Description

Technical Field

[0001] The utility model relates to a tire, in particular to a solid tire made of recycled carbon black. Background Art

[0002] With the improvement of people's living standards and the development of automobile industry and tire manufacturing industry, a large number of waste rubber tires are generated every year. These tires cannot be simply incinerated or discarded. Such treatment methods not only cause environmental pollution problems, but are also a waste. We need to reuse the carbon black recovered from waste rubber tires.

[0003] Many leading companies in this field have begun to add recycled carbon black to tire products as a circular reinforcing carbon black for tires. In this context, we respond to industry trends and provide a solid tire made of recycled carbon black to seize the market.

[0004] The inner layer of existing tires with recycled carbon black is usually a laminated structure. The advantage of the laminated structure is that it increases the load-bearing capacity of the tire, but there is no air inside the solid tire, so its load-bearing capacity is naturally higher than that of ordinary pneumatic tires; the disadvantage of the laminated structure is that the comfort will be reduced, and because the solid tire itself is not as comfortable as the pneumatic tire, the solid tire made with the laminated structure is even less comfortable and has a strong sense of vibration when driving.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The present embodiment is about a solid tire made of recycled carbon black, including a tread ring 1 located at the outermost circle in contact with the ground, a coaxial hub 2 is provided on the radial inner side of the tread ring 1 and the two are connected by a plurality of spokes 3, and the connection method of the tread ring 1, the hub 2 and the spokes 3 is the prior art, which is not limited to the embodiments of the present application and is hereby explained.

[0023] The tread ring 1 of the present embodiment includes a tread rubber 4, that is, the tread ring 1 as a whole is tread rubber 4, the inner lining of the tread rubber 4 has a plurality of recycled carbon black blocks 7 and a plurality of cord blocks 9, and the two together form a circle layer, and the plurality of recycled carbon black blocks 7 and the plurality of cord blocks 9 are arranged in a manner of being alternately connected to each other in sequence. It can be understood that both sides of a single recycled carbon black block 7 are cord blocks 9, and correspondingly, both sides of a single cord block 9 are also recycled carbon black blocks 7. The connection between the recycled carbon black block 7 and the cord block 9 can be chloroprene, silicone rubber, etc., which are the same rubber elastomers known to those skilled in the art, and the present application is not limited thereto, and hereby explains; a steel belt bundle 8 is wound on the surface of the recycled carbon black block 7, and a shear rubber column 11 is provided in the cord block 9; the winding of the steel belt bundle 8 strengthens the ability of the recycled carbon black block 7 to provide good support and stability for the tread rubber 4.

[0024] Preferably, the spokes 3 are in a sheet-like structure and are multiple in number.

[0025] The ring layer composed of several recycled carbon black blocks 7 and several cord blocks 9 is formed in a manner of being divided into a contact surface side 5 and a connection surface side 6 in the thickness of the tread ring 1. It can be understood that the recycled carbon black blocks 7 and the cord blocks 9 are wrapped in the tread rubber 4, and the tread rubber 4 is divided into two parts: the contact surface side 5 and the connection surface side 6.

[0026] Preferably, the contact surface side 5 is the outer ring portion of the thickness of the tread ring 1, that is, the outer ring portion of the tread rubber 4. Therefore, a tire pattern (not shown in the figure) is provided on the surface of the contact surface side 5 and the tread ring 1. The tire pattern is not a technical feature that needs to be protected in this application; the connection surface side 6 is the inner ring portion of the thickness of the tread ring 1.

[0027] Furthermore, the maximum thickness of the contact surface side 5 is greater than the maximum thickness of the connection surface side 6. Since the surface of the tread ring 1 needs to be provided with a tire pattern that penetrates into the contact surface side 5, the thickness of the contact surface side 5 needs to be increased to prevent the cutting of the pattern from damaging the structure of the recycled carbon black block 7 and the cord block 9, and at the same time, it is beneficial to enhance the wear resistance; the connection surface side 6 is actually for the convenience of connecting the inner ring surface of the tread ring 1 with the spoke 3, and at the same time, the connection surface side 6 also provides protection for the recycled carbon black block 7 and the cord block 9.

[0028] The maximum extension lengths of the recycled carbon black block 7 and the cord block 9 in the tire width are the same and do not exceed the sidewall surface of the tread ring 1. Similarly, the recycled carbon black block 7 and the cord block 9 are included in the tread rubber 4 through structural settings to enhance the wear resistance of the tire.

[0029] A plurality of holes 10 are provided on the cord block 9, and shear rubber columns 11 are filled in the holes 10. The holes 10 are arranged toward the contact surface side 5. The cord block 9 in this embodiment is used to provide tensile strength and elasticity. The elasticity can be understood as providing anti-vibration comfort for the tire and is used to reduce the rolling resistance of the tire during driving. In order to prevent the driving parameters between the cord block 9 and the recycled carbon black block 7 from being too different, the difference is compensated by filling the cord block 9 with shear rubber columns 11.

[0030] In this way, the solid tire made of recycled carbon black disclosed by the utility model replaces the traditional stacked structure by arranging the internal block structure to form a ring layer. Compared with the traditional stacked structure, the number of vibration transmission layers is smaller, which ensures the road feel while being more comfortable. The recycled carbon black blocks 7 are filled inside the tire to achieve the purpose of environmentally friendly recycling of recycled carbon black and save costs. The recycled carbon black blocks 7 are organically combined with the cord blocks 9 to improve the tire's performance in terms of comfort, vibration resistance, and wear resistance.

[0031] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
