5 rotation of wheel, gear frame gear 5 drive gear frame 6, and gear frame 6 drives two planetary gears 7 to rotate, due to anti-reverse gear 12
Planetary ring gear 4 is prevented to reverse, according to planetary gear train transmission principle, planetary gear 7 drives sun gear rotation, and sun wheel drive is universal
11 rotation of section, by 10 tire on the drive wheels 9 of rear axle, completes the output of power.
Under the first reluctance motor 16 not working condition: the second reluctance motor 1 is idle；Second reluctance motor 1 is
It is responsible for the motor of speed superposition, only in vehicle driving process in the suitable situation of load, i.e., is arrived in the first reluctance motor 16
Under certain speed conditions, and in the case of maximum value of the operating current no more than design, just the second reluctance motor 1 is allowed to participate in work
Make, this is completed by the electric-control system of vehicle.
