Abstract
The utility model discloses a front-drive electric bicycle which includes a frame, a power source, a front fork, a front wheel, a rear wheel and a foot pedal; the shafts of the front wheel and the rear wheel are provided with flywheels which drive the two to rotate; a motor is arranged on the upper side of the front wheel by a bracket; the motor is electrically connected with the power and is connected with the chain of the flywheel which drives the front wheel by a drive chain wheel on the shaft of the motor; the flywheel driving the rear wheel is connected with the chain wheel on the shaft of the foot pedal by a chain. In the electric bicycle, manual drive is realized by driving the flywheel on the rear wheel by the foot pedal; while electric drive is realized by driving the flywheel on the front wheel by the motor. During manual drive, the flywheel on the front wheel is in a relatively static state which can not drive the shaft of the motor to rotate, thereby being incapable of generating electromagnetic resistance, thus being not hard to drive.
Description
Technical field
The utility model relates to the vehicle, is specifically related to a kind of front-driving electric bicycle.
Background technology
As everyone knows, bicycle as the vehicle of environmental protection just by a large amount of uses.Electrical Bicycle has been come into huge numbers of families as the upgrading products of bicycle.The Electrical Bicycle of Xiao Shouing in the market, all be the rear-guard formula mostly, this kind rear-guard formula Electrical Bicycle adopts the direct current permanent magnetic motor, motor is an outer-rotor type, the shell that is motor is a rotor, and the mandrel that connects to ground is a stator, and the shell of motor is that rotor and back wheels of vehicle link together, flywheel and rotor link together, and flywheel is connected with sprocket wheel on the pedal axle by chain.This Electrical Bicycle can be rotated by the motor-driven trailing wheel, also can drive trailing wheel by manpower and rotate, and promptly drives flywheel by pedal, and flywheel drives rotor, and rotor drives trailing wheel and rotates.This Electrical Bicycle adopts motor and two kinds of modes of manpower to drive, use more convenient, but, because the rotor and the back wheels of vehicle of motor link together, flywheel and rotor link together, when manpower drives, rotor is that stator rotates around motor mandrel under the drive of flywheel, winding cutting magnetic line in the motor produces electric current, thereby produces oppositely directed electromagnetic torque, so manpower drives very effort.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of manpower to drive effortless front-driving electric bicycle at above-mentioned defective.
For solving the problems of the technologies described above, the utility model provides a kind of front-driving electric bicycle of following structure, comprise vehicle frame, power supply, front fork, front-wheel, trailing wheel and pedal, its constructional feature is: on the axle of described front-wheel and trailing wheel the flywheel that drives the two rotation is housed, motor is installed in the top of front-wheel by support, motor and power supply are electrically connected and are connected with the flywheel chain that drives front-wheel by the drive sprocket on it, the flywheel of driving trailing wheel be contained in pedal spool on sprocket wheel be connected by chain.
The Electrical Bicycle of said structure, manpower driving are to realize by the flywheel that pedal drives on the trailing wheel, and driven by power is to realize by the flywheel on the motor-driven front-wheel.When manpower drove, speed was slower, and the flywheel on the front-wheel is in relative static conditions, can not drive motor shaft and rotate, thereby can not produce electromagnetic resistance, therefore, can save muscle power, drove not too effort.
In order to make motor more firm and be convenient to motor year with front-wheel steering, described support is connected on the axle of front fork and front-wheel.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Front-driving electric bicycle as shown in drawings is by comprising vehicle frame 1, power supply 2, front fork 3, front-wheel 4, trailing wheel 5, handlebar 12, pedal 6 and vehicle seat 11.The trailing wheel 5 of the band flywheel 7 identical with the structure of existing common two-wheeled cycle is equipped with at the rear portion of vehicle frame 1, and the flywheel 7 on the trailing wheel 5 links together by the sprocket wheel on the axle of chain and pedal 6.The top, middle part of vehicle frame 1 is provided with vehicle seat 11, and the below of vehicle seat 11 is provided with power supply 2.The front portion of vehicle frame 1 is connected with front fork 3, and the top of front fork 3 is connected with handlebar 12, and the bottom of front fork 3 is connected with identical front-wheel 4 with trailing wheel 5 structures, also is provided with flywheel 7 on the front-wheel 4.Be connected with support 10 on the axle of front fork 3 and front-wheel 4, motor 8 is installed on the support 10, and the axle of motor 8 is provided with drive sprocket 9, is connected with driving chain on the flywheel 7 of drive sprocket 9 and front-wheel 4.Motor 8 forms with power supply 2 and is electrically connected.
The essence that realizes the technical scheme of the utility model front-driving electric bicycle is, its front and rear wheel all adopts the trailing wheel that has flywheel of common two-wheeled cycle, the type of drive of the trailing wheel of Electrical Bicycle is identical with ordinary bicycle, and the driving of the front-wheel of Electrical Bicycle is finished by the motor that is located at the front-wheel top.
