On the motor shaft of dynamotor 6, be provided with generator shaft gear 64, generator shaft gear 64 by the first intermediate gear 61, the second intermediate gear 62 and the 3rd intermediate gear 63 with the second input shaft gear 121 indirect drive, in conjunction with Fig. 1, generator shaft gear 64 and the 3rd intermediate gear 63 directly mesh, the second intermediate gear 62 and the 3rd intermediate gear 63 directly mesh, the second intermediate gear 62 and the first intermediate gear 61 are fixed on same axle, and the first intermediate gear 61 and the second input shaft gear 121 directly mesh.Not only can adjust thus the output speed of dynamotor 6, make the rotating speed of dynamotor 6 outputs be unlikely to too high, also take into account car load front deck space simultaneously and arranged.
Wherein, the first input shaft gear 111 forms low speed rotation gear with output shaft the first gear 31, and the second input shaft gear 121 forms high-speed drive gear with output shaft the second gear 32.
In this embodiment, the power output route of dynamotor 6 can be generator shaft gear 64, the 3rd intermediate gear 63, the second intermediate gear 62, the first intermediate gear 61, the second input shaft gear 121, output shaft the second gear 32, synchro 41, output shaft 3, output gear 33, diff 34.
The power output route of driving engine 5 is divided into two:
Low speed route is driving engine 5, double-clutch 2, the first input shaft 11, the first input shaft gear 111, output shaft the first gear 31, synchro 42, output shaft 3, output gear 33, diff 34;
High speed route is driving engine 5, double-clutch 2, the second input shaft 12, the second input shaft gear 121, output shaft the second gear 32, synchro 41, output shaft 3, output gear 33, diff 34.
Therefore because driving engine 5 has two output routes, at power drive system 100, during in generating operation mode, can realize quick generating and generate electricity at a slow speed two kinds of patterns.
When generating electricity fast, adopt high-speed drive gear to carry out power transmission, now can driving engine 5 be exported by the highest energy way of output by setting driving engine 5 in optimum operating condition, realize fast charge.And under this pattern, low speed rotation gear is because the power transmission with output shaft 3 is interrupted in the disconnection of synchro 42, be that output shaft the first gear 31 disconnects with output shaft 3, thereby the power having cut off between output shaft the first gear 31 and output shaft 3 is related, reduce external load, improve energy driving efficiency, simultaneously the first input shaft 11 due to output shaft 3 with the disconnection of output shaft the first gear 31 in static or low speed state, therefore it is too high and cause bearing defective that the first input shaft 11 is unlikely to rotating speed, and then improved the service life of double-clutch 2.
In addition, when driving vehicle by driving engine 5, also can adopt low speed rotation gear to generate electricity, now driving engine 5 can export power to output shaft 3 by the first input shaft 11, a part of power on output shaft 3 can be exported to diff 34 by output gear 33, and another part power can be exported to dynamotor 6 by high-speed drive gear.
The car load drive pattern participating in for driving engine 5, can specifically be divided into from low-speed mode and switch to fast mode and switch to low-speed mode from fast mode.
First describe from low-speed mode and switch to fast mode: when low-speed mode, the gear pair of being responsible for low speed rotation gear is in mode of operation, transmitting torque.Now driving engine 5 outputs power to the first input shaft 11, synchro 42 work and synchro 41 disconnect, power can export output shaft 3 from the first input shaft 11 to by output shaft the first gear 31, synchro 42, now driving engine 5 and the second input shaft 12 disconnect, and the second input shaft 12 is transmitting torque not.
When gearshift (upshift), synchro 41 engages, and after gearshift maturation on opportunity, electric-control system sends gear shifting signal, thus escape engine 5 and the first input shaft 11, and engage engine 5 and the second input shaft 12, to complete gearshift.After having shifted gears, separated synchro 42, disconnect the transmission of power between output shaft 3 and output shaft the first gear 31, avoid the first mouth 21 of output shaft the first gear 31, the first input shaft gear 111, the first input shaft 11 and double-clutch 2 to dally under high rotating speed servo-actuated, the life-span of causing power waste and reducing double-clutch 2.
Secondly describe and switch to low-speed mode from fast mode: when fast mode, the gear pair of being responsible for high-speed drive gear is in mode of operation, thus transmitting torque.Now driving engine 5 outputs power to the second input shaft 12, in running order and the synchro 42 of synchro 41 is in off-state, power can export output shaft 3 from the second input shaft 12 to by output shaft the second gear 32, synchro 41, now driving engine 5 and the first input shaft 11 disconnect, the first input shaft 11 is in idling conditions or quiescence, not transmitting torque.
Until gearshift, when (downshift), synchro 42 engages output shaft the second gears 32, after gearshift maturation on opportunity, disconnects the transmission of power between driving engine 5 and the second input shaft 12, then engage engine 5 and the first input shaft 11, thus complete gearshift.After having shifted gears, disconnect synchro 41, disconnect the transmission of power between output shaft 3 and output shaft the second gear 32, avoid the second mouth 22 of output shaft the second gear 32, the second input shaft gear 121, the second input shaft 12 and double-clutch 2 and dynamotor 6 to dally under high rotating speed servo-actuated, the life-span of causing power waste and reducing double-clutch 2.
For dynamotor 6 drives car load, double-clutch 2 can be in off-state, and synchro 41 is worked and synchro 42 disconnections.Dynamotor 6 can output power to output shaft 3, now the second mouth 22 idle running of double-clutch 2, and transmitting torque, has not reduced the wearing and tearing of double-clutch 2, has increased service life.Simultaneously due to synchro 42 separation, therefore the first mouth 21 of output shaft the first gear 31, the first input shaft 11, double-clutch 2 all can remain static or the rotation of slow speed of revolution inertia, further improved thus the life-span of double-clutch 2, greatly reduce follow-up unit simultaneously, improved driving efficiency.
In the example of Fig. 1, synchro 41 and synchro 42 are mainly the on and off switch as power transmission circuit, so layout can realize power more concentrated to demand direction transmission, reduce as far as possible or avoid other load power waste, improve charging or drive efficiency.Secondly; when dynamotor 6 high-speed drive gears drive and when driving engine 5 high-speed drive gears drive; synchro 42 disconnects; thereby avoid low speed rotation gear to follow rotation; so not only can improve and drive or generating efficiency; more can protect power drive system 100, extend the life-span of whole system, avoid fatigue failure.
To sum up, Fig. 1-power drive system 100 embodiment illustrated in fig. 4, at least tool has the following advantages:
1) radial structure is little, and dynamotor 6 while driving messenger chain short, driving efficiency is high, transmission degradation of energy is few;
2) when entering the charging of high-speed drive gear, synchro 42 disconnects, block the driving loss of the first mouth 21, the first input shaft 11, the first input shaft gear 111 and output shaft first gear 31 of double-clutch 2, improved charge efficiency, can realize fast charge;
3) when dynamotor 6 drives, power is exported to output shaft the second gear 32 and output shaft 3, synchro 42 disconnects, blocked the driving loss of the first mouth 21, the first input shaft 11, the first input shaft gear 111 and output shaft first gear 31 of double-clutch 2, improved drive efficiency, and friction lining Problem of Failure and the first input shaft 11 bearing defective problems of avoiding the first mouth 21 of double-clutch 2 to cause because rotating speed is too high.

For this embodiment, because input shaft gear one has four, output shaft gear correspondence is also four, therefore the corresponding gears in mesh of this four couple forms four pairs of driving gear pairs, to those skilled in the art, can be according to actual transmission needs, and specifically set the transmitting ratio of these four pairs of driving gear pairs, make power and the moment of torsion of power drive system output when carrying out power transmission with these four gears different, thereby meet better the power demand of vehicle.
In the embodiment of Fig. 5, driving engine 5 can drive car load to travel as propulsion source separately, under this pattern, by controlling the engagement state of double-clutch 2 and the engagement state of synchro 41,42, output speed and moment of torsion that can control engine 5, drive requirement thereby meet.
For example, driving engine 5 can output power to the first input shaft 11, synchro 41 can engage output shaft the first gear 31 or output shaft the second gear 32, thereby transmission power, or driving engine 5 can output power to the second input shaft 12, synchro 42 can engage output shaft the 3rd gear 36 or output shaft the 4th gear 37, thus transmission power.
Or, dynamotor 6 can drive car load to travel as propulsion source separately, under this pattern, synchro 43 engages generator shaft gear 64 and engages output shaft the 3rd gear 36 with motor shaft and synchro 42, and the power of now dynamotor 6 outputs can be exported by output shaft 3.
Again or, a part of power of driving engine 5 outputs can be by the second input shaft 12 and output shaft 3 outputs, another part power of driving engine 5 outputs can be exported to dynamotor 6, to drive dynamotor 6 generatings, under this pattern, synchro 43 engages generator shaft gear 64 and motor shaft, and synchro 42 engages one of output shaft the 3rd gear 36 and output shaft the 4th gear 37.
Again or, driving engine 5 and dynamotor 6 drive Vehicle Driving Cycle simultaneously, now from the power of driving engine 5 and dynamotor 6, export to output shaft the 3rd gear 36 therein after a second input shaft gear 121 places coupling, this part coupling power can be by the conjugation of synchro 42 from output shaft 3 outputs.
