由DE 19617732A1中已知在自行車輪轂中一種起動裝置 -或倒輪式煞車裝置用的終端滾輪耦合器控制時用的摩擦裝置，其包含：一種起動元件，其具有一爬升面外形（pro file)，至少一滾輪和一種具有護圈臂之護圈環；以及一種從動元件。爲了藉由向後運行來驅動該煞車裝置，則須經由一摩擦彈簧而施加一種固定力至輪轂軸，該固定力通常藉由一種盤繞彈簧來形成。但爲了在起動方向中使摩擦彈簧所產生的損耗最小化，則須在護圈和該摩擦彈簧（其設有一種鉤而成爲盤繞彈簧）之間導入一種飛輪，該飛輪由第一扣接元件和第二扣接元件所形成，其中具有撥桿之第一扣接元件不可旋轉地利用護圈臂而配置在護圈環上·，另一方面，第二扣接元件不可旋轉地與該摩擦彈簧之鉤相連接。這些扣接元件藉由一種彈簧之壓力而在起動旋轉方向中形成一種飛輪，該彈簧藉由第二扣接元件中的齒和第一扣接元件中 200533552 的扣接窗以針對該起動旋轉方向形成一種定位作用。此種摩擦裝置之優點是在起動旋轉方向中一種幾近完全之摩擦自由度，這對自行車使用者而言可造成效率上的改進。Known from DE 19617732 A1 is a friction device for the control of a starter-or end-wheel coupler for a reversing brake in a bicycle wheel hub, comprising: a starting element having a climbing surface profile At least one roller and a retainer ring with a retainer arm; and a driven element. 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.

上述目的之解法分別描述在申請專利範圍獨立項第1項和附屬項第1 5項之特徵中。其它形式可由申請專利範圍各附屬項得知。以下將依據多個圖式來描述一種多擋式輪轂，其具有三個受飛輪控制之行星齒輪和一個倒輪式煞車裝置。【實施方式】依據第1圖，所建議的多擋式輪轂由輪轂軸1，起動器2(作爲起動用）’輪轂筒3(作爲起動用）以及一種位於輪轂筒3 內部中的傳動器所構成。傳動器基本上由起動器2和終端側的爪載體7所構成，起動器2具有起動爪4和煞車爪5, 起動爪4和煞車爪5作用在第二空心輪6上。爪載體7具有第一起動爪8和第二起動爪10，第一起動爪8作用在第一空心輪9之齒上且第二起動爪10作用在撥桿筒11之齒上，撥桿筒11不可旋轉地與太陽齒輪載體12相連接。如第2圖所示，起動器2內部中配置一種控制筒13,其具有一種在徑向中向外指之鎧形物1 4，該鎧形物1 4穿過該起動器2中的間隙1 5且對準一種起動旋轉方向1 6以及在起動情況下使煞車爪5處於未接合狀態中。 -10-The solution of the above purpose is described in the features of independent item 1 and subordinate item 15 of the scope of patent application. Other forms can be learned from each subsidiary of the scope of patent application. A multi-speed wheel hub with three planetary gears controlled by a flywheel and a reverse wheel brake device will be described below based on multiple drawings. [Embodiment] According to FIG. 1, the proposed multi-speed hub is composed of a hub shaft 1, a starter 2 (for starting), a hub cylinder 3 (for starting), and a transmission mechanism located inside the hub cylinder 3. Make up. The actuator is basically composed of a starter 2 and a claw carrier 7 on the terminal side. The starter 2 has a starting claw 4 and a brake claw 5, and the starting claw 4 and the brake claw 5 act on the second hollow wheel 6. The claw carrier 7 has a first starting claw 8 and a second starting claw 10. The first starting claw 8 acts on the teeth of the first hollow wheel 9 and the second starting claw 10 acts on the teeth of the lever cylinder 11. The lever cylinder 11 is non-rotatably connected to the sun gear carrier 12. As shown in FIG. 2, a control cylinder 13 is arranged inside the starter 2, which has a armor 14 pointing outward in the radial direction, and the armor 14 passes through the gap in the starter 2. 15 is aligned with a starting rotation direction 16 and the brake pawl 5 is in the disengaged state during starting. -10-

200533552 鏖 » 由第3圖可知，該控制筒13具有一種撥桿17，其藉由種螺栓1 8使該控制筒1 3與終端側的爪載體7相連接，其該螺栓18以其終端接合至凹口 19中，凹口 19配置在起器2上，且當起動器2使起動旋轉方向16切換時該凹口使起動器2可相對於該控制筒1 3來形成一種旋轉間隙。此外，傳動器具有三個行星齒輪，即，第一行星齒輪20 第二行星齒輪2 1和第三行星齒輪22，終端側的爪載體7 由這些行星齒輪在形成各種不同的傳動比之情況下可與動側的爪載體2 3相親合。因此’弟_►空心輪6可經由起爪24和第二煞車爪25而與從動側的爪載體23相連接；一空心輪9可經由起動爪26而與從動側的爪載體23相接，且太陽齒輪載體12經由起動爪27而與從動側的爪載 23相連接。如第4圖所示，從動側的爪載體23具有一種有爬升場29之軸環28，終端滾輪30可在爬升場上滾動各終端滾輪30須由一種導引環31所導引’使一終端滾 30可在每一爬升場29上滾動。在導引環31和一種不可轉地與輪轂軸1相連接的煞車罩32之間配置一種摩擦 33，其作用是在從動側的爪載體23向後旋轉時導引環可針對該爪載體23而使終端滾輪30固定’各爬升場則在端滾輪下方移動且因此在徑向中向外偏移’使煞車罩3 2 著一種不可旋轉地與輪轂軸3相連接的煞車筒34而被開。依據第4圖，各起動爪24，26，27須由視窗筒35釋放使如圖所示分別有一視窗經由相對應的起動爪24 ’ 26，中動 19 藉從動第連體含輪旋件 31 終對叉 -11- 27 200533552 而偏移。各起動爪24，26，27目前可接合至爲其所設的齒中。但視窗筒35亦覆蓋第二煞車爪25，當該視窗筒35在煞車過程中向著起動旋轉方向16而旋轉時該第二煞車爪25 可運行至與第二空心輪6之齒形成連接。視窗36因此來到第二煞車爪25之上方且與第二空心輪6之齒形成接觸，各起動爪24，26，27則由視窗筒35導引成未接合狀態。200533552 鏖 »As can be seen from Fig. 3, the control cylinder 13 has a lever 17 which connects the control cylinder 13 to the terminal claw carrier 7 by means of a bolt 18, and the bolt 18 is engaged at its terminal. 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.
