Description

Technical Field

[0001] This utility model relates to the field of steel wire ring technology, specifically a steel wire ring for all-steel radial tires. Background Technology

[0002] The steel wire bead of an all-steel radial tire is a key core component. It is mainly used to cooperate with the rim to bear the radial load, circumferential tension, and lateral force generated by the tire during driving and load-bearing. It maintains the stability of the tire's ring structure and ensures the overall load-bearing performance and driving safety of the tire. Its structural design and performance directly affect the service life and reliability of the all-steel radial tire. It is widely used in commercial vehicles, heavy engineering machinery vehicles, and other fields with high requirements for tire load-bearing capacity and durability.

[0003] In existing technologies, the structural design of steel radial tire wire rings is relatively simple, often employing a single layer of steel wire wrapped with rubber. The components are connected solely by the adhesive force of the rubber coating, lacking effective mechanical interlocking or locking structures. This results in weak connection stability and overall integrity between components, making them prone to separation under long-term repeated stress or vibration due to weakening or failure of adhesive force. Furthermore, the steel wires in traditional wire rings are mostly arranged in a unidirectional spiral without a dedicated buffer structure, failing to effectively counteract the torsional stress generated during tire operation and absorbing radial impacts. This easily leads to stress concentration in localized areas of the wire ring, causing early cracking and affecting its fatigue resistance and service life. In addition, existing wire rings have shortcomings in heat dissipation design. Either they lack heat dissipation holes, preventing timely heat dissipation, or they use uniformly distributed, single-shaped heat dissipation holes, which, while providing some cooling, can weaken the structural strength of the wire ring body due to improper hole design. Therefore, a new type of steel radial tire wire ring is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an all-steel radial tire wire ring to solve the technical problem mentioned above, which is that the lack of an effective mechanical interlocking or locking structure leads to weak connection stability and integrity between components, and makes the components prone to separation due to weakening or failure of adhesive force under long-term repeated stress or vibration conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel radial tire wire ring, comprising:

[0006] A wire assembly, and an outer connecting plate disposed on the front and back of the wire assembly, wherein the wire assembly is composed of an outer wire ring, an inner wire ring and a buffer ring, wherein the buffer ring is disposed between the outer wire ring and the inner wire ring;

[0007] The outer steel wire ring and the inner steel wire ring are designed with right-hand spiral winding and left-hand spiral winding, respectively. The buffer ring is a ring-shaped rubber elastomer, and axial pressure relief holes are evenly opened along the circumference on the surface of the buffer ring. The upper surface and the inner surface of the buffer ring are respectively provided with arc-shaped protrusions and arc-shaped grooves. The buffer ring engages with the outer steel wire ring through the arc-shaped protrusions, and the buffer ring engages with the inner steel wire ring through the arc-shaped grooves.

[0008] The heat dissipation outer hole and the heat dissipation inner hole are respectively opened on the upper and lower parts of the front side of the outer connecting plate, and the heat dissipation outer hole and the heat dissipation inner hole correspond to the outer side and the inner side of the steel wire assembly, respectively. The inner walls of the heat dissipation outer hole and the heat dissipation inner hole are coated with a graphene thermal conductive coating, and the heat dissipation outer hole and the heat dissipation inner hole are cylindrical and conical, respectively.

[0009] First, assemble the wire assembly: Following the pre-set winding method, fabricate the inner and outer wire coils. The inner wire coil uses a left-hand spiral winding design, while the outer wire coil uses a right-hand spiral winding design. Next, take a buffer ring, which is a ring-shaped rubber elastomer with axial pressure relief holes evenly distributed along its circumference. Its upper surface has arc-shaped protrusions, and its inner surface has arc-shaped grooves. Place the buffer ring between the inner and outer wire coils, allowing it to engage with the outer wire coil through its arc-shaped protrusions and with the inner wire coil through its arc-shaped grooves, thus completing the assembly of the wire assembly.

[0010] Next, install the outer connecting plates: place the outer connecting plates on the front and back of the steel wire assembly respectively. The upper part of the front of the outer connecting plate has a heat dissipation outer hole, and the lower part of the front has a heat dissipation inner hole. The heat dissipation outer hole corresponds to the outer side of the steel wire assembly, and the heat dissipation inner hole corresponds to the inner side of the steel wire assembly. The heat dissipation outer hole has a cylindrical structure, and the heat dissipation inner hole has a conical structure. At the same time, ensure that the inner walls of both the heat dissipation outer hole and the heat dissipation inner hole have been pre-coated with a graphene thermal conductive coating to complete the overall assembly of the steel wire ring of the all-steel radial tire.

[0011] When the steel wire bead of an all-steel radial tire is in operation, the torsional stress generated by the tire's rotation acts on the wire assembly. Since the inner wire bead is wound in a left-hand spiral and the outer wire bead is wound in a right-hand spiral, and the two are interlocked, this interlocking structure can directly offset part of the torsional stress. At the same time, the radial impact received by the tire during driving is transmitted to the buffer ring. The buffer ring, as a ring-shaped rubber elastomer, undergoes elastic deformation to absorb the radial impact energy. During this process, the axial pressure relief holes on the surface of the buffer ring simultaneously release the internal pressure generated by the impact, preventing pressure accumulation from damaging the wire assembly.

[0012] The heat generated during the operation of the wire coil is first transferred to the wire assembly, and then some of the heat is transferred to the outer connecting plate. Due to the conical structure of the heat dissipation inner hole, its "flow guiding effect" can accelerate the exhaust of hot air from the inside of the wire assembly to the outside. The cylindrical structure of the heat dissipation outer hole helps to exhaust heat from the outside of the wire assembly while ensuring the structural stability of the outer connecting plate. At the same time, the graphene thermally conductive coating on the inner wall of the heat dissipation outer hole and the heat dissipation inner hole improves the heat conduction efficiency, quickly transferring the heat from the wire assembly and the outer connecting plate to the heat dissipation hole. Combined with the aluminum foil heat dissipation film wrapped around the outer side of the wire coil ring body, the heat is further dissipated to the external environment, achieving continuous heat dissipation.

[0013] Preferably, the inner cavity of the steel wire assembly is provided with connecting seats around it, and the inner side of the connecting seat is in close contact with the outer surface of the outer connecting plate.

[0014] By setting connecting seats around the inner cavity of the steel wire assembly and ensuring that the inner side of the connecting seats is tightly fitted to the outer surface of the outer connecting plate, the contact area between the steel wire assembly and the outer connecting plate can be significantly increased, making the force transmission between the two more uniform and avoiding local stress concentration. At the same time, the tightly fitted structure can effectively limit the relative sliding between the steel wire assembly and the outer connecting plate, improve the stability of the connection between the two, lay a good foundation for the installation of other components, and ensure the initial assembly accuracy of the overall structure.

[0015] Preferably, the connecting seat and the corresponding position of the outer connecting plate are provided with connecting holes, and a guide stud is provided between adjacent outer connecting plates, and the end of the guide stud extends outward along the connecting hole.

[0016] Connecting holes are made at the corresponding positions of the connecting seat and the outer connecting plate to achieve precise positioning and installation of the guide studs, preventing the guide studs from shifting during installation and ensuring the connection accuracy between adjacent outer connecting plates. The setting of the guide studs can effectively connect adjacent outer connecting plates to form a rigid connection structure, enhancing the overall deformation resistance of the outer connecting plates. At the same time, the structure of the guide stud end extending outward along the connecting hole provides operating space for the installation of subsequent fixing components such as nuts, facilitating the assembly and disassembly of the overall structure.

[0017] Preferably, each end of the connecting stud is threaded with a nut, and a spring washer is provided between the connecting seat and the nut, with the spring washer sleeved on the surface of the connecting stud.

[0018] The threaded connection between the stud and the nut allows for a detachable connection, facilitating subsequent structural maintenance and component replacement. The spring washer utilizes the reaction force generated by its elastic deformation to effectively prevent the nut from loosening due to vibration or other factors during long-term use, ensuring connection stability. Simultaneously, the spring washer disperses the pressure of the nut on the outer surface of the connector during tightening, preventing damage to the outer surface of the connector due to excessive local pressure and extending the service life of the connector.

[0019] Preferably, the upper surface of the connecting stud is provided with transverse grooves at both the front and rear ends, and a retaining post is rotatably connected to the rear end of the inner cavity of the transverse groove, and the outer end of the retaining post is attached to the corresponding inner side of the outer connecting plate.

[0020] The transverse groove provides installation space for the locking post while restricting its installation position, ensuring its precise function. The rotating connection structure between the locking post and the transverse groove allows the angle of the locking post to be adjusted according to the actual situation of the inner side of the outer connecting plate, ensuring a tight fit between the outer end of the locking post and the inner side of the outer connecting plate. The locking post also acts as a lateral limiter for the outer connecting plate, restricting its axial or radial displacement along the guide stud, further improving the connection stability between the outer connecting plate and the guide stud, preventing the outer connecting plate from shifting under stress, and ensuring the overall structural stress balance.

[0021] Preferably, each of the transverse grooves has a compression spring at its front end, and the top of the compression spring is connected to the lower front end of the locking post.

[0022] The connection structure between the compression spring and the locking post provides continuous elastic pressure to the locking post, ensuring that the outer end of the locking post is always in close contact with the inner side of the outer connecting plate. Even if slight wear occurs on the outer connecting plate or the locking post during long-term use, the compression spring can compensate for the wear through its own deformation, maintaining the positioning effect of the locking post. At the same time, the compression spring can also buffer the impact force transmitted from the outer connecting plate to the locking post, reduce stress concentration at the connection between the locking post and the transverse groove, prevent the locking post from breaking due to excessive force, extend the service life of the locking post, and further ensure the stability and reliability of the overall structure.

[0023] Compared with the prior art, this utility model provides a steel radial tire wire ring, which has the following beneficial effects:

[0024] This all-steel radial tire's steel wire ring adopts a nested structure of "inner steel wire ring, middle buffer ring, and outer steel wire ring," combined with a combination of "bidirectional spiral nesting and rubber buffer layer interlocking." This achieves mechanical locking between the steel wire ring and the buffer layer. Compared to the traditional structure that relies solely on adhesive bonding, this significantly improves the stability and integrity of the connection between components, avoiding component separation due to insufficient adhesion. The inner steel wire ring uses a left-hand spiral winding design, while the outer steel wire ring uses a right-hand spiral winding design, with the two steel wire rings interlocking. This arrangement effectively counteracts the torsional stress generated during tire use. Combined with the elastic deformation capability of the middle buffer ring as a ring-shaped rubber elastomer, it can fully absorb radial impact, thus solving the problem of early cracking caused by stress concentration in traditional steel wire rings. This significantly improves the fatigue resistance and overall service life of the steel wire ring.

[0025] In terms of heat dissipation performance, the upper and lower parts of the front of the outer connecting plate are respectively provided with heat dissipation outer holes and heat dissipation inner holes, which correspond to the outer and inner sides of the steel wire assembly, respectively. At the same time, the steel wire ring annular body is provided with an annular array of heat dissipation holes along the circumferential direction. The heat dissipation holes are designed in the form of alternating inner and outer layer holes, where the inner layer holes are conical and the outer layer holes are cylindrical. This heat dissipation hole structure of "gradient hole diameter + alternating arrangement" is different from the traditional design of no holes or uniform circular holes. The conical inner layer holes can accelerate the discharge of hot air by using the flow guiding effect, while the cylindrical outer layer holes can effectively enhance the structural stability of the steel wire ring annular body while ensuring the heat dissipation effect, and avoid affecting the structural strength due to excessive opening.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a technical solution: a steel radial tire wire ring, comprising: (see details) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A steel radial tire wire ring, comprising:

[0035] The steel wire assembly 1 and the outer connecting plate 5 disposed on the front and back of the steel wire assembly 1, and the steel wire assembly 1 is composed of an outer steel wire ring 2, an inner steel wire ring 3 and a buffer ring 4, with the buffer ring 4 disposed between the outer steel wire ring 2 and the inner steel wire ring 3.

[0036] The outer steel wire ring 2 and the inner steel wire ring 3 are designed with right-hand spiral winding and left-hand spiral winding, respectively. The buffer ring 4 is an annular rubber elastomer, and axial pressure relief holes are evenly opened on the surface of the buffer ring 4 along the circumferential direction. The upper surface and the inner side of the buffer ring 4 are respectively provided with arc-shaped protrusions and arc-shaped grooves. The buffer ring 4 is engaged with the outer steel wire ring 2 through the arc-shaped protrusions, and the buffer ring 4 is engaged with the inner steel wire ring 3 through the arc-shaped grooves.

[0037] The heat dissipation outer hole 6 and the heat dissipation inner hole 7 are respectively opened on the upper and lower parts of the front side of the outer connecting plate 5, and the heat dissipation outer hole 6 and the heat dissipation inner hole 7 correspond to the outer side and the inner side of the steel wire assembly 1, respectively. The inner walls of the heat dissipation outer hole 6 and the heat dissipation inner hole 7 are coated with a graphene thermal conductive coating, and the heat dissipation outer hole 6 and the heat dissipation inner hole 7 are cylindrical and conical, respectively.

[0038] First, assemble the wire assembly 1: Following the preset winding method, fabricate the inner wire ring 3 and the outer wire ring 2, where the inner wire ring 3 uses a left-handed spiral winding design, and the outer wire ring 2 uses a right-handed spiral winding design. Next, take the buffer ring 4, which is a ring-shaped rubber elastomer with axial pressure relief holes evenly distributed along its circumference. Its upper surface has arc-shaped protrusions, and its inner surface has arc-shaped grooves. Place the buffer ring 4 between the inner wire ring 3 and the outer wire ring 2, allowing it to engage with the outer wire ring 2 through its arc-shaped protrusions and with the inner wire ring 3 through its arc-shaped grooves, thus completing the assembly of the wire assembly 1.

[0039] Next, install the outer connecting plate 5: Place the outer connecting plate 5 on the front and back of the wire assembly 1 respectively. The upper part of the front of the outer connecting plate 5 is provided with a heat dissipation outer hole 6, and the lower part of the front is provided with a heat dissipation inner hole 7. The heat dissipation outer hole 6 corresponds to the outer side of the wire assembly 1, and the heat dissipation inner hole 7 corresponds to the inner side of the wire assembly 1. The heat dissipation outer hole 6 is a cylindrical structure, and the heat dissipation inner hole 7 is a conical structure. At the same time, ensure that the inner walls of the heat dissipation outer hole 6 and the heat dissipation inner hole 7 are pre-coated with a graphene thermal conductive coating to complete the overall assembly of the all-steel radial tire wire ring.

[0040] When the steel wire ring of the all-steel radial tire works with the tire, the torsional stress generated by the tire's rotation acts on the wire assembly 1. Since the inner wire ring 3 is wound in a left-hand spiral and the outer wire ring 2 is wound in a right-hand spiral, and the two are interlocked, this interlocking structure can directly offset part of the torsional stress. At the same time, the radial impact received by the tire during driving is transmitted to the buffer ring 4. The buffer ring 4, as a ring-shaped rubber elastomer, undergoes elastic deformation to absorb the radial impact energy. During this process, the axial pressure relief holes on the surface of the buffer ring 4 simultaneously release the internal pressure generated by the impact, preventing pressure accumulation from damaging the wire assembly 1.

[0041] The heat generated during the operation of the wire coil is first transferred to the wire assembly 1, and then some of the heat is transferred to the outer connecting plate 5. Since the heat dissipation inner hole 7 has a conical structure, its "flow guiding effect" can accelerate the exhaust of hot air from the inside of the wire assembly 1 to the outside. The heat dissipation outer hole 6 has a cylindrical structure, which, while ensuring the structural stability of the outer connecting plate 5, helps to exhaust the heat from the outside of the wire assembly 1. At the same time, the graphene thermally conductive coating on the inner wall of the heat dissipation outer hole 6 and the heat dissipation inner hole 7 improves the heat conduction efficiency, and quickly conducts the heat on the wire assembly 1 and the outer connecting plate 5 to the heat dissipation hole. Combined with the aluminum foil heat dissipation film wrapped around the outer side of the wire coil ring body, the heat is further dissipated to the external environment to achieve continuous heat dissipation.

[0042] The staggered interlocking design of the inner steel wire ring 3 with the left-hand spiral winding and the outer steel wire ring 2 with the right-hand spiral winding can directly offset the torsional stress generated during tire operation. At the same time, the annular rubber elastomer structure of the buffer ring 4 can absorb radial impact through elastic deformation, avoiding stress accumulation in the steel wire assembly 1. This solves the problem of early cracking caused by stress concentration in the traditional single annular steel wire bundle structure and significantly improves the fatigue life of the steel wire ring.

[0043] The structure employs an alternating arrangement of external heat dissipation holes 6 and internal heat dissipation holes 7. The conical internal heat dissipation holes 7 have a "flow guiding effect" that accelerates the discharge of hot air, while the cylindrical external heat dissipation holes 6 ensure structural stability. At the same time, the graphene thermally conductive coating on the inner wall of the heat dissipation holes improves the heat conduction efficiency. Combined with the aluminum foil heat dissipation film on the outer side of the steel wire ring body, a composite heat dissipation system is formed, which effectively solves the problem of rubber aging caused by high-speed driving heat in traditional steel wire rings and reduces the working temperature of the steel wire ring.

[0044] Breaking away from the traditional "single steel wire bundle + adhesive coating" structure, a mechanical locking method is used to achieve a stable connection between the various parts of the steel wire assembly 1 through the engagement of the arc-shaped protrusion of the buffer ring 4 with the outer steel wire ring 2 and the engagement of the arc-shaped groove with the inner steel wire ring 3. Compared with the traditional structure that relies solely on adhesive coating, the connection reliability is higher. At the same time, the design of the cylindrical heat dissipation hole 6 on the outer connecting plate 5 not only achieves the heat dissipation function, but also avoids the reduction of the structural strength of the outer connecting plate 5 due to the hole design, thus ensuring the overall structural stability.

[0045] The axial pressure relief holes evenly opened along the circumference on the surface of the buffer ring 4 can release the internal pressure in time when the buffer ring 4 absorbs radial impact and undergoes elastic deformation, thus avoiding long-term pressure acting on the steel wire assembly 1 and the outer connecting plate 5, further protecting each structural component and extending the overall service life.

[0046] Please see Figure 2 Connecting seats 8 are provided around the inner cavity of the steel wire assembly 1, and the inner side of the connecting seat 8 is in close contact with the outer surface of the outer connecting plate 5.

[0047] After the connecting seat 8 is initially fixed, the outer connecting plate 5 is placed inside the connecting seat 8. By adjusting the position of the outer connecting plate 5, the inner side of the connecting seat 8 and the outer surface of the outer connecting plate 5 are completely and tightly fitted. After fitting, the connecting seat 8 is finally fixed to ensure that the fitting state of the two is stable. By setting the connecting seat 8 around the inner cavity of the steel wire assembly 1 and making the inner side of the connecting seat 8 fit tightly with the outer surface of the outer connecting plate 5, the contact area between the steel wire assembly 1 and the outer connecting plate 5 can be greatly increased, making the force transmission between the two more uniform and avoiding local stress concentration. At the same time, the tightly fitted structure can effectively limit the relative sliding between the steel wire assembly 1 and the outer connecting plate 5, improve the stability of the connection between the two, lay a good foundation for the installation of other components, and ensure the initial assembly accuracy of the overall structure.

[0048] Please see Figure 4 , Figure 5 and Figure 6 The connecting seat 8 and the outer connecting plate 5 are provided with corresponding connecting holes, and a guide stud 9 is provided between adjacent outer connecting plates 5, with the end of the guide stud 9 extending outward along the connecting hole.

[0049] The guide stud 9 is inserted between adjacent outer connecting plates 5, with both ends of the guide stud 9 passing through the corresponding connecting holes on the connecting seat 8 and the outer connecting plate 5, ensuring that the end of the guide stud 9 extends outward along the connecting hole to a preset length to meet the installation requirements of subsequent components. Connecting holes are opened at corresponding locations on the connecting seat 8 and the outer connecting plate 5 to achieve precise positioning and installation of the guide stud 9, preventing misalignment during installation and ensuring the connection accuracy between adjacent outer connecting plates 5. The guide stud 9 effectively connects adjacent outer connecting plates 5, forming a rigid connection structure and enhancing the overall deformation resistance of the outer connecting plates 5. Simultaneously, the outward extension of the end of the guide stud 9 along the connecting hole provides operating space for the installation of subsequent fixing components such as the nut 10, facilitating the assembly and disassembly of the overall structure.

[0050] The ends of the connecting studs 9 are threaded with nuts 10, and spring washers 11 are provided between the connecting seat 8 and the nuts 10, with the spring washers 11 fitted on the surface of the connecting studs 9.

[0051] After the guide stud 9 extends outward along the connecting hole, first insert the spring washer 11 from the end of the guide stud 9, allowing the spring washer 11 to slide along the surface of the guide stud 9 until it is in contact with the outer surface of the connecting seat 8; then, align the nut 10 with the thread at the end of the guide stud 9, and rotate the nut 10 clockwise, so that the nut 10 gradually moves closer to the spring washer 11 along the thread of the guide stud 9 until the nut 10 and the spring washer 11 are in tight contact, and continue to rotate the nut 10 to the preset tightening torque to ensure that the nut 10 is firmly fixed; guide stud The threaded connection between nut 9 and nut 10 allows for a detachable connection, facilitating subsequent structural maintenance and component replacement. The spring washer 11 utilizes the reaction force generated by its elastic deformation to effectively prevent nut 10 from loosening due to vibration or other factors during long-term use, ensuring connection stability. Simultaneously, the spring washer 11 can also disperse the pressure of nut 10 on the outer surface of connector 8 during the tightening process, preventing damage to the outer surface of connector 8 due to excessive local pressure and extending the service life of connector 8.

[0052] The upper surface of the connecting stud 9 has transverse grooves 12 at both the front and rear ends, and a retaining stud 13 is rotatably connected to the rear end of the inner cavity of the transverse groove 12. The outer ends of the retaining stud 13 are attached to the corresponding inner side of the outer connecting plate 5.

[0053] A rotating shaft is installed at the rear end of the inner cavity of the transverse groove 12. The locking pin 13 is rotatably connected to the rear end of the inner cavity of the transverse groove 12 via the rotating shaft, ensuring that the locking pin 13 can rotate flexibly around the rotating shaft. During the assembly of the guide stud 9 and the outer connecting plate 5, the locking pin 13 is rotated to adjust its angle so that the outer end of the locking pin 13 is in contact with the corresponding position of the inner side of the outer connecting plate 5. After contact, the contact between the locking pin 13 and the inner side of the outer connecting plate 5 achieves auxiliary positioning. The opening of the transverse groove 12 provides installation space for the locking pin 13, while restricting the installation position of the locking pin 13 to ensure... The locking post 13 can function precisely; the rotating connection structure between the locking post 13 and the transverse groove 12 allows the locking post 13 to adjust its angle according to the actual situation of the inner side of the outer connecting plate 5, ensuring that the outer end of the locking post 13 fits tightly with the inner side of the outer connecting plate 5; the setting of the locking post 13 can play a transverse limiting role for the outer connecting plate 5, limiting the axial or radial displacement of the outer connecting plate 5 along the guide stud 9, further improving the connection stability between the outer connecting plate 5 and the guide stud 9, preventing the outer connecting plate 5 from shifting during the stress process, and ensuring the stress balance of the overall structure.

[0054] A compression spring 14 is provided at the front end of the inner cavity of the transverse groove 12, and the top end of the compression spring 14 is connected to the lower front end of the locking post 13.

[0055] Adjust the angle of the locking post 13 so that the lower front end of the locking post 13 is aligned with the top of the compression spring 14. Securely connect the top of the compression spring 14 to the lower front end of the locking post 13 using welding or snap-fit ​​connections. After connection, check the state of the compression spring 14 to ensure it is in a naturally extended or slightly compressed state, capable of applying a continuous elastic force to the locking post 13. The connection structure between the compression spring 14 and the locking post 13 provides continuous elastic pressure to the locking post 13, ensuring that the outer end of the locking post 13 is always tightly fitted to the inner side of the outer connecting plate 5. Even if slight wear occurs on the outer connecting plate 5 or the locking post 13 during long-term use, the compression spring 14 can compensate for the wear through its own deformation, maintaining the positioning effect of the locking post 13. Simultaneously, the compression spring 14 can buffer the impact force transmitted from the outer connecting plate 5 to the locking post 13, reducing stress concentration at the connection between the locking post 13 and the transverse groove 12, preventing the locking post 13 from breaking due to excessive force, extending its service life, and further ensuring the stability and reliability of the overall structure.

[0056] This scheme involves: manufacturing an inner steel wire ring 3 and an outer steel wire ring 2 according to a preset winding method, wherein the inner steel wire ring 3 adopts a left-hand spiral winding design and the outer steel wire ring 2 adopts a right-hand spiral winding design; taking a ring-shaped rubber elastomer material buffer ring 4, the surface of which is evenly provided with axial pressure relief holes along the circumferential direction, the upper surface is provided with an arc-shaped protrusion and the inner side is provided with an arc-shaped groove, placing the buffer ring 4 between the inner steel wire ring 3 and the outer steel wire ring 2, so that the buffer ring 4 engages with the outer steel wire ring 2 through the arc-shaped protrusion and engages with the inner steel wire ring 3 through the arc-shaped groove, thus completing the assembly of the steel wire assembly 1;

[0057] A connecting seat 8 is added around the inner cavity of the steel wire assembly 1. After the connecting seat 8 is initially fixed, the outer connecting plate 5 is placed inside the connecting seat 8. The position of the outer connecting plate 5 is adjusted so that the inner side of the connecting seat 8 and the outer surface of the outer connecting plate 5 are completely and tightly fitted. After the fit is made, the connecting seat 8 is finally fixed.

[0058] A cylindrical heat dissipation external hole 6 is opened on the upper part of the front side of the outer connecting plate 5, and a conical heat dissipation internal hole 7 is opened on the lower part of the front side. This ensures that the heat dissipation external hole 6 corresponds to the outer side of the steel wire assembly 1, and the heat dissipation internal hole 7 corresponds to the inner side of the steel wire assembly 1. Furthermore, the inner walls of both the heat dissipation external hole 6 and the heat dissipation internal hole 7 are pre-coated with a graphene thermal conductive coating.

[0059] Connecting holes are made at the corresponding positions of the connecting seat 8 and the outer connecting plate 5. The guide stud 9 is inserted between the adjacent outer connecting plates 5, so that both ends of the guide stud 9 pass through the corresponding connecting holes on the connecting seat 8 and the outer connecting plate 5 respectively, and the end of the guide stud 9 extends outward along the connecting hole to a preset length. The spring washer 11 is put into the end of the guide stud 9, so that the spring washer 11 slides along the surface of the guide stud 9 until it is in contact with the outer surface of the connecting seat 8. Then, the nut 10 is aligned with the thread at the end of the guide stud 9, and the nut 10 is rotated clockwise until it is in close contact with the spring washer 11, and then rotated to the preset tightening torque.

[0060] A transverse groove 12 is opened at the front and rear ends of the upper surface of the guide stud 9. A rotating shaft is installed at the rear end of the inner cavity of the transverse groove 12. The locking stud 13 is rotatably connected to the rear end of the inner cavity of the transverse groove 12 through the rotating shaft. The angle of the locking stud 13 is adjusted by rotating the locking stud 13 so that the outer end of the locking stud 13 fits against the corresponding position of the inner side of the outer connecting plate 5.

[0061] A compression spring 14 is added to the front end of the inner cavity of the transverse groove 12. The angle of the locking post 13 is adjusted so that the lower part of the front end of the locking post 13 is aligned with the top of the compression spring 14. The top of the compression spring 14 is fixedly connected to the lower part of the front end of the locking post 13 by welding or snap connection. Check that the compression spring 14 is in a naturally extended or slightly compressed state to complete the overall assembly of the steel wire ring of the all-steel radial tire. When the steel wire ring of the all-steel radial tire works with the tire, the torsional stress generated by the tire operation acts on the wire assembly 1. The staggered interlocking structure of the inner wire ring 3 and the outer wire ring 2 directly offsets part of the torsional stress. The radial impact received by the tire during driving is transmitted to the buffer ring 4. The buffer ring 4 undergoes elastic deformation to absorb the radial impact energy. At the same time, the axial pressure relief hole on the surface of the buffer ring 4 releases the internal pressure generated by the impact.

[0062] The heat generated during the operation of the wire coil is transferred to the wire assembly 1 and the outer connecting plate 5. The "guide effect" of the heat dissipation inner hole 7 accelerates the exhaust of hot air from the inside of the wire assembly 1 to the outside. The heat dissipation outer hole 6 assists in the exhaust of heat from the outside of the wire assembly 1. The graphene thermally conductive coating on the inner walls of the heat dissipation outer hole 6 and the heat dissipation inner hole 7 improves the heat conduction efficiency, quickly transferring heat to the heat dissipation holes. Combined with the aluminum foil heat dissipation film wrapped around the outer side of the wire coil annular body, the heat is dissipated to the external environment. The interlocking design of the inner wire coil 3 and the outer wire coil 2 offsets the torsional stress, and the buffer ring 4 absorbs radial impact, avoiding local stress accumulation and improving the fatigue life of the wire coil. The heat dissipation outer hole 6 and the heat dissipation inner hole 7 The alternating arrangement of the steel wire rings and the graphene thermal conductive coating form a composite heat dissipation system, reducing the working temperature of the steel wire rings and solving the problem of rubber aging caused by high-speed driving heat in traditional steel wire rings. The mechanical locking method between the buffer ring 4 and the outer steel wire ring 2 and the inner steel wire ring 3 improves the connection reliability. The connecting seat 8 increases the contact area between the steel wire assembly 1 and the outer connecting plate 5, making the force transmission more uniform. The guide stud 9 enhances the overall anti-deformation ability of the outer connecting plate 5. The nut 10 and the spring washer 11 prevent the connection from loosening. The locking post 13 plays a lateral limiting role for the outer connecting plate 5. The compression spring 14 provides continuous elastic pressure to the locking post 13, compensating for wear, buffering impact force, and ensuring the overall structural stability and reliability.
