It can be single clutch to attach together and put 7, and single clutch can control the engagement between the dynamotor 6 of engine 1 and second to disconnect,
And the engagement between engine 1 and input 51d can be controlled to disconnect.By setting the second arrangement of clutch 7, can rationally control
The power generation in parking state of the second dynamotor 6 is made, so that power-driven system 100 is simple in construction and drive pattern
Conversion is reliable.
Preferably, the second arrangement of clutch 7 is built in the internal rotor of the second dynamotor 6.So can preferably it contract
The axial length of short power-driven system 100, so as to reduce the volume of power-driven system 100, power drive can be improved
Dynamic flexible arrangement of the system 100 on vehicle 1000.In addition, when the second dynamotor 6 is also used as starter motor use.
Preferably, the input 51d of engine 1, the second arrangement of clutch 7 and double clutch is coaxially arranged.So can be with
So that power-driven system 100 is compact-sized, small volume.
It should be noted that for the power-driven system 100 of above three embodiment, in the axial direction, the second electricity
Dynamic generator 6 is respectively positioned between the arrangement of clutch 5d of engine 1 and first, so can effectively reduce power-driven system 100
Axial length, and can make it that the location arrangements of the second dynamotor 6 are reasonable, power-driven system 100 can be improved
Structural compactness.
First dynamotor 4 is the main drive motor of power-driven system 100, so the appearance of the first dynamotor 4
Amount and volume are larger, by setting motor power axle 41, can reduce the volume of power-driven system 100 to greatest extent, and
And it can avoid interfering phenomenon between the first dynamotor 4 and the second dynamotor 6.
Wherein, for the first dynamotor 4 and the second dynamotor 6, the specified work(of the first dynamotor 4
Rate is more than the rated power of the second dynamotor 6.Such second dynamotor 6 can choose small volume and rated power is small
Dynamotor so that power-driven system 100 is simple in construction, small volume, and in power generation in parking, second
Drive path is short between dynamotor 6 and engine 1, and generating efficiency is high, so as to effectively move a part for engine 1
Power changes into electric energy.Wherein peak power of the peak power of the first dynamotor 4 also greater than the second dynamotor 6.
Preferably, the rated power of the first dynamotor 4 is twice or two of rated power of the second dynamotor 6
More than times.The peak power of first dynamotor 4 is twice or more than twice of the peak power of the second dynamotor 6.
