New description: [New technical field] The belt-type bicycle of this creation is mainly used for the labor-saving technology when the car is stepping on. [Prior Art] According to the conventional bicycle, the transmission wheel is round. Since the transmission wheel is in a circular rotation state when the pedal is stepped on, the force that can help the rotation of the transmission wheel cannot be generated, so it is quite laborious when stepping on the pedal. It is still waiting for # to overcome the problems and problems solved. [New Content] The creator is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. In response to the current hard-working questions, problems and shortcomings of bicycle pedaling, he actively invested in the spirit of innovation and improvement. The transmission structure of the belt bicycle. The technical means applied by the new problem solving and the effect of the prior art are that the outer side of the driving wheel of the bicycle is provided with a concentric convex _ wheel of the same center. When the pedal is stepped on, the circular driving wheel rotates, and the elliptical cam It will also follow the rotation. Because the elliptical cam rotates, it will produce inertia, so it can help the transmission wheel to rotate and achieve the goal of labor saving. [Embodiment] In order to make it easier for those skilled in the art to understand the art to understand the construction content of the creation and the functional benefits that can be achieved, a specific embodiment will be listed and described in detail as follows: For the transmission structure of the bicycle, please refer to the first and second figure 4 M305170. · The three-dimensional combination and three-dimensional decomposition diagram of the creation. As shown in the third figure: a schematic diagram of the solution of the solution. And the schematic diagram of the p-p section of the third figure. Mainly in the bicycle shaft 1 of the bicycle, the transmission wheel i 2 is provided on the side 1 , the two ends of the transmission shaft i W are provided with two cranks 13 , and the two cranks 13 are provided with the foot pedals 14 in the upper-lower configuration. 'The inside of the drive wheel 12 is provided with teeth! 5, as the father of the transmission belt worker 6 'to transfer the rotational force of the transmission wheel 12 to the rear wheel 17 of the bicycle 10, so that the bicycle 1〇; characterized in that: the outer side of the transmission wheel 12 is provided with a concentric ellipse The shape of the cam is 8 The combination of the above-mentioned various component structures is based on the provision of a belt-type bicycle. In practical applications: Please refer to the fifth and sixth riding instructions: the pedaling state of this (four) Schematic two two. And the seventh, eighth, ninth, and tenth pictures are shown in the first, second, third, and fourth diagrams of the treading state of the creation. When the foot pedal 14 is stepped on, the transmission wheel 12 will drive the elliptical cam 18 to rotate, and the inertial torsional force will be generated when the elliptical cam 18 rotates, thereby helping the transmission wheel 12 to continue to rotate, and the pedal can be more labor-saving when pedaling. the goal of. In summary of the above-mentioned creation, the transmission structure of the belt-type bicycle is provided. After the actual production of the creator completes the money and the operation test proves that the functional benefits of the creation can be achieved, and at the same time, there is no such thing as the current experience. The "first creation" has "industry use value", and it has already met the requirements of the establishment of the "patentability" and "progressiveness" of the new patents, and has filed a new patent application with the bureau in accordance with the provisions of the Patent Law.
