Description
Technical field
This utility model is related to electric assisted bicycle technical field, more particularly, to a kind of bicycle use built-in motor.
Background technology
Electric assisted bicycle refers to, on the basis of ordinary bicycle, be provided with the parts such as motor, controller, and with electricity
Pond is as the Personal Transporter of supplementary energy.When using, cyclist still presses the side of standard bicycle to electric assisted bicycle
Formula cycles, and provides power-assisted by motor, simultaneously the big I of the power-assisted of motor by controller automatically according to cyclist situation of riding
It is adjusted.
Wherein, the motor type that electric assisted bicycle uses can be divided into built-in motor and two kinds of wheel hub motor, the former
It is that motor is arranged on bicycle middle shaft position, that is, at bicycle pedals, and pass through actuating device by power transmission to trailing wheel；Afterwards
Person is that motor is directly installed on front axle or hind axle, that is, eliminate actuating device, and power transmission is directly given front by motor
Wheel or trailing wheel.Specifically, in terms of complete vehicle weight distribution, motor can be placed in using the bicycle of built-in motor the most reasonable
Middle part, effectively prevent that the bicycle using wheel hub motor caused due to crank when turning dangerous because
Element, thus safety when effectively increasing complete vehicle structure and riding；And, when dead battery, using the electricity of built-in motor
Dynamic moped can be ridden as ordinary bicycle, can be prevented effectively from wheel hub motor electricity when front-wheel (or trailing wheel) operates
The additional drag that machine coil cutting magnetic line is brought.

And two classes: axle construction peace row axle construction with one heart can be divided in structure；Axle construction refers in motor shaft and bicycle with one heart
Axle is by the way of concentric co-axial；Parallel axle construction refers to that motor shaft is provided separately within the position parallel with bicycle middle shaft.
In practical application, in order to ensure the gait of march of electric assisted bicycle, it usually needs by built-in motor, speed reducing ratio is carried out
Reasonable disposition, using adopting planetary gear reducing mechanism the built-in motor of concentric axle construction, so that the overall structure of motor is more more
Plus compact, take up room also less；Adopt cylindrical gear reducer structure using the built-in motor of parallel axle construction more, can pass through
Multiple stage gear reduction obtains larger speed reducing ratio, so that the rotating speed of motor is higher.
However, present inventor finds, the built-in motor of concentric axle construction is due to being slowed down by planetary gear reducing mechanism
The relatively low restriction of ratio, the rotating speed being therefore easily caused motor is relatively low, power density is less, thus causing the performance of motor cannot fill
Distribution is waved；The built-in motor of parallel axle construction is due to using multistage cylindrical gear reducer structure, being therefore easily caused the body of motor
Long-pending larger, overall heavier.
Therefore, how a kind of compact conformation, small volume and the higher bicycle use built-in motor of rotating speed are provided, it has also become
The technical problem of those skilled in the art's urgent need to resolve.
