Definitions
- the present invention relates to the technical sector of safety supports intended to be mounted on a rim inside a tire fitted to a vehicle, to support the tread of this tire in the event of loss of inflation pressure.
- US Patent 5,685,926 describes a non-pneumatic tire comprising a cellular structure with radial cells of various shapes.
- radial cells is meant cells whose walls extend in a direction passing substantially through the axis of rotation of the structure and perpendicular thereto.
- the walls of the cells of this structure are produced by assembling plates of constant and wavy thickness (see FIG. 8 of the document). As a result, these walls of the cells have a thickness systematically doubled in the bonding zones and constant in the rest of the structure, which limits the optimization of this structure.
- the buckling resistance i.e. resistance to axial extension of the body or bulkheads under radial load
- the lifespan of the support depends greatly on it.
- the subject of the invention is a safety support intended to be mounted on a rim inside a tire fitted to a vehicle, to support the tread of this tire in the event of loss of inflation pressure, comprising: a substantially cylindrical base intended to fit around the rim;
- a substantially cylindrical top intended to come into contact with the tread in the event of loss of pressure, and leaving a clearance with respect to the latter at nominal pressure;
- annular body connecting said base and said vertex; such that said support is produced, at least in part, by axial assembly of a plurality of annular sections and such that each of said annular sections comprises, regularly distributed around the circumference, substantially axial orientation connecting walls extending to the less on a part of said annular body and intended to cooperate with the connecting walls of the adjacent annular section or sections to assemble said annular sections axially.
- the connecting walls can extend radially at least over part of the annular body. They may also include connecting walls extending circumferentially at least over a part of the annular body.
- the assembly takes place by abutment of the axial ends of the connecting walls.
- the annular sections comprise partitions arranged at the level of the annular body, extending radially between the base and the top of the support, and forming a circumferentially continuous support element.
- each partition of the line broken by a connecting wall can be extended substantially axially to constitute, after assembly of the annular sections, cells of hexagonal section in the form of a honeycomb.
- the thicknesses of all the walls can easily be identical or not, depending on the choice of the designer of the support.
- the hexagonal cells obtained can be regular hexagons. It is this structure which has the best buckling resistance during radial loading.
- the partitions can also constitute support elements in the form of a circumferential veil to constitute, after assembly of the annular sections of the cells of rectangular section.
- the partitions can also constitute support elements in the form of a sinusoidal line.
- the annular sections may include partitions forming circumferentially discontinuous support elements.
- such partitions may comprise radial partitions which are inclined axially to constitute, after assembly, support elements for the annular body of the support in the form of chevrons.
- radial partitions which are inclined axially to constitute, after assembly, support elements for the annular body of the support in the form of chevrons.
- Each partition of the annular sections can, axially at least on one side, be extended axially by a connecting wall.
- each axial end of the partitions can constitute the connecting wall.
- the annular sections according to the invention can also comprise a usual top which is circumferentially continuous.
- This vertex can also be circumferentially discontinuous.
- a discontinuous apex reduces the bending stiffness of the support even more appreciably, which facilitates the mounting and dismounting of the assembled tire / support / wheel assembly.
- the annular sections can have connecting walls which radially include the top of said section. This allows to have a support assembled with an axially continuous top.
- the connecting walls can also stop radially at the level of the vertex.
- the vertex can also be discontinued axially.
- the discontinuities of the apex are arranged radially outside the walls of the cells of the annular body.
- the supports according to the invention can be produced with support edges having a circumferentially continuous base.
- the base of these supports includes means for resisting centrifugal forces.
- each of the annular sections of a support may include a part of these means of resistance to centrifugation.
- the supports according to the invention may include annular sections assembled by gluing.
- These supports may advantageously include annular sections made of a thermoplastic elastomer and assembled by mirror welding. The assembly can also be carried out by ultrasonic welding.
- the annular sections can also be assembled by mechanical clipping of the connecting walls.
- the annular sections disposed axially on the outside of a support may comprise connection walls only on one axial side. These sections can also be produced with a material of rigidity greater than that of the material constituting the other annular sections.
- the supports according to the invention may also include annular sections produced by assembling a set of segments of annular sections.
- the number of these segments can be between 2 and 30. When the number of these segments is high, close to 30, the segments can then be injected pattern by pattern of the support elements or of the crown.
- the supports according to the invention can comprise from 2 to 14 annular sections.
- the assembly of two annular sections already gives a very appreciable freedom of design of the support and when the number is close to 14, each section has an axial width of the order of 10 mm, it is then a very easy object to be made by injection.
- the subject of the invention is also a safety support intended to be mounted on a rim inside a tire fitted to a vehicle, to support the tread of this tire in the event of loss of inflation pressure, comprising: - a substantially cylindrical base intended to fit around the rim; - A substantially cylindrical top intended to come into contact with the tread in the event of loss of pressure, and leaving a clearance with respect to the latter at nominal pressure; and
- An annular body comprising support elements of substantially radial orientations connecting said base and said vertex; characterized in that said support elements extend substantially axially from one side to the other of said annular body of said support and have at least two reversals of the direction of their curvature.
- Such supports comprising axial recesses cannot be produced in a single operation by injection into a mold due to the existence of areas of the support arranged in undercut.
- Such support can be achieved using a technology close to that of the tires themselves, either by injecting the base and the annular body of the support in a mold comprising molding elements with radial displacements; after molding the annular body and the base of the support, the assembly should be overmolded with a top.
- Such supports can also be produced by axial assembly of annular sections.
- the support elements have a chevron shape, straight or rounded.
- the invention also relates to an annular section suitable for constituting a support according to the invention; as well as an annular wafer segment suitable for forming an annular wafer after assembly.
- FIG. 1 is a side view of a safety support

- FIG. 17 shows a support close to that of Figure 13 with a circumferentially discontinuous apex;
- - Figure 18 shows, in side view, a support similar to that of Figures 10 and 11;
- - Figure 19 schematically illustrates an assembly of annular wafer segments into an annular wafer.
- Figure 1 shows a side view of a safety support 1 described in document WO 00/76791.
- This support essentially comprises three parts: - a base 2, of generally annular shape; a crown 3, substantially annular, intended to support the tread of a tire in the event of a loss of pressure thereof, with on its radially outer wall (optionally) longitudinal grooves 5; and - an annular body 4 for connection between the base and the top.
- FIG. 1 also specifies the geometric conventions used in the present application.
- the X axis passing through O is the axis of rotation of the support. After mounting the support in the tire cavity and around a rim, the X axis is also the common axis of rotation of the support, the tire and the rim.
- the direction R is a radial direction, that is to say passing through the axis X and perpendicular to it.
- Direction C is a circumferential direction. At any point on the support, tire or rim, this circumferential direction is perpendicular to the radial direction passing through this point as well as to the X axis.
- This support 1 is intended to be mounted around a preferential rim 6 as shown in FIG. 2 and inside the cavity 8 of a corresponding tire 7. Such a rim is described, in particular, in patent application EP 0 796 747.
- FIG. 2 illustrates the function of the safety support 1 which is to support the tread of the tire in the event of a large loss of inflation pressure in the cavity 8.
- Figures 3 a and b show in partial perspective an annular edge 10 of support according to the invention.
- Figure 3a is a bottom view and Figure 3b a top view.
- These annular sections 10 comprise a base 12, an apex 13 and an annular body 14.
- This annular body 14 consists of partitions 16 extending radially between the base and the apex and forming a support element in the form of a continuous broken line. circumferentially.
- at each end of a partition 16 is a connecting wall 15 extending substantially axially towards the outside of the annular section. This connecting wall 15 extends radially over the whole of the annular body 14.
- the top 13 of the wafer 10 is circumferentially continuous but includes notches 17 arranged radially outside the areas of connection of the top with the partitions 16 and the walls of connection 15.
- the base 12 preferably comprises means of resistance to centrifugation such as reinforcing wires oriented substantially circumferentially.
- reinforcing threads can be made of polyaramid, fiberglass or metal. These means can also be reinforcement grids such as those described in application WO 02/24476.
- FIG. 4 shows in partial perspective a safety support 100 obtained by axial assembly of five annular sections 10.
- This support thus comprises a base 102 which is circumferentially continuous, an apex 103 which is also continuous circumferentially and comprising notches 105 and an annular body 104 made up of radial cells with hexagonal walls in the form of honeycomb 106.
- the connections between the annular sections are made at the level of the adjacent connection walls. These connections can be obtained by any known process, in particular welding or bonding or clipping. This process varies according to the nature of the material of the annular sections.
- the notches 105 are obtained by axial assembly of two notches 17 adjacent to the top of the annular sections 10.
- the presence of the notches in the top has the advantage of reducing the weight of the support 100 but also of limiting its overall stiffness in bending. which facilitates its introduction into the toric cavity 8 of the tire 7 first stage of assembly on the rim 6, as indicated in application FR 2720977.
- the invention is thus based on the concept of manufacturing “annular sections” of support, then their assembly side by side, to give support 100.
- the very great advantage of this solution is to allow injection molding, then an easy demolding of these annular sections 10.
- the only condition for obtaining an easy demolding of the annular sections is that there is no undercut part of the partitions 16. Consequently, the shape of the partitions of the annular body 104 of the support 100 may be almost arbitrary with regard to the release constraints, and in any case may be chosen from a very large number of practical forms, infinitely superior to those which one could choose in the prior art.
- This solution involving the welding or assembly of annular support edges allows a weight gain of up to about 30%. It should be noted that the annular sections 10 may or may not have a base 12.
- the annular sections can be injection molded, assemble them axially to obtain a support portion. then overmolding a base including, if necessary, the appropriate reinforcement means to resist centrifugation while driving. This process also applies in the case of annular sections having no vertex.
- the partitions 16 of the annular body 14 of the annular sections 10 may in particular be flat or adopt any shape allowing easy demoulding, with a variable inclination relative to the circumferential median plane P. This almost absence of demolding constraints allows the '' skilled in the art of designing the partitions as well as the base and top with great freedom in "design", which allows the weight of the final support to be optimized with great efficiency with regard to the properties targeted.
- the invention makes it possible to conceive of many forms and variants which are possibly cumulative, as will be readily known to the skilled person.
- each annular section can be identical or different: different shapes can be provided, and / or different inclinations of the partitions with respect to the circumferential median plane P, and / or thicknesses of different materials either at the same partition, or between two partitions of different annular sections.
- thermoplastic elastomers more or less stiff depending on the position relative to the lateral edges, or even different materials between the top and the body or the base, and similar combinations.
- the only condition being naturally that all the materials can be assembled by welding, or by other methods such as ultrasonic welding, or even by mechanical clipping, without any problem other than adaptations.
- annular section or sections forming the central part of the support (that is to say the annular section or sections containing the circumferential median plane P or neighboring of this plane P) will comprise partitions of greater thickness than that of the partitions of the lateral annular sections, that is to say forming the edges of the support or close to this edge. This is to improve the buckling resistance under radial compression load.
- FIG. 5 shows in section AA as indicated in FIG. 1, the partitions 21 of annular sections 20. As in the previous example, these partitions 21 are arranged circumferentially in the form of a continuous broken line. At each end of a partition 21 is an axially oriented connecting wall 22.
- FIG. 6 illustrates, still in section AA as indicated in FIG. 1, a support 200 obtained by axial assembly of four annular sections 20.
- This support is made of a thermoplastic material and the assembly is carried out by welding the walls of adjacent connection 22.
- FIG. 6 b schematically shows the connection zone between two adjacent walls 22 after bonding.
- the connecting walls have practically given only this connecting zone 202 with a bulge 203 on either side of the connection zone 202.
- the two annular sections 20 disposed at the edge of the support did not have connection walls to the outside.
- the annular body 204 of this support 200 thus consists of radial cells 205 of general shape of parallelograms.
- plane P circumferential median plane.
- Figures 7, 8 and 9 show supports obtained by assembling four annular sections similar to that presented in Figure 5 but with connecting walls of different axial lengths.
- FIG. 9 shows a support 500 which is the assembly of four annular sections 50 comprising partitions 51 in the form of a circumferentially continuous broken line and connecting walls 52 of length 1/2 at each end of the partitions 51.
- the length 1/2 is the useful length, that is to say the axial length resulting after assembly.
- the initial length must be greater by a variable value depending on the assembly process and the material of the annular section.
- the annular body 504 of the support 500 therefore comprises radial cells 505 hexagonal in the shape of a regular honeycomb.
- This support 500 has excellent buckling resistance under radial compression load, particularly in its central part.
- the support 400 of Figure 8 consists of the assembly of two annular sections 40 whose connecting walls 42 on either side have a length of 1, identical to the length of the partitions 41 and two annular sections 45 whose connecting walls 47, 48 have on one side an axial length of / (48) and the other of 1/2 (47), arranged at the edge of the support.
- Figures 10 and 11 show two other examples of supports 600 and 700 obtained by assembling annular sections 60, 70, comprising partitions 61, 71, in the form of a circumferential web with connecting walls of asymmetrical axial lengths (62, 63 , 72, 73).
- the annular edge 60 has connecting walls 62 and 63 axially aligned, which gives support with radial cells 601 of rectangular shape and axially and circumferentially aligned.
- the annular edge 70 has connecting walls 72 and 73 circumferentially offset. Consequently, the support 700 has radial cells 701 of rectangular shape and circumferentially aligned but offset axially. This allows a better homogeneity of distribution of the forces.
- FIGS 12 a and b similar to the previous figures show an annular edge 80 with partitions 81 in the form of a sinusoid.
- the connecting walls 82 are axially limited to the amplitude necessary to obtain a good connection.
- This figure also schematically indicates the cutting of the top of the annular sections and of the support. This top comprises notches 807 intended as previously to limit the mass and to reduce the stiffness of the support.
- Figures 13 and 14 show annular sections 90 and 95, the partitions 91 and 96 no longer form a circumferentially continuous support element, but discontinuous and of flat shape inclined relative to the axial direction.
- the annular section 90 has partitions 91 of alternating orientations relative to the median plane P, the section 95, partitions 96 of identical orientation over the entire circumference.
- the bases 93 and 97 of the annular sections have also been shown. These bases are circumferentially continuous and injected at the same time as the partitions and connecting walls.
- FIG. 13b a support 900 obtained by assembling four sections 90 whose annular body 904 comprises support elements 905 extending axially from one edge of the support to the other substantially axially with four changes curvature.
- Such support is impossible to obtain by a molding technique in a single operation because of the impossibility of unmolding the object axially.
- the base of the support is not shown. It should be noted that the bases 93 of the annular sections, after assembly will not be contiguous if the connecting walls 94 are not completely absorbed by the welding process, or if the walls are assembled by another technique such as bonding or clipping.
- This support 950 comprises support elements 951 in the form of chevrons.
- the different axial length of the connecting walls 98 and 99 on either side of the annular sections 95 results in the widest walls a greater resulting spacing after assembly.
- the connection walls 98 are not oriented strictly axially but in the extension of the partitions 96. This also makes it possible to achieve good connection and geometry after assembly of the support elements in the form of chevrons.
- FIG. 15 shows, in partial perspective view, a third example of support 960 with support elements 961 in the form of chevrons.
- the base 962 of this support comprises four adjacent portions, axially discontinuous, corresponding to the bases of the annular sections used for assembly.
- This figure shows an example of assembly by bonding of the connection zones 963.
- Figure 16 similar to the previous figure 15 illustrates for support 970 a possibility of assembling the annular sections by mechanical embedding.
- the two parts 971 and 972 of the connecting walls end in the form of a dovetail and are made to cooperate together. In this example, the two outer annular sections have no mechanical anchoring.
- FIG. 17 illustrates a similar figure of the support 980, seen in partial perspective, in which the apex 983 has been represented.
- This vertex 983 is not circumferentially continuous but is axially so.
- Such a discontinuous vertex which must however keep a small distance between two successive patterns has the advantage of greatly reducing the bending stiffness of the support. Its operation in run-flat can however be satisfactory if the different patterns of the crown can rest on each other when passing through the contact area.
- the circumferentially adjacent walls of the vertex are separated by a distance of less than a few millimeters, two for example.
- FIG. 18 shows, in partial side view, an annular section 65 comprising, an apex 66, a base 67 and, like the annular sections 60 and 70 of FIGS. 10 and 11, partitions 68 constituting support elements in the form of circumferential veil.
- the connecting walls 69 of this annular section have a double orientation.
- the connecting walls 691 extend radially between the base 67 and the top 66 and the connecting walls 692 extend circumferentially.
- the walls 691 do not reach the apex in order to avoid creating singular points which could damage the inner wall of the tire when running flat.
- the presence of the walls 692 appreciably increases the robustness of the connections between the annular sections.
- the annular sections may not be molded in a single operation but by assembling segments 9, four in the example presented. This assembly can be carried out by any known means, in particular bonding, welding or mechanical clipping. Preferably in this case, these segments 9 will comprise an apex and an annular body. It is then possible after assembling the annular sections and assembling the annular sections together to give a support part. overmolding a circumferential base on this support portion to give the final support comprising its means of resistance to centrifugation.
- annular segments or slices with a base not comprising means of resistance to centrifugation and subsequently add them, for example by winding or gluing.
- the assembly of the circumferential slices can be carried out in various known ways on a material of the thermoplastic elastomer type which will be the one that will be preferred.
- the assembly will be carried out by a process called “mirror welding", according to which one heats, substantially to the point of softening, two faces to be assembled by a heating plate disposed between said two faces, after which the plate is removed and the two faces are pressed against each other.
- mirror welding a process called "mirror welding”
- Such a method allows welding by surfaces, or weak surfaces, or precise welding points.
- obtaining the temperature of the softening point of the material can be obtained by friction in rotation of the annular sections against one another.
- the invention also relates to the supports manufactured by the method according to the invention. These supports being of a geometry unknown in the prior art, the invention also covers these supports as new industrial products.
