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.
It is same that some typical conditions of power-driven system 100 according to embodiments of the present invention include power generation in parking, double clutch 2d When engagement in 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 will be caused Power output passes through motor power to the one of gear driven gear to be linked with motor power axle second gear 32 Synchronizations of the axle synchronizer 33c to motor power axle second gear 32 and cause power output to the first dynamotor to drive the One dynamotor is generated electricity.
Specifically, power can be passed through double clutch by the embodiment with reference to shown in Fig. 4, engine 4 after vehicle parking 2d and export to the second input shaft 12, motor power axle synchronizer 33c engagement motor power axles second gear 32, so as to pass through The power of second input shaft 12 can pass through second gear pair, jackshaft first gear 711, jackshaft 71, jackshaft second Gear 712, motor power axle second gear 32, motor power axle synchronizer 33c, motor power axle 3, motor power axle Exported after three gears 33, idler gear 512, the first motor gear 511 to the first dynamotor 51, so as to drive first Dynamotor 51 is generated electricity as generator.
Hereby it is achieved that power generation in parking function, enriches charge mode, and vehicle remains static under power generation in parking operating mode, 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, the energy of engine 4 in the case of description double clutch 2d is simultaneously engaged with Enough a portion is 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. 4, 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 gears Gear pair, five gear gear pairs or seven gear gear pair outputs, another part power of engine 4 can be from the second input shaft 12, two Exported after gear gear pair, motor power axle second gear 32 to the first dynamotor 51, so as to drive the first dynamoelectric and power generation Machine 51 generates electricity.
Because in power drive system of the tradition with double clutch 2d, double clutch 2d only has a clutch in synchronization Device is in running order, and power-driven system 100 according to embodiments of the present invention is realized to the breakthrough of double clutch 2d Using that is, (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 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 Generate electricity, enrich transmission mode, take into account vehicle traveling and charging requirement.
Reverse mode is described again, especially, there is power-driven system 100 according to embodiments of the present invention machinery to reverse gear mould Three kinds of formula, 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, and mechanical reverse mode is in vehicle When, caused power is passed through a gear driving gear 1a, a gear driven gear 1b (duplicate gear) by engine 4 as power source After export to reverse output gear 8.
Specifically, the embodiment with reference to shown in Fig. 4, 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) is exported afterwards To reverse output gear 8, so pass through reverse gear synchronizer 6c conjugation so that the power that reverses gear finally can be from the second output Axle 22 exports.
In short, when vehicle is in mechanical reverse mode, the output as shown in figure 4, only reverse gear synchronizer 6c engagements are reversed gear 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 the electronic mould that reverses gear is in vehicle During formula, the first dynamotor 51 is as power source and by motor power axle synchronizer 33c to motor power axle first gear 31 synchronization and cause power caused by the first dynamotor 51 exported from motor power axle first gear 31, realize reversing.
Specifically, with reference to Fig. 4 embodiment, motor power axle synchronizer 33c engages motor power axle first gear 31, the One dynamotor 51 output power through the first motor gear 511, idler gear 512, the gear 33 of motor power axle the 3rd, Exported after motor power 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 the first electronic hair The path of directly reversing gear of motor 51.
In short, under the electronic reverse mode, only motor power axle synchronizer 33c engagement motor power axles first gear 31.
Mixed dynamic reverse mode is the car-backing function for realizing vehicle using the dynamotor 51 of engine 4 and first simultaneously, mixes and moves Gear pattern is the combination of above-mentioned mechanical reverse mode and electronic reverse mode.
When vehicle is in mixed dynamic reverse mode, caused power output to one is kept off driven gear by engine 4 as power source 1b (duplicate gear), and by reverse gear synchronizer synchronization reverse output gear 8 and power caused by engine 4 falls from this Gear 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 power axle The synchronization of first gear 31 and cause power caused by the first dynamotor 51 exported from motor power axle first gear 31.
Specifically, as shown in figure 4, 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, two parts 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 synchronous The power from the dynamotor 51 of engine 4 and first is received, improves ride comfort, the harmony of transmission.
In short, under the mixed dynamic model formula, as shown in figure 4, 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, electronic reverse mode And mixed dynamic reverse mode, operating mode of reversing gear is enriched, can flexibly be cut according to actual conditions in three kinds of reverse modes Change, meet 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, Engine 4 is typically in non-economy rotary speed area in reversing simultaneously, and oil consumption is of a relatively high, now using electronic reverse mode This problem can be improved well, discharge can not only be reduced, while low-reverse energy consumption is realized as power using motor It is relatively low, 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, exist Need quickly to move backward or need under the operating modes such as high-power reversing, then can use mixed dynamic reverse mode, increase the power of vehicle Property, 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 the present invention A kind of limitation or imply above-mentioned corresponding reverse mode must be used in the case where vehicle be in above-mentioned environment.For the general of this area For logical technical staff, it is clear that can as needed or actual conditions specific to set the mould that reverses gear required under corresponding reversing environment Formula.
Thus, the reverse mode of power-driven system 100 is further enriched, is more selected to driver, is fully improved Driving, preferably meet the requirement of reversing gear of different road conditions.
