Description
Technical field
The present invention relates to a kind of for electric bicycle, the driving means of the compound speedup of electrically assisted bicycle.
Background technology
It is fairly common a kind of vehicles in today's society that electric bicycle is also battery-operated motor cycle, though moulding is each
It is different, but agent structure and function are substantially similar.Typically all existed using the control electric unit drive installation of battery Jing control systems
Motor in rear-wheel hub, then trailing wheel is driven Jing after The gear deceleration, the electric energy of battery is the major impetus source of electric bicycle.
Wherein, flywheel is additionally provided with the hind axle of part electric bicycle and corresponding pedal and chain drive is equipped with, when manpower is stepped on
When stepping on the speed of pedal-driven flywheel more than motor-driven speed, foot-operated driving can be played a part of power-assisted and accelerate.But,
As the actual design and the speed of service of electric bicycle are higher than the speed of ordinary bicycle, and the deadweight of electric bicycle itself
Also greater than bicycle, therefore, the speed that the pure manpower of electric bicycle of correspondence design is ridden is lower than ordinary bicycle.So,
Even if part electric bicycle is provided with assisted pedal stroke function, it is actually used during also only in starting and accumulator electric-quantity
Not enough grade is in particular cases worked, and it be also that sky is stepped on to step in the case of other, it is impossible to realize manpower with electronic composite flooding.
In addition, also using electric boosted bicycle on market, that is, increase a set of micro electric drive on bicycle
Dynamic device, rides the torsion of pushes pedals by real-time detection people and speed provides power-assisted moderately and at the right moment, with alleviate upward slope,
Demand during acceleration etc. to manpower, realization are steadily ridden.Riding speed of the speed of bicycle operation depending on the people that rides,
Powered part reinforcement not speedup.And if increase the power of powered part output, simply further reduce manpower, its function and effect
Foregoing electric bicycle is equal to again.
Therefore, either existing electric bicycle or electric assisted bicycle, do not realize well it is electronic and
The fusion that manpower is ridden, further to reach the effect of energy-conserving and environment-protective.Its main cause is existing driving principle and structure
The simply mutual power-assisted realized, without realizing the compound increase of both speed.
The content of the invention
In view of the deficiency that aforementioned existing electric bicycle and electric assisted bicycle are present, the present invention provides a kind of electronic
The compound speedup driving means of bicycle, which can effectively solving disadvantages mentioned above.
For reaching above-mentioned goal of the invention, the technology used in the present invention means increase for a kind of electric bicycle of design is compound
Fast driving means, wherein include：
One housing, is internally provided with planet carrier；
One motor, comprising rotor and stator；
One left plate and a right plate, are separately fixed at housing two ends；
Multiple planetary gears, are uniformly arranged on the planet carrier of enclosure interior by planet wheel spindle and bearing respectively；
One sun wheel shaft, its one end are provided with central gear and are meshed with each planetary gear, the rotor of other end and motor
It is connected, and by bearings in housing；
One input gear ring, which is arranged central gear, and is meshed with each planetary gear, with central gear and each planetary gear
Planetary gearsets are combined into together；It is described to be input into the axially extended left plate in gear ring one end and be connected with flywheel；
One support shaft, which is concentric to be arranged in housing, left plate, input gear ring, sun wheel shaft, motor, right plate, and
It is connected with the stator of motor；
One freewheel clutch, which is arranged between input gear ring and support shaft, to ensure to be input into gear ring relative support axle
Can only one-directional rotation.
It is an advantage of the current invention that the housing being fixedly connected with spoke is provided with electric bicycle driving wheel hub central authorities,
Case inside planet gripper shoe is provided with planet carrier, and multiple planetary gears are housed on planet carrier；Each planetary gear respectively with the sun
The central gear of wheel shaft one end is meshed, and the other end of sun wheel shaft is fixedly connected with the rotor of motor；Central gear periphery set
Input gear ring is provided with, and is fixed with the gear ring axle of input gear ring side and unidirectional delivery chain is similarly used for ordinary bicycle flywheel
Bar drives the flywheel of power；Input gear ring is meshed with each planetary gear respectively, and is combined into row with central gear, planetary gear
Star gear train.According to Gear Planet Transmission principle, the rotating speed of the planet carrier being fixedly connected with driving wheel is depending on being connected with rotor
The speed of the input gear ring that the rotating speed and Jing chains of central gear, flywheel drive, that is to say, that electric bicycle driving wheel
Rotating speed depends on motor speed and Speed of Reaction Wheels.It is thereby achieved that two-way drives the compound speedup of power.
Additionally, be respectively provided on two sides with the housing being mutually fixedly connected with electric bicycle driving wheel spoke to be secured to be connected
Left plate and right plate, its axle center is provided with support shaft, left plate and right plate respectively by bearings input gear ring and
On support axle, make entirely to be combined the wheel hub that speedup driving means form a closing in the middle of driving wheel.And support shaft two ends are fixed on
On electric bicycle fame.Therefore, the present invention design compound speedup driving means contour structures or mounting means all with
Existing electric bicycle and its driving wheel are consistent, and its application will not change the overall structure and control method of existing electric bicycle.
Furthermore, freewheel clutch is provided between input gear ring and support shaft, can prevent from not providing driving force when chain
Or in the case of brake force, Jing sun wheel shafts, planetary gear are driven input gear ring and flywheel idle running so as to can not by rotor
Driving wheel is driven to advance.Therefore, the present invention maintains the pure electric drive mode of existing electric bicycle.
Finally, sun wheel shaft and input gear ring are respectively by bearings in enclosure interior planet gripper shoe and left plate
On, Gear Planet Transmission is effectively ensured three-element axially mounted and fixed.Meanwhile, the radial dimension of central gear is reduced, is had
Beneficial to increase planetary drive ratio, motor is improved to the speed reducing ratio of driving wheel.And bearing rotating speed is effectively reduced, so as to reduce
Demand of the bearing to lubrication.
