Technical Field

[0002] A motorcycle is a two- or three-wheeled vehicle powered by a fuel or electric motor and steered by a handlebar. It is lightweight, agile, and fast, and is mainly used for personal transportation, leisure and entertainment, or cargo transport. With technological development, electric motorcycles and intelligent systems are driving their evolution towards environmental protection, safety, and efficiency.
[0003] During motorcycle operation, the wheel hub generates a lot of heat. This heat mainly comes from the friction between the tire and the ground, as well as the operation of the braking system. If the wheel hub does not dissipate heat well, the wheel hub temperature will rise, which will affect the tire performance and lifespan, and may even cause safety hazards such as tire blowout.
[0004] In the current motorcycle wheel hub structure, the spokes bear a large load during use, and the spokes are prone to deformation, breakage and other damage. The spokes are generally straight, which can easily cause turbulent airflow around the wheel hub, making it difficult to guide airflow through the inside of the wheel hub, resulting in poor heat dissipation of the wheel hub.
[0005] Therefore, this utility model provides a motorcycle wheel hub heat dissipation efficiency enhancement structure with optimized airflow. Utility Model Content

[0010] Preferably, the bead seat has multiple through holes; the through holes are distributed in a circumferential array; the above structure enables air to form a convection channel between the inside and outside of the tire, thereby accelerating heat dissipation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 4As shown in the embodiment of this utility model, a motorcycle wheel hub heat dissipation enhancement structure with optimized airflow includes a rotating shaft 1; a central hub 11 is rotatably connected to the middle of the rotating shaft 1; two fixing rings 12 are fixedly connected to the middle of the central hub 11; the two fixing rings 12 are symmetrically arranged; multiple spokes 13 are fixedly connected to the middle of the fixing rings 12; the spokes 13 are distributed in a circumferential array; the spokes 13 are curved; a rim 14 is fixedly connected to the end of the spokes 13; two bead seats 15 are fixedly connected to the middle of the rim 14; the two bead seats 15 are symmetrically arranged; during operation, the central hub 11 is provided with two sets of spokes 13, each set of spokes 13 has multiple spokes, and the outer spokes 13... With its curved shape, the two sets of spokes 13 can distribute the load borne by the entire wheel hub to more components. Each set of spokes 13 only needs to bear a portion of the load. Through this structure, the stress on a single spoke 13 is effectively reduced, the deformation and breakage of spokes 13 are reduced, the service life of the entire wheel hub is extended, and driving safety is improved. The curved shape of the spokes 13 effectively increases the contact area with air, thereby improving heat dissipation. It can also guide air to flow along a specific path, reducing air turbulence and resistance, allowing air to flow more smoothly over the surface of the wheel hub, reducing the drag coefficient and reducing energy loss.
[0026] like Figure 3 As shown, multiple ventilation openings 2 are provided in the middle of the rim 14; the ventilation openings 2 are distributed in a circumferential array; a connecting ring 21 is fixedly connected to the middle of the hub 11; the connecting ring 21 is located between two fixed rings 12; multiple support rods 22 are fixedly connected to the middle of the connecting ring 21; the support rods 22 are distributed in a circumferential array; a fixing block 23 is fixedly connected to the end of the support rod 22; the fixing block 23 is fixedly connected to the rim 14; the fixing block 23 is located near the ventilation openings 2; during operation, ventilation openings 2 are provided on the rim 14 to allow air to circulate between the inside and outside of the rim 14. To accelerate airflow, a support rod 22 is installed near the vent 2 to support the rim 14. This structure effectively removes heat, reduces the temperature of the rim 14 and tire, and minimizes tire aging and performance degradation due to overheating. It also provides a drainage channel for accumulated water, allowing water to flow out of the rim 14 quickly. The support rod 22 can distribute the load on the rim 14, effectively reducing stress concentration at the vent 2 and preventing cracks or deformation of the rim 14 due to uneven stress. It also increases the rigidity of the rim 14.
[0027] like Figure 1 and Figure 4As shown, a first protective cover 3 is slidably connected to the side wall of the spoke 13; a positioning post 31 is fixedly connected to the side wall of the first protective cover 3; the positioning post 31 is located near the end of the first protective cover 3; a second protective cover 32 is slidably connected to the middle of the positioning post 31; a positioning cylinder 33 is fixedly connected to the end of the second protective cover 32; during operation, the spoke 13 is easily impacted by flying stones, sand and other hard objects. By covering the spoke 13 with the first protective cover 3 and the second protective cover 32, and inserting the positioning post 31 into the interior of the positioning cylinder 33, the first protective cover 3 and the second protective cover 32 can be quickly fixed to the spoke 13, thereby protecting the spoke 13 and reducing wear caused by impacts from hard objects. The first protective cover 3 and the second protective cover 32 are easy to disassemble and replace when worn, greatly improving the convenience of use.
[0028] like Figure 1 As shown, the tire bead seat 15 has multiple through holes 4; the through holes 4 are distributed in a circumferential array; during operation, the friction between the motorcycle and the ground generates a large amount of heat. By opening the through holes 4 on the tire bead seat 15, the above structure allows air to form a convection channel between the inside and outside of the tire, thereby accelerating heat dissipation. At the same time, opening the through holes 4 also reduces the weight of the tire bead seat 15, effectively improving the handling performance of the motorcycle.
[0029] like Figure 1 and Figure 2 As shown, there are two sealing gaskets 5 at the end of the rotating shaft 1; the two sealing gaskets 5 are arranged symmetrically; during operation, dust and impurities can easily enter the gap between the rotating shaft 1 and the central hub 11. By setting sealing gaskets 5 at both ends of the rotating shaft 1, the above structure can effectively reduce the entry of dust and impurities between the rotating shaft 1 and the central hub 11, thereby reducing the wear of the rotating shaft 1 and the central hub 11.
[0030] like Figure 1 and Figure 3 As shown, the center hub 11 has multiple threaded holes 6 in the middle; the threaded holes 6 are distributed in a circumferential array; during operation, the center hub 11 is usually connected to mechanisms such as brakes and mudguards. By opening the threaded holes 6 on the center hub 11, the mudguards, brakes and other mechanisms can be connected to the threaded holes 6 by bolts, thereby improving the convenience of use.
[0031] like Figure 3 As shown, the rim 14 is made of aluminum alloy; the surface of the rim 14 is coated with an anti-corrosion layer; when in operation, the rim 14, being made of aluminum alloy, is relatively lightweight, and its surface is provided with an anti-corrosion layer. Through the above structure, the overall weight of the wheel hub can be effectively reduced, improving the handling performance of the motorcycle. The anti-corrosion layer can reduce the erosion of the rim 14 by rainwater and mud, thereby extending the service life of the rim 14.
[0032] During operation, the hub 11 has two sets of spokes 13, each set containing multiple spokes. The spokes 13 are curved in shape. These two sets of spokes distribute the load on the hub to more components, with each set only bearing a portion of the load. This structure effectively reduces the stress on individual spokes 13, minimizing deformation and breakage, extending the overall lifespan of the hub, and improving driving safety. The curved shape of the spokes 13 also increases the contact area with air, improving heat dissipation. Furthermore, it guides air along a specific path, reducing turbulence and resistance, allowing air to flow more smoothly over the hub surface, lowering the drag coefficient, and reducing energy loss. A vent 2 is provided on the rim 14 to create a flow channel between the inside and outside of the rim 14, accelerating airflow. A support rod 22 is installed near the vent 2 to support the rim 14. This structure effectively dissipates heat, reducing the temperature of the rim 14 and tire, minimizing tire aging and performance degradation due to overheating. It also provides a drainage channel for accumulated water, allowing water to flow quickly out of the rim 14. The support rod 22 distributes the load on the rim 14, effectively reducing stress concentration at the vent 2 and preventing cracks or deformation of the rim 14 due to uneven stress. It also increases the rigidity of the rim 14. During motorcycle operation, the spokes 13 are easily splashed. To protect the wheel spokes from impacts from stones, sand, and other hard objects, the first protective cover 3 and the second protective cover 32 are placed over the spokes 13. The positioning pin 31 is inserted into the positioning cylinder 33. This structure allows for quick and easy fixation of the first and second protective covers 3 and 32 to the spokes 13, protecting them and reducing wear caused by impacts. The first and second protective covers 3 and 32 are easy to disassemble and replace when worn, greatly improving usability. The motorcycle generates significant heat through friction with the ground. A through-hole 4 is provided in the tire bead seat 15. This structure allows air to flow between the inside and outside of the tire, accelerating heat dissipation. The through-hole 4 also reduces the burden on the tire. The weight of the rim 15 effectively improves the motorcycle's handling performance. Dust and impurities can easily enter the gap between the shaft 1 and the center hub 11. Sealing gaskets 5 are installed at both ends of the shaft 1. This structure effectively reduces the amount of dust and impurities entering the space between the shaft 1 and the center hub 11, thus reducing wear on both. The center hub 11 typically connects to mechanisms such as brakes and mudguards. Threaded holes 6 are provided on the center hub 11. This structure allows the mudguards, brakes, and other mechanisms to be connected via bolts to the threaded holes 6, improving ease of use. The rim 14 is made of aluminum alloy, making it lightweight. Its surface has an anti-corrosion layer. This structure effectively reduces the overall weight of the wheel hub, improving the motorcycle's handling performance.The anti-corrosion layer reduces the erosion of the wheel rim 14 by rainwater and mud, thereby extending the service life of the wheel rim 14.
