Refer to shown in Fig. 1, for embodiments of the invention, this embodiment is made up of driving engine 1, motor 3, No. two motors 12, front planet row, rear planet row, output gear 16, inverter 17, super capacitor 18 and mechanical brakes 19, described No. two motors 12 are double-rotor machine, comprise internal rotor 13, stator 14 and outer rotor 15; Front-seat sun wheel 4, front-seat pinion carrier 7, front-seat satellite gear 5 and front-seat gear ring 6 are drawn together in described front planet package; Described rear planet row comprises rear row's sun wheel 11, rear seniority among brothers and sisters carrier 10, rear seniority among brothers and sisters star-wheel 8 and rear ring gear 9; Described front-seat gear ring 6 shares a gear ring pedestal with rear ring gear 9; Described driving engine 1 is connected with front-seat pinion carrier 7 by input shaft 2; Described front-seat sun wheel 4 is connected with a motor 3, and mechanical brake 19 one end is connected with the rotating shaft of front-seat sun wheel 4, and mechanical brake 19 other end is fixed on vehicle frame; Described rear row's sun wheel 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 inverter 17; Output gear 16 outputting power on described gear ring pedestal is to drive axle.
Working process of the present invention and principle as follows:
1. engine starting pattern
According to the operation conditions of car load, engine starting pattern is divided into static startup and driving to start.The common trait of these two kinds of Starting mode is: mechanical brake 19 is separated, super capacitor 18 discharges, and a motor 3 works in a form of an electric motor, is mechanical energy by electric energy conversion, power is delivered to driving engine 1 through front-seat sun wheel 4, front-seat satellite gear 5, front-seat pinion carrier 7, and driving engine 1 starts.The difference of two spermotypes 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 as shown in Figure 2; Driving start time No. two motors 12 work in a form of an electric motor, front-seat gear ring 6 and rear ring gear 9 rotating speed non-vanishing, 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, mechanical brake 19 is separated, super capacitor 18 discharges, the internal rotor 13 of No. two motors 12 works in a form of an electric motor, is mechanical energy by electric energy conversion, power through after arrange sun wheel 11, after rank star-wheel 8, rear ring gear 9 deceleration increase torsion effect, be delivered to output gear 16, export car load drive axle again to, driving engine 1 and front-seat pinion carrier 7 are fixed, and a motor 3 and front-seat sun wheel 4 dally.During reversing, No. two motors 12 reverse, and other process is identical.Under this pattern, vehicle travels required whole energy from super capacitor 18, and power transmission line as shown in Figure 4.
3. the independent drive pattern of driving engine
The independent drive pattern of driving engine be mainly used in middle load and super capacitor 18 state-of-charge (SOC) value lower time underload cruise, according to car load operation conditions, the independent drive pattern of driving engine is divided into power directly to transmit and power dividing two spermotype.When vehicle carries out middle load, when car load traveling demand power is in engine high-efficiency district, be the direct transfer mode of power; Cruise when vehicle carries out underload, the minimum power that car load road horsepower demand provides in efficient district lower than driving engine, and when super capacitor 18 state-of-charge (SOC) value is lower, be power dividing pattern.
The common trait of this two spermotype is: driving engine 1 works, power is passed to output gear 16 through input shaft 2, front-seat pinion carrier 7, front-seat satellite gear 5, front-seat gear ring 6, export car load drive axle again to, vehicle travels required all power and all comes from driving engine 1; Rear ring gear 9, rear row's sun wheel 11 and No. two motors 12 dally.The difference of two spermotypes is: when power directly transmits, and mechanical brake 19 engages, and a motor 3 and front-seat sun wheel 4 do not work, and the power that driving engine 1 exports is all for driving vehicle to travel, and power transmission line as shown in Figure 5; During power dividing, mechanical brake 19 is separated, a motor 3 is with the form work of electrical generator, be electric energy by changes mechanical energy, a part of power that driving engine 1 exports travels for driving vehicle, 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 as shown in Figure 6.
4. combine drive pattern
Associating drive pattern is mainly used in high load capacity and travels and run at high speed most.When vehicle carries out high load capacity traveling, mechanical brake 19 engages, and a motor 3 and sun wheel 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, is mechanical energy by electric energy conversion, jointly drive vehicle with driving engine 1, power transmission line as shown in Figure 7.When vehicle is run at high speed most, mechanical brake 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 driving engine 1 drives vehicle jointly, and power transmission line as shown in Figure 8; Now a motor 3 reverses.
5. braking mode
When the lower and speed of a motor vehicle of super capacitor 18 state-of-charge (SOC) value is higher than certain value, vehicle can carry out regenerative brake, mechanical brake 19 is separated, a motor 3 dallies, No. two motors 12 are with the form work of electrical generator, the braking energy reclaimed is filled with super capacitor 18 with the form of electric energy, and power transmission line as shown in Figure 9.
It is pointed out that, when No. two motors 12 are not enough to provide required lock torque, vehicle will adopt the coefficient Associated brake pattern of regenerative brake, driving engine anti-dragged brake and friction braking.
