Embodiment Construction

[0056] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0057] figure 1 It is a schematic diagram showing the electric assist bicycle 1 according to the first embodiment of the present invention. As shown in the figure, the main frame of the electric power-assisted bicycle 1 is the same as that of an ordinary bicycle, and is composed of a metal tube frame 3 on which a front wheel 20, a rear wheel 22, a handle are mounted in a well-known manner. 16 and car seat 18 etc.

[0058]Further, a drive shaft 4 is rotatably supported at the center lower portion of the frame 3 , and pedals 8L, 8R are attached to both left and right ends of the pedals 8L, 8R via crank rods 6L, 6R, respectively. On the drive shaft 4, via a one-way clutch (described later image 3 (99) of (b) coaxially attaches the sprocket 2, and this one-way clutch transmits only the rotation in the R direction corresponding to the forward direc...

Abstract

The invention provides an electric power assisted bicycle and an assembly suitable for the electric power assisted bicycle and capable of being mounted on a bicycle frame. The assembly not only can simplify an auxiliary power mechanism used for the electric power assisted bicycle but also can be easily mounted on the bicycle frame. The assembly is characterized in that at least the following components are arranged on a common base to form the assembly: a chain wheel, an electric power output mechanism, an auxiliary gear, a connecting mechanism and a drive shaft, wherein the chain wheel is used for transmitting pedaling force to a drive wheel and can rotate; the electric power output mechanism outputs electric power used for assisting the pedaling force through an output shaft; the auxiliary gear is connected with the output shaft of the electric power output mechanism through a gear mechanism; the connecting mechanism connects the auxiliary gear with the chain wheel coaxially; the drive shaft is stored in a shaft sleeve in a rotating mode by utilizing the pedaling force; the shaft sleeve is connected with the common base, or the shaft sleeve and the common base are formed integrally.

Description

[0001] The applicants of this application are New Era Technical Research Co., Ltd. and New Era Engineering Co., Ltd., and the application date is March 28, 2007. The title of the invention is "electric power-assisted bicycles and components for electric power-assisted bicycles that can be installed on bicycle frames". A divisional application of the invention patent application with application number 200780052287.0. technical field [0002] The present invention relates to an electric assist bicycle capable of running by assisting pedaling force with electric power, and an electric assist bicycle assembly which can be mounted on the bicycle frame. Background technique [0003] Generally, an electric assist bicycle capable of traveling by assisting pedaling force with electric power is provided with a synthesizing mechanism for synthesizing pedaling force and electric power. As an example of such a combined force mechanism, an electric assist bicycle having the combined forc...
