Description

Technical Field

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

[0002] Carbon fiber spokes are high-performance wheel assembly components made of carbon fiber composite materials, combining lightweight, high strength, and high rigidity. Their density is only 1 / 4 that of steel, yet their tensile strength is 2-3 times higher, effectively reducing rotational inertia and improving vehicle acceleration and handling response. Formed through prepreg lamination or three-dimensional weaving processes, they possess anisotropic mechanical properties, allowing for targeted optimization of stress distribution. Compared to metal spokes, carbon fiber offers superior fatigue resistance and vibration damping characteristics, but requires adhesive bonding to the rim / hub. Primarily used in racing bicycles, motorcycles, and high-end sports equipment, careful attention must be paid to lateral rigidity adaptation and shear resistance under impact loads.

[0003] Carbon fiber spokes connect the hub and rim. Existing spoke assembly structures generally fall into the following categories: 1. Interlaced carbon fiber spokes between the hub and rim, with each spoke independently. When the wheel is subjected to external force, the spokes operate independently, easily leading to wobbling, deformation, and even out-of-roundness of the wheel, affecting riding stability. 2. Interlaced spokes are glued together. Glue bonding is prone to hollow spots, causing spokes to wobble, and over time, the glue may peel off. 3. Interlaced spokes are clamped together. The clamps increase the weight of the carbon fiber wheelset and affect its appearance. Summary of the Invention

[0004] The purpose of this invention is to provide a carbon fiber spoke assembly and wheel assembly to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model discloses a carbon fiber spoke assembly, comprising: a flange, multiple spokes, and multiple connectors; the multiple spokes are mounted on the flange or integrally formed with the flange, and the spokes are staggered with each other; the connectors are disposed at the gaps between the staggered positions and are fixedly connected to two staggered spokes; the spokes are made of carbon fiber material, and the connectors are made of fiber material.

[0006] Preferably, the connector is formed by a fiber spiral.

[0007] Preferably, the connector is formed by spiraling carbon fiber.

[0008] Preferably, the spokes include two straight segments and one curved segment, the two straight segments are respectively connected to the two ends of the curved segment, the curved segment is mounted on the flange, and multiple spokes are arranged around the flange, with the straight segments intersecting each other.

[0009] Preferably, the included angle between two straight segments of the same spoke is 100-170°.

[0010] Preferably, the flange has a mounting groove on its side for mounting spokes.

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

[0016] 1. This invention securely connects two intersecting spokes by filling the gaps at their intersections with fiber material.

[0027] 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.

[0028] like Figures 1-8 This utility model provides a carbon fiber spoke assembly, comprising: a flange 110, multiple spokes 200, and multiple connectors 400; the multiple spokes 200 are mounted on or integrally formed with the flange 110, and are staggered among themselves; the connectors 400 are disposed at the gaps between the staggered positions and are fixedly connected to the staggered spokes 200; the spokes 200 are made of carbon fiber material, and the connectors 400 are made of fiber material. The spokes 200 can be straight or curved, and the ends of the spokes 200 near the hub are staggered, that is, the spokes 200 adopt a cross-weaving method. The connectors 400 are disposed at the intersection of two straight segments 210, and both ends of the connectors 400 are fixedly connected to the two spokes 200 respectively. The connectors 400 are formed by spirally winding fibers. The fibers are wound around the two spokes 200 one circle at a time to form the connectors 400.

[0029] In this embodiment, the spoke 200 includes two straight segments 210 and one curved segment 220. The two straight segments 210 are respectively connected to the two ends of the curved segment 220. The curved segment 220 is mounted on the flange 110. Multiple spokes 200 are arranged around the flange 110, and the straight segments 210 are interlaced. The included angle between the two straight segments 210 of the same spoke 200 is 125°.

[0030] The spokes 200 are interlaced at the ends furthest from the hub and connected at the intersections by connectors 400. This structure creates a mutually supporting network among the spokes 200, which can more effectively distribute various forces from the rim and during riding, such as pressure, tension, and impact.

[0031] In this embodiment, the connector 400 is made of carbon fiber spirally wound around the spokes. The spokes 200 are also made of carbon fiber spirally wound around the spokes 200. The connector 400 is positioned between the spokes 200. During the curing process, the resin on the carbon fiber undergoes a cross-linking reaction at the contact surface, connecting them together. The connector 400 firmly connects the two intersecting spokes 200 at their intersection, helping to more evenly transmit and distribute force between the spokes 200, thereby reducing the swaying and deformation of the spokes 200 and making the riding experience smoother.

[0032] The flange 110 has mounting grooves 111 on its side for mounting spokes 200. The mounting grooves 111 are angled and positioned on the side of the flange 110, with the ends of adjacent mounting grooves 111 interconnected. Spokes 200 are fixedly connected to the flange 110 using adhesive. In this embodiment, the mounting grooves 111 provide a precise mounting position for the spokes 200, allowing them to be accurately mounted on the flange 110. This ensures the consistency and accuracy of spoke installation, improving the overall assembly quality and performance stability of the wheel. The mounting grooves 111 increase the contact area between the spokes 200 and the flange 110, and the adhesive connection allows the adhesive to function better, increasing the strength of the connection and effectively preventing the spokes 200 from detaching from the flange 110, thus improving wheel safety.

[0033] This utility model also discloses a wheelset, including a rim 300, a hub body 100, and a carbon fiber spoke assembly. A flange 110 is mounted on or integrally formed with the hub body 100. The flange 110 is made of carbon fiber material. The end of the spoke 200 away from the flange 110 is fixedly connected to the rim 300. The rim 300 is an important component of the wheel. It works with the hub, spokes 200, etc., to enable the wheel to rotate smoothly around the axle.

[0034] Compared to traditional metal spokes, carbon fiber spokes can significantly reduce the overall weight of a wheelset. This weight reduction positively impacts the handling, acceleration performance, and fuel economy of vehicles (such as bicycles and motorcycles). For example, in cycling, a lightweight wheelset allows riders to climb hills and accelerate more easily. Carbon fiber materials possess excellent tensile strength, enabling them to withstand significant tension and stress. This allows the wheelset to maintain good structural stability even under complex road conditions and high-intensity use, reducing the risk of spoke breakage and extending the wheelset's lifespan.

[0035] 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.
