    [0001] FIELD OF THE INVENTION [0001] The present invention relates to wheels intended to be equipped with tires, and more particularly the wheels of these wheels. BACKGROUND [0002] When a vehicle equipped with wheels provided with tires rolls on the roadway, the imperfect state thereof may have a negative effect on the comfort of the user of the vehicle, by increasing the noise that is exposed this user, and the integrity of the vehicle including tires. Indeed, they suffer first shocks from, for example, contact with a sidewalk or with a "pothole", that is to say a cavity in the pavement generated by a degradation of its coating. SUMMARY OF THE INVENTION [0003] One of the objectives of the present invention is to define a wheel rim intended to be equipped with a tire, making it possible to reduce the risk of damage to the tire resulting from shocks of the sidewalk or nest impact type. hen, and improve the comfort of the user of a vehicle whose wheels are equipped with such rims, by reducing the noise in the vehicle and reducing the inconvenience caused by crossing small irregularities of the road, as example of the manholes. This object is achieved by a vehicle rim, of revolution, for mounting a tire, comprising: an axially central portion comprising a disk; two lateral parts, at least one of the lateral parts (and preferably the two lateral parts) being distinct from the axially central part, each of the lateral parts being provided with a rim seat intended to receive a bead of a tire, the axially central part and the two lateral parts being made in a rigid matrix that can be reinforced by a reinforcing reinforcement; An intermediate part forming the only mechanical link between the axially central part and each distinct lateral part of the axially central part, this intermediate part being made in a flexible matrix reinforced by a reinforcing reinforcement comprising a plurality of reinforcing elements the Young's modulus of monoaxial extension of the flexible matrix being greater than and equal to 1 MPa and less than or equal to 100 MPa, and preferably greater than and equal to 1.5 MPa and less than or equal to 50 MPa, and even more preferably higher and equal to 2 MPa and less than or equal to 10 MPa, the Young's modulus of monoaxial expansion of reinforcing elements being greater than or equal to 5 GPa (and preferably greater than or equal to 10 GPa). in which the Young's modulus of monoaxial extension of the rigid matrix is greater than or equal to 5 GPa. According to a first embodiment, the contact between the axially central portion and each intermediate portion is via an end of the axially central portion which enters the intermediate portion. This end of the axially central portion may in particular include an extra thickness to anchor the end in the intermediate portion. According to a second embodiment, which is advantageously combined with the first embodiment, the contact between each distinct lateral part of the axially central part and the intermediate part in contact with it is also done by one end of the part. side that enters the middle part. This end of the side portion may also have an extra thickness to anchor the end in the intermediate portion. According to a third embodiment, each distinct lateral portion of the axially central portion is completely covered with the material constituting the flexible matrix of the intermediate portion in contact therewith. This embodiment makes it possible to increase the contact surface, to improve the contact between the lateral part and the intermediate part. On the other hand, a too steep transition can serve as a starting point for a crack or a takeoff. According to a fourth embodiment, the reinforcing reinforcement is a textile or metal reinforcing reinforcement. This frame may comprise radially arranged wire reinforcing elements. Alternatively, it may comprise two layers comprising wire reinforcing elements, the reinforcing elements of each layer being parallel to each other and crossed from one layer to another. The reinforcing armature of each intermediate portion may advantageously comprise cables each having two ends, one end being secured to the axially central portion and the other end being secured to a side portion. In an advantageous variant, the cables are welded to the axially central portion and to a lateral portion. According to a fifth particularly advantageous embodiment, the rim comprises two intermediate parts, and the two intermediate parts are symmetrical with respect to each other. The material constituting the flexible matrix of each intermediate portion may in particular be polyurethane, a rubber composition or a thermoplastic elastomer. Polyurethane and thermoplastic elastomers have the advantage of being injected. Due to their rigidities, the polyurethanes are particularly suitable for use as an intermediate part. The material constituting the rigid matrix of the axially central part and of the two lateral parts may in particular be a metal or a metal alloy. It is particularly advantageous to provide that the Young's modulus of monoaxial extension of the rigid matrix is greater than the Young modulus of monoaxial extension of the flexible matrix by a factor of greater than or equal to 100. Thus the lateral parts are actually floating and the forces transmitted during a shock are lower. Of course, it may be advantageous to combine several or even all the embodiments mentioned. BRIEF DESCRIPTION OF THE DRAWINGS [0018] FIG. 1 represents, in radial section, a tire-wheel assembly. Figures 2 to 6 each show a portion of a rim according to the invention [0020] All figures are schematic.
    [0002] DETAILED DESCRIPTION OF THE INVENTION [0021] In the use of the term "radial" it is appropriate to distinguish several different uses of the word by the person skilled in the art. First, the term refers to a radius of the rim (and the tire of which it is equipped). It is in this sense that a point P1 is said to be "radially interior" at a point P2 (or "radially inside" of the point P2) if it is closer to the axis rotation than point P2. Conversely, a point P3 is said to be "radially external to" a point P4 (or "radially outside" of the point P4) if it is farther from the axis of rotation of the tire than the point P4. We will say that we are advancing "radially inwards (or outwards)" as we move towards smaller (or larger) radii.
    [0003] When it comes to radial distances, this sense of the term also applies. In contrast, a wire or an armature is said to be "radial (e)" when the wire or reinforcing elements of the reinforcement make with the circumferential direction an angle greater than or equal to 80 ° and less than or equal to 90 °. Clarification that in this paper, the term "wire" is to be understood in a very general sense and includes threads in the form of monofilaments, multifilament, cable, twisted or equivalent assembly, and this regardless of the material constituting the wire or the surface treatment to promote its connection with the rubber. Finally, by "radial section" or "radial section" here means a section or section along a plane which contains the axis of rotation of the rim (and the tire of which it is equipped). An "axial" direction is a direction parallel to the axis of rotation of the rim (and the tire of which it is equipped). A point P5 is said to be "axially inner" at a point P6 (or "axially inside" of the point P6) if it is closer to the median plane of the rim than the point P6. Conversely, a point P7 is said to be "axially outside at" a point P8 (or "axially outside" of the point P8) if it is further away from the median plane of the rim than the point P8. The "median plane" of the rim is the plane which is perpendicular to the axis of rotation of the rim and which is equidistant from the rim seats intended to receive a bead of a tire. A "circumferential" direction is a direction that is perpendicular to both a radius of the rim and the axial direction. As part of this document, the expression "rubber composition" means a rubber composition comprising at least one elastomer and a filler. By "Young modulus of monoaxial extension" of a material is meant here the expansion module measured from a tensile test. For flexible dies and textile reinforcement elements, according to DIN EN ISO 527-2, a type A test piece according to DIN EN ISO 3167 is used with a crosshead speed of 1 mm / min. For rigid dies and metal reinforcing elements, on the other hand, ASTM E111-04 (2010) is used. [0028] Figure 1 shows, in radial section, a tire-wheel assembly comprising a tire 5. The tire 5 is mounted on a hollow mounting rim 10 complies with the standards of the ETRTO (European Tire and Rim Technical Organization). The common axis of rotation bears the reference numeral 1. [0029] FIG. 2 represents, in radial section, a part of a rim 10 according to the invention. This rim 10 comprises an axially central portion 20 comprising a disc (not shown), two lateral parts 31 and 32 and an intermediate part 41. The lateral part 31 is distinct from the axially central part 20 while the lateral part 32 is of a room with this one. Each of the side portions 31 and 32 is provided with a rim seat for receiving a bead of a tire (not shown). The axially central portion 20 and the two lateral portions 31 and 32 are made in a rigid matrix that can be reinforced by a reinforcing reinforcement. In this case, these parts are made of steel whose Young's module of monoaxial extension is equal to 190 GPa. The intermediate portion 41 forms the only mechanical link between the axially central portion 20 and the lateral portion 31; it is made of a flexible matrix, in this case made of polyurethane, reinforced by a reinforcing reinforcement. The Young's modulus of monoaxial extension of the flexible matrix is in this case equal to 90 MPa. Figure 3 shows, in radial section, a portion of a rim 10 according to another embodiment of the invention. Unlike the rim of Figure 2, the two side portions 31 and 32 are distinct from the axially central portion 20 and there are two intermediate portions 41 and 42 made of polyurethane. Figure 4 shows, in radial section, a portion of another rim according to the invention. Here, the contact between the axially central portion 20 and the intermediate portion 42 is through an end 21 of the axially central portion 20 which enters the intermediate portion 42. Similarly, the contact between the lateral portion 32 (which is distinct from the axially central portion 20) and the intermediate portion 42 in contact therewith is an end 34 of the lateral portion 32 which penetrates into the intermediate portion 42. The intermediate portion 42 comprises a reinforcing reinforcement 50 textile embedded in the flexible matrix . This reinforcing armature 50 consists of radially arranged nylon threads. It would also be possible to use PET, aramid, rayon, fiberglass, carbon or basalt wires, PEN or PVA, etc. Figure 5 shows, in radial section, a portion of another rim according to the invention. In this case, the end 21 of the axially central portion 20 has an extra thickness 22 for anchoring the end in the intermediate portion 42. Similarly, the end 34 of the side portion 32 has an extra thickness 33 allowing anchoring the end 34 in the intermediate portion 42. In addition, the side portion 32 (which is distinct from the axially central portion 20) is completely covered with the material constituting the flexible matrix of the intermediate portion 42 in contact therewith. The reinforcing reinforcement of the intermediate portion comprises two layers 51, 52 comprising wire reinforcing elements, the reinforcing elements of each layer being parallel to each other and crossed from one layer to another. It is in this case Kevlar fibers having a Young's module of monoaxial extension equal to 35 GPa. Figure 6 shows, in radial section, a portion of another rim according to the invention. Here, the reinforcing reinforcement of the intermediate portion 42 comprises cables 60 each having two ends 61 and 62, the end 61 being secured to the axially central portion 20 and the end 62 being secured to the lateral portion 32. In this case, these cables are welded to the axially central portion 20 and to the lateral portion 32. Again, the lateral portion 32 (which is distinct from the axially-central portion 20) is completely covered with the material constituting the matrix. flexible of the intermediate portion 42 in contact therewith. Tests were carried out with a rim having two flexible intermediate parts corresponding to Figure 4, the intermediate portion being made of polyurethane having a Young's modulus of 90 MPa, reinforced by nylon son having a Young's modulus of 5.1 GPa. The wheel was mounted on the front axle of a Peugeot 307 HDI vehicle. Noise measurements have shown significant attenuation of perceived noise in place of the driver in the bands 80-100 Hz, 140-170 Hz and 340-380 Hz, compared to a wheel with an equivalent rim devoid of intermediate parts flexible. Curb shock tests also confirmed an improvement in the resistance of the tire-wheel assembly to shocks.
