Description of creation (1) [Technical field to which the new type belongs] * η: It is related to :: the ratchet sleeve of the car, especially-a kind of ratchet ring design which can avoid the noise Producer. [Prior art] θ ^ ^ Please refer to [Figures], 2, and 3 as shown in Figure J. It is generally available on the market :; spine = tube i approximately f-circular tube, where the strip is desired, and the set The outer wall of the inner side of the tube i is annularly distributed with the number 2, and the sleeve 2 is outside; = Two extensions: 20%-The annular end of the sleeve tooth 3 is arc-shaped, and Bu = 2 ratchet teeth 3 Ratcheting, wedge-shaped on the outside '; :: § 海!;: = Shape chamber 4 and a spiral ratchet 3 connected to the outer ring bundle of the sleeve 3, which collectively protrudes outwardly to the sleeve g Bing 'enables the moving end of each ratchet 3 to be mounted on a constant shaft sleeve, and its outer side is a ring-shaped ratchet ring 7 which is sleeved on the inner peripheral wall with a ring-shaped distribution thread to lock the hub of the bicycle On the other hand, it corresponds to each ratchet tooth 3 and missing tooth 8. The shape of each missing tooth 8 can use the ratchet tooth 3 fish flower gas 2 J 二 to positively drive the sleeve 1 to rotate, it should be the hub rotation; = f ratchet ring 7 is missing teeth 8 meshing, when the ratchet teeth 3 of the wall are driven and the XI μ shaft is rotated in the reverse direction, the outer ring 7 of the sleeve 1 is idling without the missing teeth 8 of the ring 7 , So that the foot can be swiveled when the pedalling is on, It is when I ride. When the rattles on the outer periphery of the sleeve 1 each go 2 rounds, it is idling when the pedal is reversed; but the buckle 6 will be facing outwards, and the c-shaped teeth will be pressed by the inner peripheral wall of the ratchet ring 7. Zhang, the outer ring wall will make M246115 with the inner wall surface of the ratchet ring 7. Fourth, the creation instructions (2) friction and noise. [New content] This creative self-driving hub sleeve contains a sleeve body and a ratchet ring. The sleeve body is provided with a bushing on the inner side, and a plurality of ratchet teeth are provided on the outer periphery of the sleeve body. The ring is set so that the inner end of the ratchet teeth is a pivot end, and the other side can be opened outward to mesh with the teeth of the ratchet ring to drive the ratchet ring to rotate, and the ratchet teeth can be contracted inward when they are rotated in the opposite direction. To make the ratchet ring idle, this creation is based on the position of the ratchet ring relative to the elastic body ring of the sleeve body, to avoid the friction between the elastic ring and the ratchet ring # 1.喿 Sound production implementation] To make a deeper layer, please refer to [the center is connected to the hub of the bicycle, the sleeve, the peripheral wall of the side is a ring sleeve 12, the slot 1 3, and] the respective accommodation One end of the slot is round, features and effects of the preferred embodiment and cooperates with a bicycle ratchet sleeve to move and rotate, and the system includes: a substantially cylindrical shape, and a circular shape extending outside. Digging inward is provided with three capacity reference practices [Figure 3, Figure 15. The ratchet teeth 1 5 containing grooves 1 3 shape valuable review committee members' understanding and recognition of the purpose of this creation, enumerate one =, Figure 5] , This creation = rod a can be driven by the shaft a to drive the hub b to rotate the sleeve body for 5 weeks ii !: F peripheral wall radial average 1 〇 gen slot 1 4; can be jealous ^, total Insert a ratchet arc to open ... turn ends, and cooperate with the M246115
四、創作說明（3) 以樞接旋轉，使棘齒1 5之另一端為作動端1 5 i ，爷作 動端1 5 1係為楔齒形，並使該作動端1 5丄朝外張& 凸伸於該軸套1 2外徑，縮合時能容設於該容置槽丄3犯 内，而該各棘齒1 5外側設一槽縫1 6。 一彈性束環1 7 (如c型扣環）係組接於該套筒本體 1 0軸套1 2之限位槽1 4内，及圈束於該各棘齒i 5之 槽縫1 6上，以共同將三個棘齒^ 5束接於該轴套^ 2之 谷置槽1 3内，並恆保該三個棘齒1 5之作動端1 5 ;[朝 外張而凸伸出該軸套1 2外徑。 一棘輪環2 0係套接於該套筒本體1 〇上，其内周壁 乃對應該軸套1 2各棘齒1 5分設有複數相對形狀凹向之 卡齒2 1 ’使該套筒本體1 〇能與該棘輪環2 〇嵌合，又 泫棘輪環2 0内周壁環形凹設一迴避空間2 2，該迴避空 間2 2係對應該套筒本體1 〇軸套1 2之彈性束環7位 置。 藉由上述之結構，當該軸桿a正向帶動套筒本體1 〇 迴轉時’套筒本體1 〇上三個棘齒1 5之作動端1 5 1恰 能嵌進於該棘輪環2 〇之卡齒2 1内帶動該棘輪環2 〇 — 起旋轉，進而使自行車花鼓b被帶動產生迴轉。 而當腳反踩自行車踏板時，該軸桿a係反向帶動該套 筒本體1 0旋轉，此時該套筒本體1 〇之三個棘齒1 5可 被棘輪環2 0内周壁壓制，令棘齒1 5作動端1 5 1朝向 縮進於軸套1 2之容置槽1 3内，如此該棘輪環2 〇係為 空轉不能帶動自行車花鼓b旋轉，且該彈性束環1 7會被Fourth, the creation description (3) with the pivot rotation, so that the other end of the ratchet tooth 15 is the actuating end 1 5 i, the master actuating end 1 5 1 is wedge-shaped, and the actuating end 15 is opened outward & It protrudes from the outer diameter of the shaft sleeve 12 and can be accommodated in the accommodation slot 3 when contracted, and a slot 16 is provided on the outer side of each ratchet tooth 15. An elastic binding ring 17 (such as a c-shaped retaining ring) is assembled in the limiting groove 14 of the sleeve body 10, the sleeve 12 and the groove 16 of the ratchet teeth i5. In order to connect the three ratchet teeth ^ 5 bundles to the grooves 1 3 of the sleeve ^ 2 together, and keep the moving ends 15 of the three ratchet teeth 15; Take out the outer diameter of the sleeve 1 2. A ratchet ring 20 is sleeved on the sleeve body 10, and its inner peripheral wall is corresponding to the shaft sleeve 12 and each ratchet tooth 15 points are provided with a plurality of opposite shape concave teeth 2 1 'to make the sleeve The main body 1 can be fitted with the ratchet ring 20, and the inner peripheral wall of the ratchet ring 20 is recessed with an avoidance space 22, which is an elastic bundle corresponding to the sleeve body 10 and the shaft sleeve 12. Ring 7 position. With the above-mentioned structure, when the shaft a is positively driving the sleeve body 1 〇 to rotate, the operating end 1 3 1 of the three ratchet teeth 15 on the sleeve body 10 can fit into the ratchet ring 2. The ratchet ring 20 is driven inside the clamping tooth 21 to rotate, and the bicycle hub b is driven to rotate. When the bicycle pedal is reversed, the shaft a drives the sleeve body 10 to rotate in the reverse direction. At this time, the three ratchet teeth 15 of the sleeve body 10 can be suppressed by the inner peripheral wall of the ratchet ring 20, Make the ratchet 15 actuating end 1 5 1 retract toward the receiving groove 1 3 of the shaft sleeve 12 so that the ratchet ring 2 is idling and cannot drive the bicycle hub b to rotate, and the elastic ring 17 will Be
