Motor driven gear ring is rotated, and driven by engine sun gear rotation, the rotating speed of planet carrier is determined by gear ring rotating speed and sun wheel speed,
That is nC=(1/ (1+k)) ne+(k/(1+k))nm.Motor torque and motor torque externally export after being superimposed on planet carrier.Power
Transfer route is:(M → gear ring)+(E → sun gear) → planet carrier → power output shaft → drive axle.The pattern is applied to vehicle
High-speed overload operating mode, using the speed governing of motor, engine speed can be made to work in high efficient district under different speeds.
(9) high speed traveling generates electricity:Now CS is combined, CT separation, B releases.Planetary gear train working condition icotype 8, no
Be engine power through planetary gear train a part driving automobilism, a part through motor to power source charges.Power passes
Passing route is:E → sun gear → (planet carrier → output)+(motor → gear ring is wired back).The pattern is applied to vehicle high-speed underloading
Operating mode, engine can be made to be in high efficient district and operate and reclaim part energy simultaneously.The pattern place different from pattern 8 is
Motor is operated in generating state, and motor is operated in driving condition in pattern 8.
(10) braking recovery:When vehicle is braked, according to vehicle difference speed state, CS, CT, B respective action, join table 1
Three kinds afterwards.And motor works in generating state, engine does not export power, realizes power recovery.
When automobile engine is damaged, then from M low speed list drive start, then the later stage be switched to M middling speeds list drive, drive extremely
Vehicle repairing factory is repaired;When vehicle electric motor damages, then from E low speed list drive start, then the later stage be switched to E middling speed lists
Drive, drive to vehicle repairing factory to be repaired.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
