Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a novel all-steel radial tire. Background Art

[0002] With the continuous development of society, ordinary tires can no longer meet people's normal needs. Among them, all-steel radial tires are widely recognized and used. All-steel radial tires are also called all-steel load-bearing radial tires. The carcass cords are arranged in the meridian direction, and there are belt layers with cords arranged almost in the circumferential direction to tighten the carcass. This type of tire is called a radial tire.

[0003] The current all-steel radial tire is mainly composed of an inner hard triangle rubber core, an outer soft triangle rubber core, a carcass cord, a bead reinforcing steel cord, a bead rubber, a sidewall rubber, a nylon cord surface and an inner liner. Although the all-steel radial tire of this structure can achieve normal movement of the equipment when in use, on the one hand, due to the relatively weak side of the all-steel radial tire of this structure, the side of the all-steel radial tire is very easy to be scratched and damaged when in use. On the other hand, due to the certain flame retardant and noise reduction performance of the all-steel radial tire itself, it is easy to spontaneously combust and be damaged during long-term high-speed driving, and it is also easy to generate loud noise, which makes the safety and comfort of the all-steel radial tire poor when in use. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide a new all-steel radial tire which can effectively increase the structural strength of the tire side and has good shock absorption, sound absorption and flame retardant properties in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is achieved through the following technical scheme: the utility model proposes a novel all-steel radial tire, including a carcass, a tread is installed on the outer side of the carcass, a belt layer is installed on the inner side of the tread, a protective layer is installed on the inner side of the belt layer, the protective layer includes a shock-absorbing and sound-absorbing layer and a flame-retardant layer installed inside the shock-absorbing and sound-absorbing layer, a carbon fiber reinforcement layer is installed on the outer side of the carcass, and a steel mesh reinforcement layer is installed on the carcass corresponding to the inner side of the carbon fiber reinforcement layer.

[0008] Furthermore, a carcass ply is installed inside the carcass and located inside the steel wire mesh reinforcement layer, and an airtight layer is bonded to the inner wall of the carcass ply.

[0009] By adopting the above technical solution, the carcass cord layer can effectively increase the structural strength of the carcass, and the airtight layer can significantly increase the airtightness inside the carcass.

[0010] Furthermore, the carcass cord layer includes a steel ring at its edge, and a V-belt is installed on the upper side of the steel ring in the carcass cord layer.

[0011] By adopting the above technical solution, the V-belt can ensure the reliable installation of the steel ring in the carcass cord layer, and the tire can be reliably installed on the equipment wheel hub with the help of the steel ring.

[0012] Furthermore, the tread is made of a rubber belt and has anti-skid grooves.

[0013] By adopting the above technical solution, the wear resistance of the tire can be effectively ensured.

[0014] Furthermore, the carbon fiber reinforcement layer is bonded to the side of the carcass, and the carbon fiber reinforcement layer is an annular structure.

[0015] By adopting the above technical solution, the carbon fiber reinforcement layer is woven from carbon fiber mesh cloth, has good wear resistance and fracture resistance, and can effectively prevent the tire from being broken and damaged when it is scratched on the side.

[0016] Furthermore, the steel wire mesh reinforcement layer is bonded to the carcass cord layer, and the steel wire mesh reinforcement layer is an annular structure.

[0017] By adopting the above technical solution, the wire mesh reinforcement layer can further improve the fracture resistance of the tire side.

[0018] Furthermore, the shock-absorbing and sound-absorbing layer is made of special polyurethane sponge, and the flame-retardant layer is a nylon belt layer with flame retardant particles.

[0019] By adopting the above technical solution, the special polyurethane sponge as a tire interlayer can produce a powerful damping and shock absorption effect, blocking the sound waves generated when the tire rolls, and can also play a flame retardant and fireproof role under special circumstances. Combined with the design of the flame retardant layer, the tire has better flame retardant performance when in use.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the current all-steel radial tire is mainly composed of an inner hard triangle rubber core, an outer soft triangle rubber core, a carcass cord, a bead reinforced steel cord, a bead rubber, a sidewall rubber, a nylon cord surface and an inner liner, although the all-steel radial tire of this structure can realize the normal movement of the equipment when in use, on the one hand, due to the relatively weak side of the all-steel radial tire of this structure, the side of the all-steel radial tire is very easy to be scratched and damaged when in use, on the other hand, due to the certain flame retardant and noise reduction performance of the all-steel radial tire itself, it is easy to spontaneously combust and be damaged during long-term high-speed driving, and it is also easy to generate loud noise, making the safety and comfort of the all-steel radial tire in use limited. The utility model solves the problem of poor wear resistance and fracture resistance of the all-steel radial tire by installing a carbon fiber reinforcement layer and a steel mesh reinforcement layer on the side of the tire, thereby significantly increasing the wear resistance and fracture resistance of the side of the all-steel radial tire, effectively avoiding the drawback of the all-steel radial tire being scratched by the collision of external debris when running at high speed, and at the same time, with the design of the protective layer composed of the flame retardant layer and the shock-absorbing and sound-absorbing layer, the flame retardant and shock-absorbing and sound-absorbing properties of the all-steel radial tire are significantly improved, which not only avoids the natural safety hazards of the all-steel radial tire when running at high speed for a long time, but also makes the noise generated by the all-steel radial tire during use smaller, so that the comfort of the all-steel radial tire during use is improved.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figure 1-Figure 2As shown, a new all-steel radial tire in this embodiment includes a carcass 10, a tread 1 is installed on the outer side of the carcass 10, a belt layer 3 is installed on the inner side of the tread 1, and a protective layer 9 is installed on the inner side of the belt layer 3. The protective layer 9 includes a shock-absorbing and sound-absorbing layer 902 and a flame-retardant layer 901 installed inside the shock-absorbing and sound-absorbing layer 902. The shock-absorbing and sound-absorbing layer 902 is made of special polyurethane sponge, and the flame-retardant layer 901 is a nylon belt layer with flame retardant particles. The special polyurethane sponge can produce a strong damping and shock-absorbing effect as a tire interlayer to block the vibration generated when the tire rolls. The sound waves generated can also play a role in flame retardancy and fire prevention under special circumstances. Combined with the design of the flame retardant layer 901, the tire has better flame retardant performance when in use. A carbon fiber reinforcement layer 2 is installed on the outer side of the carcass 10, and a steel mesh reinforcement layer 4 is installed on the carcass 10 on the inner side of the carbon fiber reinforcement layer 2. The carbon fiber reinforcement layer 2 is woven from carbon fiber mesh cloth, and has good wear resistance and fracture resistance, which can effectively prevent the tire from being broken and damaged when it is scratched on the side. The steel mesh reinforcement layer 4 can further improve the fracture resistance of the tire side.

[0029] like Figure 1-Figure 2 As shown, in this embodiment, a carcass ply 5 is installed inside the carcass 10 on the inner side of the wire mesh reinforcement layer 4, and an airtight layer 7 is bonded to the inner wall of the carcass ply 5. The carcass ply 5 can effectively increase the structural strength of the carcass 10, and the airtight layer 7 can significantly increase the airtightness inside the carcass 10. The carcass ply 5 includes a steel ring 6 at the edge, and a V-belt 8 is installed on the upper side of the steel ring 6 in the carcass ply 5. The V-belt 8 can ensure the reliable installation of the steel ring 6 in the carcass ply 5, and the steel ring 6 can be used to achieve reliable installation of the tire on the equipment wheel hub.

The wire mesh reinforcement layer 4 is bonded to the carcass cord layer 5, and the wire mesh reinforcement layer 4 is an annular structure.

[0031] The specific implementation process of this embodiment is as follows: when in use, the all-steel radial tire only needs to be installed on the pre-installed wheel hub, and then the all-steel radial tire can be put into use. During use, by installing a carbon fiber reinforcement layer 2 and a steel mesh reinforcement layer 4 on the side of the tire, the wear resistance and fracture resistance of the side of the all-steel radial tire are significantly increased, effectively avoiding the disadvantage of the all-steel radial tire being scratched by the collision of external debris when driving at high speed. At the same time, with the design of the protective layer 9 composed of the flame retardant layer 901 and the shock-absorbing and sound-absorbing layer 902, the flame retardant and shock-absorbing and sound-absorbing properties of the all-steel radial tire are significantly improved, which not only avoids the natural safety hazards of the all-steel radial tire when driving at high speed for a long time, but also makes the noise generated by the all-steel radial tire during use smaller, so that the comfort of the all-steel radial tire during use is improved.
