[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims. They can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the vehicle's driving performance.

[0003] After searching, the existing patent (publication number: CN220447586U) discloses a wear-resistant rubber tire, including: a wheel hub, an air bag, a movable sleeve arranged on the outer surface of the wheel hub, a through hole, which is opened inside the wheel hub, an air outlet, which is fixedly sleeved inside the air bag, one end of the air outlet is movably sleeved inside the through hole, an air outlet plate, which is fixedly mounted on one end of the air outlet, an air outlet hole is opened on the outer surface of the air outlet plate, an elastic member, which is fixedly mounted on one side of the air outlet plate, and a mounting plate is fixedly mounted on the other end of the elastic member. When the utility model is in use, when the tire collides with a protruding object on the ground while driving on the road, when the force of the gas pressure inside the air bag is greater than the force of the elastic member, the gas pushes open the sealing rod and brings the sealing pad, so as to open the position of the air outlet on the air outlet plate, which is conducive to the escape of gas, completes energy release, reduces the effect of pressure on the air bag and the tread, reduces the damage to the wheel hub, the air bag and the tread, and prolongs the service life.

[0004] When the above patented technology is in use, when the tire collides with a protruding object on the ground, the force of the gas pressure inside the airbag is greater than the force of the elastic member, causing the gas to escape from the air outlet. After the gas in the airbag escapes from the air outlet, the air pressure in the airbag decreases. After multiple times, the gas in the airbag is in an insufficient state, and the airbag is in a deflated state to a certain extent, which may affect normal driving. Therefore, a wear-resistant rubber tire is proposed. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-Figure 5 The utility model provides a technical solution: a wear-resistant rubber tire, including a tread 1, a wheel hub 2 and an airbag 3. The interior of the airbag 3 is fixedly connected with an exhaust pipe 4, which passes through the outer surface of the wheel hub 2. The other end of the exhaust pipe 4 is fixedly connected with a balancing box 5. The inner surface of the exhaust pipe 4 is fixedly connected with a first fixed disk 9. The outer surface of the first fixed disk 9 is movably inserted with a first sealing rod. The first sealing rod is fixedly connected with a first blocking block 8 at one end close to the interior of the balancing box 5. The first blocking block 8 is fitted with the interior of the exhaust pipe 4. A first spring 7 is fixedly connected between the opposite outer surfaces of the first fixed disk 9 and the first blocking block 8. The first spring 7 is sleeved on the outer surface of the first sealing rod. The outer surface of the balancing box 5 is fixedly connected with a circulation cylinder 6. The circulation cylinder 6 passes through the outer surface of the wheel hub 2. The other end of the circulation cylinder 6 is fixedly connected with the interior of the airbag 3. The inner surface of the circulation cylinder 6 is fixedly connected with a second fixed disk 12. The outer surface of the second fixed disk 12 is movably inserted with a second sealing rod. A second block 11 is fixedly connected to one end near the interior of the airbag 3, and the second block 11 fits with the interior of the circulation tube 6. A second spring 10 is fixedly connected between the second fixed plate 12 and the second block 11, and the second spring 10 is sleeved on the outer surface of the second sealing rod. In this embodiment, when the tire is driving on the road, the crown 1 and the airbag 3 are deformed by foreign objects on the road, and the pressure in the airbag 3 increases. When the pressure in the airbag 3 is greater than the elastic force of the first spring 7, the pressure overcomes the elastic force of the first spring 7, so that the first block 8 is detached from the interior of the exhaust tube 4, and the air pressure enters the interior of the balance box 5, thereby protecting the airbag 3 and the crown 1 and reducing damage to them. Then, when the air pressure in the balance box 5 increases, the air pressure overcomes the elastic force of the second spring 10, so that the second block 11 is detached from the interior of the circulation tube 6, so that the air pressure re-enters the interior of the airbag 3, so that the air pressure inside the airbag 3 is in a relatively balanced state, which is not easy to affect normal driving.

[0025] The outer surface of the end of the balance box 5 opposite to the exhaust pipe 4 is fixedly connected to the air outlet pipe 14, and the interior of the air outlet pipe 14 is fixedly connected to a third fixed disk, and a third sealing rod is movably inserted into the outer surface of the third fixed disk, and the outer surface of the third sealing rod away from the interior of the balance box 5 is fixedly connected to a third blocking block 16, and the third blocking block 16 fits with the interior of the air outlet pipe 14, and a third spring 15 is fixedly connected between the third fixed disk and the third blocking block 16. In this embodiment, when the pressure is too high, the air pressure enters the balance box 5, and the excessive air pressure in the balance box 5 overcomes the elastic force of the third spring 15, so that the third blocking block 16 is detached from the interior of the air outlet pipe 14. At this time, the air pressure is discharged to the outside air to perform pressure relief work, thereby further protecting the airbag 3 and the tire crown 1.

[0026] A push rod 18 is movably inserted into the left outer surface of the balance box 5, and a limiting cylinder 19 is fixedly connected to the outer surface of the first blocking block 8. A limiting hole 20 is provided on the outer surface of the limiting cylinder 19. In the present embodiment, when it is necessary to inflate the interior of the airbag 3, the push rod 18 is pushed so that one end of the push rod 18 is inserted into the interior of the limiting hole 20 to limit the limiting cylinder 19, thereby preventing most of the pressure from entering the balance box 5 during inflation.

[0027] The left inner surface of the balance box 5 is fixedly connected with the piston cylinder 17, and the outer surface of the push rod 18 is fixedly sleeved with a piston disk 21. The piston disk 21 is movably fitted with the inside of the piston cylinder 17. In this embodiment, the piston disk 21 increases the sealing between the piston cylinder 17, thereby avoiding the leakage of air pressure from the contact point between the push rod 18 and the balance box 5.

[0028] The outer surface of the airbag 3 is fixedly connected with an air nozzle 13 , which penetrates the outer surface of the wheel hub 2 . In this embodiment, the airbag 3 is inflated through the air nozzle 13 .

[0029] The first blocking block 8, the second blocking block 11 and the third blocking block 16 are all in the shape of a truncated cone, and the end of the first blocking block 8 facing the outside of the exhaust pipe 4, the end of the second blocking block 11 facing the outside of the circulation pipe 6 and the end of the third blocking block 16 facing the outside of the outlet pipe 14 are the thicker ends of the truncated cone. In the present embodiment, through the above-mentioned technical scheme, when the first blocking block 8, the second blocking block 11 and the third blocking block 16 block the exhaust pipe 4, the circulation pipe 6 and the outlet pipe 14 respectively, the sealing is better.

[0030] The elastic coefficient of the third spring 15 is greater than the elastic coefficient of the second spring 10 . In this embodiment, the third spring 15 is prevented from being compressed under the action of pressure within a certain pressure range, thereby causing air pressure to be discharged from the air outlet 14 .

[0031] The outer surface of the tread crown 1 is provided with a plurality of wear-resistant grooves. In this embodiment, the wear-resistant grooves enable the outer ring of the tread crown 1 to resist the friction with the ground, which is beneficial to improving the wear resistance of the tire.

[0032] Working principle: When the utility model is in use, when the tire is traveling on the road, the crown 1 and the airbag 3 are deformed by foreign objects on the road, and the pressure in the airbag 3 increases. When the pressure in the airbag 3 is greater than the elastic force of the first spring 7, the pressure overcomes the elastic force of the first spring 7, so that the first block 8 is detached from the exhaust pipe 4, and the air pressure enters the balance box 5, thereby protecting the airbag 3 and the crown 1 and reducing the damage caused to them. Then, when the air pressure in the balance box 5 increases, the air pressure overcomes the elastic force of the second spring 10, so that the second block 11 is detached from the circulation tube 6, and the air pressure re-enters the airbag 3, so that the air pressure inside the airbag 3 is in a relatively balanced state, which is not easy to affect normal driving.

[0033] When the pressure is too high, the air pressure enters the balance box 5. The excessive air pressure in the balance box 5 overcomes the elastic force of the third spring 15, so that the third block 16 is separated from the inside of the air outlet 14. At this time, the air pressure is discharged to the outside air to relieve the pressure, and the airbag 3 and the crown 1 are further protected. When it is necessary to inflate the inside of the airbag 3, the push rod 18 is pushed so that one end of the push rod 18 is inserted into the inside of the limiting hole 20 to limit the limiting tube 19 to avoid most of the pressure entering the balance box 5 during inflation. After inflation, the push rod 18 can be pulled out.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
