    专利说明:

    The invention relates to rubber pneumatic tires for automobiles having two bead wheels adjacent to the rim, in which respectively one ring core is laid around which a frame liner is placed in the rubber for fixing it, as well as to a method of manufacturing such pneumatic tires.
    The purpose of the invention is to improve performance by reducing weight and increasing bend elasticity.
    FIG. 1 shows an annular core, a cross section (embodiment); in fig. 2 is a section A-A in FIG. one; in fig. 3-6 ring core, cross section (embodiments); in fig. 7- rubber pneumatic tire, appearance.
    The ring core 1 (FIGS. 1 and 2) consists of an outer, stable-shaped profile ring 2, which is wrapped in this ring winding 3 of a thin coil material that forms a homogeneous mass in cross section and covering ring 4 in the form of a bandage. A frame insert 5 is wound around the ring core 1, the end 6 of which is held between the covering ring 4 and the winding 3. Moreover, the frame insert 5 lies on the full surface both to the outside of the profile ring 2 having rounded side surfaces and to the inside ring 2 to the winding, and the covering ring 4 with a certain preliminary voltage exerts pressure from the outside onto the end 6 of the frame insert 5 inserted into the profile ring 2, fixing this end on the ring core 1.
    The profile ring 2 on the entrance side of the frame liner 5 is provided with a curved horn shaped wall 7 located above, which protects the inserted end 6 of the frame liner 5 and ensures the winding of the frame liner around the ring core without the danger of bending.
    The winding 3 located in the core ring 2 substantially fills the cavity 8 formed by the core ring 2, so that the end 6 of the frame liner 5 lies flat against the winding 3 and passes to the horn-shaped wall 7 (Fig. 1).
    The ring core shown in FIG. 3, differs from the ring core shown in FIG. 1 in that it contains a winding 3 which fills the mold 8 of the profile ring 2 in such a way that 1 end inserted into the ring core 1
    6 of the frame liner 5 extends flatly in the ring core 1 with a slight inclination in the direction of the horn-shaped wall 7 of the profile ring 2, and also that the covering ring 4 is conical and has a profiling 9 in the form of a protrusion that matches the type of drop-in connection with the outer end of the wall 7 profile ring 2 and thus
    0 forms a connection with a geometric closure between the core ring 2 and the covering ring 4.
    In the ring core shown in FIG. 4, the profile ring 2 in the zone of the river 5 s5 of the different wall 7 is provided with a top-extending elongation 10, which can grip the conical clamping ring 4, which for this purpose is located
    0 at the top of the wall 11. In this case, the profile ring 2 has radial cuts or splines 12 in order to improve its flexibility.
    Formed by profile ring 2
    5, mold 8, as in the embodiment shown in Fig. 3, is filled with winding 3. Winding 3 is wound mainly from a single thread or a skein, which can be formed from several threads.
    0 Almost infinite winding is obtained, which is free from stretching and due to ultra-thin cross sections of individual filaments is extremely flexible, so that the risk of breakage
    5 is very small, and the stability and reliability of the ring core is very high. Due to the fact that winding 3 is almost endless, there are no connection points that could lead to weakening of the material and an imbalance.
    The ring core 1 shown in FIG. 5, is made similar to the ring core according to FIG. 1, however, the covering ring 4 has a protruding
    5, the upper end of the horn-shaped wall 7 of the profile ring 2, the protrusion 13 and on the underside one or more protruding safety bulges 14, so that the covering ring 4 in a fully fitted state to the profile ring 2 in the direction of arrow A does not form a snap-fit connection with profile ring 2 and, accordingly, recorded from slipping.
    5 When mounting, first the end of the frame liner (not shown) wound around the annular core 1 is pulled in the direction of arrow B on the winding 3 located in the mulder 8 of the profile ring 2 until its end is close to
    the inner side of the wall 7 of the profile ring 2. Then the clamping ring 4 is slid in the opposite direction according to arrow A on the profile ring 2 and the laid end of the frame liner in order to press the end of the frame liner to the winding 3 like a clamping ring ring.
    According to the embodiment shown in FIG. 6, the ring core 1 has a profile ring 2, made similar to that shown in FIG. 1 shaped ring and forming a trough 8, in which there is a winding 3 of high strength filament or spinning material. On the entrance side of the frame liner 5 there is a horn-shaped wall 7 with a curved or arched contour, so that the frame liner 5 can be laid around the annular core 1 with a commensurate bend and, thus, its inserted end 6 lies on the flat top side of the winding 3.
    On the outer side of the annular core 1 there is a covering ring 4, which presses the inserted end 6 of the frame insert 5 with a certain preliminary voltage to the winding 3 which is located in the mold 8 of the profile ring 2 and thereby fixes this end. Between the covering ring 4 and the upper wall 7 of the profile ring 2 there is an opening 15 through which the outer end 16 of the inserted end 6 of the frame liner 5 passes. The outer end 16 is directed through the opening 15 in such a way that it runs parallel to the outgoing from the side surface tires section 17 of the frame liner 5 and passes in close proximity to him, as shown in FIG. 6
    When performing an annular core according to FIG. 6, the inserted end 6 of the frame insert 5 is particularly securely supported on the ring core.
    Poly- (2,6-dimethyl-1,4-phenylene ether) has been shown to be particularly suitable for a plastic-shaped ring.
    FIG. Figure 7 shows a finished rubber pneumatic tire 18, having an outer annular treadmill 19, passing on both sides to the arched side surfaces 20, an annular flange 21, which is designed to fit to the rim of the car and in which the proposed annular core is laid.
    The application of the invention allows to create a rubber pneumatic shinudd
    cars, which have ring cores in its sides, which are well and durablely connected to the tire material. Ring cores are lighter and have a more uniform shape than the known ones.
    In addition, by improving the flexibility of the beads, the handling of the pneumatic tire during installation is simplified, and
    0 the expense of reducing the required structural height of the frame support at the same height of the tire cross-section provides greater comfort damping when driving or at the same
    5, the ride height of the shock absorber decreases the cross-section height of the tire in favor of a larger rim diameter, respectively, a brake.
    To solve this problem is proposed in
    To use a rubber pneumatic tire, use a profile ring consisting of a pneumatic tire that chemically connects with rubber and contains a winding of high-strength fibers laid in it.
    5 The profile ring is made of a pneumatic tire compatible with a rubber viscous material, i.e. one that can be permanently combined with rubber so that it is possible not to be afraid of separation and rupture of the material between the tire material and the ring cores under the influence of the tire deformation during deflection that occurs during operation. The profile ring contains a winding of
    5 of coiled material that is wound endlessly, i.e. there is no joint that can cause an imbalance of the tire, since the winding is made of predominantly ultra-thin coil material or fibers when using first a liquid and later ironing means, such as liquid rubber, is placed in a stable shaped ring in such a way that it is a ring with the formation of
    5 non-expandable ring without the need for a durable joint of the ends of the material forming the core ring at the interface.
    This elastic, but not compressible matrix
    0 prevents filaments from moving relative to each other and thus provides sufficient internal strength of the fiber bundle.
    Winding-forming fibrous or
    5, the coil material can be a thread, a set of threads, a yarn, monofilament or a complex thread (from 6-20 threads), as well as a thread twisted from several skeins, or a ribbon. The winding should consist of a relatively large number of the most
    thin filaments and coils to give the annular core the necessary strength, flexibility and reliability. The stable bending of a rigid bend profile ring imparts the desired external shape to the ring core and protects the coil material wound into it from a direct bend load both in the radial and axial direction of the pneumatic tire, and the coil material provides the contraction of the core ring and the necessary stability against stretch.
    Advantageously, the annular core is provided with a coating that encloses the side of the profile ring, which is first open to wind the coiled material, for example, in the form of a ring, which may be tape-shaped. This coating is placed on the ring core after the coil material is wound in a profile ring. At the same time, the coating is predominantly at such a radial distance from the winding located in the core ring that the carcass liner of the pneumatic tire provided between them is fixed so that the carcass liner during the manufacture of the tire, namely during bombarding and vulcanization, can not turn off from the annular core. In this case, the coating can be connected to a profile ring with a positive fit, for example, due to a certain profile of the coating and / or the profile ring. The coating may be profiled, extending in the direction of the winding in the core ring, in order to provide a connection with a positive locking between the coating and the frame liner laid under it.
    The profile and covering rings, consisting predominantly of one-piece flat material, may also have passage openings through which the rubber material may pass. In this case, the covering ring may consist of a fabric or sieve ribbon.
    Advantageously, the core and covering rings consist of plastic with a density of 1.0-1.5 g / cm3, particularly preferably 1.0-1.2 g / cm3. In line with this, it is possible to completely abandon a metal for an annular core, such as steel.
    The coiled material wound into the core ring is predominantly high strength for stretching the filament or spinning material, for example, consisting entirely or predominantly of carbon or aramid fibers, and should have a density of 1.3-2.6 g / cm, preferably 1 , 5 g / cm3.
    In accordance with this, due to the use of thin filaments at a relatively low cost of materials, high-strength and at the same time flexible winding in a ring core is obtained, which gives the latter the necessary
    0 stability against undesirable extensions. The profile ring covering this winding, as well as the covering ring, protects this kind of filament or coil material, which can be highly sensitive to bending, from adverse loads that may come from the frame liner wound around the ring core, in particular during bombing. pneumatic tire
    0 during vulcanization treatment in a press mold for tire molding or during installation. If the individual components of the ring core consist of the above materials, the ring core has
    5 similar or almost the same density as a pneumatic tire rubber. In accordance with this, the ring core can not only be fixed in the corresponding bead of the tire firmly in relation to the separation, but also be introduced into the tire material without causing an undesirable imbalance, which all the time is established in the known ring cores due to mass concentrations due to increased density.
    According to a preferred embodiment, the profile ring forms a mold or recess type for receiving
    0 wound in it a fibrous or coil material. As a result, the coil material may be almost completely covered by a core ring, respectively, to a large extent.
    5 is shielded last from direct contact with a frame liner wrapped around the ring core. Outgoing from a frame liner stretching force or the like. it is largely transferred to the profile ring, which, due to its mulch-shaped form, prevents the harmful loads created by these forces on the bend in a wound fiber or coil material. In this case, the profile ring is shaped in such a way that the frame liner can be folded around its outer side, i.e. profile ring Has no sharp edges or corners that can lead to adverse loads.
    frame liner, its contour provides a gentle entry.
    In addition, the ring core can be designed in such a way that it can sufficiently fix the end of the frame liner that is laid around it, which reliably prevents the frame liner from reversely restoring the form of twisting during vulcanization in a tire molding machine. This option is especially preferred for steel cord frames such as, for example, used in truck tires, where the covering ring forming the type of bandage has a certain clamping effect on the end of the frame liner inserted into the ring core, which is achieved by appropriate dimensioning. daimeter of the covering ring and under known conditions of a certain profiling of the surface of the covering ring acting on the frame liner.
