Problems solved by technology

[0003] In order to overcome the shortcomings of the existing electric bicycles, such as excessively high power, inconvenient riding, and short driving distance, the present invention aims to provide an electric bicycle with a composite wheel structure. According to the principle of wheel kinematics, the electric bicycle The goal of vehicle energy saving can be achieved by reducing the radius size, reducing the radius size of the driving wheel and rationally distributing the power

Embodiment Construction

[0039] see figure 1 , the rear axle of the composite wheel is composed of a power transmission shaft 5, a fixed bushing 4 and a wheel hub bushing (bicycle wheel faceplate) 3 three-layer structure, of which:

[0040] The fixed bushing 4 is used to provide the function of connecting and fixing the composite wheel and the vehicle frame, and this part is a non-moving part;

[0041] The power transmission shaft 5 is connected to the fixed bushing 4 via a bearing, and is used to provide circumferential torque to the drive wheel (non-load wheel) 2 in the composite wheel, which is a moving part;

[0042] The wheel hub bushing (bicycle wheel faceplate) 3 is connected to the outer layer of the fixed bushing 4 via a bearing, and is used for the setting of the load wheel in the compound wheel, and this part is a moving part.

[0043] see figure 2 , the load wheel 1 is fixed in the composite wheel rear axle system through the wheel hub bushing (bicycle wheel faceplate) 3, and becomes th...

Abstract

The invention discloses an electric bicycle with a combined wheel structure, aiming to solve the problems that the existing electric bicycle is obviously over high in power, inconvenient to ride and short in driving distance. The electric bicycle with the combined wheel structure comprises a combined wheel which is arranged on the wheel shaft part of a frame and is formed by combining a loading wheel, a driving wheel, a wheel hub shaft sleeve, a fixing shaft sleeve and a power transmission shaft; the power transmission shaft is arranged on the back wheel part of the frame and the power transmission shaft is provided with the fixing shaft sleeve; the fixing shaft sleeve is provided with a driving wheel bracket and the wheel hub shaft sleeve; the driving wheel bracket is provided with the driving wheel; the wheel hub shaft sleeve is provided with the loading wheel; one side of the driving wheel is provided with a driving head which is fixedly connected with the driving wheel; the driving head is connected with the power output of the motor; and the radius of the driving wheel is more than or equal to one half of the loading wheel. By using the electric bicycle with the combined wheel structure, the target that the driving force of a vehicle is greatly improved on the premise that the motive power configuration of the vehicle is not increased is realized.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to an electric bicycle with a compound wheel structure. Background technique [0002] Currently widely used electric bicycles adopt the structure of wheel driven wheel and driving wheel. The wheel that is about to rely on the torque transmitted to the circumference of the wheel is called the driving wheel, and the wheel that relies on the thrust of the center of the wheel is called the driven wheel; the driving wheel also bears the load of the vehicle. . The principle of classical wheel kinematics reveals that in this traditional wheel system structure, the larger the radius of the driven wheel, the smaller the required thrust, and the smaller the radius of the driving wheel, the greater the driving force; in addition, the wheel drive wheel adopts the hub type Driven by a DC motor, coaxial with the human-powered drive, resulting in labor-intensive conditions when riding manually. In practi...
