現在,將更詳細地討論導鏈器14。如圖8至14所示,導鏈器14包括內板50及外板52。內板50及外板52被建構成在其間形成導鏈槽54。這裡,內板50包括面向導鏈槽54的內表面50a。內板50還包括從內表面50a突出到導鏈槽54中的突出部件50b。突出部件50b沿內板50的下邊緣設置。Now, the
在第一實施例中,導鏈器14還包括上游連接部件56及下游連接部件58。上游連接部件56連接內板50及外板52的上游端。下游連接部件58連接內板50及外板52的下游端。如本文所用,用語「上游」及「下游」是指在對第一鏈輪S1及第二鏈輪S2施加向前踩踏動作期間,相對在導鏈槽54內的自行車鏈條CN的鏈條驅動方向CD。換言之,內板50與外板52的內表面彼此相面對而在其間形成導鏈槽54,以容納自行車鏈條CN。In the first embodiment, the
更具體地,響應於變速器的致動,藉由拉動操作纜線18的內線18b,導鏈器14相對於基座構件12於遠離自行車車架F的向外方向移動。因此,響應於操作拉纜線18的釋放操作,外板52接觸並橫向切換自行車鏈條CN,使得自行車鏈條CN相對於自行車車架F於向內方向從第一鏈輪S1移動到第二個鏈輪S2。此外,響應於變速器的致動,藉由拉動操作纜線18的內線18b,導鏈器14相對於基座構件12於遠離自行車車架F的向外方向移動。如此,導鏈器14可響應於變速器的致動而選擇性地將自行車鏈條CN定位在第一鏈輪S1及第二鏈輪S2中的一個上。More specifically, the
現在,將更詳細地討論導鏈器14。導鏈器附接元件20基本上包括第一部件60。第一部件60被建構為部分地覆蓋內板50的內表面50a,該內表面50a面向導鏈槽54,於其中有導鏈器附接元件20附接到內板50。這裡,第一部件60也至少相對於內板50為懸臂。Now, the
第一部件60建構成在導鏈器附接元件20附接到導鏈器14的內板50及前撥鏈器10安裝到自行車車架F的狀態下,在向內換檔操作期間防止鏈條從前鏈輪總成的鏈輪脫落。這裡,第一部件60建構成防止在向內換檔操作期間鏈條從前鏈輪總成FS的第二鏈輪S2脫落。換言之,第一部件60建構成防止在向內換檔操作期間鏈條從前鏈輪總成的最小鏈輪脫落。The
具體地,第一部件60包括支座(abutment) 60a,其建構成藉由使鏈條接觸支座60a來防止鏈條在向內換檔操作期間從前鏈輪總成的最小鏈輪脫落。支座60a設置在第一部件60的前端的尖端處且相對於內板50的內表面50a向內朝向導鏈器14的外板52突出。支座60a與連接部件64隔開。Specifically, the
支座60a設置在導鏈器附接元件20的最前部。與導鏈器附接元件20的任何其他部分相比,支座60a係最遠地突出到導鏈槽54中。在進行向內換檔操作時,隨著鏈條CN從第一鏈輪S1被引導到第二鏈輪S2,鏈條CN開始從第一鏈輪S1脫離,然後移動到第二鏈輪S2上。然而,如果鏈條CN在向內方向朝向自行車車架F移動至遠處,則鏈條CN接觸支座60a以防止鏈條CN脫離到第二鏈輪S2的內側。The
此外,第一部件60建構成在向外換檔操作期間與鏈條CN接觸。具體地,第一部件60包括在向外換檔操作期間接觸鏈條CN的鏈條接觸表面60b。較佳地,第一部件60的鏈條接觸表面60b位於從內板50的底部周邊邊緣向下處。這裡,第一部件60相對於內板50呈懸臂式,其中導鏈器附接元件20附接到內板50。如此,導鏈器附接元件20可響應於在向外換檔操作期間與鏈條CN的接觸而相對於導鏈器14變形。Furthermore, the
導鏈器附接元件20還包括第二部件62及連接部件64。連接部件64連接第一部件60及第二部件62。如此,第二部件62至少部分地與第一部件60間隔開。因此,第一部件60在分離區域R處至少部分地與第二部件62間隔開。較佳地,如在第一實施例中,第一部件60、第二部件62及連接部件64是整體式之一體式構件。例如,第一部件60、第二部件62及連接部件64是樹脂構件。例如,導鏈器附接元件20由硬合成樹脂(例如聚縮醛等)一體模製而成,其具有彈性及恢復性,以在向外換檔操作期間第一部件60相對第二部件62偏轉後,返回其原始狀態。這裡,鏈條接觸表面60b在連接部件64及支座60a之間延伸。此外,第二部件62具有第一端62a及第二端62b。第二端62b連接到連接部件64。The chain
參照圖8及圖9,導鏈器附接元件20還包括固定部件66。在第一實施例中,固定部件66位於連接部件64相鄰處。固定部件66被建構成附接至導鏈器14。固定部件66不含金屬材料。這裡,固定部件66包括建構成容納緊固件68的緊固件開口66a。在第一實施例中,緊固件68是將導鏈器附接元件20緊固到內板50的鉚釘。緊固件68還將下游連接部件58的凸片部58a連接到內板50。更具體地,緊固件68延伸穿過導鏈器附接元件20的緊固件開口66a,然後穿過下游連接部件58的開口58b並穿過內板50的開口50c。Referring to FIGS. 8 and 9 , the chain
較佳地,如圖12所示,第一部件60及第二部件62中的至少一個包括建構成與內板50接合的接合部。這裡,第一部件60包括接合部70。此外,這裡,第二部件62包括接合部72。在第一實施例中,接合部70包括提供到第一部件60的第一鉤70a。第一鉤70a在第一位置處鉤到內板50上。在第一實施例中,接合部72包括提供到第二部件62的第二鉤72a。第二鉤72a在與第一鉤70a的第一位置間隔開的第二位置處鉤到內板50上。Preferably, as shown in FIG. 12 , at least one of the
參考圖9,導鏈器附接元件20還包括容納空間74,其定義在第一部件60及第二部件62彼此間隔開的位置處。更具體地,容納空間74建構成至少部分地容納導鏈器14的內板50的突出部件50b。換言之,在導鏈器附接元件20安裝至前撥鏈器10的導鏈器14的狀態下,突出部件50b至少部分地位於容納空間74處。內板50的突出部件50b從內板50向導鏈槽54突出。在導鏈器附接元件20附接到導鏈器14的內板50的狀態下,第一部件60及第二部件62位於內板50的突出部件50b相鄰處。內板50的突出部件50b至少部分地定義了第一部件60及第二部件62之間的分離區域R。如圖13及14中所見,在導鏈器附接元件20附接至該導鏈器14的該內板50的狀態下,第一部件60的至少一部分比內板50的突出部件50b更遠地突出到導鏈器14的導鏈槽54中。Referring to FIG. 9 , the chain
此外,在第一實施例中,在該導鏈器附接元件20附接至該導鏈器14的該內板50的狀態下,該第二部件62的至少一部分比該內板50的該突出部件50b更遠地突出至該導鏈器14的導鏈槽54中。特別地,第二部件62從第二部件62的第一端62a到第二部件62的第二端62b逐漸變厚。較佳地,第二部件62的第二端62b比內板50的突出部件50b更突出到導鏈器14的導鏈槽54中。例如,第二部件62的第二端62b比內板50的突出部件50b更突出到導鏈器14的導鏈槽54中約0.5公釐。因此,鏈條CN通常被防止接觸到內板50的突出部件50b。然而,在向外換檔操作期間,第一部件60可相對於第二部件62向內朝向自行車車架F偏轉,使得鏈條CN接觸內板50的突出部件50b。Furthermore, in the first embodiment, in a state where the chain

在第二實施例中,導鏈器114包括內板150及外板152。內板150及外板152被建構成在其間形成導鏈槽154。在第二實施例中,導鏈器114還包括上游連接部件156及下游連接部件158。在第二實施例中,導鏈器114與前撥鏈器10的導鏈器14相同,除了內板150已被修改。這裡,內板150具有內表面150a及突出部件150b,其中突出部件150b的寬度比導鏈器14的突出部件50b寬,且內表面150a的寬度小於內表面50a的寬度。導鏈器114以與導鏈器14相同的方式來作用。In the second embodiment, the
在第二實施例中,導鏈器附接元件120基本包括第一部件160、第二部件162、連接部件164及固定部件166。導鏈器附接元件120與前撥鏈器10的導鏈器附接元件20相同,除了導鏈器附接元件120的第二部件162已被修改。這裡,第二部件162的寬度比導鏈器附接元件20的第二部件62的寬度窄。導鏈器附接元件120以與導鏈器附接元件20相同的方式來作用。In the second embodiment, the chain

導鏈器214包括內板250及外板252。內板250及外板252被建構成在其間形成導鏈槽254。這裡,內板250包括面向導鏈槽254的內表面250a。內板250還包括從內表面250a突出到導鏈槽254中的突出部件250b。內板250與上述的內板50相同,外板252與上述的外板52相同。因此,導鏈器214基本上具有與上述的導鏈器14相同的構造。The
