State the diameter of the second driving wheel;Brake is provided between the outer gear ring and shell of the planetary gear train;The power input
Axis and/or power output shaft are connected to the speed change gear by second clutch.
Using the above structure, since planetary gear train can be with respect to power input shaft unitary rotation, and power input shaft can
Motor and shell are rotationally passed through, second clutch is disconnected, so that it may which pure motor driven is realized in the power input for cutting off engine
Mode, under this drive mode, in conjunction with first clutch, breakaway braking device, it will be able to the first driving wheel and the second driving wheel
Between reduction ratio carry out primary speed-down output;In conjunction with brake, first clutch is disconnected, it will be able to subtracting for planetary gear train
The product of reduction ratio between speed ratio and the first driving wheel and the second driving wheel carries out double reduction output.In this way, realizing pure
Motor-driven two stage speed change advantageously reduces power of motor, while ensuring that motor efficiently exports.And in pure engine driving mould
Under formula, engine direct tape splicing moves speed change gear, and the rotor and power input shaft of motor relatively rotate, so as to avoid motor from turning
Weak magnetic loss of torque when son idle running, is conducive to improve the delivery efficiency under pure engine 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, improves engine fuel economy.
Further, first driving wheel and the second driving wheel are sprocket wheel, and are connected by chain.
Further, the speed reducer assembly being meshed with the second driving wheel is also equipped in the shell;The retarder
Assembly includes speed reducing input and differential mechanism, has the first gear being meshed with the second driving wheel on the speed reducing input,
Also there is the second gear being meshed with the input gear of the differential mechanism on the speed reducing input.
In conclusion the utility model have it is reasonable in design, be suitable for multiple drive modes, transmission efficiency it is high etc.
Advantage.
