    专利说明:

    [0001] [0001] The invention relates to a rolling assembly formed mainly of a tire, a rim and an 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 order to reduce the carbon dioxide emissions of motor vehicles, manufacturers want to reduce the mass of these vehicles but also the rolling resistance of their tires. The reduction of this rolling resistance can be achieved by increasing the outer diameter of the tires and therefore that of the wheels. But this causes an increase in the mass of the wheel and therefore that of the vehicle. Also a known solution is to use lighter materials than steel to form the rim, such as aluminum alloys. But such rims, if they are lighter and have a more airy visual appearance facilitating the release of heat from the brakes, are not sufficiently resistant to shocks, such as potholes and / or sidewalks. P10-3416 Indeed, shocks caused on such rolling elements can cause the rupture of one or more components of the rolling element (tire and / or rim). Also there remains the need to have a lighter rolling assembly that rolling assemblies whose rim is steel, and which has a better impact resistance due to better protection of the tire, while maintaining a high level of tire handling performance, in particular its ability to develop significant drift. The invention therefore relates to a roller assembly having an axis of rotation and comprising: - a tire having two beads, - a narrow rim J whose width is at most equal to 50% of the maximum axial width of the tire inflated to its operating pressure, - two adapters each ensuring the junction between one of the beads and the rim said rim having two rim seats, said adapters each having: - an axially inner end to be mounted on the seat of the rim 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 connection between said outer reinforcement and said inner reinforcement, P10-3416 - substantially cylindrical adapter seat device for receiving one of said beads, said seat being located at the axially outer end of said body; - an adapter bearing face substantially comprised in a plane perpendicular to the axis of rotation, said bearing face; being located on the axially inner face of the axially outer end, said adapters being made of rubber compounds reinforced and deformable elastisquement at least in the radial and axial directions. The adapter is characterized in that the rim is made of a material selected from alloys of aluminum and / or magnesium, composite materials based on carbon fibers, glass fibers, fiberglass and fiberglass. aramid, of plant fibers, said fibers being comprised in a matrix based on thermosetting compounds or thermoplastic compounds, or in a complex compound comprising an elastomer and a complex based on resin and fibers selected from carbon fibers, fibers of glass, aramid fibers, vegetable fibers or from any combination of materials. The assembly of the invention has the advantage of being simple constitution and assembly. The adapter of the assembly according to the invention also makes it possible, by increasing the clamping under the beads of the tire, to prevent its rotation on the adapter in strong lateral stress. Finally, the adapter of the assembly according to the invention has the advantage of significantly reducing the level of mechanical forces to the chassis during a shock, and thus to reduce the mass of the vehicle. An elastically deformable adapter is to be understood in the radial and axial directions, an adapter allowing, in the radial direction, a clearance between the bead of the tire and the mounting rim of at least 5% of the deflected tire deflection. at the recommended load and pressure, and in the axial direction, an approximation of the bead of the rim of a value at least equal to 15mm P10-3416 at zero pressure, said deformations being canceled if the constraints or forces which are are the cause. [0013] Preferably, the fiber-based composite materials comprise fibers having a length greater than or equal to 5 mm. The matrix based on thermosetting compounds is preferably chosen from epoxy resins, vinylester, unsaturated polyesters, cyanate ester, bismaleimide, acrylic resins, phenolic resins, polyurethanes and combinations thereof. The matrix based on thermoplastic compounds is preferably chosen from polypropylene (PP), polyethylene (PE), polyamides (PA), semi-aromatic polyamides, polyester (PET) and polybutylene terephthalate ( PBT), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), polyethersulfone (PSU), polyetherimide (PET), polyimide (PI), polyamideimide (PAT), polyphenylenesulfide (PPS), polyoxymethylene (POM) , polyphenylene oxide (PPO). The narrow rim may be of different kinds: it may be constituted, as known per se, two wheel seats axially extended externally by two rim flanges directed radially outwardly and joined axially to the inside by a mounting groove. The presence of a mounting groove may prove to be unnecessary; the two seats can then be axially and radially extended inward by two radial disks joined by bolts. The two seats can also be extended axially and radially by two radial annular disks, axially spaced and allowing the attachment of a bead plate that can complete the rim and can possibly serve as a support support of the tread in the case of rolling the tire at low pressure or zero, said plate being circumferentially composed of several independent parts. The mounting rim may also be of the rim type with rims directed radially inwards, as described and shown in document FR 2, P10-3416 610, 872, the beads of the tire being received on the rim seats by inside. The adapter between a tire bead and the narrow mounting rim mainly consists of a bead ensuring the attachment of the adapter to the rim, a main reinforcing armature for deformation at least in the two radial and axial directions, and creating the actual connection between the bead and a metal adapter reinforcement for receiving the tire bead. The constitution of the bead of the adapter is a function of the fastening system of the mounting rim, but mainly comprises a circumferential anchoring ring that can be a simple ring of rubber mixture reinforced or not, a rod or a stack of circumferentially oriented reinforcing elements. Around said anchoring ring and by turning over, or between the reinforcement elements of the ring and by clamping, is anchored the reinforcing reinforcement of the adapter. Said armature may be formed of the same constituents as those used for a known tire carcass reinforcement, that is to say formed of one or more plies of radial reinforcing elements or crossed from one ply to the next. making with the circumferential direction of the tire a given angle. Said reinforcing elements may be textile and / or metal and / or plastic, in the form of monofilaments and / or cables and / or blades. The reinforcing armature of the adapter is joined to a metal adapter reinforcement. The term "adapter metal reinforcement" means an assembly formed of at least one rim seat, said seat possibly being extended axially to the outside by a rim flange, said rim being able to have a low height and a usual shape, particular curved at its end. The adapter reinforcement is embedded in a rubber mixture, and the edge of the reinforcing reinforcement of the adapter is anchored to said reinforcement either by superposition radially outward or by winding around the rim if it exists, the bead of the tire being pressed to the mounting on said reinforcing armature of the adapter. P10-3416 [0019] Preferably, the rolling assembly according to the invention comprises a first and a second adapter each having a body of different or identical length. The invention will now be described with the aid of the examples and figures which follow and which are given by way of illustration, and in which: - Figure 1 shows schematically and in meridian section a first variant of the assembly according to the invention, - Figure 2 shows schematically and in meridian section a second variant of the assembly according to the invention - Figure 3 schematically shows, seen in meridian section, a third variant of the assembly according to the invention, - Figure 4 shows schematically, seen in meridian section, a fourth variant of the assembly according to the invention. FIG. 1 represents a rolling assembly which comprises a tire P (partially shown), an adapter A and a rim J. The design tire, itself unchanged in the invention, is formed of a tire strip. reinforced bearing by a crown reinforcement joined to two beads B on either side of an equatorial plane XX 'through two sidewalls 13. A carcass reinforcement 10 mainly reinforcing the sidewalls 13 is anchored in each bead B at least one rod, here of "braided" type 11 to form reversals 12, separated from the main carcass reinforcement portion by quasi-triangular shaped profiles 15. [0023] It is important to note that the The invention can be implemented with many types of tires, whether radial or diagonal carcass, or even with self-bearing sidewall type tires. The aluminum rim J according to the invention comprises a groove 30, said assembly, and bringing together on either side of the equatorial plane, two rim seats 31 P10-3416 whose frustoconical generatrices are with the axis. 5 ° rotation angle, said seats being axially outward extended by rim flanges 32 whose radially outer edges are curved. The particularity of the rim J is its axial width "1", said width being equal, in the case studied, to 45mm, and much less than 50% of the maximum axial width of the tire mounted and inflated to its recommended pressure . Between the rim J and the bead B of the tire, is arranged an adapter A consisting mainly of an outer reinforcing element 20, joined to an axially inner end of the adapter 22 by a reinforcing reinforcement 21. The reinforcement 20 metal in the present example, but which could be of plastic material or of composite material, such as a resin reinforced by fibers of any kind, has a compression module equal to or substantially equal to its extension module. It is formed of a seat 201 inclined relative to the axis of rotation by an angle of 5 °, and extended axially and radially to the outside by a flange 202, the dimensions of said elements being normalized whether it is the height of the flange 202 or the axial width of the seat 201. The walls of the reinforcement 20 are treated, for example brassed in the studied case of metal reinforcement, to allow proper adhesion with the rubber mixtures used in the main reinforcing reinforcement 21 and with any additional reinforcement of the adapter A. The main frame 21 is formed of a sheet of polyamide aromatic textile cables, parallel to each other in the sheet and radial. Said sheet is, on the one hand, axially contiguous inside and radially on the outside to the walls of the metal reinforcement 20, and on the other hand, anchored in each axially inner end 22 of adapter to an annular element 23 of bead reinforcement, such as a bead wire, to form an upturn 24. [0028] The main reinforcement 21 is completed by additional reinforcement: in the axially inner end 22, axially outside the main part of the reinforcement ply 21 and its upturn 24, is disposed a first ply 26 of bead reinforcement, formed of a polyamide P10-3416 aliphatic fabric formed of reinforcing elements, parallel to each other in each layer of fabric and crossed between them; on the side of the reinforcement 20 is disposed an additional reinforcement 25 formed of a fabric identical to the previous one formed of two layers of textile elements made of aliphatic polyamide, parallel to each other in each ply and crossed from one layer to the next, making with the circumferential direction at an angle of 45 °, said armature 25 partially covering the axially inner wall and then the upper end and the axially outer wall of the flange 202 and finally the radially inner wall of the seat 201 to have an edge attached to the main reinforcing ply 21, the edge whose end is distant from the equatorial plane by an amount less than the distance separating from said plane the axially inner end of the seat 201. The adapter A is completed, on the one hand, by a layer 27 of mixture a rubbery protective covering on the outside of the reinforcement 20, the radially inner face of the adapter and providing the connection with the hook of the mounting rim J surrounding the frames 21 and 26, and secondly, on its radially inner face intended to be in contact with the inflation gas of the assembly, by an inner layer 28 of mixture impervious to said gas. The assembly shown in Figure 2 differs from that of Figure 1 by the following points: - The tire P has beads whose seats are inclined relative to the axis of rotation of the assembly of a angle equal to 20 °, and reinforced by rods of rectangular wire type; - The mounting rim J has a mounting groove 30 facing the inside of the assembly, rim seats 31 inclined relative to the axis of rotation by an angle of 15 °, said seats 31 being extended axially externally and radially inwardly by rim flanges 32 with curved edges, said rim receiving the axially inner ends of the adapter from the inside, and - the adapter comprises: P10-3416 o D ' a metal outer reinforcement 20, formed of a seat 201 inclined relative to the axis of rotation of the assembly, an angle equal to 15 ° and extended axially and radially outwardly by a flange 202, the other dimensions of said elements being normalized whether the height of the flange 202 or the axial width of the seat 201, o A main reinforcing armature 21 formed of two plies of textile cables 21 'and 21 "polyester, parallel to each other in each tablecloths but crossed a 21 'to the next 21' making with the circumferential direction of the assembly an angle of 45 °, said plies being as previously on the one hand contiguous axially inside and radially outside the pretreated walls of the outer reinforcement 20, and secondly anchored in each axially inner end 22 of adapter to an annular element 23 reinforcing the axially inner end, such as a rod, to form reversals 24 'and 24 "whose ends are axially offset with respect to each other, o additional reinforcement completing the main reinforcement 21: on the side of the outer reinforcement 20 is disposed an additional reinforcement 25 formed of the same fabric as previously of textile elements, said armature 25 partially covering the axially inner wall and then the upper end then the axially outer wall of the flange 202 and finally partially the oi radially inner seat 201 to have an edge attached to the main reinforcing ply 21, the edge whose end is distant from the equatorial plane by an amount less than the distance between said plane the axially inner end of the seat 201, o The adapter A is also completed, on the one hand by the layers of rubbery protective mixtures 27, and on the other hand on its radially inner face by the inner layer 28 of impermeable mixture to said gas. P10-3416 The assembly of Figure 3 differs from the assembly of Figure 1 by the constitution of the axially inner end 22 of the adapter A and the constitution of the attachment system of the end axially inner on the mounting rim J. The said system is indeed composed of two elements: the actual rim J and a bead clamp S. The rim J is formed of two usual flanges 32, extended radially inside and axially internally by two flat 31 rim seats, themselves extended radially inwardly by two radial annular discs 33 having between them a certain axial spacing. In said spacing are housed the radially movable discs 41 of at least three parts 42 which, joined circumferentially, form the plateau of the bead clamp S, the axial width of the plate is sufficient to allow the clamping and jamming of the beads on the Rim seats 31. The plate 42 may also advantageously serve to support the tire tread of the assembly when said tire rolls at low pressure or even zero. As for the constitution of the axially inner end of adapter A, it is adapted with respect to its composition and shape to the attachment principle described above; in particular it is advantageous for the reinforcing ply 21 of the adapter to be anchored by winding around a rubber ring 23 with a high compression modulus but extending in the circumferential direction. Furthermore, on the side of the external adapter reinforcement 20 is provided an additional reinforcement 25 formed of a fabric identical to the previous one formed of two layers of aliphatic polyamide elements, parallel to each other in each layer and crossed from one layer to another. the next one making with the circumferential direction an angle of 45 °, said armature 25 partially covering the axially inner wall and then the upper end then partially the axially outer wall of the flange 202 to have an end located at a radial distance approximately equal to the distance between said axis and the middle of said flange. Figure 4 shows a last embodiment. The tire P is identical to that shown and used in the assembly according to Figure 2. The mounting rim J is a so-called multi-piece rim of which at least two parts are movable. Such a rim is the same type as the rims used for the assembly of P10-3416 some tires "heavyweight" and "civil engineering". Said rim is mainly composed of a rim bottom 300 which can be flat, said rim bottom being extended on one side of the rim by a conical seat itself extended by a circle or rim flange, seat and flange being said fixed side (not shown). On the axially opposite side, a single movable piece 31, formed by a rim 302 and a conical ring 301, can be threaded onto the rim bottom after the bead 22 of the adapter A has itself been brought onto the rim. the bottom of rim. An O-ring 304, to seal the assembly, and a locking ring 303 to lock the assembly on the rim bottom, complete the piece 31. It is obvious that any axially inner end 22 of however it may be, can be mounted on such a rim. The example described relates to a preferred embodiment where the radial carcass reinforcement 21 of the adapter A, composed of a sheet of radial textile cords, and its upturn 24 are sandwiched between the frustoconical seat of the mobile ring 301. rim and a reinforcement ring 33 having a radially inner face itself frustoconical, the generatrix of said face forming with the axis of rotation the same angle as that made by the generatrix of the seat of the movable conical ring of the workpiece 31. The upturn 24 of carcass reinforcement 21 is obtained by winding said armature around a circumferential ring 23 having a small cross-sectional area and a low resistance to tension, said ring 23 being used only to perfect the locking of the carcass reinforcement between the two frustoconical surfaces of the ring 33 and the seat of the conical ring 301. It is possible, in particular in the case of using such a rim, to connect the two adapters left and right by a rubber compound element simply vulcanized and / or reinforced while remaining elastic. Example: Tests on sidewalk P10-3416 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). The test is carried out 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 set without adapter and with a conventional steel rim (control 1) is compared to an adapter assembly according to W000 / 78565 (control 2), and to an assembly provided with an adapter and an adapter. composite rim 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 - Impeller with marks - Adapter plastically deformed wheel intact Table I Results greater than 100 show a improved behavior in the event of a side impact. P10-3416 The test carried out on the sidewalk height of 90mm results in the puncture of the control tire at a speed of 30km / h, whereas the assembly according to the invention undergoes no damage at this same speed, or even a speed of 50km / h. The test performed on the sidewalk 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, even at a speed of 50km. / h.
