Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and more specifically, to a hub assembly structure for side-mounted spokes. Background Technology

[0002] Existing bicycle wheels include a hub, an inner rim, and multiple spokes. The flange of the hub has an opening arranged in the circumferential direction. The structure of this opening is shown in the attached drawing of the specification of the force distribution device for bicycle wheel spokes disclosed in Chinese Patent CN103241060A. Figure 1 The mounting opening is indicated by reference numeral 38. One end of the spoke has a cap, and the other end has a threaded shaft. The central component is flat, and its structure can be referenced from the spoke structure disclosed in Chinese Patent CN107953720A, which describes a spoke for a bicycle wheel and a method for manufacturing the same. The inner rim of the wheel is used to mount the tire, and mounting holes are provided on the inner circumference of the inner rim. During assembly, the threaded end of the spoke is passed through the opening on the hub, so that the cap is limited by the opening, and the threaded shaft connects to the mounting hole. The width of the central component of the spoke directly affects the size of the opening; the wider the spoke, the larger the opening. This also means an increase in the diameter of the hub flange, resulting in a heavier and more expensive hub, which is inconsistent with the current trend of lightweight bicycles. Furthermore, due to the limitation of the opening size, spokes with a width greater than the opening size cannot be inserted, resulting in low wheel compatibility, which will also increase product development and manufacturing costs. Utility Model Content

[0003] This utility model discloses a wheel hub assembly structure for side-mounted spokes, aiming to improve the problems of large weight and low compatibility of existing wheel hub spoke assembly structures.

[0004] The present invention adopts the following solution:

[0005] A hub assembly structure for side-mounted spokes is disclosed for assembling spokes. The spokes have a central component located between a first nozzle and a second nozzle, a cap connected to the first nozzle, and a threaded portion connected to the second nozzle. The radial dimension of the central component is larger than the radial dimension of either nozzle. The hub assembly structure includes a hub body with two flanges spaced apart. Each flange has a plurality of mounting grooves recessed on its outer circumferential surface. Each mounting groove has two limiting sections and a clearance section communicating with both limiting sections, allowing the spoke cap to be inserted into the clearance section along the side of the hub body, and the first nozzle to be embedded and limited within the limiting section.

[0006] As a further improvement, the flange has a plurality of teeth arranged in an array along the circumferential direction, and each tooth has a mounting groove formed thereon.

[0007] As a further improvement, one end of the limiting segment is connected to the yielding segment, and the other end is provided through the tooth.

[0008] As a further improvement, the yielding section is configured to extend axially along the hub body, and two limiting sections are located on both sides of the yielding section.

[0009] As a further improvement, the yielding section is runway-shaped, and the two limiting sections are located on the two straight sides of the yielding section and are staggered.

[0010] As a further improvement, the included angles between the two limiting segments and the yielding segment are the same.

[0011] As a further improvement, the assembly slot is arranged in a Z-shape.

[0012] As a further improvement, one end of the limiting segment connected to the yielding segment is provided with a countersunk hole along the extending direction of the limiting segment. The inner wall surface of the countersunk hole is similar in shape to the outer wall surface of the cap, in order to limit the swing of the cap.

[0013] As a further improvement, the bottom surface of the limiting segment is configured to be inclined upward from the bottom surface of the yielding segment.

[0014] As a further improvement, the two flanges are a first flange and a second flange, the size of the first flange is smaller than the size of the second flange, and the connecting wall between the two flanges is inclined.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. By inserting the spokes into the mounting slot from the side of the hub body, the first nozzle is positioned, enabling side-mounted spoke assembly. This eliminates the need for perforation, thus avoiding the influence of the mounting slot's size on the width of the central spoke component. Assuming the crown and first nozzle are of the same standard size, the mounting slot can accommodate central components of any width, improving its compatibility and reducing development and manufacturing costs. Simultaneously, the flange size is no longer affected by the central component's size, meaning the flange can be made smaller than existing technologies, achieving hub weight reduction and ensuring the overall weight of the bicycle. Furthermore, compared to perforated assembly, side-mounted assembly facilitates spoke installation and removal, saving assembly time and simplifying wheel maintenance and spoke replacement. Additionally, the clearance section connects to the two limiting sections, allowing two spokes to be installed in one mounting slot, resulting in a more compact structure and further reducing the flange size and overall hub weight.

[0017] 2. Setting the flange to a tooth shape can reduce the material weight on the flange and improve the weight reduction effect.

[0018] 3. The allowance section extends axially along the hub body to ensure the installation width, which facilitates the assembly of the spokes and avoids the situation where the nut needs to be perfectly aligned to be inserted due to the narrow width. Attached Figure Description

[0028] Example

[0029] Combination Figures 1 to 7 This embodiment provides a hub assembly structure for side-mounted spokes, used to assemble spokes 1. Spokes 1 have a central component 13 located between a first nozzle 11 and a second nozzle 12, a cap 14 connected to the first nozzle 11, and a threaded portion 15 connected to the second nozzle 12. The radial dimension of the central component 13 is larger than the radial dimension of either nozzle. Specifically, the hub assembly structure includes a hub body 2, on which two flanges are spaced apart. Each flange has a plurality of assembly grooves 23 recessed on its outer circumferential surface. The assembly grooves 23 have two limiting sections 232 and a clearance section 231 connected to both limiting sections 232, so that the cap 14 of the spokes 1 can be inserted into the clearance section 231 along the side of the hub body 2, and the first nozzle 11 is embedded and limited within the limiting section 232.

[0030] It should be noted that in this embodiment, inserting the spoke 1 into the mounting groove 23 from the side of the hub body 2 is sufficient to limit the first nozzle 11, achieving side-mounted mounting of the spoke 1 without the need for perforation. This avoids the size of the mounting groove 23 being affected by the width of the central component 13. Assuming the cap 14 and the first nozzle 11 are of the same standard size, the mounting groove 23 can accommodate central components 13 of any width, improving its compatibility and reducing development and manufacturing costs. Simultaneously, the flange size is no longer affected by the size of the central component 13, meaning the flange size can be made smaller than existing diameters, achieving wheel weight reduction and ensuring the overall weight of the bicycle. Furthermore, compared to perforation mounting, side-mounted mounting facilitates the installation and removal of the spoke 1, saving assembly time and simplifying wheel maintenance and spoke 1 replacement. In addition, the yielding section 231 is connected to the two limiting sections 232, which means that two spokes 1 can be installed in a mounting slot 23 to make the structure more compact, thereby further reducing the size of the flange and reducing the overall weight of the wheel hub.

[0031] In a preferred embodiment, the flange has a plurality of teeth 24 arranged in a circumferential direction, each tooth 24 having a mounting groove 23 formed thereon. The space between two adjacent teeth 24 is recessed, thereby reducing the material weight on the flange and improving the weight reduction effect. Furthermore, a limiting section 232 is connected at one end to a relief section 231, and the other end passes through the teeth 24, so that the end of the spoke 1 with the threaded portion 15 can extend out of the teeth 24 along the limiting section 232 during assembly.

[0032] Based on the above embodiments, in an optional embodiment of this utility model, the clearance section 231 is configured to extend axially along the hub body 2, and two limiting sections 232 are respectively located on both sides of the clearance section 231. The axial extension of the clearance section 231 along the hub body 2 ensures the installation width to facilitate the assembly of the spokes 1. For example, during installation, after the cap 14 partially enters the clearance section 231, it can move along the clearance section 231 into the limiting section 232. The elongated clearance section 231 reduces the clearance space while ensuring the width of the cap 14 to enter the clearance section 231, facilitating the assembly of the spokes 1 and preventing the cap 14 from needing to be perfectly aligned to be inserted due to insufficient width. Preferably, the clearance section 231 is racetrack-shaped, and the two limiting sections 232 are respectively located on the two straight sides of the clearance section 231 and are staggered to prevent interference between the two spokes 1 during assembly. In one embodiment, the included angle between the two limiting segments 232 and the yielding segment 231 is the same to ensure the angle of the two spokes 1. Exemplarily, the assembly groove 23 is arranged in a Z-shape, but it is not limited thereto and is not specifically limited thereto.

[0033] In other embodiments, one end of the limiting section 232 connected to the yielding section 231 is provided with a countersunk hole 2321 extending along the direction of the limiting section 232. The inner wall of the countersunk hole 2321 is similar in shape to the outer wall of the cap 14, which is used to limit the swing of the cap 14. The cap 14 is confined within the countersunk hole 2321, and the threaded portion 15 is connected to the mounting hole on the inner rim of the wheel, so that the spokes 1 can be tensioned, and in this tensioned state, the spokes 1 cannot come out of the mounting groove 23. In another embodiment, the bottom surface of the limiting section 232 is configured to be inclined upward from the bottom surface of the yielding section 231, which is used to control the mounting angle of the spokes 1, ensure the support strength of the spokes 1, and thus ensure the riding performance. At the same time, it can also prevent the spokes 1 from interfering with the adjacent teeth 24.

[0034] Based on the above embodiments, in an optional embodiment of the present invention, the two flanges are a first flange and a second flange, wherein the size of the first flange is smaller than the size of the second flange, and the connecting wall 5 between the two flanges is inclined, which can optimize the weight distribution of the wheel to obtain better performance.

[0035] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
