And PROCESS OF PRODUCTION

The present revendication of the invention patent is based on the descriptive report to follow; to mold a piece of the MICROCELULAR polyurethane of isocyanate composed and poliol POLYETHER or specific polyester. This molded, can be able of elastomer, plastic, expanded plastic, natural rubber, synthetic rubber, expanded rubber, vulcanized rubber, neoprene, EVA, silicon rubber, natural cork, pressed cork, agglomerated cork, cork with plastic, cork with rubber, expanded cork, cork with vegetal fiber, or cork with synthetic fiber. This piece, called model, when produced mainly of rubber, will be able to have the format, in its interinal, of BEEHIVE with geometric form, cylindrical, triangular, square, rectangular or lozangulo. This beehive could be open or be filled with cork, EVA, microcellular polyurethane, plastic expanded, elastomer or wooden dust (serragem). The piece molded, called model, could be an expanded or compact block. When produced in cork, the model will be able to fill 100%, its mean, total the internal space of the tire. This molded piece will be coated by one second piece called, INVOLUCRE of silicon rubber, vulcanized rubber, neoprene, SBR, latex, natural cork, pressed cork, agglomerated cork or composed cork with rubber. In described format is in the scope of the invention. Optionally, it can be used blanket or fiber KEVLAR to coat the mold before inserting in the INVOLUCRE. The items mold, INVOLUCRE and optionally the KEVLAR, form an ONLY Piece that will be inserted to the interior of tire substituting partially air of the air.

STATE OF THE TECHNIC. The conventional tire, of any type and manufacturer, has as necessary use, of air to remain itself consequently inflated and, to absorb the impact to if atrition with the ground. When the TIRE is new has a band of wheel-work, an amount of satisfactory rubber that propitiates a bigger protection of the layer of the tire. Reducing, but not hindering the possibility of punctures. The natural consuming of the TIRE makes with that the layer is each displayed time more to the ground. Increasing gradually and significantly the risk of punctures and soon the emptying the air of the tire. The new or used TIRE still has as great factor of risk, the damage them produced for shocks in holes and that they are of bigger gravity. Being able to cause an accident of great ratios, also fatal, for fast loss of air and possibly of the loss direction. It continuous exists, the enormous difficulty and upheaval for the substitution of the pierced tire. Either in a highway, which had the intensity of the traffic, for any type of vehicle, or in the field with tractors, pilers, tows etc. for the distanced of a place appropriate to execute the repair. Another sufficiently disfavored classroom, in this aspect, is the deficient drivers, aged drivers, with cervical pathology. Also for some women, the exchange of a tire represents a situation of extreme consuming. In the cases of collective transports and regional load transports, state and interstate, a pierced tire represents risk of direction, risk of material security, risk of physical integrity and loss of important time. Being able, this situation if to aggravate in damages of high dimensions. In such a way material how much personal. In the attempt, if find a solution for this problem, to long of the years the some inventions, they had been developed. For example;

BULK TIRE - System highly weighed. It does not possess absorption to the shocks and compensation of pneumatic effort. Impracticable in all the directions, since the production, commercialization, assembly and utility. (11) (21) (MU 6100164) TIRE With additive liquid for barrier. Such the additive, when functional, so it only has capacity of closing a puncture small e in the set of wheel-work band. Lateral punctures, as well as shocks in holes do not get solutions with this system. (PI7904483)

TIRE With expanded polyurethane fulfilling. Such agreement of the invent, describes an artisan system extremely, since it is applied directly in the internal socket of the tire. Does not allow the variation of air of tire. Basic aspect in some cases. It is In-situ production. Being, the polyurethane molded in direct contact with the tire, the relation provoked attrition/ground, generates heat, and it is transmitted directly to the polyurethane molded. Moreover, the friction of polyurethane expanded during the use, still more provokes the cellular attrition increasing the heat on the molded. The cited factors generate the fatigue and the hysteresis of the molded of expanded polyurethane. Resulting in rupture and decomposition. (Pl 8304552) TIRE - With Elastomeric Protection. It is about a SHIELD of level G III (commercial term) is used currently by the companies of shield of vehicles. An elastomeric rubber brace is affixed to the hoop of the automobile of that, the tire, a pierced time, when emptying, can be supported by this brace. Preventing, of this form, that the tire-gear comes to get loose itself of the hoop and that the hoop ofl propagate it has direct contact with the ground. To, to keep the tire-gear in the hoop, this will allow that the vehicle can be lead in moderate speed (40 km/h) for one distance of up to 10 km (Pl 4,573,509) TIRE - Run Flat Tire (RFT); Manufactured for the BRIDGESTONE. In puncture case, it informs the manufacturer, the automobile will be able to circulate more for 80 km to a speed of up to 90 km/h. This tire, possess special composition in the walls (flanks) moreover have a one lager and strengthened tire-gear. What it suggests to understand itself for a harder tire. This system, demands still, according to norm of the manufacturer, who all the vehicles that come to use it, install sensors of accompaniment of pressure. TIRE - Pax System. This system was lassoed in 1998 for the MICHELIN and, it allows, according to manufacturer, to twirl with I propagate it up to 200 km with the tire pierced to 80 speed of km/h. Pax system uses a tire of vertical hook and is it does not separate the wheel. It has the shorter lateral band. Also have a elastomeric rubber that composes the system to the used in the cited shield previously as G III, to support the automobile in the case of loss of pressure. It uses, still, special wheel and system of accompaniment of pressure. In all cited systems, none possess the characteristic of to be resistant the puncture preventing the emptying the air of the tire. The main focus is to assure an, autonomy of circulation for plus some kilometers until the driver can carry through the exchange. SCOPE OF THE INVENTION: To mold a piece of MICROCELULAR polyurethane, isocyanate made up of and poliol POLYETHER or specific polyester. Being able, still, this molded to be of elastomer, plastic, expanded plastic, natural rubber, synthetic rubber, EVA, silicon rubber, having in its interior the format of open BEEHIVE. This open beehive can, still, be filled with microcellular polyurethane, EVA, elastomer, expanded plastic, cork or wooden dust (serragem). The molded, still can, to be of natural cork, pressed cork, expanded cork, agglomerated cork, cork with rubber, cork with plastic, cork with vegetal fiber or cork with synthetic fiber. This molded piece, will have the internal format of the tire and with the following characteristics: "A" of figure 2 - the internal lateral area of the tire from the set of wheel-work band. Occupies all until almost reaching the tire-gear. Being it enters 1 the 10 centimeters of the tire-gear, depending on the type of vehicle and the size of the tire. The molded can be in an only piece or can be produced in diverse pieces that ranks side by side complete all the circumference of the tire. The molded one, described, receives a layer said INVOLUCRE and, this can be of silicon rubber. It can be of vulcanized rubber, latex, SBR, cork with rubber, natural cork, pressed cork, agglomerated cork, cork with plastic, cork with vegetal fiber or cork with synthetic fiber ("B "of the figure 2). This layer, said INVOLUCRE, will cover the molded, produced mainly of microcellular polyurethane, vulcanized rubber or cork. This set, molded and INVOLUCRE, have circular format and in the internal part, or either, in the central space, it still has in the rubber layer of silicon rubber, vulcanized rubber, natural cork oak, cork with rubber, pressed cork, agglomerated cork, cork with plastic, cork with vegetal fiber or cork with synthetic fiber, sidewalls ("C "of fig. 2) that they form a socket ("D" of the figure 2), completing the invent it in an ONLY PIECE. Optionally it will be able, the molded, being is coated with fiber or blanket of KEVLAR before receiving the INVOLUCRE described and that ft can be processed of one time only, ("B "+" C "+" and "of the figure 2), in the case of industrial process. Thus speeding up the production perspective. This INVOLUCRE has for objective to protect molded done mainly of MICROCELULAR polyurethane rubber beehive, vulcanized or cork, against the direct attrition with the tire. Preserving the molded of the humid, the extreme heat and mainly it has the function to accumulate air in region "D" of figure 2. Thus allowing to the variation of air of tire and the perfect setting of the tire-gear to the hoop. This INVOLUCRE has "molded borders" ("E "of the figure 2), in order to establish total barrier of air. In this system air, besides correctly fixing the tire-gear ("F "fig. 2) to the hoop, has the extraordinary function to compensate the friction of the molded tire exerted on of MICROCELULAR polyurethane the beehive of rubber or cork, alleviating and reducing the consuming of the piece. The fact if gives, mainly, for layer "I" of fig. 2, this layer functions as a DIAPHRAGM and preference it will have an arched format "J" of fig. 1 , increasing the tension of force on the tire-gear. This means an extra profit in the performance and the durability of the SYSTEM. Finally, this ONLY PIECE, (Molded of microcellular polyurethane.vulcanized rubber beehive or cork, connected to the involucre) Figure 1 and 2 (transversal cut), could be commercialized of concrete form. As well as today a conventional tire is commercialized. This piece, reason of the present petition of pioneer patent, must specifically be produced for each type, model and size of tire. Thus, a tire 175/70 hoop 13, will only be able to use an appropriate piece, manufactured specifically for this model. The SYSTEM can, optionally to be fixed to the tire, glue or vulcanized, forming an only set, in accordance with the viability technic and commercial. The preference, this part will not be affixed to the tire. It will be inserted to the interior of the tire and at any time she could be removed of course. The main characteristic of this invent, is prevent the loss of air it tire in the perforation cases. Moreover the RESISTANT SYSTEM the PUNCTURES, prevents the sudden emptying the air of the tire on the any aspect. To the violent impact in a hole, the produced molded one, mainly, of MICROCELULAR polyurethane, rubber beehive or cork, will support the automobile preventing it the loss of the direction. Giving to the total conductor security until the procedure of the exchange of the tire. Ahead of a criminal obstacle, as a board of nail, the tire will become IMPONENT IN ITS Perform transposing the obstacle without any difficulty. Following, thus, its passage of course. The obstacle well be able reaches the four tires. Something impossible in the conventional system. Focusing bigger performance and durability of the RESISTANT SYSTEM the PUNCTURE FOR TIRE, can be used highly viscous silicon oil in the internal wall of the tire before installing the system. The silicon oil besides allowing a better fit of the system to the tire also goes to assist in the reduction of the attrition of the tire with invents it. The form of complementation to if installing the system. To if using the INVOLUCRE, produced mainly of vulcanized rubber, cork with rubber, pressed cork, agglomerated cork, or natural cork to coat molded with MICROCELULAR polyurethane, beehive of vulcanized rubber or cork, permit total protection the humidity, its becomes extremely easy extraction of the system the final consuming of the tire. This characteristic aims at to watch over for the final destination of the material used in invents it, inside of the norms of the environment.
