The flywheel is mainly composed of a plurality of large and small toothed discs with different outer diameters and matching different numbers of teeth, and a ratchet wheel. The ratchet wheel allows the large and small toothed discs to rotate in one direction only and cannot be reversed. Sorted in descending order. The rider can control the front and rear transmissions through two shifting handles fixed on the left and right sides of the handlebar to change the gear ratio between the front gearwheel and the flywheel gearwheel, thereby adjusting the pedaling light weight or the vehicle speed. However, each toothed disc of the conventional lock-type or cassette flywheel is fixed adjacent to each other through a sleeve shaft of the ratchet. The inner diameter of the sleeve hole in the middle of the smallest toothed disk is subject to the outside of the sleeve shaft. The diameter limit cannot be reduced, so the smallest gear of the flywheel cannot be made smaller due to the above limitations. Generally, the smallest gear is probably 14 teeth. At present, the smallest gear has 11 teeth. However, even if the smallest gear is only 11 teeth, Cannot meet the needs of small wheel bike riders. Although 7-tooth teeth have appeared recently, the non-locking type is adopted. The flywheel structure adopts a one-way bearing structure, which is different from and incompatible with the flywheel structure using the ratchet structure of the present invention. In view of this, the inventor has improved it, and the invention has been produced.

It is intended to remove the connection between the flywheel 1 and the tooth surface 210 of the one end 21 of the hub 20. As shown in Figures 7 and 8, first unscrew the nut 221 and remove the sleeve 220. Hold a hollow removal tool 30 with a ratchet surface 31 on the outer surface of one end and extend into the center hole 142 of the end gear 14. Inside and protruding to the end, the end of the removal tool 30 will touch the end of one end 21 of the hub 20, the ratchet surface 31 of the removal tool 30 just meshes with the inner wall 115 of the ratchet 11 of the ratchet 11, so it is removed by rotation The tool 30 can drive the ratchet wheel 11 to move in unison, so that the internal screw 114 of the ratchet wheel 11 is separated from the tooth surface 210 of the one end 21 of the hub 20, so that the flywheel 1 can be disassembled and separated from the hub 20.

其次，上述末端齒輪14與該中介穿套件10配置小齒盤組13端間之結合方式，除了上述以第二螺牙段140與第二螺孔105以鎖牙式結合手段結合外，亦可於該中介穿套件10配置小齒盤組13端設置一結合孔1050(即該第二螺孔105以該結合孔1050取代)，該末端齒輪14之結合端1400亦可改為相配合之構造，可嵌入該結合孔1050內，該結合端1400與結合孔1050間以卡接式之結合手段1A結合及固定，且該末端齒輪14與該中介穿套件10卡接後可一起連動及不脫離，亦可達到相同的結合效果。 Secondly, in addition to the combination of the above-mentioned end gear 14 and the end of the small-toothed disk set 13 of the interposer penetrating kit 10, in addition to the above-mentioned combination of the second screw segment 140 and the second screw hole 105 by means of a locking tooth combination, A coupling hole 1050 is provided at the 13 end of the small gear set 13 provided in the interposer 10 (that is, the second screw hole 105 is replaced by the coupling hole 1050). The coupling end 1400 of the end gear 14 can also be changed to a matching structure. Can be embedded in the coupling hole 1050, the coupling end 1400 and the coupling hole 1050 are combined and fixed by a snap-type coupling means 1A, and the end gear 14 can be linked and not disengaged after being snapped with the interposer 10 , Can also achieve the same combination effect.

據上，本發明之末端齒輪14因未穿套在該中介穿套件的第二穿套軸101上，因此該末端齒輪14的中心孔142不受該第二穿套軸101的外直徑限制，因此該末端齒輪14的外直徑可變小，相對齒數可更少。如各圖式所示，本發明之末端齒輪14齒數可為8齒，較習知之最末齒盤為11齒或14齒齒數更少，可增加車子的齒輪比。 According to the above, since the end gear 14 of the present invention is not sleeved on the second sleeve shaft 101 of the interposer, the center hole 142 of the end gear 14 is not limited by the outer diameter of the second sleeve shaft 101. Therefore, the outer diameter of the final gear 14 can be made smaller, and the relative number of teeth can be smaller. As shown in the drawings, the number of teeth of the final gear 14 of the present invention can be eight teeth, which is less than the conventionally known final tooth plate of 11 teeth or 14 teeth, which can increase the gear ratio of the car.

綜上所述，本發明確可達到預期之功能及目的，並且詳細說明能 使熟於此技藝者得據以實施，然以上所舉之實施例僅用以說明本發明，舉凡所有等效結構之改變仍不脫離本發明之權利範疇。 In summary, the present invention can indeed achieve the intended function and purpose, and the detailed description can Those skilled in the art can implement it accordingly, but the above-mentioned embodiments are only used to illustrate the present invention, and all changes to the equivalent structure still do not depart from the scope of rights of the present invention.
