Description

Technical Field

[0001] The present invention belongs to the technical field of non-pneumatic tires, and in particular relates to a non-pneumatic tire spoke and a non-pneumatic tire using the spoke. Background Art

[0002] In recent years, with the increase in vehicle speeds, the expansion of driving environments, and the improvement in people's safety requirements, the limitations of traditional pneumatic tires have gradually become apparent, such as the need to maintain appropriate internal air pressure, the need for regular maintenance, complex manufacturing processes, and the susceptibility to blowouts, which can cause a series of fatal accidents. Therefore, non-pneumatic tires came into being.

[0003] Non-pneumatic tires are structurally load-bearing tires, and their structure generally includes a hub, spokes, and a tread. In addition to the stiffness and strength requirements for the tread that contacts the ground, the design of the spokes is one of the most critical components affecting the performance of non-pneumatic tires. The spokes connecting the tread and hub need to transfer the load to the tread and hub, while also bearing a portion of the load themselves. Furthermore, they also need to maintain internal air pressure similar to that of a pneumatic tire, providing support, shock absorption, and impact resistance. Spoke designs vary, including mechanical elastic rings, V-shaped support structures with a negative Poisson's ratio, regular hexagonal 3D-printed thermoplastic polyurethane materials, and elastic metal mesh. The most widely used of these is the V-shaped support structure.

[0004] In the prior art, the V-shaped support structures nested in sequence in the spokes are generally designed with the same thickness on both sides. When the spokes are under load, the two sides of the V-shaped support structure will produce a large deformation until they offset the two sides of the adjacent V-shaped support structure. Therefore, the stiffness and supporting load of the spokes are mainly determined by the middle connecting part of the V-shaped support structure. Not only are the overall stiffness and load-bearing strength limited, but the overall deformation resistance and stability of the spokes are also poor. The safety, stability and comfort of the non-pneumatic tire prepared in this way will also be affected. Summary of the Invention

[0005] In order to address the deficiencies of the prior art, the present invention provides a non-pneumatic tire spoke, which is assembled by a plurality of spoke unit groups arranged in sequence along the circumferential direction of the tire; wherein the spoke unit group includes a first support member and a second support member nested on the first support member, and a support body is protruded on the ends of the first support member and the second support member; when the spoke is subjected to a load, the two ends of the first support member undergo elastic bending deformation toward the middle, at which time the support body located at the end of the first support member will counteract the second support member nested on the first support member to enhance the overall rigidity and load-bearing strength of the spoke, effectively reducing the degree of deformation of the spoke due to force, thereby effectively improving the overall stability of the spoke. The present invention also provides a non-pneumatic tire assembled using the non-pneumatic tire spoke, which not only effectively improves the overall rigidity and load-bearing strength of the tire and enhances the tire's anti-deformation ability, but also effectively improves the overall stability of the tire, allowing passengers to have a more comfortable and safer riding experience.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical solutions:

[0007] The non-pneumatic tire spokes in the present invention include a plurality of spoke unit groups arranged in sequence along the circumferential direction of the tire; wherein, the spoke unit group includes a first support member and a second support member nested on the first support member; and support bodies are protruding from the ends of the first support member and the second support member, which are used to offset the adjacent support members or spoke unit groups when the spokes are under load, so as to enhance the overall rigidity and load strength of the spokes and improve the overall stability of the spokes.

[0008] As a preferred solution, the support body includes a first pressing portion for pressing against the end of the adjacent support member when bearing a first load, and a second pressing portion for pressing against the middle of the adjacent support member when bearing a second load; wherein the second load is greater than the first load.

[0009] As a preferred solution, the first pressing portion is an arc-shaped protruding structure or a wave-shaped protruding structure protruding from the end of the support member.

[0010] As a preferred solution, the second pressing portion is transitionally connected to the first pressing portion, and the height of the second pressing portion protruding from the support member is lower than that of the first pressing portion.

[0011] As a preferred solution, the support body is a columnar support body with a quadrilateral or pentagonal cross-section.

[0012] As a preferred solution, a groove is provided on a corner of the support body away from the middle of the support member.

[0013] As a preferred solution, the cross-sectional area of ​​the support body on the side adjacent to the tire core is smaller than the cross-sectional area of ​​the support body on the side away from the tire core.

[0014] As a preferred solution, a coupling body is provided in the middle of the first support member and the second support member, which is used to reduce the degree of deformation of the spoke when the spoke is under load.

[0015] As a preferred solution, the cross-section of the combination is a fan-shaped structure, a triangular structure, a quadrilateral structure or a pentagonal structure.

[0016] As a preferred solution, the middle parts of the first support member and the second support member are wrapped with a nose reinforcement part to further enhance the rigidity and bending strength of the spoke as a whole.

[0017] As a preferred embodiment, the cross-sections of the first and second support members are V-shaped, arc-shaped, or bow-shaped. The non-pneumatic tire of the present invention comprises the non-pneumatic tire spokes described above, which are used to provide support and cushioning for the non-pneumatic tire; a hub disposed on one side of the inner circumference of the non-pneumatic tire spokes, which is used to connect the entire non-pneumatic tire to the axle; and a tread connected to one side of the outer circumference of the non-pneumatic tire spokes, which is used to further connect the non-pneumatic tire spokes and protect the non-pneumatic tire spokes.

[0018] In summary, the present invention has at least the following benefits:

[0019] 1. The non-pneumatic tire spoke of the present invention is assembled by a plurality of spoke unit groups arranged in sequence along the circumferential direction of the tire; wherein the spoke unit group includes a first support member and a second support member nested on the first support member, and support bodies are protruding from the ends of the first support member and the second support member. When the spoke is subjected to a load, the support body will offset the adjacent support member or spoke unit group, which can not only effectively enhance the overall rigidity and load-bearing strength of the spoke, but also effectively improve the deformation resistance and stability of the spoke.

[0020] 2. The non-pneumatic tire spokes of the present invention effectively reduce the pulling effect on the bonding surface during compression, greatly reducing the possibility of bonding failure due to the pulling effect on the spoke bonding surface, thereby further effectively improving the stability of the connection between the spokes and the remaining tire components, thereby increasing the life of the tire. 3. The non-pneumatic tire of the present invention, assembled using the above-mentioned non-pneumatic tire spokes with the wheel hub and tread, not only effectively improves the overall rigidity and load-bearing strength of the tire, enhancing the tire's resistance to deformation, but also effectively improves the overall stability of the tire, providing passengers with a more comfortable and safer riding experience.

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0034] Example 1:

[0035] In a preferred embodiment, the non-pneumatic tire spoke 10 comprises a plurality of spoke unit groups sequentially arranged along the circumferential direction of the tire; Figure 1 and 2 The spoke unit group includes a first support member 11 and a second support member 12 nested on the first support member 11, and a support body 111 is protruded on the ends of the first support member 11 and the second support member 12; when the spoke is under load, the two ends of the first support member 11 are elastically bent and deformed toward the middle. At this time, the support body 111 located on the end of the first support member 11 will counteract the second support member 12 nested on the first support member 11 to resist the deformation of the spoke, which can not only effectively reduce the degree of deformation of the spoke due to force, but also effectively enhance the overall rigidity and load strength of the spoke, thereby improving the overall stability of the spoke.

[0036] The first support member 11 and the second support member 12 both include an elastic support body and a fiber-resin composite layer wrapped around the outside of the elastic support body. Since the first support member 11 and the second support member 12 are the main parts of the spoke, they are used to bear most of the load of the spoke and play a major supporting role. Therefore, wrapping the fiber-resin composite layer around the elastic support body that serves as the main body of the first support member 11 and the second support member 12 can effectively enhance the bending stiffness of the elastic support body, so that the first support member 11 and the second support member 12 can bend elastically within a certain range, thereby playing a good supporting and load-bearing role. Preferably, the fiber of the fiber-resin composite layer is one or more of glass fiber, carbon fiber, polyethylene fiber, aramid, aromatic polyester fiber, and high-strength polyethylene fiber; and the resin of the fiber-resin composite layer is one or more of epoxy resin, polyurethane resin, and polyamide resin. Further preferably, the fibers of the fiber-resin composite layer are continuous fibers obtained by twisting glass fibers and aromatic polyester fibers, and the resin of the fiber-resin composite layer is epoxy resin; specifically, the mixed fibers obtained by twisting glass fibers and aromatic polyester fibers are impregnated into epoxy resin, and after sufficient impregnation, they pass through shaping holes and are thermally cured to obtain the final fiber-resin composite material; wherein, the density of the mixed fibers obtained by twisting glass fibers and aromatic polyester fibers is 1200tex, and the shaping holes are used to limit the cross-section of the fiber-resin composite material, and the specific shape and size can be selected according to actual needs and are not limited here; the weight fraction of the fibers in the fiber-resin composite material is 60-80wt%, and the tensile elongation at break of the fiber-resin composite material is 3-6%.

[0037] Furthermore, the cross-sections of the first and second support members 11, 12 are V-shaped, arc-shaped, or bow-shaped. This curved structural design not only effectively ensures the stability of the nested structures between adjacent support members, but also effectively ensures that both ends of the support members deform toward the same side of the support members when subjected to force, further improving the overall stability of the spokes. The specific structures of the first and second support members 11, 12 are not limited and can be designed according to the actual needs of the product, as long as they can provide elastic support for the non-pneumatic tire.

[0038] Please refer to the attached Figure 3 The support body 111 includes a first pressing portion 101 that presses against the end of the adjacent support member when bearing a first load, and a second pressing portion 102 that presses against the middle of the adjacent support member when bearing a second load, wherein the second load is greater than the first load; preferably, the first pressing portion 101 is an arc-shaped protruding structure protruding from the end of the support member, and the second pressing portion 102 is transitionally connected to the first pressing portion 101, and the height of the protruding portion on the support member is lower than the height of the first pressing portion 101. When the spoke bears a load, the higher first pressing portion 101 first presses against the end of the adjacent support member nested thereon (such as the attached Figure 1 As shown in FIG, the wheel spokes 102 and the wheel spokes 103 are provided with support for the tire. Due to the arc-shaped convex structure of the first pressing portion 101, when it contacts the end of the adjacent support member, the force contact point of the two adjacent support members will move along the top of the first pressing portion 101, which can effectively avoid the spoke bonding surface from being subjected to a large tensile stress and prevent the spoke bonding surface from being broken due to the tensile stress. When the spoke continues to bear a greater load, the second pressing portion 102 will continue to contact the middle of the adjacent support member (as shown in FIG. Figure 2 As shown), further support is provided for the tire. Therefore, the support body 111 is convex at different heights, and the higher convexity is designed to be arc-shaped, which can effectively reduce the pulling effect on the bonding surface of the spoke during the compression process, greatly reducing the possibility of bonding failure due to the pulling effect on the bonding surface of the spoke, thereby further effectively improving the stability of the connection between the spoke and the rest of the tire components.

[0039] Furthermore, since the spoke diameter is generally smaller on the side proximal to the tire core and larger on the side distal to the tire core, the cross-sectional area of ​​the support body 111 on the side proximal to the tire core is preferably smaller than the cross-sectional area on the side distal to the tire core. This allows for a coordinated design of the spoke and the tire as a whole, effectively ensuring the overall stability of the spoke. Furthermore, the connecting end surface of the support body 111 to the hub is a concave arc structure, with the arc center and the middle of the support located on either side of the connecting end surface, respectively. The connecting end surface of the support body 111 to the tread is a convex arc structure, with the arc center and the middle of the support located on the same side of the connecting end surface. This allows for a tight bond between the spoke and the outer circumferential surface of the hub, as well as the inner circumferential surface of the tread, further effectively improving the overall stability of the spoke.

[0040] Example 2:

[0041] The non-pneumatic tire spoke 10 in this embodiment is the same as that in embodiment 1, and both include a plurality of spoke unit groups arranged in sequence along the circumferential direction of the tire; Figure 1 and 2 The spoke unit group includes a first support member 11 and a second support member 12 nested on the first support member 11, and a support body 111 is protruded on the ends of the first support member 11 and the second support member 12; the main difference is:

[0042] Please refer to the attached Figure 4The support body 111 includes a first pressing portion 101 that presses against the end of the adjacent support member when bearing a first load, and a second pressing portion 102 that presses against the middle of the adjacent support member when bearing a second load, wherein the second load is greater than the first load; preferably, the first pressing portion 101 is a wave-shaped protruding structure protruding from the end of the support member, and the second pressing portion 102 is transitionally connected to the first pressing portion 101, and the height of the protruding portion on the support member is lower than the height of the first pressing portion 101. When the spoke is under load, the higher first pressing portion 101 first abuts against the end of the adjacent support member nested thereon to provide support for the tire. When it continues to bear a larger load, the second pressing portion 102 continues to abut against the middle of the adjacent support member to provide further support for the tire. Since there is a gap between adjacent protrusions of the wavy protrusion structure when bearing load, the spoke has a certain deformation space during the compression process, which can effectively reduce the pulling effect on the bonding surface and greatly reduce the possibility of bonding failure of the spoke bonding surface due to the pulling effect, thereby further effectively improving the stability of the connection between the spoke and the rest of the tire components.

[0043] Example 3:

[0044] The non-pneumatic tire spoke 10 in this embodiment is the same as that in embodiment 1, and both include a plurality of spoke unit groups arranged in sequence along the circumferential direction of the tire; Figure 1 and 2 The spoke unit group includes a first support member 11 and a second support member 12 nested on the first support member 11, and a support body 111 is protruded on the ends of the first support member 11 and the second support member 12; the main difference is:

[0045] The support body 111 is a quadrilateral structure (see attached Figure 5 as shown) or a pentagonal structure (as shown in the attached Figure 6 The cylindrical support body (shown in FIG. 1 ) can widen the portion where the support member joins the hub and tread, effectively improving the stability of the overall connection between the spokes, the hub, and the tread. Preferably, a groove is formed in a corner of the support body 111 away from the center of the support member. This not only effectively reduces the overall size of the support body 111 but also effectively reduces the pulling effect of the spoke on the bonding surface during compression, significantly reducing the possibility of bonding failure due to the pulling effect, thereby further effectively improving the stability of the connection between the spokes and the remaining components of the tire.

[0046] Example 4:

[0047] The non-pneumatic tire spoke 10 in this embodiment is further designed with respect to the first support member 11 and the second support member 12 on the basis of any one of the embodiments 1-3. The design is as follows:

[0048] Please see the attached Figure 1-6 , a coupling 112 is provided in the middle of the first support member 11 and the second support member 12. When the spoke is under load, the two ends of the first support member 11 and the second support member 12 are elastically bent and deformed toward the middle. When the support member is deformed to a certain extent, the middle part tends to bear a larger load. Therefore, adding a coupling 112 in the middle of the support member can effectively improve the structural rigidity and strength of the support member, thereby reducing the degree of deformation of the spoke due to force, and further effectively improving the overall stability of the spoke. The cross section of the coupling 112 is a fan-shaped structure (such as the one attached) with a thickness near the bend of the support member greater than the thickness away from the bend of the support member. Figure 7 (a) in the figure), triangular structure (as shown in the attached figure) Figure 7 (b)), quadrilateral structure (as shown in the attached Figure 7 (c)) or a pentagonal structure (as shown in the attached Figure 7 (d) in the figure) can make the non-pneumatic tire spoke 10 adapt to both compression and tension conditions at the same time; preferably, the middle part of the combination 112 is designed to bulge toward one side of the middle part of the support member. When the non-pneumatic tire spoke 10 is pre-compressed and loaded into the tire, the thicker design of the middle part of the combination 112 can provide greater compression force during compression. When the non-pneumatic tire spoke 10 is pre-stretched and loaded into the tire, the bulging design of the middle part of the combination 112 can withstand greater tensile strain than the concave design of the middle part, thereby avoiding large deformation of the side of the support member during the stretching process.

[0049] Taking into account the stability and comfort of the tire during driving, the combination 112 and the support body 111 are selected to be polyurethane materials, rubber materials, polyamide resin materials or polyester materials with a modulus lower than that of the first support member 11 and the second support member 12; preferably, the tensile modulus of the combination 112 and the support body 111 is 4-20MPa.

[0050] Example 5:

[0051] The non-pneumatic tire spoke 10 in this embodiment is further designed with respect to the first support member 11 and the second support member 12 on the basis of any one of the embodiments 1-4. The design is as follows:

[0052] Please see the attached Figure 1-6The middle portions of the first support member 11 and the second support member 12 are wrapped with a nose reinforcement membrane 113. When the spokes bear a load, the provision of the nose reinforcement membrane 113 can further effectively increase the tensile strength of the support members as a whole, thereby effectively improving the bearing capacity of the spokes as a whole, further reducing the degree of deformation of the spokes due to the force, and further effectively improving the stability of the spokes as a whole. Preferably, the nose reinforcement membrane 113 includes an elastic membrane wrapped around the middle portion of the support members, and a cord threaded through the elastic membrane, wherein the cord is one or more of polyester fiber, rayon, aromatic polyamide, nylon, and cotton; the length, number, diameter, arrangement, and arrangement density of the cord can be adjusted according to the different bearing performance of the spokes; similarly, the number of cord layers can also be designed to be one or more layers according to the different requirements of the spokes, and when the number of cord layers is more than one, at least one layer must be positioned in the radial direction of the tire.

[0053] Example 6:

[0054] Please see the attached Figure 8 The non-pneumatic tire in this embodiment includes any non-pneumatic tire spoke 10 in Examples 1-5, a hub 20 provided on one side of the inner circumferential surface of the non-pneumatic tire spoke 10, and a tread 30 connected to one side of the outer circumferential surface of the non-pneumatic tire spoke 10; wherein the non-pneumatic tire spoke 10 is used to provide support and cushioning for the non-pneumatic tire, the hub 20 is used to achieve the connection between the non-pneumatic tire as a whole and the axle, and the tread 30 is used to achieve further connection of the non-pneumatic tire spoke 10 and protect the non-pneumatic tire spoke 10.

[0055] The non-pneumatic tire in this embodiment is assembled using any of the non-pneumatic tire spokes 10 in Examples 1-5, the hub 20, and the tread 30. It can not only effectively improve the overall rigidity and load-bearing strength of the tire and enhance the tire's anti-deformation ability, but also effectively improve the overall stability of the tire, allowing passengers to have a more comfortable and safer riding experience.

[0056] As can be seen from the technical solutions of the above embodiments, the present invention provides a non-pneumatic tire spoke that not only exhibits excellent rigidity and load-bearing strength, but also exhibits excellent deformation resistance and stability. The present invention also provides a non-pneumatic tire assembled using the non-pneumatic tire spoke. This non-pneumatic tire not only effectively improves the overall rigidity and load-bearing strength of the tire, enhancing its deformation resistance, but also effectively improves its overall stability, providing passengers with a more comfortable and safer riding experience.
