Description

Technical Field

[0001] The invention relates to a tire, in particular to a heavy-duty special tire and a preparation method thereof. Background Art

[0002] Among existing tire technologies, PU wheels are widely used in various vehicles and equipment due to their wear resistance. However, despite their excellent performance in wear resistance, PU wheels have obvious deficiencies in other aspects. These deficiencies include:

[0003] PU wheels are usually heavy, which increases the overall weight of the vehicle and has a negative impact on fuel efficiency and power output.

[0004] PU wheels have poor anti-skid performance when encountering water or slippery surfaces, which can cause sliding and difficulty in control, thereby increasing the risk of accidents.

[0005] PU wheels will generate relatively loud noise when running, which not only affects driving comfort but may also cause interference to the surrounding environment.

[0006] Due to these shortcomings, the performance of traditional PU wheels is limited in some key applications. For example, in logistics transfer vehicles, robot wheels, engineering wheels, transport wheels and other occasions that require high maneuverability and silent operation, these defects of PU wheels may lead to reduced efficiency and increased safety risks.

[0007] In addition, with the development of technology, the demand for tire performance is also increasing, especially in terms of super load-bearing capacity, comfort, and tire weight. These requirements have prompted tire manufacturers and R&D teams to look for new tire designs that can solve the above problems.

[0008] Therefore, there is an urgent need to develop a new type of tire that not only has excellent wear resistance, but also solves the problems of weight, anti-skid performance and noise, and can also adapt to a wider range of application scenarios, such as electric vehicles, bicycles, tricycles, wheelchairs, elderly scooters and scooters, etc. This new type of tire will greatly improve the overall performance and safety of vehicles and equipment, and meet the needs of modern transportation and industry for efficient and safe tires. Summary of the invention

[0009] In order to solve the above problems, the present invention provides a heavy-duty special tire and a preparation method thereof, which can effectively solve the deficiencies in the prior art.

[0010] The present invention is realized by the following technical scheme: a heavy-duty special tire, comprising:

[0011] An elastic wrapping layer, wherein the elastic wrapping layer has at least one hollow cavity for filling an elastic metal piece, and the elastic wrapping layer serves as an external elastic support;

[0012] At least one group of elastic metal parts is installed in at least one hollow cavity of the elastic wrapping layer, and is used for internal elastic support of the entire elastic wrapping layer.

[0013] Furthermore, the elastic metal part is made of any metal material with elasticity or a super carbon fiber composite material.

[0014] Furthermore, the hollow cavity is in a ring shape, and the elastic metal piece adopts a ring structure matching the hollow cavity.

[0015] Furthermore, the elastic metal piece is an annular metal spring, and the inner and outer diameters of the metal spring are adapted to the hollow cavity.

[0016] Furthermore, the elastic wrapping layer and the elastic metal part form a composite tire body.

[0017] Furthermore, the elastic wrapping layer is made of elastic rubber material or elastic composite material.

[0018] A method for manufacturing a heavy-duty special tire of the present invention comprises the following steps:

[0019] a) preparing an elastic wrapping layer material, selecting an elastic rubber material or an elastic composite material, and processing it into a tire shape, wherein the elastic wrapping layer has at least one preset hollow cavity;

[0020] b) manufacturing elastic metal parts, selecting metal materials with elasticity, and processing them into matching annular structures according to the size and shape of the hollow cavity;

[0021] c) installing the manufactured elastic metal part into the hollow cavity of the elastic wrapping layer to ensure precise fit between the metal part and the hollow cavity;

[0022] d) Assembling the elastic wrapping layer and the elastic metal part into a whole to form a composite tire body, ensuring uniformity and stability of the entire structure;

[0023] e) Conduct quality inspection on tires, including testing the elasticity of the elastic wrapping layer, the installation stability of the elastic metal parts and the effectiveness of the anti-skid patch, to ensure that the tires meet the design standards and safety requirements.

[0024] The beneficial effects of the present invention are:

[0025] The invention solves the problems of the traditional solid tire being heavy, poor in elasticity, and poor in comfort, and at the same time has the advantages of being puncture-proof and free from tire blowout.

[0026] The present invention is a non-pneumatic tire, which solves the problems of traditional pneumatic tires and vacuum tires such as puncture, air leakage, etc.

[0027] The internal elastic parts (including various metal and composite materials, etc.) of the present invention have not only conventional circular shapes, but also special-shaped elastic parts designed in combination with specific tire structures, including but not limited to circular, trapezoidal, fan-shaped, arc-shaped, wavy, cross-shaped, conical, etc.;

[0028] The present invention can greatly improve the load-bearing capacity of the tire, and the elastic material and built-in elastic accessories can greatly improve the comfort and safety of the tire;

[0029] The tire surface material of the present invention is fully combined with the built-in elastic parts through a special process, and has strong stability and high safety factor;

[0030] The present invention solves many problems of traditional heavy-duty PU wheels, such as noise, strong vibration, no shock absorption effect, unsuitability for fast advancement, extremely poor anti-skid effect, great damage to the ground, large resistance, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It also includes an elastic metal piece 5, which is installed in the hollow cavity 4 of the elastic wrapping layer 1 and is used for internal elastic support of the entire elastic wrapping layer 1. The number of elastic metal pieces 5 depends on the volume of the elastic metal pieces 5 and the number of hollow cavities 4.

The latest design dimension is that the metal spring matches the inner diameter of the hollow cavity 4 to reduce the gap and fit perfectly. The structural design of the elastic metal part 5 can be expanded to various shapes, including but not limited to circular, rectangular, arc, fan-shaped, triangular, pentagonal, serrated, plum blossom, conical, trapezoidal, gear-shaped, barbed, etc.
