Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle wheel design, in particular to a vehicle wheel with spiral spokes. BACKGROUND

[0002] In existing vehicle designs, the wheel is a key component that connects the tire and the axle, and its structural design directly affects the vehicle's handling stability, driving safety, and tire life. Currently, most wheels use a straight spoke or a simple curved spoke design. This design has the following technical problems during vehicle driving, especially when turning or under lateral force impact:

[0003] 1. Insufficient lateral stiffness: Straight spoke design is prone to bending deformation when subjected to lateral force, resulting in insufficient lateral stiffness of the wheel, affecting the vehicle's handling and stability. Lateral stiffness is an important indicator of a wheel's ability to resist lateral force deformation. Low lateral stiffness means that the wheel is prone to deformation under lateral force, which in turn affects the tire's contact area and reduces the vehicle's handling performance.

[0004] 2. Stress concentration: The existing spoke design is prone to stress concentration at the connection between the spoke and the wheel center, which not only reduces the strength of the wheel but also shortens its fatigue life. Stress concentration refers to the discontinuity of the structure's geometry (such as holes, slots, angles, etc.), which causes the local stress to increase significantly, exceeding the material's strength limit, and thus causing cracks or fractures.

[0005] 3. Heavy weight: To improve the strength and stiffness of the wheel, the existing design often needs to increase the thickness of the material, which results in a heavier wheel. The increased weight not only affects the vehicle's fuel economy but also reduces the vehicle's overall performance, including acceleration, braking effect, and suspension system response speed.

[0006] 4. Poor aerodynamic performance: Straight spoke or simple curved spoke designs often ignore aerodynamic effects, resulting in increased wind resistance for the vehicle at high speeds, affecting fuel efficiency and driving stability.

[0007] To address the above problems, existing technologies attempt to improve wheel performance by increasing the number of spokes, optimizing spoke materials, etc. However, these methods can only alleviate the problem to some extent and cannot fundamentally solve the problems of insufficient lateral stiffness, stress concentration, and excessive weight of the wheel. Moreover, the existing design and layout of the wheel's ventilation holes are not reasonable, resulting in unsmooth airflow through the wheel. SUMMARY

[0015] In an exemplary embodiment, the cross-sectional shape of the hole section of each vent hole is uniform; or, the cross-sectional shape of the hole section of two adjacent vent holes is not uniform; or, the cross-sectional shape of the hole section of the vent hole is at least one of a triangle, a circle, a square, and an ellipse.

[0016] In an exemplary embodiment, the central mounting disc and the plurality of spiral spokes are bowl-shaped in a radial cross-section of the spoke; and the distance L between the lowest point of the bowl-shaped spoke and the highest point of the spiral spoke satisfies: 50mm≤L≤65mm.

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work, fall within the scope of protection of the present application.

[0031] In order to solve the problems of insufficient lateral stiffness, stress concentration, and excessive weight of the wheel in the prior art, and the unreasonable design and layout of the vent hole of the wheel, which leads to the incoherent airflow through the wheel, the present application provides a wheel with a spiral spoke.

[0032] As Figures 1 to 3As shown, the wheel with spiral spokes includes a rim 10 and a spoke 20, wherein the spoke 20 is arranged at one axial end of the rim 10; wherein the spoke 20 includes a center mounting disc 21, a plurality of spiral spokes 22, and a spoke outer rim 23, the inner side of each of the plurality of spiral spokes 22 is connected with the center mounting disc 21 and located at the outer circumferential side of the center mounting disc 21, the outer side of each of the plurality of spiral spokes 22 is connected with the spoke outer rim 23, the spoke outer rim 23 is connected with the rim 10, at least one ventilation hole 221 is formed between two adjacent spiral spokes 22 in the plurality of spiral spokes; wherein the extension direction of the spiral spoke 22 deviates from the radial direction of the spoke 20; the center mounting disc 21 has a plurality of groups of ventilation holes, the plurality of groups of ventilation holes are arranged at intervals around the circumference of the spoke 20, each group of ventilation holes includes a plurality of ventilation holes 221; the cross-sectional area of the hole section of each ventilation hole 221 in at least the same group of ventilation holes is consistent; the cross-sectional area of the hole section of each ventilation hole 221 in at least two groups of ventilation holes is inconsistent.

[0033] By setting the extension direction of the spiral spoke 22 to deviate from the radial direction of the spoke 20, at least part of the lateral force borne by the wheel is converted into axial force, thereby effectively improving the lateral stiffness of the wheel. The implementation effect is that when the vehicle is turning or subjected to lateral force impact, the steering stability, driving safety, and tire life can be significantly improved. Application scenarios include various types of vehicles, such as cars, motorcycles, bicycles, etc., and are particularly suitable for sports vehicles that pursue high performance and high safety. During vehicle driving, the design of the spiral spoke 22 can continuously optimize the stress distribution of the wheel, improve the lateral stiffness, and thus maintain the stability and safety of the vehicle under various road conditions.

[0034] In addition, by setting the cross-sectional area of the hole section of each ventilation hole 221 in at least the same group of ventilation holes to be consistent, and setting the cross-sectional area of the hole section of each ventilation hole 221 in at least two groups of ventilation holes to be inconsistent, the following beneficial effects are achieved:

[0035] 1) It is beneficial to optimize the distribution of air flow, specifically, different sizes of ventilation holes 221 can change the flow direction and flow rate of air flow through the wheel, which helps to improve the cooling efficiency of the wheel. By designing different sizes of ventilation holes 221, the air flow can flow more smoothly through the wheel, carrying away more heat, thereby reducing the temperature of the wheel and brake system, prolonging its service life. 2) It is beneficial to reduce wind noise, specifically, the size difference of the ventilation holes 221 can reduce the noise generated by the airflow, and the airflow passing through the ventilation holes 221 of different sizes will produce different frequency sounds. By reasonably optimizing the size and position of the ventilation holes 221, the noise frequency can be effectively dispersed, and the intensity of the noise of a specific frequency can be reduced, thereby reducing the impact of wind noise on the driving experience. 3) It is beneficial to enhance the visual effect, specifically, in terms of appearance design, different sizes of ventilation holes 221 can increase the visual appeal of the wheel, making its appearance more unique and dynamic, greatly improving the user's experience and satisfaction, and meeting the user's pursuit of individualization and design. 4) It is beneficial to reduce weight, specifically, under the premise of ensuring the overall structural strength and rigidity of the wheel, by adjusting the size and distribution of the ventilation holes 221, the amount of material used is effectively reduced, thereby reducing the overall weight of the wheel and ensuring the lightweight design of the wheel. 5) It is beneficial to improve the aerodynamic performance, specifically, by optimizing the size and layout of the ventilation holes 221, it is beneficial to improve the aerodynamic performance of the vehicle, reduce wind resistance during driving, and thus improve the driving speed and stability of the vehicle. 6) It is beneficial to improve the overall stress distribution of the wheel and reduce stress concentration, thereby improving the impact resistance and overall safety of the wheel.

[0036] As shown in Figure 1 and Figure 3 , among the plurality of spiral spokes 22, the included angle between the extension direction of the adjacent two spiral spokes 22 and the radial direction of the spoke 20 is different, so that the lengths of the adjacent two spiral spokes 22 are not equal. In this way, the spiral spokes 22 of different lengths optimize the force distribution of the wheel when it is subjected to load, and the longer spiral spokes 22 can provide a larger contact area, which helps to disperse stress and reduce stress concentration, thereby improving the overall structural strength and durability of the wheel.

[0037] It should be noted that in some embodiments, as shown in Figure 1 and Figure 3 , the rotation directions of the plurality of spiral spokes 22 are consistent, Figure 1 and Figure 3 , the rotation directions of the plurality of spiral spokes 22 in

[0038] Of course, in an embodiment of the present application not shown in the figure, the rotation directions of the plurality of spiral spokes are all counterclockwise.

[0039] It should be noted that, in some embodiments, the adjacent two adjacent spiral spokes 22 of the plurality of spiral spokes 22 are opposite in rotation direction.

[0040] Optionally, each spiral spoke 22 extends along a straight line.

[0041] Optionally, each spiral spoke 22 extends along a curve.

[0042] Optionally, a part of the plurality of spiral spokes 22 extend along a straight line, and the rest of the plurality of spiral spokes 22 extend along a curve.

[0043] As shown in Figure 1 and Figure 3 , a plurality of groups of ventilation holes are arranged around the circumference of the spoke 20. In this way, the overall force uniformity of the wheel is ensured, thereby ensuring the service life of the wheel.

[0044] It should be noted that, in an embodiment not shown in the present application, the hole circumference of each ventilation hole 221 has a flange structure extending in the axial direction of the spoke 20. The folding direction of the flange structure of at least one of the ventilation holes 221 is consistent; or, at least one of the flange structures of the same group of ventilation holes is partially directed towards the inside of the spoke 20 and the other part is directed towards the outside of the spoke 20; or, the folding direction of each flange structure of at least one group of ventilation holes is consistent; or, the folding direction of the adjacent two flange structures of at least one group of ventilation holes is inconsistent; or, the folding direction of each flange structure of at least two groups of ventilation holes is inconsistent. In this way, the flange structure of the hole circumference of the ventilation hole 221 increases the material thickness and rigidity of the ventilation hole 221, which helps to improve the overall structural strength of the wheel, effectively prevents the ventilation hole from deforming or being damaged during long-term use or under external force impact, and helps to ensure the service life of the wheel; in addition, the flange structure can guide the airflow through the ventilation hole 221, guide the airflow to cool the wheel and brake disc more effectively, improve the heat dissipation efficiency of the wheel, reduce the operating temperature of the wheel and the brake system, and ensure that they can maintain good performance under high temperature.

[0045] It should be noted that, in the present application, the cross-sectional shape of each ventilation hole 221 is consistent. In this way, while ensuring the overall aesthetic appearance of the wheel, it is also beneficial to reduce the difficulty of manufacturing the wheel.

[0046] It should be noted that, in the present application, the cross-sectional shape of the adjacent two ventilation holes 221 is inconsistent. In this way, it is beneficial to improve the overall aesthetic appearance of the wheel and ensure the personalization of the wheel.

[0047] Further, the cross-sectional shape of the ventilation hole 221 is at least one of a triangle, a circle, a square, and an ellipse.

[0048] As shown in Figure 1 and Figure 3 The cross-sectional shape of the hole section of the vent hole 221 is triangular.

[0049] As shown in Figure 2 The bowl-shaped spoke 20 between the lowest point of the center mounting disc 21 and the highest point of the spiral spoke 22 satisfies: 50mm≤L≤65mm. In this way, by reasonably optimizing the distance L between the bowl-shaped spoke 20 between the lowest point of the center mounting disc 21 and the highest point of the spiral spoke 22, the shape and mechanical properties of the spoke 20 are adjusted, so that the structural strength and rigidity of the spoke 20 when bearing the load of the vehicle are more reasonable, which helps to balance the distribution of materials, reduce stress concentration, improve the overall structural strength and rigidity of the wheel, and reduce the risk of deformation and damage of the spoke 20; in addition, the dynamic balance performance of the wheel is improved, so that the wheel can rotate more stably, reducing the vibration and unnecessary noise of the wheel, thereby improving the driving experience and comfort.

In this way, it is beneficial to ensure that the cross-sectional area of the hole section of each vent hole 221 in the first group of vent hole groups can be different from the cross-sectional area of the hole section of each vent hole 221 in the second group of vent hole groups.

[0051] As shown in Figure 3 An embodiment of the present application includes a first group of vent hole groups and a second group of vent hole groups, wherein the cross-sectional area of the hole section of the vent hole 221 in the first group of vent hole groups is greater than the cross-sectional area of the hole section of the vent hole 221 in the second group of vent hole groups, and the hole section of the vent hole 221 in the first group of vent hole groups and the hole section of the vent hole 221 in the second group of vent hole groups are both triangular.

[0052] As shown in Figure 1 and Figure 3 A plurality of bolt holes 211 are formed on the center mounting disc 21, and the plurality of bolt holes 211 are uniformly distributed around the circumference of the center mounting disc 21, and the bolt hole 211 is used for the connection between the wheel and the axle. In this way, the plurality of bolt holes 211 ensure the reliability of the connection between the wheel and the axle.

[0053] The application sets the extension direction of the spiral spokes 22 to deviate from the radial direction of the spokes 20, so that at least part of the lateral force borne by the wheel is converted into an axial force, effectively improving the lateral stiffness of the wheel. The implementation effect is that when the vehicle turns or is impacted by a lateral force, the handling stability, driving safety and tire life can be significantly improved. Application scenarios include various types of vehicles such as cars, motorcycles, bicycles, etc., and are especially suitable for sports vehicles that pursue high performance and high safety. During vehicle driving, the design of the spiral spokes 22 can continuously optimize the stress distribution of the wheel, improve the lateral stiffness, and thus maintain the stability and safety of the vehicle under various road conditions.

[0054] In addition, the application sets the cross-sectional area of the hole section of each vent hole 221 in at least the same group of vent hole groups to be uniform, and sets the cross-sectional area of the hole section of each vent hole 221 in at least two groups of vent hole groups to be inconsistent, which has the following beneficial effects:

[0055] 1) It is beneficial to optimize the distribution of airflow. Specifically, different sizes of vent holes 221 can change the flow direction and flow rate of airflow passing through the wheel, which helps to improve the cooling efficiency of the wheel. By designing vent holes 221 of different sizes, airflow can flow more smoothly through the wheel, carrying away more heat, thereby reducing the temperature of the wheel and brake system and prolonging their service life. 2) It is beneficial to reduce wind noise. Specifically, the size difference of the vent holes 221 can reduce the noise generated by airflow. When airflow passes through vent holes 221 of different sizes, it will produce different frequencies of sound. By reasonably optimizing the size and position of the vent holes 221, the noise frequency can be effectively dispersed, and the intensity of the noise at a specific frequency can be reduced, thereby reducing the impact of wind noise on the driving experience. 3) It is beneficial to enhance the visual effect. Specifically, in terms of appearance design, different sizes of vent holes 221 can increase the visual appeal of the wheel, making its appearance more unique and dynamic, greatly improving the user's experience and satisfaction, and meeting the user's pursuit of individuality and design. 4) It is beneficial to reduce weight. Specifically, under the premise of ensuring the overall structural strength and rigidity of the wheel, by adjusting the size and distribution of the vent holes 221, the amount of material used is effectively reduced, thereby reducing the overall weight of the wheel and ensuring the lightweight design of the wheel. 5) It is beneficial to improve the aerodynamic performance. Specifically, by optimizing the size and layout of the vent holes 221, it is beneficial to improve the aerodynamic performance of the vehicle, reduce wind resistance during driving, and thus improve the driving speed and stability of the vehicle. 6) It is beneficial to improve the overall stress distribution of the wheel and reduce stress concentration, thereby improving the impact resistance and overall safety of the wheel.
