Embodiment
Refer to shown in Fig. 1, for embodiments of the invention, this embodiment is made up of engine 1, motor, 3, No. two motors 12, front planet row, rear planet row, output gear 16, invertor 17, super capacitor 18 and lock device 19, described No. two motors 12 are double-rotor machine, comprise internal rotor 13, stator 14 and outer rotor 15; Front-seat sun gear 4, front-seat planet carrier 7, front-seat satellite gear 5 and front-seat gear ring 6 are drawn together in described front planet package; Sun gear 11, rear seniority among brothers and sisters carrier 10, rear seniority among brothers and sisters star-wheel 8 and rear ring gear 9 are arranged in described rear planet package after drawing together; Described front-seat gear ring 6 shares a gear ring pedestal with rear ring gear 9; Described engine 1 is connected with front-seat planet carrier 7 by input shaft 2; Described front-seat sun gear 4 is connected with a motor 3, and lock device 19 one end is connected with front-seat sun gear 4 rotating shaft, and lock device 19 the other end is fixed on vehicle frame; After described, row's sun gear 11 is connected with No. two motor internal rotors 13, and rear seniority among brothers and sisters carrier 10 and No. two motor stators 14 are connected, and rear ring gear 9 is connected with No. two motor outer rotors 15; Described super capacitor 18 is connected with a motor 3, No. two motors 12 respectively by invertor 17; Output gear 16 outputting power on described gear ring pedestal is to drive axle.
Working process and the principle of the present invention are as follows:
1. engine starting pattern
Operation conditions according to whole car, engine starting pattern is divided into static startup and driving to start. The common trait of these two kinds of Starting mode is: lock device 19 is separated, super capacitor 18 discharges, and a motor 3 works in a form of an electric motor, and electric energy is converted into mechanical energy, power is delivered to engine 1 through front-seat sun gear 4, front-seat satellite gear 5, front-seat planet carrier 7, and engine 1 starts. The difference of two kinds of subpatterns is: during static startup, No. two motors 12 do not work, and front-seat gear ring 6 and rear ring gear 9 rotating speed are zero, and power transmission line is as shown in Figure 2; When driving starts, No. two motors 12 work in a form of an electric motor, and front-seat gear ring 6 and rear ring gear 9 rotating speed are not zero, and power transmission line is as shown in Figure 3.
2. electric-only mode
Electric-only mode is mainly used in when super capacitor 18 state-of-charge (SOC) value is higher, and vehicle start, underload travel and reversing. Under this pattern, lock device 19 is separated, super capacitor 18 discharges, the internal rotor 13 of No. two motors 12 works in a form of an electric motor, and electric energy is converted into mechanical energy, power through after arrange sun gear 11, after rank star-wheel 8, rear ring gear 9 deceleration increase torsion effect, it is delivered to output gear 16, exporting whole car drive axle again to, engine 1 and front-seat planet carrier 7 are fixed, and a motor 3 and front-seat sun gear 4 dally. During reversing, No. two motors 12 reverse, and other process is identical. Under this pattern, the required whole energy of vehicle movement is from super capacitor 18, and power transmission line is as shown in Figure 4.
3. engine drives separately pattern
Engine drives separately pattern to be mainly used in underload when middle load travels lower with super capacitor 18 state-of-charge (SOC) value and cruises, according to whole car operation conditions, engine drives separately pattern to be divided into power directly to transmit and shunts two kinds of subpatterns with power. When vehicle carries out middle load traveling, when whole car traveling demand power is in engine high-efficiency district, it is the direct transfer mode of power; Cruising when vehicle carries out underload, whole car travels the minimum power that power demand provides in efficient district lower than engine, and when super capacitor 18 state-of-charge (SOC) value is lower, is power shunt mode.
The common trait of these two kinds of subpatterns is: engine 1 works, power is passed to output gear 16 through input shaft 2, front-seat planet carrier 7, front-seat satellite gear 5, front-seat gear ring 6, exporting whole car drive axle again to, the required all power of vehicle movement all comes from engine 1; Rear ring gear 9, rear row's sun gear 11 and No. two motors 12 dally. The difference of two kinds of subpatterns is: when power directly transmits, and lock device 19 engages, and a motor 3 and front-seat sun gear 4 do not work, and the power that engine 1 exports is all for driving vehicle movement, and power transmission line is as shown in Figure 5; When power is shunted, lock device 19 is separated, a motor 3 works with the form of generator, mechanical energy is converted into electric energy, a part of power that engine 1 exports is for driving vehicle movement, another part is stored in super capacitor 18 with the form of electric energy, and now vehicle is in electronic infinite variable speed state, and power transmission line is as shown in Figure 6.
4. combine driving pattern
Associating driving pattern is mainly used in high loading and travels and run at high speed most. When vehicle carries out high loading traveling, lock device 19 engages, and a motor 3 and sun gear 4 do not work, super capacitor 18 discharges, and the internal rotor of No. two motors 12 works in a form of an electric motor, and electric energy is converted into mechanical energy, jointly driving vehicle with engine 1, power transmission line is as shown in Figure 7. When vehicle is run at high speed most, lock device 19 is separated, and super capacitor 18 discharges, and the outer rotor 15 of a motor 3 and No. two motors 12 works all in a form of an electric motor, and engine 1 drives vehicle jointly, and power transmission line is as shown in Figure 8; Now a motor 3 reverses.
5. braking mode
When super capacitor 18 state-of-charge (SOC) value is lower and the speed of a motor vehicle higher than certain value time, vehicle can carry out regenerative braking, lock device 19 is separated, a motor 3 dallies, No. two motors 12 work with the form of generator, the braking energy reclaimed is filled with super capacitor 18 with the form of electric energy, and power transmission line is as shown in Figure 9.
It is noted that when No. two motors 12 are not enough to provide required braking moment, vehicle will adopt the Associated brake pattern of regenerative braking, engine anti-dragged brake and friction braking acting in conjunction.
