    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 following are the definitions used in the present invention: - "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, - "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 which 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 [0003] In the application W000 / 78565 it is already known to insert, between the rim and the beads of a tire, an elastic adapter. This adapter is elastically deformable, in the radial and axial directions. Such an adapter makes it possible to dissociate the part of the rolling assembly that can be considered as actually working as a tire, from the part of the rolling assembly that can be considered as working as a jutte. [0004] But if such an assembly also makes it possible to perform the functions of a conventional tire, and in particular a tire drift thrust response according to the application of a drift angle to the tire, which thus allows the assembly to sufficient flexibility to prevent any surface degradation or depth, it does not quite ensure sufficient deformability of the tire when P10-3199 shocks on sidewalks or holes in the roadway, such as potholes . Indeed, the assembly mounted with the adapter of the state of the art does not obtain a local deformation in the area of the contact area.
    [0002] The teaching of this document also has the disadvantage of not allowing easy to obtain embodiments of the adapter having a large capacity to absorb large deformations when passing in potholes without residual plastic deformation. No suggestion is given in this document on architectural adaptations that would result in a deformation of the outer reinforcement located in the area of the contact area leading to a reduced against-arrow and thus making the assembled assembly less intrusive vis-à-vis the vehicle. Also the need remains to have a new adapter that provides better protection of the tire during impacts on the tire due to use on roads in poor condition, thus minimizing the damage partial or total , of its internal structure, while maintaining a high level tire handling performance, particularly its ability to develop significant drift. In addition, at least, in case of damage due to abnormally severe use, it is to secure the vehicle by moving a short distance following a destructive shock for the whole. The invention therefore relates to an adapter for a roller assembly having an axis of rotation and comprising: - a tire having two beads, and - a rim, said adapter ensuring the junction between one of the beads and the rim, said rim having two rim seats, P10-3199 said adapter having: - an axially inner end to be mounted on the rim seat and comprising an inner reinforcing member, - an axially outer end comprising an outer reinforcing member, a body connecting said outer end with said inner end so as to form a unitary piece and comprising at least one main reinforcing armature ensuring the connection between said outer reinforcement and said inner reinforcement; a substantially cylindrical adapter seat intended to receive one of said beads, said seat being located at the axially outer end of said horn ps, - an adapter bearing face substantially in a plane perpendicular to the axis of rotation, said bearing face being located on the axially inner face of the axially outer end. The adapter is characterized in that the annular seat reinforcement has a compression module greater than or equal to 1GPa. The adapter of the invention has the advantage of being simple constitution and assembly. The adapter according to the invention also allows, by increasing the clamping under the beads of the tire, to prevent its rotation on the adapter in strong lateral stress. Finally, the adapter according to the invention has the advantage of significantly reducing the level of mechanical forces to the chassis during a shock, and thus to lighten the vehicle body. P10-3199 Another object of the invention is a rolling assembly consisting of a tire comprising two beads and a rim. This assembly is characterized in that it comprises at least one adapter according to one of the preceding claims, the adapter ensuring the junction between a bead of the tire and the rim. Preferably, the reinforcing element of the axially outer end is entirely located axially outside the bearing face, and the body comprises facing the adapter seat an annular seat reinforcement. Preferably, the annular seat reinforcement has a compression modulus greater than or equal to 4GPa, and more preferably greater than or equal to 10GPa. The annular reinforcement may consist of a core surrounded by an elastomer, or a succession of layers of elastomeric compounds and metal and / or textile reinforcements arranged in any possible combination. The core may comprise at least one element selected from a metal, a composite material, a thermoplastic and their mixture. The composite material could be made from glass fibers embedded in a resin matrix. Among the elastomers that may be used, the cross-linkable rubbers are firstly listed by vulcanization chemical reactions by sulfur bridges, by carbon-carbon bonds created by the action of peroxides or ionizing radiation, by other chains of atoms specific to the molecule of the elastomer, in the second place, the thermoplastic elastomers (TPE) where the elastically deformable part form a network between "hard" regions of little deformability whose cohesion is the result of bonds physical (crystallites or amorphous regions above their glass transition temperature), then non-thermoplastic elastomers and finally thermosetting resins. The annular seat reinforcement may consist of at least two layers of different constituents successively arranged alternately. By alternating arrangement, it defines a successive arrangement of a first and a second layer, several times. P10-3199 The annular seat reinforcement may have a total axial length greater than or equal to 30% of the width of the bead of the tire, and less than 150% of this same width, and more preferably between 40 and 110% the width of the bead of the tire. The annular seat reinforcement may have an average radial thickness greater than or equal to 0.3 mm and less than or equal to 20 mm depending on the size and use of the tire. Thus, for a passenger tire, the thickness is preferably between 0.5 and 10 mm. The annular seat reinforcement preferably comprises at least one element selected from a metal, a composite material, a thermoplastic, and their mixture. This core or multilayer is preferably between two layers of a matrix comprising optionally an elastomer as mentioned above, a resin or mixtures thereof. The annular seat reinforcement preferably consists of a stack of different layers of elastomeric compounds of identical or different chemical nature. When it is in the form of a stack of layers, the reinforcement preferably has an axial length greater than 5 mm and less than 25 mm, and a radial thickness greater than or equal to 0.1 mm and less than or equal to 4 mm. Each unit element constituting the stack of the reinforcement may have an axial width greater than 1 mm and less than 25 mm, and a radial thickness, identical or different, greater than or equal to 0, 1 mm and less than or equal to 2 mm. The annular seat reinforcement may also be in the form of a stack of single son between a layer of a matrix optionally comprising an elastomer, a thermoplastic compound, a resin or mixtures thereof. The unitary yarns can be conventionally used yarns, such as textiles (polyester, nylon, PET, aramid, rayon, natural fibers (cotton, linen hemp)), metal, composites (carbon, glass-resin) or mixtures of these constituents. . P10-3199 [0024] The annular seat reinforcement may also be in the form of one or more plies, the reinforcements of which are arranged at an angle of between 0 and 90 ° with the circumferential direction of the tire. Preferably, the annular reinforcement may be arranged radially on the outside or radially inside the body of the adapter, on either side of said body, or even between the layers of elements of reinforcement of the body of the adapter. The outer reinforcing element may be made of 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 main reinforcing armature of said body may have a module greater than or equal to 4GPa; it can be made of metal (steel) in textile cable (rayon, aramid, PET, nylon, fiberglass, carbon fiber, basalt fiber, poly (ethylene2,6 naphthalate) (PEN), polyvinyl alcohol (PVA) [0028] Preferably, the adapter may be arranged on one side of the rim, and preferably on the outside of the vehicle, in which case the rim has an asymmetric geometric shape so as to adapt to the presence of the adapter present on one side When the assembled assembly comprises two adapters, the latter may be symmetrical or unsymmetrical The concept of symmetry or dissymmetry of the adapter is defined by the axial length of the body Two adapters are asymmetrical when the body of one of them has an axial length greater than that of the other. [0030] Preferably, the rolling assembly comprises a first and a second adapter. each having a body of length same or different P10-3199 The invention will now be described with the aid of the following examples and figures, which are given by way of illustration only and in which: FIG. schematically the adapter according to the prior art, - Figure 2 shows schematically and in radial section a tire mounted on two adapters according to the invention, themselves embedded on the rim removably; and FIG. 3 represents a schematic view in radial section of an unassembled adapter according to the invention. FIG. 1, which represents an adapter according to the prior art, comprises a tire P (partially shown), an adapter A and a rim J. [0033] The design tire, which is in itself unchanged in the invention, is formed of a tread reinforced by a crown reinforcement joined to two beads B on either side of an equatorial plane XX 'through two sidewalls 1. A carcass reinforcement 2 mainly reinforcing the sidewalls 1 is anchored in each bead B to at least one rod, here of the "braided" type 3 to form reversals 4, separated from the main carcass reinforcement portion by quasi-triangular shaped profiles 5. [0034] It is It is important to note that the invention can be implemented with many types of tires, whether radial or diagonal carcass, or even with self-bearing sidewall type tires. The rim J comprises a groove 6, said assembly, and bringing together on either side of the equatorial plane, two rim seats 7 axially extended by rim hooks 8 whose radially outer edges are curved. The adapter A mainly comprises an axially outer end 9, an axially inner end 10 and a body 11 connecting said end 9 to said end 10. P10-3199 [0037] The axially outer end 9 comprises a reinforcing element outside 20 consisting of a first portion 20a connected to a second portion 20b and forming an angle substantially perpendicular to each other. During the mounting of the tire, the bead seat of the bead B fits into the space created by this external reinforcing member 20. [0038] FIG. 2 represents a mounted assembly comprising two adapters A according to the invention, connecting the B beads of the tire P to the two rim hooks 8 of the rim J. The adapters of this Figure 2 are removable with respect to the rim J and B beads of the tire. The adapter A disposed at each bead B of the tire may be symmetrical or unsymmetrical. By symmetry, it is defined that the total length of the body 11 is identical on both adapters. When the assembly (tire, rim and adapter) is mounted, the beads B of the tire are arranged on the adapter seat 14 and placed in axial abutment against a bearing surface 21. [0040] FIG. according to the invention, not mounted on rim. This adapter comprises, on the one hand, an axially outer end 9 with an outer reinforcement 15, of substantially spherical geometric shape, in section, made of composite material such as glass-resin, on the other hand, an axially inner end 10 with a metal reinforcement 16, and finally a body 11 consisting of two plies 17 comprising textile cables. The cables of each sheet are parallel to each other. Said plies 17 are, on the one hand, axially contiguous inside and radially on the outside of the walls of the reinforcement 15, and on the other hand, anchored in the end 10 to the metal reinforcement 16, such as a rod forming a flip at each end. The body 11 comprises a substantially cylindrical adapter seat 18 for receiving a bead of the tire (see Figure 2) disposed at the axially outer end of the body 11. [0042] The body 11 also comprises a face of adapter support 21 substantially in a plane perpendicular to the axis of rotation, located on the P10-3199 axially inner face of the axially outer end, and for holding in place the bead in its housing. This adapter seat 18 comprises an annular seat reinforcement 19 having a compression modulus equal to 100GPa. According to the representation of this Figure 3, the entire reinforcement 19 is disposed on the radially outer surface of the surface of the body 11. Unlike the known device (Figure 1), the annular seat reinforcement 19 is not secured. external reinforcement 15. These two reinforcements 19, 15 are completely independent of one another. The reinforcement 19 consists of a trilayer comprising metal reinforcements in the form of son, alternated with a rubber-resin elastomer. The reinforcement 19 has a radial thickness of about 1.5 mm and an axial length of about 15 mm. The elastomer layer of the reinforcement 19 has a radial thickness of about 0.3 mm and an axial length of about 15 mm. An elastomeric layer 20 covers all the elements constituting the adapter, namely the reinforcement 15, the reinforcement 16, the body 11 and the radially outer surface of the reinforcement 19. The following examples show the results obtained with the adapter according to the invention. Example: Tests on sidewalk This test is to mount a set mounted on a sidewalk at an angle of attack of 30 °. 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).
    [0003] The test proceeds as follows. Several passages of the wheel are made at different speeds until the tire is punctured. The speed of P10-3199 departure 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 - Pneumatic tire and wheel intact Tire, adapter and shock mounted - including wheel - Adapter plastically deformed wheel intact marks Table I Results greater than 100 show a improved behavior in the event of a side impact. The test carried out on the sidewalk height of 90 mm results in the puncture of the control tire at a speed of 30 km / h, whereas the assembly according to the invention undergoes no damage at this same speed, even at a speed of 50 km. / h. P10-3199 The test performed on the curb height of 110mm results in the puncture of the control tire at a speed of 20km / h, while the assembly according to the invention undergoes no damage at this same speed, or even speed of 50km / h.
