Description

Technical Field

[0001] This invention belongs to the technical field of belt structure for agricultural radial tires, specifically a novel belt structure for agricultural radial tires. Background Technology

[0002] Currently, agricultural tire belt layer structure consists of four belt layers of equal width bonded together, with four layers of polyester cord arranged in a cross pattern. Because agricultural tires are usually used continuously during the spring plowing and autumn harvest seasons, and the road conditions are often uneven, the tires are not on the same horizontal axis for a long time (plowing on or off the bank). The tires need to maintain high traction while also maintaining high torsional deformation of the tread and shoulder. During driving, the shear force and stress at the ends of every two connected belt layers are too concentrated, which can easily cause premature delamination and affect the service life of the tire. Summary of the Invention

[0003] The purpose of this invention is to provide an agricultural radial tire belt structure to solve the problems mentioned in the background art.

[0004] To address the above problems, this invention provides a technical solution for an agricultural radial tire belt structure:

[0005] The belt structure of an agricultural radial tire includes belt layer one, belt layer two, belt layer three, belt layer four, gasket one, gasket two, rubber ring, steel wire ring, leak-proof ring, metal strip, and through hole. Belt layer two is disposed on belt layer one, belt layer three is disposed on belt layer two, and belt layer four is disposed on belt layer three. Gasket one is disposed on belt layer two, and gasket two is disposed on belt layer four. Rubber rings are fixedly connected to both belt layer one and belt layer three. Steel wire rings are disposed inside the rubber rings. Through hole is opened on the rubber rings. Leak-proof rings are fixedly connected to both belt layer one and belt layer three. Metal strip is disposed inside the leak-proof ring.

[0006] Preferably, the width of the first belt layer and the third belt layer are the same, and the width of the second belt layer and the fourth belt layer are the same. Different widths can make the belt layers bear force evenly.

[0007] Preferably, the first pad is fixedly connected to the first belt layer, the first pad is fixedly connected to the third belt layer, the first pad is fixedly connected to the rubber ring, and the first belt layer can be wrapped around the second belt layer by the first pad.

[0008] Preferably, the second pad is fixedly connected to the third belt layer, and the second pad is fixedly connected to the rubber ring. The second belt layer can wrap around the fourth belt layer through the second pad.

[0009] Preferably, there are multiple steel wire rings, which are evenly distributed inside the rubber ring, and the steel wire rings can protect the second belt layer and the belt layer.

[0010] Preferably, the leak-proof ring is fixedly connected to the rubber ring, and the leak-proof ring is made of rubber material, which has good elasticity.

[0011] Preferably, there are multiple through holes, which are evenly distributed on the rubber ring. Multiple through holes can increase the elasticity of the rubber ring.

[0012] Preferably, there are multiple metal strips, which are evenly distributed inside the leak-proof ring. The metal strips can prevent the steel wires in the belt layer from puncturing the tire.

[0013] The beneficial effects of this invention are as follows: This invention relates to an agricultural radial tire belt structure, which has the characteristics of improving the deformation resistance of the tread and shoulder portions and the shear resistance between belt layers, and effectively balancing the stress distribution at the ends of the belt layers. In specific applications, compared with traditional agricultural radial tire belt structures, this agricultural radial tire belt structure has the following beneficial effects:

[0014] By wrapping belt layer one with belt layer two and belt layer three with belt layer four, the shear force between each layer is reduced, thereby improving the deformation resistance of the tread and shoulder, as well as the shear force between belt layers. This effectively balances the stress distribution at the ends of the belt layers, and the rubber rings and leak-proof rings prevent the steel wires inside the belt layer from puncturing after deformation.

[0018] like Figure 1 As shown, the specific implementation adopts the following technical solution: Example

[0019] The belt structure of an agricultural radial tire includes belt layer 1, belt layer 2, belt layer 3, belt layer 4, gasket 1 5, gasket 2 6, rubber ring 7, steel wire ring 8, leak-proof ring 9, metal strip 10, and through hole 11. Belt layer 2 is disposed on belt layer 1, belt layer 3 is disposed on belt layer 2, belt layer 4 is disposed on belt layer 3, gasket 5 is disposed on belt layer 2, and gasket 2 6 is disposed on belt layer 4. Rubber rings 7 are fixedly connected to both belt layer 1 and belt layer 3. Steel wire rings 8 are disposed inside the rubber rings 7. Through hole 11 is opened on the rubber rings 7. Leak-proof rings 9 are fixedly connected to both belt layer 1 and belt layer 3. Metal strip 10 is disposed inside the leak-proof ring 9.

[0020] Among them, the width of the first belt layer 1 is the same as that of the third belt layer 3, and the width of the second belt layer 2 is the same as that of the fourth belt layer 4. Different widths can make the belt layers be subjected to uniform stress.

[0021] Among them, the first pad 5 is fixedly connected to the first belt layer 1, the first pad 5 is fixedly connected to the third belt layer 3, the first pad 5 is fixedly connected to the rubber ring 7, and the first belt layer 1 can wrap the second belt layer 2 with the first pad 5.

[0022] Among them, the second pad 6 is fixedly connected to the third belt layer 3, the second pad 6 is fixedly connected to the rubber ring 7, and the second belt layer 2 can wrap the fourth belt layer 4 with the second pad 6.

[0023] The number of steel wire rings 8 is multiple, and the multiple steel wire rings 8 are evenly distributed inside the rubber ring 7. The steel wire rings 8 can protect the second belt layer 2 and the fourth belt layer 4.

[0024] The leak-proof ring 9 is fixedly connected to the rubber ring 7. The leak-proof ring 9 is made of rubber material, which has good elasticity.

[0025] The number of through holes 11 is multiple, and the multiple through holes 11 are evenly distributed on the rubber ring 7. The multiple through holes 11 can increase the elasticity of the rubber ring 7.

[0026] The metal strips 10 are multiple and are evenly distributed inside the leak-proof ring 9. The metal strips 10 can prevent the steel wires in the belt layer from being punctured by the tire.

[0027] The invention is used in the following manner: by wrapping belt layer 1 around belt layer 2 and belt layer 3 around belt layer 4, the shear force between each layer is reduced, thereby improving the deformation resistance of the tread and shoulder, as well as the shear resistance between belt layers, effectively balancing the stress distribution at the ends of the belt layers. Furthermore, the steel wire ring 8 inside the rubber ring 7 and the metal strip 10 inside the anti-leak ring 9 prevent the steel wires inside the belt layer from puncturing the tire after deformation, thus preventing the steel wires of the belt layer from puncturing the tire and causing a blowout after the tire is damaged.
