Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a tire with a multiple sealing structure. Background Art

[0002] The existing Chinese patent document CN216636022U discloses a PU tire with a shock-absorbing structure. It points out that although the wheel structure of a general PU tire can ensure stable support, when the PU tire rolls on an uneven surface, it is fixed to the connected rotating shaft structure, so that the vibration caused by the collision of the PU tire will be directly transmitted to the various structures connected to the rotating shaft, which not only reduces the user's comfort, but also causes the various structures connected to the PU tire to be damaged due to the vibration, increasing the risk of use. The solution is to connect the driven rotating shaft with the shock-absorbing mechanism, so that when the tire rolls on the ground, the shock-absorbing mechanism is used to offset the rotating shaft and the tire, which can avoid vibration caused by the tire colliding with the ground. At the same time, the buffer mechanism is used to buffer and reset the offset shock-absorbing mechanism, thereby improving the shock resistance of the tire.

[0003] When the above scheme and the existing technology are used for tires, most of the existing tires have only one layer of sealing structure. When the tire contacts a sharp obstacle during driving, it will deflate, causing the air pressure inside the tire to be too low. There is a risk of tire derailment or blowout when the vehicle is turning or driving at high speed. In serious cases, it will endanger the safety of the driver and passengers, and cannot meet actual use needs. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 , this utility model provides three technical solutions:

[0022] Example 1: A tire with a multiple sealing structure, including a tire main body sealing auxiliary assembly;

[0023] The tire body includes an outer tire 1 and an inner tire 2, and the inner tire 2 is provided on the inner side of the outer tire 1, and the inner tire 2 is provided with a sealing auxiliary component;

[0024] The outer tire 1 is made of wear-resistant rubber with high strength and elasticity, which directly contacts the ground and protects the inner tire from damage;

[0025] The inner tube 2 is a ring-shaped rubber tube equipped with a valve to allow air to be inflated or exhausted. The inner tube is filled with compressed air at a certain pressure. Generally, tires with an air pressure of 0.5-0.7 MPa are called high-pressure tires, those with an air pressure of 0.15-0.45 MPa are called low-pressure tires, and those with an air pressure below 0.15 MPa are called ultra-low-pressure tires. Almost all cars and trucks use low-pressure tires because they have good elasticity, a wide cross-section, a large contact surface with the road, and a thin wall that allows for good heat dissipation. This improves the vehicle's ride smoothness and steering stability.

[0026] The outer surface of the tire 1 is provided with a tread crown 13 , and the tread crown 13 is provided with tread grooves 14 , and there are two groups of tread grooves 14 . The side of the tire 1 is provided with a sidewall 15 , and a shoulder 16 is provided at the connection between the sidewall 15 and the tread crown 13 .

[0027] The crown 13, also known as the running surface, is in direct contact with the road surface, bearing impact and wear, and protecting the tire body from mechanical damage. To increase adhesion between the tire and the road surface and prevent longitudinal and lateral slippage, various patterns are formed on the crown 3.

[0028] The shoulder 16 is the transition between the thicker crown and the thinner sidewall, and has various patterns to prevent slipping and dissipate heat;

[0029] The sidewall 15 is a thin rubber layer attached to the sidewall of the tire 1. Its function is to protect the cord layer of the sidewall 15 from mechanical damage and water erosion. The sidewall 15 does not contact the ground and generally does not wear, but it is subject to large flexural deformation.

[0030] Example 2: Based on Example 1, the sealing auxiliary component includes a sealing layer 8; the sealing layer 8 is arranged on the inner wall of the inner tube 2, and the inner wall of the sealing layer 8 is fixedly provided with sealing strips 9 at equal intervals, and the sealing strips 9 on the inner side of the sealing layer 8 are adapted and connected to the sealing groove 7 provided on the outer wall of the cushioning strip 3 to ensure its sealing performance, and the inner wall of the sealing layer 8 is connected with the cushioning strip 3.

[0031] The cushioning strip 3 is an annular rubber strip that is placed between the inner tube 2 and the rim to protect the inner tube 2 from being worn by the rim and the tire bead, and to prevent dust and water vapor from penetrating into the tire.

[0032] The inner wall of the pad belt 3 is fixedly provided with a sealing ring groove 6, and the sealing ring groove 6 inside the pad belt 3 is adapted to be connected with the sealing ring 5 provided on the outer wall of the wheel hub 4, and the inner wall of the pad belt 3 is connected with the wheel hub 4.

[0033] Embodiment 3: Based on embodiment 2, a buffer layer 10 is connected to the outer wall of the inner tube 2 .

[0034] A protective layer 11 is connected to the outer wall of the buffer layer 10 .

[0035] The protective layer 11 is adapted and connected to the connecting groove 12 on the inner side of the tire 1 .

[0036] During use, be sure to properly inflate your tires and ensure the tire pressure is within the specified value. Tire pressure that is too high or too low will increase wear and reduce mileage. When tire pressure is below the specified value, shoulder wear increases dramatically. When tire pressure is above the specified value, the tire's contact patch decreases, resulting in increased unit pressure and increased wear in the center of the tread. This also increases tire rigidity, increasing the dynamic load on the wheel and making it more likely to cause a carcass rupture. This impact is even more severe on uneven roads or when driving at high speeds.

[0037] Before driving, inspect your tires for bulges, cracks, cuts, nail punctures, deflation, and abnormal wear. Repair any findings immediately. Check the tire tread for debris, metal fragments, glass, or other punctures. Remove any foreign objects, such as stones, from the grooves. Remove any such objects with a screwdriver. Check the tightness of the tire nuts and tighten them if loose. If the tire pressure is 20% below standard, remove the tire immediately at a nearby tire shop and have it inspected by a professional. Check the wheel rims for deformation, cracks, or other damage to ensure safe driving.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
