Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle hubs, and in particular to a bicycle hub with good noise reduction effect. Background Technology
[0002] A bicycle hub is a common bicycle accessory, often used on bicycle wheels. It is a double-layered structure that allows relative rotation. The inner axle connects to the bicycle wheel axle, while the outer hub body connects to the bicycle spokes and the chainring to drive the wheel to rotate.
[0003] In existing bicycle hubs, if the rider stops pedaling during riding, the ratchet mechanism inside the hub is activated, which may cause additional noise during riding. In short, when the pedals are not being pressed, the ratchet structure inside the hub will intervene, which may cause increased noise and disrupt riding comfort.
[0004] To address the aforementioned issues, this application proposes a bicycle hub with excellent noise reduction performance. Utility Model Content
[0005] (I) Purpose of the utility model
[0006] To address the technical problems existing in the background art, this utility model proposes a bicycle hub with good noise reduction effect. When riding, the drive component drives the driven component to rotate to drive the outer shaft, and when pedaling stops, the noise generation is reduced.
[0007] (II) Technical Solution
[0008] To solve the above problems, this utility model provides a bicycle hub with good noise reduction effect, including an inner shaft and an outer shaft disposed on the inner shaft. A driven member is fixedly mounted on the outer shaft, and a driving member is connected to the driven member.
[0009] The driven component includes a conical gear ring, and the driving component includes a conical gear and a one-way rotating shaft connected to the conical gear. The conical gear is driven to rotate by the one-way rotating shaft. When the conical gear stops driving, the conical gear is driven to rotate by the conical gear ring.
[0010] Preferably, the driven member further includes a ring housing, which is fixedly fitted on the outer shaft, and the conical toothed ring is fixedly fitted inside the ring housing.
[0011] Preferably, the driving component further includes an annular shell, which is rotatably connected to the inner shaft. The annular shell is rotatably sleeved on the inner shaft. The bevel gear is connected to the annular shell through a one-way rotating shaft and meshes with a bevel gear ring.
[0012] Preferably, the annular shell is rotatably connected to the inner shaft via a bearing.
[0013] Preferably, a sealing bolt is threaded onto the ring shell, and a magnetic rod is fixedly connected to the insertion end of the sealing bolt.
[0014] Preferably, a flow guide shell is fixedly connected to the rotating part of the unidirectional rotating shaft, and a rotating ring is fixedly connected to the flow guide shell through a connecting pipe. The rotating ring is rotatably connected to a collecting ring shell, which is fixedly connected to the ring shell and slidably sleeved with the magnetic rod.
[0015] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0016] The ring housing and sprocket are fixedly connected. When the sprocket is driven by pedaling force, it drives the ring housing to rotate. At this time, the one-way shaft rotates with the revolution of the ring housing, but it does not rotate relative to the ring housing itself. The one-way shaft is connected to the conical toothed ring and the ring housing through a bevel gear, so the conical toothed ring also rotates. The rotation of the conical toothed ring further drives the rotation of the outer axle and the wheel, realizing the riding action. When the sprocket stops being pedaled, the ring housing and the conical toothed ring will continue to rotate for a period of time. During this process, the conical toothed ring will react on the bevel gear, causing it to rotate. Since the bevel gear rotates around the conical toothed ring, this rotation method reduces the blocking response compared with the existing ratchet structure, thus achieving the effect of noise reduction.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] like Figure 1-4 As shown, the present invention proposes a bicycle hub with good noise reduction effect, including an inner shaft 1 and an outer shaft 2 disposed on the inner shaft 1. A driven member 3 is fixedly mounted on the outer shaft 2. The driven member 3 includes a ring shell 32, which is fixedly mounted on the outer shaft 2. A conical toothed ring 31 is fixedly mounted inside the ring shell 32. The driven member 3 is connected to a driving member 4.
[0024] The driven member 3 includes a bevel gear ring 31, and the driving member 4 includes a bevel gear 41 and a one-way rotating shaft 42 connected to the bevel gear 41. The bevel gear 41 is driven by the one-way rotating shaft 42 to rotate the bevel gear ring 31. When the bevel gear 41 stops driving, the bevel gear 41 is driven by the bevel gear ring 31 to rotate.
[0025] The drive component 4 also includes an annular shell 43, which is rotatably connected to the annular shell 32. The annular shell 43 is rotatably sleeved on the inner shaft 1. The bevel gear 41 is connected to the annular shell 43 through a one-way rotating shaft 42. The bevel gear 41 meshes with the bevel gear ring 31. The annular shell 43 is rotatably sleeved on the inner shaft 1 through a bearing 44.
[0026] The interior of the ring shell 43 and the ring shell 32 contains lubricating oil. Due to the transmission between the gears, wear debris is generated. A sealing bolt 45 is threaded onto the ring shell 43. A magnetic rod 46 is fixedly connected to the insertion end of the sealing bolt 45. When the magnetic rod 46 is inserted, it sucks up and collects the debris inside the lubricating oil, which is convenient for removal and cleaning by disassembling the sealing bolt 45.
[0027] To further enhance the cleaning effect, a guide shell 47 is fixedly connected to the rotating part of the one-way rotating shaft 42. The guide shell 47 is fixedly connected to a rotating ring 49 through a connecting pipe 48. The rotating ring 49 is rotatably connected to a collecting ring shell 410. The collecting ring shell 410 is fixedly connected to the ring shell 43 (a drain hole is provided on the outer periphery of the collecting shell 410 to drain the oil that enters the collecting shell 410). It is also slidably sleeved with the magnetic rod 46. When the user stops stepping on the pedal to drive the ring shell 43 to rotate, the continuous rotation of the ring shell 32 and the conical toothed ring 31 drives the conical gear 41 and the rotating part of the one-way rotating shaft 42 to rotate, so as to guide the lubricating oil in the guide shell 47 to the interior of the collecting ring shell 410.
[0028] In this invention, the ring shell 43 is fixedly fitted with the sprocket. When the sprocket is driven by pedaling, it drives the ring shell 43 to rotate. The one-way rotating shaft 42 revolves around the ring shell 43 without rotating relative to itself. This drives the conical toothed ring 31 and the ring shell 32 to rotate through the conical gear 41. The rotation of the conical toothed ring 31 drives the outer shaft 2 and the wheel to rotate. After the sprocket stops being pedaled, the ring shell 32 and the conical toothed ring 31 continue to rotate. The conical toothed ring 31 acts on the conical gear 41 to rotate, and the conical gear 41 rotates itself, causing the one-way rotating shaft 42 to rotate relative to itself. Since the conical gear 41 rotates around the conical toothed ring 31, it provides a blocking response relative to the existing ratchet structure, thereby reducing noise during riding.
[0029] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
