    1467490 Bead cores for pneumatic tyres MICHELIN & CIE 6 March 1974 [7 March 1973] 10122/74 Heading B7C The bead core 8 of a pneumatic tyre is formed by winding a single, continuous elongate element of quadrilateral section about an axis, or by winding a ply comprising a plurality of side-byside elongate elements each of quadrilateral section about an axis. The element(s) may be of metal, plastics, or glass fibres, may have a section in the form of a parallelogram (e.g. a rectangle such as a square) a lozenge, or a trapezium (e.g. an isosceles trapezium) and may, when rectangular in section, have bevelled edges. The illustrated core 8 is enveloped by rubber packing 10, a rubber sheath 11, and is surmounted by a rubber filler 12. The rubber of the sheath is harder than that of the packing, and the rubber of the packing is harder than that of the filler. The radially inner face of the core may be parallel, or inclined with respect, to the tyre axis. Reference has been directed by the Comptroller to Specification 1,097,876.

    专利说明:

    The invention relates to the tire industry. A pneumatic tire bead is known, comprising a rubber filler coating that is integral with the seal and a carcass reinforcement wrapped around a side bag of package type 1. This bead ring is made in the form of a thread or ribbon wound in several layers on a suitable substrate. Despite their simple and economical design, pack-side airborne rings have two drawbacks. The first drawback occurs when the tire is introduced into a mold for molding and vulcanization: the threads move relative to each other over the cross section of the bead ring. In this case, a difference in stresses arises, which leads to the appearance of the second drawback, a decrease in tensile strength. The instability of the shape of the side beams of the packet type does not improve with the use of crimping clamps, since this does not eliminate the random arrangement of the threads between two successive clamps. When used, instead of ribbon threads, side rings of only square, rectangular cross section, or section in the form of a parallelogram can be obtained. But they have insufficient resistance to stresses arising from the formation of the flange. This is because the ribbons slide one over the other, since it is difficult to get a completely flat ribbon under mass production conditions. On the other hand, it is difficult to obtain a side ring with an inner conical wall from the tape, i.e. inclined relative to the axis of the side ring, and this is necessary, for example, for tubeless tires, the base of the bead which has a conical shape. Closest to the invention is a pneumatic tire bead containing a rubber filler, a coating that forms one piece with the street, and a frame reinforcement wrapped around at least one bead ring that consists of at least three layers superimposed on each other. filaments having a cross-sectional shape, an elongated quadrilateral with two parallel sides, and at least two sides of the filament of each layer are conjugated along the entire length with adjacent cTopofiaMH adjacent filaments in the radial and axial Regents x L2. However, such an arrangement of the tire bead also does not ensure reliable preservation of the shape of the bead ring during tire forming due to insufficient interconnection of adjacent rows of threads, which ultimately reduces the tire bead tightly. The purpose of the invention is to improve the pro-ring side and durability of the tire bead. This is achieved by the fact that, at least, one of the strands of the bead ring at the well-known bead side is connected with adjacent threads with all its sides. It is most preferable to perform the bead, in which the threads have in nonepeHHON; section, the shape of a rectangle with a cut edge, and the elongated sides of the threads are located in the axial direction. In general, the concept of an elongated quadrilateral with two parallel sides includes a parallelogram rectangle and a trapezium. The following options can be obtained: 1. The section of the thread can be. being right angle, the contact in the radial direction between two adjacent filaments is made on the large sides of the rectangle. The production of such yarns does not encounter difficulties, such a section is well suited for obtaining side rings of commonly used forms 2. A rib of a rectangular section can be light, beveled or rounded, but so that no large voids in the cross section of the side ring are created during winding. The presence of smooth edges without burrs contributes to a good fit of one thread to another. 3. The large sides of the filament of straight section can be inclined relative to the axis of the bead ring, i.e. relative to the axis of the tire. This gives the opportunity to receive rods of packet type with a parallelogram cross section. It is also possible to use a thread with a parallelogram cross section corresponding to the cross section and orientation of the side ring section, for example, relative to the bead support on the rim or relative to the tire axis. 4. For the manufacture of the initial nit, any material can be used, simple or complex, capable of being transformed in one way or another into the desired section. Usually the choice falls on cheap materials: metal plastics, synthetics, glass. 5. The tire bead may include one or more bead rings according to the invention in combination with one or more bead rings of other types. The advantage of the proposed batch-type bead rings is the ability to select the appropriate cross-section of the initial thread. This makes it possible to optimize and regulate the contacting and transfer of stresses between adjacent filaments, which is impossible to do with commonly used filaments. In the proposed side rings, the cross section takes up a smaller area and they are more dimensional-stable, since there are practically no cavities in them. Form stability causes the sides of the tire, the most consistent with the theoretical location. The reduction in tolerances leads to an increase in strength, which in some cases is twice as strong as the known side rings of the batch type. FIG. 1 shows the proposed tire bead; in fig. 2 - thread for the manufacture of the side ring; in fig. 3-5 are examples of cross sections of bead rings obtained from threads of different cross sections. FIG. 1 shows the bead 1 of a tubeless pneumatic tire, for example, size 11.00-20. The bead rests on the rim 2. The surface of the bead 3 is determined. The bead surface 3 is made conical. Around the side ring 4 superimposed layer of reinforcement-5 frame of the radially located cord. Along the flap 6 of the reinforcement layer 5, there is a reinforcing layer 7, the filaments of which are inclined relative to the radial direction. The side ring 4 consists of filaments 8 of rectangular section wound so that they form a section in the form of a parallelogram, the base of which is parallel to the base of the bead. Typically, the bead ring has a coating 9, which is integral with the seal 10. Above the bead ring, inside the fittings 5, there is a rubber filler 11, the stiffness of which is less than that of the seal gas 10. FIG. Figure 2 shows a section of a thread 8 with cut edges 12, Figures 3-5 illustrate other possible embodiments of bead rings of trapezoidal or parallelogram cross section. A characteristic feature of all variants is the fact that they contain threads 13-15, conjugated with adjacent jirJNC-i threads with all of their sides, a side ring consisting of ciajibiibix filaments of rectangular cross section with a base of 2 mm and a height of 1, 3 VM , has resistance at times
