The partial power is passed to fixed the first transmission gear 431 on it, institute by the first output shaft 44, first output shaft 44
It states the first transmission gear 431 and the power is passed into differential mechanism 433 again, the power is passed into vapour eventually by differential mechanism 433
Vehicle wheel 5.
2) torque drive mode in
Specifically, on the basis of above-mentioned small torque drive mode, the second motor 32 is same for torque drive mode in realization
When driving force is provided, and it is a certain by the way that third shifting element 377 that second changes in component 37 or the 4th shifting element 378 to be linked into
After a gear, the transmission of the power of the second motor 32 is realized, vehicle driving is driven, specifically, by the second shift assembly 47
Third shifting element 477 is placed in the left gear of the first output shaft 44, and second shift assembly 47 is in five gear speed change states, this
When, the tenth gear 473 and eighth gear 471 engage, and second input shaft 42 passes sequentially through eighth gear 471 and the tenth
The power of second motor 32 is passed to the first transmission gear 431 by gear 473, and first transmission gear 431 transmits power
To differential mechanism 433, the power of second motor 32 is transmitted into an automotive wheel 5 eventually by differential mechanism 433, at automotive wheel 5
The power of second motor 32 is mixed with the power at small torque drive mode, is travelled eventually by the hybrid drive vehicle.
Further, above-mentioned driving process is to keep off driving and five gear drivings by one just for the sake of cited by understanding
Real-time mode, can be driven by random shift of the gear into eight gears, it is real after being engaged especially by different gears
Existing power transmitting, specific engagement system have been described above, and which is not described herein again.
Three, braking momentum recycles function
When driver touches on the brake, first motor 31 and the second motor 32 can absorb power and charge a battery,
Generate brake force.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
