[0002] Due to manufacturing processes, traditional radial tires often have continuous cut points in their carcass ply. These cut points create interfacial adhesion defects, causing shearing between the cords and rubber, resulting in defects and reduced tire lifespan. Chinese patent CN119682440A proposes a tire with continuously woven carcass ply to address the problem of cut points in the carcass ply during traditional tire manufacturing.

[0029] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] To achieve the above objectives, such as Figure 1 , Figure 2 and Figure 10 As shown, the present invention provides a wire bead structure for improving the uniformity of continuous woven tire carcass weaving, comprising: a first wire bead structure and a second wire bead structure arranged in parallel; the first wire bead structure includes a wire bead 1 and a rubber toothed bead 4, the rubber toothed bead 4 being circumferentially arranged on the outer circumferential surface of the outer ring of the wire bead 1; the second wire bead structure includes a second wire bead 5 and a second rubber toothed bead 8, the rubber toothed bead 8 being circumferentially arranged on the outer circumferential surface of the outer ring of the wire bead 5; during the continuous woven tire carcass forming process, the tire carcass cords are embedded in the tooth grooves of the rubber toothed bead 4 of the first wire bead structure, and wound along the meridian direction of the tire into the tooth grooves of the rubber toothed bead 8 of the second wire bead structure, and then rotated back to continue winding into the next tooth groove of the rubber toothed bead 4 of the first wire bead structure; in this sequence, after the tire carcass cords are continuously wound around the circumference of the wire bead structure once, a tire carcass cord tube with uniform cord arrangement is finally formed.

[0032] This invention precisely positions and guides the tire carcass cords through the grooves on the rubber toothed ring, ensuring that the cords maintain an even spacing during winding, significantly improving the uniformity of cord arrangement in continuously woven tires. The cords are wound continuously along the meridian direction, avoiding the cutting points of traditional tire carcass ply layers, eliminating interface adhesion defects in the cut area, and improving the tire's structural integrity and durability. The continuous winding method improves weaving efficiency, reduces reliance on high-precision equipment, and offers better economic benefits. The evenly arranged cords enhance the tire carcass's rigidity and load-bearing capacity, thereby extending tire lifespan.

[0033] The steel coil structure one also includes a triangular rubber layer one 2 and a positioning rubber block one 3; the triangular rubber layer one 2 is connected to the side of the steel coil one 1 near the steel coil two 5, and the positioning rubber block one 3 is disposed on the inner circular surface of the inner ring of the steel coil one 1. The triangular rubber layer one 2 enhances the structural transition stiffness between the steel coil one 1 and the tire carcass, improves the stress distribution in the bead area, and avoids stress concentration; the positioning rubber block one 3 is used to fix the position of the steel coil structure one during the winding process, prevent its displacement, and ensure the relative positioning accuracy of the two steel coil structures, thereby indirectly improving the uniformity of the cord arrangement.

[0034] The second steel wire coil structure also includes a second triangular adhesive layer 6 and a second positioning adhesive block 7. The second triangular adhesive layer 6 is connected to the side of the second steel wire coil 5 closest to the first steel wire coil 1, and the second positioning adhesive block 7 is disposed on the inner circular surface of the inner ring of the second steel wire coil 5. The second triangular adhesive layer 6 enhances the stiffness and stress transition capability of the area of ​​the second steel wire coil 5. The second positioning adhesive block 7 and the first positioning adhesive block 1 work together to ensure the parallelism and spacing consistency between the first and second steel wire coil structures, providing a stable mechanical foundation for precise winding of the cord.

[0035] To further optimize the technical solution, the cross-sectional shapes of the wire coil 1 and wire coil 2 5 include circular, hexagonal, and rectangular shapes, etc., wherein the cross-sectional radius of the circular wire coil is expressed as... r The radii of the first wire coil 1 and the second wire coil 5 are: R The cross-sectional radii of the first wire ring 1 and the second wire ring 5 are both r The central angles corresponding to the cross-sections of the first triangular adhesive layer 2 and the second triangular adhesive layer 6 are: Width is M , and 3 r ≤ M ≤5 r The widths of triangular adhesive layer 1 (2) and triangular adhesive layer 2 (6) are limited to 3. r Up to 5 r The appropriate ratio provides sufficient bonding area and structural support without being too large, which could lead to material waste or processing difficulties. This ratio ensures the mechanical compatibility between the triangular rubber layer and the steel wire ring, which helps maintain shape stability during tire vulcanization and use, and prevents uneven distribution of the cords due to local deformation.

[0036] In this embodiment, as Figure 2 and Figure 4 As shown, the radii of wire coil 1 and wire coil 2 are... R =294.5mm, the cross-sectional shape of wire ring 1 and wire ring 2 5 is circular, and the radius of the circular cross-section is... r =8mm. The central angles corresponding to the triangular adhesive layer 1 (2) and triangular adhesive layer 2 (6) are... =90°, M =32mm.

[0037] Further optimize the technical solution, the diameter of the tire carcass cords c The range is 0.1mm to 10mm, and the thickness of the adhesive coating is 0.5mm. c ~2 c That is, the width and thickness of the tire carcass cords after rubber coating. c 1 is 2 c -5 c The surface of the carcass cords used in the continuous braiding process can be coated with glue or not. In this embodiment, the diameter of the carcass cords... c The thickness of the cord after coating is 0.5mm. c 1 represents 1mm. Properly coating the tire carcass cords with adhesive enhances the adhesion between the cords and the rubber matrix, preventing slippage or detachment during use. Controlling the dimensional range after coating ensures the tire carcass cords can smoothly embed into the grooves of the rubber ring without loosening, thereby improving uniformity of arrangement and winding reliability.

[0038] To further optimize the technical solution, the materials used for the tire carcass cords include steel wire, nylon, aramid, nylon and aramid blends, polyester, or carbon fiber. A variety of material options are provided, allowing for the selection of cords with different strengths, moduli, and fatigue resistance based on the tire's intended use (e.g., passenger cars, trucks, engineering tires), thus optimizing the tire's overall performance. The design of the tooth grooves on the rubber cleats ensures that the uniformity of the arrangement during continuous weaving is unaffected by the material type.

[0039] Further optimizing the technical solution, the structural parameters of the rubber gear ring 4 and the rubber gear ring 8 include: module of m The number of teeth is z The pitch circle diameter is d The tooth tip circle diameter is da The diameter of the center tooth root circle is df The diameter of the lateral tooth root circle is di Tooth tip height is ha The height of the center tooth root is hf Tooth width is s The height of the lateral tooth root is H The total tooth height is h The pressure angle is γ The central angle corresponding to the tooth width is θ The tooth thickness is B The central angle corresponding to the tooth thickness is α The above parameters have the following relationship: (1).

[0040] In this embodiment, as Figure 3 and Figure 4As shown, rubber gear ring 4 and rubber gear ring 8 are non-standard machined parts, and their structural parameters include: module is m =1.624, number of teeth is z =375, pitch circle diameter is d =609mm, tooth tip circle diameter is da =612.248mm, center tooth root circle diameter is df =605mm, the diameter of the side tooth root circle is di =600.314mm, tooth addendum is ha =1.624mm, center tooth root height is hf =2.03mm, tooth width is s =2.551mm, side tooth root height is H =2.3431mm, total tooth height is h =3.654mm, pressure angle is γ =20°, the central angle corresponding to the tooth width is θ =0.48°, tooth thickness is B =11.314mm, the central angle corresponding to the tooth thickness is α =90°.

[0041] This invention designs the tooth profile using standardized geometric relationships, ensuring that the size of each tooth precisely matches the diameter and winding path of the tire carcass cord, preventing the tire carcass cord from jumping out of grooves, getting stuck, or shifting during winding. The precise tooth profile parameter design improves the positioning accuracy and stability of the tire carcass cord within the tooth grooves, structurally guaranteeing the uniformity of the tire carcass cord arrangement.

[0042] Further optimizing the technical solution, in the rubber toothed ring 4 and the rubber toothed ring 8, the included angle between two adjacent teeth is... θ 0, the tooth groove width between the two teeth is L 1. The width of the tooth groove base between the roots of the two teeth is L 2, and satisfy L 2≥ c 1. The tooth groove width between the tooth tips of the two teeth is L 3. The above parameters have the following relationship: (2).

[0043] In this embodiment, as Figure 6 As shown, in the rubber toothed ring 4 and the rubber toothed ring 8, the included angle between two adjacent teeth is... θ 0 = 0.96°, the width between the two teeth (tooth groove width) is L 1 = 2.551 mm, the width between the roots of the two teeth (tooth groove bottom width) is L 2 = 1.073 mm, the width between the tips of the two teeth (tooth groove width) is L3 = 3.733mm. Ensure the width of the tooth groove bottom. L 2 is greater than or equal to the diameter of the coated cord. d 1. This allows the cord to be fully embedded in the bottom of the tooth groove, achieving stable circumferential positioning. Tooth groove top width L 3 is greater than the width of the tooth groove bottom L The design of section 2 creates a guiding structure, facilitating the smooth entry of the cords into the grooves during winding and improving winding efficiency. It also prevents the cords from slipping out of the grooves under tension, ensuring that the cords maintain an even spacing after winding.

[0044] To further optimize the technical solution, the inclination angle of each tooth in the rubber toothed ring 4 and the rubber toothed ring 8 is... β The winding angle with the tire cord is equal, and its value ranges from 0.1° to 0.1°. β ≤3° or -3°≤ β ≤-0.1°. In this embodiment, as... Figure 5 As shown, the inclination angle of each tooth in the rubber toothed ring 4 and the rubber toothed ring 8 is... β =1°. The tilt angle of the teeth matches the cord winding angle, allowing the cords to naturally conform to the grooved path after being embedded in the teeth, avoiding lateral forces or friction caused by angular deviations and reducing damage to the tire carcass cords. The small tilt angle design is suitable for near-radial winding of radial tires, ensuring uniform distribution without excessively increasing the winding path length. Positive and negative angle options allow for cross-winding of the tire carcass cords in different directions, meeting the needs of different tire structures.

[0045] The technical solution is further optimized so that the distance between the first and second wire ring structures is D, and the two wire ring structures have an initial circumferential phase difference around their central rotation axis z. β 1, that is, the angle between the teeth at corresponding positions on the side view projections of rubber toothed ring 4 and rubber toothed ring 8 is β 1. Its inclination angle relative to each tooth β The same applies; the accurate assembly of the two wire ring structures can be ensured by using positioning adhesive block 3 and positioning adhesive block 7.

[0046] In this embodiment, as Figure 7 , Figure 8 and Figure 9 As shown, the distance between the first wire ring structure and the second wire ring structure is... D =648mm, the two wire loop structures have an initial circumferential phase difference around their central rotation axis z-axis. β 1 = 1°.

[0047] Circumferential initial phase difference β1. The corresponding teeth on rubber toothed rings one and two are angled in side view, matching the cord winding angle, thus achieving a smooth transition of the cord from one toothed ring to the other. This phase difference design avoids excessive bending or stretching of the cord in the transition section, reducing stress concentration and wear, and further improving the uniformity of cord arrangement and winding continuity. Positioning blocks ensure precise assembly of the phase difference, improving the manufacturing consistency of the wire coil structure.

[0048] This invention provides a wire bead structure that improves the uniformity of weaving in continuously woven tire carcasses. It effectively improves the uniformity of cord arrangement and the efficiency of winding and weaving in continuously woven tire carcasses, thereby increasing the stiffness and load-bearing capacity of continuously woven tires and extending tire service life.

[0049] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
