自行車内變速器是一種將變速機構設置於車輪轂内’ 藉該變速機構所設齒輪系中的齒速比安排以及速比傳輸路徑之選擇與操縱來達到變速、省時或省力的目的，而完整的内變速器包含了行星齒輪系、動力輸入源、單向離合器、動力切斷機構以及彈簧和相關的輸入、輸出桿等等；利用動力源輸入與動力傳輸路徑的選擇而得到至少一種以上不同的速比輸出，而此種行星齒輪系的觀念早在西元188〇年即被提出，到了 1 8 9 5年融合了滑動太陽齒輪的觀念產生出具有驅動機構的自行車輪轂技術創作，而真正商品化成功的内變速器為丨896年所創作的利用一槓桿操作中空固定軸内控制桿’以控制太陽齒輪的滑動而得到不同的速比，直到目前有關的内變速器主要設計包含了三速、四速、五速、七速、十二速和將外變速器與内變速器結合而成具有内三速外七速的變速器。由於内變速系統是將傳動機構裝設於車輪轂中，因此具有如下的功能： 1内變速機構設於車輪轂中，可免於外界雜質的侵入，因此變速機構的使用壽命較長。 2無外變速器油污弄髒騎乘者或其他使用者衣褲之缺點。 3變速過程中噪音較外變速器小。 4'由於内變速器的變速原理在於運用行星齒輪、太陽齒輪等齒輪系的不同組合’配合離合器的使用’以達到不同的速比，因此内變速器變速過程沒有如外變速器變速般需考慮定位問題。The internal gearbox of a bicycle is a kind of gearbox that is installed in the wheel hub. The gearbox is equipped with gear ratios and gear ratio transmission paths. The internal transmission includes a planetary gear train, a power input source, a one-way clutch, a power cut-off mechanism, and springs and related input and output levers, etc .; at least one different type of power is obtained by selecting the power source input and the power transmission path. Speed ratio output, and the concept of this planetary gear train was proposed as early as 1880 AD. In 1895, the concept of sliding sun gear was combined to produce a bicycle hub technology creation with a driving mechanism, which was truly commercialized. The successful internal transmission was created in 896 using a lever to operate a hollow fixed shaft internal control lever 'to control the sliding of the sun gear to obtain different speed ratios. Until now, the relevant internal transmissions are mainly designed to include three-speed and four-speed , Five-speed, seven-speed, twelve-speed and a combination of an external transmission and an internal transmission Transmission. Because the transmission mechanism is installed in the wheel hub, the internal transmission system has the following functions: 1. The internal transmission mechanism is installed in the wheel hub, which can prevent the invasion of external impurities, so the service life of the transmission mechanism is longer. 2 No shortcomings of external transmission oil stains on the clothes of riders or other users. 3 During the shifting process, the noise is lower than that of the external transmission. 4'Because the shifting principle of the internal transmission is to use different combinations of planetary gears, sun gears and other gear trains 'in conjunction with the use of clutches' to achieve different speed ratios, the internal transmission does not need to consider positioning issues like the external transmission.

第4頁五、發明說明（2) 5. 内變速機構主要是由行星齒輪系所組成’而行星齒輪系為一拘束運動鏈，故換檔動作與動力的傳動較確實。 6. 變速機構和車輪轂結合成一體，所以易於裝置於自行車上。因此，世界各國相關業界基於内變速機構的實用效益與預期可見的產業經濟利益和發展，紛紛加以設計研發，諸如已知的：我國專利公告第330544號「自行車内變速機構」、公告第284734號「内裝變速機」、公告第327160號「内裝有離合器之輪轂」、公告第321624號「自行車用内裝有變速裝置之輪轂」等等。美國專利第484 22 91號、第4854191號、第Re.33058號、第4947703 號、第4973297 號、第5011464 號、第5069655 歆、第5078664 號、第5083991 號、第5236403 號、第52735 00 號、第 52735 0 1 號、第 53 1 8486 號、第 5322487 號、第537 8 2 0 1 號、第5 39 9 1 2 8 號、第 54432 79 號、第 5445 5 73 號、第5 469755 號、第 55 27 230 號、第554 045 6 號、第 555 6354 號、第5590894 號、第5769750 號、第5785625 號、第5829563號、第58 33040號等等。然而，内變速器與外變速器相比較又發現，内變速器的重量、體積以及速比的選擇範圍較窄，因此不適用於競赛用車和登山車，絕大部份適用於城市通勤用自行車、電動變速自行車以及摺疊式自行車等等對象；而相關内部設計結構的複雜，元件多、重量重、體積大，速比選擇範圍5. Explanation of the invention (2) 5. The internal transmission mechanism is mainly composed of a planetary gear train 'and the planetary gear train is a restraint motion chain, so the shifting action and power transmission are more reliable. 6. The transmission mechanism and the wheel hub are integrated into one body, so it can be easily installed on a bicycle. Therefore, the relevant industries in various countries around the world have designed and researched and developed based on the practical benefits of the internal gear shift mechanism and the expected industrial economic benefits and developments. For example, it is known: China Patent Bulletin No. 330544 "Bicycle Internal Gear Shifting Mechanism" and Bulletin No. 284734 "Built-in gearbox", Bulletin No. 327160, "Hub with built-in clutch", Bulletin No. 321624, "Bucket with built-in gearbox," etc. U.S. Patent Nos. 484 22 91, 4854191, Re.33058, 4947703, 4973297, 5011464, 5069655, 5078664, 5083991, 5236403, 52735 00 , 52735 01, 53 1 8486, 5322487, 537 8 2 01, 5 39 9 1 2 8, 54432 79, 5445 5 73, 5 469755, 55 27 230, 554 045 6, 555 6354, 5590894, 5769750, 5785625, 5829563, 58 33040 and so on. However, comparing the internal transmission with the external transmission, it was found that the selection range of the weight, volume and speed ratio of the internal transmission is narrow, so it is not suitable for racing cars and mountain bikes. Most of them are suitable for urban commuting bicycles, Electric variable speed bicycles, folding bicycles, etc .; and the related internal design structure is complex, with many components, heavy weight, large volume, and speed ratio selection range
