According to some typical conditions of the power-driven system 100 of 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 motor power axle second gear 32 linkage described one of gear driven gear, and pass through motor Power axle synchronized 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, the embodiment with reference to shown in Fig. 2, engine 4 can be by power by double clutches after vehicle parking Device 2d and export to the second input shaft 12, motor power axle synchronized 33c engagement motor power axles second gear 32, so as to Jing 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 synchronized 33c, motor power axle 3, the 3rd gear of motor power axle 33rd, export 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.

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., under two clutch whole engagement states of double clutch 2d, (input 23d simultaneously engages with the first output 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 22) output driving vehicle is travelled second output shaft, and another part power is then exported to the first dynamotor 51, and motor is sent out Electricity, enriches transmission mode, takes into account vehicle traveling and charging requirement.

Reverse mode is described again, especially, machinery is had according to the power-driven system 100 of the utility model embodiment 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, engine 4 as power source by the power of generation by a gear driving gear 1a, export after intermediate idler 81 to reversing gear Output gear 8.

Specifically, the embodiment with reference to shown in Fig. 1, six gear synchronized 6c engagement reverse output gears 8, so as to engine 4 power for producing are exported to reverse output gear 8 after keeping off driving gear 1a, intermediate idler 81 by the first input shaft 11, this Conjugation of the sample by reverse gear synchronizer 6c so that the power that reverses gear finally can 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 5c 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, is in electromotive inverted in vehicle 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. 2, motor power axle synchronized 33c engagement motor power axles first gear 31, the First motor gears of power Jing 511, idler gear 512 of the output of one dynamotor 51, the 3rd gear 33 of motor power axle, electricity Export from motor power axle first gear 31 after mechanomotive force axle 3, motor power axle synchronized 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 synchronized 33c engagement motor power axle first gears 31。

Mixed dynamic reverse mode be while the car-backing function of vehicle is realized using engine 4 and the first dynamotor 51, it 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 for producing is kept off actively to one by engine 4 as power source Gear 1a, and the power that engine 4 is produced is caused from the output gear that reverses gear by reverse gear synchronizer synchronization reverse output gear 8 Wheel 8 is exported.

At the same time, the first dynamotor 51 as power source and by motor power axle synchronized 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 Power is exported from reverse output gear 8 by gear pattern and electronic reverse mode, engine 4 according to above-mentioned mechanical reverse mode, Power is exported from motor power axle first gear 31 by the first dynamotor 51 according to above-mentioned electronic reverse mode, and two parts are moved Power is exported after coupling at main reducing gear driven gear 74 jointly to wheel, 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 is received from engine 4 and the power of the first dynamotor 51, improves ride comfort, the harmony of transmission.

In short, under the mixed dynamic model formula, as shown in figure 1, motor power axle synchronized 33c engagement motor power the first teeth of axle Wheel 31 and reverse gear synchronizer 5c 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 repeatedly could pour vehicle into specified location, and engine 4 as more pernicious gas can be produced 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 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, Needing quickly to move backward or needing under the operating modes such as high-power reversing, then the dynamic of vehicle can increased using mixed dynamic reverse mode Power, it is convenient to move backward.
