Abstract

The invention discloses a tubeless tire and belongs to the technical field of transportation vehicle application. The tubeless tire comprises an open type tire body 1, a closed type airtight liner 2, nanofiber bullet-proof fabric layers 3, tire beads 4 and the like. The tire body of the tire is a tire body integrating the open type tire body 1 with the closed type airtight liner 2, and is of an O-shaped sectional structure. Compared with the prior art, the tubeless tire is superior to a tubed tire invented by French Michelin in 1895 in that an inner tube is omitted; the tubeless tire is superior to a tubeless tire invented by American Lichfield in 1903 in that the machining cost of the production process and the like is reduced. The tubeless tire has another characteristic that the two nanofiber bullet-proof fabric layers are added in a rubber layer of the tire, so that the damage resistance of the tire is enhanced. The tubeless tire can be applied to a light high-speed vehicle, and can also be applied to various medium and heavy vehicles. All air leakage channels of the tire are blocked up, so that a user needs not worry about the problems whether the tire is in lack of air and the like.

Description

A kind of tubeless tires

Technical field

The present invention relates to a kind of tubeless tires, in particular one both can omit the inner tube of a tyre, again can to improve production technology cost for realizing tire and wheel rim delicate joint, and reach the tubeless tires of its sealed tire internal gas pressure, the present invention also can be referred to as " become flat nowhere can the disposable tire of relieved use ", belongs to vehicular traffic applied technical field.

Background technology

Trace to its source, according to historical records, Puffer-type tube-tyre is the earliest applied on cycle wheel, in 1888 by Irish animal doctor---and Deng Lupu invents.Afterwards in 1895 by French inventor---An Delie. Michelin, by again wound change design, set up rim strip between tire and wheel rim within it, be suitable for the tire having the inner tube of a tyre used on automobile.But its shortcoming is: the outer wall of the inner tube of a tyre is attached on the inwall of cover tire, when the wheel long period operates, between its inside and outside tire, easily produce oscillatory disturbance friction, cause and elevate the temperature and the accident such as to blow out happens occasionally,

The tubeless tires of prior art consolidated the inventor of special company in 1903 by the U.S.---Litchfield is invented, be applied on vehicle wheels, its technical characteristic is: under the condition that the cover tire Ω type profile of crude tyre (i.e. tube-tyre) does not change prototype substantially, eliminate the inner tube of a tyre.This technology must need the cost improving the aspects such as production technology, can say it is the extensive concern receiving people, China before and after 1985, many less tire production producers also all intend investment and to change the line of production this up-to-date technology, but because this technology requires too high to " degree of precision " of the aspects such as production skill, the cost of the aspects such as so corresponding production technology, will drop into higher than the cost of original tube-tyre far away.This technology has removed the inner tube of a tyre sealed, also to inflate in tire, section is made to be the carcass of Ω type, the position that it engages with wheel rim " if degree of precision " not high standard require, that does not ensure sealed tire internal gas pressure, thus people are also understood that, it is with high costs is also just this.Innovative design of the present invention be that the inner tube of a tyre of tube-tyre of the prior art and rim strip thereof are all removed, the inner tube of a tyre is transformed into the enclosed air-retaining liner that section is O type, be bonded in open type carcass, make tire carcass by the style of opening of Ω type profile, become the dead front type of O type profile, the tire carcass of its Ω type profile structure is made to become the tire carcass of O type profile structure, the tubeless tires of this structural type, within 1895, pacify moral with prior art to arrange. compared with the tube-tyre that Michelin invents, can be referred to as " structure is simple "; The tubeless tires of this structural type, compared with being the tubeless tires carcass of Ω type structure with the section that Litchfield in 1903 is invented, its advantage is: the cost that can reduce the aspects such as production technology.

Summary of the invention

The object of the invention is for above-mentioned the deficiencies in the prior art part, devising a kind of is by the inner tube of a tyre in tube-tyre, under its section is the immovable condition of O type structure, being transformed into a kind of enclosed air-retaining liner (i.e. rubber sealant) is bonded in cover tire, section can be made to be the tubeless tires of Ω type structure, to become the tubeless tires that section is O type structure.

Technical scheme of the present invention is: a kind of tubeless tires, it comprises: open type carcass 1, enclosed air-retaining liner 2, nanofiber ballistic cloth 3, tire lip 4 etc., described open type carcass 1, adopt rubber, chemical fibre, cotton, fiber crops, the composite material of metal filament etc. is made, and cross-section structure is the tire carcass of O type, described enclosed air-retaining liner 2, its outer wall is bonded on open type carcass 1. inwall, both formations are integrated, cross-section structure is the enclosed tire carcass of O type, described be bonded in enclosed air-retaining liner 2. on open type carcass 1. inwall it at the gauge of the non-bonding portion of open type carcass 1. opening part, be greater than one times of bonding portion gauge, or more than one times gauge, described nanofiber ballistic cloth 3, it is the one " nano-rubber alternating layer " combined together with the rubber layer in open type carcass 1., its quantity is two-layer, described tire lip 4, it is the sole site of tire carcass and wheel rim tight joint, the described enclosed air-retaining liner 2 be combined into one by the mode such as bonding and open type carcass 1., it is at any position of the cambered surface (i.e. the outer naked face of enclosed air-retaining liner) of the outer radius of the non-bonding portion of the opening part of open type carcass 1, all do not contact with wheel rim, there is a dead zone therebetween.

The beneficial effect of the invention: beneficial effect of the present invention has following 5 points,

One. the present invention is compared with the Puffer-type tire product of several kinds of prior art, its beneficial effect is: because namely tire itself is airtight, therefore, not only tubeless tires of the present invention, structure simply but also can reduce because tire engages the required productive costs improved with wheel rim technique high precision.

They are two years old. and compared with the band tyre that the present invention and prior art can only be used for low speed heavy-duty machinery, its beneficial effect is: in addition tubeless tires of the present invention, also can be applied on the vehicle of high speed of all categories.

They are three years old. compared with the product of the Puffer-type tire that tubeless tires of the present invention is of all categories with current prior art, owing to being provided with nanofiber ballistic cloth in carcass interlayer, the invention has the beneficial effects as follows, the attack of hard objects and sudden bullet etc. can be resisted.

They are four years old. and tubeless tires of the present invention is compared with the product of the Puffer-type tire of current several prior aries, owing to eliminating tire tube valve, again due to carcass inherently close, air pressure in tire runs off nowhere, and its beneficial effect is: application person need not worry the problems such as tire deflation.

They are five years old. and tubeless tires of the present invention, compared with the product of the Puffer-type tire of all categories with current prior art, because the gas of institute's pressurising in tire is nitrogen, its beneficial effect is: the composite material in carcass can not be oxidized.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is done with detailed description: the carcass that tubeless tires of the present invention can be seen in the accompanying drawings, by prior art French inventor in 1895---An Delie. the inner tube of a tyre of the tube-tyre of Michelin's invention, rim strip is removed, and its inner tube of a tyre to be transformed into section be that the enclosed air-retaining liner (i.e. rubber sealant) of O type structure is bonded on carcass inwall, defining section is the simple and direct of the wholly sealed of O type figure, suitable tubeless tires, its great advantage is just: the inner tube of a tyre which overcoming the tube-tyre of prior art contacts with cover tire, the bad phenomenon such as easy generation oscillatory disturbance friction is overheated occur, also overcome the tubeless tires of prior art Litchfield invention in 1903 simultaneously, the shortcoming that productive costs is excessively high.

The present inventor---An Fengwen goes through 38 years to prior art all size, type product is analyzed, research, reasoning, for some outstanding problems that prior art Related product is found in the application, the weak point of obvious some product of confirmation prior art, as far back as the wheel of the Sai Beier bogie of Hungary's import in chemical plant, Xinping, Shaanxi in September, 1974 because having an accident, the wheel rim of its 825 type tire is caused to be knocked, with the naked eye local deformation can be found out, maintainer asks a general requirements for instructions and changes, opened at that time and always said that accessory storehouse there is no this accessory, suggestion is tried out after managing reparation again, and say: check and get final product assembling test run as the inner tube of a tyre is harmless, afterwards, complete test run is assembled by its order, this match of result Bel's car liaison running always several years, until the unified all normal operations of scrapping of this kind use, if there is this kind of situation in the wheel rim as the tubeless tires of prior art Litchfield invention, the accuracy standard then engaging position with wheel rim because of tire carcass required the problems such as high, that just cannot continue and read to employ.

Example in sum, this is enough to the tubeless tires that prior art is described, not merely says the high cost problem of just production and processing, and also can often need to upgrade because slight change very easily occurs some relevant parts with regard to use procedure, the cost of use be obviously too high.

The present invention is in technology innovation design, for the structure that open type carcass is integrated with enclosed air-retaining liner (i.e. rubber sealant) bonding one-tenth, making its former Ω type profile carcass present the carcass of O type profile, is a kind of wholly sealed free from inflatable inner tube formula tire of high-seal.

The present invention be belong to tire carcass dispatch from the factory before the disposable product being filled with nominal pressure, inflation for it can be entrusted and be manufactured by its regulations for technical operation by without product professional production producers such as tire tube valve air bags, while matching with its wheel rim in the half-blank of its tire production, just sufficient air pressure, prenatal environment can be made more to weigh surely in order in application process for many years, in tubeless tires carcass of the present invention, institute's inflatable body is: not easily make material produce " nitrogen " or " unreactable gas " of oxidizing reaction.

At present, someone studies a kind of band tyre of application, but it and carriage velocity contrast are seldom, can not run at high speed, also can only be confined to apply on the engineering machine vehicle of high load capacity.And tubeless tires of the present invention, not merely can be: the middle and high fast heavy-duty vehicle of wheeled tank, rocket bogie, large-scale fire extinguishing tanker, breakdown lorry etc. is applied, and also can be: light-duty, the hot-short of medical truck, various racing car, various small passenger cars etc. is applied.And also overcome the weak point that prior art tubeless tires is confined to the application of medium and small, Light-duty Vehicle.

For prior art products, after reform pattern, up to standard in guarantee product design, on long-lived basis, owing to eliminating part raw MAT'L; Also due to the simplification to production technology programs such as high precision, especially by the tubeless tires of prior art Ω type profile carcass structure type, wound is changed to the original in style O type profile carcass structure of the present invention, wholly sealed tubeless tires, both raw MAT'L was saved, and also reduce production technology cost, be the behave for killing two birds with one stone.

It is quick that the present invention makes every effort to rhythm in conjunction with contemporary people for work and life, this overcritical hope time saving and energy saving, this technology of in good time release, have following functions feature: the present invention is except " hydrogen bomb ", " atomic bomb ", " guided missile ", " rocket projectile ", " great car accident ", the destructive attack of the force majeure such as extraterrestrial shock and " fire " and outer, tubeless tires of the present invention has possessed in peacetime, running under normality situation, can resist completely " iron nail " that come from road surface, the tip and hard object matter of " sharp stone " etc. and the attack of sudden bullet thereof, especially also deployed troops on garrison duty in the interlayer of wheel shoe and had two-layer nanofiber ballistic cloth, and with the more abundant rubber layer of its periphery, the effect of buffering also can be played for sudden bullet etc., the protection of multilayered barrier, the product of good effects, especially close prior art products easily to run off all channels of air pressure, stop application person's picture before using bicycle, first need to check and observe tire whether deficency, as autoists before not driving, be often go around around car, whether flatly have a look at tire ... if a kind of product can make people have forgotten such a complicated procedures in utilization process ... revolutionary approach of the present invention is moved, whether accord with " time saving and energy saving " of contemporary people, the vision of " convenient and swift "? also need each side's associated specialist, outer knowledgeable people is considered in the industry, assessment, research.
