Abstract

The utility model discloses an electric bike which is driven by the front wheel, which is designed to solve the problem of the prior electric bike which has unsteady gravity center and unbalance power assemble. The utility model comprises a motor which is connected with the power and a front wheel which is positioned in the front fork of the bike; the motor is fixed in one side of the front fork of the bike; the rotating axis of the motor is provided with a transmission gear; the center of the front wheel is still provided with a driving gear; and a transmission component connects the transmission gear with the driving gear. The utility model has the advantages of steady gravity center and balanced power assembly.

Description

The Electrical Bicycle of f-w-d

Technical field:

The utility model relates to a kind of Electrical Bicycle, particularly a kind of Electrical Bicycle of f-w-d.

Background technology:

The Electrical Bicycle kind of selling on the market is more now, and what its electric drive part had is arranged on the trailing wheel, directly drives the trailing wheel rotating shaft and rotates; The electric drive part that has is arranged on the bicycle pedals wheel shaft, drives pedal wheel by electric drive part, drives trailing wheel then and rotates; The Electrical Bicycle of above-mentioned two kinds of structures all only has back-wheel drive in motion, and it is slow to exist uphill way to walk, the problem of under power on sand ground; And electric drive part is arranged at trailing wheel, also has the problem after whole bicycle center of gravity is leaned on.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of barycentre steadiness is provided, the Electrical Bicycle of the f-w-d of power configuration balance.

For achieving the above object, the utility model adopts following technical scheme: the Electrical Bicycle of this f-w-d, comprise and power supply bonded assembly electrical motor and the front vehicle wheel that is arranged on the bicycle front fork, described electrical motor is fixedly arranged on a side of bicycle front fork, on the turning cylinder of electrical motor, transmission gear is housed, at driven wheel of the center of front vehicle wheel rigidity assembling, a Transmission links together transmission gear and driven wheel.

The electrical motor of the Electrical Bicycle of the utility model f-w-d is arranged at the bicycle front-wheel, make bicycle barycentre steadiness in the process of moving, again because the Electrical Bicycle of this f-w-d drives bicycle running by the driven by power front-wheel, can rely on manpower to drive trailing wheel simultaneously where necessary, increase the power of bicycle, reach the purpose of power configuration balance.

Description of drawings:

Fig. 1 is the block diagram of the Electrical Bicycle of the utility model f-w-d

Fig. 2 is the exploded drawings of the Electrical Bicycle of f-w-d shown in Figure 1

The specific embodiment:

As shown in Figure 1 and Figure 2, the Electrical Bicycle of the utility model f-w-d comprises following structure:

Bicycle 10 with bicycle front fork 11, the crossbeam of bicycle 10 are provided with a box 14, are placed with power supply 15 in box 14.

An electrical motor 20, electrical motor 20 are fixedly arranged on a side of bicycle front fork 11, and electrical motor 20 is electrically connected with power supply 15, and transmission gear 21 is housed on the turning cylinder of electrical motor 20.

A front vehicle wheel 40 has a unilateral bearing 33 at the central mounting of front vehicle wheel 40, is fixed with a driven wheel 30 on unilateral bearing 33 outer rims, and driven wheel 30 also is assemblied in the center of front-wheel 40 when direct rigidity certainly.

A Transmission 50 links together transmission gear 21 and driven wheel 33, and Transmission 50 can be chain or odontoid belt, is odontoid belt in the present embodiment.

The utility model in use, power supply 15 makes electrical motor 20 rotation, drives transmission gear 21, driven wheel 30 rotates, and drives bicycle front wheel 40 and rotates.

The Electrical Bicycle of the utility model f-w-d has following advantage:

1. electrical motor of the present utility model and transmission device are arranged at the front-wheel of bicycle, advance with Frontwheel driven bicycle, increase power but manpower drives trailing wheel where necessary to bicycle, the bicycle of this spline structure can not walked slow at uphill way, or at the sand ground under power.

2. electrical motor of the present utility model and transmission device are arranged at the front-wheel of bicycle, and the situation that can make former bicycle center of gravity fall within trailing wheel improves, and makes the forward and backward counterweight unanimity of bicycle; The excessive situation of bicycle rear crust wearing and tearing can not appear.

3. of the present utility model simple in structure, applicability is strong; Can be applicable to the bicycle of any model.

Claims
