[0017] The support structure is bent and deformed to form an arc that adapts to the tire carcass skeleton to support the tire radially.

[0018] Furthermore, the rim body components are machined with rim body functional holes.

[0019] Furthermore, the spoke components are configured as tapered plate structures with a width that gradually decreases from one end near the rim body component to the end away from the rim body component; the number of spoke components can be single or multiple, and they are arranged discontinuously after being formed in one process;

[0020] The spoke components are machined with spoke connection holes, and the spokes are connected to the axle through the spoke connection holes to transmit the power of the axle to the tires;

[0021] The spoke assembly is configured with an arcuate surface at the end away from the rim body assembly, and the arcuate surfaces of multiple spoke assemblies form a spoke center hole for accommodating the axle.

[0022] Furthermore, the rim body after the skeleton is bent and formed has a centrally symmetrical structure, and its external shape is circular, polygonal, or irregular.

[0051] See Figures 1 to 14 As shown;

[0052] This embodiment discloses a frame having a rim and spokes, the frame comprising:

[0053] Matrix 3;

[0054] Support structure 4 symmetrically arranged along the width direction of base 3; and

[0055] The rim body component 2 is connected to the end of the support structure 4 away from the base 3. The rim body component 2 is symmetrically arranged, and multiple rim body component 2 are connected to each other to form the rim body 6 of the tire skeleton.

[0056] At least one side of the rim body component 2 is connected to the spoke component 1, and multiple spoke components 1 are bent and connected to each other to form the spoke 5 of the tire skeleton.

[0057] In this embodiment, the substrate 3 is processed with substrate functional holes 301 and substrate connection ports 302; the substrate 3 is connected to external components through the substrate connection ports 302, wherein the substrate functional holes 301 can enhance the bonding force between the substrate 3 and the adhesive.

[0058] In this embodiment, the support structure 4 is configured as a tapered plate structure with a width that gradually decreases from one end near the base 3 to the other end away from the base 3; the support structure 4 is machined with support structure functional holes 401; the support structure 4 is bent and deformed to form an arc that adapts to the tire carcass skeleton to support the tire radially, providing the tire with load-bearing, cushioning and torsional performance.

[0059] In this embodiment, the rim body component 2 is machined with a rim body functional hole 201. The rim body functional hole 201 is used to increase the bonding force between the rim body 6 and the rubber material, thereby improving the power transmission efficiency.

[0060] In this embodiment, the spoke component 1 is configured as a tapered plate structure with a width that gradually decreases from one end near the rim body component 2 to the end away from the rim body component 2; the number of spoke components 1 can be single or multiple, and they are arranged discontinuously after being formed in one process.

[0061] The spoke component 1 is machined with spoke connection holes 101, and the spoke 5 is connected to the axle through the spoke connection holes 101 to transmit the power of the axle to the tire;

[0062] The end of the spoke assembly 1 away from the rim body assembly 2 is configured as an arc surface 102, and the arc surfaces 102 of multiple spoke assemblies 1 form a spoke center hole 7 for accommodating the axle.

[0063] The rim body 6 after the skeleton is bent and formed has a centrally symmetrical structure, and its external shape can be circular, polygonal, or irregular.

[0064] Specifically, this embodiment discloses a tire carcass structure. This tire carcass is formed in one piece and mainly consists of a spoke component 1, a rim body component 2, a base 3, and a support structure 4. It can directly form a tire carcass with spokes 5 and a rim body 6. In this embodiment, the spoke component 1 is located on the outermost side of the carcass and forms the spokes 5 after bending and connecting. A connecting hole 101 runs through the spoke component 1, and the end that mates with the axle has an arc-shaped surface 102, thereby achieving connection and adaptation with the axle. In this embodiment, the rim body component 2 is connected to the aforementioned spoke component 1 on one side and to the support structure 4 on the other side. After deformation, it is connected to form the rim body 6. The rim body component 2 has a through-hole 201. The base 3 is machined with a base functional hole 301 and a base connection port 302.

The vertical axis is then connected to the mold, and the mold rotates around the vertical axis to complete the casting of other parts.

[0085] S17. Place the cast tire into an oven to cure.

[0086] S18. After curing, the product is demolded to obtain the finished tire.

[0087] The tire manufacturing process using this carcass is simplified and costs are reduced. The method of using the carcass is described using a tire cast from liquid polyurethane material as an example.

[0089] Example 1;

[0090] Taking tire size 33.00R51 as an example, the usage method of this carcass is introduced as follows:

[0091] First, stamping produces the spoke component 1, the rim body component 2, the base 3, and the support structure 4 (such as...). Figure 1 Secondly, the two spoke components 1 are bent to maintain a specific position with the rim body component 2 (e.g., Figure 3 Then the substrate 3 is rolled into a cylindrical shape (such as...). Figure 4 Next, the support structure 4 is bent into the carcass frame curvature, and the rim body component 2 is bent to a suitable curvature. The frame is then placed in a heat treatment furnace at 830℃, resulting in a workpiece hardness of HRC40-45. After removal, the frame surface is degreased, derusted, and the oxide coating is removed. The rim body component 2 is welded axially and circumferentially, while the spoke components 1 on both sides are connected axially and circumferentially (e.g., ...).

Figure 7 After correcting the roundness of the formed skeleton, place it in a drying oven, control the humidity at 10% to 30% RH to prevent surface corrosion, and finally apply glue to the whole thing and dry it for 2 hours.

The rim body component 2 is bent to a suitable arc. The skeleton is placed in a heat treatment furnace at a temperature of 830℃. The hardness of the treated workpiece is HRC40-45. After removal, the surface of the skeleton is degreased, derusted, and the oxide coating is removed. The rim body component 2 is welded axially and circumferentially, while the single-sided spoke component 1 is connected axially and circumferentially by welding.
