The 3rd input shaft 8 is stated, so as to drive the ISG motors 3 to be rotated, carries out sending out by using the rotation of the ISG motors 3
Electricity, therefore, it is possible to provide energy for the main drive motor 1.
4th, paralleling model：
(1) the first assistant mode in parallel, main drive motor 1 drives the first input shaft 2 to be rotated, by reduction gearing
Pair, eventually passes the output power of output shaft 9；By first clutch 4, second clutch 5 in combination with axle, by using engine
6 provide power, and power can be transferred to the 4th tooth by power through first clutch 4 and second clutch 5 using the 3rd gear
Wheel, power is transferred on first input shaft 2, forms the power-assisted to main drive motor 1；
(2) second assistant mode in parallel, on the basis of the first assistant mode in parallel, start ISG motors 3, pass through
Using ISG motors 3, power can be transferred into second gear, first gear using the 3rd input shaft 8, drive described the
Two clutches 5 are moved, and power is transferred into the 3rd gear, the 4th gear, now the engine 6 and the ISG
Motor 3 can be collectively forming to the main power-assisted for driving motor 1；
(3) the third assistant mode in parallel, main drive motor 1 quits work, by the first clutch 4, described second from
Clutch 5 is combined, and starts the ISG motors 3, and the ISG motors 3 can transmit power by using the 3rd input shaft 8
To second gear, first gear, and power is transferred into the second clutch 5, simultaneously because the first clutch 4 and institute
State second clutch 5 to be connected, start the engine 6, the engine 6, can be electric by the ISG under lower-speed state
The drive of machine 3 quickly carries out high-speed rotation pattern, meanwhile, the engine 6 can be passed power by second input shaft 7
The first clutch 4 is handed to, now, the power that the engine 6 and the ISG motors 3 are provided can jointly through described
Second clutch 5 is transferred to the 3rd gear, and power is transferred into the first input shaft 2 by the 4th gear, and then power is steady
It is transferred to the output shaft 9.
5th, energy feedback pattern：
Energy feedback due to power output pattern conversely, vehicle braking procedure or it is static when, when described first from
When clutch 4 and the second clutch 5 disconnect, energy is transferred to first input shaft 2 by first output shaft 9, enters
And the main drive motor 1 is fed back to, the main drive motor 1 can complete energy regenerating；Same reason, when second clutch
When device 5 is in combination with axle, axle can be flowed to by the output shaft 9, and then by the first gear and the second tooth
Wheel, eventually through the 3rd input shaft 8 the ISG motors 3 are flowed to, and realize energy regenerating.
Corresponding pattern in parallel or in series can be completed according to different operating modes by above technical scheme, actually made
With during, driver can more accurately be selected as needed, with save energy.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, some deformations and improvement can also be made, these belong to the present invention
Protection domain.
