Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to tire structure. Background Technology

[0002] The existing all-steel radial truck and bus tires were mainly introduced by Michelin of France in the 1950s. The structure of an all-steel radial tire includes the tread, base rubber, belt layers, carcass, soft triangular rubber, hard triangular rubber, bead wear-resistant rubber, sidewall rubber, airtight layer, and transition layer. After nearly 70 years of development, all-steel radial rubber tires have significant advantages in performance and fuel consumption, and are now widely used globally.

[0003] The manufacturing steps of all-steel radial rubber tires are as follows: first, the rubber compound is mixed in a mixer, then the components are produced by extrusion or calendering, the components are combined to produce a tire blank using a molding machine, and finally the finished tire is vulcanized in a vulcanizing machine. The three main steps are component production, tire blank molding, and tire blank vulcanization.

[0004] The tire manufacturing processes using casting technology described in patents CN110561979B, CN210591242U, CN110948764B, and CN211364159U have significantly simplified the tire manufacturing process. The process in CN110561979B, in particular, has resulted in substantial reductions in production costs, manufacturing processes, and fixed assets. In actual production, although the overall process is simplified compared to rubber tires, it still involves first forming the tire blank or carcass, then applying rubber and vulcanizing (curing). This patent, based on the aforementioned technologies, develops a tire structure that first applies rubber to individual components and then assembles them, greatly improving production efficiency.

Example

[0032] The tire forming process is described using polyurethane as the outer covering material for each component and employing a casting and coating method.

[0033] Taking tire specification 16.00R25 as an example, this specification requires one tread bearing ring, 36 sidewall supports (18 per side), and one bead connector. The surfaces of the tread bearing ring, sidewall supports, and bead connector are roughened, glue is applied, and they are placed into a casting mold (12 sidewall supports per mold). The mold is then heated at 60°C for 2 hours. After removal, polyurethane material is poured into the mold. After pouring, the mold is placed in an oven at 120°C for 2 hours to cure. The components are then removed from the mold. At this point, the tread, sidewall, and bead components, coated with cast thermosetting polyurethane material, are complete.

[0034] After the rubber-coated components are trimmed, the tire assembly begins. Step 1: Install the 18 rubber-coated sidewall components (one side) one by one onto the tire tread, simultaneously assembling the inner support. The other end is then connected to the bead component via the connecting hole. Step 2: After installation, install the other 18 rubber-coated sidewall components one by one onto the other side of the tire tread, simultaneously installing the inner support on the same side. The other end is then connected to the bead component via the connecting hole. At this point, the tire's basic forming process is complete, and it can be used as a non-pneumatic tire. Step 3: For tires of this specification used in certain harsh or heavy-load scenarios, it is necessary to continue installing the lateral connecting strips to connect multiple adjacent sidewall components.

[0035] Additionally, if it is necessary to increase the load capacity of a single tire, the support capsule can be inserted into the tire chamber at the end of the first step. This component is suitable for use under extremely harsh conditions and high loads.

[0036] At this point, the tire has completed the forming process and can be used as a product.

[0037] It should be noted that, due to the adoption of a new tire structure, the tire specification (16.00R25) selected in this example is only referred to in terms of its external dimensions. Example

[0038] The tire forming process is described using polyurethane as the outer covering material for each component and employing injection molding. Taking tire specification 17.5R25 as an example, this specification has 1 tread bearing ring, 48 sidewall supports (24 per side), and 1 bead ring. The surfaces of the tread bearing ring, sidewall supports, and bead ring are roughened, glue is applied, and they are placed into an injection mold (12 sidewall supports per mold). After removal, the mold is installed on the injection molding machine, and hot water is passed through the mold to heat it to 40°C before injection molding begins. At this point, the tread component, sidewall component, and bead component, coated with thermoplastic polyurethane material, are complete.

[0039] After the rubber-coated components are trimmed, the tire assembly begins. Step 1: Install the 18 rubber-coated sidewall components (one side) one by one onto the tire tread, simultaneously assembling the inner support. The other end is then connected to the bead component via the connecting hole. Step 2: After installation, install the other 18 rubber-coated sidewall components one by one onto the other side of the tire tread, simultaneously installing the inner support. The other end is then connected to the bead component via the connecting hole. At this point, the tire's basic forming process is complete, and it can be used as a non-pneumatic tire. Step 3: For tires used in certain harsh environments or under heavy loads, it is necessary to continue installing the lateral connecting strips to connect adjacent sidewall components.

[0040] Additionally, if it is necessary to increase the load capacity of a single tire, the support capsule can be inserted into the tire chamber at the end of the first step. This assembly method is suitable for use in extremely harsh conditions and high-load situations.

[0041] At this point, the tire has completed the forming process and can be used as a product.

[0042] It should be noted that, due to the adoption of a new tire structure, the tire specification (17.5R25) selected in this example is only referred to in terms of its external dimensions. Example

[0043] The tire forming process is described using rubber as the outer material of each component and employing molding and rubber coating.

[0044] Taking tire specification 29.5R25 as an example, this specification has 1 tread bearing ring, 48 sidewall supports (24 per side), and 1 bead ring. The surfaces of the tread bearing ring, sidewall supports, and bead ring are roughened, glue is applied, and they are heated in an oven at 60℃ for 2 hours. After removal, they are ready to be covered with uncured rubber.

[0045] Using extruded tread compound, wrap it around the bearing ring and press it firmly. After tightening the joint, use rollers to ensure the tread is tightly adhered to the bearing ring. Then, put on a vacuum sleeve and create a vacuum to ensure it adheres completely to the tread compound. Since the bearing ring is rigid, it provides some support. Next, place it in a vulcanizing tank at 140°C for 1 hour to cure. After this, the tread component is fully coated with the compound.

[0046] The process of applying rubber to the bead connecting ring is the same as the process of applying rubber to the tread.

[0047] Rubber strips are wrapped around the surface of the tire sidewall support and placed into a rubber mold. A flat vulcanizing machine is used to apply pressure of 1.8 MPa. A small amount of rubber overflows from the overflow port of the mold under pressure. The vulcanization temperature is 160℃ and the vulcanization time is 25 minutes. After vulcanization, the tire can be removed.

[0048] At this point, the tread and bead components, which are wrapped in rubber material, are manufactured using a vacuum molding process; and the sidewall components, which are wrapped in rubber material, are manufactured using a molding process.

[0049] After the rubber-coated components are trimmed, the tire assembly begins. Step 1: Install the 24 rubber-coated sidewall components (one side) one by one onto the tire tread, simultaneously assembling the inner support. The other end is then connected to the bead component via the connecting hole. Step 2: After installation, install the other 24 rubber-coated sidewall components one by one onto the other side of the tire tread, simultaneously installing the inner support. The other end is then connected to the bead component via the connecting hole. At this point, the tire's basic forming process is complete, and it can be used as a non-pneumatic tire. Step 3: For tires used in certain demanding applications, it is necessary to continue installing the lateral connecting strips to connect adjacent sidewall components.

[0050] Additionally, if it is necessary to increase the load capacity of a single tire, the support capsule can be inserted into the tire chamber at the end of the first step. This assembly method is suitable for use in extremely harsh conditions and high-load situations.

[0051] At this point, the tire has completed the forming process and can be used as a product.

[0052] It should be noted that, due to the adoption of a new tire structure, the tire specification (29.5R25) selected in this example is only referred to in terms of its external dimensions. Example

[0053] The tire forming process is described, with the tread made of rubber and molded and coated; other components are wrapped with polyurethane and cast.

[0054] Taking tire specification 27.00R49 as an example, this specification has 1 tread bearing ring, 64 sidewall supports (32 per side), and 1 bead connector. The surfaces of the tread bearing ring, sidewall supports, and bead connector are roughened and then glued.

[0055] Extruded tread compound is pressed around the bearing ring and then tightened. Rollers are used to ensure the tread and bearing ring are tightly bonded. A vacuum sleeve is then fitted, and a vacuum is created to ensure it adheres completely to the tread compound. The bearing ring's inherent rigidity provides support. The tire is then placed in a vulcanizing tank at 140°C for 1 hour. After this, the tread component is fully coated with the compound.

[0056] Place the sidewall support and bead connector into the support casting mold (8 pieces per mold) and the bead connector casting mold, respectively, and preheat them to 60°C in an oven. Pour the corresponding polyurethane material into the molds. After pouring, place them in an oven at 120°C for 2 hours to cure. After curing, remove the parts from the molds.

[0057] At this point, the tread component made of rubber molding material, the sidewall component made of cast polyurethane material, and the bead connector component made of cast polyurethane material are completed.

[0058] After the rubber-coated components are trimmed, the tire assembly begins. Step 1: Install the 24 rubber-coated sidewall components (one side) one by one onto the tire tread, simultaneously assembling the inner support. The other end is then connected to the bead component via the connecting hole. Step 2: After installation, install the other 24 rubber-coated sidewall components one by one onto the other side of the tire tread, simultaneously installing the inner support. The other end is then connected to the bead component via the connecting hole. At this point, the tire's basic forming process is complete, and it can be used as a non-pneumatic tire. Step 3: For tires used in certain demanding applications, it is necessary to continue installing the lateral connecting strips to connect adjacent sidewall components.

[0059] Additionally, if it is necessary to increase the load capacity of a single tire, the support capsule can be inserted into the tire chamber at the end of the first step. This assembly method is suitable for use in extremely harsh conditions and high-load situations.

[0060] At this point, the tire has completed the forming process and can be used as a product.

[0061] It should be noted that, due to the adoption of a new tire structure, the tire specification (27.00R49) selected in this example is only referred to in terms of its external dimensions. Example

[0062] The tire forming process is described, using rubber as the tread material and employing winding and molding vulcanization; other components are made of polyurethane and are formed by casting.

[0063] Taking tire specification 33.00R51 as an example, this specification has 1 tread bearing ring, 56 sidewall supports (28 per side), and 1 bead connector. The surfaces of the tread bearing ring, sidewall supports, and bead connector are roughened and then glued.

[0064] Extruded tread strips, 3.5 cm wide and 3 mm thick, are wound around the bearing ring, tightening during the winding process until a thickness of 8 cm is reached. The strips are then placed into a movable mold. The vulcanizing machine has a central support device; after the tread blocks are pressed together, the central device expands outward, holding the bearing ring in place internally. After this process, the temperature is raised to 150°C, and vulcanization is completed after 1 hour. At this point, the tread components are fully coated with rubber.

[0065] Place the sidewall support and the bead connector into the support casting mold (7 pieces per mold) and the bead connector casting mold, respectively, and preheat them to 60°C in an oven. Pour the corresponding polyurethane material into the molds. After pouring, place them in an oven at 120°C for 2 hours to cure. After curing, remove the parts from the molds.

[0066] At this point, the tread component made of wound rubber material, the sidewall component made of cast polyurethane material, and the bead connection ring component are completed.

[0067] After the rubber-coated components are trimmed, the tire assembly begins. Step 1: Install the 24 rubber-coated sidewall components (one side) one by one onto the tire tread, simultaneously assembling the inner support. The other end is then connected to the bead component via the connecting hole. Step 2: After installation, install the other 24 rubber-coated sidewall components one by one onto the other side of the tire tread, simultaneously installing the inner support. The other end is then connected to the bead component via the connecting hole. At this point, the tire's basic forming process is complete, and it can be used as a non-pneumatic tire.

[0074] Rubber is wrapped around the surface of the tire sidewall support and placed into a rubber mold. A flat vulcanizing machine is used to apply pressure of 1.8 MPa. A small amount of rubber overflows from the overflow port of the mold under pressure. The vulcanization temperature is 160℃ and the vulcanization time is 25 minutes. After vulcanization, it can be taken out.

[0075] Extruded rubber is pressed around the connecting ring and then tightened. A roller is used to ensure the rubber adheres tightly to the connecting ring. Afterward, a vacuum sleeve is fitted, and a vacuum is created to ensure the sleeve is fully adhered to the tread rubber. The inherent rigidity of the connecting ring provides support. The tire is then placed in a vulcanizing tank at 140°C for 1 hour. After this, the connecting ring assembly is fully coated with rubber.

[0076] At this point, the tread components made with cast polyurethane material, the sidewall components made with molded rubber material, and the connecting ring components made with vacuum molded rubber material are completed.

[0077] After the rubber-coated components are trimmed, the tire assembly begins. Step 1: Install the 28 rubber-coated sidewall components (one side) one by one onto the tire tread, simultaneously assembling the inner support.
