Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to an improvement in the structure of wheel spokes. Background Technology

[0002] In the existing technology, the structure of the wheel spokes is unreasonable. In order to ensure that the overall strength of the wheel meets the design requirements, it is usually necessary to set a certain thickness for the plate-shaped spokes. This will result in the overall weight of the wheel being too large, which is not conducive to the lightweight design of the wheel. During the vehicle start-up process, the engine needs to provide enough energy to make the wheel rotate, which also increases the energy consumption during the vehicle's operation, which is not conducive to the low energy consumption design of the vehicle. Summary of the Invention

[0003] The main objective of this invention is to provide a wheel spoke and a wheel having the same, in order to solve the problem that the structure of the wheel spoke in the prior art is unreasonable, resulting in an excessively heavy overall wheel, which is not conducive to the lightweight design of the wheel and causes excessive energy consumption of the vehicle.

[0004] To achieve the above objectives, according to one aspect of the present invention, a wheel spoke is provided having a hollow cavity to reduce the weight of the wheel spoke.

[0005] Furthermore, the spokes include a central mounting plate and spokes, with a hollow cavity formed on the central mounting plate and / or spokes.

[0006] Furthermore, there are multiple spokes, which are radially spaced around the central mounting plate. The multiple spokes and the central mounting plate together form a hollow cavity.

[0007] Furthermore, the spokes include a spoke housing and a spoke cover plate, wherein the spoke housing has a groove structure, and the spoke cover plate is placed on the spoke housing and covers the groove structure, so as to splice with the spoke housing to form a hollow cavity.

[0008] Furthermore, the portion of the spoke housing located at the center mounting plate protrudes into the hollow cavity, while the portion of the spoke cover plate located opposite the center mounting plate protrudes away from the hollow cavity.

[0009] Furthermore, the thickness of the spoke cover and the spoke housing is greater than 0 and less than or equal to 4 mm.

[0010] Furthermore, the central mounting plate has a central through hole and multiple mounting holes spaced around the outer periphery of the central through hole. The spokes also include a central cylinder and multiple mounting cylinders. The central cylinder is placed inside the central through hole to block the opening structure of the hollow cavity at the central through hole. The multiple mounting cylinders are correspondingly placed inside the multiple mounting holes to block the opening structure of the hollow cavity at each mounting hole.

[0011] Furthermore, the outer wall surface of each mounting cylinder is welded to the inner wall surface of each mounting hole.

[0012] Furthermore, the cross-section of the hollow cavity at the spoke position is one of a circle, an ellipse, or a polygon.

[0013] According to another aspect of the invention, a wheel is provided, comprising a rim and spokes, the spokes being disposed at one axial end of the rim, and the spokes being the spokes described above.

[0014] The present invention provides a wheel spoke with a hollow cavity, which reduces the weight of the wheel spoke and is beneficial to the lightweight design of the wheel.

[0015] Specifically, while ensuring that the structural strength of the spokes does not affect the overall structural strength of the wheel, the structure of the spokes is optimized to have a hollow cavity, which reduces the weight of the spokes. This is conducive to the lightweight design of the wheel. During the process of the vehicle starting from a standstill, the lighter weight of the wheel ensures that the engine can start the vehicle quickly in a short time, improving the vehicle's acceleration performance and effectively reducing the vehicle's energy consumption.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] To address the problem of excessive wheel weight and high vehicle energy consumption caused by the unreasonable structure of wheel spokes in existing technologies, which hinders lightweight wheel design, this invention provides a wheel spoke and wheel, such as... Figure 1 As shown, the wheel includes a rim 20 and spokes 10. The spokes 10 are disposed at one end of the axial direction of the rim 20, and the spokes 10 are the spokes described above and below.

[0024] like Figure 2 As shown, the spoke 10 has a hollow cavity 11 to reduce the weight of the spoke 10.

[0025] This application provides a wheel spoke 10 with a hollow cavity 11, which reduces the weight of the wheel spoke 10 and is beneficial to the lightweight design of the wheel.

[0026] Specifically, under the premise of ensuring that the structural strength of the spokes 10 does not affect the overall structural strength of the wheel, the structure of the spokes 10 is optimized so that the spokes 10 have a hollow cavity 11, which reduces the weight of the spokes 10. This is conducive to the lightweight design of the wheel. During the process of the vehicle starting from a standstill, the lighter weight of the wheel ensures that the engine can start the vehicle quickly in a short time, improving the vehicle's acceleration performance and effectively reducing the vehicle's energy consumption.

[0027] like Figures 1 to 3 As shown, the wheel spoke 10 includes a center mounting plate 12 and spokes 13, with a hollow cavity 11 formed on the center mounting plate 12 and spokes 13. This greatly reduces the weight of the wheel spoke 10, which is beneficial for the lightweight design of the wheel.

[0028] It should be noted that, in an embodiment of this application (not shown), the spoke 10 includes a central mounting plate 12 and spokes 13, with a hollow cavity 11 formed on the central mounting plate 12. This reduces the weight of the spoke 10 while ensuring sufficient structural strength for the spoke 10 because the spokes 13 are solid structures.

[0029] It should be noted that, in one embodiment of this application (not shown), the spoke 10 includes a central mounting plate 12 and spokes 13, with a hollow cavity 11 formed on the spokes 13. This reduces the weight of the spoke 10 while ensuring sufficient structural strength because the central mounting plate 12 is a solid structure.

[0030] like Figure 1 and Figure 2 As shown, there are multiple spokes 13, which are radially spaced around the central mounting plate 12. The multiple spokes 13 and the central mounting plate 12 together form a hollow cavity 11. This ensures that the hollow cavity 11 is evenly distributed on the spokes 10, thereby ensuring a uniform weight distribution of the spokes 10 and ensuring that the spokes 10 remain coaxial with the rim 20 during wheel rotation.

[0031] like Figure 2 and Figure 3 As shown, the wheel spoke 10 includes a wheel spoke housing 14 and a wheel spoke cover plate 15. The wheel spoke housing 14 has a groove structure 141. The wheel spoke cover plate 15 covers the wheel spoke housing 14 and conceals the groove structure 141, so as to splice with the wheel spoke housing 14 to form a hollow cavity 11. In this way, by setting the wheel spoke 10 into a structure including the wheel spoke housing 14 and the wheel spoke cover plate 15, it is beneficial to reduce the processing and manufacturing difficulty of the wheel spoke 10, thereby improving the economy of the wheel.

[0032] It should be noted that in this application, the spoke housing 14 and the spoke cover plate 15 are connected by welding to ensure the reliability of the connection between the two.

[0033] like Figure 2 and 3 As shown, the portion of the spoke housing 14 located at the center mounting plate 12 protrudes into the hollow cavity 11, while the portion of the spoke cover plate 15 located opposite the center mounting plate 12 protrudes away from the hollow cavity 11. This ensures that the center mounting plate 12 of the spoke 10 has a hollow cavity 11 communicating with the spokes 13 without affecting the overall appearance of the spoke 10, thereby guaranteeing a uniform weight distribution of the spoke 10 and preventing eccentricity of the spoke 10 during wheel rotation.

[0034] It should be noted that in this application, the thickness of the spoke cover plate 15 and the spoke housing 14 is greater than 0 and less than or equal to 4 mm. In this way, by optimizing the thickness of the spoke cover plate 15 and the spoke housing 14, while ensuring that the spokes 10 have sufficient strength, the overall volume of the spokes 10 is avoided from increasing due to excessive thickness of the spoke cover plate 15 and the spoke housing 14, and the spokes 10 does not occupy too much axial space of the rim 20.

[0035] like Figure 1 and Figure 2 As shown, the central mounting plate 12 has a central through hole 121 and a plurality of mounting holes 122 spaced around the outer periphery of the central through hole 121. The wheel spoke 10 also includes a central cylinder 16 and a plurality of mounting cylinders 17. The central cylinder 16 is disposed within the central through hole 121 to seal the opening structure of the hollow cavity 11 at the central through hole 121. The plurality of mounting cylinders 17 are disposed one-to-one within the plurality of mounting holes 122 to seal the opening structure of the hollow cavity 11 at each mounting hole 122. In this way, since both the central mounting plate 12 and the spokes 13 of the wheel spoke 10 have hollow cavities 11, and by disposing of the central cylinder 16 within the central through hole 121, the contact area between the wheel and the axle is increased, ensuring the stability of the wheel installation and thus preventing any shaking between the wheel and the axle during vehicle operation. In addition, disposing of the plurality of mounting cylinders 17 one-to-one within the plurality of mounting holes 122 ensures that the fasteners can reliably secure the wheel and the axle, thereby ensuring the reliability of the wheel-axle connection.

[0036] It should be noted that in this application, the central cylinder 16 is installed in the central through hole 121 by welding, thus ensuring the stability of the installation of the central cylinder 16.

[0037] It should be noted that in this application, the outer wall surface of each mounting cylinder 17 is welded to the inner wall surface of each mounting hole 122. This ensures the stability of the mounting cylinder 17.

[0038] It should be noted that, in this application, provided that the structural strength of the spokes 10 is ensured, the cross-section of the hollow cavity 11 at the position of the spokes 13 may optionally be one of a circle, an ellipse or a polygon.
