20 points of the curve, in which the tangent to this curve is perpendicular to the axis of symmetry of the curve, to the axis of the wheel's appearance; Rg is the distance to the axis of rotation of the wheel from the equatorial points 399 of a curve in which the tangent to the curve is parallel to the axis of symmetry of the curve located tangentially to the bead ring passing through the equatorial points where the side surfaces of the tire are located at a maximum distance from one another, and the tangents drawn to the surface of the tire are parallel to the vertical axis of the tire and through reinforced edges of the breaker located at the height H, while the rim rim has a part parallel to the carcass section located It is opposite to the middle fiber of the reinforcement and connected by means of a section made in the form of a 3-shaped curve, with the rim socket and terminating at the outer end of the rim by curvature directed towards the axis of rotation of the wheel. In addition, the carcass reinforcement at the top of the tire is parallel to the rebar breaker; The S-shaped portion of the rim has one branch tangential to the rim socket, and the other branch, kasa. telnuyu to the rim rim, parallel to the site, located opposite the middle fiber reinforcement. Moreover, the edge of the rim is located above the upper part of the side ring of the tire. FIG. Figure 1 shows the meridian for the half section of the proposed pneumatic tire superimposed on the meridial half section of the known pneumatic tire having the same ratio H / B; in fig. 2 - a zone of a rim and a circular ledge of a rim of two pneumatic tires according to FIG. 1, an enlarged scale; FIG. 3 - the meridional profile of the proposed rim superimposed on a similar profile of the known rim with a circular ledge raised on 90®; in fig. 4 is a curve of the uniform distribution of the average fiber over a radial carcass deprived of the reinforcement of the upper part and subjected only to the inflation pressure; in fig. the measures of the dianal half-section of the set consisting of the proposed rim and the pneumatic tire; the pneumatic tire is represented in the inflated state (solid lines) and in the inflated state under load (dashed lines); in fig. 6 is a variant of the kit shown in FIG. 5 with a pneumatic tire of the same size Ne B, but with a rim, less wider than a CIM than the rim of FIG. 5 (the drawing is limited by the representation of the flange and the circumferential protrusion of the rim of this set). FIG. 1 and 2, numbered references are labeled with index 1 when it comes to pneumatic tire and / or rim, which are commonly used. Elements that are common to two pneumatic tires and / or rims are also used to denote index numbers. In addition, the proposed elements are indicated by solid lines, and known elements are indicated by dotted lines. FIG. 1 shows half of the meridional section of the proposed pneumatic tire and half of the known tire. Each of these pneumatic tires includes reinforcement 1 and 1.1 of the radial carcass represented by the middle fiber side cod 2 and 2.1 of the tire, belt breaker 3 supporting the protector k, the frame 1.1 of the carcass is rotated around the side ring 2 and 2.1 of the tire in the outermost rim. It covers the reinforcement profile of the breaker 3 identical for both pneumatic tires. The armature of these pneumatic tires is covered with rubber on all sides and is directly tread, the side surface 5 and the edges 6 and b are also covered on top. one . In the rim of the rim, the carcass reinforcement of the proposed pneumatic tire, without changing its concavity, touches the point 7 of the side ring 2 of the tire to wind around it. Starting from the point 7 of average bending, the reinforcement 1 of the frame is connected to the reinforcement of the breaker 3. In FIG. 1, the average bend is directed (dashed lines) near the shoulder in order to pass tangentially under the breaker reinforcement 3 and move away from the middle curve of the uniform distribution shown by the thick dashed lines. In a known pneumatic tire, on the other hand, the armature 1.1 of the carcass changes the concavity at point 8.1 approximately at the level of the flange in order to be able to twist around the side ring of the tire. Starting from point 7.1, where it touches the side ring of the tire, prior to insertion of the breaker 3 under the reinforcement, the frame reinforcement 1.1 has an average curve that deviates from the curve of the proposed pneumatic tire, namely, in the lower part of the side surface of the pneumatic tire. The rims corresponding to these two pneumatic tires are shown in FIG. 1 only by external contours and 9.1 parts of the above-mentioned rims with edges 6 and 6.1. Thus, it can be seen that these rims are different in the outer part, starting from the nest of the edges. In particular, the rim 10 of the proposed rim includes an inclined part strictly parallel to the segment located in front of the middle fiber of the proposed pneumatic sheath. Thus, the proposed pneumatic tire achieves a deforming deflection and a load identical to the load and deflection of a known tire, with a lower inflation pressure, while at the same time ensuring greater transverse rigidity. Moreover, it has the best characteristics in terms of convenience, strength of wheel adhesion and stability. FIG. 3 is shown in detail in the external profiles 15 and 15.1 of the proposed and known rim, which are suitable for the pneumatic tires shown in FIG. 1 and 2. Profiles 15 and 15.1 are distinguished by their outer parts 1 to slots 12 flanges and depth of the bottom of the notch 16 and | 1b.1. The rim of the profile 15 has a nest 12 extended by an S-shaped curve 17, the branch of which is adjacent to the nest 12 meets the rim of the pneumatic tire rim (not shown) and the outer radial branch is connected to the sloping part of the curve 17 of the circumferential rim flange. The slope of curve 17 ends in a bend 18. The profile 15 of the proposed rim differs from the known one. In FIG. Figure 1 also shows elements characterizing the sides of the meridional part of the proposed pneumatic tire, where H is the height, B is the width, CD is the width of the rim, shown through the axial distance between the extension point 11 of the extension of each of the two slots 12 and the tangent 13 at the upper end of the curve H which connects these sockets with each rim flange. The table shows the comparative results between two pneumatic tires (sizes DR50-15 according to the standards of Tir & Rome Assoshajted) with the known and proposed carcass profile. profile 15.1 rounding t9i intended for rim flange. But they may differ, starting from flange jacks 12 or even having jacks 12 that are different in width and inclination. Profile 15.1 has part 17.1 with an inclination angle of 90® relative to the axis of rotation, and then ends with a bend 18.1. According to the invention, the circular rim kit , has a radial elongation below the circumferential protrusion (I5f 17.1, 18.1) of the known rim. The reduced height of the circumferential protrusion of the proposed rim and its specific profile facilitate the mounting of the pneumatic tire in view of the possibility of increasing the diameter of the bottom of the rim 16 relative to the diameter of the bottom 16.1 of the known rim. Thus, the invention makes it possible to increase the unoccupied space inside the rim. FIG. The middle fiber of a single radial carcass is shown, which is subjected to the inflation pressure of the median axis of rotation. frame, (pneumatic tire), as well as the equatorial axis, connecting points E, where the frame reaches its maximum width and has tangents parallel to the median axis. Equatorial axis is parallel to the axis of rotation. The two branches of the middle fiber are connected at the top of point A and interrupted at point C, these points A and C are located on the median axis. At the top point A, the two branches have a common tangent parallel to the axis of rotation. In addition, at the point D- ,, respectively, Oh, each branch has a different line / gel, parallel to the axis, taken. FIG. L is also represented by the radii Rg and RS of the equatorial points E and E 2 and the upper point A. The average wavelength has a bend radius, defined by the formula. The segment length is normal tangentially to the neutral fiber at point M, defined by the distance between this point M and the equatorial axis E, E2, equal to L, which is determined by the formula / il. L1 I, fj-v Ke In FIG. 5 and 6 show examples of the proposed pneumatic tire, one (FIG. 5) is provided with a wide rim, the other (FIG. 6 is narrower, the middle fibers 20 and 21 of the frame of the inflated pneumatic tire, which is mounted on a special rim, are also shown, as well as professionals / m 22 and 23 medium fibers, considered under the influence of pneumatic deformation, corresponding to 21% of the height H, similar to the pneumatic tire defined above.Two pneumatic tires have, besides torOj, the same height on the rim H, maximum width B of the carcass, diameter D baud and breaker armature 2, they are designed to transfer the same loads. These pneumatic tires differ in width ld (Fig. 5) and UQ (syig.b width UQ is less than the width LQ of the rim on which they must be mounted. As a result This difference decreases the transverse rigidity of the pneumatic tire in Fig. 6. Structurally, this is expressed through the increased length of the frame 21, greater than the length of the frame 20, and through the tangent to, the contact point 2C with the bead ring of the tire 25, less inclined in relation to rotation axis. The pneumatic tire in FIG. 6 provides a greater range of application, which is incorporated in the invention, and especially in the lower zone of the framework. FIG. 5 also shows that the circular protuberance portion 26 of the rim 27 is parallel to the segment corresponding to the middle fiber of the carcass and is strictly linear. FIG. 6, on the contrary, the corresponding part has a concavity directed inward of the pneumatic tire. However, the set of the circular protrusion from the rim 28, shown in FIG. 6, larger than that shown in FIG. five; This is done by the consolidation of the rim, the width of which LO is reduced in relation to the width LQ corresponding to the pneumatic axis of FIG. 5. In both cases shown in the drawings, the value of the ratio of the height li of the circumferential protrusion of the rim 27, 28 to the radius r of the final curvature of the circumferential protrusion of the rim is satisfactory and is between 1.5 and 2.5. The proposed device in comparison with the known provides greater flexibility of the tires, thereby increasing the smoothness of the vehicle, durability and improving its stability. Claim 1.
