With a combination of solid and effective effects. [Prior Art] The structure of the wheel hub of the bicycle is used to provide the positioning of the axle and the smooth rotation of the rim. The main fine flower hub, shaft, secret group and paving are composed of the same; It is equipped with a set of touch and shifting devices; if it is differentiated according to the transmission mode, the structure can be divided into "one-way type" and "two-way type", wherein "one-way type" means that the wheel hub can only be rotated in a single direction and can be driven. Usually the direction of the bicycle is forward, and the reverse direction is the idling state of the transmission; the "two-way type" means that both the forward and reverse directions of the hub can be transmitted. Further analysis of the "one-way" drive, which uses the ratchet design as the transmission media boundary, using the mechanical characteristics of the ratchet, the rotary drive, and the other to the idling, so that the bicycle does not step on even when riding. The wheel can still smoothly rotate forward. Such a "unidirectional" wheel with a ratchet structure has a ratcheting drive that can be divided into "radial clamping" and "axial" due to different clamping directions. "Cartridge", wherein "radial clamping" means that the ratchet is extended in the diameter direction of the hub seat and is matched with the radially-clamped ratchet block; the "axially-clamped" ratchet is toward the hub The axially extending convex teeth of the seat are coupled to the ratchet seat with its axial clamping. According to the conventional design, the "radial card" bicycle wheel ratchet structure, such as domestic M415825

The purpose of small, inelastic fatigue. [New content], this is a series of two-step research on the "one-way" and "axial clamping" combination. In the latter structure, the ratchet block 12 is set in the set. In the core 11, and the two records are mutually clamped, the ratchet block is linearly displaced in the axial direction therein; however, the outer diameter of each of the ratchet blocks and the inner diameter of the collar are both decoupled from the axis. _ Mutual, in the process of Yu Narui's miscellaneous action, because of the large contact area and the inability to create gaps, it is easy to cause wear. In addition, the excessive frictional force also makes the ratchet block move linearly, which affects the spine. The complex (four) combined action of the tooth block also makes the hearing of the structure less sensitive. Therefore, the creator of the present case is based on the above-mentioned fact that the axial ratchet structure has a slow returning speed, poor sensitivity, and affects the ratcheting conduction efficiency, and at the same time has a high wear problem, and proposes an innovative bicycle wheel that can solve the aforementioned problems.

Less; frictional force is generated, which improves the quick return of the driven seat, and further improves the sensitivity of the wheel set, so the overall structure can be convenient and practical. (Compared with the efficacy of the prior art) The main goal of this creation is to provide a ratchet structure of a bicycle wheel valley, which utilizes the linear movement of the thief moving seat from the secret domain to the slanting surface. That is, it can generate _ with the inner hole of the inclined cone to achieve the effect of low wear.

A gap d is immediately formed between each of the tapered inner hole (33) and the tapered surface (52), and the two are not in contact with each other. 'And the more the displacement of the driven seat (51), the larger the gap d. In this creation, each of the driven seat (51) and the stop ring (30) is sleeved with each other by a sloped surface, that is, the outer diameter of the driven seat (51) is provided with the tapered surface (52) and the retaining ring is matched ( 30) The inner diameter of the tapered inner bore (33) is matched with the tapered surface (52). The linear design of the driven seat (51) is slightly separated from the coupled state. The hole (33) generates the gap d, so that the entire tooth removing operation is in a state of zero friction force for the tapered surface (52); on the other hand, the driven seat (51) is returned to the linear motion until each of the Before the first and second ratchets (421) (541) are coupled, the tapered surface (52) and the tapered inner bore (33) are both in a zero frictional state with a gap; overall, Although the two sides of the first transmission tooth (35) of the driven seat (51) must have a frictional force as a rotary transmission, the tooth surface portion of the first transmission tooth (35) has been excluded (ie, The frictional force of the tapered surface 52) of the outer diameter of the driven seat. The driven seat (51) is a technical feature of linear displacement in the retaining ring (3〇) in a low friction state, so that the driven seat (51) can be reduced due to frictional resistance. The de-toothing and twisting action is faster, so that the sensitivity of the ratcheting operation can be improved, and the problem that the conventional structure has a slow returning speed, a poor sensitivity, and a low ratcheting efficiency due to the large frictional force is solved. Each of the retaining edge (34) and the blocking portion (53) of the present invention is designed such that the driven seat (51) is pushed by the magnetic set (6〇) and linearly displaced toward the driving base (41) 10 M415825 In this case, the movement of the driven seat (51) can be appropriately performed, and the limit effect is provided; since the mutual repulsion force of the magnetic group (60) cannot be properly controlled, it is feared that the driven seat
(51)位移動作過度而對該驅動座（41)產生衝擊，以致該第二棘 嵩（541)衝撞該第一棘齒(421)而產生損耗；故本創作利用各該 檔緣（34)及擋部（53)之設計可有效擋止該從動座（51)過度位 移而衝撞該驅動座（41)之情形；同時可使該從動座（51)復歸移 動至較精準之位置，以讓各該第一、第二棘齒（421)(541)兩者 間作最佳地嚅合狀態，達到精度佳之效果。 綜合上述，本創作所揭露「自行車輪轂之棘輪結構」，係 提供一具低磨耗、增進復歸速度、可提升靈敏度、及具限位功 能之棘輪結構，制崎面套設之各魏驗及擋止環，使該 從動鋪徽離娜驗’ g卩驗各_φ及斜制孔產生間 隙’同時利用各該擋緣及檔部之設計，可防止該從動座之復歸 動作產生絲娜動賴飾，轉致—翻齡及組裝便利(51) the displacement action is excessive and the drive seat (41) is impacted, so that the second ratchet (541) collides with the first ratchet (421) to cause loss; therefore, the creation utilizes each of the flanges (34) And the design of the blocking portion (53) can effectively block the situation that the driven seat (51) is excessively displaced to collide with the driving seat (41); at the same time, the driven seat (51) can be moved back to a more precise position. In order to optimally knead the first and second ratchets (421) (541), the precision is achieved. In summary, the author discloses the "ratchet structure of bicycle wheel hub", which provides a ratchet structure with low wear, improved return speed, enhanced sensitivity, and limit function. Stop the ring, so that the follow-up shop is separated from the test, and the gap between the _φ and the oblique hole is generated. At the same time, the design of the retaining edge and the gear is used to prevent the return movement of the driven seat from being produced.
