    专利说明:

    [0001] The invention relates to radial carcass or cross-carcass tires. [0002] Radial-carcass tires have gradually imposed themselves on various markets, and in particular the tire market for passenger vehicles. This success is due in particular to the endurance, comfort and low rolling resistance qualities of radial technology. The main parts of a tire are the tread, the sidewalls and the beads. The beads are intended to come into contact with the rim. In a tire of radial technology, each of the main parts constituting the tire, namely the tread, the sidewalls and the beads, has functions well separated from each other, and therefore has a specific constitution well known. The radial tire is substantially reinforced by a carcass reinforcement comprising at least one carcass ply having an angle substantially equal to 90 ° with respect to the circumferential direction of the tire. This carcass reinforcement is surmounted radially on the outside, and under the tread, reinforcing plies forming a belt. The cross-carcass tire is distinguished from a tire of radial technology by the presence of at least two crossed carcass plies whose angle is different from 90 ° with respect to the circumferential direction of the tire. Tablecloths are said to be "crossed" because the angles are of opposite signs from one tablecloth to another. It is recalled that the circumferential direction of the tire is the direction in a plane perpendicular to the axis of rotation of the tire and tangent to the belt reinforcement of the tire, P10-3062 [0007] Following the appearance of the tire to radial carcass, some cross-carcass tires have also been provided with belt reinforcement under the tread. In both types of tire, the tread, in contact directly with the ground, has a particular function to ensure contact with the road and must adapt to the shape of the ground. The flanks, meanwhile, absorb the irregularities of the ground while transmitting the mechanical forces necessary to carry the load of the vehicle and ensure its movement. The belt reinforcement is an armature which must, on the one hand, be sufficiently rigid vis-à-vis the edge deformations so that the tire develops the drift thrusts necessary for its guidance, and transmit the engine torque or braking, and secondly, be very flexible in bending, that is to say allow variations in curvature of its plane to ensure a contact surface of the tire on the ground sufficient. Therefore, the belt reinforcement generally has a composite structure, allowing it to have the required rigidity for a relatively low weight. The belt reinforcement generally consists of at least two plies having different angles, comprising reinforcements, cable-shaped, coated with elastomeric composition. The reinforcing elements are crossed from one sheet to the other with respect to the circumferential direction and are symmetrical or not with respect to this direction. Hereinafter called: - "longitudinal direction": rolling direction of the tire, - "radial direction": direction intersecting the axis of rotation of the tire and perpendicular to it, - "axial direction": direction parallel to the axis of rotation of the tire, P10-3062 - "radially inner to": means on a straight line perpendicular to the axis of rotation of the tire, closer to the axis of rotation, - radially external to ": means on a line perpendicular to the axis of rotation of the tire, farther from the axis of rotation, - "equatorial plane or median plane": plane perpendicular to the axis of rotation of the tire and which divides the tire into two halves substantially equal, - "transverse or axial direction of the tire": direction parallel to the axis of rotation, - "radial or meridian plane": a plane containing the axis of rotation of the tire. It is already known from JP2293207 A tires for heavy vehicles comprising a carcass ply provided with metal reinforcements, the final part at each bead, is folded on itself, twice, in the radial direction towards the circumferential reinforcing element, also called rod.
    [0002] According to this document, this final part is folded in the middle of two layers of rubber. Also, there remains the need to have a tire having a better thrust, which comprises less raw materials, including less elastomer layers, and this without degrading the rolling resistance. The invention therefore relates to a tire comprising at least one carcass reinforcement comprising reinforcements, radially surmounted externally of a crown reinforcement S, itself radially on the inside of a tire strip. rolling, said crown reinforcement S consisting of at least one layer of reinforcing elements, said tread being connected to two beads by means of two sidewalls, said beads being intended to come into contact with a hook of rim having a rim hook top C, each bead having at least one circumferential reinforcing element, said carcass reinforcement P10-3062 comprising a final part at each bead, the final part of the carcass reinforcement being bent two once in a radially inner direction of the tire towards the circumferential reinforcing element, to bring an end of said final part close to the circumferentially reinforcing member so as to form a reversal of said carcass ply, said reversal comprising three adjacent portions consisting of a central portion, an axially inner side portion, and an axially outer side portion. The tire is characterized in that an elastomeric decoupling composition is present - between the axially inner lateral portion and the central portion of said reversal, and - on the radially outer end of said upturn, - said elastomer composition being present on a radial length between the radially outer end of the upturn and a point F radially internal to the upturn, located on the sidewall and remote from said radially outer end of a length greater than 10 mm, in that - the end radially upper of the upturn is disposed between a point A and a point D located at the surface of the sidewall, - said points A and D being arranged on either side of a point E on the sidewall corresponding to the nominal coil size said point A being radially internal to the point D, in that said point A having a projection A 'on a parallel axis YY' a radial direction ZZ 'and tangent to the flank at the point E, - the rim hook top C having a projection C' on said axis YY 'P10-3062 - said projection A' being disposed midway between the point E and the projection C ', and in that - said point D having a projection D' on said axis YY ', - said crown reinforcement S having a projection S' on the axis YY ', [0016] the tire according to the invention has the advantage of being simple and fast design. Preferably, the elastomeric decoupling composition is present between the radially outer end of said upturn and a point G located radially internal to said end and remote from said radially outer end of a length less than or equal to 10 mm. Preferably, a projection of the upper part of the overturning of the carcass ply on the axis YY 'is disposed between the points A' and E. [0019] A projection of the upper part of the overturning of the carcass ply on the axis YY 'is preferably disposed over a length 1 between -10mm and + 10mm, on either side of the point E, the point E having the value zero. Between the points A and D, the reinforcements of the carcass ply may have an angle less than or equal to 85 ° with respect to the circumferential direction, and preferably equal to + 75 ° or -75 ° relative to the direction. circumferentially. The angle of each part (central) and (lateral) of the carcass ply follows the rules of the following conformation law, according to which the angle of said parts changes with the radius of the tire: cos (ai) = tx cos (cto) where t = Ri / (R0 x (1 + e)) with - ao is the initial angle before conformation P10-3062 - ai is the final angle after conformation - Ro is the laying radius before conformation - R1 is the laying radius after conformation - e is equal to 0.03 whatever the tire [0022] By applying this law, between the points A and D, and when the folding takes place in the inner direction in the axial direction, reinforcements of the carcass ply may have an angle successively equal to -75 °, + 75 °, + 75 ° starting from the outermost direction towards the innermost direction in the axial direction. Between the points D and S, the reinforcements of the carcass ply may have an angle greater than or equal to 85 °, and preferably equal to 90 ° with respect to the circumferential direction. From the point S and in the direction of the axis ZZ ', the reinforcements of the carcass ply may have an angle equal to 90 ° with respect to the circumferential direction. The reinforcements of the carcass ply are preferably textile material chosen from rayon, nylon, polyester, aramid or their mixture. Part of the reinforcements of the outer portion of the carcass ply can be severed in the case of an internal rollover. Part of the reinforcements of the central part of the carcass ply can be cut in the case of an external reversal. This part can present about 5% of the reinforcements of the central part. According to the invention, the crown reinforcement comprises at least one ply radially outside the carcass ply and radially inside to a tread. According to the invention, no elastomeric composition is present between the central portion and the axially outer lateral portion of the upturn. The invention will now be described with the aid of the following examples and drawings, which are given by way of illustration only, and in which: FIG. schematically, the section of a pneumatic half according to the invention in a radial plane, according to a first embodiment; [0031] FIG. 2 is a diagrammatic and enlarged sectional view of the radially lower portion of an upturn of the carcass ply situated in the so-called low zone of the tire, according to the same embodiment of the invention. than that of Figure 1; - Figure 3 shows schematically, enlarged and in section, the radially lower portion of a reversal of the carcass ply, located in the so-called low area of the tire, according to another embodiment. In the different figures, identical or similar technical elements bear the same reference. Their description is not repeated so as not to weigh down the text. As shown in Figures 1 and 2, the tire according to the invention of general reference 1 comprises at least one carcass reinforcement 2 comprising reinforcements (not shown). A crown reinforcement S 3 comprising at least one reinforcing element layer (not shown) is surmounted radially inside the carcass ply 2, then a tread 4 radially outwardly. The tread 4 is connected to two beads 5 through two sides 6. Each bead 5 comprises a circumferential reinforcing element 7, also called rod. Each bead 5 is embedded in a rim hook 13 comprising a top hook C of j ante. The carcass ply 2 comprises, at each bead 5, a final end 8 folded on itself twice in the radial direction and towards the inside direction with respect to the center of the tire in the axial direction, in the direction of the circumferential reinforcing element 7. This folding makes it possible to bring the said final end 8 close to the reinforcing element 7. Thus, at the level of the flanks 6, the carcass ply 2 comprises a reversal 12, and three adjacent portions consisting of a central portion 10 and two axially outer 9 and axially inner 11 side portions. [0038] In order to define the location of the various essential points, represented on the surface of the sidewall, these are projected onto a axial axis YY 'parallel to the radial direction ZZ' and tangential to the radial axis passing through the end of the nominal flange size E. [0039] It is recalled that the nominal flange size is the roll thickness of a tire mounted on a rim and inflated; the strand size being the distance between the two points located axially the outermost of the tire mounted on the rim and inflated. The top C of rim hook is projected on YY 'at a point C'. The point D, disposed on the surface of the sidewall, is projected onto YY 'at a point D'. The point S, corresponding to the axially outermost end of the crown reinforcement S, is projected onto YY 'at a point S'. The projection at A 'of the point A corresponds to half the length which extends from the point E to the point C'. The point A 'is the location radially as inner as possible of the radially upper end 12a of the upturn 12. According to the invention, the radially upper end 12a of the upturn 12 can not be disposed at a point radially inside the point A '. The point D 'is the radially outermost point possible for positioning the radially upper end 12a of the upturn 12. The location P10-3062 of this point D' may vary between the point A 'and the point S' . D 'may be the same as A' or S '. The bridge D is disposed at approximately 15% of the length between E and S 'starting from the point S', or at approximately 85% of the same length starting from the point E. [0045] Thus the radially upper end 12a of 12 may be disposed on the surface of the side between a point A and a point D, or between the projections of these same points A 'and D', knowing that the position of D 'may vary between the location of the points A 'and S'. In the representation according to Figure 1, the point A 'is disposed midway between the length between C' and E, 18mm. Point D 'is arranged at 36mm from point E for a tire of size 205/55 R 16 mounted on a rim of dimension 6.5 J 16. According to the representation of FIG. 1, the three adjacent parts 9, 10 and 11 of the overturning of the carcass ply 2 are folded back on itself so that the central portion 10 is adjacent to the side portions 9 and 11. An elastomeric decoupling composition 14 is disposed between the side portion 11 and the wall of the sidewall 2. This 14 is present up to a point F, located on the sidewall, and a distance equal to 17mm from the upper portion 12a of said upturn 12, to the inner portion of the radial direction. This composition 14 may also be present over a length equal to 60mm from the upper part 12a of the upward movement towards the upper part of the radial direction. This composition 14 can extend to a position axially inside the point S. The secant modulus of this composition 14 is between 2 and 57MPa. The presence of such an elastomeric composition makes it possible to precisely adjust the behavior and the endurance of the tire. In this particular embodiment, the reinforcements (not shown) of the carcass ply 2 have an angle equal to 75 ° with respect to the circumferential direction between the points A 'and D, which makes it possible to maintain a drifting thrust. correct. These same reinforcements have an angle equal to 85 ° with respect to the circumferential direction, between the points D 'and S', which makes it possible to maintain a good rolling resistance, and an angle equal to 90.degree. relative to the circumferential direction, in the region radially internal to the crown reinforcement 3. [0051] In FIG. 3, it can be seen that the end 8 of the carcass ply 2 is also folded twice in the identical direction to that of FIG. 1. The representation of this embodiment differs from that of FIG. 1 in that the decoupling composition 14 is furthermore present outside the most axially outer portion 9 of the upturn 12 until at a point G, located on the radially inner carcass ply of the end 12a, and 17 mm apart from said upper portion 12a of the upturn 12 towards the inner part in the radial direction. According to the invention, the absolute value of the angle of each of the three parts of the carcass ply is identical; only changes the sign of the angle of the axially outer portion 9 relative to the central portion 10 and the axially inner portion 11. In the embodiment of Figures 2 and 3, the reinforcements (not shown) of the carcass ply 2 have angles, with respect to the circumferential direction, identical to the embodiment of FIG. 1. EXAMPLE 1 Drift stiffness [0054] Drift rigidity measurements are obtained with a machine equipped with a treadmill and a device for measuring the transverse forces applied to the tire, as a function of the load. These measurements are carried out on a reference tire 205/55 R 16 mounted on a rim 6.5 J 16, inflated to a pressure of 2.5 bars, and subjected to a load P10-3062 of 483 daN. The tire is subjected to a speed of 80km / h with a drift angle of +/- 1 degree. The measurements are collated in Table I below. Pneumatic Control Tire According to the Invention Drifting Rigidity 100 As shown in the table, the tire according to the invention improves the drift rigidity by 6%. Example 2: Mass of the tire [0058] A mass measurement of the tire according to the invention in comparison with a control tire, for a reference of 205/55 R 16 shows a decrease of the total mass of the tire by 3%.
