Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and in particular to a wheel hub reconstruction device and a wheel hub assembly. Background Art

[0002] The hub structure of the non-pneumatic tires widely used in the market still follows the traditional pneumatic tire hub design. This design results in that a special glue must be used to fill the groove part on the pneumatic tire hub when assembling the non-pneumatic tire.

[0003] However, this assembly method has obvious disadvantages. First, it will significantly increase the overall weight of the tire because the glue itself has a certain mass. Second, this assembly method will significantly increase the production cost of the tire because the use of glue and related processes will increase material and labor costs. In addition, the use of glue may also affect the overall performance and durability of the tire. Summary of the invention

[0004] The embodiment of the present application provides a wheel hub modification device and a wheel hub assembly, which can transform a traditional pneumatic tire wheel hub into a modern non-pneumatic tire wheel hub, and can reduce glue and labor costs, resulting in lower costs and higher overall performance of the non-pneumatic tire after modification.

[0005] In a first aspect, an embodiment of the present application provides a wheel hub modification device for modifying a pneumatic tire wheel hub into a non-pneumatic tire wheel hub, wherein an outer peripheral side of the pneumatic tire wheel hub is provided with an assembly groove, and the wheel hub modification device can modify and fill the assembly groove, and the wheel hub modification device comprises:

[0006] The device body has a hub mounting portion, and the pneumatic tire hub is mounted on the hub mounting portion;

[0007] A driving member, mounted on the device body, the pneumatic tire hub being connectable to the driving member and rotating with the driving member;

[0008] A conveying assembly installed on the equipment body, the conveying assembly is arranged on one side of the pneumatic tire hub, and the conveying assembly can convey the filling plate and place the filling plate part in the assembly groove;

[0009] A fixing assembly, mounted on the equipment body, the fixing assembly being capable of fixing the filling plate to the pneumatic tire hub;

[0010] Wherein, after the driving member drives the pneumatic tire to rotate one circle, the filling plate surrounds the pneumatic tire wheel hub one circle and completely blocks the assembly groove, and after the filling plate blocks the assembly groove, the spoke assembly surface of the non-pneumatic tire is formed.

[0011] Wheel modification equipment is used to transform traditional pneumatic tire wheels into modern non-pneumatic tire wheels. This modification process involves adjusting and modifying the structure of the original pneumatic tire wheel so that the modified wheel can adapt to the use requirements of non-pneumatic tires. In this process, the outer peripheral side of the pneumatic tire wheel itself is usually provided with a mounting groove specifically for mounting the pneumatic tread. The mounting groove needs to be blocked during the modification process to reduce the waste of resources due to filling the mounting groove.

[0012] The main body of the device has a hub mounting portion on which the pneumatic tire hub can be accurately mounted and fixed. The design of the main body of the device ensures the stability and accuracy of the hub during the transformation process.

[0013] The drive is a part of the wheel hub modification equipment. The drive is installed on the main body of the equipment and is directly or indirectly connected to the pneumatic tire hub. The function of the drive is to drive the pneumatic tire hub to rotate. During the modification process, the drive will drive the pneumatic tire hub to rotate one circle to ensure the smooth progress of the subsequent steps.

[0014] The conveyor assembly is a key part of the wheel hub reconstruction equipment responsible for conveying the filling material. The conveyor assembly is also installed on the main body of the equipment and is set on one side of the pneumatic tire hub. The function of the conveyor assembly is to accurately convey the filling plate to the specified position and ensure that the filling plate is partially in the assembly groove. The design of the conveyor assembly must ensure the precise placement of the filling plate to ensure that the modified wheel hub can achieve the expected performance and strength.

[0015] The fixing assembly is the part of the wheel hub rebuilding machine that is used to fix the filler plate. The fixing assembly is also installed on the main body of the machine and can fix the filler plate to the pneumatic tire hub. The design of the fixing assembly must be strong and reliable enough to ensure that the filler plate will not move or fall off during the rebuilding process.

[0016] During the operation of the wheel hub modification equipment, the conveying component conveys the filling plate into the assembly groove, and the fixing component fixes the filling plate to the pneumatic tire hub. At this time, the driving part drives the pneumatic tire hub to rotate, and the rotation makes the filling plate bend and fix in the assembly groove until the hub rotates one circle to completely seal the assembly groove. The sealed assembly groove cooperates with the filling plate to form the spoke assembly surface of the non-pneumatic tire.

[0017] After this series of steps, the filling plate surrounds the pneumatic tire hub and completely blocks the assembly groove. Finally, the filling plate blocks the assembly groove to form the spoke assembly surface of the non-pneumatic tire, thus completing the entire hub transformation process. In this way, the hub originally used for pneumatic tires is successfully transformed into a hub suitable for non-pneumatic tires, greatly improving the durability and safety of the hub.

[0018] In some examples, the fixing component is a welding component, or the fixing component is a component of fixing screws, bolts, and rivets.

[0019] The fixed component can be a component fixed by welding. Welded components usually achieve the purpose of fixing by melting metal at high temperature to form a strong connection between metals. Welding technology is used to fix various metal structures, such as steel structures, pipeline systems, etc., with high reliability and durability. Here, the filler plate can be welded to the hub and the assembly groove can be sealed.

[0020] A fixing component can also be a component that is fixed by using fixing screws, bolts or rivets. These components mechanically connect the parts together to form a whole. Fixing screws are usually screwed into the material by threading, using friction and mechanical bite to achieve fixation; fixing bolts are fastened by passing through preset holes and matching nuts; rivets achieve the effect of fixing by tightly combining the rivet head and tail together through the riveting process.

[0021] In some examples, two welding assemblies are provided, and the two welding assemblies weld two sides of the filling plate simultaneously.

[0022] The welding assembly is configured as two. The two welding assemblies are designed to perform welding operations simultaneously so as to weld both sides of the filler plate. In this way, the welding process can complete the welding work on both sides of the filler plate at the same time, thereby improving production efficiency and welding quality. Through this method of simultaneous welding on both sides, it can ensure that the welding seams on both sides of the filler plate are uniform, reduce the possibility of welding defects, and further improve the stability and reliability of the overall welding assembly.

[0023] In some examples, the conveying assembly includes a conveying mechanism and a guide structure, the conveying mechanism is in driving connection with the filling plate before connection, the conveying mechanism is capable of conveying the filling plate, and the guide structure is used to guide the shape and / or conduction direction of the filling plate.

[0024] The conveying assembly consists of two main parts: the conveying mechanism and the guide structure. The conveying mechanism and the filling plate are connected by transmission before connection, ensuring that the conveying mechanism can effectively convey the filling plate. The design and construction of the conveying mechanism enable it to move the filling plate smoothly, ensuring the efficiency and stability of the entire conveying process. The guide structure plays a key guiding role, ensuring that the filling plate maintains the correct shape and direction during the conveying process. Through the precise design of the guide structure, the filling plate can be effectively prevented from being offset or deformed during the conveying process, thereby ensuring the accurate alignment and efficient handling of the filling plate in the subsequent process. The guide structure can also transmit the direction of the filling plate, so that it moves according to the predetermined path and direction, further improving the accuracy and reliability of the entire conveying system.

[0025] In some examples, the conveying assembly further includes two bending mechanisms, one bending mechanism being disposed on each side of the guide structure;

[0026] The conveying mechanism can also convey the edge locking plate, which is bent by the bending mechanism to form an edge locking portion, and the shape of the edge locking portion is adapted to the edge position of the side wall in the assembly groove.

[0027] The conveying assembly not only includes a guide structure, but is also further equipped with a bending mechanism. Two bending mechanisms are respectively arranged on both sides of the guide structure to facilitate bending of the materials corresponding to the edge locking part during the conveying process. The function of the conveying mechanism is not limited to conveying ordinary plates, but also includes the ability to convey specific edge locking plates. When the edge locking plate passes through the bending mechanism, the bending mechanism will apply pressure to the edge locking plate, causing it to bend and deform at a specific position, thereby forming a edge locking portion. Specifically, the edge locking portion can be formed by squeezing the edge locking plate toward the bending groove through a bending wheel. The shape of the edge locking portion can perfectly match the side wall edge position in the assembly groove, ensuring the stability and sealing of the edge locking plate in the assembly groove. In this way, the conveying assembly not only improves the conveying efficiency, but also increases the processing capacity for plates of specific shapes, further improving the overall production efficiency and product quality.

[0028] In some examples, the fixing assembly is a welding assembly, and the welding assembly can weld the locking portion to the side wall of the assembly groove.

[0029] The fixing assembly mentioned above can be specifically configured as a welding assembly. The welding assembly has the function of welding and fixing the locking part to the inner wall of the assembly slot. In this way, the locking part can be firmly fixed to the inner wall of the assembly slot, ensuring the stability and reliability of the entire structure. The welding process usually involves high temperature and pressure, so that the locking part is tightly combined with the inner wall of the assembly slot, thereby achieving durability for long-term use. This welding fixing method can provide a very strong connection to ensure stable operation of the equipment under various working conditions.

[0030] In a second aspect, an embodiment of the present application provides a wheel hub assembly, wherein the wheel hub assembly is transformed from a pneumatic tire wheel hub to a non-pneumatic tire wheel hub by the above-mentioned wheel hub transformation device, and the wheel hub assembly comprises:

[0031] A hub structure, comprising a hub body and an assembly groove arranged on a circumferential side of the hub structure;

[0032] A filling plate surrounds the hub body and completely blocks the assembly groove. After the filling plate blocks the assembly groove, a spoke assembly surface of the non-pneumatic tire is formed.

[0033] The wheel hub assembly can convert a traditional pneumatic tire wheel hub into a wheel hub suitable for non-pneumatic tires. Specifically, the wheel hub assembly includes the following key parts:

[0034] The hub structure is the core of the entire assembly and consists of a hub body. This hub body is the foundation of the hub assembly and is responsible for bearing the weight of the entire tire and transmitting torque. Special assembly grooves are designed on the circumference of the hub body. These assembly grooves are set up for the subsequent assembly of pneumatic tires. The layout and shape of the assembly grooves are carefully designed to ensure perfect fit with the spokes of the pneumatic tire, thereby providing stable support and good mechanical properties.

[0035] The filler plate is another important component of the wheel hub assembly. The function of the filler plate is to surround the wheel hub body and completely block the assembly groove mentioned above. In this way, the filler plate not only ensures the closure of the assembly groove, but also forms a special spoke assembly surface. The spoke assembly surface is specially designed for non-pneumatic tires and can fit tightly with the spokes of non-pneumatic tires, thereby achieving a firm connection between the non-pneumatic tire and the wheel hub. The material and structural design of the filler plate need to take into account factors such as strength, durability and weight to ensure the reliability and safety of the entire wheel hub assembly in actual use.

[0036] In some examples, the filling plate is an annular iron sheet completely located in the assembly groove, and both sides of the annular iron sheet are welded to the inner wall of the assembly groove.

[0037] The filling plate can be a ring-shaped iron sheet completely embedded in the assembly groove. The edges on both sides of the ring-shaped iron sheet are accurately welded to the inner wall of the assembly groove to ensure that it is firmly fixed in the predetermined position.

[0038] In some examples, the wheel hub assembly further includes two locking portions, the two locking portions are respectively connected to two sides of the filling plate, the filling plate is in the assembly groove, and the two locking portions are respectively locked at edge positions on both sides of the assembly groove.

[0039] The wheel hub assembly not only includes a filling plate, but also further has two locking parts. The two locking parts are connected to both sides of the filling plate by welding or other methods, respectively, to ensure the stability and firmness of the filling plate. Specifically, the filling plate is placed in the assembly groove, and the two locking parts are locked at the edge positions on both sides of the assembly groove, respectively, so as to further improve the stability of the filling plate connection, reduce the possibility of failure and desoldering of the filling plate, and prevent it from displacement or falling off during use. Such a design not only improves the overall strength of the wheel hub assembly, but also ensures its reliability in various working environments.

[0040] In some examples, at least one fixing hole is provided on the circumferential side of the filling plate, and each of the fixing holes is provided with a fixing member, which passes through the fixing hole and is fixedly connected to the pneumatic tire hub.

[0041] At least one fixing hole can be provided on the edge of the filling plate as required. These fixing holes are evenly distributed on the peripheral side of the filling plate to ensure the stability and firmness of the overall structure. A corresponding fixing piece is installed on each fixing hole. These fixing pieces pass through the fixing holes and are tightly connected to the wheel hub of the pneumatic tire. In this way, the fixing piece not only plays the role of fixing the filling plate, but also ensures the close connection between the filling plate and the wheel hub, thereby improving the stability and safety of the overall structure.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] To solve the above technical problems, please refer to Figure 1-Figure 8 As shown, the first aspect of the present application proposes a wheel hub modification device 100, which can transform a traditional pneumatic tire hub into a modern non-pneumatic tire hub, and can reduce glue and labor costs, resulting in lower costs and higher overall performance of the non-pneumatic tire after modification.

[0055] Please refer to Figure 1-Figure 3 As shown, in some examples, the wheel hub modification device 100 is used to modify a pneumatic tire wheel hub into a non-pneumatic tire wheel hub, and the outer peripheral side of the pneumatic tire wheel hub is provided with a mounting groove 212. The wheel hub modification device 100 can modify and fill the mounting groove 212. The wheel hub modification device 100 includes:

[0056] The device body 110 has a hub mounting portion 111, and the pneumatic tire hub is mounted on the hub mounting portion 111;

[0057] A driving member 120 is mounted on the device body 110, and the pneumatic tire hub can be connected to the driving member 120 and rotate with the driving member 120;

[0058] The conveying assembly 130 is installed on the equipment body 110. The conveying assembly 130 is arranged on one side of the pneumatic tire hub. The conveying assembly 130 can convey the filling plate 220 and place the filling plate 220 partially in the assembly groove 212.

[0059] A fixing assembly 140 is installed on the device body 110, and the fixing assembly 140 can fix the filling plate 220 to the pneumatic tire hub;

[0060] After the driving member 120 drives the pneumatic tire to rotate one circle, the filling plate 220 surrounds the pneumatic tire hub and completely blocks the assembly groove 212. After the filling plate 220 blocks the assembly groove 212, a spoke assembly surface of the non-pneumatic tire is formed.

[0061] The wheel hub modification device 100 is used to transform a traditional pneumatic tire wheel hub into a modern non-pneumatic tire wheel hub. This modification process involves adjusting and modifying the structure of the original pneumatic tire wheel hub so that the modified wheel hub can adapt to the use requirements of non-pneumatic tires. In this process, the outer peripheral side of the pneumatic tire wheel hub itself is usually provided with a mounting groove 212 specifically used for mounting the pneumatic tread. The mounting groove 212 needs to be blocked during the modification process to reduce the waste of resources due to filling the mounting groove 212.

[0062] The wheel hub transformation device 100 can efficiently complete the transformation of a pneumatic tire hub to a non-pneumatic tire hub. The device mainly includes the following key parts:

[0063] The device body 110 has a hub mounting portion 111. The pneumatic tire hub can be accurately mounted and fixed on the hub mounting portion 111. The design of the device body 110 ensures the stability and accuracy of the hub during the transformation process.

[0064] The driving member 120 is a part of the wheel hub modification device 100. The driving member 120 is mounted on the device body 110 and is directly or indirectly connected to the pneumatic tire hub. The driving member 120 drives the pneumatic tire hub to rotate. During the modification process, the driving member 120 drives the pneumatic tire hub to rotate one circle to ensure the smooth progress of the subsequent steps.

[0065] The conveying assembly 130 is a key part of the wheel hub reconstruction device 100 that is responsible for conveying the filling material. The conveying assembly 130 is also installed on the device body 110, and the conveying assembly 130 is set on one side of the pneumatic tire hub. The function of the conveying assembly 130 is to accurately convey the filling plate 220 to the specified position and ensure that the filling plate 220 is partially in the assembly groove 212. The design of the conveying assembly 130 must ensure the accurate placement of the filling plate 220 to ensure that the reconstructed wheel hub can achieve the expected performance and strength.

[0066] The fixing assembly 140 is a part of the wheel hub modification device 100 for fixing the filling plate 220. The fixing assembly 140 is also mounted on the device body 110 and can fix the filling plate 220 to the pneumatic tire hub. The design of the fixing assembly 140 must be strong and reliable enough to ensure that the filling plate 220 will not be displaced or fall off during the modification process.

[0067] During the operation of the wheel hub modification equipment 100, the conveying component 130 conveys the filling plate 220 into the assembly groove 212, and the fixing component 140 fixes the filling plate 220 to the pneumatic tire hub. At this time, the driving component 120 drives the pneumatic tire hub to rotate. The rotation is that the filling plate 220 is bent and fixed in the assembly groove 212 until the hub rotates one circle to completely seal the assembly groove 212. The sealed assembly groove 212 cooperates with the filling plate 220 to form the spoke assembly surface of the non-pneumatic tire.

[0068] After this series of steps, the filling plate 220 surrounds the pneumatic tire hub and completely blocks the assembly groove 212. After the filling plate 220 blocks the assembly groove 212, the spoke assembly surface of the non-pneumatic tire is formed, thereby completing the entire hub transformation process. In this way, the hub originally used for pneumatic tires is successfully transformed into a hub suitable for non-pneumatic tires, greatly improving the durability and safety of the hub.

[0069] At least one universal wheel 150 may be provided at the bottom of the device body 110 to facilitate the transfer of the device body 110 .

[0070] Please refer to Figure 1-Figure 3 As shown, in some examples, the fixing component 140 is a welding component, or the fixing component 140 is a component of fixing screws, bolts, and rivets.

[0071] The fixing assembly 140 may be a component fixed by a welding process. The welding assembly usually melts the metal at a high temperature to form a firm connection between the metals, thereby achieving the purpose of fixing. Welding technology is used to fix various metal structures, such as steel structures, pipeline systems, etc., and has high reliability and durability. Here, the filling plate 220 can be welded to the wheel hub, and the assembly groove 212 is sealed.

[0072] The fixing component 140 can also be a component that achieves the purpose of fixing by using fixing screws, bolts or rivets. These components tightly connect the various parts together by mechanical means to form a whole. Fixing screws are usually screwed into the material by threads, and fixation is achieved by friction and mechanical bite; fixing bolts are fastened by passing through preset holes and matching nuts; rivets are fixed by tightly combining the rivet head and tail together through a riveting process. These mechanical fixing methods are widely used in various mechanical equipment, building structures and daily necessities, and have the advantages of simple operation and easy disassembly.

[0073] Please refer to Figure 1-Figure 3 As shown, in some examples, two welding assemblies are provided, and the two welding assemblies weld both sides of the filling plate 220 simultaneously.

[0074] The welding assembly is configured as two. The two welding assemblies are designed to perform welding operations simultaneously so as to weld both sides of the filling plate 220. In this way, the welding process can complete the welding work on both sides of the filling plate 220 at the same time, thereby improving production efficiency and welding quality. Through this method of simultaneous welding on both sides, it is possible to ensure that the welding seams on both sides of the filling plate 220 are uniform, reduce the possibility of welding defects, and further improve the stability and reliability of the overall welding assembly.

[0075] Please refer to Figure 1-Figure 3 As shown, in some examples, the conveying assembly 130 includes a conveying mechanism 131 and a guide structure 1311. The conveying mechanism 131 is transmission-connected to the filling plate 220 before connection. The conveying mechanism 131 is capable of conveying the filling plate 220. The guide structure 1311 is used to guide the shape and / or conduction direction of the filling plate 220.

[0076] The conveying assembly 130 includes two main parts: a conveying mechanism 131 and a guide structure 1311. The conveying mechanism 131 is connected to the filling plate 220 by transmission before connection, ensuring that the conveying mechanism 131 can effectively convey the filling plate 220. The design and construction of the conveying mechanism 131 enable it to smoothly move the filling plate 220, ensuring the efficiency and stability of the entire conveying process. The guide structure 1311 plays a key guiding role, and the guide structure 1311 ensures that the filling plate 220 maintains the correct shape and direction during the conveying process. Through the precise design of the guide structure 1311, the filling plate 220 can be effectively prevented from being offset or deformed during the conveying process, thereby ensuring the accurate alignment and efficient processing of the filling plate 220 in the subsequent process. The guide structure 1311 can also conduct the direction of the filling plate 220, so that it moves according to the predetermined path and direction, further improving the accuracy and reliability of the entire conveying system.

[0077] Please refer to Figure 1-Figure 3 As shown, in some examples, the conveying assembly 130 further includes two bending mechanisms 132 , and one bending mechanism 132 is respectively disposed on both sides of the guide structure 1311 ;

[0078] The conveying mechanism 131 can also convey the locking plate, which is bent by the bending mechanism 132 to form a locking portion 230 . The shape of the locking portion 230 is adapted to the edge position of the side wall in the assembly groove 212 .

[0079] The conveying assembly 130 not only includes a guide structure 1311, but is also further equipped with a bending mechanism 132. Two bending mechanisms 132 are respectively arranged on both sides of the guide structure 1311, so as to facilitate bending of the materials corresponding to the edge locking portion 230 during the conveying process. The function of the conveying mechanism 131 is not limited to conveying ordinary plates, but also includes being able to convey specific edge locking plates. When the edge locking plate passes through the bending mechanism 132, the bending mechanism 132 will apply pressure to the edge locking plate, causing it to bend and deform at a specific position, thereby forming the edge locking portion 230. Specifically, the edge locking portion 230 can be formed by squeezing the edge locking plate toward the bending groove 1321 by the bending wheel 1322. The shape of the edge locking portion 230 can be perfectly matched with the side wall edge position in the assembly groove 212, ensuring the stability and sealing of the edge locking plate in the assembly groove 212. In this way, the conveying assembly 130 not only improves the conveying efficiency, but also increases the processing capacity of plates of specific shapes, further improving the overall production efficiency and product quality.

[0080] In some examples, the fixing assembly 140 is a welding assembly, and the welding assembly can weld the locking portion 230 to the side wall of the assembly groove 212 .

[0081] The fixing assembly 140 mentioned above can be specifically configured as a welding assembly. The welding assembly has the function of welding and fixing the locking portion 230 to the inner wall of the assembly groove 212. In this way, the locking portion 230 can be firmly fixed to the inner wall of the assembly groove 212, ensuring the stability and reliability of the entire structure. The welding process usually involves high temperature and pressure, so that the locking portion 230 is tightly combined with the inner wall of the assembly groove 212, thereby achieving durability for long-term use. This welding fixing method can provide a very strong connection to ensure stable operation of the device under various working conditions.

[0082] The thickness of the filling plate 220 is 2 mm±1 mm, and the thickness of the locking edge portion 230 is 1 mm±0.5 mm.

[0083] The thickness of the filling plate 220 is 2 mm, and the allowable error range is plus or minus 1 mm, which means that the actual thickness of the filling plate 220 can be selected between 1 mm and 3 mm. The thickness of the locking edge portion 230 is 1 mm, and the allowable error range is plus or minus 0.5 mm, which means that the actual thickness of the locking edge portion 230 can be selected between 0.5 mm and 1.5 mm. The appropriate thickness is selected according to actual needs.

[0084] Please refer to Figure 4-Figure 8 As shown, in a second aspect, the embodiment of the present application provides a wheel hub assembly 200, which is transformed from a pneumatic tire wheel hub to a non-pneumatic tire wheel hub by the above-mentioned wheel hub transformation device 100, and the wheel hub assembly 200 includes:

[0085] The hub structure 210 includes a hub body 211 and a mounting groove 212 disposed on the circumference of the hub structure 210;

[0086] The filling plate 220 surrounds the hub body 211 and completely blocks the assembly groove 212 . After the filling plate 220 blocks the assembly groove 212 , a spoke assembly surface of the non-pneumatic tire is formed.

[0087] The wheel hub assembly 200 can convert a conventional pneumatic tire wheel hub into a wheel hub suitable for a non-pneumatic tire. Specifically, the wheel hub assembly 200 includes the following key parts:

[0088] The hub structure 210 is the core part of the entire assembly and is composed of a hub body 211. The hub body 211 is the foundation of the hub assembly 200 and is responsible for bearing the weight of the entire tire and transmitting torque. Special assembly grooves 212 are designed on the circumferential side of the hub body 211. These assembly grooves 212 are provided for the subsequent assembly of the pneumatic tire. The layout and shape of the assembly grooves 212 are carefully designed to ensure perfect fit with the spokes of the pneumatic tire, thereby providing stable support and good mechanical properties.

[0089] The filling plate 220 is another important component of the wheel hub assembly 200. The function of the filling plate 220 is to surround the wheel hub body 211 and completely block the assembly groove 212 mentioned above. In this way, the filling plate 220 not only ensures the closure of the assembly groove 212, but also forms a special spoke assembly surface. The spoke assembly surface is specially designed for non-pneumatic tires and can fit tightly with the spokes of the non-pneumatic tire, thereby achieving a firm connection between the non-pneumatic tire and the wheel hub. The material and structural design of the filling plate 220 need to take into account factors such as strength, durability and weight to ensure the reliability and safety of the entire wheel hub assembly 200 in actual use.

[0090] The hub assembly 200 of the present application successfully transforms the traditional pneumatic tire hub into a hub suitable for non-pneumatic tires through the hub structure 210 and the filling plate 220. This transformation not only improves the durability and safety of the tire, but also provides users with more choices and convenience.

[0091] Please refer to Figure 4-Figure 8 As shown, in some examples, the filling plate 220 is an annular iron sheet completely located in the assembly groove 212 , and both sides of the annular iron sheet are welded to the inner wall of the assembly groove 212 .

[0092] The filling plate 220 can be an annular iron sheet completely embedded in the assembly groove 212. The edges on both sides of the annular iron sheet are precisely welded to the inner wall of the assembly groove 212 to ensure that it is firmly fixed in a predetermined position.

[0093] In some examples, the hub assembly 200 further includes two locking portions 230 , which are respectively connected to two sides of the filling plate 220 , the filling plate 220 is in the assembly groove 212 , and the two locking portions 230 are respectively locked at the edge positions on both sides of the assembly groove 212 .

[0094] The hub assembly 200 not only includes a filling plate 220, but also further has two locking portions 230. The two locking portions 230 are respectively connected to the two sides of the filling plate 220 by welding or the like, thereby ensuring the stability and firmness of the filling plate 220. Specifically, the filling plate 220 is placed in the assembly groove 212, and the two locking portions 230 are respectively locked at the edge positions on both sides of the assembly groove 212, thereby further improving the stability of the connection of the filling plate 220, reducing the possibility of failure and desoldering of the filling plate 220, and preventing it from being displaced or falling off during use. Such a design not only improves the overall strength of the hub assembly 200, but also ensures its reliability in various working environments.

[0095] In some examples, at least one fixing hole is disposed on the circumferential side of the filling plate 220 , and each fixing hole is provided with a fixing member, which passes through the fixing hole and is fixedly connected to the pneumatic tire hub.

[0096] At least one fixing hole can be provided on the edge of the filling plate 220 as needed. These fixing holes are evenly distributed on the peripheral side of the filling plate 220 to ensure the stability and firmness of the overall structure. A corresponding fixing piece is installed on each fixing hole. These fixing pieces pass through the fixing holes and are tightly connected to the wheel hub of the pneumatic tire. In this way, the fixing piece not only plays a role in fixing the filling plate 220, but also ensures the tight connection between the filling plate 220 and the wheel hub, thereby improving the stability and safety of the overall structure.

[0097] The material of the filling plate 220 is one of iron, iron alloy, aluminum, aluminum alloy, copper, and copper alloy. The filling plate 220 of the present application is a filling plate 220 on a wheel hub in a tire, which is used to save materials.
