Abstract
The utility model relates to an electric driving device for a bike comprising a motor assembly and a driven wheel disc. The motor assembly is directly positioned on a permanent seat of the bike front fork brake. The motor assembly is composed of a motor and a driving wheel disc driven by the motor. The driven wheel disc is positioned on the permanent seat of the disc brake at the outer side of the axis of the front bike axis and formed a transmission connection with the driving wheel disc. The driving wheel disc and the driven wheel disc are gears mutually engaged. The driving wheel disc is a gear wheel and the driven wheel disc is a ring gear disc. The gear is engaged with the inner teeth of the ring gear disc. The motor assembly also concludes a speed-reducing device. The utility model is simple in the structure, easy in the installment and convenient to face-lift the prior bike as an electric bike, drastically reducing the economic burden for the customer.
Description
Technical field
The utility model relates to a kind of bicycle driving device, is meant a kind of bicycle electric actuating device especially.
Background technology
License, zero pollutes, zero noise because bicycle need not refuel, not need, and structure is light, therefore be always in, one of the vehicle of short distance working clan's favor.Yet standard bicycle mainly relies on manpower to trample onward impulse is provided, and when reality is used, often because of the influence that is subjected to muscle power, road conditions and drives factors such as distance, and allows the people feel painstakingly, must transfer to other the vehicle even; Therefore, the Electrical Bicycle of motorized motions function promptly appears having in industry, allows the rider can utilize electro-motor as auxiliary power where necessary, to reduce the consumption of muscle power.
But, this type of Electrical Bicycle mainly combines with the car body of bicycle by the specially designed driving device of process, that is: use exclusive transmission design to make the power of motor can be transferred to the sprocket wheel or the wheel of bicycle, make that the modification difficulty of Electrical Bicycle is higher, and do not conform to economic benefit, at present, existing common electric bicycle mostly is the specific manufacturing of manufacturer, the exclusive Electrical Bicycle that sells, for generally being dependent on the customer of bicycle as walking-replacing tool, buying more one one again has electronic auxiliary bicycle in addition if want, and is again a no small burden undoubtedly.
The utility model content
Technical problem to be solved in the utility model is: a kind of bicycle electric actuating device is provided, and it is simple and practical, can be easily with existing bicycle repacking becoming Electrical Bicycle.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bicycle electric actuating device comprises a motor assembly and a driven wheel disc.Described motor assembly directly is installed on the bicycle front fork brake permanent seat, and motor assembly comprises motor and the active wheel disc that is turned by motor; Described driven wheel disc is installed on the disc brake dish permanent seat of wheel shaft outer end of bicycle front-wheel, and constitutes driving coupling with the active wheel disc of motor assembly.
Further improvement in the technical proposal is: this active wheel disc and driven wheel disc are respectively pitch wheel.
Further improvement in the technical proposal is: this active wheel disc is a gear, and driven wheel disc is an annular fluted disc, the internal gearing of described gear and annular fluted disc
Further improvement in the technical proposal is: this motor assembly also comprises a speed reduction gearing.
The utlity model has following beneficial effect: motor assembly of the present utility model can directly be installed on the brake permanent seat of bicycle front fork, and driven wheel disc can be installed on the disc brake dish permanent seat of wheel shaft outer end of bicycle front-wheel, and constitute driving coupling with the active wheel disc of motor assembly, thereby can provide assistive drive power by motor assembly, the utility model is simple and practical, and it is easy for installation, can easily existing bicycle repacking be become Electrical Bicycle, significantly reduce customer's economical burden.
Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment
As shown in Figures 1 and 2, the utility model provides a kind of bicycle electric actuating device, comprises a motor assembly 10 and a driven wheel disc 20.
Wherein, motor assembly 10 comprises that a motor 11, an active wheel disc 12 that is turned by motor 11 reach the motor fixing base 13 that directly is installed in bicycle front fork 30 brake permanent seats 31, described motor fixing base 13 utilizes connecting element 50 to be installed on the brake permanent seat 31, and motor 11 also utilizes connecting element 50 to be fixed on the motor fixing base 13.
And driven wheel disc 20 is installed on the disc brake dish permanent seat 42 of wheel shaft 41 outer ends of bicycle front-wheel 40, and constitutes driving coupling with the active wheel disc 12 of motor assembly 10.
In the specific implementation, initiatively wheel disc 12 and driven wheel disc 20 can constitute as Fig. 1 and gear shown in Figure 3, under the external tooth of active wheel disc 12 and driven wheel disc 20 is meshing with each other, and the driving coupling of formation integral electric actuating device and bicycle front-wheel, can drive front-wheel 40 rotations of bicycle where necessary by the motor in the middle of the motor assembly 10 11, allow first obtain auxiliary power voluntarily.
In addition, gear (initiatively wheel disc 12) and annular fluted disc (driven wheel disc 20) shown in initiatively wheel disc 12 also can be worked as by Fig. 4 and Fig. 5 respectively with driven wheel disc 20 are constituted, under the internal tooth of the external tooth of active wheel disc 12 and driven wheel disc 20 is meshing with each other, can constitute the driving coupling of integral electric actuating device and bicycle front-wheel equally.
The utility model Vidacare corp can directly be installed at bicycle front-wheel place, and the person of being easy to use becomes Electrical Bicycle with existing bicycle repacking, significantly reduces customer's economical burden; In addition, motor assembly 10 also can further comprise a speed reduction gearing, to promote the transmission torsion of whole actuating device.
