下文將參考圖37、圖41及圖42詳細描述自行車輪轂總成12之操作。
Hereinafter, the operation of the
如圖37中所見,軸向方向D2包括第一軸向方向D21及與第一軸向方向D21相反之第二軸向方向D22。偏置力F5在第一軸向方向D21上自偏置構件84施加至收納構件94。偏置構件84之偏置力F5使收納構件94、第一棘輪構件80、第二棘輪構件82及滑動構件90在第一軸向方向D21上朝向鏈輪支撐主體28偏置。此使第一棘輪齒80A與第二棘輪齒82A嚙合。
As seen in FIG. 37, the axial direction D2 includes a first axial direction D21 and a second axial direction D22 opposite to the first axial direction D21. The biasing force F5 is applied to the receiving
此外,如圖41中所見,當踩踏扭矩T1在傳動旋轉方向D11上輸入至鏈輪支撐主體28時,由螺旋外部花鍵齒46在第一軸向方向D21上相對於鏈輪支撐主體28導引螺旋內部花鍵齒80H1。此強有力地使第一棘輪齒80A與第二棘輪齒82A嚙合。在此狀態中,踩踏扭矩T1經由第一棘輪構件80及第二棘輪構件82(圖37)自鏈輪支撐主體28傳輸至輪轂主體36(圖37)。
In addition, as seen in FIG. 41, when the pedaling torque T1 is input to the
如圖41中所見,第一棘輪構件80接觸導引部分28G以藉由在惰轉期間在偏置構件84(圖37)與第一棘輪構件80之間產生之旋轉摩擦力F6與第二棘輪構件82脫嚙。如圖42中所見,在惰轉期間,惰轉扭矩T2在傳動旋轉方向D11上施加至輪轂主體36。惰轉扭矩T2經由第二棘輪構件82(圖37)自輪轂主體36(圖37)傳輸至第一棘輪構件80。此時,由螺旋外部花鍵齒46在第二軸向方向D22上相對於鏈輪支撐主體28導引螺旋內部花鍵齒80H1。此使第一棘輪構件80在第二軸向方向D22上抵抗偏置力F5相對於鏈輪支撐主體28移動。因此,第一棘輪構件80在第二軸向方向D22上移動
遠離第二棘輪構件82,從而致使第一棘輪齒80A與第二棘輪齒82A之間的嚙合較弱。此允許第二棘輪構件82在傳動旋轉方向D11上相對於第一棘輪構件80旋轉,從而防止惰轉扭矩T2經由第一棘輪構件80及第二棘輪構件82自輪轂主體36傳輸至鏈輪支撐主體28。此時,第一棘輪齒80A在圓周方向D1上與第二棘輪齒82A一起滑動。

第一輪輻安裝部分236A具有第一外徑DM236A。第二輪輻安裝部分236B具有第二外徑DM236B。第一外徑DM236A大於第二外徑DM236B,此係因為自由輪結構38需要相對於旋轉中心軸線A1自第一輪輻安裝部分236A徑向向內安置。然而,第一外徑DM236A可等於或小於第二外徑DM236B。

如圖47及圖48中所見,自行車輪轂總成12之鏈輪支撐主體28可包括九個外部花鍵齒40X,九個外部花鍵齒40X經構形以在外部花鍵頂徑DM11大於34mm且小於35mm時及在第一軸向長度AL1等於或大於55mm時與自行車後鏈輪總成嚙合。在此修改中,由於鏈輪支撐主體28包括九個外部花鍵齒40X且具有大於34mm且小於35mm之外部花鍵頂徑DM11,因此當前可用的具有九個內部花鍵齒之自行車後鏈輪總成可安裝於自行車輪轂總成12上。如圖47中所見,第一軸向長度AL1可等於或大於55mm。第一軸向長度AL1可等於或小於80mm。第一軸向長度AL1可等於或大於60mm。第一軸向長度AL1可等於或大於65mm。第一軸向長度AL1可為67mm。
As seen in Figures 47 and 48, the
如本文中所使用之術語「包含」及其派生詞意欲為指定所陳述特徵、元件、組件、群組、整數及/或步驟之存在但不排除其他未陳述特徵、元件、組件、群組、整數及/或步驟之存在的開放術語。此概念亦適用於類似含義之詞語,例如術語「具有」、「包括」及其派生詞。 The term "comprising" and its derivatives as used herein are intended to specify the existence of stated features, elements, components, groups, integers and/or steps but not to exclude other unstated features, elements, components, groups, Open term for the existence of integers and/or steps. This concept also applies to words with similar meanings, such as the terms "have", "include" and their derivatives.
術語「構件」、「區段」、「部分」、「部件」、「元件」、「主體」及「結構」當以單數形式使用時可具有單一部件或複數個部件之雙重含義。 The terms "component", "section", "part", "part", "component", "body" and "structure" when used in the singular form can have the dual meaning of a single part or a plurality of parts.
諸如本申請案中敍述的「第一」及「第二」之序數數目僅為標識符,而不具有任何其他含義,例如特定次序及類似者。此外,例如,術語「第一元件」自身不暗示「第二元件」之存在,且術語「第二元件」自身不暗示「第一元件」之存在。 The ordinal numbers such as "first" and "second" described in this application are only identifiers and do not have any other meaning, such as specific order and the like. In addition, for example, the term "first element" by itself does not imply the existence of "second element", and the term "second element" by itself does not imply the existence of "first element".
如本文中所使用之術語「對」可涵蓋除其中成對元件具有彼此相同的形狀或結構之構形外之其中成對元件具有彼此不同的形狀或結構之構形。 The term "pair" as used herein can encompass configurations in which the paired elements have different shapes or structures from each other except for the configuration in which the paired elements have the same shape or structure as each other.
因此,術語「一」、「一或多個」及「至少一個」在本文中可互換地使用。 Therefore, the terms "a", "one or more" and "at least one" are used interchangeably herein.
最後,如本文中所使用之諸如「實質上」、「大約」及「大致」之程度術語意謂所修飾之術語之合理量之偏差以使得最終結果並無顯著改變。本申請案中所描述之所有數值可被理解為包括諸如「實質上」、「大約」及「大致」之術語。 Finally, terms of degree such as "substantially", "approximately" and "approximately" as used herein mean a reasonable amount of deviation of the modified term so that the final result does not change significantly. All numerical values described in this application can be understood to include terms such as "substantially", "approximately" and "approximately".
顯然,鑒於以上教示,本發明之眾多修改及變化係可能的。因此應理解,在所附申請專利範圍之範疇內,可以不同於如本文中特定描述之方式的其他方式實踐本發明。 Obviously, in view of the above teachings, many modifications and variations of the present invention are possible. Therefore, it should be understood that within the scope of the appended patent application, the present invention may be practiced in other ways than those specifically described herein.
