    “NON-PNEUMATIC WHEEL, STRUCTURALLY SUPPORTED, WITH CONTINUOUS LOOP REINFORCEMENT SET”
    CLAIMED PRIORITY [0001] This application claims the priority benefit of US Patent Application No. 12 / 661,196, filed on March 12, 2010 and US Provisional Patent Application No. 61 / 428,074, filed on December 29, 2010, which are incorporated into this document by reference for all purposes.
    FIELD OF THE INVENTION [0002] The present invention relates to a non-pneumatic wheel. More particularly, the present invention relates to the non-pneumatic wheel having a continuous loop reinforcement assembly that can support a load and has performance similar to pneumatic tires.
    BACKGROUND OF THE INVENTION [0003] The pneumatic tire is a known solution for conformity, comfort, mass and resistance to rotation; however, the pneumatic tire has disadvantages in terms of complexity, need for maintenance and susceptibility to damage. A device that improves the performance of the pneumatic tire could, for example, provide more compliance, better stiffness control, reduce maintenance requirements and damage resistance.
    [0004] Conventional solid tires, spring tires and shock absorber tires, although without the need for maintenance and susceptibility to tire damage, unfortunately their performance advantages are lacking. In particular, conventional and shock absorber tires usually include a solid rim, surrounded by a layer of resilient material. These tires have compression of the portion coming into contact with the floor of the resilient layer directly under the load to support the load. These types of tires can be heavy and rigid and do not have the capacity to absorb pneumatic tires.
    [0005] Spring tires usually have a ring of wood, metal or rigid plastic, with springs or spring as elements connecting it to an axle. Although the shaft is thus suspended by springs, the inflexible ring has only one
    Petition 870190128240, of 05/12/2019, p. 11/41
    2/27 small area of contact with the road, which offers essentially no conformity, and provides little traction and steering control.
    [0006] Consequently, a non-pneumatic wheel with performance characteristics similar to the pneumatic wheel would be useful. More particularly, a non-pneumatic wheel that does not require air pressure to provide performance characteristics of a pneumatic tire would be beneficial. Such a non-pneumatic wheel that can be built with an axle or connected to an axle for mounting on a vehicle or other transport device would also be very useful.
    SUMMARY OF THE INVENTION [0007] Aspects and advantages of the invention will be partly contained in the following description, or they may be obvious from the description or they can be learned through the practice of the invention.
    [0008] In an exemplary embodiment, the present invention provides a non-pneumatic wheel that defines radial, circumferential and transverse directions. The wheel includes an annular band that supports a portion of the tread coming into contact with the floor and extending over the circumferential direction. A continuous loop reinforcement assembly is positioned within the annular band. A mounting band is positioned radially within the annular band. A plurality of wheel spokes are connected to and extending radially between, the annular band and the mounting band.
    [0009] The continuous loop reinforcement assembly may include a first flexible cylindrical band and a second flexible cylindrical band positioned outside and radially outside the first flexible cylindrical band. One or both of the first flexible cylindrical band and the second flexible cylindrical band can include a coil that includes one or more materials wound on a propeller and at least one retainer connected to the coil and configured to maintain the integrity of the coil. One or more coil materials may include materials selected from the group comprising metal, steel, carbon, aramid and glass.

    3/27 higher melting temperature and lower melting temperature material can be configured in a core / shell arrangement. The at least one retainer may include one or more of the group comprising a monofilament yarn, multifilament yarns, and staple fiber yarns. The at least one retainer may include a chain reinforcement wire and a structural reinforcement wire having greater rigidity than the chain reinforcement wire. The current reinforcement wire may include a material with a lower melting temperature than the melting temperature of the structural reinforcement wires. The structural reinforcement wire may have a low shrinkage when heated to the lowest melting temperature of the current reinforcement wire. The current reinforcing wire may include a lower melting temperature polymer and a higher melting temperature polymer, wherein the higher melting temperature polymer shrinks when heated to the melting temperature of the melting temperature polymer. lower. The at least one retainer may include a plurality of reinforcement yarns intertwined in a coil in a leno weave with wire connections between one or more materials of the coil. The at least one retainer may include a plurality of reinforcement yarns tied to the bobbin in a Malimo-type knitted stitch pattern.
    [0011] The continuous loop reinforcement assembly may include a spacer positioned between the first flexible cylindrical band and the second flexible cylindrical band. The spacer can include a porous material, which can be, for example, a cross-linked foam. The annular band can include a matrix material that is received in the porous material of the spacer. The matrix material can comprise from, for example, a polyurethane.
    [0012] The continuous loop reinforcement assembly may include a plurality of spacers positioned between the first flexible cylindrical band and the second flexible cylindrical band. The continuous loop reinforcement assembly may include a plurality of flexible cylindrical bands that are spaced apart from one another along the radial direction.

Thus, it is intended that the present invention covers such modifications and variations as they come within the scope of the appended claims and their equivalents.
    Petition 870190128240, of 05/12/2019, p. 15/41
    6/27 [0029] Referring now to Figure 1, an exemplary embodiment of a continuous loop reinforcement assembly 10 of the present invention is shown. The continuous loop reinforcement assembly 10 provides reinforcement for a matrix material, such as epoxy, polyurethane or other elastomers. Assembly 10 can be incorporated into a non-pneumatic wheel to provide compatible structural reinforcement, as will be further described. The continuous loop reinforcement assembly 10 is porous for receiving the matrix material and being incorporated into the non-pneumatic wheel. The continuous loop reinforcement assembly 10 in the present invention is flexible in the radial direction to provide for the distribution of radial forces applied to the non-pneumatic wheel that is reinforced by the continuous loop reinforcement assembly 10. As used in this document, the reinforcement assembly continuous loop means the inclusion of one or more wires or cables that are wound on a propeller that includes at least three rotations. More specifically, the one or more wires or cables continue around it without using a seam across the band.
    [0030] As shown in figures 1 to 4 and 6, the continuous loop reinforcement assembly 10 includes a first flexible cylindrical reinforcement band 100, a second flexible cylindrical reinforcement band 300, and an intermediate resilient spacer 200 disposed between the first flexible cylindrical reinforcement band 100 and the second flexible cylindrical reinforcement band 300. The first flexible cylindrical reinforcement band 100 has a first inner surface band 101 and a first outer surface band 102. The second flexible cylindrical reinforcement band 300 has a second inner surface band 301 and a second outer surface band 302. The intermediate resilient spacer 200 (figure 6) has an inner surface of spacer 201 that surrounds the first outer surface band 102 and an outer surface of spacer 202 that surrounds the second inner surface band 301.
    [0031] The first flexible cylindrical band 100 (figure 2) is a cylindrical element with flexibility in the radial direction. In a typical embodiment, the first flexible cylindrical band 100 has a flexibility in which the first flexible cylindrical band 100 can be subjected to a radius of curvature that is one tenth or less
    Petition 870190128240, of 05/12/2019, p. 16/41
    7/27 of its normal internal diameter in the continuous loop reinforcement assembly 10 without experiencing a permanent configuration for the material. Because the first flexible cylindrical band 100 is a reinforcement component of the continuous loop reinforcement assembly 10, the Young's modulus of the material in the first flexible cylindrical band 100 along its tangential direction will be greater than the Young modulus of the reinforced matrix. by the first cylindrical band 100. In a predicted embodiment, the Young's modulus of the first flexible cylindrical band 100 is at least 1,000 times greater than the Young's modulus of the matrix reinforced by the first flexible cylindrical band 100.
    [0032] For the embodiment illustrated in figure 2, the first flexible cylindrical band 100 comprises a running band of a coil 110 (figures 3A and 3B), as a coil formed of one or more wires or cables 111 wound on a helix, each cable 111 making at least three loops around the first flexible cylindrical band 100. As used in this document, a running band is a band that continues around it without using a seam across the band. The 111 cables have high longitudinal traction and compression stiffness, and flexibility in the tangential direction. The materials used for cables 111 include high modulus materials, such as metal, steel, carbon, aramid or glass fibers.
    [0033] Several retainers 112 can be coupled to cable 111 to maintain the integrity of coil 110. Retainers 112 can be of a polymeric material interlaced with cables 111, a metal strip attached to cables 111, or the like. Retainers 112 provide axial stiffness for the first flexible cylindrical band 100 prior to incorporation of the matrix material with the continuous loop reinforcement assembly 10.
    [0034] Referring now to figures 3A and 3B, two modalities of the first flexible cylindrical band 100 are shown with retainers 112 comprising reinforcement wires 112a and 112b. Reinforcement threads 112a and 112b can be different ends of a single thread or two different threads. Reinforcement threads 112a and 112b are woven or sewn longitudinally on the coil 110 between the cables 111. Reinforcement threads 112a and 112b need to be flexible enough to incorporate the
    Petition 870190128240, of 05/12/2019, p. 17/41
    8/27 coil 110, but provide axial stiffness for the first flexible cylindrical reinforcement band 100.
    [0035] Still referring to figures 3A and 3B, in a standard embodiment at least one of the reinforcement threads 112a and 112b comprises polymeric thread with a material of higher melting temperature and a material of lower melting temperature. In a typical embodiment, both reinforcement yarns 112a and 112b comprise polymeric yarns with a higher melting temperature material and a lower melting temperature material. Before any melting connection of the two melting temperature materials, reinforcement wires 112a and 112b are incorporated into coil 110. Thus, reinforcement wires 112a and 112b are flexible enough to be incorporated into coil 110 with minimal difficulty. . After the reinforcement threads are incorporated into the coil 110, the subset is subjected to a temperature above the melting temperature of the lowest melting temperature material, and below the melting temperature of the highest melting temperature material. After the lower melting temperature material is melted, the temperature is reduced below its melting temperature, melting bond from the lower melting temperature material to the higher melting temperature material, thus creating a spacing wire of cast reinforcement. By merging the reinforcement threads 112a and 112b, the retainer 112 formed by threads becomes more rigid. This extra stiffness provides the first flexible cylindrical band with greater axial stiffness. In order to help maintain the axial stability of the first flexible cylindrical reinforcement strip 100 through the process of incorporating the matrix with the continuous loop reinforcement assembly 10, it is preferable that the lower temperature material of the reinforcement wires have a melting temperature above the matrix formation or curing temperature.
    [0036] Referring further to Figures 3A and 3B, reinforcement threads 112a and 112b using different melting temperature materials can be formed from one fiber or fibers, the materials having different melting points, such as core fibers / wrapper, or can be formed from a combination of fibers with different melting points. Reinforcement wires 112a and 112b can be
    Petition 870190128240, of 05/12/2019, p. 18/41
    9/27 monofilament, multifilament yarns, or continuous fiber yarns. When selecting reinforcement yarn strands 112a and 112b, care should be taken to select the strands that will withstand the frictional forces of the assembly and any processing of the continuous loop reinforcement assembly 10 prior to incorporation with the matrix, such washing. It is preferable that the higher melting temperature material of such reinforcement wires is selected to have sufficient elasticity to reduce the likelihood of assembly problems. It is also preferable that the highest temperature material of such reinforcement threads is selected to have low shrinkage characteristics, particularly when subjected to the heat of melting the reinforcement threads and incorporating the matrix material into the continuous loop reinforcement assembly. In one embodiment, the filament or fibers are a core and shell configuration with the highest melting temperature polymer, the core and polymer having the lowest melting temperature, being the shell. In another embodiment, the yarn comprises filaments or fibers of the polymer of the highest melting temperature and filaments or fibers separated from the polymer of the lowest melting temperature.
    [0037] Still referring to figures 3A and 3B, the reinforcement wire 112a is illustrated as a structural wire, and the reinforcement wire 112b is illustrated as a chain wire. The structural reinforcement wire is stiffer and heavier than the current reinforcement wire 112b. Structural reinforcement wire 112a provides axial rigidity of coil 110. Reinforcement wire 112a can be protected from the outside or inside of coil 110. In one embodiment, structural reinforcement wire 112a is a monofilament yarn. Chain reinforcement wire 112b protects cables 111 from the adjacent coil to structural reinforcement wire 112a. In one embodiment, the current reinforcing wire 112b includes a lower melting temperature polymer material as described above and can include a higher melting temperature material as described above. The melting temperature of the lower melting temperature polymer material in the chain wire is a lower temperature than the melting temperature of the main materials in the structural reinforcement wire 112a. In this way, the current reinforcement wire 112b can be used to better protect the cables 111 from the coil 110 to the structural reinforcement wire.
    Petition 870190128240, of 05/12/2019, p. 19/41
    10/27 [0038] When using a current reinforcement wire 112b having a polymer with a lower melting temperature, it is preferable that structural reinforcement wire 112a has low shrinkage when subjected to the melting temperature of the melting temperature polymer lower in the current reinforcement yarn 112b, such as with a thermosetting polymer yarn. In one embodiment, the current reinforcing yarn 112b includes filaments or staple fibers with a lower melting temperature and filaments or staple fibers with a higher melting temperature. When the current reinforcement yarn 112b includes filaments or staple fibers of both the lower melting temperature polymer and the higher melting temperature polymer, the filament with the higher melting temperature polymer has some contraction during the melting the polymer of the lower melting temperature, such as with a wire that is not thermoset, thus approaching the connection between the structural reinforcement wire 112a and the at least one cable 111 of the coil 110.
    [0039] Referring further to figures 3A and 3B, two different patterns are shown for reinforcement wires 112a and 112b. In figure 3A, the reinforcement threads 112a and 112b protect the cables 111 of the coil 110 with a weave pattern. As shown in figure 3A, the reinforcement threads 112a and 112b are interwoven into the coil 110 in a smooth weave, with wire connections occurring between the cables. However, reinforcement yarns 112a and 112b could be incorporated into the bobbin 110 with other weave patterns. In figure 3B, the reinforcement yarns 112a and 112b protect the cables 111 from the coil 110 with a knitted stitch pattern of the Malimo type. However, reinforcement threads 112a and 112b could be incorporated into the bobbin 110 with other sewing patterns. Although figures 3A and 3B illustrate reinforcement yarns 112a and 112b as being incorporated into the coil 110, with a weave or stitch pattern, a series of simple reinforcement yarns 112 could also be wound across the entire coil 110.
    [0040] Referring now to figure 4, the second flexible cylindrical band 300 is a cylindrical element with flexibility in the radial direction. In a modality, the second flexible cylindrical band 300 has a flexibility in which the second
    Petition 870190128240, of 05/12/2019, p. 20/41
    11/27 flexible cylindrical band 300 can be subjected to a radius of curvature that is one tenth or less of its normal internal diameter in the continuous loop reinforcement assembly 10 without experiencing a permanent configuration for the material. Because the second flexible cylindrical band 300 is a component of the continuous loop reinforcement assembly 10, the Young's modulus of the material of the second flexible cylindrical band 300 in the tangential direction will be greater than the Young modulus of the matrix reinforced by the second flexible cylindrical band 300. In a modality, the Young's modulus of the second flexible cylindrical band 300 is at least 1,000 times greater than the Young's modulus of the matrix reinforced by the second flexible cylindrical band 300.
    [0041] In the embodiment illustrated in figure 4, the second flexible cylindrical band 300 comprises a running band of a coil 310, such as a coil formed of one or more cables 311 wound on a helix, each cable 311 making at least three turns in around the second flexible cylindrical band 300. The cables 311 have high longitudinal traction and compression stiffness, and flexibility in the tangential direction. Standard materials for 311 cables include high modulus materials, such as metal, steel, carbon, aramid or glass fibers. Several retainers 312 can be attached to cable 311 to maintain the integrity of coil 310. Retainers 312 may be of a polymeric material interlaced with cables 311, a metal strip attached to cables 311, or the like. Retainers 312 provide axial stiffness to the second flexible cylindrical band 300 prior to incorporation of the matrix material with the continuous loop reinforcement assembly 10.
    [0042] Referring now to Figures 5A and 5B, two modalities of the second flexible cylindrical band 300 with retainers 312 are shown with reinforcement wires 312a and 312b. Reinforcement threads 312a and 312b can be different ends of a single thread or two different threads. Reinforcement wires 312a and 312b are longitudinally woven into coil 310 between cables 311. Reinforcement wires 312a and 312b need to be flexible enough to be incorporated into coil 310, but provide axial stiffness for the second flexible cylindrical band 300.
    Petition 870190128240, of 05/12/2019, p. 21/41
    12/27 [0043] Still referring to figures 5A and 5B, in a modality shown at least one of the reinforcement threads 312a and 312b comprise polymeric threads with a higher melting temperature material and a higher melting temperature material low. In a typical embodiment, both reinforcement yarns 312a and 312b comprise polymeric yarns with a higher melting temperature material and a lower melting temperature material. Prior to any melting connection of the two melting temperature materials, reinforcement yarns 312a and 312b are incorporated into coil 310. Thus, wires 312a and 312b are flexible enough to be incorporated into coil 310 with minimal difficulty. After the reinforcement threads are incorporated into the coil 310, the subset is subjected to a temperature above the melting temperature of the lowest melting temperature material, and below the melting temperature of the highest melting temperature material. After the lower melting temperature material is melted, the temperature is reduced below its melting temperature, melting bond from the lower melting temperature material to the higher melting temperature material, thus creating a spacing wire of cast reinforcement. By fusing the reinforcement wires 312a and 312b, the retainer 312 formed by wires becomes more rigid. This extra stiffness provides the first flexible cylindrical band with greater axial stiffness. In order to help maintain the axial stability of the second flexible cylindrical reinforcement band 300 through the process of incorporating the matrix with the continuous loop reinforcement assembly 10, it is preferable that the lower melting temperature material of the reinforcement wires has a melting temperature above the formation or curing temperature of the matrix.
    [0044] Referring further to figures 5B and 5A, reinforcement yarns 312a and 312b using different melting temperature materials can be formed of one fiber or fibers, the materials having different melting points, such as core fibers / wrapper, or can be formed from a combination of fibers with different melting points. Reinforcement yarns 312a and 312b can be monofilament yarns, multifilament yarns, or discontinuous yarns. When selecting wire reinforcement wires 312a and 312b, care should be taken to select the wires that
    Petition 870190128240, of 05/12/2019, p. 22/41
    13/27 will withstand the frictional forces of the assembly and any processing of the continuous loop reinforcement assembly 10 prior to incorporation with the matrix, such as washing. It is preferable that the higher melting temperature material of such reinforcement wires be selected to have sufficient elasticity to reduce the likelihood of assembly problems. It is also preferred that the higher melting temperature material of such reinforcement threads be selected to have low shrinkage characteristics, particularly when subjected to the heat of melting the reinforcement threads and incorporating the matrix material into the loop reinforcement assembly. continuous. In one embodiment the filament or fibers are a core and shell configuration with the highest melting temperature polymer, the core and polymer being the lowest melting temperature, the shell being. In another embodiment, the yarn comprises filaments or fibers of the higher melting temperature polymer and separate filaments or fibers.
    [0045] Still referring to figures 5A and 5B, reinforcement wire 312a is illustrated as a structural wire and reinforcement wire 312b is illustrated as a chain wire. Structural reinforcement wire 312a is stiffer and heavier than chain reinforcement wire 312b. Structural reinforcement wire 312a provides axial rigidity of coil 310. Reinforcement wire 312a can be protected from the outside or inside of coil 310. In one embodiment, structural reinforcement wire 312a is a monofilament yarn. Chain reinforcement wire 312b protects the coil cables 311 adjacent to structural reinforcement wire 312a. In one embodiment, the current reinforcing wire 312b includes a lower melting temperature polymer material as described above, and may include a higher temperature polymer material as described above. The melting temperature of the lower melting temperature polymer material in the chain wire is a lower temperature than the main materials in the structural reinforcement wire 312a. In this way, reinforcement wire 312b can be used to better protect cables 311 from coil 310 to the structural reinforcement wire.
    [0046] When using a current reinforcement wire 312b having a polymer with a lower melting temperature, it is preferable that the reinforcement wire
    Petition 870190128240, of 05/12/2019, p. 23/41
    Structural 14/27 312a has low shrinkage when subjected to the melting temperature of the lower melting temperature polymer in the current reinforcement yarn 312b, such as with a thermosetting polymer yarn. In one embodiment, the current reinforcing yarn 312b includes filaments or staple fibers with a lower melting temperature and filaments or fibers with a higher melting temperature. When the current reinforcing yarn 312b includes filaments or staple fibers of both the lower melting temperature polymer and the higher melting temperature polymer, it is also said that the higher melting temperature polymer filament has some contraction during the melting of the lower melting temperature polymer, such as with a wire that is thermoset, thus approaching the connection between structural reinforcement wire 312a and at least one cable 311 from coil 310.
    [0047] Referring further to figures 5B and 5A, two different patterns are shown for reinforcement wires 312a and 312b. In figure 5A, the reinforcement threads 312a and 312b protect the cables 311 from the coil 310 with a weave pattern. As shown in figure 5A, the reinforcement wires 312a and 312b are interwoven into the coil 310 in a leno weave, with wire connections occurring between the cables. However, reinforcement yarns 312a and 312b could be incorporated into the bobbin 310 with other weave patterns. In figure 5B, the reinforcement yarns 312a and 312b protect the cables 311 from the coil 310 with a Malimo type knitted stitch pattern. However, reinforcement threads 312a and 312b could be incorporated into bobbin 310 with other sewing patterns. Although figures 5B and 5A illustrate reinforcement yarns 312a and 312b as being incorporated into the bobbin 310, with a weave or stitch pattern, a series of simple reinforcement yarns 312 could also be wound across the entire bobbin 310.
    [0048] Referring now to Figures 1 to 6, the intermediate resilient spacer 200 is a resistant material that applies constant pressure to the first outer surface band 102 and the second inner surface band 301. What is meant by resilient is that the flexible spacer generates increasing reaction force with an increasing amount of compression. The thickness of the resilient spacer
    Petition 870190128240, of 05/12/2019, p. 24/41
    15/27 intermediate 200 in the radial direction is larger than the space created between the first flexible cylindrical reinforcement band 100 and the second flexible cylindrical reinforcement band 300 in the radial direction. In this way, the intermediate resilient spacer 200 exerts constant pressure between the two flexible cylindrical reinforcement bands 100, 300, around the continuous loop reinforcement assembly 10. To help create uniform pressure throughout the loop reinforcement assembly continuous 10, the intermediate resilient spacer 200 preferably has a substantially uniform thickness and is substantially uniform in composition. This constant pressure maintains the spatial relationship between the first flexible cylindrical reinforcement band 100 and the second flexible cylindrical reinforcement band 300. The pressure between the first flexible cylindrical reinforcement band 100 and the second flexible cylindrical reinforcement band 300 creates a balance of force that will maintain the centering of the two bands, even if there are variations in the diameter of the first or second flexible cylindrical bands 100, 300. When designing the intermediate resilient spacer 200, care must be taken to avoid excessive pressure on the first flexible cylindrical reinforcement band 100. When the intermediate resilient spacer 200 exerts excessive pressure on the first flexible cylindrical reinforcement band 100, the first flexible cylindrical reinforcement band 100 will tend to deform the shape. In one embodiment, the intermediate resilient spacer 200 can resiliently recover from at least 30% compression. In another embodiment, the materials forming the intermediate resilient spacer 200 elastically can recover more than 80% compression.
    [0049] Preferably, the intermediate resilient spacer 200 remains and the two reinforcement bands 100, 300, in place without additional fastening. Normally, the normal pressure and resulting friction between the intermediate resilient spacer 200 and the two reinforcement bands 100, 300, are sufficient to stabilize the continuous loop reinforcement assembly 10, even during the incorporation of the matrix material when forming a cylindrical element. . When the intermediate resilient spacer 200 exerts pressure between the two flexible cylindrical reinforcement bands 100, 300, it also creates a protrusion of the spacer material
    Petition 870190128240, of 05/12/2019, p. 25/41
    16/27 between cables 111, 311. This protrusion between cables 111, 311, results in further stabilization of the continuous loop reinforcement assembly 10 and helps to stabilize the position of individual cables 111, 311, within the cylindrical reinforcement bands flexible 100, 300, respectively. In other embodiments, the intermediate resilient spacer 200 can use a material with very small protrusions or arms that hold cables 111, 311, thereby stabilizing the position of individual cables 111, 311, within cylindrical reinforcement bands 100, 300, respectively . The stabilization of the reinforcement bands 100, 300, and the intermediate resilient spacer 200 can be enhanced with material and adhesive geometry that provides an adhesion effect between the intermediate resilient spacer 200 and flexible cylindrical reinforcement bands 100, 300. Friction, adhesion , or improved adhesion between the intermediate resilient spacer 200 and the first flexible cylindrical reinforcement band 100 will also increase the pressure that can be exerted by the intermediate resilient spacer 200 on the first flexible cylindrical reinforcement band 100 before the buckling of the first reinforcement band begins. flexible cylindrical 100.
    [0050] In addition to providing a spring as a constant pressure between the two reinforcement bands 200, 300, the intermediate resilient spacer 200 is also porous to receive the matrix material that is reinforced. Preferably, the intermediate resilient spacer 200 is porous without closed cavities or tortuous flow paths that reverse the flow direction or create dead end flows. A porous material will include empty spaces, reducing the volume of the mass that make up the porous material. It is preferable to increase the empty area in a porous material, reducing the volume of the mass of a porous material to the minimum practical amount. For example, the volume of the mass forming the porous material can have a maximum volume of forty percent (40%). Alternatively, the volume of the mass forming the porous material can have a maximum volume of fifteen percent (15%). In a typical modality, the volume of the mass forming the porous material has a maximum volume of five percent (5%). In addition, in an optional mode, the intermediate resilient spacer 200
    Petition 870190128240, of 05/12/2019, p. 26/41
    17/27 comprises the same material as in the matrix, such as polyurethane.
    [0051] In a standard embodiment of the present invention, the intermediate resilient spacer 200 is a flexible member. Flexing the intermediate resilient spacer 200 facilitates the assembly of the continuous loop reinforcement assembly 10, and allows the final reinforced matrix element to flex without functional damage to the components of the continuous loop reinforcement assembly 10 or matrix. Similar to the first flexible cylindrical reinforcement band 100 and the second flexible cylindrical reinforcement band 300 it is preferable that the intermediate resilient spacer 200 has a flexibility in which the resilient spacer intermediate 200 can be subjected to a radius of curvature that is one tenth or less of its normal internal diameter in the continuous loop reinforcement assembly 10 without experiencing a permanent configuration for the material. In another modality, the intermediate spacer 200 has greater flexibility than the cylindrical reinforcement bands it engages with.
    [0052] In one embodiment, the intermediate resilient spacer 200 can be a strip of material that is cut to the desired length, width and thickness and then inserted between the first reinforcement band 100 and the second reinforcement band 300. In one embodiment, the ends of the strip of material are connected to form the intermediate resilient spacer 200. In another embodiment, the strip of material placed between the first reinforcement band 100 and the second reinforcement band 300 as the intermediate resilient spacer 200, it is a strip of material that is not loosely connected at the ends with the ends adjacent to each other. In some cases, it may be acceptable to have a small space between the ends of a material, forming the intermediate resilient spacer 200. In addition, the axial width of the intermediate resilient spacer 200 does not always need to be equal to the entire width of the reinforcement bands 100 or 300.
    [0053] In one embodiment, the intermediate resilient spacer 200 is a foam material. In order to provide a spacer with porous characteristics, the foam material can be an open cell foam material. In particular,
    Petition 870190128240, of 05/12/2019, p. 27/41
    18/27 a cross-linked foam material provides a porous and resistant material for the intermediate resilient spacer 200. In the cross-linked foam, cell walls are removed by methods such as passing a controlled flame or chemical fluid through the medium. The remainder of the crosslinked foam material can also provide arms that protect the cables 111, 311, within the cylindrical reinforcement bands 100, 300. In addition, the foam material may be the same material as the matrix to be reinforced. For example, polyurethane foam can be used as the intermediate resilient spacer 200 in a cylindrical reinforcement element 10 to reinforce a polyurethane matrix.
    [0054] In yet another embodiment, the intermediate resilient spacer 200 is a non-woven material. One type of non-woven material that could be used as the spacer is a non-woven material with thick filaments that are formed in a three-dimensional shape, such as a two-dimensional or three-dimensional wavy configuration. Nonwovens with thick oriented fibers, or z-oriented, can provide resilient properties for the nonwoven.
    [0055] In yet another embodiment, the intermediate resilient spacer 200 is a fabric of the spacer. A spacer fabric is a sewing or weaving fabric that has two layers of face, separated by fibers or threads, extending between the two layers. The fibers between the two layers provide a spring-like force that is opposite to the compression of the spacer fabric. Considerations about the fabric would be opening, pore shape, pore size, stiffness, direction of separation of fibers or threads, material's ability to adhere to the matrix material, and the like.
    [0056] Referring now to figure 7, an embodiment of the present invention is shown with the intermediate resilient spacer 200, having a width less than the width of the first cylindrical reinforcement band 100 or the second cylindrical reinforcement band 300. Na In this embodiment, the intermediate resilient spacer 200 is centered towards the width of the continuous loop reinforcement assembly 10. The flexible cylindrical reinforcement bands 100, 300, are designed to maintain a constant spatial relationship with each other in widths beyond the resilient spacer
    Petition 870190128240, of 05/12/2019, p. 28/41
    19/27 intermediate 200.
    [0057] Referring now to figure 8, an embodiment of the present invention is shown with the first flexible cylindrical reinforcement band 100 and the second flexible cylindrical reinforcement band 300 being spaced by two intermediate resilient spacers 200a, 200b. In this embodiment, the intermediate resilient spacers 200a and 200b are narrower than the flexible cylindrical reinforcement bands 100, 300 and are arranged opposite the outer edges of the flexible cylindrical reinforcement bands 100, 300. Dividing the intermediate resilient spacer in two bands arranged on the outer edges of the flexible cylindrical reinforcement elements 100, 300, the continuous loop reinforcement assembly 10 will have better resistance to escape from flat rotational disturbances.
    [0058] Referring now to figure 9, an embodiment of the present invention is shown, in which a third flexible cylindrical reinforcement band 500 is disposed outside the second flexible cylindrical reinforcement band 300 and a second intermediate resilient spacer 400 is arranged between the second flexible cylindrical reinforcement band 300 and the third cylindrical reinforcement band 500. The third flexible cylindrical reinforcement band 500 has the same properties and characteristics as the first flexible cylindrical reinforcement band 100 or the second flexible reinforcement band 300. O second intermediate resilient spacer 400 also has the same properties and characteristics as the intermediate resilient spacer 200. It is envisaged that the cylindrical reinforcement assembly of the present invention could have several layers of cylindrical reinforcement bands separated by one or more resilient, intermediate layers.
    [0059] In another exemplary embodiment, it should be understood that the continuous loop reinforcement assembly can be manufactured without a resilient spacer as well. More specifically, referring to figure 1, the continuous loop reinforcement assembly 10 can be created without a resilient spacer 200. In this case, care must be taken to maintain the proper spacing of the reinforcement bands 100 and 300, as a set of fabrication 10. For example, between the adequately spaced reinforcement bands 100 and 300, a material could be dripped or watered so as not to disturb
    Petition 870190128240, of 05/12/2019, p. 29/41
    20/27 said spacing. This material must have a relatively high viscosity and must solidify while touching reinforcement bands 100 and 300 in order to maintain adequate spacing. Preferably, this material will also have a higher melting temperature than the material used to build reinforcement bands 100 and 300. Also, other methods can be used to manufacture a continuous loop reinforcement assembly without a resilient spacer. [0060] Figure 10 provides a perspective view of an exemplary embodiment of a structurally supported wheel 401 in accordance with the present invention. As used in this document, structurally supported means that the tire exerts a load on its structural components without the support of the gas inflation pressure. Figure 11 provides a partial, cross-sectional view of wheel 401 taken along line 11-11, as shown in figure 10. Arrow C indicates circumferential direction. The arrow R indicates the radial direction. Arrows A denote the axial direction, also sometimes referred to as the transverse or lateral direction. [0061] Referring now more particularly to figure 11, the continuous loop reinforcement assembly 10 is positioned within a band 405 extending over the circumferential direction C. For this exemplary embodiment, the assembly 10 includes the first flexible cylindrical band 100 and the second flexible cylindrical band 300 separated by the resilient spacer 200 as previously described. The bands 100 and 300, for example, provide the vertical stiffness for wheel 401 while the resilient spacer 200 assists in providing a shear layer for wheel 401 as will be further described.
    [0062] According to the invention, the 401 wheel is useful in applications where the traction, steering or suspension qualities of a pneumatic tire are advantageous or in need of improvement. A structurally supported wheel 401 constructed in accordance with the present invention, as described below, can offer greater conformity and rigidity characteristics, on a wheel that requires less maintenance than a pneumatic tire. In addition to the use of motor vehicles, such a wheel could also be advantageously used, for example, in a wheelchair, a stretcher, a hospital bed, a trolley for
    Petition 870190128240, of 05/12/2019, p. 30/41
    21/27 sensitive equipment, or other vehicles or means of transport where sensitivity to shock is important. In addition, the wheel can be used in place of casters for chairs or other furniture, or as wheels for baby strollers, skateboards, inline skates, etc. The 401 wheel of the invention could be used on machines or apparatus where the rolling load or applying wheel load is used. The term vehicle is used below for purposes of description; however, any device on which compatible wheels could be mounted is included in the following description and the vehicle must be understood to include the same.
    [0063] Wheel 401 as shown in figures 10 and 11 has an annular band 405 and a plurality of traction transmission elements, illustrated as wheel spokes 420, extending transversely through and into band 405, a band of mounting 425 at the radially internal spoke end of the wheel 420. The mounting strip 425 secures the wheel 401 to an axis 430. A portion of the tread 410 is formed at the end of the tread 405. The tread portion 410 may be an additional layer coupled to the band 405, for example, to provide different traction and use properties than the material used to build the band 405. Alternatively, the tread 410 may be formed as part of the outer surface of the compatible band, as shown in figure 10. Tread features can be formed in the tread portion 410 and can include blocks 415 and grooves 440.
    [0064] As mentioned, wheel spokes 420 in the exemplary embodiment of figures 10 and 11 extend transversely across the entire wheel 401, which as used herein means that the wheel spokes 420 extend to both sides of the wheel 401 and they can be aligned with the axis of rotation, or they can be oblique to the axis of the wheel. In addition, extending inward means that the wheel spokes 420 extend between the band 405 and mounting band 425 and may be in a plane radial to the wheel axis or may be oblique to the radial plane. In addition, as shown in Figure 10, wheel spokes 420 may actually include spokes at angles other than the radial plane. Various shapes and patterns can be used as shown, for example, in U.S. Patent No.
    Petition 870190128240, of 05/12/2019, p. 31/41
    22/27
    7,013,939.
    [0065] Band 405 supports the load on wheel 401 and deforms resiliently according to the road (or other support surface) to provide traction and handling of resources. More particularly, as described in US Patent No. 7,013,939, when a load is placed on the wheel 401 through the axis 430, the band 405 acts in a compatible manner where it tilts and otherwise deforms to contact the ground and forms a contact section, which is the portion of wheel 401 that is in contact with the ground under such load. The portion of the band 405 that is no longer in contact with the floor acts similar to an arc and provides a circumferential compression stiffness and a longitudinal flexing stiffness in the equatorial plane high enough to act as a load-bearing element. As used in this document, the equatorial plane, a plane that passes perpendicular to the axis of rotation of the wheel and cuts through the structure of the wheel.
    [0066] The load on the wheel 401, transmitted from the vehicle (not shown) to the axis 430 essentially locks by wheel spokes 420 coupled to the portion that supports the load of the band 405. Wheel spokes 420 in the region in contact with the ground do not experience the traction load due to the load. When the wheel 401 turns, of course, the specific part of the compatible band 405 acting as an arc changes continuously, however, the concept of an arc is useful for understanding the load-bearing mechanism. The number of slopes of the 405 band and, consequently, the length of the contact section is proportional to the load. The ability of the 405 band to tilt resiliently under the load provides a compatible ground contact area that acts similarly to a pneumatic tire, with similar advantageous results.
    [0067] For example, band 405 can involve obstacles to provide a smoother path. In addition, the 405 band is capable of transmitting forces to the ground or road for traction, turns and steering. On the other hand, in typical cushioning and solid tires, the load is supported by compressing the tire structure in the contact area, which includes the compaction of the cushioning material
    Petition 870190128240, of 05/12/2019, p. 32/41
    23/27 under the rigid axis. The tendency of the damping material is limited by the material's compaction properties and the thickness of the material on the rigid wheel or axle.
    [0068] Still referring to figures 10 and 11, wheel spokes 420 are substantially plate-like elements of length L in the radial direction, width W in the axial direction generally corresponding to the axial width of the compatible band 405, although other widths W can be used including widths W that vary along the radial direction, as shown in figure 11. Wheel spokes 420 also have a thickness (ie a dimension perpendicular to length L and width W) that is generally much less than any length L or width W, which allows a wheel axle to be deformed or tilted when under compression. Diluent wheel spokes will tilt when passing through the contact area with substantially uncompressed strength, ie, providing no or only negligible load compression force. When the radius thickness 420 is increased, the wheel spokes can provide some rolling force of the compressive load in the area in contact with the ground. The predominant load, transmitting the action of 420 wheel spokes as a whole, however, is in traction. The thickness of the wheel axles in particular can be selected for specific vehicle or order requirements.
    [0069] As seen in figure 11, preferably wheel spokes 420 are directed in relation to the compatible band 405 in the axial direction A. The tension in the wheel spokes 420 is therefore distributed in the band 405 to support the load. As an example, the wheel spokes 420 can be formed of an elastomeric material, having a tensile modulus of about 10 to 100 MPa. The wheel spokes 420 can be reinforced if desired. The material used to construct the wheel spoke material 420 must also exhibit elastic behavior to return to the original length after being stretched to, for example, 30%, and exhibit constant traction when the wheel spoke material is tensioned to, for example, example, 4%. In addition, it is desirable to have a material with a δ tangent of not more than 0.1 under the relevant operating conditions. For example,
    Petition 870190128240, of 05/12/2019, p. 33/41
    24/27 commercially available rubber or polyurethane can be identified for meeting these requirements. In another additional example, urethane brand Vibratano B836 from Chemtura Corporation of Middlebury, Conn. has been suitable for construction of 420 wheel spokes.
    [0070] For the exemplary embodiment of figures 10 and 11, the wheel spokes 420 are interconnected by the inner radial assembly band 425, which surrounds the axis 430 to assemble the wheel 401 to the axis 430. Depending on the construction materials and process the shaft 430, the mounting band 425, the ring band 405 and wheel spokes 420 can be molded as a single unit. Alternatively, one or more of these components can be formed separately and then connected to each other via, for example, adhesives or molding. In addition, other components can be included as well. For example, an interface band could be used to connect the spoke spokes 420 at its ends radially, and then the interface band would be coupled to the band 405.
    [0071] According to a new modality, wheel spokes 420 could be mechanically connected to the axle 430, for example, by providing an enlarged portion on the inside of each wheel axle 420 that involves a groove device on the axis 430, or by coupling adjacent wheel spokes 420 to form a loop on a hook or a bar formed on the axis 430.
    [0072] Substantially pure traction load support is obtained by having a wheel radius 420 that has high stiffness effective in tension, but very low stiffness in compression. To facilitate tilting in a specific direction, wheel spokes 420 can be curved. Alternatively, the wheel spokes 420 can be shaped with a curvature and straightened by thermal contraction during cooling to provide a predisposition to bending in a given direction.
    [0073] Wheel spokes 420 must withstand torsion between ring band 405 and axle 430, for example, when torque is applied to wheel 401. In addition, wheel spokes 420 must withstand lateral deflection when, for example, they turn or make curves.
    Petition 870190128240, of 05/12/2019, p. 34/41
    25/27
    As will be understood, the wheel spokes 420 which are in the axial-radial plane, that is, are aligned with both radial and axial directions, have high resistance to axially directed forces, but, particularly if elongated in the radial direction R, can have relatively low torque resistance in the circumferential direction C. For certain vehicles and applications, for example, which produce relatively low torque, a wheel spoke package having relatively short radii 420 aligned with the radial direction R will be suitable. For applications where high torque is expected, one of the arrangements, as shown in figures 5 to 8 of U.S. Patent 7,013,939, may be additionally suitable. In the variations shown in this document, wheel spoke arrangements are provided that include a component of resistance to radial force and circumferential directions, thus adding torque resistance, while maintaining components of resistance to radial and lateral forces. The orientation angle can be selected depending on the number of used wheel spokes and the spacing between adjacent wheel spokes. Other alternative arrangements can also be used.
    [0074] An advantage of the compatible wheel of the invention is that the selection of the size and arrangement of the band 405 and wheel spokes 420 allow the vertical and lateral torsional rigidity of the wheel to be adjusted independently of the contact pressure and each other. The parameters of operation of the 405 band, transport and load tendency, are determined in part by the selection of materials with the circumferential and longitudinal compression stiffness of bending stiffness in the equatorial plane to satisfy the load requirements of the project. These parameters are analyzed taking into account the wheel diameter 401, annular bandwidth 405 in the axial direction A, thickness of the band 405 in the radial direction R, and the length and spacing of the wheel spokes 420. The number of wheel spokes is selected to maintain the circularity of the band 405, and will also depend on the spacing between the adjacent wheel spokes 420.
    [0075] Continuing with figure 11, as indicated above, band 405 includes a continuous loop reinforcement assembly 10, which can, for example, be integrally molded as part of the non-pneumatic wheel 401 or constructed
    Petition 870190128240, of 05/12/2019, p. 35/41
    26/27 separately and then coupled with the other elements of wheel 401. Where resilient spacer 200 is porous, the matrix material used to construct the band 405 can also be used to impregnate spacer 200 by passing in and through its porous material. For example, the resilient spacer 200 can be constructed as an open cell foam, in which a polymer such as a polyurethane is received. A polyurethane suitable for such a construction includes, for example, Urethane brand Vibratano B836 from Chemtura Corporation of Middlebury, Conn.
    [0076] Figure 11 provides only an exemplary embodiment of a 405 band when it can be used with the present invention. For example, figure 12 provides another example of a band 405 when it can be used on wheels 401 (wheel spokes 420 are omitted by this cross-sectional view, as well as the views in figures 13 and 14). In this way, the continuous loop reinforcement assembly 10 of figure 7 is shown incorporated in the band 405. As shown, the resilient spacer 200 is narrower than the first flexible cylindrical band 100 or the second flexible cylindrical band 300. The spacer resilient 200 can be constructed as previously described.
    [0077] Figure 13 provides another example of a band 405 when it can be used on wheels 401, where band 405 includes the continuous loop reinforcement assembly 10 of figure 8. As shown, the resilient spacer 200 is constructed from of two intermediate resilient spacers 200a and 200b. A space 435 is shown between the spacers 200a and 200b. Space 435 can be opened or filled with matrix material. Resilient spacers 200a and 200b can be constructed as described previously for spacer 200.
    [0078] Figure 14 provides yet another example of a band 405 when it can be used on wheels 401, where band 405 includes the continuous loop reinforcement assembly 10 of figure 9. As shown, the resilient spacer 200 is constructed from from two resilient spacers, 200 and 400 and includes a third flexible cylindrical reinforcement band 500. Figure 14 is provided by way of example only, several additional spacers and flexible cylindrical bands can be
