當自行車煞車裝置1之驅動組件30的無線通訊器311收到來自中央控制系統的致動訊號時,控制電路板309依據此致動訊號令驅動器301開始運作。驅動器301透過這些傳動齒輪306傳動於輸出軸302,而使輸出軸302與固定於輸出軸302的二凸輪303一同轉動。在二凸輪303轉動的過程中,二凸輪303推抵第一桿體131的環形凸緣1313,而帶動第一桿體131,以使連接於第一桿體131的活塞12移動而產生致動前煞車卡鉗的油壓,並使第一桿體131的受推部1311分離於第二桿體132的推抵部1321。When the
如此一來,手動操作二個煞車手把組件之其中一者的煞車拉桿,不僅可致動與***作之煞車把手組件連接的煞車卡鉗之外,還可驅使另一煞車把手組件以電動的方式致動另一煞車卡鉗,來進行輔助煞車。In this way, manually operating the brake lever of one of the two brake handle assemblies can not only actuate the brake caliper connected to the operated brake handle assembly, but also drive the other brake handle assembly in an electric manner. Activate the other brake caliper to provide auxiliary braking.
在本實施例中,藉由驅動組件30之驅動器301連接於輸出軸302,二凸輪303固定於輸出軸302並抵靠於第一桿體131的環形凸緣1313,以及輸出軸302的中心軸線A1垂直並相交於第一桿體131的中心軸線A2的配置,可使第一桿體131被驅動組件30平順地驅動,而帶動活塞12於液壓腔室111內移動,故可確保活塞12能如預期地增加煞車油的壓力。In this embodiment, the
此外,在二凸輪303推抵第一桿體131的過程中,二凸輪303推抵第一桿體131的合力(如箭頭F所示)為沿著第一桿體131的中心軸線A2施予第一桿體131,藉此可使得第一桿體131被驅動的順暢度更為提升。In addition, in the process of the two
應注意的是,凸輪303的數量並不以二個為限。在其他實施例中,驅動組件可僅包含一凸輪。在這樣的配置下,輸出軸可不用穿過第一桿體,而使得第一桿體可不用有穿槽的結構,且第一桿體的凸緣可不用為環形。It should be noted that the number of
另一方面,藉由連桿13的第二桿體132之推抵部1321可分離地抵靠於第一桿體131的受推部1311,以及驅動組件30可帶動第一桿體131,而使第一桿體131的受推部1311分離於第二桿體132之推抵部1321的配置,可使第一桿體131在被驅動的過程中不用帶動其他元件(如第二桿體132、搖擺件21及拉柄22),故可減少所需之驅動器301的輸出力。On the other hand, the pushing
此外,第二桿體132之導引部1322是用來在第一桿體131相對第二桿體132移動時導引第一桿體131的受推部1311。但,應注意的是,第二桿體132之導引部1322為選用的結構而可在其他實施例中進行省略。In addition, the
再者,連桿13的第二桿體132之推抵部1321並不限於可分離地抵靠於第一桿體131的受推部1311。若所採用之驅動器的輸出力足夠,則連桿的第二桿體與第一桿體可為一體地相連而不可分離的配置,而使得第一桿體不需要有受推部及第二桿體不需要有推抵部。Furthermore, the pushing
上述之中央控制系統是依據左煞車把手組件之缸體內的活塞的移動才發送致動驅動器301的致動訊號予無線通訊器311,但並不以此為限。在其他實施例中,中央控制系統可依據輪速感測器所感測之後輪的輪速變化過大發送致動驅動器的致動訊號予無線通訊器。The above-mentioned central control system sends the activation signal of the
在本實施例中,控制電路板309與中央控制系統之間是無線通訊,但並不以此為限。在其他實施例中,控制電路板與中央控制系統之間可為有線通訊。舉例來說,中央控制系統可透過電纜電性連接於控制電路板的電連接器。如此,驅動組件可省略無線通訊器,而訊號可透過電纜以有線的方式於中央控制系統與控制電路板之間傳輸,且供給中央控制系統的電力亦可透過電纜提供給控制電路板及與控制電路板電性連接的元件。In this embodiment, the communication between the
應注意的是,編碼器310為選配的元件。在其他實施例中,驅動組件可無編碼器。此外,驅動組件30並不限包含有傳動齒輪306。在其他實施例中,驅動組件可無傳動齒輪,而驅動器可直接驅動輸出軸。再者,軸承307及墊圈308亦為選配的元件。在其他實施例中,驅動組件可無軸承及墊圈。It should be noted that the
根據上述實施例所揭露的自行車煞車裝置,藉由驅動組件之驅動器連接於輸出軸,二凸輪固定於輸出軸並抵靠於第一桿體的環形凸緣,以及輸出軸的中心軸線垂直並相交於第一桿體的中心軸線的配置,可使第一桿體被驅動組件平順地驅動,而帶動活塞於液壓腔室內移動,故可確保活塞能如預期地增加煞車油的壓力。According to the bicycle braking device disclosed in the above embodiment, the driver of the driving assembly is connected to the output shaft, the two cams are fixed on the output shaft and abut against the annular flange of the first rod body, and the central axes of the output shaft are perpendicular to and intersect with each other. The arrangement on the central axis of the first rod allows the first rod to be smoothly driven by the driving component and drives the piston to move in the hydraulic chamber, thus ensuring that the piston can increase the pressure of the brake oil as expected.
再者,在二凸輪推抵第一桿體的過程中,二凸輪推抵第一桿體的合力為沿著第一桿體的中心軸線施予第一桿體,藉此可使得第一桿體被驅動的順暢度更為提升。Furthermore, in the process of the two cams pushing against the first rod, the resultant force of the two cams pushing against the first rod is applied to the first rod along the central axis of the first rod, thereby making the first rod The smoothness of the body being driven is further improved.
此外,藉由連桿的第二桿體之推抵部可分離地抵靠於第一桿體的受推部,以及驅動組件可帶動第一桿體,而使第一桿體的受推部分離於第二桿體之推抵部的配置,可使第一桿體在被驅動的過程中不用帶動其他元件(如第二桿體、搖擺件及拉柄),故可減少所需之驅動器的輸出力。In addition, the pushing portion of the second rod body of the connecting rod can detachably abut against the pushed portion of the first rod body, and the driving assembly can drive the first rod body, so that the pushed portion of the first rod body The configuration of the pushing part that is separated from the second rod body allows the first rod body to be driven without driving other components (such as the second rod body, the rocking member and the pull handle), so the required driver can be reduced. output force.
