In order to drive the brake device by running backward, it is necessary to apply a fixing force to the hub axle via a friction spring, which is usually formed by a coiled spring. However, in order to minimize the loss caused by the friction spring in the starting direction, a flywheel must be introduced between the retainer and the friction spring (which is provided with a hook to become a coiled spring). The flywheel is composed of a first fastening element. And the second fastening element, in which the first fastening element having the shift lever is non-rotatably arranged on the retaining ring by the retaining ring arm. On the other hand, the second fastening element is non-rotatably rubbing against the retaining element. The hooks of the springs are connected. These fastening elements form a flywheel in the starting rotation direction by the pressure of a spring, which uses the teeth in the second fastening element and the fastening window of 200533552 in the first fastening element to respond to the starting rotation direction. Form a positioning effect. The advantage of such a friction device is a nearly complete degree of frictional freedom in the direction of starting rotation, which can result in an improvement in efficiency for the user of the bicycle.
建議藉由第二空心輪來控制上述之倒輪式煞車裝置以作 爲該經由終端滾輪來操控之昂貴的倒輪式煞車裝置下一步 之發展形式,該空心輪圍繞整個傳動器且可引導該倒輪式 煞車裝置使與起動器相連接。此種連接所需的基礎是一種 多擋式輪轂,其具有一種終端側之爪載體和一種從動側的 爪載體,這些爪載體可經由三個行星齒輪而互相連接,其 中藉由一種適當的爪控制器而產生多個傳動比。 第二空心輪在輪轂筒內部中由起動器延伸至倒輪式煞車 裝置中的導引環且因此對煞車動量提供一種由起動器至輪 轂筒之直接傳送路徑。第二空心輪經由至少一個第一煞車 爪和至少一個起動爪而與起動器相連接。自行車騎士向後 踩踏板使該煞車動量經由一種傳動比大約是1: 3之鏈條而 導入至起動器中,該煞車動量然後經由第一煞車爪而導入 至第二空心輪之內齒中且經由至少一個第二煞車爪繼續傳 送至從動側的爪載體,其具有一種包含爬升場(field)之軸 環,軸環上配置著終端滾輪,各終端滾輪互相藉由導引環 而限定在其間距中且在煞車過程中藉由其相對於軸環的旋 轉而在該爬升場上滾動以及佔有徑向中更外側的位置,在 該位置中各終端滾輪使煞車罩叉開,於是在煞車罩和輪轂 筒中的煞車筒之間會形成一種摩擦作用而成爲一種對煞車 動量的反作用,該摩擦作用依據所導入的煞車動量以或多 200533552 或少地對該輪轂筒進行煞車,其中煞車筒是與輪轂筒相連 接而不能旋轉。該導引環顯示一種對該煞車罩的摩擦作 用,煞車罩經由一種錐形桿而與輪轂軸不可旋轉地相連 接,其中導引環在該軸環向後旋轉時落在後面且終端滾輪 可上升至該爬升場。It is suggested that the above-mentioned reverse wheel brake device be controlled by a second hollow wheel as the next development form of the expensive reverse wheel brake device controlled by the terminal roller. The hollow wheel surrounds the entire transmission and can guide the reverse brake. The wheel brake is connected to the starter. The basis required for this connection is a multi-speed hub with a terminal-side claw carrier and a driven-side claw carrier, which can be connected to each other via three planetary gears, with an appropriate The claw controller generates multiple gear ratios. The second hollow wheel extends in the interior of the hub cylinder from the starter to the guide ring in the reverse wheel brake and thus provides a direct transmission path for the brake momentum from the starter to the hub cylinder. The second hollow wheel is connected to the starter via at least one first brake pawl and at least one starting pawl. The bicyclist depresses the pedal backwards to cause the braking momentum to be introduced into the starter via a chain having a transmission ratio of approximately 1: 3, and the braking momentum is then introduced into the inner teeth of the second hollow wheel via the first brake pawl and via at least A second brake claw continues to be transmitted to the driven side of the claw carrier, which has a collar including a climbing field. The collar is provided with end rollers, and each end roller is limited to a distance from each other by a guide ring. During and during the braking process, it rolls on the climbing field and occupies a more radial position in the radial direction by its rotation relative to the collar. In this position, each end roller makes the brake cover split, so the brake cover and A friction effect will be formed between the brake cylinders in the wheel hub cylinder, which will become a reaction to the braking momentum. The friction effect will brake the wheel cylinder more or less 200533552 according to the introduced braking momentum. The brake cylinder is connected with the wheel hub. The barrels are connected and cannot be rotated. The guide ring shows a frictional effect on the brake hood, which is non-rotatably connected to the hub shaft via a tapered rod, where the guide ring falls behind and the terminal roller can rise when the collar rotates backward To the climbing field.
第一煞車爪之控制是各別地以下述方式來進行:終端側的 爪載體經由旋轉間隙而與起動器相連接,當自行車騎士針 對起動旋轉方向而操控該踏板以導入該煞車過程時,該煞 車過程會經由該旋轉間隙而進行。在此種情況下終端側的 爪載體保持靜止直至該旋轉間隙被經過爲止。 一種控制筒不可旋轉地與終端側的爪載體相連接,這表 示:該控制筒相對於向後旋轉的起動器而言一起與終端側 的爪載體保持著落後一段旋轉間隙的距離。起動器在其外 直徑側具有一組起動爪,其持續地與第二空心輪中的齒相 接合著。此外,第一煞車爪配置在相同的外直徑上且對準 該起動旋轉方向以及在運行操作期間必須保持著未接合狀 態。該控制筒上至少一鎧形物(其各別地穿過多組爪之間的 間隙)在起動時覆蓋第一煞車爪且因此可防止各煞車爪接合 至第二空心輪的齒中。若起動器在導入該煞車過程時對著 該終端側的爪載體和該控制筒而在該旋轉間隙之距離處朝 向該起動旋轉方向作旋轉,則該控制筒的鎧形物保持在其 位置中且第一煞車爪在該鎧形物下方向外移動並接合至第 二空心輪之齒中且與向後旋轉的起動器相耦合。各起動爪 因此保持在接合狀態中,但在起動器向後旋轉時會被起動 200533552 器駛過。 該起動器較佳是具有二個相面對的間隙,控制筒上二個鏺 形物經由間隙而延伸,以便對起動器上由於力的平衡而互 相面對的多個第一煞車爪進行控制。The control of the first brake pawl is performed separately in the following manner: the claw carrier on the terminal side is connected to the starter via a rotation gap, and when the cyclist controls the pedal for the starting rotation direction to introduce the braking process, the The braking process takes place via this rotation gap. In this case, the claw carrier on the terminal side remains stationary until the rotation gap is passed. A control cylinder is non-rotatably connected to the claw carrier on the terminal side, which means that the control cylinder is kept behind the claw carrier on the terminal side by a rotation gap relative to the starter rotating backward. The starter has a set of starting claws on its outer diameter side, which are continuously engaged with the teeth in the second hollow wheel. In addition, the first brake pawls are arranged on the same outer diameter and aligned with the starting rotation direction and must remain unengaged during the running operation. At least one armor on the control cylinder, which passes through the gaps between the plurality of sets of claws individually, covers the first brake pawl during starting and therefore prevents each brake claw from engaging into the teeth of the second hollow wheel. If the starter faces the claw carrier on the terminal side and the control cylinder during the braking process, and rotates toward the starting rotation direction at a distance of the rotation gap, the armor of the control cylinder remains in its position. And the first brake pawl moves outward under the armor and engages with the teeth of the second hollow wheel and is coupled with the starter rotating backward. The starting claws are therefore kept in the engaged state, but will be started when the starter rotates backwards. The starter preferably has two facing gaps, and two cymbals on the control cylinder extend through the gaps so as to control the plurality of first brake paws on the starter that face each other due to the balance of forces. .
第二煞車爪之控制是各別地以下述方式來進行··從動側的 爪載體具有三個起動爪,即,至少一個第一起動爪,其使 第二空心輪和從動側的爪載體相連接;至少一個第二起動 爪,其使第一空心輪和從動側的爪載體相連接;以及至少 一個第三起動爪,其使太陽齒輪載體和從動側的爪載體相 連接。第二煞車爪在第一起動爪之周圍區域中在嚙合狀態 下配置在第二空心輪上且可使已導入的對準起動旋轉方向 的煞車動量繼續傳送至從動側的爪載體,該爪載體上配置 著具有爬升場的軸環。但爲了驅動多個第二煞車爪(其較佳 是在從動側的爪載體周圍互相面對而配置著),則配置在從 動側之爪載體上之起動用的全部的起動爪必須處於未接合 之狀態。一種視窗筒配置在各齒和各起動爪之間且藉由摩 擦而與第二空心輪相連接,該視窗筒用來驅動第二煞車 爪。若導入一種煞車過程,則第二空心輪藉由摩擦而使視 窗筒旋轉且全部之起動爪都由視窗筒所覆蓋且處於未接合 狀態中。一種視窗經由目前起動位置中由視窗筒所覆蓋的 第二煞車爪而移動至視窗筒中,第二煞車爪因此可與第二 空心輪相嚙合且使從動側的爪載體向後起動。 在上述的爬升場上配置著多個終端滾輪,其藉由一種導引 環而以習知方式互相保持一段距離。各爬升場在軸環周圍 200533552 須成傾斜狀,使得該從動側的爪載體對著起動旋轉方向而 旋轉時,藉由該導引環而固定在其位置中的各終端滾輪可 在徑向中向外移動。終端滾輪使煞車罩叉開,該煞車罩經 由一種錐形桿而不可旋轉地與自行車的框架相連接且使一 種在運行操作中旋轉的煞車筒停止。該煞車筒不可旋轉地The control of the second brake pawl is carried out individually in the following manner ... The driven claw carrier has three starting claws, that is, at least one first starting claw, which makes the second hollow wheel and the driven side claws The carrier is connected; at least one second starting claw that connects the first hollow wheel and the driven side claw carrier; and at least one third starting claw that connects the sun gear carrier and the driven side claw carrier. The second brake pawl is arranged on the second hollow wheel in the meshing state in the surrounding area of the first starting pawl, and the introduced braking momentum aligned with the starting rotation direction can be continuously transmitted to the pawl carrier on the driven side. The carrier is provided with a collar having a climbing field. However, in order to drive a plurality of second brake claws (which are preferably arranged to face each other around the driven side claw carrier), all the starting claws for starting arranged on the driven side claw carrier must be at Not engaged. A window cylinder is arranged between each tooth and each starting pawl and is connected to the second hollow wheel by friction. The window cylinder is used to drive the second brake pawl. If a braking process is introduced, the second hollow wheel rotates the window cylinder by friction, and all the starting claws are covered by the window cylinder and in an unengaged state. A window is moved into the window barrel via the second brake pawl covered by the window barrel in the current starting position, so that the second brake claw can be engaged with the second hollow wheel and start the claw carrier on the driven side backward. A plurality of terminal rollers are arranged on the above-mentioned climbing field, and they maintain a distance from each other in a conventional manner by a guide ring. Each climbing field must be inclined around the collar 200533552 so that when the claw carrier on the driven side rotates toward the starting rotation direction, each end roller fixed in its position by the guide ring can be in the radial direction Move outward. The end rollers fork off the brake hood, which is connected to the frame of the bicycle non-rotatably via a tapered rod and stops a brake cylinder that rotates during running operation. The brake drum is non-rotatably
與輪轂筒相連接且因此使煞車作用繼續導引至自行車的後 輪。該導引環藉由一種摩擦作用而與煞車罩相連接,於是 該導引環通常可對該軸環的旋轉移動保持著落後狀態。 建議該視窗筒之一種控制的第二種方式,其中該視窗筒是 經由煞車飛輪和煞車環而由第二空心輪所控制。視窗筒不 可旋轉地與煞車環相連接,因此在煞車過程中由第二空心 輪經由持續地保持在接合狀態中的煞車飛輪使該視窗筒向 後地起動。起動時配置在從動側之爪載體上的起動爪藉由 視窗筒中的視窗而與第二空心輪相接合且亦與第一空心輪 和太陽齒輪載體相接合。各起動爪藉由視窗之停止旋轉而 未接合至視窗筒中且該煞車環可使從動側的爪載體向後起 動。在從動側的爪載體和煞車環之間配置一種具有旋轉間 隙的第二耦合器,該旋轉間隙在視窗停止旋轉時由各起動 爪所駛過,以便在繼續向後旋轉時該倒輪式煞車裝置可以 上述方式被設定成活動狀態。 踏板之操作返回至起動旋轉方向時,一旋轉彈簧或第二空 心輪和視窗筒之間的摩擦會將該視窗筒帶引至起動旋轉方 向中,該視窗於是又經由起動爪而移動且驅動各起動爪。 有利的是使旋轉彈簧配置在間隔環中,該間隔環不可轉地 _ 9 - 200533552 與第二空心輪相連接且可使安裝簡易。 【發明內容】 本發明的目的是藉由一種配置在外部的開關裝置以經由 多個飛輪來控制一種具有多個行星齒輪之多擋式輪轂,這 些行星齒輪可互相耦合以起動-或操控一種倒輪式煞車裝 置。It is connected to the hub cylinder and thus the braking action is continued to the rear wheel of the bicycle. The guide ring is connected to the brake hood by a friction effect, so the guide ring can usually keep the rotation of the collar behind. A second method of controlling the window tube is suggested, wherein the window tube is controlled by a second hollow wheel via a brake flywheel and a brake ring. The window barrel is non-rotatably connected to the brake ring, so the second hollow wheel is used to start the window barrel backwards through the brake flywheel which is continuously maintained in the engaged state during braking. The starting pawl arranged on the driven side pawl carrier at the time of starting is engaged with the second hollow wheel and also with the first hollow wheel and the sun gear carrier through a window in the window cylinder. Each starting pawl is not engaged with the window cylinder by stopping the rotation of the window, and the brake ring can move the claw carrier on the driven side backward. A second coupler with a rotating gap is arranged between the claw carrier on the driven side and the brake ring, and the rotating gap is passed by the starting claws when the window stops rotating, so that the reverse wheel brake is continued when the rotation is continued backward The device can be set to the active state in the manner described above. When the operation of the pedal is returned to the starting rotation direction, the friction between a rotating spring or the second hollow wheel and the window barrel will lead the window barrel belt into the starting rotation direction, and the window will then move through the starting claw and drive each Starting claw. It is advantageous to arrange the rotary spring in a spacer ring, which is non-rotatably connected to the second hollow wheel and allows easy installation. SUMMARY OF THE INVENTION The object of the present invention is to control a multi-speed hub with a plurality of planetary gears through a plurality of flywheels through a switch device arranged externally. The planetary gears can be coupled to each other to start-up or control a reverse Wheel brakes.

To the notch 19, the notch 19 is arranged on the starter 2, and when the starter 2 switches the starting rotation direction 16, the notch enables the starter 2 to form a rotation gap with respect to the control cylinder 13. In addition, the transmission has three planetary gears, that is, a first planetary gear 20, a second planetary gear 21, and a third planetary gear 22, and the claw carrier 7 on the terminal side can be formed by these planetary gears under various transmission ratios. It is compatible with the moving claw carrier 2 3. Therefore, 'brother_►' the hollow wheel 6 can be connected to the driven claw carrier 23 via the lifting claw 24 and the second brake claw 25; a hollow wheel 9 can be connected to the driven claw carrier 23 via the starting claw 26. Then, the sun gear carrier 12 is connected to the claw carrier 23 on the driven side via the starting claw 27. As shown in FIG. 4, the claw carrier 23 on the driven side has a collar 28 having a climbing field 29, and the end rollers 30 can roll on the climbing field. Each end roller 30 must be guided by a guide ring 31. A terminal roll 30 can roll on each climbing field 29. A friction 33 is arranged between the guide ring 31 and a brake cover 32 which is non-rotatably connected to the hub shaft 1. Its function is to guide the claw carrier 23 against the claw carrier 23 when the driven side claw carrier 23 rotates backward. While fixing the end rollers 30, each climbing field moves below the end rollers and is therefore shifted outward in the radial direction, so that the brake cover 3 2 is opened with a brake cylinder 34 that is non-rotatably connected to the hub shaft 3. . According to Fig. 4, each of the starting claws 24, 26, 27 must be released by the window barrel 35 so that a window is shown respectively through the corresponding starting claws 24 '26, and the middle 19 is driven by the first connected body including the rotary member. 31 Final pair fork-11- 27 200533552 and offset. Each starting pawl 24, 26, 27 can now be engaged into a tooth provided therefor. However, the window barrel 35 also covers the second brake pawl 25. When the window barrel 35 rotates toward the starting rotation direction 16 during braking, the second brake pawl 25 can run to form a connection with the teeth of the second hollow wheel 6. The window 36 thus comes above the second brake pawl 25 and comes into contact with the teeth of the second hollow wheel 6, and each of the starting pawls 24, 26, 27 is guided by the window barrel 35 into an unengaged state.
最後,由第5圖可知:就像倒輪式煞車裝置之另一種控制 方式一樣,由第二空心輪6經由煞車飛輪44和煞車環43 來控制該視窗筒3 5。與第二空心輪6相連接的煞車飛輪44 是與煞車環43之內齒在起動旋轉方向16之反方向中一起作 用且使與煞車環43不可旋轉地相連接的視窗筒35向後旋 轉,因此可控制各起動爪24,26,27且從動側的爪載體23 由第二耦合器40以一種旋轉間隙而向後一起攜帶著。形成 在從動側之爪載體23上的軸環28及其爬升場29現在將終 端滾輪30導引至煞車罩32下方的煞車位置中。第二空心輪 6經由一種摩擦件42而與視窗筒35相連接,該摩擦件42 在煞車過程完全結束之後用來使視窗筒35回復原位。該摩 擦件42之任務亦可由一種旋轉彈簧來執行,該旋轉彈簧較 佳是配置在視窗筒3 5和從動側的爪載體2 3之間。 本發明的優點是控制筒13(其包含鎧形物14)以及視窗筒 35之成本有利的配置方式,其中該控制筒13用來在起動期 間控制該起動器2上的煞車爪5,視窗筒35用來控制從動 側的爪載體23上的三個起動爪24,26,27,使煞車過程導 入至一種只受到多個爪所控制的多擋式輪轂中。 -12- 200533552 【圖式簡單說明】 第1圖一種多擋式輪轂之部份切面圖,包括一種起動器, 控制筒,終端側的爪載體,從動側的爪載體以及倒 輪式煞車裝置,其具有一種軸環,導引環和一種位 於煞車罩內部的終端滾輪。 第2圖起動器配置之透視圖,其具有一種間隙和一種配置 在間隙內且位於控制筒上的鎧形物,控制筒用來控Finally, it can be seen from FIG. 5 that, just like another control method of the reverse wheel brake device, the second hollow wheel 6 controls the window barrel 35 through the brake flywheel 44 and the brake ring 43. The brake flywheel 44 connected to the second hollow wheel 6 cooperates with the inner teeth of the brake ring 43 in the reverse direction of the starting rotation direction 16 and rotates the window barrel 35 which is non-rotatably connected to the brake ring 43. Therefore, Each of the starting pawls 24, 26, 27 can be controlled and the pawl carrier 23 on the driven side is carried back together by a second coupling 40 with a kind of rotational gap. The collar 28 and its climbing field 29 formed on the pawl carrier 23 on the driven side now guide the end roller 30 into the braking position under the brake cover 32. The second hollow wheel 6 is connected to the window barrel 35 via a friction member 42 which is used to return the window barrel 35 to its original position after the braking process is completely completed. The task of the friction member 42 can also be performed by a rotary spring, which is preferably disposed between the window barrel 35 and the claw carrier 23 on the driven side. The advantage of the present invention is the cost-effective configuration of the control cylinder 13 (which includes the armor 14) and the window cylinder 35, wherein the control cylinder 13 is used to control the brake pawl 5 and the window cylinder on the starter 2 during starting. 35 is used to control the three starting pawls 24, 26, 27 on the pawl carrier 23 on the driven side, so that the braking process is introduced into a multi-speed wheel hub controlled only by a plurality of pawls. -12- 200533552 [Brief description of the drawings] Fig. 1 is a partial cutaway view of a multi-speed wheel hub, including a starter, a control cylinder, a claw carrier on the terminal side, a claw carrier on the driven side, and a reverse wheel brake device It has a collar, a guide ring and a terminal roller located inside the brake hood.
