但在傳統煞車裝置中，前輪煞車致動機構係離開連動煞車桿設置，且因此一操作力有時會在該操作力從連動煞車桿到前輪煞車致動機構的傳輸路徑中遭受到一傳輸損失。However, in the conventional brake device, the front wheel brake actuating mechanism is disposed away from the interlocking brake lever, and thus an operating force sometimes suffers a transmission loss in the transmission path of the operating force from the linked brake lever to the front wheel brake actuation mechanism. .

舉例來說，在專利文獻1所揭示之煞車裝置中，前輪煞車致動機構係設置在與連動煞車桿所在車把相對的車把上(此二車把為左和右車把)，使得連動煞車桿之操作力經由一纜索傳輸到前輪煞車致動機構。因此，會因為一內索與一外索之間的摩擦的發生一傳輸損失。For example, in the brake device disclosed in Patent Document 1, the front wheel brake actuation mechanism is disposed on the handlebar opposite to the handlebar on which the brake lever is located (the two handlebars are left and right handlebars), so that linkage The operating force of the brake lever is transmitted to the front wheel brake actuating mechanism via a cable. Therefore, there is a transmission loss due to the friction between the inner cable and the outer cable.

本發明已鑑於上述問題製作，且因此其一目的是提出一種在一操作力從一連動煞車桿到一前輪煞車致動機構之傳 輸路徑中具備一減小傳輸損失的煞車裝置，及一種跨坐型車輛。The present invention has been made in view of the above problems, and it is therefore an object to provide a transmission of an operating force from a linkage brake lever to a front wheel brake actuation mechanism.

依據本發明，有可能實現一種在一操作力從一連動煞車桿到一前輪煞車致動機構之傳輸路徑中具備一減小傳輸損失的煞車裝置。該跨坐型車輛舉例來說可為一摩托車(包含速可達型機車)、四輪推車(buggy)或類似物。According to the present invention, it is possible to realize a brake device having a reduced transmission loss in a transmission path from a linkage brake lever to a front wheel brake actuation mechanism. The straddle type vehicle may be, for example, a motorcycle (including a speed-up locomotive), a four-wheeled truck (buggy) or the like.

在本發明之一態樣中，一用於延遲該操作力從該連動煞車桿到該前輪煞車致動機構之傳輸的游隙可被提供在該連動煞車桿與該前輪煞車致動機構之間。依據此態樣，當該連動煞車桿***作時，有可能比作動該前輪煞車更快作動該後輪煞車。In one aspect of the invention, a play for delaying transmission of the operating force from the linkage brake lever to the front wheel brake actuation mechanism may be provided between the linkage brake lever and the front wheel brake actuation mechanism . According to this aspect, when the linked brake lever is operated, it is possible to actuate the rear brake faster than the front brake.

According to this aspect, it is possible to suppress the transmission of the operating force of one of the linked brake levers to the side of the front wheel brake lever.

在本發明之更另一態樣中，該煞車裝置可更進一步包含：一後輪煞車纜索，其用於將該連動煞車桿之一操作力傳輸至該後輪煞車；及一輸入構件，其接收該連動煞車桿之操作力以拉引該後輪煞車纜索且將該操作力輸入該前煞車致動機構，且該輸入構件可為附接於該連動煞車桿。In still another aspect of the present invention, the brake device may further include: a rear wheel brake cable for transmitting an operating force of the one of the linked brake levers to the rear wheel brake; and an input member Receiving the operating force of the interlocking brake lever to pull the rear wheel brake cable and input the operating force to the front brake actuation mechanism, and the input member may be attached to the linkage brake lever.

在此態樣中，該輸入構件可提供為可被當該連動煞車桿操作時從該前輪煞車致動機構接收之一反作用力移位，且該後輪煞車纜索可抵抗該輸入構件所接收之該反作用力抑制該輸入構件之位移，使得該輸入構件在該輸入構件之位移抑制的狀態下抵抗該反作用力將該連動煞車桿之操作力輸入該前輪煞車致動機構。依據此組態，有可能在該後輪煞車纜索受損時阻止該連動煞車桿之一操作力從該輸入構件輸入該前輪煞車桿致動機構。In this aspect, the input member can be provided to receive a reaction force displacement from the front wheel brake actuation mechanism when the linkage brake lever is operated, and the rear wheel brake cable is resistant to receipt by the input member The reaction force suppresses displacement of the input member such that the input member inputs the operating force of the linked brake lever to the front wheel brake actuating mechanism against the reaction force in a state where the displacement of the input member is suppressed. According to this configuration, it is possible to prevent an operation force of one of the linked brake levers from inputting the front wheel brake lever actuating mechanism from the input member when the rear wheel brake cable is damaged.

在此態樣中，該輸入構件可有一欲由該後輪煞車纜索支撐的支承部分及一用於將該連動煞車桿之操作力輸入該前輪煞車致動機構的操作力輸入部分，且可附接於該連動煞車桿以便可旋轉地移位。該支承部分可構成藉由被該後輪煞車纜索支撐而抑制該輸入構件之旋轉位移，且一從該輸 入構件之旋轉位移之一中心到該操作力輸入部分的距離小於從該中心到該支承部分的距離。藉由此組態，有可能經由該輸入構件加大一從該連動煞車桿到該前輪煞車致動機構的操作力輸入。In this aspect, the input member may have a support portion to be supported by the rear wheel brake cable and an operation force input portion for inputting the operation force of the linked brake lever into the front wheel brake actuation mechanism, and may be attached Connected to the interlocking lever for rotatably shifting. The support portion may constitute a rotation displacement of the input member by being supported by the rear wheel brake cable, and one from the The distance from one of the rotational displacements of the member to the operating force input portion is less than the distance from the center to the support portion. With this configuration, it is possible to increase an operating force input from the interlocking lever to the front wheel brake actuating mechanism via the input member.

在此態樣中，該輸入構件可為一均衡器，且該均衡器可有一欲由該連動煞車桿支撐為可旋轉的旋轉支承部分、一提供在一離開該旋轉支承部分之位置用以拉引該後輪煞車纜索的纜索附接部分、及一提供在一離開該旋轉支承部分之位置用以將該連動煞車桿之操作力輸入該前輪煞車致動機構的操作力輸入部分。依據此組態，有可能利用該均衡器將該連動煞車桿之一操作力劃分為一欲經由該前輪煞車致動機構輸入該前輪煞車的力及一欲經由該後輪煞車纜索輸入該後輪煞車的力，且抑制區分比例變化。在此例中，該輸入構件之旋轉支承部分可為提供於該操作力輸入部分與該纜索附接部分之間。In this aspect, the input member can be an equalizer, and the equalizer can have a rotary support portion to be supported by the linkage brake lever, and a position to be pulled away from the rotary support portion.

According to this configuration, it is possible to use the equalizer to divide the operating force of one of the linked brake levers into a force to be input to the front wheel brake via the front wheel brake actuating mechanism and to input the rear wheel via the rear wheel brake cable The force of the brakes is suppressed, and the proportional change is suppressed. In this case, the rotary support portion of the input member may be provided between the operating force input portion and the cable attachment portion.

在本發明之更另一態樣中，該煞車裝置可更進一步包含：一輸入構件，其用於將該連動煞車桿之一操作力輸入該前輪煞車致動機構；及一施力構件，其用於將一力依一相反於該輸入構件輸入該連動煞車桿之操作力之方向的方向施加於該前輪煞車致動機構。依據此態樣，有可能延遲該連動煞車桿之一操作力從該前輪煞車致動機構到該前輪煞車之傳輸，且比作動該前輪煞車更早作動該後輪煞車。In still another aspect of the present invention, the brake device may further include: an input member for inputting an operating force of one of the linked brake levers into the front wheel brake actuation mechanism; and a force applying member A direction is applied to the front wheel brake actuating mechanism in a direction opposite to a direction in which the input member inputs the operating force of the interlocking lever. According to this aspect, it is possible to delay the transmission of the operating force of one of the linked brake levers from the front wheel brake actuating mechanism to the front wheel brake, and to actuate the rear wheel brake earlier than the front wheel brake.

在本發明之更另一態樣中，該操作力傳輸構件是一從該等車把之一者朝另一者延伸的桿。由於桿相較於纜索不會 隨著時間經過而變長，用一桿當作一操作力傳輸構件即無需由一使用者及一長度調整機構進行長度調整作業。因此，有可能阻止使用者進行不正確的調整。舉例來說，有可能阻止使用者將該操作力傳輸構件調整成一使一液壓永遠是由該前輪煞車致動機構在液體路徑內產生的長度。In still another aspect of the invention, the operating force transmitting member is a rod extending from one of the handlebars toward the other. Because the rod will not be compared to the cable As time passes, it becomes longer, and one rod is used as an operation force transmitting member, that is, it is not necessary to perform length adjustment work by a user and a length adjusting mechanism. Therefore, it is possible to prevent the user from making an incorrect adjustment. For example, it is possible to prevent the user from adjusting the operating force transmitting member to a length such that a hydraulic pressure is always generated in the liquid path by the front wheel brake actuating mechanism.

在此態樣中，該桿可耦接於該前輪煞車致動機構及一提供於該前輪煞車桿之聯結部分，且該桿可具備一調整機構用以調整該前輪煞車致動機構與該聯結部分間之一距離。依據此組態，有可能設定該聯結部分與該前輪煞車致動機構間之適當距離。整體而言，該前輪煞車桿被支撐在一離開該等車把的位置。有可能藉由調整該前輪煞車桿之聯結部分與該前輪煞車致動機構間之距離而適當地設定該等車把與該前輪煞車桿間之距離。In this aspect, the lever can be coupled to the front wheel brake actuation mechanism and a coupling portion provided to the front wheel brake lever, and the lever can be provided with an adjustment mechanism for adjusting the front wheel brake actuation mechanism and the coupling One of the distances between the rooms. According to this configuration, it is possible to set an appropriate distance between the coupling portion and the front wheel brake actuating mechanism.

首先詳細說明連動煞車桿40。如圖7所示，連動煞車桿40具有一依水平方向延伸欲在一煞車作業進行時讓騎士抓握的抓握部分40e。一對上和下板狀基部40c、40d被提供在車輛寬度方向中之中心側上抓握部分40e之末端。基部40c、40d具有相應旋轉支承部分40a、40a，該等旋轉支承部分在彼此對應的位置具備相應孔40g、40g。如圖8所示，主缸32具備孔32b、32b，且孔32b、32b之位置對應於孔40g、40g之位置。一軸頸構件(在此為螺栓)43穿過孔32b、32b和孔40g、40g(參見圖4或圖6)。依此方式，連動煞車桿40可繞軸頸構件43旋轉。如圖6所示，一螺帽44經由一墊圈45裝配在軸頸構件43之遠端。First, the interlocking lever 40 will be described in detail. As shown in Fig. 7, the interlocking brake lever 40 has a grip portion 40e which is extended in the horizontal direction to allow the knight to grip while a bicycle operation is being performed. A pair of upper and lower plate-like bases 40c, 40d are provided at the ends of the grip portion 40e on the center side in the vehicle width direction. The base portions 40c, 40d have respective rotation support portions 40a, 40a having respective holes 40g, 40g at positions corresponding to each other. As shown in Fig. 8, the master cylinder 32 is provided with holes 32b, 32b, and the positions of the holes 32b, 32b correspond to the positions of the holes 40g, 40g. A journal member (here a bolt) 43 passes through the holes 32b, 32b and the holes 40g, 40g (see Fig. 4 or Fig. 6). In this manner, the interlocking brake lever 40 is rotatable about the journal member 43. As shown in FIG. 6, a nut 44 is fitted to the distal end of the journal member 43 via a washer 45.

如圖7所示，基部40c、40d具有用於將旋轉構件42支撐為可旋轉的相應旋轉支承部分40b、40b。旋轉支承部分40b、40b被定位在相應旋轉支承部分40a、40a之前方(依離開車把4之方向看)。特定言之，旋轉支承部分40b、40b亦在彼此面對的位置具備相應孔40h、40h。旋轉構件42亦在一對應於孔40h、40h的位置具備一孔42g(參見圖9)。如圖4所示，旋轉構件42設置在上和下基部對40c、40d之間，且一軸頸構件(在此為螺栓)46穿過旋轉構件42之孔42g及孔40h、40h。依此方式，旋轉支承部分40b、40b將旋轉 構件42支撐為可旋轉。如圖6所示，一墊圈47裝配在軸頸構件46之遠端。一固持構件(在此為一開尾銷)48穿過軸頸構件46之遠端藉以將軸頸構件46固定於連動煞車桿40。As shown in FIG. 7, the base portions 40c, 40d have respective rotation support portions 40b, 40b for supporting the rotation member 42 to be rotatable. The rotary support portions 40b, 40b are positioned in front of the respective rotary support portions 40a, 40a (as seen in the direction away from the handlebar 4). Specifically, the rotary support portions 40b, 40b are also provided with corresponding holes 40h, 40h at positions facing each other. The rotating member 42 is also provided with a hole 42g at a position corresponding to the holes 40h, 40h (see Fig. 9). As shown in FIG. 4, the rotating member 42 is disposed between the upper and lower base pairs 40c, 40d, and a journal member (here, a bolt) 46 passes through the hole 42g of the rotating member 42 and the holes 40h, 40h. In this way, the rotary support portions 40b, 40b will rotate Member 42 is supported for rotation. As shown in FIG. 6, a washer 47 is fitted to the distal end of the journal member 46. A retaining member (here an open tail pin) 48 passes through the distal end of the journal member 46 to secure the journal member 46 to the associated brake lever 40.

如圖6或圖7所示，基部40d具備一往下突出的止動件40f。另一方面，如圖5至圖8所示，主缸32具備一往前突出的旋轉限制部分32c，且旋轉限制部分32c被定位在一對應於非操作狀態中(連動煞車桿40未***作轉動的狀態)連動煞車桿40之止動件40f的位置。旋轉限制部分32c藉由在連動煞車桿40未***作的狀態中接觸止動件40f而限制連動煞車桿40之旋轉。As shown in FIG. 6 or FIG. 7, the base portion 40d is provided with a stopper 40f that protrudes downward. On the other hand, as shown in FIGS. 5 to 8, the master cylinder 32 is provided with a rotation restricting portion 32c that protrudes forward, and the rotation restricting portion 32c is positioned in a non-operating state (the interlocking lever 40 is not operated). The state of rotation) interlocks the position of the stopper 40f of the brake lever 40. The rotation restricting portion 32c restricts the rotation of the interlocking lever 40 by contacting the stopper 40f in a state in which the interlocking lever 40 is not operated.

以下說明旋轉構件42。如圖5或圖9所示，旋轉構件42係設置為從旋轉支承部分40b朝車輛寬度方向之中心(依圖5之方向C)延伸，且有一旋轉支承部分42a、一纜索附接部分42b及一臂施壓部分42c。The rotating member 42 will be described below. As shown in FIG. 5 or FIG. 9, the rotating member 42 is disposed to extend from the rotation supporting portion 40b toward the center in the vehicle width direction (direction C in FIG. 5), and has a rotation supporting portion 42a, a cable attachment portion 42b, and One arm presses the portion 42c.

旋轉支承部分42a被定位在旋轉構件42之一端，且具備前述之孔42g。The rotation support portion 42a is positioned at one end of the rotation member 42, and is provided with the aforementioned hole 42g.

纜索附接部分42b被提供在一離開旋轉支承部分42a朝向車輛寬度方向之中心的位置。後輪煞車纜索11之一端附接於纜索附接部分42b。在本實例中，如圖6所示，一圓柱形接合部分11d被提供在內索11a之對應末端。另一方面，一用於容納圓柱形接合部分11d的凹穴形成於纜索附接部分42b中，允許接合部分11d和纜索附接部分42b彼此接合。如圖9所示，一缺口42e形成於纜索附接部分42b中。內索11a通過缺口42e朝車輛寬度方向之中心延伸。The cable attachment portion 42b is provided at a position away from the center of the rotation support portion 42a toward the vehicle width direction. One end of the rear wheel brake cable 11 is attached to the cable attachment portion 42b. In the present example, as shown in Fig. 6, a cylindrical engaging portion 11d is provided at the corresponding end of the inner cable 11a. On the other hand, a recess for accommodating the cylindrical engaging portion 11d is formed in the cable attachment portion 42b, allowing the engaging portion 11d and the cable attaching portion 42b to be engaged with each other. As shown in Fig. 9, a notch 42e is formed in the cable attachment portion 42b. The inner cable 11a extends toward the center in the vehicle width direction through the notch 42e.

臂施壓部分42c形成在一面對臂31(詳見下文)之一桿側受壓部分31c的位置。在本實例中，如圖5所示，臂施壓部分42c係形成為從旋轉支承部分42a朝握把4b延伸。The arm pressing portion 42c is formed at a position facing one of the lever-side pressed portions 31c of the arm 31 (see below). In the present example, as shown in Fig. 5, the arm pressing portion 42c is formed to extend from the rotation supporting portion 42a toward the grip 4b.

如前所述，旋轉構件42被提供為可繞軸頸構件46旋轉。後輪煞車纜索11抵抗當連動煞車桿40***作時旋轉構件42從臂31接收之一反作用力調節旋轉構件42之旋轉(回縮)。旋轉構件42在旋轉構件42之旋轉被調節的狀態下抵抗該反作用力將連動煞車桿40之一操作力輸入至臂31。也就是說，纜索附接部分42b被內索11a拉往車輛寬度方向之中心，調節旋轉構件42之旋轉。當連動煞車桿40***作時，旋轉構件42被內索11a支撐在臂31側上，且臂施壓部分42c抵抗從臂31接收之反作用力將連動煞車桿40之一操作力輸入至臂31。As previously mentioned, the rotating member 42 is provided to be rotatable about the journal member 46. The rear wheel brake cable 11 resists the rotation (retraction) of the rotation member 42 receiving a reaction force from the arm 31 when the interlocking brake lever 40 is operated. The rotating member 42 inputs an operating force of the interlocking brake lever 40 to the arm 31 against the reaction force in a state where the rotation of the rotating member 42 is adjusted. That is, the cable attachment portion 42b is pulled by the inner cable 11a toward the center in the vehicle width direction to adjust the rotation of the rotary member 42. When the interlocking lever 40 is operated, the rotating member 42 is supported by the inner cable 11a on the arm 31 side, and the arm pressing portion 42c resists the reaction force received from the arm 31 to input an operating force of the interlocking lever 40 to the arm 31. .

如圖10所示，從形成於旋轉支承部分42a中之孔42g之中心P到臂施壓部分42c的距離L1短於從中心P到纜索附接部分42b的距離L2。藉由此組態，從旋轉構件42輸入至臂31的力可被加大。As shown in Fig. 10, the distance L1 from the center P of the hole 42g formed in the rotary support portion 42a to the arm pressing portion 42c is shorter than the distance L2 from the center P to the cable attachment portion 42b. With this configuration, the force input from the rotating member 42 to the arm 31 can be increased.

接下來說明前輪煞車致動機構30。如圖2和圖3所示，前輪煞車致動機構30設置在左車把4上(在車把4當中具備連動煞車桿40的車把上)連動煞車桿40附近。也就是說，前輪煞車致動機構30係提供在依車輛寬度方向看之連動煞車桿40內側上(依圖3所示方向A)。如前所述，前輪煞車致動機構30包含臂31和主缸32。圖11是臂31之一透視圖。Next, the front wheel brake actuating mechanism 30 will be described. As shown in FIGS. 2 and 3, the front wheel brake actuating mechanism 30 is disposed on the left handlebar 4 (on the handlebar of the handlebar 4 having the interlocking brake lever 40) in the vicinity of the brake lever 40. That is, the front wheel brake actuating mechanism 30 is provided on the inner side of the interlocking brake lever 40 as viewed in the vehicle width direction (in the direction A shown in FIG. 3). As previously mentioned, the front wheel brake actuation mechanism 30 includes an arm 31 and a master cylinder 32. Figure 11 is a perspective view of one of the arms 31.

如圖4或圖8所示，主缸32具有一受壓部分32a、一附接 部分32f及一對上和下桿支撐部分32d、32d。As shown in FIG. 4 or FIG. 8, the master cylinder 32 has a pressure receiving portion 32a and an attachment. The portion 32f and the pair of upper and lower rod support portions 32d, 32d.

附接部分32f具有半圓形狀。附接部分32f和一同樣具有半圓形狀的附接構件33在其間固持著握把4b內側之車把4部分。依此方式，主缸32附接於車把4(參見圖5或圖6)。The attachment portion 32f has a semicircular shape. The attachment portion 32f and an attachment member 33 also having a semicircular shape hold the handlebar 4 portion inside the grip 4b therebetween. In this manner, the master cylinder 32 is attached to the handlebar 4 (see Fig. 5 or Fig. 6).

當騎士進行一煞車作業時，受壓部分32a被臂31之一缸施壓部分31a(詳見下文)施壓從而向一裝在主缸32內的活塞(圖中未示)施壓。然後，受壓部分32a提高液壓路徑12內之煞車油的液壓以作動前輪煞車14。在本實例中，受壓部分32a之端面依車輛寬度方向(依相反於圖3所示方向A之方向)面朝橫向，使得受壓部分32a之端面面向臂31之缸施壓部分31a(參見圖5)。受壓部分32a被一裝在主缸32內的彈簧(圖中未示)依車輛寬度方向往橫向推動。When the knight performs a braking operation, the pressed portion 32a is pressed by a cylinder pressing portion 31a (see below) of the arm 31 to apply pressure to a piston (not shown) housed in the master cylinder 32. Then, the pressed portion 32a raises the hydraulic pressure of the brake oil in the hydraulic path 12 to actuate the front wheel brake 14. In the present example, the end surface of the pressed portion 32a faces the lateral direction in the vehicle width direction (in the direction opposite to the direction A shown in Fig. 3) such that the end surface of the pressed portion 32a faces the cylinder pressing portion 31a of the arm 31 (see Figure 5). The pressed portion 32a is urged laterally in the vehicle width direction by a spring (not shown) housed in the master cylinder 32.

In the present example, one of the arms 31 is provided with a rotary support portion 31d (see below) between the rotary bearing portions 40a, 40a of the interlocking brake lever 40 (see Fig. 11), and the rotary support portions are disposed on the upper and lower levers. The support portion is between 32d and 32d. The rod supporting portions 32d, 32d are provided with the aforementioned respective holes 32b, 32b (see Fig. 8). The journal member 43 passes through the holes 32b, 32b, interlocking the holes 40g, 40g of the brake lever 40 and the hole 31b of the arm 31 (see below). In this manner, the interlocking lever 40 and the arm 31 are supported to be rotatable by the lever supporting portions 32d, 32d. A washer 44 and a nut 45 are fitted to one end of the journal member 43 (see Fig. 6).

如圖8所示，主缸32除了前述受壓部分32a和其他部分更具有一貯槽32e、一傳輸纜索支撐部分32g(參見圖6)、一後 輪煞車纜索支撐部分32h、及一液壓路徑聯結部分32i。As shown in Fig. 8, the master cylinder 32 has a sump 32e, a transmission cable supporting portion 32g (see Fig. 6), and a rear portion in addition to the aforementioned pressure receiving portion 32a and other portions. The rim cable support portion 32h and a hydraulic path coupling portion 32i.

The sump 32e supplies brake oil to the hydraulic path 12, for example, when the brake pad 16a is worn. A transmission cable supporting portion 32g is formed at a lower portion of the master cylinder 32 for holding one end of one of the outer cables 21b of the transmission cable 21 (see Fig. 6). The rear wheel brake cable supporting portion 32h holds one end of the cable 11b of the rear wheel brake cable 11. The hydraulic path 12 is connected to the hydraulic path coupling portion 32i (see Fig. 6).

如圖6所示，一經由一導線(圖中未示)連接到摩托車1之一停車燈的停車燈開關35附接於主缸32之下表面。停車燈開關35在連動煞車桿40未***作時為斷路且停車燈開關35被連動煞車桿40之止動件40f壓下，當騎士進行一煞車操作時停車燈開關35被接通且其與止動件40f分開。As shown in FIG. 6, a parking light switch 35 connected to one of the parking lights of the motorcycle 1 via a wire (not shown) is attached to the lower surface of the master cylinder 32. The stop light switch 35 is open when the interlocking brake lever 40 is not operated, and the stop light switch 35 is pressed by the stopper 40f of the brake lever 40. When the rider performs a brake operation, the stop light switch 35 is turned on and its The stoppers 40f are separated.

接下來說明臂31。如圖11所示，臂31具備缸施壓部分31a、旋轉支承部分31d、桿側受壓部分31c、及一受拉部分31e。Next, the arm 31 will be described. As shown in Fig. 11, the arm 31 includes a cylinder pressing portion 31a, a rotation supporting portion 31d, a rod side pressure receiving portion 31c, and a tension portion 31e.

孔31b形成於旋轉支承部分31d之中心，且軸頸構件43如前所述穿過孔31b。當一操作力從連動煞車桿40或前輪煞車桿20輸入時，臂31繞軸頸構件43旋轉使缸施壓部分31a向主缸32之受壓部分32a施壓。The hole 31b is formed at the center of the rotation support portion 31d, and the journal member 43 passes through the hole 31b as described above. When an operating force is input from the interlocking brake lever 40 or the front wheel brake lever 20, the arm 31 is rotated about the journal member 43 to press the cylinder pressing portion 31a toward the pressed portion 32a of the master cylinder 32.

臂31具有一從旋轉支承部分31d橫向延伸的***部分31f。***部分31f之一側面向旋轉構件42之臂施壓部分42c，且當作桿側受壓部分31c(參見圖5)。The arm 31 has a raised portion 31f extending laterally from the rotary support portion 31d. One side of the swelled portion 31f presses the portion 42c toward the arm of the rotating member 42, and functions as a rod side pressed portion 31c (see Fig. 5).

一用於延遲一操作力從連動煞車桿40到煞車致動機構30 之傳輸的游隙被提供在連動煞車桿40與臂31之間。在此實例中，如圖5所示，當連動煞車桿40處於非操作狀態時，提供一間隙h當作桿側受壓部分31c與旋轉構件42之臂施壓部分42c之間的游隙。One for delaying an operating force from the interlocking brake lever 40 to the brake actuation mechanism 30 The transmitted play is provided between the linked brake lever 40 and the arm 31.

The pulling portion 21c is configured to pull the tension portion 31e to transmit the movement of the front wheel brake lever 20 to the front wheel brake actuation mechanism 30 when the front wheel brake lever 20 is operated, and to move away from the tension portion 31e when the linkage brake lever 40 is operated. The movement of the linked brake lever 40 is not transmitted to the front wheel brake lever 20 for a distance.

特定言之，如圖4所示，拉動部分21c具有一基部21d及一對從基部21d垂直延伸的板21e、21e。板21e、21e具備相應孔21f、21f，該等孔在連動煞車桿40***作時受拉部分31e之移動方向中呈長形(參見圖4及圖6)。另一方面，如 圖11所示，一孔31h形成於受拉部分31e之中心。受拉部分31e設置在板對21e、21e之間，且一銷22穿過孔31h和孔21f、21f。受拉部分31e藉由銷22與拉動部分21c保持接合。依此方式，臂31可在一操作力從連動煞車桿40輸入到臂31時(連動煞車桿40***作時)相對於傳輸纜索21移位。也就是說，受拉部分31e與銷22一起在板21e、21e間之空間內相對於內索21a移動。依此方式，即使是在連動煞車桿40***作的情況中，連動煞車桿40之移動不會傳輸到前輪煞車桿20。Specifically, as shown in Fig. 4, the pulling portion 21c has a base portion 21d and a pair of plates 21e, 21e extending perpendicularly from the base portion 21d. The plates 21e, 21e are provided with corresponding holes 21f, 21f which are elongated in the moving direction of the tension portion 31e when the interlocking lever 40 is operated (see Figs. 4 and 6). On the other hand, like As shown in Fig. 11, a hole 31h is formed at the center of the tension portion 31e. The tensioned portion 31e is disposed between the pair of plates 21e, 21e, and a pin 22 passes through the hole 31h and the holes 21f, 21f. The tensioned portion 31e is held in engagement with the pulling portion 21c by the pin 22. In this manner, the arm 31 can be displaced relative to the transmission cable 21 when an operating force is input from the interlocking brake lever 40 to the arm 31 (when the linkage lever 40 is operated). That is, the tension portion 31e moves together with the pin 22 in the space between the plates 21e, 21e with respect to the inner cable 21a. In this manner, even in the case where the interlocking brake lever 40 is operated, the movement of the interlocking brake lever 40 is not transmitted to the front wheel brake lever 20.

如圖6所示，一墊圈25裝配在銷22之遠端。一固持構件(在此為一開尾銷)26在墊圈25之外側穿過銷22之遠端。固持構件26阻止銷22從拉動部分21c滑脫。一螺旋彈簧28設置在拉動部分21c之基部21d與傳輸纜索支撐部分32g之間。螺旋彈簧28依使基部21d與傳輸纜索支撐部分32g間之距離加大的方向施加一力。螺旋彈簧28經設置為環繞內索21a。一外徑等於螺旋彈簧28內徑的管27附接於內索21a。管27使螺旋彈簧28相對於內索21a的位置安定以防螺旋彈簧28晃蕩發出聲響。As shown in FIG. 6, a washer 25 is fitted to the distal end of the pin 22. A retaining member (here an open tail pin) 26 passes through the distal end of the pin 22 on the outside of the washer 25. The holding member 26 prevents the pin 22 from slipping off the pulling portion 21c. A coil spring 28 is disposed between the base portion 21d of the pulling portion 21c and the transmission cable supporting portion 32g. The coil spring 28 applies a force in a direction in which the distance between the base portion 21d and the transmission cable supporting portion 32g is increased. The coil spring 28 is disposed to surround the inner cable 21a. A tube 27 having an outer diameter equal to the inner diameter of the coil spring 28 is attached to the inner cable 21a. The tube 27 stabilizes the position of the coil spring 28 with respect to the inner cable 21a to prevent the coil spring 28 from swaying to make an audible sound.

如圖11所示，受拉部分31e和***部分31g藉由一依鉛直方向延伸的柱31i耦接。臂31持續受推致使缸施壓部分31a與主缸32之受壓部分32a保持接觸。在本實例中，如圖6所示，一扭轉彈簧34提供橫跨柱31i和軸頸構件43延伸藉以將柱31i朝主缸32拉引。As shown in Fig. 11, the tensioned portion 31e and the raised portion 31g are coupled by a post 31i extending in the vertical direction. The arm 31 is continuously urged to keep the cylinder pressing portion 31a in contact with the pressed portion 32a of the master cylinder 32. In the present example, as shown in FIG. 6, a torsion spring 34 provides extension across the post 31i and the journal member 43 to pull the post 31i toward the master cylinder 32.

以下說明煞車裝置10之操作。圖12和圖13是用來解釋當 連動煞車桿40***作時之煞車裝置10操作的圖。圖14是一示出當時臂31之受拉部分31e如何在傳輸纜索21之板21e、21e之間移動。圖15是一用來解釋當前輪煞車桿20***作時之煞車裝置10操作的圖。首先說明當連動煞車桿40***作時之煞車裝置10操作。The operation of the brake device 10 will be described below. Figures 12 and 13 are used to explain when A diagram of the operation of the brake device 10 when the brake lever 40 is operated. Figure 14 is a view showing how the tension portion 31e of the arm 31 is moved between the plates 21e, 21e of the transmission cable 21. Figure 15 is a diagram for explaining the operation of the brake device 10 when the current rim lever 20 is operated. First, the operation of the brake device 10 when the interlocking brake lever 40 is operated will be described.

如前所述，在如圖5所示之起始狀態中(煞車作業未進行的狀態)，旋轉構件42之臂施壓部分42c以間隙h分隔於臂31之桿側受壓部分31c。As described above, in the initial state shown in FIG. 5 (the state in which the brake operation is not performed), the arm pressing portion 42c of the rotating member 42 is partitioned by the rod side pressure receiving portion 31c of the arm 31 with the gap h.

當騎士如圖12所示開始操作連動煞車桿40時，連動煞車桿40開始繞軸頸構件43朝握把4b旋轉。因此，後輪煞車纜索11之內索11a被旋轉構件42拉引以開始作動後輪煞車17。此時僅只旋轉構件42之臂施壓部分42c和臂31之桿側受壓部分31c彼此接觸；因此，臂31尚未被轉動，且前輪煞車14尚未開始被作動。When the knight starts operating the interlocking lever 40 as shown in Fig. 12, the interlocking lever 40 starts to rotate about the journal member 43 toward the grip 4b. Therefore, the inner cable 11a of the rear wheel brake cable 11 is pulled by the rotating member 42 to start the rear wheel brake 17 . At this time, only the arm pressing portion 42c of the rotating member 42 and the rod side pressed portion 31c of the arm 31 are in contact with each other; therefore, the arm 31 has not been rotated, and the front wheel brake 14 has not started to be actuated.

在此之後，當騎士如圖13所示更進一步操作連動煞車桿40且連動煞車桿40繞軸頸構件43朝握把4b旋轉時，旋轉構件42之臂施壓部分42c向臂31之桿側受壓部分31c施壓。因此，臂31亦繞軸頸構件43旋轉，且缸施壓部分31a向主缸32之受壓部分32a施壓。依此方式，前輪煞車14開始被作動。After that, when the knight further operates the interlocking lever 40 as shown in FIG. 13 and the interlocking lever 40 is rotated about the journal member 43 toward the grip 4b, the arm pressing portion 42c of the rotating member 42 is toward the rod side of the arm 31. The pressed portion 31c is pressed. Therefore, the arm 31 also rotates around the journal member 43, and the cylinder pressing portion 31a presses the pressed portion 32a of the master cylinder 32. In this way, the front wheel brake 14 begins to be actuated.

此時銷22如圖14所示沿著形成於傳輸纜索21板21e、21e的孔21f、21f移動，允許臂31之受拉部分31e在傳動纜索21之板21e、21e之間移動而不改變拉動部分21c之位置。這防止當連動煞車桿40***作時連動煞車桿40之一操作被傳 輸到前輪煞車桿20。At this time, the pin 22 is moved along the holes 21f, 21f formed in the transmission cable 21 plates 21e, 21e as shown in Fig. 14, allowing the tension portion 31e of the arm 31 to move between the plates 21e, 21e of the transmission cable 21 without changing. Pull the position of the portion 21c. This prevents the operation of one of the linked brake levers 40 from being transmitted when the linked brake lever 40 is operated. Lost to the front wheel brake lever 20.

如前所述，從旋轉構件42之旋轉位移中心P到臂施壓部分42c的距離L1短於從中心P到纜索附接部分42b的距離L2(參見圖10)。藉由此組態，一由臂施壓部分42c施加於桿側受壓部分31c的壓緊力會加大，允許抵抗一從桿側受壓部分31c接收之反作用力轉動臂31而不大幅轉動(縮回)旋轉構件42。As described above, the distance L1 from the rotational displacement center P of the rotating member 42 to the arm pressing portion 42c is shorter than the distance L2 from the center P to the cable attachment portion 42b (see Fig. 10). With this configuration, the pressing force applied to the rod-side pressed portion 31c by the arm pressing portion 42c is increased, allowing the arm 31 to be rotated against the reaction force received from the rod-side pressure receiving portion 31c without being greatly rotated. (Retracting) the rotating member 42.

接下來說明當前輪煞車桿20***作時之煞車裝置10的操作。Next, the operation of the brake device 10 when the current rim lever 20 is operated will be described.

當騎士操作前輪煞車桿20時，前輪煞車桿20拉引傳輸纜索21，且拉動部分21c拉引臂31之受拉部分31e。因此，如圖15所示，臂31繞軸頸構件43旋轉，且缸施壓部分31a向主缸32之受壓部分32a施壓。依此方式，前輪煞車14被作動。此時旋轉構件42之臂施壓部分42c和臂31之桿側受壓部分31c彼此分隔比起始狀態時更遠。When the knight operates the front wheel brake lever 20, the front wheel brake lever 20 pulls the transmission cable 21, and the pulling portion 21c pulls the tension portion 31e of the arm 31. Therefore, as shown in Fig. 15, the arm 31 rotates around the journal member 43, and the cylinder pressing portion 31a presses the pressed portion 32a of the master cylinder 32. In this way, the front wheel brake 14 is actuated. At this time, the arm pressing portion 42c of the rotating member 42 and the rod side pressed portion 31c of the arm 31 are spaced apart from each other farther than the initial state.

最後說明當後輪煞車纜索11之內索11a被切斷或從旋轉構件42鬆脫時的煞車裝置10操作。圖16是一用來解釋當內索11a從旋轉構件42鬆脫時的煞車裝置10操作。Finally, the operation of the brake device 10 when the inner cable 11a of the rear wheel brake cable 11 is cut or released from the rotating member 42 will be described. Figure 16 is a view for explaining the operation of the brake device 10 when the inner cable 11a is released from the rotating member 42.

當騎士在內索11a從旋轉構件42鬆脫的狀態下操作連動煞車桿40時，連動煞車桿40如圖16所示繞軸頸構件43朝握把4b旋轉。此時旋轉構件42之臂施壓部分42c與臂31之桿側受壓部分31c接觸。然旋轉構件42繞軸頸構件46旋轉(縮回)，且因此旋轉構件42之臂施壓部分42c無法抵抗裝在主缸32內之彈簧之膨脹力向桿側受壓部分31c施壓。這防止 當連動煞車桿40係在內索11a從旋轉構件42鬆脫之狀態下***作時僅有前輪煞車14作動。When the kiosk operates the interlocking lever 40 in a state where the inner cable 11a is released from the rotating member 42, the interlocking lever 40 rotates around the journal member 43 toward the grip 4b as shown in FIG. At this time, the arm pressing portion 42c of the rotating member 42 is in contact with the rod side pressed portion 31c of the arm 31. However, the rotating member 42 is rotated (retracted) around the journal member 46, and thus the arm pressing portion 42c of the rotating member 42 cannot press the rod side pressed portion 31c against the expansion force of the spring housed in the master cylinder 32. This prevents When the interlocking brake lever 40 is operated while the inner cable 11a is released from the rotating member 42, only the front wheel brake 14 is actuated.

在上述煞車裝置10中，前輪煞車致動機構30係設置在連動煞車桿40附近。因此，相較於連動煞車桿和前輪煞車致動機構係設置為彼此分開且連動煞車桿之操作係經由一金屬線或類似物傳輸到前輪煞車致動機構的情況，有可能減小一操作力在一操作力從連動煞車桿40到前輪煞車致動機構30之傳輸路徑中的傳輸損失。In the above-described brake device 10, the front wheel brake actuating mechanism 30 is disposed in the vicinity of the interlocking brake lever 40. Therefore, it is possible to reduce an operating force as compared with the case where the interlocking brake lever and the front wheel brake actuating mechanism are disposed apart from each other and the operation of interlocking the brake lever is transmitted to the front wheel brake actuating mechanism via a wire or the like. The transmission loss in the transmission path from the interlocking brake lever 40 to the front wheel brake actuation mechanism 30 at an operating force.

本發明並不侷限於上述煞車裝置10，且可對其進行多樣修改。舉例來說，在以上說明中，後輪煞車纜索11經由旋轉構件42連接於連動煞車桿40。但後輪煞車纜索亦可為直接連接於連動煞車桿。圖17是一當作依據此實施例之煞車裝置之一實例的煞車裝置10A之平面圖。在圖17中，與前述相似的部分將被賦予相似參考數字且不再次說明。The present invention is not limited to the above-described brake device 10, and various modifications can be made thereto. For example, in the above description, the rear wheel brake cable 11 is coupled to the interlocking brake lever 40 via the rotating member 42. However, the rear wheel brake cable can also be directly connected to the linked brake lever. Figure 17 is a plan view showing a brake device 10A as an example of a brake device according to this embodiment. In FIG. 17, portions similar to those described above will be given similar reference numerals and will not be described again.

煞車裝置10A包含一連動煞車桿40A和一旋轉構件42A。連動煞車桿40A包含一纜索附接部分40k，後輪煞車纜索11之接合部分11d被該纜索附接部分固持。一來自螺旋彈簧11c的拉力作用於後輪煞車纜索11之內索11a(參見圖1)。連動煞車桿40A具有一旋轉支撐部分40L。旋轉支撐部分40L被定位在纜索附接部分40k與臂31之桿側受壓部分31c，且將旋轉構件42A支撐為可旋轉。其中旋轉構件42A具有一旋轉支承部分42h，且軸頸構件(例如螺栓)46穿過旋轉支承部分42h及連動煞車桿40A之旋轉支撐部分40L。旋轉構件42A亦有一纜索側支承部分42i。纜索側支承部分42i與受 拉力作用之內索11a接觸。這將旋轉構件42A之旋轉(回縮)限制在背對於臂31所在側之方向中。The brake device 10A includes a linkage brake lever 40A and a rotating member 42A. The interlocking brake lever 40A includes a cable attachment portion 40k, and the engaging portion 11d of the rear wheel brake cable 11 is held by the cable attachment portion. A pulling force from the coil spring 11c acts on the inner cable 11a of the rear wheel brake cable 11 (see Fig. 1). The interlocking brake lever 40A has a rotation support portion 40L. The rotation support portion 40L is positioned at the cable attachment portion 40k and the rod side pressure receiving portion 31c of the arm 31, and supports the rotation member 42A to be rotatable. The rotating member 42A has a rotation supporting portion 42h, and a journal member (for example, a bolt) 46 passes through the rotating support portion 42h and the rotating support portion 40L of the interlocking lever 40A. The rotating member 42A also has a cable side supporting portion 42i. Cable side support portion 42i and receiving The inner cable 11a is in contact with the pulling force. This restricts the rotation (retraction) of the rotating member 42A in the direction away from the side where the arm 31 is located.

接下來說明煞車裝置10A之操作。當連動煞車構件40A被一騎士進行之煞車動作使其朝該騎士(朝握把4b)旋轉時，旋轉構件42A之臂施壓部分42c向臂31之桿側受壓部分31c施壓，且從桿側受壓部分31c接收一反作用力。後輪煞車纜索11之內索11a與纜索側支承部分42i接觸，且將旋轉構件42A支撐在桿側受壓部分31c側面上抵抗旋轉構件42A從臂31接收之反作用力。由於旋轉構件42A被內索11a支撐，旋轉構件42A向桿側受壓部分31c施壓而不以反方向(圖17中之方向E)轉動，且將連動煞車桿40A之操作力輸入到臂31。Next, the operation of the brake device 10A will be described. When the interlocking brake member 40A is rotated by the knight to the knight (toward the grip 4b), the arm pressing portion 42c of the rotating member 42A presses the rod-side pressed portion 31c of the arm 31, and The rod side pressure receiving portion 31c receives a reaction force. The inner cable 11a of the rear wheel brake cable 11 is in contact with the cable side support portion 42i, and the rotary member 42A is supported on the side of the rod side pressure receiving portion 31c against the reaction force received by the rotary member 42A from the arm 31. Since the rotating member 42A is supported by the inner cable 11a, the rotating member 42A presses the rod side pressed portion 31c without rotating in the reverse direction (direction E in Fig. 17), and inputs the operating force of the interlocking brake lever 40A to the arm 31. .

接下來說明煞車裝置10A在內索11a未連接之狀態下的操作。在內索11a未連接之狀態下，旋轉構件42A被允許依背對於臂31所在側之方向旋轉。因此，如同參照圖16所述之例，當連動煞車桿40A朝騎士旋轉時，旋轉構件42A之臂施壓部分42c從臂31之桿側受壓部分31c接收一反作用力，且旋轉構件42A無法抵抗該反作用力而依背對於桿側受壓部分31c之方向(圖17之方向E)轉動。依此方式，有可能在內索11a未連接時連動煞車桿40A***作的情況中防止僅有前輪煞車14作動。煞車裝置10A之操作已如上所述。Next, the operation of the brake device 10A in a state where the inner cable 11a is not connected will be described. In a state where the inner cable 11a is not connected, the rotating member 42A is allowed to rotate in the direction opposite to the side where the arm 31 is located. Therefore, as in the example described with reference to Fig. 16, when the interlocking lever 40A is rotated toward the knight, the arm pressing portion 42c of the rotating member 42A receives a reaction force from the rod side pressed portion 31c of the arm 31, and the rotating member 42A cannot The reaction is reversed in the direction of the rod-side pressed portion 31c (direction E in Fig. 17). In this manner, it is possible to prevent only the front wheel brake 14 from being actuated in the case where the interlocking brake lever 40A is operated when the inner cable 11a is not connected. The operation of the brake device 10A has been as described above.

在前述煞車裝置10中，一間隙h提供在臂31之桿側受壓部分31c與旋轉構件42之臂施壓部分42c之間(參見圖5)。此間隙在連動煞車桿40***作時延遲前輪煞車14之作動相對 於後輪煞車17之作動的開始。但延遲前輪煞車14之作動的機構並不侷限於此。舉例來說，可事先依相反於臂31之移動方向的方向對臂31施加一力藉以延遲前輪煞車14之作動。In the aforementioned braking device 10, a gap h is provided between the rod-side pressed portion 31c of the arm 31 and the arm pressing portion 42c of the rotating member 42 (see Fig. 5). This gap delays the actuation of the front wheel brake 14 when the linked brake lever 40 is operated. At the beginning of the operation of the rear wheel brakes 17. However, the mechanism for delaying the operation of the front wheel brake 14 is not limited thereto. For example, a force may be applied to the arm 31 in a direction opposite to the direction of movement of the arm 31 to delay the actuation of the front wheel brake 14.

在前述煞車裝置10中，旋轉構件42係當作一將連動煞車桿40之一操作力輸入到臂31的構件。然亦可使用一均衡器當作一將連動煞車桿40之一操作力輸入到臂31的構件。In the aforementioned braking device 10, the rotating member 42 is regarded as a member that inputs an operating force of the interlocking lever 40 to the arm 31. However, an equalizer can also be used as a member for inputting an operating force of the linked brake lever 40 to the arm 31.

圖18是一當作依據此實施例之煞車裝置之一實例的煞車裝置10B之平面圖。圖19是一煞車裝置10B之一均衡器64和一臂61的分解透視圖。圖20是一均衡器64和臂61的平面圖。圖21是一均衡器64之放大圖。圖22是一從前方觀看之煞車裝置10B之一主缸32B的透視圖。在這些圖式中，與前述煞車裝置10之部分相似的部分將被賦予相似參考數字且不再次說明。在煞車裝置10B中，臂61和主缸32B構成一前輪煞車致動機構30B。Figure 18 is a plan view showing a brake device 10B as an example of a brake device according to this embodiment. Figure 19 is an exploded perspective view of an equalizer 64 and an arm 61 of a brake device 10B. Figure 20 is a plan view of an equalizer 64 and an arm 61. 21 is an enlarged view of an equalizer 64. Figure 22 is a perspective view of a master cylinder 32B of a brake device 10B as viewed from the front. In these drawings, portions similar to those of the aforementioned brake device 10 will be given similar reference numerals and will not be described again. In the brake device 10B, the arm 61 and the master cylinder 32B constitute a front wheel brake actuating mechanism 30B.

如圖18所示，除了均衡器64和臂61，煞車裝置10B更包含一連動煞車桿40B及一施力構件65，該施力構件用於事先依相反於臂61在煞車作業進行時移動之方向的方向施加一力。臂61包含一桿側臂62及一可獨立於桿側臂62轉動的缸側臂63(參見圖19)。As shown in FIG. 18, in addition to the equalizer 64 and the arm 61, the brake device 10B further includes a linkage brake lever 40B and a biasing member 65 for previously moving in the opposite direction of the arm 61 during the braking operation. Apply a force to the direction. The arm 61 includes a lever side arm 62 and a cylinder side arm 63 that is rotatable independently of the lever side arm 62 (see Fig. 19).

缸側臂63因被桿側臂62施壓或如前所述被傳輸纜索21拉引而轉動，藉此向主缸32B之受壓部分32a施壓。如圖19所示，缸側臂63具有一缸施壓部分63a，一對上和下旋轉支承部分63d、63d，一受壓部分63c，及一受拉部分63e。桿 側臂62具有一旋轉支承部分63d、一桿側受壓部分62c、一施壓部分62a、一止動件62e、及一施力構件附接部分62f。The cylinder side arm 63 is rotated by the lever side arm 62 or pulled by the transmission cable 21 as described above, thereby pressing the pressure receiving portion 32a of the master cylinder 32B. As shown in Fig. 19, the cylinder side arm 63 has a cylinder pressing portion 63a, a pair of upper and lower rotation supporting portions 63d, 63d, a pressed portion 63c, and a tension portion 63e. Rod The side arm 62 has a rotation support portion 63d, a rod side pressure receiving portion 62c, a pressing portion 62a, a stopper 62e, and a biasing member attachment portion 62f.

如圖20所示，桿側臂62之施壓部分62a面向缸側臂63之受壓部分63c，且在桿側臂62之桿側受壓部分62c被均衡器64施壓時向受壓部分63c施壓。這導致桿側臂62和缸側臂63彼此一起轉動。As shown in Fig. 20, the pressing portion 62a of the rod side arm 62 faces the pressed portion 63c of the cylinder side arm 63, and is pressed toward the pressed portion when the rod side pressed portion 62c of the rod side arm 62 is pressed by the equalizer 64 63c pressure. This causes the lever side arm 62 and the cylinder side arm 63 to rotate together with each other.

桿側臂62之桿側受壓部分62c被施力構件65拉往均衡器64欲與均衡器64之臂施壓部分64c接觸。在此實例中，施力構件65是一具有一收縮力的彈性構件(例如彈簧)，且延伸於桿側臂62與主缸32B之間(參見圖18)。明確地說，桿側臂62之施力構件附接部分62f從桿側受壓部分62c往上突出(參見圖19)，且施力構件65之一端附接於施力構件附接部分62f。主缸32B具備一施力構件附接部分32j。如圖22所示，在主缸32B中，施力構件附接部分32j形成於後輪煞車纜索支撐部分32h之一中間部分往前延伸。其中施力構件附接部分32j是一往上突出的突出部，且施力構件65之另一端附接於施力構件附接部分32j。施力構件65依相反於當煞車作業進行時桿側臂62移動之方向的方向拉引桿側臂62之施力構件附接部分62f。The rod side pressure receiving portion 62c of the rod side arm 62 is pulled by the urging member 65 to the equalizer 64 to be in contact with the arm pressing portion 64c of the equalizer 64. In this example, the urging member 65 is an elastic member (for example, a spring) having a contracting force and extends between the rod side arm 62 and the master cylinder 32B (see Fig. 18). Specifically, the urging member attachment portion 62f of the rod side arm 62 protrudes upward from the rod side pressure receiving portion 62c (see FIG. 19), and one end of the urging member 65 is attached to the urging member attachment portion 62f. The master cylinder 32B is provided with a biasing member attachment portion 32j. As shown in Fig. 22, in the master cylinder 32B, the urging member attachment portion 32j is formed to extend forward in the middle portion of the rear wheel brake cable supporting portion 32h. The force applying member attachment portion 32j is a protruding portion that protrudes upward, and the other end of the urging member 65 is attached to the urging member attachment portion 32j. The urging member 65 pulls the urging member attachment portion 62f of the lever side arm 62 in a direction opposite to the direction in which the lever side arm 62 moves when the brake operation is performed.

如圖18和圖22所示，主缸32B在一背對於桿側臂62之止動件62e的位置具有一稍微往前***的定位部分32k。止動件62e與定位部分32k接觸(參見圖18)，且藉由限制桿側臂62被施力構件65拉引時之旋轉的方式決定桿側臂62之位 置。As shown in Figs. 18 and 22, the master cylinder 32B has a positioning portion 32k which is slightly raised forward at a position facing the stopper 62e of the lever side arm 62. The stopper 62e is in contact with the positioning portion 32k (see Fig. 18), and the position of the lever side arm 62 is determined by restricting the rotation of the lever side arm 62 when being pulled by the biasing member 65. Set.

缸側臂63之缸施壓部分63a、旋轉支承部分63d、63d及受拉部分63e分別與上文所述臂31之缸施壓部分31a、旋轉支承部分31d及受拉部分31e。也就是說，缸施壓部分63a與主缸32B之受壓部分32a接觸，且回應連動煞車桿40B之一操作力而向受壓部分32a施壓。桿側臂62之旋轉支承部分62d被設置在上和下旋轉支承部分對63d、63d之間。如圖19所示，旋轉支承部分63d及桿側臂62之旋轉支承部分62d分別具備孔63b、62b，且軸頸構件43穿過孔63b、62b以便使桿側臂62和缸側臂63可繞軸頸構件43旋轉。傳輸纜索21之內索21a被受拉部分63e固持，使得受拉部分63e會在前輪煞車桿20***作時受內索21a拉引。在圖18中，附接於內索21a之一端的拉動部分21c未示，且僅有內索21a以長條雙虛線示出。The cylinder pressing portion 63a, the rotation supporting portions 63d, 63d, and the tension portion 63e of the cylinder side arm 63 and the cylinder pressing portion 31a, the rotation supporting portion 31d, and the tension portion 31e of the arm 31 described above, respectively. That is, the cylinder pressing portion 63a comes into contact with the pressed portion 32a of the master cylinder 32B, and applies pressure to the pressure receiving portion 32a in response to an operating force of the interlocking lever 40B. The rotation support portion 62d of the lever side arm 62 is disposed between the pair of upper and lower rotation support portions 63d, 63d. As shown in Fig. 19, the rotary support portion 63d and the rotary support portion 62d of the lever side arm 62 are provided with holes 63b, 62b, respectively, and the journal member 43 passes through the holes 63b, 62b so that the lever side arm 62 and the cylinder side arm 63 can be Rotation around the journal member 43. The inner cable 21a of the transmission cable 21 is held by the tension portion 63e, so that the tension portion 63e is pulled by the inner cable 21a when the front wheel brake lever 20 is operated. In Fig. 18, the pulling portion 21c attached to one end of the inner cable 21a is not shown, and only the inner cable 21a is shown in a long double dashed line.

如圖19或圖20所示，均衡器64有一定位在其中心的旋轉支承部分64a、一被提供在離開旋轉支承部分64a之一位置的纜索附接部分64b、一同樣被提供在離開旋轉支承部分64a之一位置的臂施壓部分64c、及一***部分64f。後輪煞車纜索11之接合部分11d與前述旋轉構件42之纜索附接部分42b同樣被纜索附接部分64b固持(參見圖18或圖20)。後輪煞車纜索11藉由螺旋彈簧11c(參見圖1)之彈性力拉引纜索附接部分64b。旋轉支承部分64a是一孔，軸頸構件64穿過此孔。均衡器64可繞軸頸構件46旋轉。如圖20所示，***部分64f依背對於纜索附接部分64b的方向從旋轉支承 部分64a***。臂施壓部分64c形成於***部分64f之一與桿側臂62之桿側受壓部分62c相對的壁部分上。臂施壓部分64c被定位在橫跨旋轉支承部分64a與纜索附接部分64b相對之側上且與桿側臂62之桿側受壓部分62c接觸。當纜索附接部分64b被後輪煞車纜索11拉引時，一繞軸頸構件46的旋轉力作用於均衡器64上。因此，臂施壓部分64c向桿側受壓部分62c施壓。As shown in Fig. 19 or Fig. 20, the equalizer 64 has a rotary support portion 64a positioned at its center, a cable attachment portion 64b provided at a position away from the rotary support portion 64a, and a same also provided away from the rotary support. An arm pressing portion 64c at one position of the portion 64a, and a raised portion 64f. The engaging portion 11d of the rear wheel brake cable 11 is held by the cable attachment portion 64b as well as the cable attachment portion 42b of the aforementioned rotating member 42 (see Fig. 18 or Fig. 20). The rear wheel brake cable 11 pulls the cable attachment portion 64b by the elastic force of the coil spring 11c (see Fig. 1). The rotary bearing portion 64a is a hole through which the journal member 64 passes. The equalizer 64 is rotatable about the journal member 46. As shown in Fig. 20, the raised portion 64f is rotatably supported in a direction away from the cable attachment portion 64b. Part 64a is raised. The arm pressing portion 64c is formed on a wall portion of one of the swelled portions 64f opposite to the rod-side pressure receiving portion 62c of the rod side arm 62. The arm pressing portion 64c is positioned on the side opposite to the cable attachment portion 64b across the rotation support portion 64a and is in contact with the rod side pressure receiving portion 62c of the lever side arm 62. When the cable attachment portion 64b is pulled by the rear wheel brake cable 11, a rotational force about the journal member 46 acts on the equalizer 64. Therefore, the arm pressing portion 64c presses the rod side pressure receiving portion 62c.

在本實例中，如圖21所示，連接***部分64f之中心P1、旋轉支承部分64a之中心P2及纜索附接部分64b之中心P3的線係為大致平直的(圖21中之直線L3)。內索11a依一大致垂直於直線L3之方向(圖中所示方向V1)拉引纜索附接部分64b。臂施壓部分64c依一大致垂直於直線L3之方向(圖中所示方向V2)向桿側臂62之桿側受壓部分62c施壓。In the present example, as shown in Fig. 21, the line P1 of the connection ridge portion 64f, the center P2 of the rotation support portion 64a, and the center P3 of the cable attachment portion 64b are substantially straight (the straight line L3 in Fig. 21). ). The inner cable 11a pulls the cable attachment portion 64b in a direction substantially perpendicular to the straight line L3 (direction V1 shown in the drawing). The arm pressing portion 64c presses the rod side pressure receiving portion 62c of the lever side arm 62 in a direction substantially perpendicular to the straight line L3 (direction V2 shown in the drawing).

如圖18所示，連動煞車桿40B有一用於將均衡器64之旋轉量限制為不超過一預設量的止動件40i。圖23是一連動煞車桿40B之基部40c、40d的正視圖。如圖所示，止動件40i是一從基部40d朝基部40c突出的突出部。如圖18所示，止動件40i係一形成於一在當連動煞車桿40B***作時均衡器64之臂施壓部分64c移動之方向中稍微離開臂施壓部分64c的位置。As shown in Fig. 18, the interlocking lever 40B has a stopper 40i for limiting the amount of rotation of the equalizer 64 to a predetermined amount. Figure 23 is a front elevational view of the base portions 40c, 40d of a linkage brake lever 40B. As shown, the stopper 40i is a projection that protrudes from the base portion 40d toward the base portion 40c. As shown in Fig. 18, the stopper 40i is formed at a position slightly apart from the arm pressing portion 64c in the direction in which the arm pressing portion 64c of the equalizer 64 is moved when the interlocking lever 40B is operated.

今說明煞車裝置10B之操作。圖24和圖25是用來解釋當連動煞車桿40B***作時煞車裝置10B之操作的圖。圖26是一用來解釋當前輪煞車桿20***作時煞車裝置10B之操作的圖。圖27是一用來解釋當後輪煞車纜索11之內索11a 未連接時煞車裝置10B之操作的圖。圖28是一用來解釋在油料從液壓路徑12漏洩之情況中煞車裝置10B之操作的圖。在這些圖式中，主缸32B和連動煞車桿40B被簡化，且主缸32B之旋轉限制部分32c及連動煞車桿40B之止動件40f未示。後輪煞車纜索11之內索11a以長條雙虛線示出。The operation of the brake device 10B will now be described. 24 and 25 are diagrams for explaining the operation of the brake device 10B when the interlocking brake lever 40B is operated. Fig. 26 is a view for explaining the operation of the brake device 10B when the current rim lever 20 is operated. Figure 27 is a view for explaining the inner cable 11a of the rear wheel brake cable 11 A diagram of the operation of the brake device 10B when not connected. Figure 28 is a diagram for explaining the operation of the brake device 10B in the case where the oil leaks from the hydraulic path 12. In these drawings, the master cylinder 32B and the interlocking brake lever 40B are simplified, and the rotation restricting portion 32c of the master cylinder 32B and the stopper 40f of the interlocking brake lever 40B are not shown. The inner cable 11a of the rear wheel brake cable 11 is shown by a long double dashed line.

首先參照圖24和圖25說明當連動煞車桿40B***作時煞車裝置10B之操作。當連動煞車桿40B如圖24所示被拉往握把4b且開始轉動時，均衡器64開始與連動煞車桿40B一起依車輛寬度之橫向方向(圖中所示方向W1)移動。此時均衡器64之纜索附接部分64b將後輪煞車纜索11之內索11a依車輛寬度方向往外拉引，且臂施壓部分64c向桿側臂62之桿側受壓部分62c施壓。依此方式，後輪煞車17開始被作動。First, the operation of the brake device 10B when the interlocking brake lever 40B is operated will be described with reference to Figs. 24 and 25. When the interlocking lever 40B is pulled to the grip 4b as shown in Fig. 24 and starts to rotate, the equalizer 64 starts moving together with the interlocking lever 40B in the lateral direction of the vehicle width (direction W1 shown in the drawing). At this time, the cable attachment portion 64b of the equalizer 64 pulls the inner cable 11a of the rear wheel brake cable 11 outward in the vehicle width direction, and the arm pressing portion 64c presses the rod side pressure receiving portion 62c of the lever side arm 62. In this way, the rear wheel brake 17 begins to be actuated.

另一方面，由於施力構件65事先已拉引桿側臂62之施力構件附接部分62f，前輪煞車14不會開始作動。也就是說，施力構件65依相反於均衡器64向桿側臂62施壓之方向的方向拉引桿側臂62之施力構件附接部分62f。因此，桿側臂62和缸側臂63在施力構件65之驅策力與均衡器64之臂施壓部分64c用以推動桿側受壓部分62c之力彼此平衡之前不會轉動。故前輪煞車14在連動煞車桿40B剛開始***作之時不會馬上被作動。On the other hand, since the urging member 65 has previously pulled the urging member attachment portion 62f of the lever side arm 62, the front wheel brake 14 does not start to operate. That is, the urging member 65 pulls the urging member attachment portion 62f of the lever side arm 62 in a direction opposite to the direction in which the equalizer 64 presses the lever side arm 62. Therefore, the lever side arm 62 and the cylinder side arm 63 do not rotate until the urging force of the urging member 65 and the arm pressing portion 64c of the equalizer 64 are used to urge the lever side pressure receiving portion 62c to balance each other. Therefore, the front wheel brake 14 is not immediately actuated when the interlocking brake lever 40B is initially operated.

當連動煞車桿40B如圖25所示被更進一步拉往握把4b時，且當均衡器64用以推動桿側臂62之力大於施力構件65之力時，桿側臂62和缸側臂63彼此一起轉動，且缸側臂63 之缸施壓部分63a向主缸32B之受壓部分32a施壓。依此方式，前輪煞車14亦被作動。When the interlocking lever 40B is further pulled toward the grip 4b as shown in Fig. 25, and when the equalizer 64 is used to urge the lever side arm 62 to a greater force than the biasing member 65, the lever side arm 62 and the cylinder side The arms 63 rotate together with each other, and the cylinder side arms 63 The cylinder pressing portion 63a presses the pressure receiving portion 32a of the master cylinder 32B. In this way, the front wheel brake 14 is also actuated.

均衡器64被連動煞車桿40B支撐的旋轉支承部分64a係定位在臂施壓部分64c與纜索附接部分64b之間(參見圖21)。連動煞車桿40B之一操作力被劃分為一從纜索附接部分64b輸入到後輪煞車17的力(纜索附接部分64b拉引內索11a的力)及一從臂施壓部分64c輸入到前輪煞車14的力(臂施壓部分64c向桿側臂62施加的力)。區分比例係由從旋轉支承部分64a之中心P2到纜索附接部分64b之中心P3的距離與旋轉支承部分64a之中心P2到臂施壓部分64c的距離的比例決定。因此，均衡器64之區分比例在連動煞車桿40B之旋轉全程中大致恆定。The equalizer 64 is positioned between the arm pressing portion 64c and the cable attaching portion 64b by the rotating support portion 64a supported by the interlocking lever 40B (see Fig. 21). One of the operating forces of the interlocking brake lever 40B is divided into a force input from the cable attachment portion 64b to the rear wheel brake 17 (the force at which the cable attachment portion 64b pulls the inner cable 11a) and a input from the arm pressing portion 64c to The force of the front wheel brake 14 (the force applied by the arm pressing portion 64c to the lever side arm 62). The division ratio is determined by the ratio of the distance from the center P2 of the rotation support portion 64a to the center P3 of the cable attachment portion 64b to the distance from the center P2 of the rotation support portion 64a to the arm pressing portion 64c. Therefore, the division ratio of the equalizer 64 is substantially constant throughout the rotation of the interlocking brake lever 40B.

接下來參照圖26說明煞車裝置10B之操作。當前輪煞車桿20被拉往握把4a時(參見圖3)，傳輸纜索21之內索21a將缸側臂63之受拉部分63e拉往車輛寬度方向(圖中所示方向W2)中之中心。依此方式，缸側臂63之缸施壓部分63a如圖26所示向主缸32B之受壓部分32a施壓藉以作動前輪煞車14。此時缸側臂63之受壓部分63c從桿側臂62之施壓部分62a移開，且桿側臂62和連動煞車桿40B維持在各自的位置。Next, the operation of the brake device 10B will be described with reference to FIG. When the front rim lever 20 is pulled toward the grip 4a (see Fig. 3), the inner cable 21a of the transmission cable 21 pulls the tension portion 63e of the cylinder side arm 63 toward the vehicle width direction (direction W2 shown in the drawing). center. In this manner, the cylinder pressing portion 63a of the cylinder side arm 63 presses the pressure receiving portion 32a of the master cylinder 32B to actuate the front wheel brake 14 as shown in FIG. At this time, the pressed portion 63c of the cylinder side arm 63 is removed from the pressing portion 62a of the lever side arm 62, and the lever side arm 62 and the interlocking brake lever 40B are maintained at their respective positions.

接下來參照圖27說明煞車裝置10B之操作。當連動煞車桿40B在後輪煞車纜索11之內索11a未連接的狀態下被拉往握把4b時，均衡器64之旋轉支承部分64a依車輛寬度方向往外移動。此時均衡器64不用抵抗臂施壓部分64c從桿側 臂62之桿側受壓部分62c接收之反作用力而轉動。因此，桿側臂62和缸側臂63維持其位置。依此方式，有可能在後輪煞車纜索11之內索11a未連接時連動煞車桿40B***作的情況中防止僅有前輪煞車14作動。Next, the operation of the brake device 10B will be described with reference to FIG. When the interlocking brake lever 40B is pulled to the grip 4b in a state where the inner cable 11a of the rear wheel brake cable 11 is not connected, the rotary support portion 64a of the equalizer 64 moves outward in the vehicle width direction. At this time, the equalizer 64 does not need to resist the arm pressing portion 64c from the rod side. The lever side of the arm 62 is rotated by the reaction force received by the pressed portion 62c. Therefore, the lever side arm 62 and the cylinder side arm 63 maintain their positions. In this manner, it is possible to prevent only the front wheel brake 14 from being actuated in the case where the interlocking brake lever 40B is operated when the inner cable 11a of the rear wheel brake cable 11 is not connected.

接下來參照圖28說明煞車裝置10B之操作。當連動煞車桿40B在油料從液壓路徑12漏洩的情況中被拉往握把4b時，如圖24所示之案例，均衡器64在均衡器64之臂施壓部分64c向桿側臂62之桿側受壓部分62c施壓的力與施力構件65之驅策力彼此平衡之前僅只拉引後輪煞車纜索11。隨後，當連動煞車桿40B被更進一步拉往握把4b時，均衡器64之臂施壓部分64c從桿側臂62之桿側受壓部分62c接收的反作用力無法變成大於施力構件65之驅策力或更高。因此，均衡器64會被後輪煞車纜索11拉引而轉動。然後如圖28所示，均衡器64之臂施壓部分64c變成與事先提供在臂施壓部分64c前方的止動件40i接觸，藉此限制均衡器64之更進一步旋轉。因此，均衡器64將後輪煞車纜索11依車輛寬度方向更進一步往外拉，允許後輪煞車17更進一步施加一制動力。Next, the operation of the brake device 10B will be described with reference to FIG. When the interlocking brake lever 40B is pulled to the grip 4b in the case where the oil leaks from the hydraulic path 12, as in the case shown in Fig. 24, the equalizer 64 is biased toward the lever side arm 62 at the arm pressing portion 64c of the equalizer 64. The rear wheel brake cable 11 is only pulled before the force applied by the rod side pressed portion 62c and the urging force of the urging member 65 are balanced with each other. Subsequently, when the interlocking lever 40B is further pulled toward the grip 4b, the reaction force received by the arm pressing portion 64c of the equalizer 64 from the rod side pressure receiving portion 62c of the lever side arm 62 cannot become larger than the biasing member 65. Driven or higher. Therefore, the equalizer 64 is pulled by the rear wheel brake cable 11 to rotate. Then, as shown in Fig. 28, the arm pressing portion 64c of the equalizer 64 becomes in contact with the stopper 40i previously provided in front of the arm pressing portion 64c, thereby restricting further rotation of the equalizer 64. Therefore, the equalizer 64 pulls the rear wheel brake cable 11 further outward in the vehicle width direction, allowing the rear wheel brake 17 to further apply a braking force.

在上述煞車裝置10B中，均衡器64係用來當作一將連動煞車桿40B之一操作力輸入到後輪煞車17和前輪煞車14的構件。均衡器64將連動煞車桿40B之一操作力劃分為一輸入到後輪煞車17的力及一輸入到前輪煞車14的力，其區分比例係由從均衡器64之旋轉支承部分64a之中心到臂施壓部分64c的距離及到纜索附接部分64b的距離決定。因此， 即使是在內索11a例如因老化而變成稍微加長的情況中，連動煞車桿40B之一操作力的區分比例不會被內索11a之老化現象影響，使得初始比例得以維持。In the above-described brake device 10B, the equalizer 64 is used as a member for inputting an operation force of the interlocking brake lever 40B to the rear wheel brake 17 and the front wheel brake 14. The equalizer 64 divides the operating force of one of the linked brake levers 40B into a force input to the rear wheel brake 17 and a force input to the front wheel brake 14, the division ratio being from the center of the rotary support portion 64a of the equalizer 64 to The distance of the arm pressing portion 64c and the distance to the cable attachment portion 64b are determined. therefore, Even in the case where the inner cable 11a becomes slightly lengthened, for example, due to aging, the division ratio of the operating force of one of the interlocking brake levers 40B is not affected by the aging phenomenon of the inner cable 11a, so that the initial ratio is maintained.

在上述煞車裝置10、10A和10B中，騎士對前輪煞車桿20進行的操作係由傳輸纜索21傳輸到連動煞車桿40。但騎士對前輪煞車桿20進行的操作可為藉由一桿傳輸到連動煞車桿40。In the above-described brake devices 10, 10A and 10B, the operation of the front wheel brake lever 20 by the knight is transmitted from the transmission cable 21 to the interlocking brake lever 40. However, the knight's operation on the front wheel brake lever 20 can be transmitted to the interlocking brake lever 40 by one lever.

圖29是一依據此實施例之煞車裝置10C的簡圖。圖30是一沿圖29之線A-A取得的剖面圖。圖31是一沿圖29之線B-B取得的剖面圖。圖32是一沿圖29之線C-C取得的剖面圖。在這些圖式中，與前述相似的部分將被賦予相似參考數字且不再次說明。Figure 29 is a schematic view of a brake device 10C according to this embodiment. Figure 30 is a cross-sectional view taken along line A-A of Figure 29. Figure 31 is a cross-sectional view taken along line B-B of Figure 29. Figure 32 is a cross-sectional view taken along line C-C of Figure 29. In the drawings, parts similar to those described above will be given similar reference numerals and will not be described again.

在煞車裝置10C中，如圖29所示，前述連動煞車桿40被提供在左車把4上，且一前輪煞車桿20C被提供在右車把4上。煞車裝置10C包含一當作操作力傳輸構件的桿51，此構件將前輪煞車桿20C之操作傳輸到前輪煞車致動機構30。桿51係由一剛性材料(例如金屬)製成。桿51可為平直或者可在一中間部分稍微彎曲。該桿可被一用來覆蓋車體前部的包覆物覆蓋，或者可被設置在一儀表譬如速度計後方，以便不暴露於外界。In the brake device 10C, as shown in Fig. 29, the aforementioned interlocking lever 40 is provided on the left handlebar 4, and a front wheel lever 20C is provided on the right handlebar 4. The brake device 10C includes a lever 51 as an operating force transmitting member that transmits the operation of the front wheel brake lever 20C to the front wheel brake actuating mechanism 30. The rod 51 is made of a rigid material such as metal. The rod 51 can be straight or can be slightly curved in an intermediate portion. The rod may be covered by a covering for covering the front of the vehicle body or may be placed behind a meter such as a speedometer so as not to be exposed to the outside.

桿51被設置為從車把4之一者延伸到另一者。桿51之一端耦接於臂31之受拉部分31e，且不同於前述傳輸纜索21，桿51與受拉部分31e間之相對移動會受限制。The rod 51 is arranged to extend from one of the handlebars 4 to the other. One end of the rod 51 is coupled to the tension portion 31e of the arm 31, and unlike the aforementioned transmission cable 21, the relative movement between the rod 51 and the tension portion 31e is restricted.

明確地說，如圖30所示，一用於耦接桿51之末端與受拉 部分31e的聯結器52被提供在桿51之末端。聯結器52包含一基部52a及一對從基部52a垂直延伸的板52b、52b。桿51穿過一形成於基部52a中之孔52c。一直徑大於孔52c的接合部分51a形成於桿51之末端。接合部分51a設置在聯結器52內，且被基部52a及由板對52b、52b往內變形而形成之突出部52d、52d固持。受拉部分31e設置在板對52b、52b之間，且其藉由一銷53耦接。也就是說，在板對52b、52b及受拉部分31e每一者中有一大小與銷53之直徑相當的孔形成，且銷53穿過這些孔。一開尾銷54***銷53之一端以防銷53滑脫。依此方式，桿51和受拉部分31e以使其間相對移動受到限制的狀態耦接在一起。其中在板對52b、52b每一者中有一大小與銷53之直徑相當的孔形成。然亦可如同前述在拉動部分21c中形成一用於煞車裝置10之傳輸纜索21的長形孔(參見圖14)，用長形孔取代板對52b、52b之孔。Specifically, as shown in FIG. 30, one is used for the end and the tension of the coupling rod 51. A coupler 52 of portion 31e is provided at the end of the rod 51. The coupler 52 includes a base portion 52a and a pair of plates 52b, 52b extending perpendicularly from the base portion 52a. The rod 51 passes through a hole 52c formed in the base 52a. An engaging portion 51a having a diameter larger than the hole 52c is formed at the end of the rod 51. The joint portion 51a is provided in the coupler 52, and is held by the base portion 52a and the projecting portions 52d, 52d formed by the inward deformation of the pair of plates 52b, 52b. The tensioned portion 31e is disposed between the pair of plates 52b, 52b, and is coupled by a pin 53. That is, a hole having a size corresponding to the diameter of the pin 53 is formed in each of the pair of plates 52b, 52b and the tensioned portion 31e, and the pin 53 passes through the holes. An open end pin 54 is inserted into one end of the pin 53 to prevent the pin 53 from slipping off. In this manner, the rod 51 and the tension portion 31e are coupled together in a state in which relative movement therebetween is restricted. Therein, a hole having a size corresponding to the diameter of the pin 53 is formed in each of the pair of plates 52b, 52b. Alternatively, as shown above, an elongated hole for the transmission cable 21 of the brake device 10 is formed in the pulling portion 21c (see Fig. 14), and the hole of the pair 52b, 52b is replaced with an elongated hole.

如圖29所示，前輪煞車桿20C被一附接於車把4的附接構件23C支撐為可旋轉。也就是說，如同前述前輪煞車桿20，支承部分20c被提供在前輪煞車桿20C之基部。軸頸構件24(例如螺栓)穿過一形成於支承部分20c中之孔及一形成於附接構件23C中之孔，且前輪煞車桿20C可繞軸頸構件24旋轉。As shown in FIG. 29, the front wheel brake lever 20C is rotatably supported by an attachment member 23C attached to the handlebar 4. That is, like the aforementioned front wheel brake lever 20, the support portion 20c is provided at the base of the front wheel brake lever 20C. The journal member 24 (e.g., a bolt) passes through a hole formed in the support portion 20c and a hole formed in the attachment member 23C, and the front wheel lever 20C is rotatable about the journal member 24.

除了支承部分20c，一棒耦接部分20d被提供在前輪煞車桿20C之基部。桿51在不僅其對於臂31之受拉部分31e的相對移動受到限制還有其對於棒耦接部分20d的相對移動受 到限制之狀態下被耦接。桿51具備一用於調整棒耦接部分20d與受拉部分31e間之距離的調整機構55(參見圖31)。In addition to the support portion 20c, a rod coupling portion 20d is provided at the base of the front wheel brake lever 20C. The rod 51 is restricted not only by its relative movement to the tension portion 31e of the arm 31 but also by its relative movement to the rod coupling portion 20d. It is coupled to the limit state. The lever 51 is provided with an adjustment mechanism 55 (see Fig. 31) for adjusting the distance between the rod coupling portion 20d and the tension portion 31e.

明確地說，如圖31所示，棒51之另一端藉由一聯結器56耦接於棒耦接部分20d。如同前述聯結器52，聯結器56包含一具備讓桿51穿過之一孔56c的基部56a及一對板56b、56b。棒耦接部分20d設置在板對56b、56b之間，且其藉由一銷57耦接。一開尾銷58***銷57之遠端以防銷57滑脫。一螺紋51b形成於桿51之另一端的外周表面上，且基部56a被固持在裝配於螺紋51b上的二個螺帽55a、55b之間。Specifically, as shown in FIG. 31, the other end of the rod 51 is coupled to the rod coupling portion 20d by a coupler 56. Like the aforementioned coupler 52, the coupler 56 includes a base portion 56a and a pair of plates 56b, 56b having a rod 51 passing through a hole 56c. The rod coupling portion 20d is disposed between the pair of plates 56b, 56b and is coupled by a pin 57. An open tail pin 58 is inserted into the distal end of the pin 57 to prevent the pin 57 from slipping off. A thread 51b is formed on the outer peripheral surface of the other end of the rod 51, and the base portion 56a is held between the two nuts 55a, 55b fitted to the thread 51b.

依此方式，桿51藉由聯結器56耦接於棒耦接部分20d。桿51與棒耦接部分20d之間的相對移動受到限制。因此，在煞車裝置10C中，當連動煞車桿40***作往握把4b旋轉時，連動煞車桿40之移動傳輸到前輪煞車桿20C藉以使前輪煞車桿20C亦往握把4a旋轉。依此方式，有可能在連動煞車桿40和前輪煞車桿20C被成功地操作的情況中提升此二者之操作性。也就是說，當在連動煞車桿40往握把4b旋轉之中途開始前輪煞車桿20C之一操作時，前輪煞車桿20C之移動立即傳輸到臂31，使得前輪煞車14可被一施加於前輪煞車桿20C的操作力作動。In this manner, the rod 51 is coupled to the rod coupling portion 20d by the coupling 56. The relative movement between the rod 51 and the rod coupling portion 20d is limited. Therefore, in the brake device 10C, when the interlocking lever 40 is operated to rotate toward the grip 4b, the movement of the interlocking lever 40 is transmitted to the front wheel lever 20C so that the front wheel lever 20C is also rotated toward the grip 4a. In this way, it is possible to enhance the operability of both of the linked brake lever 40 and the front wheel brake lever 20C in the case where the operation is successful. That is, when one of the front wheel brake levers 20C is started while the interlocking brake lever 40 is rotated toward the grip 4b, the movement of the front wheel brake lever 20C is immediately transmitted to the arm 31, so that the front wheel brake 14 can be applied to the front wheel brake The operating force of the lever 20C is actuated.

連動煞車桿40、前輪煞車桿20C、臂31、及其他部分的尺寸和位置經訂定致使當連動煞車桿40***作時(當連動煞車桿40被移動至與握把4b接觸時)，前輪煞車桿20C所作的移動量不超過前輪煞車桿20C之可動範圍(從操作前之位置到其與握把4a發生接觸之位置的範圍)。舉例來說，臂 31和前輪煞車桿20C的尺寸經訂定致使從前輪煞車桿20C之旋轉中心(軸頸構件24之中心)到棒耦接部分20d的距離大於從臂31之旋轉中心(軸頸構件43之中心)到受拉部分31e的距離。The size and position of the interlocking brake lever 40, the front wheel brake lever 20C, the arm 31, and other portions are set such that when the interlocking brake lever 40 is operated (when the interlocking brake lever 40 is moved to contact with the grip 4b), the front wheel The amount of movement of the brake lever 20C does not exceed the movable range of the front wheel brake lever 20C (the range from the position before the operation to the position where it comes into contact with the grip 4a). For example, the arm The size of the front wheel brake lever 20C and the front wheel brake lever 20C are set such that the distance from the center of rotation of the front wheel brake lever 20C (the center of the journal member 24) to the rod coupling portion 20d is greater than the center of rotation of the slave arm 31 (the center of the journal member 43) ) the distance to the tension portion 31e.

如圖29和圖31所示，前述調整機構55係由二個螺帽55a、55b及螺紋51b構成，且藉由轉動螺紋51b來調整棒耦接部分20d與受拉部分31e之間的距離。也就是說，藉由將螺紋51b相對於螺帽55a、55b轉動以移動螺帽55a、55b在桿51上之位置，聯結器56之附接位置被依桿51之縱向方向移動藉以調整棒耦接部分20d與受拉部分31e之間的距離。As shown in Figs. 29 and 31, the adjustment mechanism 55 is composed of two nuts 55a, 55b and a thread 51b, and the distance between the rod coupling portion 20d and the tension portion 31e is adjusted by rotating the thread 51b. That is, by rotating the thread 51b relative to the nut 55a, 55b to move the position of the nut 55a, 55b on the rod 51, the attachment position of the coupler 56 is moved in the longitudinal direction of the rod 51 to adjust the rod coupling. The distance between the connecting portion 20d and the tension portion 31e.

前輪煞車桿20C構成為在桿51連接之前的狀態下可依離開握把4a之方向旋轉超過前輪煞車桿20C之初始位置(參見圖29)、亦即前輪煞車桿20C未***作時的位置(圖29所示前輪煞車桿20C之位置)。前輪煞車桿20C之初始位置可經由用調整機構55調整棒耦接部分20d與受拉部分31e間之距離而設定在前輪煞車桿20C之可動範圍內一適當位置。也就是說，前輪煞車桿20C之抓握部分20a的初始位置可因轉動桿51、移動聯結器56在桿51上之附接位置、及加大棒耦接部分20d與受拉部分31e間之距離而被帶到較靠近握把4a。相對而言，抓握部分20a之初始位置可因減小棒耦接部分20d與受拉部分31e間之距離而被帶到離開握把4a。The front wheel brake lever 20C is configured to be rotated in a direction away from the grip 4a beyond the initial position of the front wheel brake lever 20C (see FIG. 29) in a state before the lever 51 is connected, that is, a position when the front wheel brake lever 20C is not operated ( Figure 29 shows the position of the front wheel brake lever 20C). The initial position of the front wheel brake lever 20C can be set at an appropriate position within the movable range of the front wheel brake lever 20C via the adjustment mechanism 55 adjusting the distance between the bar coupling portion 20d and the tension portion 31e. That is, the initial position of the grip portion 20a of the front wheel brake lever 20C may be due to the rotation lever 51, the attachment position of the movement coupling 56 on the rod 51, and the between the enlarged rod coupling portion 20d and the tension portion 31e. The distance is brought closer to the grip 4a. In contrast, the initial position of the grip portion 20a can be brought away from the grip 4a by reducing the distance between the rod coupling portion 20d and the tension portion 31e.

在一些案例中，車把4上之附接構件23C的附接位置會因為製造誤差或類似因素而未對準，且因此前輪煞車桿20C之初始位置會離握把4a太近或太遠。又，在此等案例中， 抓持部分20a之初始位置可藉由調整棒耦接部分20d與受拉部分31e間之距離而被適當設定。In some cases, the attachment position of the attachment member 23C on the handlebar 4 may be misaligned due to manufacturing tolerances or the like, and thus the initial position of the front wheel brake lever 20C may be too close or too far from the grip 4a. Also, in these cases, The initial position of the grip portion 20a can be appropriately set by adjusting the distance between the rod coupling portion 20d and the tension portion 31e.

如圖32所示，煞車裝置10C具備一用於依拉引桿51之方向推動前輪煞車桿20C的彈簧29。在所述實例中，一彈簧固持部分23a被提供在附接構件23C面向前輪煞車桿20C基部之一位置。彈簧29之一端裝在一形成於彈簧固持部分23a中的凹穴23b內，且另一端裝在一形成於前輪煞車桿20C之基部中的凹穴20e內。彈簧29是一壓縮彈簧，且依使前輪煞車桿20C之基部和彈簧固持部分23a彼此分開的方向施加一力。彈簧29防止前輪煞車桿20C晃蕩發出聲響。As shown in Fig. 32, the brake device 10C is provided with a spring 29 for pushing the front wheel lever 20C in the direction of the pull rod 51. In the example, a spring retaining portion 23a is provided at a position where the attachment member 23C faces the base of the front rim lever 20C. One end of the spring 29 is fitted in a recess 23b formed in the spring holding portion 23a, and the other end is fitted in a recess 20e formed in the base of the front rim lever 20C. The spring 29 is a compression spring and exerts a force in a direction in which the base of the front wheel brake lever 20C and the spring holding portion 23a are separated from each other. The spring 29 prevents the front wheel brake lever 20C from swaying to make a sound.

在上述煞車裝置10C中，桿51係當作一操作力傳輸構件。因此，有可能更進一步減小一操作力在一從前輪煞車桿到前輪煞車致動機構之傳輸路徑中的傳輸損失。由於桿相較於纜索並不會隨著時間經過而變長，不需要使用者進行長度調整工作。因此，有可能防止使用者作出不當調整。In the above-described brake device 10C, the lever 51 is regarded as an operation force transmission member. Therefore, it is possible to further reduce the transmission loss of an operating force in a transmission path from the front rim brake lever to the front wheel brake actuation mechanism. Since the rod does not become longer than the cable over time, the user does not need to perform the length adjustment work. Therefore, it is possible to prevent the user from making improper adjustments.
