Description
本發明係與自行車的剎車把手有關，特別是指一種油壓剎車把手裝置。The present invention relates to a brake handle of a bicycle, and more particularly to a hydraulic brake handle device.
一般自行車的剎車器，以剎車作動方式可分為鋼索拉動及油壓推動，由於以油壓推動方式具有不會斷線、無鬆弛且動作確實等特點，能提升剎車的安全性，因而被廣泛的使用。Generally, the brakes of bicycles can be divided into cable pulling and hydraulic pushing by means of brake actuation. Since the hydraulic pushing method has the characteristics of no disconnection, no slack, and correct action, the safety of the brake can be improved, and thus it is widely used. usage of.
又一般習知的油壓剎車器主要係藉由設於自行車手把上的油壓剎車把手來驅動，而該油壓剎車把手內部僅設計有單一活塞缸的油室，因此，按壓剎車把手(Brake Lever)後，會造成該油壓剎車器執行剎車動作速度不足，而無法立即執行剎車動作。The conventional hydraulic brake is mainly driven by a hydraulic brake handle provided on the bicycle handlebar, and the hydraulic brake handle is only designed with an oil chamber of a single piston cylinder, so the brake handle is pressed ( Brake Lever) will cause the hydraulic brake to perform insufficient braking and cannot perform the braking action immediately.
另一方面，正因為按壓剎車把手後，會造成該油壓剎車器執行剎車動作速度不足，因此，該油壓剎車器在組裝上都會縮短其剎車片與碟盤之間的距離，而此組裝方式容易使泥沙卡固於剎車片與碟盤之間，不但造成剎車片或碟盤的磨損，並因此而產生噪音，同時造成不易清除泥沙之不便。On the other hand, just because pressing the brake handle will cause the hydraulic brake to perform insufficient braking speed, the hydraulic brake will shorten the distance between the brake pad and the disc in assembly, and the assembly is assembled. The method is easy to make the sand stuck between the brake pad and the disc, which not only causes the brake pad or the disc to wear, but also causes noise, and at the same time causes inconvenience of not easily removing the sand.

以上所述即為本發明實施例各主要構件之結構及其組態說明。至於本發明的作動方式及功效請參考以下的說明。The above description is the structure and configuration description of each main component of the embodiment of the present invention. Please refer to the following description for the mode of operation and efficacy of the present invention.
參閱第3、4圖所示，顯示該按把30處於未按壓作動的狀態，即該活塞40的第二塞部43位於第一位置。參閱第6、7圖所示，顯示該按把30處於按壓作動中的狀態，即該活塞40的第二塞部43位於第二位置。在該第二塞部43由第一位置朝該第二位置移動之過程中，該第二油室24內的油會經由該第一油道251而流入該第一油室22內，並由該油出口23流出，同時，該第一油室22內的油同樣會經由該油出口23流出，直到該第一塞部42封設該第一油道251，即第二塞部43位於第二位置時，該第二油室24內的油才停止流入該第一油室22內，藉以控制該油壓剎車器12作動。是以，在該第二塞部43由第一位置朝該第二位置移動過程中，該油壓剎車器12同時受該第一、二塞部42、43分別在該第一、二油室22、24活動時推抵輸出的油量所控制，而得以增加該油壓剎車器12作動的速度，讓該油壓剎車器12加快執行剎車動作。反觀習知油壓剎車器，若其所控制的油壓剎車器12的剎車片與碟盤之間的距離與本發明所控制的油壓剎車器12的剎車片121與碟盤13之間的距離相同時，習知油壓剎車器的作動僅單靠單一油室所輸出的油所控制，其油壓剎車器的作動速度勢必較慢於 本發明，而無法加快執行剎車動作。Referring to Figures 3 and 4, the push button 30 is shown in an unactuated state, i.e., the second plug portion 43 of the piston 40 is in the first position. Referring to Figures 6 and 7, the push button 30 is shown in a state of being pressed, i.e., the second plug portion 43 of the piston 40 is in the second position. During the movement of the second plug portion 43 from the first position toward the second position, the oil in the second oil chamber 24 flows into the first oil chamber 22 via the first oil passage 251, and The oil outlet 23 flows out, and the oil in the first oil chamber 22 also flows out through the oil outlet 23 until the first plug portion 42 encloses the first oil passage 251, that is, the second plug portion 43 is located at the second plug portion 43. In the second position, the oil in the second oil chamber 24 stops flowing into the first oil chamber 22, thereby controlling the hydraulic brake 12 to operate. Therefore, during the movement of the second plug portion 43 from the first position to the second position, the hydraulic brake 12 is simultaneously received by the first and second plug portions 42 and 43 in the first and second oil chambers, respectively. 22, 24 is controlled by the amount of oil pushed to the output, and the speed at which the hydraulic brake 12 is actuated is increased, and the hydraulic brake 12 is accelerated to perform the braking action. Referring to the conventional hydraulic brake, if the distance between the brake pad and the disk of the hydraulic brake 12 controlled by the present invention is between the brake pad 121 and the disk 13 of the hydraulic brake 12 controlled by the present invention. When the distance is the same, the operation of the conventional hydraulic brake is only controlled by the oil output from a single oil chamber, and the hydraulic brakes must be slower than the hydraulic brake. According to the present invention, it is not possible to speed up the execution of the braking action.
另一方面，由於本發明得以增加油壓剎車器12的作動速度，因此，使得油壓剎車器12在組裝上可增加剎車片121與碟盤13之間距離的配置，避免泥沙卡固於剎車片121與碟盤13之間，以達到減少剎車片121或碟盤13的磨損、降低噪音，以及便於清除泥沙等目的。On the other hand, since the present invention can increase the operating speed of the hydraulic brake 12, the hydraulic brake 12 can be assembled to increase the distance between the brake pad 121 and the disc 13 to prevent the sand from being stuck. The brake pad 121 is disposed between the brake pad 121 and the disc 13 to reduce the wear of the brake pad 121 or the disc 13, to reduce noise, and to facilitate the removal of sediment.
參閱第8、9圖所示，顯示該按把30處於按壓作動後的狀態，即該活塞40的第二塞部43位於第三位置，由於該第二塞部43保持封設該第一油道251，且該第二塞部43係位於該前、後分流道252、253之間。因此，在該第二塞部43由第二位置朝該第三位置移動過程中，該第二塞部43所推抵的油會流經該前分流道252、儲油室27、後分流道253而回流至該第二塞部43後方的第二油室24內，以解決第二油室24內油流向的問題。Referring to Figures 8 and 9, the button 30 is shown in a state after the pressing operation, that is, the second plug portion 43 of the piston 40 is in the third position, since the second plug portion 43 keeps the first oil sealed. Lane 251, and the second plug portion 43 is located between the front and rear split runners 252, 253. Therefore, during the movement of the second plug portion 43 from the second position toward the third position, the oil pushed by the second plug portion 43 flows through the front shunt passage 252, the oil storage chamber 27, and the rear shunt passage. 253 is returned to the second oil chamber 24 behind the second plug portion 43 to solve the problem of oil flow in the second oil chamber 24.
最後，放開所按壓的按把30，此時，藉由該第一、二彈簧50、60的彈性恢復力，而推移該第一、二塞部42、43至初始位置。同時，該活塞40也推抵該按把30使其恢復至原始位置，以等待下次按壓執行剎車動作。Finally, the pressed handle 30 is released, and at this time, the first and second plug portions 42, 43 are pushed to the initial position by the elastic restoring force of the first and second springs 50, 60. At the same time, the piston 40 also pushes the handle 30 back to its original position to wait for the next press to perform the braking action.
參閱第11圖所示，本發明中亦可單獨使用該第一彈簧50，也就是該第一彈簧50是沿該第一塞部42活動方向地設於該第一油室22與該第一塞部42之間，於該第一塞部42及第二塞部43朝該油出口23方向活動時提供一 彈性恢復力。或者如第12圖所示，單獨使用該第二彈簧60，也就是該第二彈簧60是沿該第二塞部43活動方向地設於該第二油室24與該第二塞部43之間，於該第一塞部42及第二塞部43朝該油出口23方向活動時提供一彈性恢復力。Referring to FIG. 11, the first spring 50 can also be used alone in the present invention, that is, the first spring 50 is disposed in the first oil chamber 22 and the first along the movable direction of the first plug portion 42. Providing a gap between the plug portions 42 when the first plug portion 42 and the second plug portion 43 move toward the oil outlet 23 Resilience. Or, as shown in FIG. 12, the second spring 60 is used alone, that is, the second spring 60 is disposed in the second oil chamber 24 and the second plug portion 43 along the movable direction of the second plug portion 43. During the movement of the first plug portion 42 and the second plug portion 43 toward the oil outlet 23, an elastic restoring force is provided.
綜上所述，此實施例及圖示僅為本發明的較佳實施例而已，當不能以之限定本發明實施之範圍，即大凡依本發明申請專利範圍所作的均等變化與修飾，皆應屬本發明專利涵蓋的範圍內。In the above, the embodiments and the illustrations are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equal changes and modifications made by the scope of the patent application of the present invention should be It is within the scope of the patent of the present invention.
