In particular, the second clamping portion 32 has a first end 32a and a second end 32b. The second end 32 b of the second clamping portion 32 is pivotally connected to the second end 31 b of the first clamping portion 31 by a pivot pin 36 . The second clamping portion 32 is attached to the base 14 by clamping bolts 34 . The first end 32 a of the second clamping portion 32 has a through hole through which the clamping bolt 34 passes in the installed state. The clamping bolt 34 is then threaded into a threaded hole formed in the base 14 . In this way, the first end 32 a of the second clamping portion 32 is releasably attached to the base 14 by the clamping bolt 34 . By tightening the clamping bolt 34 , the first end 32 a of the second clamping portion 32 moves toward the base 14 to fasten the first clamping portion 31 and the second clamping portion 32 around the handlebar H. As shown in FIG.

現在主要參考圖6至9，基座14包括缸孔40。在平行於第一樞軸線P1的樞軸線方向D2上觀看時，當缸孔40遠離第一樞軸線P1延伸，缸孔40定義了朝向車把安裝軸線A1傾斜的缸軸線A2。樞軸線方向D2在圖2至圖9中由符號「⨂」表示。較佳地，如圖5所示，缸軸線A2及車把安裝軸線A1形成一度至十五度範圍內的傾斜角θ。在所示實施例中，傾斜角θ為五度。Referring now primarily to FIGS. 6-9 , the base 14 includes a cylinder bore 40 . Viewed in a pivot axis direction D2 parallel to the first pivot axis P1 , the cylinder bore 40 defines a cylinder axis A2 inclined towards the handlebar mounting axis A1 as the cylinder bore 40 extends away from the first pivot axis P1 . The pivot axis direction D2 is represented by the symbol "⨂" in FIGS. 2 to 9 . Preferably, as shown in FIG. 5 , the cylinder axis A2 and the handlebar installation axis A1 form an inclination angle θ in the range of one degree to fifteen degrees. In the illustrated embodiment, the tilt angle Θ is five degrees.

液壓操作裝置10還包括活塞42。活塞42可移動地設置在缸孔40中。活塞42在缸孔40內沿缸軸線A2線性移動。操作構件16可操作地耦接至活塞42以在缸孔40內移動活塞42。操作構件16的第一樞軸線P1相對於活塞42配置，使得當操作構件16圍繞該第一樞軸線P1從該靜置位置致動到該操作位置時，操作構件16將活塞42在缸孔40內從非致動位置推動到致動位置。The hydraulic operating device 10 also includes a piston 42 . A piston 42 is movably disposed in the cylinder bore 40 . The piston 42 moves linearly within the cylinder bore 40 along the cylinder axis A2. The operating member 16 is operatively coupled to the piston 42 to move the piston 42 within the cylinder bore 40 . The first pivot axis P1 of the operating member 16 is arranged relative to the piston 42 such that when the operating member 16 is actuated about the first pivot axis P1 from the rest position to the operating position, the operating member 16 places the piston 42 in the cylinder bore 40. from the non-actuated position to the actuated position.

如圖11所示，缸孔40具有第一開口44及第二開口46。第一開口44在直徑上於第二開口46。活塞42從第一開口44***缸孔40。活塞42提供有第一環形密封環48及第二環形密封環50。第一環形密封環48提供在活塞42上，用於密封缸孔40的第一開口44。第一環形密封環48及第二環形密封環50較佳為具有均勻剖面輪廓的彈性體(例如橡膠)O形環。當活塞42在缸孔40內移動時，第一環形密封環48及第二環形密封環50可滑動地接觸缸孔40的內表面。活塞42的缸孔40及第二環形密封環50定義了液壓室，該液壓室響應於操作構件16的操作而改變尺寸。液壓室填充有諸如礦物油的液壓流體。As shown in FIG. 11 , the cylinder bore 40 has a first opening 44 and a second opening 46 . The first opening 44 is diametrically smaller than the second opening 46 . The piston 42 is inserted into the cylinder bore 40 from the first opening 44 . The piston 42 is provided with a first annular sealing ring 48 and a second annular sealing ring 50 . A first annular seal ring 48 is provided on the piston 42 for sealing the first opening 44 of the cylinder bore 40 . The first annular sealing ring 48 and the second annular sealing ring 50 are preferably elastomeric (eg, rubber) O-rings with a uniform cross-sectional profile. When the piston 42 moves within the cylinder bore 40 , the first annular seal ring 48 and the second annular seal ring 50 slidably contact the inner surface of the cylinder bore 40 . The cylinder bore 40 of the piston 42 and the second annular seal ring 50 define a hydraulic chamber that changes size in response to operation of the operating member 16 . The hydraulic chamber is filled with hydraulic fluid such as mineral oil.

液壓操作裝置10還包括在基座14及活塞42之間的活塞偏置元件54。具體而言，活塞偏置元件54設置在缸孔40中，並將活塞42偏置到非致動(靜置或非操作)位置。這裡，活塞偏置元件54是螺旋壓縮彈簧，其將活塞42偏置到非致動位置。活塞偏置元件54還將操作構件16偏置到其靜置位置(即，沒有外力施加到操作構件16)。因此，當活塞42響應於操作構件16的操作而在缸孔40中移動時，活塞42壓縮活塞偏置元件54。The hydraulically operated device 10 also includes a piston biasing element 54 between the base 14 and the piston 42 . Specifically, a piston biasing element 54 is disposed within cylinder bore 40 and biases piston 42 to a non-actuated (rest or non-operating) position. Here, the piston biasing element 54 is a helical compression spring that biases the piston 42 into the non-actuated position. The piston biasing element 54 also biases the operating member 16 to its rest position (ie, no external force is applied to the operating member 16). Thus, as the piston 42 moves within the cylinder bore 40 in response to operation of the operating member 16 , the piston 42 compresses the piston biasing element 54 .

液壓操作裝置10還包括活塞桿56。活塞桿56可操作地耦接到活塞42。液壓操作裝置10還包括連桿58。連桿58可操作地耦接在操作構件16及活塞桿56之間以將操作構件16的運動傳遞到活塞桿56。換言之，活塞桿56及連桿58將操作構件16可操作地連接到活塞42，以將操作構件16的運動傳遞到活塞42。在活塞42響應於操作構件16的操作而運動期間，藉由活塞42的運動來在缸孔40中產生液壓。特別地，活塞42在缸孔40內線性移動，以迫使液壓流體藉由軟管附接口57從缸孔40流出、藉由液壓軟管12到達受液壓操作裝置(例如，制動裝置)。The hydraulic operating device 10 also includes a piston rod 56 . Piston rod 56 is operably coupled to piston 42 . The hydraulic operating device 10 also includes a connecting rod 58 . A link 58 is operatively coupled between the operating member 16 and the piston rod 56 to transmit motion of the operating member 16 to the piston rod 56 . In other words, the piston rod 56 and connecting rod 58 operatively connect the operating member 16 to the piston 42 to transmit movement of the operating member 16 to the piston 42 . During the movement of the piston 42 in response to the operation of the operating member 16 , hydraulic pressure is generated in the cylinder bore 40 by the movement of the piston 42 . In particular, piston 42 moves linearly within cylinder bore 40 to force hydraulic fluid out of cylinder bore 40 via hose attachment port 57 , via hydraulic hose 12 to a hydraulically operated device (eg, a brake).

連桿58包括第一端58a及第二端58b。連桿58的第一端58a相對於操作構件16繞第二樞軸線P2樞轉地配置。特別地，液壓操作裝置10還包括滾子60，滾子60耦接到連桿58的第一端58a以圍繞第二樞軸線P2旋轉。操作構件16的致動部24包括接觸到該滾子60的彎曲接觸表面24b。這樣，操作構件16的操作力傳遞到連桿58，連桿58又將操作力傳遞到活塞桿56。換言之，當操作構件16繞第一樞軸線P1樞轉時，彎曲接觸表面24b藉由致動部24的接觸彎曲表面24b與滾子60接觸而推動連桿58。然後連桿58推動活塞桿56以使活塞42在缸孔40內沿缸軸線A2線性移動。這裡，連桿58包括第一連桿板62及第二連桿板64。滾子60藉由樞銷66可旋轉地支撐在第一連桿板62及第二連桿板64之間。The connecting rod 58 includes a first end 58a and a second end 58b. The first end 58a of the link 58 is pivotally arranged relative to the operating member 16 about the second pivot axis P2. In particular, the hydraulically operated device 10 also includes a roller 60 coupled to the first end 58a of the link 58 for rotation about the second pivot axis P2. The actuating portion 24 of the operating member 16 includes a curved contact surface 24 b that contacts this roller 60 . In this way, the operating force of the operating member 16 is transmitted to the link 58 , which in turn transmits the operating force to the piston rod 56 . In other words, when the operating member 16 pivots about the first pivot axis P1 , the curved contact surface 24 b pushes the link 58 by the contact curved surface 24 b of the actuating portion 24 coming into contact with the roller 60 . The connecting rod 58 then pushes the piston rod 56 to move the piston 42 linearly within the cylinder bore 40 along the cylinder axis A2. Here, the link 58 includes a first link plate 62 and a second link plate 64 . The roller 60 is rotatably supported between the first link plate 62 and the second link plate 64 by the pivot pin 66 .

連桿58的第二端58b繞第三樞軸線P3樞轉地耦接到活塞桿56。特別地，連桿58的第二端58b藉由樞銷68樞轉地耦接到活塞桿56。這裡，樞銷68的相對端由基座14支撐。換言之，基座14包括導引表面72，當操作構件16在靜置位置及操作位置之間移動時，該導引表面72導引樞銷68。具體而言，在此，樞銷68的一端提供有第一滾子68A，樞銷68的另一端提供有第二滾子68B。基座14包括第一導引槽72A及第二導引槽72B。第一滾子68A被支撐在第一導引槽72A中，第二滾子68B被支撐在第二導引槽72B中。因此，導引表面72由基座14的第一導引槽72A及第二導引槽72B形成。The second end 58b of the link 58 is pivotally coupled to the piston rod 56 about the third pivot axis P3. In particular, the second end 58b of the link 58 is pivotally coupled to the piston rod 56 by a pivot pin 68 . Here, the opposite end of the pivot pin 68 is supported by the base 14 . In other words, the base 14 includes a guide surface 72 that guides the pivot pin 68 as the operating member 16 moves between the rest position and the operative position. Specifically, here, one end of the pivot pin 68 is provided with a first roller 68A, and the other end of the pivot pin 68 is provided with a second roller 68B. The base 14 includes a first guiding groove 72A and a second guiding groove 72B. The first roller 68A is supported in the first guide groove 72A, and the second roller 68B is supported in the second guide groove 72B. Therefore, the guide surface 72 is formed by the first guide groove 72A and the second guide groove 72B of the base 14 .

在這種配置中，如圖7及圖9所見，第一樞軸線P1比第二樞軸線P2更靠近使用者接觸表面20b1。如圖7所見，第一樞軸線P1及第二樞軸線P2間隔開第一直線距離L1，其中操作構件16處於靜置位置。另一方面，如圖9所見，第一樞軸線P1及第二樞軸線P2間隔開第二直線距離L2，其中操作構件16處於操作位置。如圖7所見，第一樞軸線P1及第三樞軸線P3間隔開第三直線距離L3，其中操作構件16處於靜置位置。另一方面，如圖9所見，第一樞軸線P1及第三樞軸線P3間隔開第四直線距離L4，其中操作構件16處於操作位置。第一直線距離L1等於第二直線距離L2。第三直線距離L3不同於第四直線距離L4。In this configuration, as seen in FIGS. 7 and 9 , the first pivot axis P1 is closer to the user contact surface 20b1 than the second pivot axis P2. As seen in FIG. 7 , the first pivot axis P1 and the second pivot axis P2 are separated by a first linear distance L1 , wherein the operating member 16 is in the rest position. On the other hand, as seen in FIG. 9 , the first pivot axis P1 and the second pivot axis P2 are separated by a second linear distance L2 , wherein the operating member 16 is in the operating position. As seen in FIG. 7 , the first pivot axis P1 and the third pivot axis P3 are separated by a third linear distance L3 , wherein the operating member 16 is in the rest position. On the other hand, as seen in FIG. 9 , the first pivot axis P1 and the third pivot axis P3 are separated by a fourth linear distance L4 , wherein the operating member 16 is in the operating position. The first linear distance L1 is equal to the second linear distance L2. The third linear distance L3 is different from the fourth linear distance L4.

如圖11所見，在所示實施例中，液壓操作裝置10還包括連接到缸孔40的液壓貯器80。液壓貯器80填充有液壓流體，例如礦物油。液壓操作裝置10處於安裝狀態下，液壓貯器80設置在缸孔40上方。較佳地，液壓貯器80是沿著缸孔40延伸的細長室。即，液壓貯器80具有縱向軸線A3，該縱向軸線A3傾斜於缸孔40的缸軸線A2。液壓貯器80流體連接到缸孔40。在此，液壓貯器80內的液壓流體藉由第一流體端口82供應到缸孔40，如圖11所見。當活塞42處於靜置位置(即，操作構件16處於非操作或靜置位置)時，第一流體端口82對缸孔40的液壓室52開放。如圖11所見，液壓貯器80藉由第二流體端口84進一步流體連接到缸孔40，第二流體端口84在第一環形密封環48及第二環形密封環50之間的區域中與缸孔40連通。可選地，隔膜86可根據需要及/或期望提供在液壓貯器80中。此外，可選地，基座14可提供有洩放閥88，該洩放閥88流體連接到液壓貯器80的液壓流體室。As seen in FIG. 11 , in the illustrated embodiment, the hydraulically operated device 10 also includes a hydraulic reservoir 80 connected to the cylinder bore 40 . The hydraulic reservoir 80 is filled with hydraulic fluid, such as mineral oil. When the hydraulic operating device 10 is in an installed state, the hydraulic reservoir 80 is disposed above the cylinder hole 40 . Preferably, hydraulic reservoir 80 is an elongated chamber extending along cylinder bore 40 . That is, the hydraulic reservoir 80 has a longitudinal axis A3 that is oblique to the cylinder axis A2 of the cylinder bore 40 . Hydraulic reservoir 80 is fluidly connected to cylinder bore 40 . Here, hydraulic fluid within hydraulic reservoir 80 is supplied to cylinder bore 40 via first fluid port 82 , as seen in FIG. 11 . The first fluid port 82 is open to the hydraulic chamber 52 of the cylinder bore 40 when the piston 42 is in the rest position (ie, the operating member 16 is in the inoperative or rest position). As seen in FIG. 11 , the hydraulic reservoir 80 is further fluidly connected to the cylinder bore 40 by a second fluid port 84 that is in contact with the first annular seal ring 48 and the second annular seal ring 50 in the area between the first annular seal ring 48 and the second annular seal ring 50 . The cylinder bore 40 communicates. Optionally, a diaphragm 86 may be provided in hydraulic reservoir 80 as needed and/or desired. Furthermore, optionally, the base 14 may be provided with a relief valve 88 fluidly connected to the hydraulic fluid chamber of the hydraulic reservoir 80 .

如圖7、9及12所見，液壓操作裝置10還包括活塞位置調整器90，該活塞位置調整器90可操作地耦接至活塞42。活塞位置調整器90包括調整導引體92及調整螺栓94。調整導引體92是環形構件，其藉由樞銷96可樞轉地附接到基座14。活塞桿56穿過調整導引體92的中心開口92a並接觸活塞42。偏置元件98提供在連桿58及操作構件16的致動部24之間，使得活塞桿56偏置在活塞42上。偏置元件98的偏置力小於活塞偏置元件54的偏置力，使得偏置元件98確實使活塞42遠離調整導引體92。這裡，偏置元件98是扭力彈簧，其具有定位於樞銷22上的螺旋部分、接觸到設置在樞銷68周圍的滾子的第一腿部及接觸到使用者操作桿20的安裝部20a的第二腿部。如圖12所見，調整螺栓94螺旋入基座14中，使得調整螺栓94的尖端接觸調整導引體92。因此，藉由將調整螺栓94旋入或旋出基座14的螺紋孔，調整導引體92在樞銷96上樞轉，以改變活塞42的靜置或初始位置。As seen in FIGS. 7 , 9 and 12 , the hydraulically operated device 10 also includes a piston position adjuster 90 operatively coupled to the piston 42 . The piston position regulator 90 includes an adjustment guide 92 and an adjustment bolt 94 . The adjustment guide 92 is an annular member that is pivotally attached to the base 14 by a pivot pin 96 . The piston rod 56 passes through the central opening 92 a of the adjustment guide body 92 and contacts the piston 42 . A biasing element 98 is provided between the connecting rod 58 and the actuating portion 24 of the operating member 16 such that the piston rod 56 is biased against the piston 42 . The biasing force of the biasing element 98 is less than the biasing force of the piston biasing element 54 such that the biasing element 98 does move the piston 42 away from the adjustment guide 92 . Here, the biasing element 98 is a torsion spring having a helical portion positioned on the pivot pin 22 , a first leg that contacts a roller disposed around the pivot pin 68 and a mounting portion 20a that contacts the user lever 20 the second leg. As seen in FIG. 12 , the adjustment bolt 94 is screwed into the base 14 such that the tip of the adjustment bolt 94 contacts the adjustment guide body 92 . Thus, by screwing the adjustment bolt 94 into or out of the threaded hole of the base 14 , the adjustment guide 92 pivots on the pivot pin 96 to change the rest or initial position of the piston 42 .
