Description

鼓煞自由間隙之自動補償裝置 Automatic compensation device for drumstick free gap

本創作係有關於一種煞車自由間隙的自動補償裝置，特別是有關於一種鼓式煞車的自由間隙之維持煞車系統。 This creation is about an automatic compensation device for the free clearance of the brakes, in particular, a maintenance brake system for the free play of a drum brake.

習用鼓式煞車具有良好的自煞作用，且在產生相同煞車力矩的條件下，鼓式煞車之煞車鼓的直徑可以較碟式煞車之煞車碟的直徑小上許多，加上鼓式煞車具有零件成本低廉與維修方便等諸多優點，使得鼓式煞車被廣泛運用於汽車、機車、自行車或其它各式車輛的煞車系統當中。值得注意的是，鼓式煞車容易隨著煞車次數增加而造成其煞車蹄片磨耗，使得煞車蹄片與煞車鼓的間距擴大，遂導致用以帶動煞車蹄片之煞車線必須被拉動更長的距離才能使煞車蹄片接觸摩擦煞車鼓，換言之，使用者拉動煞車拉桿或踩踏煞車踏板之行程必須延長，方可獲得與煞車蹄片未磨耗前相同之煞車力。 The conventional drum brake has a good self-tapping effect, and under the condition of generating the same braking torque, the diameter of the drum of the drum brake can be much smaller than the diameter of the brake disc of the disc brake, and the drum brake has the parts. The low cost and convenient maintenance make the drum brakes widely used in the braking system of automobiles, locomotives, bicycles or other vehicles. It is worth noting that the drum brake is easy to wear the brake shoe with the increase of the number of brakes, which makes the distance between the brake shoe and the brake drum wide, and the brake line used to drive the brake shoe must be pulled longer. The distance can make the brake shoe contact the friction brake drum. In other words, the stroke of the user pulling the brake lever or stepping on the brake pedal must be extended to obtain the same braking force as before the brake shoe is not worn.

中華民國專利公告第549283號專利案揭示一種習用鼓式煞車裝置鼓式煞車裝置1，請參照圖1A所示，該鼓式煞車裝置1，包含一煞車把手11、一煞車單元12及一煞車線13，該煞車線13分別連接該煞車把手11及一螺桿131。其中，該煞車單元12包含一擺臂121，該擺臂121係樞接於該螺桿131並且透過一螺帽122定位，該螺帽122係螺合於該螺桿131。藉此，當使用者拉動該煞車把手11時，將一併帶動與該煞車把手11相連接之煞車線13，使得螺合於該螺桿131之螺帽122隨著該煞車線13產生位移並抵壓該 擺臂121，因此，該擺臂121將可驅動煞車蹄片(圖未繪示)向外撐開，以抵壓安裝於車輛輪圈之煞車鼓，進而產生煞車力。 The Patent No. 549283 of the Republic of China discloses a drum brake device 1 for a conventional drum type brake device. Referring to FIG. 1A, the drum brake device 1 includes a brake handle 11, a brake unit 12 and a brake line. 13. The brake line 13 is connected to the brake handle 11 and a screw 131, respectively. The brake unit 12 includes a swing arm 121 pivotally connected to the screw 131 and positioned through a nut 122. The nut 122 is screwed to the screw 131. Therefore, when the user pulls the brake handle 11, the brake wire 13 connected to the brake handle 11 is driven together, so that the nut 122 screwed to the screw 131 is displaced with the brake wire 13 Press The swing arm 121, therefore, the swing arm 121 spreads the driveable brake shoe (not shown) outward to press against the brake drum mounted on the vehicle rim, thereby generating braking force.

隨著使用時間的增加，所述煞車蹄片係逐漸磨損，使得煞車蹄片與煞車鼓的間距擴大，導致使用者必須拉動該煞車把手11之行程必須延長，方能使得煞車蹄片與煞車鼓發生接觸而產生煞車效果。據此，該習用鼓式煞車裝置1需仰賴人力旋動該螺帽122，迫使該擺臂121朝該煞車線13移動來將煞車蹄片略微向外撐開，使煞車蹄片與煞車鼓的間距形成與煞車蹄片尚未磨損前相同之準位，以維持該習用鼓式煞車裝置1之煞車效果。 As the use time increases, the brake shoe is gradually worn, so that the distance between the brake shoe and the brake drum is enlarged, so that the stroke of the user must pull the brake handle 11 must be extended, so that the brake shoe and the brake drum can be made. Contact occurs to produce a braking effect. Accordingly, the conventional drum brake device 1 relies on the human to rotate the nut 122, forcing the swing arm 121 to move toward the brake line 13 to slightly open the brake shoe, so that the brake shoe and the brake drum are The spacing is formed at the same level as before the brake shoe has not worn to maintain the braking effect of the conventional drum brake device 1.

然而，對於不熟悉車輛維護之使用者而言，通常係仰賴專業維修人員調整該螺帽122，因而無法在煞車蹄片係發生磨損後及時經由該螺帽122對該擺臂121進行迫緊調整，使得車輛之煞車力不足而造成煞車距離大幅增加，嚴重危害車輛之行駛安全性。再者，維修人員為了避免上述情形發生，時常替使用者大幅度旋動該螺帽122以將煞車蹄片與煞車鼓的間距縮到很小，讓該習用鼓式煞車裝置1在煞車蹄片磨損後仍能保有一定的煞車效果。惟，煞車蹄片與煞車鼓的間距過小會造成煞車操作過於靈敏，一旦使用者不小心觸動該煞車把手11之時，就可能產生不可預期的煞車行為(例如：輪胎鎖死打滑)而發生的意外。 However, for a user unfamiliar with the maintenance of the vehicle, the professional maintenance personnel are usually required to adjust the nut 122, so that the swing arm 121 cannot be tightly adjusted through the nut 122 after the brake shoe system is worn out. In order to make the vehicle's braking force insufficient, the braking distance is greatly increased, which seriously jeopardizes the driving safety of the vehicle. Moreover, in order to avoid the above situation, the maintenance personnel frequently rotate the nut 122 for the user to reduce the distance between the brake shoe and the brake drum to be small, so that the conventional drum brake device 1 is in the brake shoe. It can still maintain a certain braking effect after wear. However, if the distance between the brake shoe and the brake drum is too small, the brake operation may be too sensitive. Once the user accidentally touches the brake handle 11, the unintended braking behavior (for example, the tire locks and slips) may occur. accident.

為了解決上述問題，中華民國專利公告第549283號專利案另揭示了一種習用煞車自動調整裝置2，請參照圖1B所示，其可以應用於前述習用鼓式煞車裝置1當中，該習用煞車自動調整裝置2包含一觸動開關21、一動力源22一齒輪組23及一控制單元24。該觸動開關21與該煞車把手11相連設；該動力源22固定於該煞車單元12之擺臂121；該齒輪組23包含相互嚙合之一第一齒輪件231及一第二齒輪件232，該第一齒輪件231結合於該動力源22上並直接受到該動力源22所驅動，該第二齒輪件232係結合該煞車單元12之螺帽122，且該第二齒輪件232與該螺帽122是彼此連固呈現一體聯 動的狀態。該控制單元24分別耦接該觸動開關21及該動力源22。 In order to solve the above problem, the Patent Publication No. 549283 of the Republic of China discloses a conventional automatic brake adjusting device 2, which can be applied to the conventional drum brake device 1 as shown in FIG. 1B, which automatically adjusts the brake device. The device 2 includes a touch switch 21, a power source 22, a gear set 23 and a control unit 24. The trigger switch 21 is connected to the brake handle 11; the power source 22 is fixed to the swing arm 121 of the brake unit 12; the gear set 23 includes a first gear member 231 and a second gear member 232 that mesh with each other. The first gear member 231 is coupled to the power source 22 and directly driven by the power source 22, the second gear member 232 is coupled to the nut 122 of the brake unit 12, and the second gear member 232 and the nut 122 is a solid connection with each other Dynamic state. The control unit 24 is coupled to the touch switch 21 and the power source 22 respectively.

藉由設置該習用煞車自動調整裝置2，當煞車蹄片磨損使得煞車蹄片與煞車鼓的間距擴大時，使用者拉動該煞車把手11行程會延長，因此將觸壓到該觸壓開關21，與該觸壓開關21耦接之控制單元24係啟動該動力源22，該動力源22帶動該第一齒輪件231旋轉，進而一併帶動該第二齒輪件232及該螺帽122轉動，以迫使該擺臂121朝該煞車線13移動來將煞車蹄片略微向外撐開，使煞車蹄片與煞車鼓的間距形成與煞車蹄片尚未磨損前相同之準位。據此，該習用煞車自動調整裝置2能夠鼓式煞車的煞車蹄片與煞車鼓的間距保持定值，有效控制該習用鼓式煞車裝置1之煞車效果的變化幅度。 By setting the conventional brake automatic adjusting device 2, when the brake shoe wear is worn, the distance between the brake shoe and the brake drum is enlarged, the stroke of the user pulling the brake handle 11 is extended, and thus the touch switch 21 is pressed. The control unit 24 coupled to the touch switch 21 activates the power source 22, and the power source 22 drives the first gear member 231 to rotate, thereby driving the second gear member 232 and the nut 122 to rotate together. The swing arm 121 is forced to move toward the brake line 13 to slightly open the brake shoe, so that the distance between the brake shoe and the brake drum is the same as that before the brake shoe has not worn. Accordingly, the conventional brake automatic adjusting device 2 can maintain a constant value of the distance between the brake shoe and the brake drum of the drum brake, and effectively control the variation range of the braking effect of the conventional drum brake device 1.

惟，該習用煞車自動調整裝置2需要採用觸動開關21、動力源22及控制單元24等電子元件，使其具有成本高昂、故障率高與維修困難等缺點，由於成本較低與維修簡便係習用鼓式煞車的重要優點，設置該習用煞車自動調整裝置2將大幅降低鼓式煞車之市場價值，顯然不符合業界需求。再者，該動力源22必須固定於該煞車單元12之擺臂121，實際上在現有車輛的煞車系統中並未預留容置該動力源22的空間，且現有車輛的擺臂121亦無對應之結合部位可供該動力源22組裝，換言之，該習用煞車自動調整裝置2無法適用於市售車輛當中，不能單獨販售供使用者自行添購安裝，適用範圍將嚴重限縮。況且，該習用煞車自動調整裝置2還需要在煞車把手或煞車踏板的位置安裝該觸動開關21，並且以導線將該控制單元24分別耦接該觸動開關21及該動力源22，使得該習用煞車自動調整裝置2難以應用於車體空間受限之機車或自行車當中。 However, the conventional brake automatic adjusting device 2 needs to use electronic components such as the touch switch 21, the power source 22, and the control unit 24, so that it has disadvantages such as high cost, high failure rate, and difficulty in maintenance, and is low in cost and easy to maintain. The important advantage of the drum brake is that setting the brake automatic adjustment device 2 will greatly reduce the market value of the drum brake, which obviously does not meet the needs of the industry. In addition, the power source 22 must be fixed to the swing arm 121 of the brake unit 12, and actually the space for accommodating the power source 22 is not reserved in the brake system of the existing vehicle, and the swing arm 121 of the existing vehicle is not The corresponding joint portion can be assembled by the power source 22, in other words, the conventional brake automatic adjusting device 2 cannot be applied to a commercially available vehicle, and cannot be sold separately for the user to purchase and install, and the scope of application is severely limited. Moreover, the conventional brake adjusting device 2 also needs to install the touch switch 21 at the position of the brake handle or the brake pedal, and couple the control unit 24 to the touch switch 21 and the power source 22 by wires respectively, so that the conventional brake is used. The automatic adjustment device 2 is difficult to apply to a locomotive or bicycle in which the vehicle body space is limited.

The brake rocker arm 432 is pivoted with a pivot 431 as a pivot After the degree, the principle of the lever (this is the basic design principle of the brake system) can change the free gap between the surface of the drum 4 (not shown) and the inner wall surface of the corresponding brake drum 41; The tension spring 433 is disposed between the brake rocker arm 432 and the pivot 431, and functions to return the yaw brake rocker arm 432 to the original position (ie, the initial position of the brake rocker arm 432 when the vehicle is not braked); The sleeve nut 435 is screwed to the adjusting screw 434 of the yaw end portion 4321 of the brake rocker arm 432 to adjust the positioning of the screw 434 and adjust the working length of the adjusting screw 434 (please refer to FIG. 5 as well That is, the distance from the end face of the adjusting screw 434 that receives the pulling force of the brake to the yaw end portion 4321 of the adjusting rocker 432 to the yaw end portion 4321 of the braking rocker arm 432 is increased. Under normal setting, the longer the acting length, the braking arm 432 The smaller the initial angle A of the untwisted car, the larger the free gap of the drumstick 4).

本實施例之該自動補償裝置3包含：固定座31、外殼32、連接滑座33以及轉動導引機構34。固定座31係固設於設置該鼓煞4的該煞車鼓41之上，但不以此為限(例如，該固定座31也可固定於設置該鼓煞4的車體或車架5上)。外殼32係樞設於該固定座31，其內部具有一內徑腔室321；連接滑座33，係可沿著該內徑腔室321自由移動，連接滑座33的一端面嵌設一單向軸承331，並以該單向軸承331的內徑供該調整螺桿434嵌套後，使該調整螺桿434末端可轉動地卡接於該連接滑座33內，該連接滑座33的相對的另一端面具有一可自由擺動地連接該煞車導線42的連接部332。該轉動導引機構34係將互相對應套合的一導銷341和一包含彼此互相連接的直槽3421與斜槽3422之導槽342，其係分別設置於該外殼32與該連接滑座33之間的面對面的部位上，具體而言，該導槽342係設置於該連接滑座33之表面，該導銷341係設置於該外殼32上並對應嵌設至該導槽342內，當然在另一實施例中也可將該導銷341與該導槽342反置(即導銷341設置在該連接滑座33表面、導槽342設置在該外殼32上)，並調整該直槽3411與斜槽3422的順序及角度方向也可達成相同效果。 The automatic compensating device 3 of the present embodiment includes a fixing base 31, a housing 32, a connecting slider 33, and a rotation guiding mechanism 34. The fixing base 31 is fixed on the brake drum 41 on which the drum 4 is disposed, but not limited thereto (for example, the fixing base 31 can also be fixed on the vehicle body or the frame 5 on which the drum 4 is disposed. ). The outer casing 32 is pivotally disposed on the fixing base 31, and has an inner diameter chamber 321 therein; the connecting sliding seat 33 is freely movable along the inner diameter chamber 321 , and a single end surface of the connecting sliding seat 33 is embedded with a single After the adjusting screw 434 is inserted into the bearing 331 and the inner diameter of the one-way bearing 331 is nested, the end of the adjusting screw 434 is rotatably engaged in the connecting sliding seat 33, and the opposite side of the connecting sliding seat 33 The other end face has a connecting portion 332 that is swingably connected to the brake wire 42. The rotation guiding mechanism 34 is a guiding pin 341 and a guiding groove 342 including a straight groove 3421 and a chute 3422 which are mutually connected to each other, and are respectively disposed on the outer casing 32 and the connecting sliding seat 33. In particular, the guide groove 342 is disposed on the surface of the connecting slide 33. The guide pin 341 is disposed on the outer casing 32 and correspondingly embedded in the guide groove 342. In another embodiment, the guide pin 341 can also be opposite to the guide groove 342 (ie, the guide pin 341 is disposed on the surface of the connecting slide 33, and the guide groove 342 is disposed on the outer casing 32), and the straight groove is adjusted. The same effect can be achieved by the order of the 3411 and the chute 3422 and the angular direction.

續請參見圖5、圖6及圖7所示。根據上述結構之實施例，當 使用者以煞車把手或煞車踏板51對該煞車導線42輸入一煞車拉力P時，該煞車導線42拉動該連接滑座33往該煞車導線42的方向(圖5的右側)移動，該連接滑座33隨之帶動卡接於另一端的調整螺桿434同向移動，該調整螺桿434向該煞車導線42方向拉動時即可使該煞車搖臂432由該未煞車初始角度A(如圖5所示)轉動一偏擺角度C(如圖6所示)，同時該回拉彈簧433產生蓄能作用，其可使該鼓煞4的自由間隙消除並產生煞車作用。 Continue to see Figure 5, Figure 6, and Figure 7. According to the embodiment of the above structure, when When the user inputs a brake force P to the brake wire 42 by the brake handle or the brake pedal 51, the brake wire 42 pulls the connection slide 33 to the direction of the brake wire 42 (the right side of FIG. 5), and the connection slide 33, the adjusting screw 434 which is engaged with the other end is moved in the same direction, and the adjusting screw 434 is pulled in the direction of the braking wire 42 to make the braking arm 432 from the initial angle A of the untweeted vehicle (as shown in FIG. 5). Turning a yaw angle C (as shown in FIG. 6), the pull-back spring 433 generates an energy storage function which can eliminate the free play of the drum 4 and generate a braking effect.

值得一提的是，當該鼓煞4的來令片(或稱煞車蹄片)未磨耗時，對該煞車導線42輸入一煞車拉力P即可消除該鼓煞4的自由間隙並取得足夠的煞車力，且當該煞車拉力P移除後，該煞車搖臂432受到該回拉彈簧433回復力拉回原未煞車初始角度A的位置，也使得該調整螺桿434、該連接滑座33及該煞車導線42回復原來煞車前的位置，此時該連接滑座33的往復移動行程即對應於固定不動的該導銷341之該導槽342之直槽3421的範圍內移動，因此該連接滑座33只會進行單純的前後移動的動作，而不產生旋轉動作；然而，當該鼓煞4的來令片(或稱煞車蹄片)磨耗後，對該煞車導線42輸入一煞車拉力P並無法消除該鼓煞4的自由間隙並取得足夠的煞車力，此時使用者(如車輛駕駛人)遂直覺地加強輸入於該煞車導線42的力道，使得該煞車導線42被輸入大於該煞車拉力P的拉力，此時該連接滑座33被拉動的行程會由該導銷341對應的直槽3421範圍過度至斜槽3422，並使該連接滑座33對應地向一第一方向產生轉動，該連接滑座33轉動後即以該單向軸承331帶動該調整螺桿434同步向該第一方向轉動(該單向軸承331向該第一方向轉動時，其內外徑呈鎖止狀態)，使得該調整螺桿434與該套筒螺母435的相對螺鎖作用(該套筒螺母435不動，而該調整螺桿434旋轉而移動)，而以適當的螺距進程縮短該調整螺桿434的作用長度；當使用者移除該大於該煞車拉力P的拉力後，該連接滑座33往回移動，並在該導銷341對應的斜槽3422範圍回到直槽3421範圍時，該連接滑座33對應地向一第一方 向的相反方向產生轉動，該連接滑座33轉動後即以該單向軸承331帶動該調整螺桿434同步向相反於該第一方向轉動(該單向軸承331向該第一方向的反方向轉動時，其內外徑呈釋放狀態而可自由轉動)，因此不會使該調整螺桿434同步產生轉動，也不會再回復之前被調整的作用長度，此時，該煞車搖臂432在未施加煞車拉力時的補償後未煞車初始角度B，因此使該自由間隙被縮小，也因此可使因來令片的磨耗衍生的自由間隙擴大問題獲得補償及修正，如圖7所示。 It is worth mentioning that when the order piece (or the brake shoe piece) of the drumstick 4 is not worn, a pull force P is input to the brake wire 42 to eliminate the free gap of the drumstick 4 and obtain sufficient When the brake force P is removed, the brake rocker arm 432 is pulled back to the original untwisted initial angle A by the restoring force of the pullback spring 433, and the adjustment screw 434, the connection slide 33 and The brake wire 42 is restored to the position before the brake, and the reciprocating stroke of the connecting carriage 33 is moved within a range corresponding to the straight groove 3421 of the guide groove 342 of the fixed guide pin 341, so the connection is slippery. The seat 33 only performs a simple forward and backward movement without generating a rotation motion; however, when the buckle of the drum 4 is worn, a brake force P is input to the brake wire 42 and The free play of the drumstick 4 cannot be eliminated and sufficient braking force is obtained. At this time, the user (such as the driver of the vehicle) intuitively strengthens the force input to the brake wire 42 so that the brake wire 42 is input greater than the brake force. Pulling force of P, at this time the connection is slippery The stroke of the pulled pin 33 is excessively extended by the straight slot 3421 corresponding to the guide pin 341 to the chute 3422, and the connecting slider 33 is correspondingly rotated in a first direction, and the connecting slider 33 is rotated. The one-way bearing 331 drives the adjusting screw 434 to rotate in the first direction synchronously (the one-way bearing 331 is locked in the first direction, the inner and outer diameters thereof are locked), so that the adjusting screw 434 and the sleeve nut 435 Relative screwing action (the sleeve nut 435 is not moving, and the adjusting screw 434 is rotated to move), and the working length of the adjusting screw 434 is shortened by a suitable pitch process; when the user removes the pulling force P greater than the braking force After the pulling force, the connecting sliding seat 33 moves back, and when the corresponding inclined slot 3422 of the guiding pin 341 returns to the range of the straight slot 3421, the connecting sliding seat 33 correspondingly faces a first square. Rotation occurs in the opposite direction, and the connecting carriage 33 rotates to rotate the adjusting screw 434 synchronously opposite to the first direction by the one-way bearing 331 (the one-way bearing 331 rotates in the opposite direction of the first direction) When the inner and outer diameters are in a released state and are free to rotate, the adjusting screw 434 is not rotated synchronously, and the previously adjusted working length is not restored. At this time, the braking arm 432 is not applied. The initial angle B is not braked after the compensation at the time of pulling force, so that the free gap is reduced, and thus the problem of the free gap expansion derived from the wear of the sheet can be compensated and corrected, as shown in FIG.

當然，當該連接滑座33朝向該煞車導線42方向移動並同向地拉動該調整螺桿434時，該調整螺桿434則會因為受限於該煞車搖臂432之偏擺端部4321的向輪內(即朝向該煞車導線42的方向)偏轉，而同時被提高其水平位置，且因連接該調整螺桿434另一端的連接滑座33之外部導引移動之外殼32，係與固定不動的該固定座31樞接，而使該外殼32係與固定座31形成可互相彎折的結構，因此該外殼32及其在內部移動的連接滑座33、該調整螺桿434等構件遂可自動地形成一斜角，而能適應因為該煞車搖臂432偏擺面產生的擺幅。 Of course, when the connecting slider 33 moves toward the braking wire 42 and pulls the adjusting screw 434 in the same direction, the adjusting screw 434 is limited to the turning wheel of the yaw end portion 4321 of the braking rocker arm 432. The inner portion (ie, the direction toward the brake wire 42) is deflected while being horizontally raised, and the outer casing 32 that is moved by the outer portion of the connecting slide 33 connected to the other end of the adjusting screw 434 is fixed and fixed. The fixing base 31 is pivotally connected, so that the outer casing 32 and the fixing base 31 form a structure that can be bent with each other, so that the outer casing 32 and its connecting sliding seat 33, the adjusting screw 434 and the like which are moved inside can be automatically formed. An oblique angle can accommodate the swing caused by the yaw surface of the brake rocker arm 432.
