The specific embodiment
In conjunction with accompanying drawing the dynamic coupling system structure of the motor vehicle driven by mixed power of the utility model is explained.
As shown in Figure 1, the dynamic coupling system of the motor vehicle driven by mixed power of the utility model includes driving engine, twin-stage sun and planet gear, first motor, second motor, and said first motor 5 is a hollow shaft motor, and second motor 6 is the solid axle motor; The output shaft of said driving engine connects with the gear ring 1 of twin-stage sun and planet gear; The hollow shaft of said first motor 5 connects with the sun gear 4 of twin-stage sun and planet gear; The hollow shaft that the solid axle of said second motor 6 passes said first motor 5 connects with the pinion carrier 2 of twin-stage sun and planet gear; The power that forms 6 two propulsion source outputs of said driving engine and said second motor is coupled through said twin-stage sun and planet gear, exports to transmission shaft.
The dynamic coupling system of this motor vehicle driven by mixed power connects the hollow shaft of sun gear 4 with first motor 5, and pinion carrier 2 is connected and connect transmission shaft with the solid axle of second motor 6, and gear ring 1 is connected with the output shaft of driving engine.The rotating speed and the torque of driving engine output are directly passed to gear ring; The rotating speed and the torque of second motor, 6 outputs of solid axle are directly passed to pinion carrier 2.The rotating speed and the torque of second motor, 6 outputs of the rotating speed of driving engine output and torque and solid axle are coupled through the twin-stage sun and planet gear.
As shown in Figure 2, pure electronic operating mode: promptly by second motor 6 of solid axle as the drive source powered vehicle.Driving engine does not start, and promptly gear ring is fixed, and second motor, 6 output speeds of solid axle and transmission of torque are that pinion carrier is a driving link to pinion carrier, first motor, 5 contrarotations of hollow shaft but do not generate electricity, and sun gear is a driven member, turns to pinion carrier 2 reverse.
As shown in Figure 3, the series hybrid operating mode: promptly by first motor, 5 generatings of engine drives hollow shaft, second motor 6 of solid axle is as the drive source powered vehicle.Driving engine output speed and transmission of torque are that gear ring is a driving link to gear ring, and rotating speed that gear ring is suffered and torque pass to sun gear by planetary wheel to drive 5 generatings of hollow shaft first motor be that sun gear is a driven member, turn to gear ring in the same way.First motor, 5 electricity of hollow shaft flow to solid axle second motor 6 through frequency converter, second motor 6 of solid axle be pinion carrier output speed and torque to turning cylinder, turn to gear ring in the same way.
As shown in Figure 4, parallel connection mixes operating mode: promptly second motor 6 of driving engine and solid axle is simultaneously as propulsion source, and powered vehicle is gone.Driving engine output speed and torque are that gear ring is a driving link, and rotating speed and torque pass to pinion carrier through the twin-stage planetary wheel; Second motor, the 6 while output speed of solid axle and torque are that pinion carrier also is driving link, powered vehicle simultaneously to pinion carrier.Hollow shaft first motor 5 can be regulated the driving engine output speed as the control auxiliary member.
As shown in Figure 5, series-parallel connection mixes operating mode: promptly engine output power both powered vehicle go, drive first motor, 5 generatings of hollow shaft again simultaneously.Driving engine output speed and torque are that gear ring 1 is driving link.Wherein a part of rotating speed and torque output passes to pinion carrier 2 through twin-stage planetary wheel 3, pinion carrier 2 turn to gear ring 1 in the same way.All the other rotating speeds and torque pass to first motor, 5 rotors that sun gear 4 is a hollow shaft through twin-stage planetary wheel 3, first motor 5 generating of hollow shaft, turn to gear ring 1 in the same way.The electricity that first motor 5 of hollow shaft sends can offer second motor 6, the second motors, 6 outputting powers and the driving engine driven in common vehicle ' of solid axle.
As shown in Figure 6; Engine starting operating mode: through gear ring 1, pinion carrier 2, sun gear 4 three's movement relations; With second motor, 6 rotors of solid axle be pinion carrier 2 as fixedly reference, first motor 5 through hollow shaft be sun wheel as driving link, the gear ring 1 that connects driving engine is a driven member; Drive gear rings 1 start the engine through twin-stage planetary wheel 3, turn to first motor 5 with hollow shaft be sun gear 4 in the same way.
As shown in Figure 7, braking energy reclaims operating mode: second motor 6 of solid axle is that transmission shaft is braked as electrical generator to pinion carrier 2, service vehicle's braking.Driving engine is in the idling work state, and first motor 5 of hollow shaft is in free state, and the energy of car brakeing is reclaimed, and charges a battery.If it is that gear ring 1 is fixing that driving engine is not worked, then sun wheel is first motor, 5 counter-rotatings of hollow shaft and is in free state.
