C3 and power output portion 300 is set to successively increase in the axial direction of power input shaft 1 at a distance from engine 200.Optionally, start
Machine 200 can be horizontal or longitudinal.Such arragement construction is disposed adjacent engine 200 with motor generator and is conducive to
Power transmission reduces the energy consumption in drive path.
For to sum up, power drive system 1000 according to an embodiment of the present invention, by planetary gear mechanism P and two from
It attaches together and sets combination, make power drive system 1000 that there is one of multiple-working mode, such as two motor generators to be operated alone
Or two motor generators drive simultaneously, the mixed connection drive mode of two speed ratios, engine 200 directly drives total with three power sources
Same drive mode.Particularly, power drive system 1000 according to an embodiment of the present invention increases engine 200 and directly drives
The mixed connection drive mode of mode and two gears.When running at high speed, two arrangement of clutch, which simultaneously engage with, makes planet carrier 3 and gear ring
4 be connected with each other, engine 200 can direct output power, avoid motor generator power generation, motor generator driving energy
The energy loss of conversion process improves economy of the power drive system 1000 in high-speed working condition.In mixed connection drive mode
When, the revolving speed by adjusting motor generator makes engine 200 may remain in high efficiency revolving speed section travel, and passes through choosing
Selecting property engages one of two arrangement of clutch, keeps the motor generator being connected with the arrangement of clutch of engagement dynamic as driving motor output
Power, and another motor generator is as generator, in this way setting make mixed connection drive mode tool there are two gears, improve power
The speed regulation capacity of transmission system 1000, when two arrangement of clutch simultaneously engage with, the driving or two simultaneously of two motor generators
A motor generator and engine 200 drive simultaneously, make system have good dynamic property, can satisfy starting, accelerate and on
Power demand when slope.In power generation in parking mode, two arrangement of clutch are separated, and engine 200 works in efficient revolving speed area
Between, two motor generators generate electricity maximize generating efficiency simultaneously.
In conclusion the present invention has the economy of more wide speed range, it may have very strong dynamic property.
In addition, power drive system 1000 according to the present invention, the first motor generator MG1, planetary gear mechanism P,
Second motor generator MG2, the second arrangement of clutch C2, third arrangement of clutch C3 and the connection relationship in power output portion 300 with
And on the basis of working condition, the first motor generator MG1, planetary gear mechanism P, the second motor generator are creatively arranged
MG2, the second arrangement of clutch C2, third arrangement of clutch C3 and the position in power output portion 300, not only realize a variety of different
Operating mode, and each operating mode is suitable for different operating conditions, and ensures splendid fuel economy and comfort, and mode is cut
It changes that structure is simple, also makes the compact overall structure of power drive system 1000, arrangement space is small, and structure is simple and easy to implement.
In short, power drive system 1000 according to an embodiment of the present invention, operating mode multiplicity and each operating mode is cut
Change simple, vehicle low speed has good economy when running at high speed, and when low speed, engine stabilizer works in economic speed section；
When high speed, engine 200 is mechanically directly exported, high-efficient, and especially engine 200 can be by arranging single-stage planetary gear train
The direct output power of P improves the economy of high-speed working condition, while when power generation in parking mode, two motor generators generate electricity,
Generating efficiency is high, and the structure realized is simple, characteristics of compact layout.
Vehicle according to an embodiment of the present invention is briefly described below, which includes above-mentioned power drive system 1000,
Thus the advantages that economical high, energy conversion loss is small and power generation in parking is high-efficient.
