Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tire, in particular to a kind of engineering tire based on nylon reinforcing structure. BACKGROUND

[0002] Engineering tire, also known as engineering machinery tire, is a tire composed of cord layer, bead, buffer layer, tread and other parts. Compared with ordinary tires, the carcass structure of engineering tires is more solid, has strong load-carrying capacity, and can adapt to various complex and harsh working conditions, such as mines and construction sites, to provide stable support for engineering operations.

[0003] With regard to the above-mentioned related technology, the inventors have found that in actual application, especially in complex terrains such as mines and construction sites, engineering tires face severe challenges. Sharp objects in these environments, such as stones and steel bars, can easily cause impact on the tire sidewall, leading to damage to the cord, bulging of the sidewall, and even serious consequences such as tire blowout. In addition, as the use time extends, the carcass cord and sidewall may gradually develop cracks due to shear deformation accumulation under the action of heavy load and complex stress, further affecting the durability and safety of the tire. Therefore, there is an urgent need to develop an engineering tire based on a nylon reinforcing structure. SUMMARY

[0004] The technical problem solved by the utility model is to provide an engineering tire based on a nylon reinforcing structure, which can reduce the risk of sidewall cracking, improve the overall structural strength of the tire, and reduce the probability of cord breakage, sidewall bulging, and even tire blowout.

[0005] To solve the above technical problems, one technical solution adopted by the utility model is to provide an engineering tire based on a nylon reinforcing structure, which includes: a tread rubber and a non-slip boss arranged on the surface thereof. The tread rubber is sequentially provided with a buffer layer assembly, a reinforcing layer assembly, and a carcass from the outside to the inside. The inner edge of the carcass is respectively covered and connected with a bead wire. The outer side of the inner edge of the carcass is respectively covered with a thickened layer. The engineering tire further includes an inner liner rubber core connected with the bead wire.

[0006] The reinforcing layer assembly includes a belt layer one and a belt layer two sequentially arranged from the outside to the inside. The two sides of the belt layer two are respectively connected with a shoulder pad rubber one. The opposite top sides of the shoulder pad rubber one are respectively provided with accommodating areas. The two ends of the belt layer two are respectively located in the accommodating areas. The two ends of the belt layer one are respectively arranged in opposite directions.

[0007] The opposite two sides of the shoulder pad rubber one are respectively connected with a sidewall nylon composite layer. One end of the sidewall nylon composite layer is connected with the carcass.

[0008] By adopting the above technical scheme, the tread rubber and the anti-skid boss are in direct contact with the ground, are used to provide sufficient friction and grip to improve the driving stability and safety of the tire, cooperate with the buffer layer assembly to reduce the impact and vibration of the tire during driving, in addition, the reinforcing layer assembly is used to enhance the strength and stability of the tire, so that the tire is more stable during heavy load or high speed driving, reduces the deformation and wear of the tire, the shoulder pad rubber is used to protect and support the belt layer two, and the accommodating area is used to accommodate the two ends of the belt layer two, ensures the correct installation and positioning of the belt layer, the tire side nylon composite layer is used to enhance the impact resistance and wear resistance of the tire side, reduces the damage of the tire side caused by sharp objects, the thickening layer is used to increase the rigidity and carrying capacity of the tire, the steel wire ring and the inner liner rubber core provide a solid support structure for the tire and protect the inside of the tire from moisture and impurities.

[0009] In a preferred example, the buffer layer assembly further comprises a buffer layer and a nylon steel wire interlaced layer arranged from outside to inside, the two sides of the buffer layer are connected with shoulder pad rubber two respectively, and the two sides of the nylon steel wire interlaced layer are connected with zero-degree belt layer respectively.

[0010] By adopting the above technical scheme, the buffer layer absorbs the road bumping energy, reduces the tire body fatigue, especially protects the tire body cord in complex terrain such as gravel and mud, the nylon steel wire interlaced layer provides additional support and stability for the tire, effectively resists the deformation of the tire during driving, cooperates with the shoulder pad rubber two to fill the gap between the tire shoulder and the tread, enhances the support of the tire shoulder, provides additional damping effect, and the zero-degree belt layer can effectively constrain the circumferential deformation of the tire, improve the rigidity and stability of the tire, and disperse the stress of the tread, prolong the service life of the tire.

[0011] In a preferred example, the tire side nylon composite layer comprises warp nylon cords and weft nylon cords, and the warp nylon cords and the weft nylon cords are vertically interlaced and connected.

[0012] By adopting the above technical scheme, the warp nylon cords and the weft nylon cords are vertically interlaced and connected to form a network structure, effectively resist stress and deformation from all directions, thereby enhancing the structural strength of the tire side, dispersing impact energy, reducing local stress concentration, and enhancing the impact resistance of the tire.

[0013] In a preferred example, the nylon steel wire interlaced layer comprises a nylon wire group and a steel wire group, and the nylon wire group and the steel wire group are respectively interlaced at an included angle.

[0014] By adopting the technical scheme, the nylon wire group and the steel wire group are connected in an angle interweaving mode to form a composite reinforcing structure, which combines the high strength of nylon and the high rigidity of steel wire, and enhances the load bearing capacity and structural strength of the tire, and the angle interweaving of the nylon wire group and the steel wire group can more effectively disperse the stress inside the tire, which helps to reduce local stress concentration and reduce the risk of damage of the tire due to excessive stress.

[0015] In a preferred example, the width of the belt layer one is greater than the width of the belt layer two.

[0016] By adopting the technical scheme, the width of the belt layer one is greater than the width of the belt layer two, which can further disperse the stress received by the tire during driving, reduce local stress concentration, support the shoulder of the tire, and enhance the stability of the tire in the shoulder area.

[0017] In a preferred example, the nylon wire group is woven by not less than three nylon wires, and the steel wire group is woven by not less than three steel wires.

[0018] By adopting the technical scheme, the nylon wire group is woven by multiple nylon wires, which increases the thickness and density of the material, thereby improving the wear resistance of the tire, and at the same time, the nylon material itself has good cutting resistance, which helps to reduce damage caused by sharp objects piercing the tire.

[0019] In summary, the utility model has at least one of the following beneficial technical effects of the engineering tire based on the nylon reinforcing structure:

[0020] 1. The shock and vibration received by the tire during driving are reduced by the buffer layer assembly, and the strength and stability of the tire are enhanced by the reinforcing layer assembly, so that the tire is more stable during heavy load or high speed driving, the deformation and wear of the tire are reduced, and the driving stability and safety of the tire are improved under the action of the tread rubber and the anti-skid boss.

[0021] 2. The multi-directional stress dispersion network is formed by the nylon steel wire interlaced layer and the tire side nylon composite layer, which can absorb road impact energy and inhibit crack propagation, and the nylon fiber and the steel wire are interwoven to form a high-strength composite structure, which can resist the impact of sharp objects and reduce the risk of tire side bulging and cord rupture, in addition, the difference in elastic modulus of nylon and steel wire forms a gradient stress transmission path, reduces the interlayer shear stress, and further reduces the risk of tire side crack.

[0032] The preferred embodiments of the present application will be described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0033] It should be noted that these drawings are simplified schematic views, and only illustrate the basic structure of the present application in a schematic manner, and therefore only show the relevant components of the present application.

[0034] Reference Figures 1-4The utility model discloses a kind of engineering tires based on nylon reinforcing structure, comprising: tread rubber 1 and the anti-skid boss 2 on its surface, tread rubber 1 is sequentially provided with buffer layer assembly 30, reinforcing layer assembly 40 and carcass 5 from outside to inside, the inner edge of carcass 5 is covered with steel wire ring 6 respectively, the outside of carcass 5 inner edge is covered with thickening layer 7, further comprising inner liner rubber core 8 connected with steel wire ring 6, reinforcing layer assembly 40 includes belt layer one 41 and belt layer two 42 sequentially provided from outside to inside, the width of belt layer one 41 is greater than the width of belt layer two 42, the two sides of belt layer two 42 are connected with shoulder pad rubber one 43 respectively, shoulder pad rubber one 43 opposite top side is respectively equipped with accommodating area 44, the two ends of belt layer two 42 are located in accommodating area 44 respectively, the two ends of belt layer one 41 are respectively extended and set to opposite direction, the opposite two sides of shoulder pad rubber one 43 are respectively connected with side nylon composite layer 45, one end of side nylon composite layer 45 is connected with carcass 5, and side nylon composite layer 45 includes warp nylon cord 451 and weft nylon cord 452, and warp nylon cord 451 and weft nylon cord 452 are connected vertically interlaced;

[0035] Warp nylon cord 451 and weft nylon cord 452 are interlaced to form high-strength composite structure, which can resist impact of sharp objects, reduce the risk of sidewall bulging and cord rupture, and the difference in elastic modulus of nylon and steel wire can form a gradient stress transmission path, reduce interlayer shear stress and inhibit delamination. In addition, warp nylon cord 451 is arranged along the axial direction of the tire to bear circumferential stress and inhibit the circumferential deformation of the sidewall to prevent bulging or collapse caused by uneven load. Weft nylon cord 452 is arranged perpendicular to warp nylon cord 451 to bear radial stress to disperse sharp object impact energy and reduce local stress concentration. The vertical interlaced structure of the two forms a "grid" to uniformly decompose impact force in any direction into warp and weft components, reducing the risk of fatigue rupture of a single cord. The vertical interlacing of warp nylon cord 451 and weft nylon cord 452 also blocks the crack propagation path, delaying fatigue failure. Moreover, since the width of belt layer one 41 is greater than the width of belt layer two 42, it can be known that the wider belt layer one 41 bears the main circumferential stress, such as carcass 5 tension, while the narrower belt layer two 42 disperses radial stress, such as road impact, through angle design. This width difference forms a gradient stress path, which can reduce the stress concentration risk of a single material and enhance the rigidity of the tire crown, reducing the risk of delamination caused by shear deformation at the tire shoulder.

[0036] The buffer layer assembly 30 comprises a buffer layer 31 and a nylon steel wire interlaced layer 32 arranged from outside to inside in sequence, two sides of the buffer layer 31 are connected with shoulder pad rubbers two 33 respectively, two sides of the nylon steel wire interlaced layer 32 are connected with zero-degree belt layers 34 respectively, opposite ends of the shoulder pad rubbers two 33 are connected with side nylon composite layers 45 respectively, the nylon steel wire interlaced layer 32 comprises a nylon wire group 321 and a steel wire group 322, the nylon wire group 321 and the steel wire group 322 are interlacedly connected at an included angle respectively, the nylon wire group 321 is woven by not less than three nylon wires, and the steel wire group 322 is woven by not less than three steel wires;

[0037] The nylon wire is treated by dipping glue, so that the adhesion with the rubber matrix is enhanced, and the strength reduction caused by hygroscopicity is inhibited, and meanwhile, the steel wire group 322 is spirally woven by not less than three steel wires, so that the circumferential stress of the tire crown can be further borne, and the deformation of the tread is inhibited.

[0038] The implementation principle of the embodiment is as follows: in use, the anti-skid boss 2 is directly contacted with the ground to provide sufficient friction and grip to improve the driving stability and safety of the tire, and the buffer layer assembly 30 is cooperated to reduce the impact and vibration of the tire in the driving process, and since the longitudinal nylon cord 451 and the weft nylon cord 452 are perpendicularly interlaced to form a grid support system, the circumferential stress and the radial stress are decomposed into multi-directional components to inhibit the deformation and crack propagation of the tire side, in this process, the buffer layer assembly 30 reduces the impact and vibration of the tire in the driving process, and cooperates with the belt layer two 42 and the belt layer one 41 to optimize the ground pressure distribution, so as to enhance the impact resistance and wear resistance of the tire side, reduce the damage of the tire side caused by sharp objects, and cooperate with the thickening layer 7 to increase the rigidity and carrying capacity of the tire.

[0039] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation according to the content of the utility model specification, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
