illustrative, it is impossible to be not understood as to this A kind of limitation of utility model or hint must use 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 are required under corresponding reversing environment specifically to set Reverse mode.

Thus, the reverse mode of power-driven system 100 is further enriched, is more selected to driver, fully carried Driving high, preferably meets the requirement of reversing gear of different road conditions.

Power-driven system 100 according to some embodiments of the present utility model, as Figure 1-Figure 8, can also set up Second dynamotor 52 enriches transmission mode to increase the dynamic property of power-driven system 100.

For example, wherein in some embodiments, the second dynamotor 52 can be driven with main reducing gear driven gear 74, example As that can set gear 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 to driving the 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 respectively by reducing gear one trailing wheel of driving.
