It is briefly described below for the typical condition of the power drive system 100 of the illustrated embodiment in Fig. 1.

Parking charging operating mode:

The input terminal 23d of double clutch 2d engages the first output end 21d and is disconnected with second output terminal 22d, to start The input terminal 23d, the first output end 21d, the first input shaft 11, seven that the power that machine 4 exports passes through double clutch 2d successively keep off tooth Output is to the first dynamotor 51 after wheel set, the second output shaft 22, to which the first dynamotor 51 of driving generates electricity.

Alternatively, the input terminal 23d of double clutch 2d engages second output terminal 22d and is disconnected with the first output end 21d, six gears Six gear driven gear 6b of synchronizer 6c engagements, to which the power that engine 4 exports passes through the input terminal of double clutch 2d successively Output is to the first dynamotor after 23d, second output terminal 22d, the second input shaft 12, six gear gear pair, the second output shaft 22 51, to which the first dynamotor 51 of driving generates electricity.

It is understood that in above-mentioned two situations, empty set output gear synchronizer 31c is in disengaged condition, i.e., Off-state.

It can realize the charging of two kinds of speed ratios under the operating mode, energy transfer efficiency higher, and about the selected of speed ratio and is started The permitted highest of additional components such as the type selecting of rotating speed, the first dynamotor 51 when 4 parking of machine and periphery bearing turns Speed has direct relation, and for the ordinary skill in the art, the factors such as above that can integrate account for, flexible design Corresponding transmission speed ratio so that power drive system 100 can maximumlly utilize the energy of engine 4 in power generation in parking, Reach quick charge purpose.Particularly, when transmitting the power of engine 4 by seven gear gear pairs, due to seven gear transmission speed ratios Maximum, therefore the first dynamotor 51 can maximally utilize the energy of the output of engine 4, improve charge efficiency.

Pure electric vehicle operating mode:

Empty set output gear synchronizer 31c engagement empty sets output gear 31, to moving for the first dynamotor 51 output Power after the second output shaft 22, empty set output gear synchronizer 31c from empty set output gear 31 by exporting.As a result, transmission chain compared with Short, transmission efficiency is higher.Alternatively, the first dynamotor 51 can also output power to the first input by seven gear gear pairs Axis 11, one or three gear synchronizer 13c are selectively engaged the gear driven gear 3b of a gear driven gear 1b or three at this time, thus the first electricity The power of dynamic generator 51 can finally be exported by first gear pair or three gear gear pairs from the first output shaft 21.

Hereby it is achieved that more gears driving in the case of pure electric vehicle, can flexibly select suitable move according to different paths Power outgoing route, to preferably meet the driving demand of user.

When power drive system 100 is in above two pure electric vehicle operating mode, the first dynamotor 51 is as electronic Machine work, and the first dynamotor 51 can for example (schematically illustrate) direction rotates work clockwise along preset rotating direction Make.

Optionally, of course, the first dynamotor 51 can also be by the synchronization of reverse gear synchronizer 83c by the power of generation It is exported from fixed reverse gear 82, i.e. reverse gear synchronizer 83c synchronizes empty set reverse gear 81 and the second output shaft 22, to first The power that dynamotor 51 exports can be fallen by the second output shaft 22, reverse gear synchronizer 83c, empty set reverse gear 81, fixation It keeps off after gear 82 and exports onward impulse from the first output shaft 21.

However, it is desirable to which explanation, passes through empty set reverse gear 81, fixed reverse gear 82 in the first dynamotor 51 When this path exports onward impulse, the first dynamotor 51 needs to invert rotary work for example counterclockwise.Each gear is mixed dynamic Operating mode:

First by taking empty set output gear synchronizer 31c engagement empty set output gear 31 as an example, the first dynamotor at this time The power of 51 outputs can be by exporting after the second output shaft 22, empty set output gear synchronizer 31c from empty set output gear 31.And Engine 4 can export power by second gear pair, four gear gear pairs, six gear gear pairs or seven gear gear pairs at this time, in other words, Engine 4 can keep off gear pair by the first input shaft 11, seven and export power or 4 energy of engine from the second output shaft 22 Power is exported by the second input shaft 12, second gear pair or four gear gear pairs from the first output shaft 21 enough, or passes through six Gear gear pair exports power from the second output shaft 22.

According to the difference of 4 power transmission path of engine, power and the first dynamotor 51 from engine 4 move Power can couple on the second output shaft 22, can also be coupled on main reducing gear driven gear 74 certainly, the power after coupling can The wheel that both sides are distributed to by differential mechanism 75, to drive vehicle to travel.

This it is mixed start building under condition, the first dynamotor 51 can carry out speed governing, so that the second output shaft 22 or main Retarder driven gearwheel 74, which can be synchronized evenly, receives the power from engine 4 and the first dynamotor 51, improves The ride comfort of transmission, harmony.

Secondly, power drive system 100 be in it is mixed start building condition when, empty set output gear synchronizer 31c can also be in Off-state, at this time the first dynamotor 51 by seven gear gear pairs output power to the first input shaft 11, engine 4 can Power is equally exported to the first input shaft 11, two parts power can pass through first gear pair after being coupled on the first input shaft 11 Or exported from the first output shaft 21 after third gear pair, the first dynamotor 51 can carry out speed governing at this time, so that the One input shaft 11, which can be synchronized evenly, receives the power from engine 4 and the first dynamotor 51, improves transmission Ride comfort, harmony.

Alternatively, in the case where empty set output gear synchronizer 31c is off, engine 4 can also be defeated by power Go out to the second input shaft 12, and is exported to the first output shaft 21, the first dynamoelectric and power generation by second gear pair or four gear gear pairs Machine 51 by first gear pair or three gear gear pairs after seven gear gear pairs, the first input shaft 11 by that can output power to first Output shaft 21, two parts power may be output to main reducing gear driven gear 74 after being coupled on the first output shaft 21.At this time first Dynamotor 51 can carry out speed governing so that the first output shaft 21 can evenly synchronize reception from engine 4 with And first dynamotor 51 power, improve ride comfort, the harmony of transmission.

For the ordinary skill in the art, can power neatly be exported to above-mentioned first dynamotor 51 Path and engine 4 export power path be combined, to meet driving demand, enrich power drive system 100 Transmission mode, improve driving pleasure, enable the vehicle to better adapt to different road conditions, improve dynamic property, the fuel oil of vehicle Economy.

Power drive system 100 be in above-mentioned each gear it is mixed start building condition when, the first dynamotor 51 is as electronic Machine work, and the first dynamotor 51 still can be along above-mentioned preset rotating direction (schematically illustrate) direction for example clockwise Rotary work.

Engine charges operating mode in driving:

What one of the input terminal 23d and the first output end 21d or second output terminal 22d for describing double clutch 2d first were engaged Situation.For example, input terminal 23d only engages the first output end 21d, the partial power of engine 4 can pass through the first input shaft 11, seven Gear pair, the output of the second output shaft 22 are kept off to the first dynamotor 51, to which the first dynamotor 51 of driving generates electricity. Another part power of engine 4 can by the first input shaft 11, after first gear is secondary or three gear gear pairs from the first output shaft 21 outputs can also be exported by seven gear gear pairs from the second output shaft 22 certainly.

For another example, input terminal 23d only engages second output terminal 22d, and the partial power of engine 4 can pass through the second input shaft 12, six gear gear pairs, the output of the second output shaft 22 are to the first dynamotor 51, to which the first dynamotor 51 of driving carries out Power generation.Another part power of engine 4 can be exported by six gear gear pairs from the second output shaft 22, can also pass through two gears certainly Gear pair or four gear gear pairs are exported from the first output shaft 21.

Secondly the input terminal 23d of description double clutch 2d simultaneously engages with the feelings of the first output end 21d and second output terminal 22d Condition.In this case, the partial power of engine 4 can keep off gear pair by the first input shaft 11, seven, the second output shaft 22 exports To the first dynamotor 51, to which the first dynamotor 51 of driving generates electricity.Another part power that engine 4 exports It can be exported from the first output shaft 21 by the second input shaft 12, second gear pair or four gear gear pairs.

Hereby it is achieved that the breakthrough application to double clutch 2d, that is, realize and simultaneously engage with situation in double clutch 2d Under charge operating mode in driving, to further enrich the transmission mode of power drive system 100, improve power transmission The dynamic property of system 100.

To sum up, for the ordinary skill in the art, above-mentioned start can neatly be selected according to actual needs The arbitrary drive path that machine charge in driving in operating mode, is greatly enriched the transmission mode of power drive system 100, raising Driving pleasure, enables the vehicle to better adapt to different road conditions, improves dynamic property, the fuel economy of vehicle.

In addition, when charging when power drive system 100 is in engine in driving, the first dynamotor 51 is conduct Generator operation, and the first dynamotor 51 still can be along above-mentioned preset rotating direction for example clockwise (schematically illustrate) Direction rotary work.

It reverses gear operating mode:
