Working principle
The gear CVT (continuously variable transmission) does not need fluid torque converter to connect, and need not clutch yet and connects, and the input shaft of gear CVT (continuously variable transmission) can directly be connected with the output shaft of motor, because of this gear CVT (continuously variable transmission) built-in clutch.
When output shaft under loading condition, rotating speed on the motor transmission input shaft is through the deceleration rotating machinery, make rotary shell 12 counterrotatings, ring gear 25 is with the input shaft counterrotating in the magnetic force adjustment control mechanism that is connected with rotary shell, and clutch sun gear 58 is in the clutch separated position, and coil does not have energising on stator iron core 36 and the rotor iron core 38, there is not magnetic field to form, whole magnetic force speed regulation control mechanism is all oppositely idle running on output shaft, and the output shaft rotating speed is zero, is in idling mode.
Impose on when quickening, external oil pump feed, oil inner cylinder sleeve 45 stretches and compresses clutch plate 53, slip ring 41, rotor iron core 38, clutch sun gear 58 are combined into one with output shaft, the rotation of clutch sun gear drive planetary gear set subtracts turns round speedup, makes magnetic control mouse cage sun gear 55 high speed rotating.When engine speed improves, begin power supply through carbon brush 40, slip ring 41 connecting coils, rotor iron core is produced under the effect from weak to strong of magnetic field, output shaft is from the identical slow starting with steering input shaft of static beginning, make magnetic control mouse cage sun gear magnetic control on a certain constant rotational speed or accelerate to gradually and reach synchronously with iron core, at this moment output shaft and input shaft rotating speed equate.It is asynchronous with the rotor iron core generation to the hysteresis of magnetic control mouse cage sun gear that rotor iron core coil blackout, stator iron core coil electricity produce magnetic field when needs output shaft rotating speed is higher than the input shaft rotating speed, and the output shaft rotating speed is higher than input shaft, and this moment, automobile was for running at high speed.
During reversing, motor turns to constant, output shaft need reverse, it is 4 locked by reverser handle reverse clutch 7 to be coiled reversing, the primary planet carrier 10 that is connected with the reversing dish is static, makes rotary shell 12 counterrotatings, because the third-level planetary gear is to be contained on the planet carrier of output shaft, the output shaft and the rotation ring gear that slows down rotate in the same way, form reversing with the input shaft counterrotating.
