Description

Front-wheel traction Electrical Bicycle

One, technical field

The utility model relates to a kind of Electrical Bicycle, particularly a kind of Electrical Bicycle of front-wheel traction.

Two, background technology

Present Electrical Bicycle generally adopts disc type electric machine, back-wheel drive, has advantages such as the speed of a motor vehicle is moderate, stable, the zero-emission of riding, energy utilization rate height, economic operating cost, and liking of consumers in general extremely, and the support of governments at all levels and help.But the back-wheel drive Electrical Bicycle also exists the some shortcomings part, the one, and complex structure, working accuracy and assembling quality requirement height cause factory's manufacturing cost high; The 2nd, break down the inspection and maintenance inconvenience; The 3rd, the front and back wheel load-bearing is inhomogeneous, causes that easily trailing wheel damages; The 4th, resistance is big during with foot pedal apparatus, and is heavy more many than ordinary bicycle.

Three, summary of the invention

In order to overcome the disadvantage of existing electric bicycle structure complexity, manufacturing cost height, inconvenient maintenance, the utility model provides a kind of front-wheel simple and reasonable, easy to use and reliable, easy to maintenance, that cost is low to draw Electrical Bicycle.The technical scheme that its technical matters that solves the utility model adopts comprises car body, handle, foot pedal apparatus, be arranged on front-wheel and trailing wheel on the car body, be fixed on storage battery, controller on the car body, be fixed with motor on the front fork of described car body, the axis of described front-wheel is provided with flywheel, flywheel is provided with sprocket wheel, connects by messenger chain between motor and the sprocket wheel.

After adopting said structure, motor can adopt common DC motor, directly drives the front-wheel operation by messenger chain, sprocket wheel and flywheel, when with foot pedal apparatus by bike the time and ordinary bicycle be consistent; Have simple and reasonable, cost is low, assembling and easy to maintenance, steady quality, efficient advantages of higher.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Five, the specific embodiment

Shown in Figure 1, specific embodiments for the utility model front-wheel traction Electrical Bicycle, it comprises car body 1, handle, foot pedal apparatus, be arranged on front-wheel 7 and trailing wheel on the car body 1, be fixed on storage battery, controller on the car body 1, be fixed with motor 2 on the front fork 3 of described car body 1, the axis of described front-wheel 7 is provided with flywheel 6, flywheel 6 is provided with sprocket wheel 5, connects by messenger chain 4 between motor 2 and the sprocket wheel 5.After adopting above form, the front and rear wheel load-bearing is tended to balance; Motor 2 usefulness common DC motors replace disc type electric machine, and not only making convenient, quality can guarantee, and price can descend significantly, only need 1/5 of former price.

During use, by being arranged on storage battery, controller and 2 operations of speed-regulating handle bar hand shift motor on the car body 1, motor 2 drives sprocket wheel 5 by messenger chain 4, and sprocket wheel 5 drives front-wheel 7 by flywheel 6 and rolls, thereby realizes the function of electric traction.When employing was ridden by bike, its function was fully the same with bicycle, is driven by trailing wheel, and motor 2 is not worked, and front-wheel 7 separates with motor driver by flywheel 6.Certainly, the utility model can also adopt foot pedal apparatus to carry out power-assisted, particularly at the regular meeting's foot pedal apparatus often of climbing in motor 2 tractions.

Claims (1)

1, a kind of front-wheel traction Electrical Bicycle, it comprises car body (1), handle, foot pedal apparatus, be arranged on front-wheel (7) and trailing wheel on the car body (1), be fixed on storage battery, controller on the car body (1), it is characterized in that: be fixed with motor (2) on the front fork (3) of described car body (1), the axis of described front-wheel (7) is provided with flywheel (6), and flywheel (6) is provided with sprocket wheel (5), connects by messenger chain (4) between motor (2) and the sprocket wheel (5).
