    [0001] FIELD OF THE INVENTION [0001] The present invention relates to a tire provided with a directional tread adapted for winter weather conditions involving, for example, covered roads. ice and / or snow, the tread being provided with a plurality of curved blocks aligned along the tread.
    [0002] STATE OF THE PRIOR ART (0002) US4057089 discloses a tire comprising a tread provided with a plurality of blocks, each of these blocks being arranged in the shape of a curve and extending from the center of the tread towards a tread. Some blocks are arranged in the form of a parabola curve of the second degree.The blocks are connected to a central strip.The blocks being relatively wide, the rigidity of these same blocks is therefore important, resulting in rapid wear of The tread W02013 / 048682 generally relates to tires whose treads have a configuration and / or properties adapted to snowy ground conditions, but also for a dry ground. discloses a tire having a tread with a high density of lamellae in the contact zone, a reliable density of lateral grooves and a minimum value of ra tio longitudinal contact area. These characteristics give the tire a good compromise between the braking characteristics on snowy ground and on dry ground. Nevertheless, in a perspective of continuous improvement of tire performance levels, designers are looking for even more efficient solutions, especially with regard to performances on snow-covered ground. P10-3543en 3033144 2 [0004] To overcome these disadvantages, the invention provides various technical means. SUMMARY OF THE INVENTION [0005] Firstly, a first object of the invention is to provide a tread for a tire which makes it possible to improve the durability of a tread provided with blocks configured according to curved profiles. . Another object of the invention is to provide a tread making it possible to obtain an excellent compromise of adhesion on snow-covered ground / wet ground while preserving the performances on dry ground. [0007] To this end, the invention provides a tire comprising a directional rolling strip, said tread comprising two edges and a center, this tread comprising a plurality of blocks, each block extending continuously. according to an overall curvature C of one of the edges towards the center of said tread forming a central end of block, each block having a width WB and a length LB, this width increasing from the central end of the block towards of the edge, all or part of the blocks of the tread comprising a median incision of length S, said median incision extending along a curvature C 'substantially identical to the curvature C of the block, according to the invention, the length S of the median incision is determined so that 0.5.LB S 0.8 L.LB and all or part of the tread blocks comprises a lateral incision arranged in the extension of the incision m diane and decoupled from said midline incision. This lateral incision allows an increase in the number of ridges in the shoulder area and consequently improves braking and traction on snowy road. The decoupling between the lateral incision and the median incision makes it possible to locally increase the rigidity of the block which comprises these incisions. Advantageously, the median incision extends from the central end of the block This arrangement improves the grip on snow-covered ground more specifically at the central zone of the strip. [0010] Also advantageously, the lateral incision widens from a certain depth in the tread, forming an incision widening, said incision widening opening onto the shoulder of the tire. Beyond the edge of the tread, this widening of the incision makes it possible to prolong the favorable characteristics of adhesion on snowy ground despite the wear of the blocks, up to, for example, about 3 mm in height. Furthermore, the drop-shaped profile allows water to be stored and promotes wet performance. [0012] Advantageously, the curvature C 'of the median incision is determined from so that the report of pr ojections Sx / Sy corresponds to 0.5Ex / Sy 5 1.25, with Sx denoting the projection of the length S of the incision along a circumferential axis X of the tread and Sy denoting the projection of this length S along a transverse axis Y of the tread. Such an arrangement makes it possible to obtain an advantageous compromise between the grip characteristics on snow-covered ground / wet ground without loss of performance for braking on dry ground. This gain is due to the coupled effect of the ridges created by the incisions and their orientations which have a frictional effect on the snow and thus improve the adhesion. The presence of the incision as well as the orientation of the latter make it possible to improve the grip on snowy ground because of the edges. In addition, the incision interruption zone makes it possible to increase the rigidity along the X axis and to improve braking on dry ground. [0014] This tire is advantageously intended for all-season use. According to an advantageous embodiment, all or part of the blocks of the tread comprise a generally circumferential incision arranged at one end of the median incision opposite the central end of the block, said incision globally circumferential extending from one edge to the other of the block. This circumferential incision promotes transverse flattening of the tire. The rigidity in the shoulder area is however retained to allow a good cornering behavior. According to an advantageous embodiment, the circumferential incision is in the form of a V whose point has an angle α of between 1000 and 170 ° and preferably between 150 ° and 170 °. In a variant, the circumferential incision is in the global form of "S". In another variation, this incision may comprise several small segments while maintaining a generally circumferential orientation. Advantageously, the blocks comprise three zones: a central zone with an angle 31 with respect to the transverse direction (Y) such that 20 35S131565 °, an edge zone with an angle 133 with respect to the direction cross-section (Y) such as 0 ° 5133510 °, and an intermediate zone between the central zone and the edge zone with an angle 132 for continuity between the three zones. According to an advantageous embodiment, at least a portion of the median incisions comprise an incision chamfer. The incision chamfer is advantageously located in the intermediate zone of the block. Alternatively, it extends to the generally circumferential incision. This arrangement improves the braking on dry ground. According to another advantageous embodiment, at least part of the blocks is arranged with a block chamfer provided at the trailing edge of the intermediate zone and / or the edge zone. the central zone being devoid of chamfer. This arrangement also improves the braking on dry ground. Preferably these chamfers are at 45 °, with a section of between 1x1 mm and 2x2 mm. They can also be constituted by a radius (1 to 2 mm) connecting to the faces of the blocks. According to another advantageous embodiment, at least a part of the median incisions comprises stiffening means connecting, for each incision, the opposite faces of this incision. The stiffening means are particularly advantageous in the central zone, this zone having the largest angle relative to the transverse direction (Y). The stiffening means are preferably arranged in the incision at intervals of 5 to 20 mm. The height of stiffening means is preferably between 40 and 80% of the maximum height of the incisions. Thus, these stiffening means do not extend to the surface of the tread when the tire is new. [0025] Advantageously, in at least one incision, the spacing between the stiffening means is variable. [0026] Also advantageously, the stiffening means are integral with the tread. Also advantageously, the blocks consist of an elastomer composition based on a diene elastomer, a plasticizer system 30 and an inter-linkage system, in which the elastomer composition comprises a glass transition temperature of between - 40 ° C and -15 ° C and a shear modulus G * measured at 60 ° C between 0.5 MPa and 1.1 MPa. Such a composition allows use in winter conditions with very cold temperatures without degradation of performance. In addition, the applicants have found, surprisingly, that the tread according to the invention, with a general appearance of the blocks evoking a summer-type tire, has particularly advantageous behavioral characteristics on snow-covered ground and / or The limits of these performances are further favorably repelled with the use of the previously described compositions. [0030] In addition, advantageous performance gains are observed when the glass transition temperature of the elastomeric composition is between -20.degree. ° C. and -30 ° C. [0031] The shear modulus G * is preferably between 0.9 MPa and 1 MPa DESCRIPTION OF THE FIGURES [0032] All the details of embodiment are given in the description which follows. , supplemented by FIGS. 1 to 4, presented solely for purposes of non-limiting examples, and in which: FIG. 1 is a schematic representation of a ortion of a tread corresponding substantially to the contact area; - Figure 2 is a schematic representation of a block for a tread such as that of Figure 1; FIG. 3 shows an alternative embodiment of the block of FIG. 2; FIG. 4 is a partial schematic representation of an alternative embodiment of the tread of FIG. 1 with bridges arranged along the incisions. DETAILED DESCRIPTION OF THE INVENTION DEFINITIONS In this document, curvilinear length "L" or "S" means a length measured taking into account the curvature of the "L" element. or "S" measured. [0034] By "directional sculpture" is meant a tread band sculpture whose sculpting elements are specifically arranged to optimize the behavioral characteristics as a function of a predetermined direction of rotation. This direction of rotation is conventionally indicated by an arrow on the sidewall of the tire. In such an architecture, the edges of the carving elements which are towards the rolling direction are referred to as the "leading edge", while the edges of the carving elements which are opposite to the rolling direction are designated by the term "trailing edge". In addition, a "directional sculpture" is a sculpture involving a preferential direction of travel such that, when the tire is rotated in said preferred direction, this tire offers better ground adhesion properties than those offered when said tire is rotated in the other direction. A directional sculpture is, for example, a sculpture with generally V-shaped patterns. By "incision" is meant a slit or slit (between 0.1 and 2 mm) and elongated cut in a tape block. The term "median incision in the block" is understood to mean that this median incision separates this block into two generally identical block portions, the difference in area between these two block portions being less than 10%, by 30%. surface means that which may be in contact with the ground in the contact area P10-3543en 3033144 8 "Lateral incision" means an incision extending generally in the transverse direction Y, the angle formed by the direction of extension of this incision with the transverse direction Y being less than 15 degrees, in absolute value [0038] By "decoupled lateral incision of the median incision", it is meant that there is a zone of gum between the incision The length of this gum area is at least 2 mm. By "circumferential incision" is meant an incision extending generally in the circumferential direction X, the angle formed by the direction of extension of this incision with the circumferential direction X being less than or equal to 20 degrees. , in ultimate value. By "each block extending continuously from an edge 3 to the center 4" is meant that the block is not interrupted by separating grooves separating this block into different sub-blocks. Groove means a cutout whose material faces do not touch in the usual conditions of rolling. The width of a groove is greater than or equal to 2 mm.
    [0003] Thus, the fact that these blocks are not interrupted by separating grooves makes it possible to improve the evacuation of water from the center 4 to the edge 3, the presence of such separating grooves being able to disturb the flow of the flow of water. water to the outside of the tire. By "overall curvature C of the block" is meant that the block has a curved shape. This curvature can be constant or continuously variable. In another variant the curvature consists of a succession of segments. [0042] By "global curvature C" of the median incision "is meant that the medial incision 30 has a curved trace. This curvature can be constant or continuously variable. In another variant the curvature consists of a succession of segments. P10-3543en 3033144 9 "Tread" means the area of the tire of which at least a portion is subjected to contact with the ground and is worn by this contact with the ground.
    [0004] DESCRIPTION OF THE FIGURES [0044] FIG. 1 substantially illustrates the contact area of a tire tread 2. The contact area has a maximum width WA defined by the ETRTO standard and illustrated in FIG. 1. between the dotted lines delimited by the WA width. The standard ETRTO provides a width WA = (1.075-0.005ar) * S I where with "ar" the nominal aspect ratio and S the size of the theoretical flange on the measuring rim. The edges 3 of the tread are in correspondence with the dotted lines delimiting the width WA. According to the invention, the tread 2 comprises a plurality of blocks 5. Each of the blocks extends from an edge 3 of the tread towards the center axis 4 of the tread as follows. overall, a curvature C. The term "toward the center" means here that the block ends at the center, or just before the center or just after the center. The center 4 is defined by a line extending in the circumferential direction and dividing the tread into two halves. For large tire dimensions, a longitudinal groove can be added at this center 4. [0046] Each of the blocks is of length LB and of width WB, this width increasing from the central end of the block towards the edge 3. The blocks are advantageously configured in three zones, namely a central zone, an intermediate zone and an edge zone. The central zone forms an angle (31 with respect to the transverse direction (Y) of between 35 ° and 65 ° and more preferably of substantially 50 ° + -5 ° C. At the edge of the blocks, there is the edge zone with a angle 133 with respect to the transverse direction (Y) between 0 ° and 10 ° In order to ensure a continuous connection between these two zones, the intermediate zone is provided. connection between the central zone and the edge zone with an angle 132 allowing continuity between the three zones Due to this three-zone arrangement, the blocks comprise a curvature C, progressive from the edge 3 towards the center 4 For the shaping of this curvature, the sides of the blocks form, as the case may be, either a continuous curved line from the edges 3 towards the center 4, which may be variable curvature, or a plurality of angular segments, as represented. Figures 2 and 3. In the case where a block area is configured by a succession of segments, the angle 13 is the average angle. In the case where a block area is configured by a curvilinear segment, the angle 13 corresponds to the average of the angles along the curvature. [0047] At least a portion of the blocks 5 comprises a median incision 10 extending along the block following a curvature C 'similar to the curvature C of the block. This incision makes it possible to separate the block into two parts 8a and 8b, with preferentially substantially identical volumes. Alternatively, only a part of the blocks 5 comprises a median incision 10. The median incision 10 makes it possible to reduce the rigidity of the block 5 separating it into two half-blocks. The rigidity of each half-block is substantially identical, contributing to uniform wear of these two half-blocks. The median incision 10 has a curvilinear length S. This length S of the median incision is preferentially determined so that 0.5.L S 0,8 0.8.L. According to the invention, at least part of the blocks 5 comprises a generally circumferential incision 11 arranged at the end of the median incision 10. By "generally circumferential" is meant an arrangement such as the projection ratio Ry / Rx corresponds to 0 5 Ry / Rx E 0.6. This incision produces a decoupling effect favoring the flattening of the tire. [0050] The examples of FIGS. 1 and 2 illustrate generally V-shaped circumferential incisions 11 whose tip of the V forms an angle comprised between 1000 and 170 ° and preferably between 150 ° and 170 °. . According to the embodiments, the tip of the V may be oriented either towards the center of the tread, or towards the proximal edge of the tread. A V-shaped incision improves adhesion in the longitudinal and transverse directions. The embodiment of Figure 3 shows a block 5 whose generally circumferential incision 11 is shaped "S". The profile formed is sufficiently elongated for the incision to meet the criterion that the projection ratio Ry / Rx is between 0 and 0.6. Finally, the blocks 5 provide at least one lateral incision 12, arranged at the level of the block edge area. This incision is shifted transversely to the medial incision 10 and the circumferential incision 11. The offset 15 between this incision and the other incisions is preferably between 3 and 6 mm. This offset, by increasing the stiffness locally, contributes to improving the braking efficiency on dry ground. Preferably, this lateral incision 12 widens out from a certain depth of sculpture, forming an incision enlargement 13. This widening 13 incision opens on the shoulder of the tire and forms a teardrop-shaped profile. Advantageously, the incisions 10 and 12 are arranged at the level of the neutral fiber of the blocks, that is to say so as to separate the blocks into two parts of substantially identical volumes. The depth of the incisions is preferably between 85% and 105% of the depth of the grooves defining the blocks. FIG. 3 also shows an incision chamfer 14 provided at the middle incision 10. In the illustrated example, the incision chamfer 14 extends along the intermediate zone, then slightly beyond this zone on an adjoining portion of the edge zone, substantially to the incision 11 globally circumferential. A block chamfer 15 located at the trailing edge of the edge zone and the intermediate zone is also shown. The edge zone and the intermediate zone, because of their small inclination with respect to the transverse direction Y, are the most sensitive to the tilting phenomenon during strong braking stresses. edge of the trailing edge which, under certain conditions, penalizes the braking.The presence of chamfers previously described can mitigate or even eliminate this phenomenon. [15] The presence of chamfers on too many edges This has the effect of reducing the volume of material to be used and increasing the rate of surface notching, with a negative impact on the noise emitted by the tire.To avoid these drawbacks, the central zone, more inclined, is devoid of chamfers. This judicious distribution of the chamfers limits their use to the areas in which they are most effective. [0060] FIG. comprising stiffening means 16 such as bridges arranged at certain positions along the middle incision 10. These bridges can greatly reduce the retention of pebbles in the incisions. In addition, it has been found that a DP spacing between the bridges 16 lying between 15 mm and 20 mm makes it possible to optimize this non-retention effect, without affecting the efficiency of the lamellae on snowy ground. According to the embodiments envisaged, this type of arrangement makes it possible to provide incisions of a length of the order of 70 mm. The tread blocks consist of an elastomeric composition based on a diene elastomer, a plasticizer system and an inter-linkage system, in which the elastomeric composition has a temperature of between 10 and 20 mm. glass transition between -40 ° C and -15 ° C and a shear modulus G * measured at 60 ° C between 0.5 M Pa and 1.1 Pa. [0062] The diene elastomer is selected in the group comprising natural rubber, styrene-butadiene rubber, polyisoprene synthetic rubber, polybutadiene rubber and any combinations of these components. The plasticizer system comprises plasticizers selected from a plasticizing oil, a plasticizing resin or any combination thereof. The plasticizing resin is a polylimonene resin. The plasticizing oil is selected from a petroleum-based oil, a vegetable oil, or any combination thereof. [0064] The figures and their descriptions made above illustrate the invention rather than limiting it. In particular, the invention and its various variants have just been described in connection with a particular example comprising identical blocks on the entire surface of the tread. Nevertheless, it is obvious to a person skilled in the art that the invention may be extended to other embodiments in which, in variant, non-identical blocks are provided either along the circumferential alignment or both sides of the center line of the tread. It may also be provided that at least one of the ends of the median incisions 10 comprises a bridge in the central portion of the tread and / or between the medial incision and the circumferential incision. Reference signs in the claims are not limiting in nature. The verbs "understand" and "include" do not exclude the presence of elements other than those listed in the claims.
