Description

Technical Field

[0001] This utility model relates to the field of wheel technology, and in particular to a spoke assembly and a wheel. Background Technology

[0002] Cycling is a popular aerobic exercise. It uses bicycles as a means of transportation, with participants moving forward by pedaling. Cycling can be done on city roads, country trails, or dedicated tracks, providing exercise, improving cardiovascular function, and allowing participants to enjoy the scenery. It is also environmentally friendly and convenient, making it popular among people of all ages.

[0003] Bicycle wheels must bear the weight of the user and the frame during riding, and withstand the vertical impacts and lateral swaying stresses from complex road conditions. Currently, common wheel spoke weaving techniques include divergent weaving and cross-weaving. Divergent weaving suffers from low force transmission efficiency; while cross-weaving can transmit force, when external factors cause a significant decrease in spoke tension, spoke misalignment and detachment are very likely to occur, seriously affecting the stability of the wheel structure.

[0004] To address the aforementioned issues, utility model patent CN218054731U discloses a spoke assembly with a buckle and a wheel. The spoke assembly of the bicycle wheel is equipped with a buckle, which holds the intersecting spokes in the buckle's groove, thereby making the connection between the spoke assembly and the hub and rim more secure.

[0005] However, in the above technical solutions, the buckle may fall off due to severe bumps during riding, and the buckle cannot perfectly adapt to the gaps between different spokes, which may bring additional stress after the buckle is installed. Summary of the Invention

[0006] The purpose of this invention is to provide a spoke assembly and wheel to solve the problem that the buckle may fall off due to bumps.

[0007] To achieve the above objectives, this utility model discloses a spoke assembly, comprising: spokes and carbon fiber rings; the spokes 310 are made of carbon fiber material, and each spoke includes a curved segment and two straight segments, the two straight segments being fixedly connected to the two ends of the curved segment, the curved segment being disposed in the middle of the spoke assembly. The spokes are arranged in an interlaced manner, and the carbon fiber rings are disposed at the intersection of the two spokes and located at both ends of the curved segment, the carbon fiber rings being made by curing carbon fiber wound around the surface of the spokes.

[0008] Preferably, the included angle between the two line segments is in the range of 100°-170°.

[0009] Preferably, the curved segments of multiple spokes overlap sequentially to form a circular inner contour. The two ends of the curved segment of each spoke are the first and second intersecting points, respectively. The two sides of each spoke are the first adjacent spoke and the second adjacent spoke, respectively. The first intersecting point of each spoke is stacked on the outside of the first adjacent spoke, and the second intersecting point is stacked on the inside of the second adjacent spoke. Both the first and second intersecting points are provided with carbon fiber rings.

[0010] Preferably, the spoke assembly has six spokes.

[0011] A wheel includes a hub, a rim, and a spoke assembly. The hub includes a hub body and a flange, the flange being detachably mounted on the hub body and used for mounting the spoke assembly. The spoke assembly is fixedly mounted on the rim on the side of the hub away from the hub.

[0012] Preferably, the flange includes a first flange and a second flange, and the spoke assembly is disposed between the first flange and the second flange. The first flange is provided with a first receiving groove for installing spokes and a second receiving groove for installing carbon fiber rings. The second flange is provided with a third receiving groove for installing spokes and a fourth receiving groove for installing carbon fiber rings.

[0013] Preferably, the first flange and the second flange are fixedly connected by adhesive.

[0014] Preferably, the spoke assembly, flange, and rim are all made of carbon fiber.

[0015] This utility model has the following beneficial effects:

[0016] 1. The carbon fiber ring of this utility model is closely attached to the surface of the spokes, which can stabilize and fix the intersecting spokes while also preventing the carbon fiber ring from falling off due to vibration.

[0018] 3. The carbon fiber ring of this utility model is set at the position where two adjacent spokes intersect, which can effectively constrain the relative movement of the spokes and enhance the structural stability of the entire spoke assembly.

[0019] 4. The carbon fiber ring of this utility model is completely embedded inside the two flange receiving grooves, thereby increasing the firmness of the carbon fiber ring installation. Attached Figure Description

[0030] 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 the accompanying drawings and embodiments.

[0031] like Figures 1-8 This utility model provides a spoke assembly, including: spokes 310 and a carbon fiber ring 320. The spokes 310 are made of carbon fiber material and include a curved segment 312 and two straight segments 311. The two straight segments 311 are fixedly connected to both ends of the curved segment 312, which is located in the middle of the spoke assembly 300. The included angle between the two straight segments 311 is 125°. The spokes 310 are staggered, and the curved segments 312 of multiple spokes 310 form an approximately circular shape in the middle of the spoke assembly 300. The curved segments 312 are staggered in the middle of the spoke assembly 300.

[0032] When subjected to external forces, such as the pressure and tension experienced during vehicle operation, the special shape of the curved segment 312 helps to disperse stress, preventing stress concentration at a single point, thus improving the overall strength and durability of the spoke assembly 300 and reducing the risk of breakage due to stress concentration. The structure of the spoke 310 connected to the rim 100 resembles a triangle. When subjected to external forces, the two straight segments 311 support each other, maintaining the shape and position of the spoke 310, making it less prone to deformation and damage during use.

[0033] The carbon fiber ring is positioned at the intersection of the two spokes and at both ends of the curved section. The carbon fiber ring is made by winding carbon fiber around the surface of the spokes and then curing it. The carbon fiber ring 320 is formed by manually winding carbon fiber around the spoke 310 and then placing it into a mold for curing.

[0034] In this embodiment, the manual winding of carbon fiber can be precisely controlled according to the shape and interlacing position of the spokes 310, ensuring that the carbon fiber ring 320 fits tightly against the spokes 310. This tight fit not only ensures the stability of the relative position between the spokes 310, but also effectively transfers stress, preventing component damage due to loosening or gaps, and also preventing the carbon fiber ring 320 from falling off. Furthermore, manual operation allows for better adaptation to different shapes and interlacing patterns of the spokes 310, achieving precise positioning and ensuring the overall structural accuracy of the spoke assembly 300.

[0035] like Figure 4 As shown, the curved segments 312 of multiple spokes 310 overlap sequentially to form a circular inner contour, facilitating installation onto the hub. (Combined) Figure 4 and 8 As shown, the two ends of the curved segment 312 of each spoke 310 are the first interlacing point A and the second interlacing point B, respectively. The two sides of the spoke 310a are the first adjacent spoke 310b and the second adjacent spoke 310c, respectively. The first interlacing point A of the spoke 310a is stacked on the outside of the first adjacent spoke 310b, and the second interlacing point B is stacked on the inside of the second adjacent spoke 310c. Both the first interlacing point A and the second interlacing point B are provided with carbon fiber rings 320. It should be noted that each spoke has a first interlacing point and a second interlacing point. When stacking, the first interlacing point of each spoke is stacked with the second interlacing point of the first adjacent spoke, and the second interlacing point of each spoke is stacked with the first interlacing point of the second adjacent spoke, thus forming a sequentially overlapping spoke group structure.

[0036] In this embodiment, the spoke assembly has six spokes.

[0037] The curved segments 312 of the six spokes 310 overlap sequentially to form a circular inner contour, allowing the spokes 310 to support and restrain each other, thus better withstanding forces from all directions and enhancing the structural stability of the entire spoke assembly 300. The carbon fiber rings 320 placed at the intersection points further reinforce the connection points of the spokes 310, reducing the possibility of deformation or damage due to stress and improving the overall durability of the wheel.

[0038] The carbon fiber ring 320 is positioned at the intersection of two adjacent spokes 310, effectively constraining the relative movement of the spokes 310 and enhancing the structural stability of the entire spoke assembly 300. During the process of winding the carbon fiber and placing it in the mold for curing, parameters such as the number of winding layers, angle, and shape of the mold can be adjusted according to actual needs to meet different design requirements and application scenarios.

[0039] This utility model also discloses a wheel, including a hub, a rim 100 and a spoke assembly 300. The hub includes a hub body 200 and a flange. The flange is detachably mounted on the hub body 200 and is used to mount the spoke assembly 300. The side of the spoke assembly 300 away from the hub is fixedly mounted on the rim 100.

[0040] In this embodiment, the flange is detachably mounted on the hub body 200, making the installation and removal of the spoke assembly 300 more convenient. When the spoke assembly 300 is damaged or needs replacement, only the flange needs to be removed to operate on the spoke assembly 300, eliminating the need for a complex disassembly and installation process of the entire hub, greatly reducing the difficulty and time cost of maintenance. At the same time, this detachable design also facilitates the inspection and replacement of other components of the hub.

[0041] The flange includes a first flange 210 and a second flange 220. A spoke assembly 300 is disposed between the first flange 210 and the second flange 220. The first flange 210 has a first receiving groove 211 for mounting the spokes 310 and a second receiving groove 212 for mounting the carbon fiber ring 320. The second flange 220 has a third receiving groove for mounting the spokes 310 and a fourth receiving groove for mounting the carbon fiber ring 320. The first flange 210 and the second flange 220 are fixedly connected by adhesive.

[0042] The receiving grooves provided on the first flange 210 and the second flange 220 respectively provide precise positioning for the spokes 310 and the carbon fiber ring 320. The first receiving groove 211 mates with the curved section 312 of the spoke assembly 300, the second receiving groove 212 mates with the carbon fiber ring 320, and the third and fourth receiving grooves also accurately mate with the spoke assembly 300, ensuring the correct installation of the spoke assembly 300 on the flange and improving the accuracy and stability of the installation. This precise positioning helps reduce errors during the installation process and ensures the overall performance of the wheel.

[0043] When installing the spoke assembly 300 on the flange, apply an appropriate amount of adhesive to the mounting surfaces of the first flange 210 and the second flange 220. Install the approximately circular structure formed by multiple curved segments 312 in the middle of the spoke assembly 300 onto the first receiving groove 211 on the first flange 210, and install the carbon fiber ring 320 into the second receiving groove 212. Then, move the second flange 220 onto the spoke assembly 300, so that the third and fourth receiving grooves mate with the spoke assembly 300. Wait for the adhesive to dry to complete the installation.

[0044] In this embodiment, the adhesive is glue.

[0045] The spoke assembly 300, flange, and rim 100 are all made of carbon fiber. Carbon fiber has a much lower density than traditional metal materials such as steel and aluminum. Using carbon fiber to manufacture the spoke assembly 300, hub, and rim 100 significantly reduces the weight of the wheel, thereby reducing the overall weight of the vehicle. Carbon fiber possesses excellent strength and rigidity, capable of withstanding significant external forces without deformation or damage. In wheel applications, it effectively resists impacts from the road surface, torque, and various stresses generated during vehicle operation, ensuring the stability and safety of the wheel at high speeds and in complex road conditions, and extending the wheel's lifespan.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
