Description
Technical field
The present invention relates to electric assisted bicycle technical field, particularly relate to a kind of bicycle use built-in motor.
Background technology
Electric assisted bicycle refers on the basis of ordinary bicycle, is provided with the parts such as motor, controller, and with electricity
Pond is as the Personal Transporter of supplementary energy.In use, cyclist still presses the side of standard bicycle to electric assisted bicycle
Formula cycles, and is provided power-assisted by motor, simultaneously the big I of the power-assisted of motor by controller automatically according to the situation of riding of cyclist
It is adjusted.
Wherein, the motor type that electric assisted bicycle uses can be divided into built-in motor and wheel hub motor two kinds, the former
It is that motor is arranged at bicycle middle shaft position, i.e. bicycle pedals, and passes through actuating device by power transmission to trailing wheel；After
Person is to be directly installed on by motor on front axle or hind axle, i.e. eliminates actuating device, and power transmission is directly given front by motor
Wheel or trailing wheel.Specifically, the bicycle of built-in motor is used can be placed in by motor in terms of complete vehicle weight distribution the most reasonable
Middle part, effectively prevent use wheel hub motor bicycle turn time cause due to crank dangerous because of
Element, thus safety when being effectively increased complete vehicle structure and ride；Further, when dead battery, the electricity of built-in motor is used
Dynamic moped can be ridden as ordinary bicycle, it is possible to is 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.
Further, above-mentioned bicycle use built-in motor generally uses the reducing motor of motor acceleration and deceleration mechanism, and
And structurally can be divided into two classes: concentric shafts structure and parallel axle construction；Concentric shafts structure refers in motor shaft and bicycle
Axle uses the mode of concentric co-axial；Parallel axes structure refers to that motor shaft is provided separately within the position parallel with bicycle middle shaft.
In actual 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, uses built-in motor many employings planetary gear reducing mechanism of concentric shafts structure, so that the overall structure of motor is more
Add small and exquisite, take up room the most less；Use built-in motor many employings cylindrical gear reducer structure of parallel axes structure, can pass through
Multiple stage gear reduction obtains bigger speed reducing ratio, so that the rotating speed of motor is higher.
But, present inventor finds, the built-in motor of concentric shafts structure is owing 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 causes the performance of motor to fill
Distribution is waved；The built-in motor of parallel axes structure, owing to using multistage cylindrical gear reducer structure, is therefore easily caused the body of motor
Long-pending relatively big, entirety is heavier.
Therefore, how the bicycle use built-in motor that a kind of compact conformation, small volume and rotating speed are higher is provided, it has also become
Those skilled in the art need badly and solve the technical problem that.
