Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire manufacturing technology, specifically a modular tire. Background Technology
[0002] During tire use, pneumatic tires mainly rely on internal air pressure to maintain their shape and performance. Their inner and outer layer design can reduce manufacturing and maintenance costs. However, once the tread is punctured by a sharp object, it can lead to air leakage or instantaneous blowout, affecting use and resulting in a high maintenance rate. Solid tires, on the other hand, are widely used in special working conditions such as ports and mines due to their advantages of not requiring inflation and being less prone to blowouts. However, existing solid tires have many problems. On the one hand, solid tires generate a lot of heat during use due to friction, and traditional solid tires have poor heat dissipation performance. Excessive temperature can lead to a decline in tire material performance and shorten tire life. On the other hand, the fixed structure of solid tires often requires replacement of the entire tire if partial damage occurs, resulting in high maintenance costs. Therefore, a modular tire is proposed. Summary of the Invention
[0003] The purpose of this invention is to propose a modular tire to solve the above problems.
[0004] To achieve the above objectives, the following technical solution is provided: a modular tire, comprising a solid outer tire body mounted on a wheel, characterized in that: it further comprises an airless inner tube with air ducts mounted inside the outer tire body; the airless inner tube is circumferentially spliced from several modules with complementary shapes, and the airless inner tube is provided with a ventilation system for reducing the temperature of the outer tire body.
[0005] As a preferred embodiment, the ventilation system provided on the pneumatic inner tube includes at least one module with a vent that communicates with the outside, and several air ducts provided within the module and communicating with the vent.
[0006] Preferably, each module has at least one side with a second ventilation opening that communicates with the air duct and the first ventilation opening.
[0007] Preferably, a double-sided ventilation gap is formed between the pneumatic inner tube and the outer tire body, and the double-sided ventilation gap is connected to the air duct and the first ventilation opening through the second ventilation opening.
[0008] Preferably, it also includes an annular support pad disposed between the outer tire body and the pneumatic inner tube to support the outer tire body and facilitate the installation and removal of the pneumatic inner tube.
[0009] Preferably, the annular support pad is provided with a third ventilation opening that communicates with the second ventilation opening.
[0010] Preferably, at least one module of the pneumatic inner tube has a positioning boss on its outer circumferential surface.
[0011] Preferably, the annular support pad is provided with a positioning groove that matches the positioning boss.
[0012] Preferably, the module has mating surfaces at both ends.
[0013] Preferably, the wheels are provided with air inlets and outlets that are connected to the ventilation openings.
[0014] The beneficial effects of this utility model are as follows: By setting up modules, they can be flexibly assembled and disassembled according to actual needs. When a module is damaged, only the damaged module needs to be replaced, without replacing the entire tire, which greatly reduces maintenance costs and improves resource utilization. By setting up a ventilation system, the risk of tire performance degradation due to high temperature is effectively reduced, and the tire service life is extended.
[0015] The module is cooled by the combined action of the air duct and the ventilation port. Then, the module comes into contact with the outer tire body, and the low temperature module absorbs the high temperature of the outer tire body, thereby reducing the temperature of the outer tire body and preventing the performance of the outer tire body from deteriorating due to high temperature, thus increasing the service life of the outer tire body.
[0016] The air duct, vent one, and vent two are interconnected to form a complete ventilation and heat dissipation network, like a traffic hub. Connecting the various vents, it plans the orderly flow path of cold air in the air duct, ensuring that the cold air can smoothly reach all parts of the inner wall of the tire, achieving comprehensive and efficient heat dissipation and avoiding uneven heat dissipation in some areas. At the same time, the air duct also provides a certain degree of support and stability to the structure of the pneumatic inner tube, helps to disperse the pressure from the outer tire body, increases the overall structural strength of the tire, ensures stable operation of the tire under various working conditions, and also saves raw materials and production energy consumption, reducing production costs.
[0017] The ring-shaped support pad expands the inner cavity of the tire body during the installation of the airless inner tube, facilitating installation and improving efficiency. The positioning boss and positioning groove accurately determine the position of the airless inner tube on the ring-shaped support pad, ensuring the connection between vent two and vent three, while also preventing the airless inner tube from shifting during tire operation and affecting the heat dissipation of the tire body.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] Example 1: Participation in Appendix Figure 1-2As shown, this embodiment of a modular tire includes a solid outer tire body 1 mounted on a wheel. Its key feature is that it also includes an airless inner tube 2 with air ducts mounted inside the outer tire body 1. The airless inner tube 2 is circumferentially assembled from several modules 21 with complementary shapes. The airless inner tube 2 is equipped with a ventilation system 3 for reducing the temperature of the outer tire body 1. Through the arrangement of the modules 21, flexible assembly and disassembly can be performed according to actual needs. When a module 21 is damaged, only the damaged module 21 needs to be replaced, without replacing the entire tire, greatly reducing maintenance costs and improving resource utilization. The ventilation system 3 effectively reduces the risk of tire performance degradation due to high temperatures, extending tire lifespan.
[0031] In one embodiment, the ventilation system 3 on the pneumatic inner tube 2 includes at least one module 21 with a vent 31 communicating with the outside, and an air duct 32 disposed within the module 21 and communicating with the vent 31. During vehicle operation, the outer tire 1 generates high temperature due to friction with the ground, and the temperature on the outer tire 1 is transferred to the module 21 through contact, causing the temperature of the module 21 to rise. At the same time, cold air enters the air duct 32 through the vent 31, and the module 21 cools down after contacting the cold air. The module 21 contacts the inner wall of the outer tire body 1 and absorbs the heat from the outer tire body 1, thereby reducing the temperature of the outer tire body 1. Moreover, the heat from the outer tire body 1 can be expelled from the air duct 32 through vibration and compression of the air duct 32 through the vent 31. Through the synergistic effect of the air duct 32 and the vent 31, the module 21 is cooled down. Then, through the contact between the module 21 and the outer tire body 1, the low-temperature module 21 absorbs the high temperature of the outer tire body 1, thereby reducing the temperature of the outer tire body 1, preventing the performance of the outer tire body 1 from deteriorating due to high temperature, and increasing the service life of the outer tire body 1.
[0032] In one embodiment, each module 21 has at least one side equipped with a second ventilation port 33 that communicates with the air duct 32 and the first ventilation port 31. When the second ventilation port 33 is provided on the module 21, the cold air entering the air duct 32 can also be directly guided to the inside of the tire body 1 through the second ventilation port 33, thereby directly cooling the tire body 1. At the same time, the heat in the tire body 1 can be expelled from the air duct 32 through the vibration of the wheel, causing the hot air to be discharged from the first ventilation port 31. The alternating hot and cold cycles cool the tire body 1. The 33 ducts are interconnected, forming a complete ventilation and heat dissipation network. Like a transportation hub, they connect the various vents and plan the path for the orderly flow of cold air in the air ducts 32. This ensures that the cold air can reach all parts of the inner wall of the outer tire body 1 smoothly, achieving comprehensive and efficient heat dissipation and avoiding uneven local heat dissipation. At the same time, the air ducts 32 also provide a certain degree of support and stability for the structure of the pneumatic inner tube 2, helping to disperse the pressure from the outer tire body 1, increasing the overall structural strength of the tire, ensuring stable operation of the tire under various working conditions, and saving the use of raw materials and production energy consumption, thus reducing production costs.
[0033] In one embodiment, a double-sided ventilation gap 4 is formed between the pneumatic inner tube 2 and the outer tire body 1. The double-sided ventilation gap 4 is connected to the air duct 32 and the first ventilation opening 31 through the second ventilation opening 33. Cold air flows into the double-sided ventilation gap 4 through the second ventilation opening 33. By setting the double-sided ventilation gap 4, the contact area between the inner wall of the outer tire body 1 and the cold air is increased, so that the cold air can more fully remove the heat on the outer tire body 1, improve the heat dissipation effect, extend the service life of the tire, and at the same time save the amount of raw materials used in the module 21 and reduce the manufacturing cost of the pneumatic inner tube 2.
[0034] Example 2: Participation in Appendix Figure 6-8As shown, it also includes an annular support pad 5 disposed between the outer tire body 1 and the airless inner tube 2 to support the outer tire body 1 and facilitate the installation and removal of the airless inner tube 2; the annular support pad 5 is provided with a third ventilation port 52 connected to the second ventilation port 33; at least one module 21 of the airless inner tube 2 is provided with a positioning boss 22 on its outer circumferential surface; the annular support pad 5 is provided with a positioning groove 51 adapted to the positioning boss 22; during assembly, the annular support pad 5 is first installed on the inner wall of the outer tire body 1, and the inner wall of the outer tire body 1 is opened by the annular support pad 5, so that the airless inner tube 2 can be quickly installed into the outer tire body 1. At the same time, when installing the airless inner tube 2, the module 21 with the positioning boss 22 is first installed on the outer tire body 1. On the annular support pad 5, the positioning boss 22 on the module 21 needs to be inserted into the positioning groove 51 on the annular support pad 5, and then the remaining modules 21 are spliced along the splicing surface 211 of the installed modules 21 to form the airless inner tube 2; through the setting of the annular support pad 5, when installing the airless inner tube 2, the annular support pad 5 can open the inner cavity of the outer tire body 1, which facilitates the installation of the airless inner tube 2 and improves the installation efficiency; through the setting of the positioning boss 22 and the positioning groove 51, the position of the airless inner tube 2 on the annular support pad 5 is accurately determined, ensuring the connection between the second ventilation port 33 and the third ventilation port 52, and at the same time preventing the airless inner tube 2 from shifting during tire operation, affecting the heat dissipation of the outer tire body 1.
[0035] In one embodiment, the module 21 has interlocking splicing surfaces 211 at both ends; the splicing surface 211 can be any of the following: inclined surface, concave-convex surface, or plane. The module 21 can be spliced together from modules 21 of different sizes. The modules 21 are tightly spliced together by the interlocking splicing surfaces 211, ensuring the integrity and stability of the structure of the airless inner tube 2, and making it easy to assemble and disassemble.
[0036] In one embodiment, the wheel is provided with an air inlet and outlet hole that communicates with the vent 31; the area of the air inlet and outlet hole on the wheel can be larger than the ventilation area of the vent 31, effectively communicating with the ventilation system 3 on the module 21, providing an inlet and outlet channel for ventilation and heat dissipation of the outer tire body 1, and accelerating air flow.
[0037] In one embodiment, the outer tire body 1, the airless inner tube 2, and the annular support pad 5 are made of rubber or elastic material.
[0038] In use, this utility model is as follows: In Embodiment 1, firstly, select one module 21 and install it inside the outer tire body 1, ensuring the inner wall of the outer tire body 1 is flush with the outer circumferential surface of the module 21. Then, connect the remaining modules 21 sequentially along the splicing surface 211 to the already installed modules 21. After all modules 21 are installed, an airless inner tube 2 is formed. Finally, connect the outer tire body 1, now equipped with the airless inner tube 2, to the wheel. When the vehicle is in motion, the wheel rotates, and cold air from the outside enters through the air inlet / outlet on the wheel, flowing along the ventilation opening 31 on the module 21 into the air duct 32. The cold air contacts module 21 to cool it down. The tire body 1 transfers heat to module 21 through contact with it, thereby cooling the tire body 1. The cold air in the air duct 32 can also enter the double ventilation gap 4 and other inner walls of the tire body 1 through the second ventilation port 33 to directly cool the inner walls of the tire body 1. At the same time, the heat of the tire body 1 can also be squeezed by the vibration during driving and discharged through the first ventilation port 31 and the air inlet and outlet on the wheel to achieve continuous and efficient heat dissipation and ensure stable tire performance.
[0039] In Example 2, firstly, the annular support pad 5 is installed onto the inner wall of the outer tire body 1. The outer surface of the annular support pad 5 is attached to the inner wall of the outer tire body 1, thus opening up the inner wall of the outer tire body 1. Then, the module 21 with the positioning boss 22 is installed onto the annular support pad 5. During installation, the positioning boss 22 needs to be inserted into the positioning groove 51 on the annular support pad 5 to ensure that the ventilation port 3 52 on the annular support pad 5 is connected to the ventilation port 2 33 on the module 21. Then, the remaining modules 21 are spliced together sequentially through the splicing surface 211 of the module 21 to form the airless inner tube 2. Finally, the outer tire body 1 with the airless inner tube 2 installed is installed on the wheel, ensuring that the air inlet and outlet on the wheel are connected to the ventilation port 31 on the module 21. When the vehicle is driving, the vehicle... As the wheel rotates, cold air from the outside enters through the air inlets and outlets on the wheel, and enters the air duct 32 through the ventilation opening 31 on module 21. The cold air contacts module 21, cooling it down. The tire body 1 transfers heat to module 21 through contact with it, thus cooling the tire body 1. The cold air in the air duct 32 can also enter the double ventilation gap 4 through ventilation opening 33, and enter the other inner walls of the tire body 1 through ventilation opening 33 and ventilation opening 52, directly cooling the inner walls of the tire body 1. At the same time, the heat from the tire body 1 can also be compressed by the vibration during driving, and the hot air in the air duct 32 can be discharged through ventilation opening 31 and the air inlets and outlets on the wheel, achieving continuous and efficient heat dissipation and ensuring stable tire performance.
[0040] If a module 21 is damaged, the outer tire body 1 can be removed from the wheel and the damaged module 21 can be replaced. If the outer tire body 1 is damaged, the module 21 can be removed and installed into a new outer tire body 1 to quickly restore the tire to normal use.
[0041] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
