Description

Technical Field

[0001] This utility model relates to the field of spoke technology, and in particular to a novel wind-breaking spoke and vehicle. Background Technology

[0002] Spokes are a crucial component of wheelsets, forming the supporting framework for the entire wheel assembly. With technological advancements, spokes have evolved from traditional circular cross-sections to teardrop-shaped cross-sections and other aerodynamically more efficient wind-breaking structures. Some spoke structures, such as the Chinese patent CN220594525U (titled "A Novel Spoke Structure and its Wheel"), utilize the design of the windward and leeward sections and their angles to reduce drag during spoke movement, thereby reducing wheel drag and increasing riding speed. This spoke structure is suitable for wheels with large spoke cross-sections and where the spoke rod is integrally formed with the rim. However, this structure has limitations: the spoke rod tension is not adjustable, and if one spoke is damaged, the entire rim must be replaced. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel aerodynamic spoke and vehicle, wherein the novel aerodynamic spoke includes: The spoke body includes a windward portion and a leeward portion, with a fitting portion between the windward portion and the leeward portion. The windward portion includes several windward surfaces, and the leeward portion includes several leeward surfaces. The angle between the windward surface and the fitting portion is 50°-75°, and the angle between the leeward surface (121) and the fitting portion is 15°-35°. A connector, located at the end of the spoke body, is used for detachably connecting to a hub or rim.

[0004] Preferably, the connector is a cap or a toothed cap; the outer wall end of the cap is provided with a limiting protrusion for connecting to the hub; the outer wall end of the toothed cap is provided with a thread for connecting to the wheel rim.

[0005] Preferably, the connector is provided with a mounting hole, and the inner wall of the mounting hole is provided with two or more annular protrusions spaced apart along the axial direction.

[0006] Preferably, the end of the annular protrusion is a plane.

[0007] This utility model also provides a vehicle that uses any of the novel wind-breaking spokes described above.

[0008] The novel wind-breaking spokes provided by this utility model, through the setting of the windward and leeward portions and their angles, enable the vehicle to break through the wind and reduce the impact of crosswind resistance during driving, thus ensuring the vehicle's speed. By setting a connector on the spoke body to achieve detachable connection with the hub and rim, the problem of existing wind-breaking spokes that are integrally molded with the rim can only be replaced along with the rim when one of the spokes is damaged is solved, thus improving the maintainability and economy of the spoke body.

[0013] like Figures 1-5 As shown, this utility model provides a novel aerodynamic spoke and vehicle, wherein the novel aerodynamic spoke includes: Spoke body 10, the spoke body 10 including a windward portion 11 and a leeward portion 12, such as Figure 2 As shown, the cross-section of the middle part of the spoke body 10 is quadrilateral, and both the windward part 11 and the leeward part 12 are V-shaped, with the included angle of the windward part 11 being smaller than the included angle of the leeward part 12; there is a fitting part (such as...) between the windward part 11 and the leeward part 12. Figure 2 As indicated by the dotted lines in the diagram), the windward portion 11 includes several windward surfaces 111, and the leeward portion 12 includes several leeward surfaces 121. The included angle between the windward surface 111 and the fitting portion is 50°-75° (as shown in the diagram). Figure 2 (e.g., angle B), the included angle between the leeward side (121) and the fitting part is 15°-35° (e.g., angle B). Figure 2 (C) In the middle, by setting the windward part 11 and the leeward part 12 and their angles, the vehicle can break through the wind and reduce the impact of crosswind resistance when driving, so as to ensure the driving speed of the vehicle; The connector 20 is made of, but is not limited to, a material selected from metal, carbon fiber, and alloy. The connector is located at the end of the spoke body 10 and is used for detachable connection to the hub or rim. The connector 20 is a cap or a toothed cap. The outer wall end of the cap has a limiting protrusion 21 for connecting to the hub. The outer wall end of the toothed cap has a thread 22 for connecting to the rim. Detachable connection of the spoke body 10 through caps, toothed caps, etc. is existing technology and will not be described in detail here.

[0014] The novel wind-breaking spoke provided in this embodiment of the utility model, through the setting of the windward part 11 and the leeward part 12 and their angles, enables the vehicle to break through the wind and reduce the impact of crosswind resistance when driving, thus ensuring the vehicle's driving speed. By setting a connector on the spoke body 10, a detachable connection with the hub and rim can be achieved, thereby solving the problem of existing wind-breaking spokes that are integrally formed with the rim and can only be replaced along with the rim when one of the spokes is damaged, thus improving the maintainability and economy of the spoke body 10.

[0015] Preferably, the spoke body 10 may also be polygonal (with more than four sides), such as the windward surface 111 being multi-segmented and bent.

[0016] Furthermore, such as Figure 3 , Figure 4 As shown, the connector 20 has a thread or limiting protrusion 21 on its outer wall for connecting the wheel rim or hub. The connector 20 has a through mounting hole 23 for inserting the end of the spoke body 10. The inner wall of the mounting hole 23 is provided with two or more annular protrusions 24 spaced apart along the axial direction (e.g., ...). Figure 3 As shown), the end of the annular protrusion 24 (as shown) Figure 5 The shape (as shown) includes, but is not limited to, a flat surface 241, a sharp edge, or rounded corners; by providing two or more spaced annular protrusions 24 on the inner wall of the mounting hole 23, the single step structure in the prior art is replaced, and these annular protrusions 24 form multiple limiting points; when the yarn covering layer at the end of the spoke body 10 is pulled into the hole, the yarn covering material will embed and be stuck in the groove formed between adjacent annular protrusions 24, significantly increasing the resistance required for axial movement of the yarn covering layer and reducing the pull-out phenomenon at the end of the yarn covering. The connector 20 structure in this embodiment can be applied to structures with a circular, elliptical, or irregular cross-section at the end of the spoke body 10, improving the versatility and practicality of the connector.

[0017] Preferably, the annular protrusion 24 is an integral structure in the radial direction of the connector 20 or is composed of several spaced protrusions surrounding it. In this embodiment, different annular protrusion 24 structural designs are provided to meet different strength, cost and processing requirements and improve flexibility.

[0018] Furthermore, the end of the annular protrusion 24 is a flat surface 241, which, compared to sharp edges or rounded corners, allows for a larger contact area between the annular protrusion 24 and the yarn covering layer, dispersing local pressure; reducing stress concentration / cutting, protecting the yarn covering layer, and improving the reliability and durability of the connection.

[0019] And, as Figure 5 As shown, the edge of the plane 241 is provided with a surrounding rounded chamfer 2411, thereby eliminating any minor burrs or sharp points that may exist at the edge of the plane, and making the transition between the plane and the hole wall or adjacent protrusions smoother. In addition, it can reduce the risk of the yarn covering layer being scratched or torn during installation or under stress, which is an optimized design to protect the yarn covering layer and ensure long-term reliability.

[0020] This utility model also provides a vehicle that uses any of the novel wind-breaking spokes described above.
