专利说明:
[0001] The invention relates to an adapter for a wheel assembly formed mainly of a tire and a rim, and a wheel assembly comprising said adapter. The adapter and the roller assembly of the invention are preferably used in the field of tires for light vehicles, such as tourism and pickup truck, but still for heavy goods vehicles, for civil and agricultural tires. The definitions used in the present invention are described below: - "axial direction": direction parallel to the axis of rotation of the tire, - "radial direction": direction intersecting the axis of rotation of the tire and perpendicular to it, - "radially inside": means the radial distance measured from the axis of rotation of the tire is closer to the axis of rotation, - "radially outward" means radial distance measured from the axis of rotation of the tire is farther from the axis of rotation - "circumferential direction": direction perpendicular to a radius and lying in a plane perpendicular to the axis of rotation of the tire, - "radial section ": Section along a plane that contains the axis of rotation of the tire, -" equatorial plane ": plane perpendicular to the axis of rotation and which passes through the middle of the tread, -" assembled assembly ": ens emble comprising a tire, a steel or aluminum rim and the adapter according to the invention. P10-3211 [0004] In the application W002 / 068223, it is already known to insert between the rim and the beads of a tire a flexible shell of polymer material intended to ensure the junction between each bead of the tire and the seats of the tire. the rim with metal hooks arranged at each end of the ferrule. Due to its elastic deformability in the radial direction in the central part, the ferrule thus maintains, after inflation, a maximum pressure between the rim and the ferrule. However, one of the difficulties in the design of tires to be mounted on rigid rim is to make them insensitive to shocks, such as potholes. But if such a ferrule allows the wheel assembly to allow deformation in the radial direction, it was not designed to provide the overall flexibility sufficient in the axial direction to guarantee protection sufficient during shocks against a sidewalk or in holes in the roadway. At least the inventors wanted to reconstruct in another way, a classic rim so perfectly rigid without any contribution to a vertical suspension or flexibility. Other known solutions consist in reinforcing the carcass ply of the tire to ensure better protection of the tire against shocks. But such solutions do not allow to properly reduce the intensity of the mechanical forces supported by the vehicle during shocks on the sidewalk, let alone reduce the negative consequences on the tires. Also it remains necessary to transform the ferrule disclosed in W002 / 068223 in order to confer in addition an ability to vertical flexibility thus minimizing the partial damage, if not total, its internal structure, while maintaining a high level tire performance of the tire, especially its ability to develop significant drift. In addition, at least, in the event of damage due to an abnormally severe P10-3211 use of the tire, it is a matter of securing the vehicle by moving it a short distance following a destructive shock of the entire mounted. The invention therefore relates to an adapter for a wheel assembly having an axis of rotation comprising a tire having two beads, a rim having a rim groove disposed between two rim seats each having an axially outer end, said rim having a total width W between each axially outer end of said two rim seats, said adapter providing the junction between each bead and each seat of j ante, said adapter having: two axially outer ends each comprising an adapter seat and a front face; adapter support substantially comprised in a plane perpendicular to the axis of rotation, a body connecting said two outer axial ends so as to form a unitary piece and comprising at least one main reinforcing armature said adapter having a total axial width L included between each adapter seat, and - a face intended for be in contact with each rim seat and the rim groove, and disposed radially inside. The adapter is characterized in that the ratio W / L is greater than or equal to and less than or equal to 60% and in that said body comprises a locking element 20 for wedging said adapter in the throat of ante. Preferably the ratio W / L is greater than or equal to 25 and less than or equal to 50. [0013] The adapter according to the invention has the advantage of being of simple constitution and of using a conventional assembly. and already known from a tire on a rim for mounting the tire on the adapter in comparison with the shell of the document W002 / 068223 whose mounting steps are different and which use in particular P10-3211 a depression. This adapter also has the advantage of being non-removable unlike the device of the document W002 / 068223 which is only removable and which excludes the use of a complementary fastening means, such as a hoop. In addition, unlike the ferrule disclosed in W002 / 068223, a connection between the adapter according to the invention and the rim groove must always remain during the various stages of assembly. According to the document W002 / 068223, during assembly, the tire is, initially, disposed on the shell, then this assembly is depressed, thanks to the elasticity of the shell, before being disposed on the rim by axial sliding, and finally put under its nominal pressure. The depression during assembly leads to the non-contact of the ferrule and the rim. Therefore, to allow the correct maintenance of the tire on the rim after assembly, the rim must be as wide as possible so that after inflation, maximum effort can be exerted between the tire and the ferrule . The total width W of the rim must be less than the total width L of the adapter so as to ensure that the adapter has sufficient elasticity that can properly absorb the transfer of mechanical forces inherent in a shock. Such elasticity can not be obtained when the width of the rim is too great. The ratio W / L as defined in the adapter according to the invention thus ensures a mounted and inflated assembly, on the one hand, a permanent and sufficient mechanical connection between the tire and the adapter, and on the other hand, a correct absorption of the mechanical forces inherent in a shock. Another object of the invention is a rolling assembly consisting of a tire comprising two beads, a rim. This assembly is characterized in that it comprises an adapter as defined above, the adapter ensuring the junction between each bead of the tire and each seat j ante. P10-3211 [0018] Preferably, each outer axial end comprises an outer reinforcing element chosen from a metal (steel), nylon, PET, aramid. It may comprise a matrix of resin and / or reinforcing fibers, such as rayon, aramid, PET, nylon, fiberglass, carbon fiber, basalt fiber, poly (ethylene2,6 naphthalate) (PEN), polyvinyl alcohol ( PVA). The locking element may have a total axial length greater than or equal to 10% and less than or equal to 80%, and preferably greater than or equal to 30% and less than or equal to 50% of the total width W of said rim. This locking element is preferably present in the middle part of the adapter, the latter being intended to be inserted into the corresponding rim groove of the rim. The locking element may consist of one or more parts connected to each other or not. The locking element may also be present near one of the axially outer ends or on any location on the body disposed between the middle position of the adapter and one of the axially outer ends. The rim groove may also be arranged offset from the median of the rim. The rim would then have two rim seats of different lengths. Thus the locking element is inserted into the rim groove. The groove can then be arranged on any possible location on one of the two rim seats. The locking element preferably comprises a reinforcement which has an extension module greater than 4GPa, and preferably greater than 12GPa. This reinforcement may be selected from metal (steel), nylon, polyethylene terephthalate (PET), aramid. The blocking member may comprise a resin matrix and / or reinforcing fibers such as rayon, aramid, PET, nylon, fiberglass, carbon fiber, basalt fiber, poly (2,6-ethylene naphthalate (PEN), polyvinyl alcohol (PVA), polyketones P10-3211 [0024] The blocking element may be arranged at a length "1" situated between a median axis YY passing through the center of said blocking element and one of the support faces of said adapter [0025] This length "1" is between a minimum length and a maximum length defined by the following mathematical formulas: lmini = 0.1 (W + W / 2 + L) and lmaxi = L - 0,1 (W + W / 2 + L) In the case of use for a passenger vehicle, the rim seat will have a minimum length of 5mm, with lmini = 5 + 0.10W / 2 + 0.1L and 1maxi = L - (5 + 0.1W / 2 + 0.1L) The body of the adapter may comprise at least one protrusion. either on one axially upper end or on both. The projection is preferably made of an elastomer conventionally used in the field of the tire. The position of the projection on the adapter according to the invention may advantageously resume the parametric conditions defined by ETRTO (the European Tire and Rim Technical Organization). Thus the distance "d" between the center of the projection and the support face of the adapter will be a function of its total axial width L of the adapter. The table below gives some correspondence between the values of L and "d". Axial width L (inches) "d" minimum (mm) 3 13 P10-3211 Between 3.5 and 4 16> 4.5 21 [0029] The width "A" of rim seat is greater than or equal to 10% of the width W of the rim. The width "B" between the bearing face of an axially outer end of the adapter and the outer axial end of the rim seat closest to said bearing face is greater than or equal to 10% the total width L of the adapter, and preferably greater than or equal to 15%. For the wheel of a passenger vehicle this width "B" is greater than or equal to 21mm. The body of the adapter according to the invention is preferably made of a main reinforcement armature formed of at least one sheet of metal (steel), textile (rayon), aramid, PET, nylon cables. , fiberglass, carbon fiber, basalt fiber, poly (ethylene-2,6-naphthalate) (PEN), polyvinyl alcohol (PVA), polyketones parallel to each other in the sheet and radial. The ply is anchored in each axially outer end to each outer reinforcing member, such as a rod to form a flip. When the body comprises several layers of reinforcements, the latter have an angle of between 90 ° and 35 ° relative to the circumferential direction. When the body comprises only a single ply of reinforcements, it will be oriented between 60 ° and 90 °, and more preferably at 90 °, with respect to the circumferential direction. The main reinforcing armature of said body may have an expansion module greater than or equal to 4GPa. The sheets preferably comprise the elastomer constituents conventionally used in the tire field, such as the crosslinkable rubbers by chemical vulcanization reactions by sulfur bridges, by P10-3211 carbon-carbon bonds created by the action of peroxides or ionizing radiation, by other chains of atoms specific to the molecule of the elastomer, secondly, the thermoplastic elastomers (TPE) where the elastically deformable part form a network between "hard" regions little deformable which the cohesion is the result of physical bonds (crystallites or amorphous regions above their glass transition temperature), then the non-thermoplastic elastomers and finally the thermosetting resins. The body of the adapter may comprise a hoop disposed on at least a portion of its radially outer surface and / or at least a radially inner portion of the reinforcing armature. The hoop used according to the invention is chosen from the materials conventionally used in this function and in the field of the tire, and having an expansion module greater than or equal to 4GPa, or even greater than or equal to 12GPa. This hoop may be secured or not to the adapter. If it is not attached to the adapter, it can be put in place after mounting the adapter on the rim. The hoop can be glued cold or hot on the adapter. The hoop can still be fixed by any mechanical means, such as tightening, screwing. In the case where the adapter is fixed before being disposed on the rim, then the assembly between the rim and the adapter is made in force. The adapter is therefore rendered indissociable from the rim, and therefore not removable. The adapter can be cold or hot glued on the rim after a possible prior treatment of the metal constituting the rim. When the adapter is glued hot or cold on the rim, the adapter is not removable. In other cases, it may be considered removable. The invention will now be described with the aid of the appended examples and figures which are only given by way of illustration, and in which: FIG. 1 represents a schematic sectional view of a mode embodiment of the adapter according to the invention, - Figure 2 shows a schematic sectional view of an embodiment of the adapter according to the invention mounted on a rim, and - Figure 3 shows a schematic view in section of another embodiment of the adapter according to the invention, and - Figure 4 shows a schematic sectional view of a roller assembly comprising the adapter according to the invention, a tire and a rim according to a first embodiment, - Figure 5 shows a schematic sectional view of a roller assembly comprising the adapter according to the invention, a tire and a rim according to a second embodiment, - Figure 6 shows a schematic sectional view. of an assembly Roller comprising the adapter according to the invention, a tire and a rim according to a third embodiment. As shown in Figure 1, the general reference adapter 1, substantially of linear shape, comprises two axially opposite outer ends 2 each comprising an adapter seat 3 and a corresponding adapter support face 4 substantially included in a plane perpendicular to the axis of rotation of a tire. A body 5 connects the two ends 2 so as to form a unitary piece. The body comprises at least one reinforcing reinforcement 6 consisting of two plies comprising textile reinforcements. The two plies form an angle of 45 ° with the circumferential direction. The adapter has a total axial width L equal to 190.5mm measured between each support surface 4. P10-3211 A face 16 may be delimited by surface markers and located radially inside the adapter 1, is intended to be in contact with a rim groove 13 and the rim seats 12 (Figure 2). The body 5 comprises in its middle part (represented by an axis 7) a locking element 8 having a total axial length equal to 25% of the width L for a passenger wheel width 7.5 inches, or 190.5 mm. The locking element 8 is made of rubber which has an extension module equal to 50GPa. According to this embodiment, the adapter comprises a hoop 9 disposed on at least a portion of the radially outer surface of the body 5. The hoop is made of materials conventionally used in textile or metal-based tire. The radially outer ends 2 each comprise an outer reinforcing element 10, also called a bead wire, made of a glass-resin composite material. As shown in Figure 2, the adapter 1 is disposed on a rim 11 partially shown. This rim comprises two rim seats 12 separated by a rim groove 13. In the embodiment of FIG. 3, the adapter comprises, in addition to the elements mentioned above, two projections 14 each disposed on the body 5, and whose centers are spaced apart by a distance "d" of at least 21 mm from the end of the bearing surface 4. These two projections 14 are made of elastomeric rubber, optionally reinforced with cables arranged mainly in the circumferential direction. Figure 4 shows a mounted assembly comprising a rim 11 of width W on which is inserted the adapter 1 and on which is inserted a conventional tire 17 through its beads 18. P10-3211 [0050] The assembly this assembly is carried out in a conventional manner and known by forcing the adapter on the rim so that the locking element 8 is inserted into the groove 13. The beads 18 of the tire 17 are then arranged each on a seat 12 of the adapter 1. The assembled assembly is then put under its nominal pressure. In Figure 4, the locking member 8 is disposed in the middle part of the rim. As shown in Figure 5, the locking element 8 is disposed offset with respect to the central axis XX 'of the adapter but centrally relative to the central axis ZZ' of the rim . It is arranged at a distance "1" greater than or equal to (W / 2 + 21) mm for a wheel of width 7.5 inches, or 190.5mm. The length "1" located between the center of the rim groove and the axially outer end of the adapter respects the physical constraints A> 5mm and B> 21mm, where A is the width of a rim seat and B the distance between the bearing face 4 of an axially outer end of the adapter and an axial end 11A of a rim seat. As shown in FIG. 6, the blocking element 8 is arranged offset with respect to the median axis ZZ "of the rim and with respect to the median axis XX 'of the adapter. figure, it is arranged at a distance "1" in mm from the center of the axially outer end of the vehicle, where 1 = L - W + 5 + W / 200 - 21 For a vehicle wheel for reference tourism 7 , 5 J 17, West equal to 50 mm, L to 190.5 mm and "1" to 56 mm The following examples show the results obtained with the adapter according to the invention. Sidewalk tests P10-3211 This test consists in mounting a set mounted on a sidewalk at an angle of attack of 30 ° C. The choice of this angle is based on the fact that it constitutes a very penalizing stress for a tire. The test is carried out with two different sidewalk heights (90mm and 110mm). [0002] The test proceeds as follows. Several passages of the wheel are made at different speeds until the tire is punctured. The starting speed is 20km / h, then we increment the speed of 5km / h at each new passage. A conventional assembly without an adapter (indicator 1) is compared to an assembly equipped with an adapter according to the document W000 / 78565 (indicator 2), and to an assembly provided with an adapter according to the invention (invention). These sets are all of size 205 / 55R16 including a 6.5J16 rim. The results are collated in the following Table I and are given in percent: Control 1 Control 2 Invention Percentage of the 100> 150> 150 puncture speed compared to the control - Sidewalk height 90mm Level of effort 100 50 40 Vertical reach ( Fz) measured at the puncture speed Condition of the assembly - tire puncture - Tire and wheel intact Tire, adapter and shock mounted - including wheel - Adapter plastically deformed wheel marks Table I P10-3211 The results above 100 show improved behavior in the event of a lateral shock.
