Sun gear 3, planetary gear 5, planet carrier 4 and the gear ring 8 of planetary gear train are locked out and are integrated, rigidity operating.At this moment the first motor
10 and second motor 2 dally simultaneously, not passing power, the planetary gear rigidity machine that vehicle driving only passes through locking by engine 12
The direct passing power of structure, due to not passing through other energy conversions, vehicle transmission efficiency.
When vehicle is worked with high-power mechanical-electrical composite flooding pattern, as shown in Figure 5.When the vehicle accelerates, now need
Power may exceed engine peak power.At this moment by first clutch 11 and second clutch 9 in combination with braking
Device 1 unclamps the gear ring 8 of planetary gear train, the not locking of locking system 7.First motor 10 and the second motor 2 form of motor
Work.Under the management role of EMS 13, the electric energy of batteries 14 is supplied into the first motor 10 and second simultaneously
Motor 2.At this moment, the first motor 10 is driven by battery, drives planetary gear ring 8 to operate together with engine 12, simultaneously
Second motor 2 drives planetary sun gear 3 to operate due to obtaining the electric energy of battery, and differential planetary gear train is by engine
12nd, exported after the power coupled in common of the first motor 10 and the second motor 2, to meet power need when vehicle acceleration and climbing
Ask.
When vehicle is worked with energy recuperation mode, as shown in Figure 6.When car deceleration or descending, brake 1 is by planetary gear
The gear ring 8 of system is braked, the not locking of locking system 7, and at this moment sun gear 3, planetary gear 5, planetary wheel carrier 4 and gear ring 8 form one
The planetary reducer of single-degree-of-freedom, the second motor 2 are worked in the form of generator.Now by first clutch 11 and second
Clutch 9 is separated simultaneously, and the second motor 2 is driven by the inertia of vehicle to be started to generate electricity, and is to electric power storage by EMS 13
Pond is charged, and is at this moment achieved that energy regenerating and recycling, can be improved the utilization rate of electrical of vehicle.
