Description
In daily life, automobiles are always the topics which can not be bypassed by people, and automobiles and various transportation tools can not be left in national defense construction and military construction. The automobile safety accidents are mostly caused by accidents of tires, so that the purpose of researching the safety of the automobile tires is to ensure that people go out and the use of wheel type carriers is safer, and the modernized construction of national defense construction army equipment is stronger.
One, the technical field
Various wheeled vehicles, wheeled equipment.
Second, background Art
The honeycomb-shaped high-pressure run-flat tire replaces the prior air bag type low and high-pressure pneumatic tire (detailed below).
Third, the invention
The honeycomb-shaped high-pressure run-flat tire is different from the current tire in that: the existing vacuum tyre is closed by combining an air bag with a wheel hub, the old tyre is closed by an inner air bag, and the air closing process of the high-pressure explosion-proof tyre is completed by a tyre body structure. The method comprises the following steps: the inner structure of the tire is made into a honeycomb shape, each honeycomb is an independent small space, and then the tire core is made by wrapping a high-strength steel wire mesh and a nylon mesh. The tyre core is put into an injection mould, simultaneously, the tyre surface layer and the honeycomb are injected with air or inert gas, the air pressure is 0.4-1mpa, and then the gas is sealed in the honeycomb holes through the tyre surface layer and the closed-gas honeycomb body. The tire does not need to be inflated again in the using process.
Fourthly, the honeycomb-shaped high-pressure explosion-proof tire is used for the automobile
1. Safety: the structure is strong, strong impact force transmitted from a road surface can be resisted, tire explosion in the driving process of an automobile can be avoided, if the tire of the automobile is damaged and leaked in an open mode in the driving process, driving cannot be affected, and the reason is that each honeycomb is of an independent structure, and the influence of the leakage of individual honeycomb on the tire is small, so that the honeycomb is safest.
2. Comfort: because of honeycomb shape high pressure run-flat tire can keep the gasbag elastic function of original tire, simultaneously because of honeycomb shape structure and material are high elastic material, its shock-absorbing capacity is good, and independent enclosed construction can resist the huge impact force that the road surface transmitted, and the tire grabs ground (soil) power more powerful, does not have on unevenness's road surface travel and has "peng, peng" this kind of strong short frequency sense of shaking, seems more steady.
3. The flat rate of tire can be accomplished littleer, is convenient for drive accuse: the honeycomb-shaped high-pressure run-flat tire has stronger resistance when turning, so the flat rate of the tire is made smaller, for example, the flat rate of a car tire can easily reach 245/40R18 or 245/35R19 (of course, the car tire needs a large flat rate, and the flat rate is selected after being repeatedly tested when being delivered from a factory), and the tire is not only suitable for urban and rural roads, but also more suitable for cross country and racing cars.
4. Energy conservation and environmental protection: compared with the existing vacuum tire, the service life of the tire can be prolonged by 20-30% on the premise of ensuring safe driving, the automobile tire used by people at present can be replaced after 60-70% of the tire is removed when the safety accident caused by tire burst is worried, the honeycomb-shaped high-pressure explosion-proof tire cannot explode and can be replaced by new tire after 80-100%, the tire core of the old tire can be repeatedly and conveniently used, the surface layer of the old tire is removed, and the new surface layer is injected into the injection molding die, so that the energy is saved, and the environment is protected.
5. Spare tires are not needed, and the installation of the tires is simple and quick: the tyre is not required to be inflated when being installed, and the spare tyre is not required to be placed on the automobile, so that the space is saved for the internal structure of the automobile, and the air leakage is avoided but worried about in the road. The tire is installed more simply swiftly, unscrews the set screw, opens annular compression piece, puts the tire into wheel hub and adorns annular compression piece fastening screw can.
6. Disaster prevention and reduction: when the automobile has a collision accident, many automobiles are emptied and tumbled, and the disaster degree is very disastrous. The condition is caused by the explosion of the air bag tyre and the inertia action of the vehicle running (the explosion is that one point of the air bag tyre is impacted and compressed, the reaction force is generated in the whole air bag and is concentrated and reacted on the impact point, the reaction force can give a strong elastic force to the tyre, and the tyre can empty the vehicle by inertia). And because the honeycomb-shaped high-pressure anti-explosion tire is of a honeycomb structure, only local reaction force acts on a collision point, and the excellent buffer performance of the tire does not generate strong explosion, so that the disaster degree can be effectively reduced.

Sixthly, the honeycomb-shaped high-pressure run-flat tire is characterized in that:
1. the appearance of the tire is not much different from the prior vacuum air bag tire, only a plurality of fixing screws are added, and the inflation door is omitted.
2. The internal difference is large, the vacuum air bag tire is a large space, and the inside of the honeycomb-shaped high-pressure explosion-proof tire is a small honeycomb-shaped space which is independent one by one.
3. Tire installation: the vacuum air bag tyre can be installed by means of wheel installation equipment and an inflator, and the honeycomb-shaped high-pressure explosion-proof tyre is formed by simply unscrewing a plurality of screws, detaching the annular compression sheet, putting the tyre on the inner cover of the wheel hub, and then screwing the fixing bolt.
Seventhly, manufacturing the honeycomb-shaped high-pressure run-flat tire:
1. preparation of fetal heart
The honeycomb-shaped strip is made of TPE (the diameter of the honeycomb is about 3cm, the thickness of the outer edge of a honey wall is 4-5mm, and the thickness of the inner edge of the honey wall is 3-4mm), the length of the honeycomb-shaped strip is equal to the perimeter of a tire core hub, the width and the height of the honeycomb-shaped strip are made according to the proportion of 35-40 of the flatness ratio, and the upper opening of the honeycomb-shaped strip is shown.
The TPE honeycomb strips were covered with a TPE sheet (approximately 3-4mm thick) of glue.
Glue is coated on the tire core hub and the TPE thin sheet, the roll of the TPE honeycomb strip adhesive thin sheet is adhered on the tire core hub to form a ring (figure 5), and then the tire core hub is heated (in order to ensure that the tire core hub, the TPE material honeycomb strip and the TPE thin sheet material are adhered into a whole after being hot-melted).
The method comprises the following steps of (1) stressing and binding a fetal heart strand and a TPE material honeycomb strip in a binding mode of taking five to stay five by using a steel wire mesh curtain (a strip-shaped high-strength steel wire and a nylon net, wherein the width of the steel wire mesh curtain is about 10cm, the mesh opening is 2mm to 2mm, and the diameter of the steel wire is 0.3mm), (the steel wire mesh curtain is used for shearing the steel wire mesh curtain at a bayonet and binding the steel wire mesh curtain with the TPE material honeycomb strip in a binding mode of taking five to stay five, and the steel wire mesh curtain is bound to the bayonet and is bound with the steel wire mesh curtain, the bayonet is reinforced by using an open net, and the fetal.
2. Tire injection mold making
The tire injection molding die is made of high-pressure resistant materials and has the functions of: the injection mold can simultaneously inject air (the steel needle on the needle fixing plate is pricked into the honeycomb hole for air injection through the hydraulic expansion piece) and inject liquid (the tire vulcanizing liquid tread is injected from the liquid injection hole), and the upper part of the injection mold is required to be engraved with tire patterns according to the tire patterns. The injection mould structure is shown in detail in fig. 8, 9 and 10.
3. Tire tread and pressure
The tire core is placed into an injection molding die, the structure of the injection molding die is shown in figure 7, the working principle is shown in figures 8, 9 and 10, the tire core and honeycomb holes in the tire core are simultaneously injected into the injection molding die (a hydraulic expansion piece inserts an injection needle into the honeycomb holes to inject gas or inert gas, note that the injection of tire tread vulcanizing liquid and the gas injection of the honeycomb holes are carried out synchronously), when the air pressure in the honeycomb holes and the injection pressure of the tire surface layer reach the balance (0.4-0.1mpa), the hydraulic expansion piece pulls the injection needle out of the honeycomb holes, and simultaneously, a liquid injection valve is closed. And (5) removing the mold after the tread layer is cooled, and finishing the tire manufacturing.
The key link of the whole tire manufacturing process is the design and manufacture of the injection mold, the injection mold design in the drawing is only used for explaining the manufacturing principle, and the injection mold is the key link when the tire is put into production and needs to be deeply designed again.
The tire surface injection layer and the honeycomb gas injection can be carried out separately, all honeycombs are injected simultaneously, the needle openings are simultaneously injected and repaired when the gas injection needles are pulled out (like the inner-injection tire repair), and then the tire surface is injected, so that the tire surface injection method is simpler (the air pressure balance is influenced by the possibility of gas leakage during the needle pulling), but the quality is not better than that of the prior scheme.
