The driving structure of the present embodiment can provide the following operation modes:
the first embodiment is as follows:
pure electric drive, as shown in fig. 2: when the electric quantity of the vehicle battery system meets a certain threshold value and is in a low-speed driving working condition with low starting or power requirement, the battery 05 provides electric energy for the driving motor 03, the driving motor 03 converts the electric energy into mechanical energy of the driving motor input shaft 40 to drive the third driving gear 300 to rotate, power is transmitted to the second intermediate shaft 50 through the third driven gear 310, then the power is transmitted to the differential gear 450 through the fifth driving gear 500, and finally the power is output through the differential 60.
Example two:
series drive, as shown in fig. 3: when the electric quantity of the vehicle battery system is insufficient and the vehicle runs at a low speed, the engine 01 is started, power is transmitted to the clutch shell through the torsional damper 02, and the clutch shell is connected with the generator 04, so that the generator 04 is driven to generate electricity. The generator 04 stores the generated electric energy in the battery 05, the battery 05 provides the electric energy to the driving motor 03, the driving motor 03 converts the electric energy into mechanical energy of the driving motor input shaft 40, drives the third driving gear 300 to rotate, transmits the power to the second intermediate shaft 50 through the third driven gear 310, transmits the power to the differential gear 450 through the fifth driving gear 500, and finally outputs the power through the differential 60.
Example three:
parallel drive, as shown in fig. 4: when the vehicle is running at a medium or low speed with a large throttle, the engine 01 transmits power to the first input shaft 10 through the torsional damper 02 and the first clutch 1, transmits power to the first intermediate shaft 30 through the first driving gear 100 and the first driven gear 110 engaged therewith, and then transmits power to the differential gear 450 through the fourth driving gear 400 fixed to the first intermediate shaft 30, and outputs power through the differential 60. When the engine 01 transmits power through the above route, the driving motor 03 also works at the same time, it converts the electric energy of the battery 05 into the mechanical energy of the driving motor input shaft 40, drives the third driving gear 300 to rotate, transmits the power to the second intermediate shaft 50 through the third driven gear 310, then transmits the power to the differential gear 450 through the fifth driving gear 500, and finally outputs the power through the differential 60.
The power output from the engine 01 can also be transmitted through the second clutch 2 via the second driving gear 200 and the second driven gear 210 according to different working condition requirements of the vehicle, and the rest is the same as above and is not described again.
