With reference to Fig. 1-Figure 13 to three power output shafts (i.e. the first output shaft 21, the second output shaft 22 and motor power axle 3) and vehicle Annexation between differential mechanism 75 is described in detail.
The differential mechanism 75 of vehicle can be arranged between a pair of front-wheels 76 or between a pair of rear wheels, in some examples of the present invention, differential mechanism 75 It is between a pair of front-wheels 76.The function of differential mechanism 75 is when turn inside diameter is travelled or travelled on uneven road surface, makes left and right driving car Wheel is rolled with different angular speed, to ensure to make PURE ROLLING between two side drive wheels and ground.It is driven that main reducing gear is provided with differential mechanism 75 Gear 74, such as main reducing gear driven gear 74 can be arranged on the housing of differential mechanism 75.Main reducing gear driven gear 74 can be cone tooth Wheel, but not limited to this.

Similarly, the second output shaft output gear 221 is fixedly installed on the second output shaft 22, the second output shaft output gear 221 is defeated with second The synchronous axial system of shaft 22, the second output shaft output gear 221 and the engaged transmission of main reducing gear driven gear 74, so as to through the second output shaft 22 Power can be transferred to main reducing gear driven gear 74 and differential mechanism 75 from the second output shaft output gear 221.
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 engages with situation Under 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 be arranged to by caused power output to One of gear driven gear that motor power axle second gear 32 links, and by motor power axle synchronizer 33c to motor power The synchronization of axle second gear 32 and cause power output to the first dynamotor to drive the first dynamotor to be generated electricity.
Specifically, the embodiment with reference to shown in Figure 12, engine 4 after vehicle parking can by power by double clutch 2d and export to Second input shaft 12, motor power axle synchronizer 33c engagements motor power axle second gear 32, so as to which the power through the second input shaft 12 can be with Pass through second gear pair, jackshaft first gear 711, jackshaft 71, jackshaft second gear 712, motor power axle second gear 32, electricity It is defeated after mechanomotive force axle synchronizer 33c, motor power axle 3, the gear 33 of motor power axle the 3rd, idler gear 512, the first motor gear 511 Go out to the first dynamotor 51, so as to drive the first dynamotor 51 to be 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, engine 4 Power can be completely used for charging, and improve charge efficiency, realize quick function of supplying power.
Secondly the operating mode that charged in driving in the case of description double clutch 2d is simultaneously engaged with, under the operating mode, engine 4 can pass through input Hold 23d and the first output end 21d and the second output end 22d while conjugation and a portion power is defeated by a wherein output shaft Go out to give power of the wheel to be travelled as vehicle, and another part power is exported to the first dynamoelectric and power generation by motor power axle second gear 32 Machine 51 is generated electricity with the first dynamotor 51 of driving.
Specifically, the embodiment with reference to shown in Figure 12, under the operating mode, motor power axle synchronizer 33c engagement motor power axle second gears 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 gear pairs, five gear gear pairs or seven Gear pair output is kept off, another part power of engine 4 can be after the second input shaft 12, second gear pair, motor power axle second gear 32 Export to the first dynamotor 51, so as to drive the first dynamotor 51 to generate electricity.
Because in power drive system of the tradition with double clutch 2d, double clutch 2d only has a clutch to be in work shape in synchronization State, and power-driven system 100 according to embodiments of the present invention realizes the breakthrough application to double clutch 2d, i.e., double clutch 2d's Under two clutch whole engagement states (input 23d simultaneously engages with the first output end 21d and the second output end 22d) so that engine 4 A part of power by an output shaft (such as the first output shaft 21 or second output shaft 22) output driving vehicle travel, another part power Then export and generated electricity to the first dynamotor 51, motor, enrich transmission mode, 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 has mechanical reverse mode, electronic reversed gear Three kinds of reverse modes of pattern and mixed dynamic reverse mode.
Mechanical reverse mode is the car-backing function that vehicle is realized using the power of engine 4, when vehicle is in mechanical reverse mode, engine 4 Caused power is exported to reverse output gear 8 afterwards by two gear driving gear 2a, two gear driven gear 2b (duplicate gear) as power source.
Specifically, the embodiment with reference to shown in Figure 12, six gear synchronizer 6c engagement reverse output gears 8, so as to be moved caused by engine 4 Power is exported to reverse output gear 8 afterwards by the second input shaft 12, two gear driving gear 2a, two gear driven gear 2b (duplicate gear), this The conjugation that sample passes through reverse gear synchronizer 6c 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 figure 12, only reverse gear synchronizer 6c engagement reverse output gears 8.This In the case of kind, 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, when vehicle is in electronic reverse mode, first First electricity as power source and by synchronizations of the motor power axle synchronizer 33c to motor power axle first gear 31 of dynamotor 51 Power caused by dynamic generator 51 exports from motor power axle first gear 31, realizes reversing.
Specifically, with reference to Figure 12 embodiment, motor power axle synchronizer 33c engagement motor power axles first gear 31, the first dynamoelectric and power generation The power that machine 51 exports is through the first motor gear 511, idler gear 512, the gear 33 of motor power axle the 3rd, motor power axle 3, motor Exported after 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 straight of the first dynamotor 51 Connect path of reversing gear.
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, and it is upper to mix dynamic reverse mode State the combination of mechanical reverse mode and electronic reverse mode.
When vehicle is in mixed dynamic reverse mode, caused power output to two is kept off driven gear 2b (duplicate gear) by engine 4 as power source, And by reverse gear synchronizer synchronization reverse output gear 8 and power caused by engine 4 exports from the reverse output gear 8.
At the same time, the first dynamotor 51 is used 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.
Specifically, as shown in figure 12, when power-driven system 100 is in mixed dynamic reverse mode, combine above-mentioned mechanical reverse mode and Electronic reverse mode, engine 4 export power from reverse output gear 8 according to above-mentioned mechanical reverse mode, and the first dynamotor 51 is pressed Power is exported from motor power axle first gear 31 according to above-mentioned electronic reverse mode, two parts power couples at main reducing gear driven gear 74 Export jointly afterwards to wheel, realize mixed dynamic reversing.
Now, the first dynamotor 51 can carry out speed governing so that main reducing gear driven gear 74, which evenly can synchronously receive to come from, to be started The power of the dynamotor 51 of machine 4 and first, improve ride comfort, the harmony of transmission.
In short, under the mixed dynamic model formula, as shown in figure 12, motor power axle synchronizer 33c engages motor power axle first gear 31 and reversed gear Synchronizer 6c engages reverse output gear 8.
Thus, the power-driven system 100 can realize three kinds of reverse modes, i.e., mechanical reverse mode, electronic reverse mode and mixed move are reversed gear Pattern, operating mode of reversing gear is enriched, can flexibly be switched over according to actual conditions in three kinds of reverse modes, meet driving demand.
For example, in the case of Vehicular battery carrying capacity abundance, electronic reverse mode can be used, so will not only be discharged in reversing harmful Gas, and energy consumption can also be reduced, moved backward especially for new hand driver for position, it may be necessary to which operation could repeatedly pour into vehicle specified Position, and engine 4 be due to that can produce more pernicious gas in low-reverse, while engine 4 is typically in non-economy in reversing and turned Fast region, oil consumption is of a relatively high, now can improve this problem well using electronic reverse mode, can not only reduce discharge, adopt simultaneously Realize that low-reverse energy consumption is relatively low by the use of motor as power, have 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, quick reversing is being needed Or need under the operating modes such as high-power reversing, then mixed dynamic reverse mode can be used, increases the dynamic property of vehicle, convenient reversing.
Certainly, the above-mentioned description as described in three kinds of reverse mode application environments is only illustrative, it is impossible to be not understood as a kind of limitation to the present invention or Above-mentioned corresponding reverse mode must be used in the case where vehicle is in above-mentioned environment by implying.For the ordinary skill in the art, it is clear that can be with As needed or actual conditions carry out the specific reverse mode set needed under corresponding reversing environment.
Thus, the reverse mode of power-driven system 100 is further enriched, is more selected to driver, fully improves Driving, more Meet the requirement of reversing gear of different road conditions well.
According to the power-driven system 100 of some embodiments of the present invention, as shown in Fig. 8-Figure 12, the second dynamotor 52 can also be set up To increase the dynamic property of power-driven system 100, transmission mode is enriched.
For example, in wherein some embodiments, the second dynamotor 52 can be driven with main reducing gear driven gear 74, such as the second electronic hair Gear can be set on the motor shaft of motor 52, the gear and 74 direct engaged transmission of main reducing gear driven gear.And for example, implement at other In example, the second dynamotor 52 can also be arranged to the first input shaft 11 be connected or with the first output shaft 21 be connected.For another example, another In a little embodiments, the second dynamotor 52 is two and is separately positioned on the both sides of differential mechanism 75, such as this two the second dynamotor 52 It can become one with differential mechanism 75.Or the foregoing dynamotor 51 of engine 4 and first is used to drive front-wheel, the second electronic hair Motor 52 can also be wheel motor and be used for trailing wheel, or the second dynamotor 52 can drive two trailing wheels by a reducing gear, Or second dynamotor 52 be two and pass through reducing gear respectively to drive a trailing wheel.
