Description

V. Description of the invention (1) "Overview of the invention" The present invention is a "bicycle automatic internal transmission system J, especially a transmission system installed in a flower compared to the interior", which makes the effect of lubrication and sealing better, but not easy It is damaged by external interference, and it is driven by a belt as a whole. It is easy to assemble, low noise, no additional lubrication is required, and can allow large combined tolerances. The functions of step-shifting and automatic shifting are for users who can adjust the input torque appropriately according to their own preferences. "Background of the Invention" Among the bicycle frame structures seen so far, a plurality of poles are used for erection and welding. "It is a simple frame structure, which is suitable for users to ride. However, after years of riding," it is found that in the face of special road conditions such as climbing and accelerating roads, "it is not effective for the rider. It has an easy and effective riding effect, so we have gradually developed a transmission structure that can be appropriately shifted according to the needs of users. Problems and inconveniences in riding. According to press, the structure of the transmission on the bicycle frame currently seen is very common, please refer to the sixth figure, which is equipped with a variable speed cog on one side of the shaft structure A large gear plate 9 1, and a small gear plate 9 3 with a multi-stage variable-speed cog is installed at one end of the rear hub 9 2, and a transmission 9 4 is placed on it after a variable-speed wire is passed therethrough. The large and small gears 91 and 93 are set and passed through the transmission 94 by a key bar 9 5 and then the user can make appropriate variable-speed riding: However, the conventional transmission 9 4 groups 410206

"Changing" is to install the transmission system on the outer side of the hub 9 2. It is not only necessary to timely lubricate the multi-stage variable-speed cog small gear 9 3, because its overall is exposed-exposed and open. The interference path causes damage, and it is easy to cause rusting of the transmission mechanism due to sticking dust and sand, and it is not easy to perform the shifting motion. 'At this time, if you force the shifting motion, it is easy to produce a small gear 9 3 and a chain 9 5 each other. The teething voice's diameter shortens the overall service life. In general, the transmission 9 3 can only change the speed of a small number of segments. It cannot accurately allow the user to reach the appropriate number of segments required by the user. It is very labor-intensive and inconvenient. 'The production of conventional geared gears is not a simple method, and it can be a better structure. Therefore, the cost is also relatively high. The various problems mentioned above are the people who want to solve the present invention. (In view of this, the inventor is based on his personal long-term research and understanding of bicycle shifting knots, and in view of the key points that still need to be broken in the design of bicycles, he has invented a way to install the shifting system in the hub. The inside makes the slippery and sealing effect better, and it is not easy to be damaged by external interference. And its whole is belt-driven. It is easy to make and assemble, has a low voice, does not need additional lubrication, and can Allows larger combined tolerances, and the use of a simple mechanism can achieve the functions of stepless speed change and automatic speed change, so that users can properly adjust the input torque according to their own preferences. "The bicycle automatic internal transmission system makes it more practical Therefore, the main object of the present invention is to provide a bicycle automatic
