Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and in particular to a hub and a wheel with a non-pneumatic tire. Background Art

[0002] In the relevant technical field, non-pneumatic tires have become a commonly used tire type. Conventional non-pneumatic tires usually adopt the method of directly integrally molding the spokes or fixing them on the wheel hub by bonding.

[0003] However, this connection method has obvious defects, mainly manifested in the instability of the connection and the problem of detachment failure between the spoke and the hub. Utility Model Content

[0004] The embodiments of the present application provide a hub and wheel for a non-pneumatic tire, which can ensure that the connection between the hub and the spokes of the non-pneumatic tire is not only firm and reliable, but also can withstand large loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0005] In a first aspect, an embodiment of the present application provides a non-pneumatic tire hub for mounting a spoke, wherein at least one limiting protrusion is provided on the inner circumference of the spoke, and the non-pneumatic tire hub includes:

[0006] The first split body has at least one first limiting groove provided on its outer circumference, and the limiting protrusion can be limited in the first limiting groove;

[0007] a second split body detachably connected to the first split body, wherein at least one second limiting groove is provided on an outer circumference of the second split body, and the other portion of the limiting protrusion can be limited in the second limiting groove;

[0008] The first limiting groove and the second limiting groove correspond to each other one by one and can be spliced to form a limiting cavity, and the limiting protrusion is accommodated in the limiting cavity.

[0009] The wheel hub of a non-pneumatic tire can be used to mount spokes. In this application, at least one limiting protrusion is provided on the inner circumference of the spoke. The wheel hub can cooperate with the limiting protrusion. The wheel hub of a non-pneumatic tire can specifically include a first split body and a second split body.

[0010] At least one first retaining groove is provided on the outer circumference of the first sub-body. The first retaining groove is designed to accommodate and retain a portion of the spoke's retaining protrusion. This allows the corresponding portion of the retaining protrusion to be retained within the first retaining groove, ensuring a stable connection between the spoke and the first sub-body in the hub.

[0011] At the same time, the second body is detachably connected to the first body. To further enhance the stability and reliability of the connection, at least one second retaining groove is also provided on the outer circumference of the second body. The second retaining groove functions similarly to the first retaining groove, accommodating and retaining the other portion of the retaining protrusion on the spoke. In this way, the other portion of the retaining protrusion can be retained within the second retaining groove, further ensuring a tight connection between the spoke and the hub.

[0012] It's worth noting that the first and second limiting grooves are designed to correspond one-to-one, allowing them to be joined together to form a complete limiting cavity. When the limiting protrusions on the spokes are fully accommodated within this limiting cavity, the stability of the entire structure is greatly enhanced. The connection between the hub and spokes of the non-pneumatic tire in this application is not only secure and reliable, but can also withstand significant loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0013] In some examples, a nested structure is provided in the middle of the first split body, and a socket hole is provided in the middle of the second split body. After the first split body is connected to the second split body, the nested structure is embedded in the socket hole.

[0014] A nested structure is designed and provided in the middle position of the first split body mentioned above in the present application. The nested structure can be in any form, such as a protrusion, a sleeve, a groove, a slot or other structures that can realize the nesting function. At the same time, a corresponding socket hole is also designed and provided in the middle position of the second split body. This socket hole can be a hole, a groove or other structure that can match the nested structure and realize the socket function. When the first split body is connected to the second split body, the nested structure of the first split body will be embedded in the socket hole of the second split body. This design not only ensures a close connection between the two split bodies, but also may provide additional mechanical strength and stability, thereby making the overall structure more solid and reliable.

[0015] In some examples, the first split body and the second split body are detachably connected via a plurality of fixing members, a plurality of first assembly holes are provided on the first split body, and a plurality of second assembly holes are provided on the second split body, and the fixing members can be simultaneously passed through the first assembly holes and the second assembly holes and fixedly connected the second split body and the second split body.

[0016] The detachable connection between the first component and the second component is achieved through multiple fixing parts. Specifically, multiple first assembly holes are designed on the structure of the first component, and the multiple first assembly holes can be evenly distributed to facilitate subsequent assembly operations. Similarly, multiple second assembly holes are also provided at the corresponding positions of the second component, and the multiple second assembly holes correspond to the multiple first assembly holes on the first component.

[0017] Through the above method, the fixing parts can easily pass through the first assembly holes and the second assembly holes to achieve the fixed connection between the first component and the second component. These fixing parts generally include bolts, screws or other similar fasteners, which can ensure that the two components are closely combined together, while maintaining the detachable nature of the connection for future maintenance or replacement operations. The above settings not only improve the convenience of assembly, but also ensure the stability and reliability of the structure.

[0018] In some examples, at least one of the first assembly holes is provided between two adjacent first limiting grooves on the first component, and at least one of the second assembly holes is provided between two adjacent second limiting grooves on the second component.

[0019] In the structural design of the first component, one or more first assembly holes are specifically provided between two adjacent first limiting grooves. The purpose of the first assembly holes is to facilitate assembly and fixation, ensuring that the first component and the second component can be accurately connected together. Similarly, in the design of the second component, at least one second assembly hole is also provided between two adjacent second limiting grooves. The functions of these second assembly holes are similar to those of the first assembly holes, aiming to provide a reliable connection point so that the second component can be firmly combined with the first component. Through the above design, the stability and accuracy of the entire structure can be ensured, and at the same time, it is also convenient for operations during production and assembly.

[0020] In some examples, the limiting protrusion includes a connecting part and a limiting part. The connecting part is connected to the inner peripheral surface of the spoke, and one side of the connecting part背离 the inner peripheral surface of the spoke is connected to the limiting part, and the size of the connecting part is smaller than the size of the limiting part.

[0021] The above limiting protrusion can include two main parts: a connecting part and a limiting part. The function of the connecting part is to connect and fix to the inner peripheral surface of the spoke to ensure that the limiting protrusion can be firmly installed on the spoke. On the other side of the connecting part, that is, the side背离 the inner peripheral surface of the spoke, it is connected to the limiting part. The main function of the limiting part is to limit the relative displacement between the spoke and the hub and prevent excessive offset between the spoke and the hub.

[0022] In some examples, the limiting protrusion includes one of a "T" - shaped protrusion, an "L" - shaped protrusion, a "Z" - shaped protrusion, a "艹" - shaped protrusion, a "φ" - shaped protrusion, and a燕尾 protrusion.

[0023] The above-mentioned limiting protrusions can adopt various different shapes, including but not limited to one or more of "T"-shaped protrusions, "L"-shaped protrusions, "Z"-shaped protrusions, "艹"-shaped protrusions, "φ"-shaped protrusions, and燕尾protrusions. The setting methods of these limiting protrusions can all provide a reliable mechanical locking mechanism to ensure a stable connection between the spoke and the hub.

[0024] In some examples, at least one weight-reducing hole is provided on the first split body and / or the second split body.

[0025] The setting of these weight-reducing holes can reduce the weight of the overall structure and improve its performance and efficiency. By arranging weight-reducing holes on these split bodies, the use of materials can be effectively reduced while maintaining the strength and stability of the structure.

[0026] In some examples, a first limiting edge is provided on one side of the first split body facing away from the second split body, and a second limiting edge is provided on one side of the second split body facing away from the first split body;

[0027] When the first split body and the second split body are connected, the outer peripheral surfaces are spliced to form an assembly surface. Both the first limiting edge and the second limiting edge protrude from the assembly surface. The first limiting edge, the second limiting edge, and the assembly surface cooperate to form an assembly groove, and the inner ring of the spoke is embedded in the assembly groove.

[0028] In the above structure, a first limiting edge is provided on the outer edge part of the first split body, and the first limiting edge is located on the side where the first split body faces away from the second split body. Similarly, a second limiting edge is provided on the outer edge part of the second split body, and the second limiting edge is located on the side where the second split body faces away from the first split body. When the first split body and the second split body are connected, the outer peripheral surfaces of the first split body and the second split body are spliced together to form a complete assembly surface. In this spliced state, both the first limiting edge and the second limiting edge protrude above the assembly surface. These two limiting edges and the assembly surface cooperate to form an assembly groove. The function of the assembly groove is to accommodate the inner ring part of the spoke, so that the spoke can be embedded in this assembly groove, thereby realizing the stable connection of the first split body, the second split body and the spoke.

[0029] In some examples, a guiding structure is provided on one side of the first limiting groove close to the limiting protrusion; and / or,

[0030] A guiding structure is provided on one side of the second limiting groove close to the limiting protrusion; and / or,

[0031] A guiding structure is provided on one side of the limiting protrusion close to the first limiting groove; and / or,

[0032] A guide structure is provided on one side of the limiting protrusion close to the second limiting groove.

[0033] The above structure illustrates multiple implementations of guide structures, and at least one of these implementations can be configured as needed. Specifically, a guide structure can be provided on the edge of the first retaining groove, i.e., on the side closest to the retaining projection. This guide structure helps ensure smooth and accurate positioning and movement of related components during operation. The same design philosophy is also applied to the second retaining groove, with a similar guide structure provided on the side of the second retaining groove closest to the retaining projection. This design not only improves overall efficiency but also enhances the stability and reliability of the system. Furthermore, to ensure that the retaining projection can better perform its function during use, a guide structure is also provided on the side of the retaining projection closest to the first retaining groove. This design enables more precise positioning and guidance of the retaining projection when used in conjunction with the first retaining groove. Similarly, a guide structure is also provided on the side of the retaining projection closest to the second retaining groove to ensure the same effect when used in conjunction with the second retaining groove. By providing these guide structures, the operational accuracy and reliability of the entire system are significantly improved.

[0034] In a second aspect, an embodiment of the present application provides a wheel comprising a hub, spokes and tread of a non-pneumatic tire as described above, wherein the hub comprises a first split and a second split that are detachably connected; a limiting protrusion is provided on the inner circumference of the spoke, and the limiting protrusion is limited in the limiting cavity formed by the cooperation of the first split and the second split; and the tread is installed on the outer circumference of the spoke.

[0035] The wheel with the above-mentioned hub of the present application can make the connection between the hub and the spokes of the non-pneumatic tire not only firm and reliable, but also able to withstand large loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0036] Specifically, at least one first retaining groove is provided on the outer circumference of the first sub-body. The first retaining groove is designed to accommodate and retain a portion of the retaining protrusion on the spoke. This allows the corresponding portion of the retaining protrusion to be retained within the first retaining groove, thereby ensuring a stable connection between the spoke and the first sub-body in the hub.

[0037] At the same time, the second body is detachably connected to the first body. To further enhance the stability and reliability of the connection, at least one second retaining groove is also provided on the outer circumference of the second body. The second retaining groove functions similarly to the first retaining groove, accommodating and retaining the other portion of the retaining protrusion on the spoke. In this way, the other portion of the retaining protrusion can be retained within the second retaining groove, further ensuring a tight connection between the spoke and the hub.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0049] To solve the above technical problems, please refer to Figure 1-Figure 7 As shown, the first aspect of the present application proposes a non-pneumatic tire hub 100, which can ensure that the connection between the non-pneumatic tire hub 100 and the spokes 200 is not only firm and reliable, but also can withstand greater loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0050] Reference Figure 1-Figure 3 As shown, in some examples, the non-pneumatic tire hub 100 is used to install the spoke 200 , and at least one limiting protrusion 210 is provided on the inner circumference of the spoke 200 . The non-pneumatic tire hub 100 includes a first split body 110 and a second split body 120 .

[0051] At least one first limiting groove 111 is provided on the outer circumference of the first split body 110, and a portion of the limiting protrusion 210 can be limited to the first limiting groove 111;

[0052] The second split body 120 is detachably connected to the first split body 110 . The outer circumference of the second split body 120 is provided with at least one second limiting groove 121 . The other part of the limiting protrusion 210 can be limited in the second limiting groove 121 .

[0053] The first limiting groove 111 and the second limiting groove 121 correspond to each other one by one and can be spliced to form a limiting cavity 130 , and the limiting protrusion 210 is accommodated in the limiting cavity 130 .

[0054] The non-pneumatic tire hub 100 can be used to mount the spokes 200. In this application, the inner circumference of the spokes 200 is provided with at least one limiting protrusion 210. The hub 100 can cooperate with the limiting protrusion 210. The non-pneumatic tire hub 100 can specifically include a first sub-body 110 and a second sub-body 120.

[0055] At least one first retaining groove 111 is provided on the outer circumference of the first split body 110. The first retaining groove 111 is designed to accommodate and retain a portion of the retaining protrusion 210 on the spoke 200. This allows the corresponding portion of the retaining protrusion 210 to be retained within the first retaining groove 111, thereby ensuring a stable connection between the spoke 200 and the first split body 110 in the hub 100.

[0056] At the same time, the second body 120 is detachably connected to the first body 110. To further enhance the stability and reliability of the connection, at least one second retaining groove 121 is also provided on the outer circumference of the second body 120. The second retaining groove 121 functions similarly to the first retaining groove 111, accommodating and retaining the other portion of the retaining protrusion 210 on the spoke 200. This retaining groove 121 retains the other portion of the retaining protrusion 210, further ensuring a tight connection between the spoke 200 and the hub 100.

[0057] It's worth noting that the first limiting groove 111 and the second limiting groove 121 are designed to correspond one-to-one. They can be joined together to form a complete limiting cavity 130. When the limiting protrusions 210 on the spokes 200 are fully accommodated within this limiting cavity 130, the stability of the entire structure is greatly enhanced. The connection between the hub 100 and the spokes 200 of the non-pneumatic tire in this application is not only secure and reliable, but can also withstand significant loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0058] It should be noted that the limiting protrusion 210 can be configured as two parts, including a first limiting sub-body 210a and a second limiting sub-body 210b that are spliced together or integrally configured. The first limiting sub-body 210a is the portion of the limiting protrusion 210 that is limited to the first limiting groove 111, and the second limiting sub-body 210b is the portion of the limiting protrusion 210 that is limited to the second limiting groove 121. The shapes and sizes of the first limiting sub-body 210a and the second limiting sub-body 210b can be the same or different, and the corresponding first limiting grooves 111 and second limiting grooves 121 are also adaptively adjusted.

[0059] In the present application, at least a portion of the first limiting sub-body 210a can be configured as a wedge shape (with a gradually decreasing size in the relative width direction), and the corresponding first limiting groove 111 can also be configured as a wedge groove. The first limiting sub-body 210a can also be configured as a wedge shape as needed.

[0060] The spoke 200 in the present application may include an inner ring 220, a spoke unit 230 and an outer ring 240. The above-mentioned limiting protrusion 210 is arranged on the inner circumference of the inner ring 220, and the above-mentioned tread 300 is installed on the outer circumference of the outer ring 240. There are multiple spoke units 230, and the multiple spoke units 230 are all located between the inner ring 220 and the outer ring 240.

[0061] The tire of the present application may be a non-pneumatic tire, specifically a bottom-load-bearing tire or a top-load-bearing tire.

[0062] Specifically, the tire's load-bearing mode can be set to two bottom load-bearing modes and a top load-bearing mode. Traditional pneumatic tires and solid tires both adopt the bottom load-bearing mode, that is, the load is transferred to the ground through the elastomer on the sidewall or the bottom; the tire load-bearing principle of the top load-bearing mode is that the tire tread 300 has a support ring (rigid ring), the spokes are flexible, and the flexible spokes are circumferentially distributed in the support ring. The load is suspended on the support ring through the flexible spokes distributed on the top, and the flexible spokes at the bottom only play a role of easy bending and deformation, and do not play a major supporting and load-bearing role.

[0063] Specifically, the non-pneumatic tire in the present application can be configured as a top-load bearing tire, having a rigid outer ring 240 (embedded within the tread 300). During driving, the tire load is primarily borne by the rigid outer ring 240, and the spokes 200 include spokes with traction capabilities, referred to as spoke units 230. When the tire is subjected to pressure, the spoke units 230 located relatively above will be stretched and generate tensile force, while the spoke units 230 located relatively below will be compressed. Because the spokes 200 themselves do not have any supporting force, the force applied to the hub 100 will be transmitted to the upper portion of the outer ring 240 through the upper spoke units 230. The rigidity of the outer ring 240 then transmits the force to the lower portion of the outer ring 240 where it contacts the ground.

[0064] In some examples, a nesting structure 112 is provided in the middle of the first split body 110 , and a socket hole 122 is provided in the middle of the second split body 120 . After the first split body 110 and the second split body 120 are connected, the nesting structure 112 is embedded in the socket hole 122 .

[0065] In the present application, a nested structure 112 is designed and provided at the middle position of the first body 110. The nested structure 112 can be in any form, such as a protrusion, a sleeve, a groove, a slot or other structures that can realize the nesting function. At the same time, a corresponding socket hole 122 is also designed and provided at the middle position of the second body 120. This socket hole 122 can be a hole, a groove or other structure that can match the nested structure 112 and realize the socket function. When the first body 110 is connected to the second body 120, the nested structure 112 of the first body 110 will be embedded in the socket hole 122 of the second body 120. This design not only ensures a close connection between the two bodies, but also may provide additional mechanical strength and stability, thereby making the overall structure more solid and reliable.

[0066] The nested structure 112 in the present application may specifically be a sleeve structure, and the outer peripheral surface of the sleeve structure may be adapted to the sleeve hole 122 to form a sleeve limit.

[0067] Reference Figure 1-Figure 3 As shown, in some examples, the first split 110 and the second split 120 are detachably connected through multiple fixing parts, a plurality of first assembly holes 113 are provided on the first split 110, and a plurality of second assembly holes 123 are provided on the second split 120. The fixing parts can be simultaneously passed through the first assembly holes 113 and the second assembly holes 123 and fixedly connected the second split 120 and the second split 120.

[0068] The first and second sub-body 110 and 120 are detachably connected via multiple fasteners. Specifically, the first sub-body 110 is designed with multiple first assembly holes 113, which are evenly distributed to facilitate subsequent assembly. Similarly, the second sub-body 120 is also provided with multiple second assembly holes 123 at corresponding locations, corresponding to the multiple first assembly holes 113 on the first sub-body 110.

[0069] Through this method, the fixings can easily pass through the first assembly hole 113 and the second assembly hole 123, thereby achieving a fixed connection between the first sub-body 110 and the second sub-body 120. These fixings typically include bolts, screws, or other similar fasteners, which ensure that the two sub-bodies are tightly connected together while maintaining a removable connection to facilitate future maintenance or replacement operations. This arrangement not only improves assembly convenience but also ensures structural stability and reliability.

[0070] In some examples, at least one first assembly hole 113 is provided between two adjacent first limiting grooves 111 on the first split body 110 , and at least one second assembly hole 123 is provided between two adjacent second limiting grooves 121 on the second split body 120 .

[0071] In the structural design of the first body 110, one or more first assembly holes 113 are deliberately provided between two adjacent first limiting grooves 111. The purpose of the first assembly holes 113 is to facilitate assembly and fixation, and to ensure that the first body 110 and the second body 120 can be accurately connected together. Similarly, in the design of the second body 120, at least one second assembly hole 123 is also provided between two adjacent second limiting grooves 121. The function of these second assembly holes 123 is similar to that of the first assembly holes 113, and is intended to provide a reliable connection point so that the second body 120 can be firmly combined with the first body 110. Through the above design, the stability and accuracy of the entire structure can be ensured, while also facilitating operation during production and assembly.

[0072] Reference Figure 1-Figure 3 As shown, in some examples, the limiting protrusion 210 includes a connecting portion 211 and a limiting portion 212, the connecting portion 211 is connected to the inner circumference of the spoke 200, and the side of the connecting portion 211 facing away from the inner circumference of the spoke 200 is connected to the limiting portion 212, and the size of the connecting portion 211 is smaller than the size of the limiting portion 212.

[0073] The aforementioned limiting protrusion 210 can include two main parts: a connecting portion 211 and a limiting portion 212. The connecting portion 211 connects and secures to the inner circumference of the spoke 200, ensuring that the limiting protrusion 210 is securely mounted on the spoke 200. The other side of the connecting portion 211, facing away from the inner circumference of the spoke 200, is connected to the limiting portion 212. The limiting portion 212 primarily limits relative displacement between the spoke 200 and the hub 100, preventing excessive displacement between the spokes 200 and the hub 100. In these examples, the connecting portion 211 is designed to be slightly smaller than the limiting portion 212 to ensure that the limiting portion 212 can effectively perform its limiting function while maintaining the compactness and stability of the overall structure. The limiting protrusion 210 effectively limits the relative position of the spoke 200 by mating with the hub 100 without affecting the normal function of the spoke 200, thereby improving the reliability and safety of the overall structure.

[0074] Reference Figure 1-Figure 3As shown, in some examples, the limiting protrusion 210 includes one of a "T" - shaped protrusion, an "L" - shaped protrusion, a "Z" - shaped protrusion, a "艹" - shaped protrusion, a "φ" - shaped protrusion, and a燕尾 protrusion. The shape of the limiting cavity 130 is adapted to the shape of the limiting protrusion 210. Such a setting can make the connection between the first split body 110 and the second split body 120 more stable and reliable.

[0075] The above - mentioned limiting protrusion 210 can adopt various different shapes, including but not limited to one or more of a "T" - shaped protrusion, an "L" - shaped protrusion, a "Z" - shaped protrusion, a "艹" - shaped protrusion, a "φ" - shaped protrusion, and a燕尾 protrusion. The setting methods of these limiting protrusions 210 can all provide a reliable mechanical locking mechanism to ensure the stable connection between the spoke 200 and the hub 100.

[0076] The shape of the limiting cavity 130 matches the shape of the corresponding limiting protrusion 210, forming a complementary structure. This design enables the first split body 110 and the second split body 120 to fit tightly when connected, thereby greatly enhancing the stability and reliability of the connection. Through this precise fit, the relative movement or misalignment between the split bodies can be effectively prevented, ensuring the stability and durability of the entire device or structure during use.

[0077] Refer to Figure 1-Figure 3 As shown, in some examples, at least one weight - reducing hole 115 is provided on the first split body 110 and / or the second split body 120.

[0078] On the surface or structure of the above - mentioned first split body 110 and / or the second split body 120 of the present application, at least one weight - reducing hole 115 is designed and configured. The setting of these weight - reducing holes 115 can reduce the weight of the overall structure and improve its performance and efficiency. By arranging the weight - reducing holes 115 on these split bodies, the use of materials can be effectively reduced while maintaining the strength and stability of the structure. This design method can achieve the purpose of optimizing the performance of the hub 100 and reducing costs.

[0079] Refer to Figure 4-Figure 7 As shown, in some examples, a first limiting edge 114 is provided on one side of the first split body 110 facing away from the second split body 120, and a second limiting edge 124 is provided on one side of the second split body 120 facing away from the first split body 110;

[0080] When the first split body 110 and the second split body 120 are connected, their outer peripheral surfaces are spliced to form an assembly surface 140. Both the first limiting edge 114 and the second limiting edge 124 protrude from the assembly surface 140. The first limiting edge 114, the second limiting edge 124, and the assembly surface 140 cooperate to form an assembly groove 150, and the inner ring 220 of the spoke 200 is embedded in the assembly groove 150.

[0081] In the above structure, a first limiting rib 114 is provided on the outer edge of the first sub-body 110. The first limiting rib 114 is located on the side of the first sub-body 110 that faces away from the second sub-body 120. Similarly, a second limiting rib 124 is provided on the outer edge of the second sub-body 120. The second limiting rib 124 is located on the side of the second sub-body 120 that faces away from the first sub-body 110. When the first sub-body 110 and the second sub-body 120 are connected, the outer peripheral surfaces of the first sub-body 110 and the second sub-body 120 are spliced together to form a complete assembly surface 140. In this spliced state, the first limiting rib 114 and the second limiting rib 124 both protrude above the assembly surface 140. These two limiting ribs cooperate with the assembly surface 140 to form an assembly groove 150. The function of the assembly groove 150 is to accommodate the inner ring 220 portion of the spoke 200 so that the spoke 200 can be embedded in the assembly groove 150 , thereby achieving a stable connection between the first and second sub-bodies 110 and 120 and the spoke 200 .

[0082] In some examples, a guide structure is provided on one side of the first limiting groove 111 close to the limiting protrusion 210; and / or,

[0083] A guide structure is provided on one side of the second limiting groove 121 close to the limiting protrusion 210; and / or,

[0084] A guide structure is provided on one side of the limiting protrusion 210 close to the first limiting groove 111; and / or,

[0085] A guide structure is provided on one side of the limiting protrusion 210 close to the second limiting groove 121 .

[0086] The above structure shows multiple embodiments of the guide structure, and at least one of the above embodiments can be set as needed. Specifically, the edge portion of the first limiting groove 111, that is, the side close to the limiting protrusion 210, can be provided with a guide structure. Such a guide structure helps to ensure that the relevant components can be positioned and moved smoothly and accurately during operation. In addition, the same design concept is also applied to the second limiting groove 121, that is, a similar guide structure is also provided on the side of the second limiting groove 121 close to the limiting protrusion 210. This design not only improves the overall efficiency of use, but also enhances the stability and reliability of the system. Furthermore, in order to ensure that the limiting protrusion 210 can better perform its function during use, the side of the limiting protrusion 210 close to the first limiting groove 111 is also equipped with a guide structure. This design enables the limiting protrusion 210 to be positioned and guided more accurately when used in conjunction with the first limiting groove 111. Similarly, a guide structure is also provided on the side of the limiting protrusion 210 close to the second limiting groove 121 to ensure that the same effect can be achieved when used in conjunction with the second limiting groove 121. By providing these guide structures, the operating accuracy and reliability of the entire system are significantly improved.

[0087] In the second aspect, an embodiment of the present application provides a wheel, including a hub 100, spokes 200 and a tread 300 of the non-pneumatic tire as described above, the hub 100 including a first split 110 and a second split 120 that are detachably connected; a limiting protrusion 210 is provided on the inner circumference of the spoke 200, and the limiting protrusion 210 is limited in a limiting cavity 130 formed by the first split 110 and the second split 120; the tread 300 is installed on the outer circumference of the spoke 200.

[0088] The wheel having the above-mentioned hub 100 of the present application can make the connection between the hub 100 and the spokes 200 of the non-pneumatic tire not only firm and reliable, but also able to withstand large loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0089] Specifically, at least one first retaining groove 111 is provided on the outer circumference of the first split body 110. The first retaining groove 111 is designed to accommodate and retain a portion of the retaining protrusion 210 on the spoke 200. This allows the corresponding portion of the retaining protrusion 210 to be retained within the first retaining groove 111, thereby ensuring a stable connection between the spoke 200 and the first split body 110 in the hub 100.

[0090] At the same time, the second body 120 is detachably connected to the first body 110. To further enhance the stability and reliability of the connection, at least one second retaining groove 121 is also provided on the outer circumference of the second body 120. The second retaining groove 121 functions similarly to the first retaining groove 111, accommodating and retaining the other portion of the retaining protrusion 210 on the spoke 200. This retaining groove 121 retains the other portion of the retaining protrusion 210, further ensuring a tight connection between the spoke 200 and the hub 100.

[0091] It's worth noting that the first limiting groove 111 and the second limiting groove 121 are designed to correspond one-to-one. They can be joined together to form a complete limiting cavity 130. When the limiting protrusions 210 on the spokes 200 are fully accommodated within this limiting cavity 130, the stability of the entire structure is greatly enhanced. The connection between the hub 100 and the spokes 200 of the non-pneumatic tire in this application is not only secure and reliable, but can also withstand significant loads and impacts during actual use, thereby ensuring the overall performance and safety of the tire.

[0092] The wheel of the present application is a non-pneumatic tire, specifically comprising a hub 100, spokes 200 and a tread 300. The hub 100 is the core of the entire wheel and is composed of two detachably connected parts, namely a first part 110 and a second part 120.

[0093] The spokes 200 are a key structure connecting the hub 100 and the tread 300. They not only transmit force but also ensure the stability and safety of the wheel. To further enhance performance, stopper protrusions 210 are designed on the inner circumference of the spokes 200. These stopper protrusions 210 function to position the first and second sub-sections 110, 120 within the stopper cavity 130 formed by the first and second sub-sections, ensuring that the two sub-sections do not move relative to each other during use, maintaining the stability and reliability of the wheel.

[0094] The tread 300, the part of the wheel that contacts the ground, is mounted on the outer periphery of the spokes 200. The design of the tread 300 takes into account multiple factors, including grip, wear resistance, and shock absorption, to ensure a superior driving experience in all road conditions. This meticulously designed structure not only ensures excellent performance but also high durability and reliability, providing users with a stable and safe driving experience.
