DETAILED DESCRIPTION
[0022] 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.
[0023] See also Figure 1-4 The utility model provides a technical solution: a puncture-proof rubber tire, including a rubber tire body 1, the rubber tire body 1 including a tread 11, a sidewall 12 and a tire lip 13, a first bulletproof fiber layer 14 is fixedly arranged on the inner side of the tread 11, a second bulletproof fiber layer 15 is fixedly arranged on the inner side of the first bulletproof fiber layer 14, a cord layer 16 is fixedly arranged on the inner side of the second bulletproof fiber layer 15, and an inner layer 17 is fixedly arranged on the inner side of the cord layer 16.
[0024] Among them, a first bulletproof fiber layer 14 and a second bulletproof fiber layer 15 are added between the tread 11 and the carcass layer 16. The first bulletproof fiber layer 14 and the second bulletproof fiber layer 15 are both made of bulletproof fiber materials. Two layers are added between the tread 11 and the carcass layer 16 to improve the structural strength of the tread 11 and the puncture resistance of the tread 11. When the rubber tire body 1 is running on the road, it will not be easily punctured by sharp objects and has good puncture resistance.
[0025] The first bulletproof fiber layer 14 and the second bulletproof fiber layer 15 replace the conventional multi-layer steel cord to improve the puncture resistance of the rubber tire body 1 .
[0026] Among them, the inner layer 17 is a polymer composite material, which is an existing technology. The material has great viscosity and elasticity. When a sharp object pierces the inside of the tire, the inner layer 17 will activate its self-repairing ability, completely wrap the sharp object inside, and use its own viscosity to bond the wound, thereby ensuring that the rubber tire body 1 can continue to run normally on the road and prevent the rubber tire body 1 from being broken, leaking, and bursting. The inner layer 17 is used in conjunction with the bulletproof fiber layer to enhance the anti-puncture performance of the rubber tire body 1 and improve driving safety.
[0027] A plurality of first steel wire bundles 113 are arranged inside the tread 11 , and the structural strength of the tread 11 is enhanced by the plurality of first steel wire bundles 113 .
[0028] A plurality of groups of second steel wire bundles 121 are arranged inside the sidewall 12 , and the structural strength of the sidewall 12 is enhanced by the plurality of groups of second steel wire bundles 121 .
[0029] Among them, multiple groups of third steel wire bundles 131 are arranged inside the tire lip 13, and the structural strength of the tire lip 13 is enhanced by the multiple groups of third steel wire bundles 131. The structural strength of the tread 11, the sidewall 12 and the tire lip 13 is enhanced by multiple groups of first steel wire bundles 113, second steel wire bundles 121 and third steel wire bundles 131, so that the tread 11, the sidewall 12 and the tire lip 13 can resist a certain external force of foreign objects piercing, thereby achieving the purpose of anti-puncture.
[0030] Among them, the first steel wire bundle 113, the second steel wire bundle 121 and the third steel wire bundle 131 are all set as ring-shaped structures. The first steel wire bundle 113, the second steel wire bundle 121 and the third steel wire bundle 131 are evenly stressed, ensuring the stability of the rubber tire body 1 during the driving of the car.
[0031] Among them, multiple groups of steel wire bundles improve the structural strength of the tire and protect the internal structure of the tire even in the event of a violent collision.
[0032] The first steel wire bundle 113, the second steel wire bundle 121 and the third steel wire bundle 131 are all composed of multiple groups of steel wire fibers, and the steel wire bundles are twisted from multiple groups of steel wire fibers.
[0033] Among them, multiple groups of first steel wire bundles 113 are evenly distributed along the contour direction of the tread 11 , multiple groups of second steel wire bundles 121 are evenly distributed along the contour direction of the sidewall 12 , and multiple groups of third steel wire bundles 131 are evenly distributed along the contour direction of the tire lip 13 .
[0034] A plurality of groups of pattern protrusions 111 are arranged on the outer side of the tread 11 .
[0035] Among them, multiple groups of pattern grooves 112 are formed between the multiple groups of pattern protrusions 111. The multiple groups of pattern protrusions 111 on the tread 11 are the parts of the rubber tire body 1 that are in closest contact with the ground. The multiple groups of pattern protrusions 111 and the multiple groups of pattern grooves 112 can increase driving force, friction force and braking force, and can also assist in drainage.
[0036] Working principle: A first bulletproof fiber layer 14 and a second bulletproof fiber layer 15 are added between the tread 11 and the cord layer 16. Both the first bulletproof fiber layer 14 and the second bulletproof fiber layer 15 are made of bulletproof fiber materials. Two layers are added between the tread 11 and the cord layer 16 to improve the structural strength of the tread 11 and the puncture resistance of the tread 11. The inner layer 17 is a polymer composite material with great viscosity and elasticity. When a sharp object pierces the inside of the tire, the inner layer 17 will activate its self-repairing ability, completely wrap the sharp object inside, and The wound is bonded with its own viscosity to ensure that the rubber tire body 1 can continue to run normally on the road, and the rubber tire body 1 is prevented from being punctured, leaked, or blown out. The inner layer 17 is used in conjunction with the bulletproof fiber layer to enhance the puncture resistance of the rubber tire body 1 and improve driving safety. Multiple groups of first steel wire bundles 113, second steel wire bundles 121, and third steel wire bundles 131 enhance the structural strength of the tread 11, sidewalls 12, and tire lips 13, so that the tread 11, sidewalls 12, and tire lips 13 can resist a certain amount of external force from foreign objects piercing into them, thereby achieving the purpose of puncture resistance.
