In General, the present invention relates to equipment drive vehicles.

If to be more precise, the invention relates to a bus that contains a sealed rubber shell and reinforcement structure, formed mainly by the many located several layers of fibers, each of which is separately filled rubber.

Characteristics of the modern pneumatic tires, in particular, with regard to their durability, impermeability and durability, currently achieved at the expense of increased complexity as the physical construction of these tires, and ongoing stages and operations for their manufacture.

In this context, the aim of the present invention is a tyre that at equal performance would have a more simple structure and was simpler to manufacture than a modern bus.

To this end, the tire according to the invention and, in addition, in accordance with the General definition given in the above introduction, mainly characterized in that the reinforcing structure formed by the carcass layer, brakeman layer and the connecting means, and the fact that each fiber layer frame forms with the median plane perpendicular to the axis of the tire, the first angle of 75° to 90°, and the fact that every fiber brokerage SL is I forms with the median plane of the tire, the second angle, of 0° to 15°, and that the connecting means connecting the fiber layer frame and brokerage layer, and that at least each of some of the fibers of the reinforcement structure has a fully United, flat shape cross section and includes spaced at right angles to each other of the first and second dimensions, the first (or thickness) is less than the second size (or width) and is located essentially in the radial direction of the tire.

In that case, if the first angle is 90°, then each fiber, oriented according to this corner, is thus located in the Meridian plane of the tyre, i.e. in the plane passing through the axis of the tire.

It should be recalled that the fully connected surface is a surface, any two of which mandatory interconnected.

As an example proving the opposite fiber with a fully connected cross-section may, in particular, to lead cables with many twisted lived the same type that are typically used in the amplifying structures tires, and the cross-section of the cable of this type is formed by placing adjacent cross-sections of various veins that make up the cable, each of which does not depend on the other and is of selfreliance is positive relative to the cable.

In addition, the term "radial direction" in this case is defined as an overarching direction, which simultaneously fits in the Meridian half-plane extending from the axis of the tire and passes through the center of the line in this Meridian half-plane essentially toroidal internal volume bounded by bus.

In other words, the thickness of each fiber having a flattened cross-section, elongated, thus, according essentially to the normal direction of the tire of the bus.

The invention is based in fact on the discovery of the fact that in contrast to their preferred and well-known mechanical properties of multi-conductor cables currently used to provide rigidity in the pneumatic tire, could also contribute to the emergence of adverse events, and the complex nature of the design of modern pneumatic tires just due to the need to reduce these phenomena.

In particular, multi-conductor cables having a generally round cross-section, have the ability to provide strong opposition to the efforts of the tension resulting from the internal pressure in the tire, and easily bend to ensure deformation of the pneumatic tire in contact with the ground.

On the other hand, if each cable is individually well-filled resi is Oh in the bus the rubber does not penetrate into the middle of the cable, resulting in none of the wires of the cable separately not filled rubber, and the cross-section of the cable, thus, is not fully connected form.

As a result, the cable, in particular, serves as a guide element of the release of any liquid and gaseous media that may fall on him, such as air contained in the tire, and moisture in the case of a cut of the latter.

In addition, any bending of the cable is necessarily accompanied by relative longitudinal movement between a lived past with the advent of friction between the surfaces in contact of these lived with each other or the occurrence of shear strain of rubber tires in the absence of contact, and each of these harmful phenomena is undesirable.

Providing that at least some of the fiber amplifier designs are fully United and flattened cross-section, the invention allows to increase the tightness of the tire, and to reduce mechanical fatigue of the latter.

Fiber with flattened cross-section have, for example, a width and a thickness, the ratio of (first and second) is equal to at least five, and this section may, in particular, to make a rectangular, oval or ellipsoid shape.

With the possible according to the method of the invention, at least each of several fibers with flattened cross-section formed by a single fiber.

However, it is also possible to provide that at least some of the fibers with a flattened cross-section were formed of multiple fibers that are essentially parallel to each other and are embedded in the matrix, ensuring the integrity and cohesion of the fibers.

In all cases, each fiber with flattened cross-section is preferably made of a material (composite or decomposing), having a modulus of tensile elasticity, which is from 3 to 250 HPa, with every fiber brokerage layer has a modulus of tensile elasticity equal to at least 30 GPA.

Preferably between the fibers with a flattened cross-section of each layer contains (in each layer) different from zero period, which is less than 2 mm and, for example, equal to at most 1 mm

Fiber with flattened cross-section can be made of a material selected from a set containing steel, aluminum, glass, a polymer belonging to the group of polyester, polyethylene, polyamide, aramid or polyvinyl alcohol, a composite material formed by optical fibers or polymer, recessed in the resin, in particular a composite material of p is lietilena fibers, glued with resorcinol-formaldehyde-latex.

According to a possible implementation of the invention the connecting means include connecting layer placed between the carcass layer and brakeman layer and connecting them with each other.

Preferably the material forming this connecting layer has a secant modulus strain at 10% strain, equal to at least 50 MPa.

In particular, the material forming this connecting layer may include polyester, epoxy resin, or a material with zechusim modulus strain at 10% strain, equal to at least the module stretching polyester or epoxy resin.

However, it is appropriate to provide that the material forming the connecting layer, had the secant modulus, strain at 10% strain, equal to a maximum of 300 MPa.

According to another method of implementation, the connecting means can, at least, contain junctions, providing a direct and personal connection fiber with flattened cross-section layer frame with every fiber with flattened cross-section brokerage layer and the carcass layer and brokery layer, thus together form a net structure.

In that case, if the fiber with flattened cross-section layer frame and brokerage layer made of to positng material, formed by fibers embedded in the first and second resin, the joining is preferably formed by connecting the second resin fiber layer frame and the second resin fibers brokerage layer.

According to the method, which easily can be applied in industry, brokery layer can be formed by winding around the circumference of the tape, the various coils which represent different fibers of this layer.

To provide adhesion reinforcing structures, for example, provides, inter alia, that every fiber layer frame was bent and kept their two ends to the respective circular wire rings of the tire, thereby increasing the corresponding inner side of the tire.

In addition, brokery layer preferably is a layer around the frame and in a limited area, essentially parallel to the tread.

Other distinctive features and advantages of the invention will become clearer from the following description, which is illustrative, but not restrictive, with reference to the accompanying drawings, on which:

- figure 1 is a partial perspective view image of the inner part of the tire in accordance with the method of the practical implementation of the invention, according to which the connecting means include with the uniting layer;

- Fig.7 is a perspective view brokerage layer for a tire according to the invention, this layer is made by spiral winding of the tape and cut along its edges.

As previously reported, the invention relates to a pneumatic tire, considered mainly from the point of view of its structure.

W is 1, as a rule, comprises a sealed rubber shell 2 and amplifier design, formed mainly by multiple fibers that are individually filled rubber and are arranged in several layers.

Rubber and reinforcement design contribute to defining the sides of the tires 11, through which the tire is mounted on the rim, the tread 12, to which the tire rests on the road, and side walls 13.

Rubber 2, which in General is not uniform throughout the mass of the tires, but on the contrary can be adapted to a variety of operational assignments, the implementation of which it must provide at various locations occupied by it in the bus, consists mainly of mixtures on the basis of rubber, which are administered by various well-known specialists fillers or additives.

In the tire according to the invention the reinforcing structure to form a carcass layer 3, brokery layer 4 and the connecting means 21.

The carcass layer 3 can generally be placed simultaneously under the protector 12 and under sides 13 of the tire.

Each of the fiber layer 30 of the frame 3 is held, for example, with their bent ends on the side of the wire rings 5 having, for example, a round cross-section, which amplify, respectively, the right and left tire bead 11 bus.

Fiber 30 of this layer frame 3 is formed with Meridian PLO is bone P, perpendicular to the X-axis of the tire, the first angle A1, as close as possible to 90° and at most equal to 75°.

As shown in Fig. 1, 5 and 6, with regard to brokerage layer 4, it is around the layers of the frame 3 (but preferably only in the restricted area under the tread 12, remaining essentially parallel relative to this tread.

This brickery layer can be formed mainly by multiple fibers 40, as shown in particular in Fig. 1, 5 and 6.

However, this brickery layer may also consist mainly of single fiber 40, folded in the form of a loop, spanning the width or at least the greater part of the width brokerage layer 4, and it is the only fiber forms, thus the ring.

Every fiber 40 brokerage layer 4 formed with a Meridian plane P of the tire, the second angle A2, also as much as possible close to 0° and at most equal to 15°.

This angle A2 is shown in figure 1 between the line OP median plane P in the plane perpendicular to this plane P, and a rectangular projection 040 (on this perpendicular plane to the axis of symmetry of the fiber 40.

The task of connecting means, which may take a variety of forms of practical implementation, in particular, the practical implementation of the connecting layer 21, is the connection between the fibers 30 and 40 layers of the frame 3 and brokern the layer 4, in particular fixing the relative angular position of the fibers 30 relative to the fibers 40 or fibers 40.

In addition, the reinforcing structure formed by the layers 3 and 4, contains fiber, each of which has a fully United, the flattened shape of the cross section.

Further in the present description is hypothesized that each of the layers 3 and 4 contains many fibers, respectively, 30 and 40, and each of these fibers 30 and 40 has a fully United and flat shaped cross-section, with this situation, the corresponding preferred way of practical implementation, however, is not required.

The connectedness of the cross section of each of the threads 30 and 40 determines in this case the peculiarity of this section to be submitted in the form of a single unit or more in theoretical terms represent a fully connected area in the topological meaning of the expression.

In order to do this, each of the fibers 30 and 40 may be, for example, formed by a single fiber, in particular a fiber made of metal, metal alloy or polymer.

Any two parts of the fiber cross-section belong therefore to the same mass, formed from the same material.

However, each of these fibers 30 and 40 may also be education is about a lot of metal, textile, glass or polymer fibers are essentially parallel to each other, and these fibers embedded in the matrix, have the task to ensure the integrity and cohesion of the thread.

Thus, any two parts of the fiber cross-section, at least, are interconnected by means of a matrix.

Prelusory shape of the cross section of each of the fibers 30 and 40 in this case is determined by the fact that this section has two mutually intersecting at right angles size, the first of which, called "thick", is less than the second, called "width", and the thickness is located essentially in the radial direction of the tire.

If only she will be flattened, the cross section of each of the fibers 30 and 40 can take any shape and may have, in particular, rectangular (figure 2), oval or elliptical in shape.

For example, the ratio w/t of the width w of the cross section of each filament 30 (2 and 4) to the thickness t of the same section may be equal to 5 or greater than 5, and the same range of values may be applied to the ratio wz/tz width wz cross section of each filament 40 (figure 2) to the thickness tz of the same section.

Preferably, each of the fibers 30 and 40 may be made, in particular, composite or decomposing material having a modulus of tensile elasticity, comprising from 3 to 250 HPa with every fiber 40 brokerage layer has a modulus of tensile elasticity, equal to at least 30 GPA.

These fibers 30 and 40 can be made of a material such as steel, aluminum, glass, a polymer belonging to the group of polyester, polyethylene, polyamide, aramid or polyvinyl alcohol, or a composite material formed by optical fibers or a polymer filled with resin.

In other words, each of the fibers 30 and 40 may be formed from one isotropic or orthotropic material (the latter, for example, is obtained by orienting the molecular chains of extruded textile fibers or fibrous rolling steel) or may be formed of a composite material of fibers embedded in a matrix, preventing any relative movement of the fibres, other than movements resulting from shear deformation of the matrix.

In all cases, the fiber (outside view) is a sealed tape.

Two examples of composite materials are, on the one hand, CVR (a composite material of glass fiber and resin) and, on the other hand, the polyethylene fiber (PET), combined into a single fiber by gluing using a resorcinol-formaldehyde-latex (RFL), i.e. bonding using the first or second, and the first ensures adhesion of the fiber filament, and the second, on the basis of latex, produces with the Association between the first and rubber tires.

In addition, the adjacent fiber layer 30 3 contain between a non-zero amount of preferably less than 2 mm, and, for example, at most equal to 1 mm, the same rule can be applied to the adjacent fiber layer 40 4.

Figure 1 and figure 6 shows the way of practical implementation, according to which the connecting means include connecting layer 21 having a thickness of ti (figure 2), which is located between the carcass layer 3 and brakeman layer 4 and connects these layers 3 and 4.

This connecting layer 21 is preferably made of a material that has zechusim modulus strain at 10% strain, equal to at least 50 MPa without however exceeding 300 MPa.

The material from which is formed in this connecting layer 21, may, for example, include polyester, epoxy resin or a material having zechusim modulus strain at 10% strain, equal to at least the module stretching polyester or epoxy resin.

According to another method of implementation, depicted in figure 5, the connecting means mainly or solely with established places of connection, directly and individually connecting the fiber layer 30 of the frame 3 with the fibers 40 brokerage layer 4.

According to this way of practical implementation of the carcass layer 3 and brokery layer 4, the thus, the together form a net structure.

If the fibers 30 and 40 layers, respectively 3 and 4 are made of composite material formed from fibers embedded in the first resin, the compounds may be preferably formed of the second resin.

When these fibers 30 and 40 are made of composite material formed from fibers embedded in the first and second resin, the compounds preferably can be performed by connecting the second resin fiber layer frame and the second resin fibers brokerage layer.

In particular, if the fibers 30 and 40 are glued with resorcinol-formaldehyde-latex on the inside of the fibers 40 may be used linking agent, such as isocyanate, for connection of the second resin fibers 30 and 40.

In that case, if the fiber is made of steel, these fibers before gluing preferably can be covered with a thin layer of brass.

Regardless of the chosen solution can connect to each other of the layers 3 and 4 brickery layer 4 can be formed, as shown in Fig.7, by spiral winding around the circumference of the tape, and the various turns of the tape form, thus, different fiber 40 that layer 4.

In this case, the wider the tape, the greater the angle A2 formed by the thread bergerova layer 4 with median plane P of the tire.

In this case, it may be useful to do this by cutting beveled edges on the edges of the spirally wound ribbon to make these parts fit into the corresponding plane parallel to the median plane P.

The dimensions w and t of each of the fiber layer 30 of the frame 3, and the step of laying down these fibers depend on many parameters of the design, material and operating conditions of pneumatic tires.

The greater the width w of the fiber 30, the smaller the fiber will have a tendency to bend in the direction of the tire circumference, however, the higher capacity of this tire torque to be transmitted.

However, the identity of all sizes, the higher will be the modulus of elasticity and the maximum allowable voltage forming the fiber material, the less can be selected thickness t.

According to the method of implementation, given as an example, do not have restrictive in bus travel vehicle according to the invention with a size of 205/55R16 for the formation of fibers of the layer of the frame 3 can be used a steel tape having a width w equal to 0.7 mm, the thickness t equal to 0.09 mm, and a tensile strength equal to 2800 MPa, and these fibers are placed on the side of the wire rings 5 with a step of laying equal to 1 mm.

Dimensions and tz wz each of the fibers 40 brokerage layer 4, is also the step of laying down these fibers, in turn, depend on many parameters of the design, selected materials and operating conditions of pneumatic tires.

Although the schematic diagram of the action is mostly common for schematic diagrams of the actions layer frame and can be practically implemented by specialist conservation amplifier design, description and illustrations which have been given special attention should be paid to the distance dz in brekina layer 4 between the two neighboring fiber 40.

In order to ensure maximum strength of the neighboring fibers 40 can communicate with each other in the Central part of the tread that leads to the establishment of zero size dz.

In that case, if the connecting means include a special rubber layer 21, the characteristics of this rubber layer is also taken into account when selecting the width w and wz fibers 30 and 40 by means of connecting layers 3 and 4, the main module of this rubber and the thickness of the ti, which is constant around the circumference of the tire, but may vary in the same Meridian plane of the tyre.

Indeed, the connection layers 3 and 4 is mainly produced by all the rectangular areas with dimensions w and sizes wz, where rubber 21 simultaneously connects on one side with a layer 3 and the other side with a layer of 4.

To achieve high the first resistance to the withdrawal of the tire, it is preferable to choose a smaller number of zones with large dimensions w and wz, the greater the number of zones of small dimensions w and wz.

Resistance to the withdrawal could be achieved simply by increasing the width of the fibers 40 brokerage layer 4, for example, up to 80 mm, in the center of the breaker bus for steel fibers.

As shown in Fig.6, brokery layer 4 can be formed on the edges of, i.e. near to the shoulder areas of the tyre, fibers 40a, a width less than the width of the fibers 40, which takes closer to the median plane P of the tire position.

In addition, the external fiber 40a preferably can be made of more flexible material, such as aramid, if more internal fiber 40 is made of steel, and this location allows you to optimize the stability of the tire to deform in the area of fiber 40a.

Internal fiber 40 brokerage layer 4 shown in Fig.6, in turn, can be formed by respective rings, in this case in the amount of four units, or by winding the only tape the top of many turns, in this case four, as shown in Fig.7.

In addition, when the practical implementation of the bus can be applied to more simple way than in the exercise of currently known tire, the tire according to the invention is easier and more cost effective than the last.
