Brake is provided between the outer gear ring and shell of train；The sun gear of the power input shaft and/or the planetary gear train
The speed change gear is connected to by second clutch.
Using the above structure, since power input shaft penetrates rotatably motor and shell, second clutch is disconnected, so that it may
To cut off the power transmission of engine, pure motor drive mode is realized, under this drive mode, in conjunction with first clutch, disconnect
Brake, it will be able to which primary speed-down output is carried out with the reduction ratio between the first driving wheel and the second driving wheel；In conjunction with brake,
Disconnect first clutch, it will be able to the reduction ratio between the reduction ratio of planetary gear train and the first driving wheel and the second driving wheel
Product carry out double reduction output.In this way, realizing pure motor-driven two stage speed change, power of motor is advantageously reduced, together
When ensure that motor efficiently exports.And under pure engine drive mode, engine direct tape splicing moves speed change gear, the rotor of motor with
Power input shaft relatively rotates, and weak magnetic loss of torque when so as to avoid rotor from dallying is conducive to improve pure start
Delivery efficiency under machine drive mode.
Further, the speed change gear is CVT speed changer.
It is whole that there is good fuel economy when may insure engine driving using CVT speed changer.Meanwhile may be used also
To reduce the size of entire power drive system, structure is more compact, is easily installed and arranges.When pure engine exports, entirely
Variator ratio range is the 2 gear combinations of CVT belt wheel speed ratio and planetary gear train, can increase substantially the speed ratio model of variable speed
It encloses, passes through fuel-economy when engine operation.
