Comprise power generation in parking, double clutch 2d together according to some typical conditions of the power drive system 100 of the embodiment of the present inventionTime limit driving limit charge mode and the pattern of reversing gear in joint situation.

First describe this typical condition of power generation in parking, at vehicle during in parking state, engine 4 is arranged to producePower exports the first dynamotor 51 to by motor mechanical axis the first gear 31, thereby drives the first dynamotor 51Generate electricity.

Particularly, in conjunction with the embodiment shown in Fig. 1-Fig. 5, engine 4 after vehicle parking can by power by two fromClose device 2d and export to the second power shaft 12,4a is middle lazy by first for the gear of four on this second power shaft 12 driving gearWheel 731 links with motor mechanical axis the first gear 31 on motor mechanical axis 3, controls motor mechanical axis the first synchronized33c engages motor mechanical axis 3 and motor mechanical axis the first gear 31, and the power that engine 4 is exported will be from the second power shaft12, in the middle of four gear driving gear 4a, first, idle pulley 731, motor mechanical axis the first gear 31 and motor mechanical axis first are synchronousDevice 33c exports motor mechanical axis 3 to, and finally this part power is exported to the first dynamotor 51 from motor mechanical axis 3,Thereby drive the first dynamotor 51 to generate electricity as generator.

Thus, has realized power generation in parking function, enriched charge mode, and under power generation in parking operating mode, vehicle remains static,The power of engine 4 can, all for charging, improve charge efficiency, realizes quick function of supplying power.

Certainly, be understandable that, at vehicle, during in parking state, engine 4 can also output power to the first inputAxle 11, and by power is defeated after the first motor gear 71, the second middle idle pulley 732, motor mechanical axis the second gear 32Go out to the first dynamotor 51, thereby drive the first dynamotor 51 to generate electricity. In brief, at this bang pathUnder, engine 4 is arranged to export the power of generation to first dynamotor 51 by motor mechanical axis the second gear 32To drive the first dynamotor 51 to generate electricity, now motor mechanical axis the first synchronized 33c engages motor mechanical axis 3 HesMotor mechanical axis the second gear 32.

Secondly double clutch 2d driving limit, limit charging operating mode in joint situation is simultaneously described, under this operating mode, engine 4 energyEnough by input 23d and the first output 21d and the second output 22d time, conjugation will be wherein a part of movingPower is exported to wheel using the power as Vehicle Driving Cycle by an output shaft wherein, and another part power is passed through to motorMechanical axis the first gear 31 or motor mechanical axis the second gear 32 are exported to the first dynamotor 51, thereby driving first is electronicGenerator 51 generates electricity.

Particularly, in conjunction with the specific embodiment of Fig. 1-Fig. 5 example, first with electric by the first gear 31 outputs of motor mechanical axisMachine charging power is example. Under this operating mode, exportable first power shaft 11 of giving of a part of power of engine 4, then by a gearGear pair, three gear gear pairs or five gear gear pairs outputs, another part power of engine 4 can be from the second power shaft 12, fourIdle pulley 731 in the middle of gear driving gear 4a, first, motor mechanical axis the first gear 31, motor mechanical axis the first synchronized 33c,The first dynamotor 51 is exported in motor mechanical axis 3 these paths, thereby drives the first dynamotor 51 to generate electricity.

Again to charge power as example by motor mechanical axis the second gear 32 output motors. Under this operating mode, of engine 4Exportable second power shaft 12 of giving of sub-power, the more secondary or four gear gear pair outputs by second gear, another portion of engine 4Sub-power can from idle pulley 732 in the middle of the first power shaft 11, the first motor gear 71, second, motor mechanical axis the second gear 32,The first dynamotor 51 is exported in motor mechanical axis the first synchronized 33c, motor mechanical axis 3 these paths, thereby drivesThe first dynamotor 51 generates electricity

Because tradition has in the power drive system of double clutch 2d, double clutch 2d only has a clutch at synchronizationDevice is in running order, and has realized breakthrough to double clutch 2d according to the power drive system 100 of the embodiment of the present inventionApplication, under two whole engagement states of clutch of double clutch 2d, (input 23d engages the first output simultaneously21d and the second output 22d), a part of power that makes engine 4 by an output shaft (for example the first output shaft 21 orThe second output shaft 22) output driving Vehicle Driving Cycle, another part power is exported to the first dynamotor 51, drive motorsGenerating, has enriched transmission mode, takes into account Vehicle Driving Cycle and charging requirement.

Again describe the pattern of reversing gear, especially, there is the machinery mould that reverses gear according to the power drive system 100 of the embodiment of the present inventionFormula, electronic pattern and mixed moving three kinds of patterns of reversing gear of pattern of reversing gear of reversing gear.

The machinery pattern of reversing gear is to utilize the power of engine 4 to realize the car-backing function of vehicle, at vehicle in the machinery pattern of reversing gearTime, engine 4 as power source by the synchronous effect of reverse gear synchronizer 83c by the power of generation from the output gear that reverses gear84 outputs.

Particularly, in power drive system 100, in the time that machinery reverses gear pattern, reverse gear synchronizer 83c synchronous first reverses gearIdler gear 81 and the second reverse idler gear 82, the power that engine 4 produces exports the second power shaft 12 to, this partPower is again by two gear driving gear 2a, the second reverse idler gear 82, reverse gear synchronizer 83c, the first reverse idler gearAfter 81, export from the output gear 84 that reverses gear, realize reversing. In brief,, in the time that reversing gear pattern, machinery only has down at vehicleGear synchronized 83c is in engagement state.

The electronic pattern of reversing gear is to utilize the first dynamotor 51 to realize the car-backing function of vehicle, at vehicle in the electronic mould that reverses gearWhen formula, be divided into two kinds of concrete conditions.

The first situation: the first dynamotor 51 passes through motor mechanical axis the first synchronized 33c to motor as power sourceAfter the synchronous effect of the synchronous and reverse gear synchronizer 83c of mechanical axis the first gear 31 by the power of generation from the output gear that reverses gearWheel 84 outputs.

Particularly, as Figure 1-Figure 5, under operating mode, motor mechanical axis the first synchronized 33c engages motor mechanical axisThe first gear 31 and reverse gear synchronizer 83c engage the power that the second reverse idler gear 82, the first dynamotor 51 produceBy motor mechanical axis the first gear 31, four gear driving gear 4a, the second power shaft 12, two gear driving gear 2a, secondAfter reverse idler gear 82, reverse gear synchronizer 83c, the first reverse idler gear 81, export from the output gear 84 that reverses gear, realNow reversing. In brief, under this operating mode reverse gear synchronizer 83c in engagement state, simultaneously motor mechanical axis the first synchronized 33cEngage motor mechanical axis the first gear 31.

The second situation: the first dynamotor 51 passes through motor mechanical axis the second synchronized 34c to motor as power sourceSynchronously the power of generation being exported from the output shaft with the second motor gear 72 of mechanical axis the 3rd gear 33. Particularly,Under operating mode, motor mechanical axis the second synchronized 34c engages motor mechanical axis the 3rd gear 33, the first dynamotor 51The power producing is exported from the second output shaft 22 after by motor mechanical axis the 3rd gear 33, the second motor gear 72. Letter speechIt, only have motor mechanical axis the second synchronized 34c in engagement state under this operating mode.

The mixed moving pattern of reversing gear is to utilize engine 4 and the first dynamotor 51 to realize the car-backing function of vehicle simultaneously, mixed movingGear pattern is the reverse gear combination of pattern and the electronic pattern of reversing gear of above-mentioned machinery.

At vehicle in mixed moving while reversing gear pattern, engine 4 as dynamic origin by the synchronous of reverse gear synchronizer 83cThe power of generation is exported from the output gear 84 that reverses gear.

Meanwhile, the first dynamotor 51 passes through motor mechanical axis the first synchronized 33c to motor power as power sourceAfter the synchronous effect of the synchronous and reverse gear synchronizer 83c of axle the first gear 31 by the power of generation from the output gear that reverses gear84 outputs. Or the first dynamotor 51 passes through motor mechanical axis the second synchronized 34c to electricity as another power sourceSynchronously the power of generation being exported from the output shaft with the second motor gear 72 of motor-driven mechanical axis the 3rd gear 33.

Particularly, in mixed moving while reversing gear pattern, combine above-mentioned machinery reverse gear pattern and the in power drive system 100The electronic pattern of reversing gear of one or the second, engine 4 outputs power to according to the above-mentioned machinery pattern of reversing gear the output gear that reverses gear84, the first dynamotor 51 can output power to the output gear 84 that reverses gear according to the electronic pattern of reversing gear of above-mentioned the first,Thereby the power from engine 4 and the first dynamotor 51 is exported to wheel after output gear 84 places of reversing gear are coupled,Realize mixed moving reversing.

Or the first dynamotor 51 also can be defeated from the second output shaft 22 by power according to the electronic pattern of reversing gear of above-mentioned the secondGo out, thereby export after the 74 places coupling of main reducing gear driven gear from the power of engine 4 and the first dynamotor 51Give wheel, realize mixed moving reversing.

Thus, this power drive system 100 can realize three kinds of patterns of reversing gear, i.e. reverse gear pattern, the electronic pattern of reversing gear of machineryAnd the mixed moving pattern of reversing gear, enriching the operating mode of reversing gear, can in these three kinds of patterns of reversing gear, cut flexibly according to actual conditionsChange, meet and drive requirement.

For example, the in the situation that of Vehicular battery carrying capacity abundance, can adopt the electronic pattern of reversing gear, like this when reversing not onlyCan discharge of noxious gases, and can also reduce energy consumption, move backward for position for new driver especially, may need behaviourDo repeatedly could pour vehicle into assigned address, and engine 4 is owing to can producing more pernicious gas when the low-reverse,Engine 4 is generally in non-economy rotary speed area in the time of reversing simultaneously, and oil consumption is relatively high, now adopts the electronic pattern of reversing gearCan improve well this problem, not only can reduce discharge, adopt motor to realize low-reverse energy consumption as power simultaneouslyLower, the fuel economy of engine 4 is had to certain improvement.

And for example, inadequate or lower in the situation that at Vehicular battery carrying capacity, can adopt the machinery pattern of reversing gear. For another example exist,Need to move backward fast or need under the operating modes such as high-power reversing, can adopt the mixed moving pattern of reversing gear, increase the power of vehicleProperty, convenient reversing.

Certainly, the above-mentioned description about three kinds of model application environment that reverse gear is only schematically, can not be interpreted as it is to the present inventionA kind of restriction or hint under above-mentioned environment, must adopt the pattern of reversing gear of above-mentioned correspondence at vehicle. General for this areaLogical technical staff, obviously can be as required or actual conditions specifically set the mould that reverses gear required under corresponding reversing environmentFormula.

Thus, further enrich the pattern of reversing gear of power drive system 100, more selected to driver, fully improvedDriving, meets the requirement of reversing gear of different road conditions better.

According to the power drive system 100 of some embodiments of the present invention, as Figure 1-Figure 5, can also set up the second electricityMoving generator 52, to increase the dynamic property of power drive system 100, enriches transmission mode.

For example, therein in some embodiment, the second dynamotor 52 can with 74 transmissions of main reducing gear driven gear, exampleAs on the motor shaft of the second dynamotor 52, gear being set, this gear directly engages with main reducing gear driven gear 74Transmission. And for example, in further embodiments, the second dynamotor 52 also can be arranged to be connected with the first power shaft 11Or be connected with the first output shaft 21. For another example,, in some embodiment again, the second dynamotor 52 is two and establishes respectivelyPut in the both sides of differential mechanism 75, for example these two the second dynamotor 52 can become one with differential mechanism 75. Or,Aforesaid engine 4 and the first dynamotor 51 are for driving front-wheel, and the second dynamotor 52 can be also wheel limit electricityMachine for trailing wheel, or the second dynamotor 52 can drive two trailing wheels by a reducing gear, or the second electricityMoving generator 52 is two and drives a trailing wheel by a reducing gear respectively.
