Abstract

Anaxisymmetric reinforcing rings (AAR) are dimensioned to be at least partially embedded within an article wall (EMW) of an elastomeric article (ART). The anaxisymmetric reinforcing rings have an axis of revolution (AXR) and a path of revolution (PRV). The anaxisymmetric reinforcing rings include a ring wall that extends endlessly around the axis of revolution and include first and second cross-sectional profiles (PF1, PF2) taken normal to the path of revolution. The first and second cross-sectional profiles are spaced circumferentially apart, and the second cross-sectional profile has at least one of a different profile size, a different profile shape, and / or a different profile dimension relative to the first cross-sectional profile. Elastomeric articles including one or more anaxisymmetric reinforcing rings at least partially embedded within an elastomeric wall thereof are also included. In some cases, the elastomeric articles at least partially form gas spring assemblies (200). Suspension systems (500) including such gas spring assemblies are also included.

Description

ELASTOMERIC ARTICLES INCLUDING ANAXISYM METRIC REINFORCING RINGS AND ASSEMBLIES INCLUDING SAMEBACKGROUND

[0001] The subject matter of the present disclosure broadly relates to the art of anaxisymmetric reinforcing rings dimensioned to be at least partially embedded within elastomeric articles, such as pneumatic tires and flexible spring members of gas spring assemblies, for example. Elastomeric articles including one or more of such anaxisymmetric reinforcing rings as well as assemblies including such elastomeric articles are also included. In some cases, vehicle suspension systems including one or more gas spring assemblies including such elastomeric articles can also be included.

[0002] In some cases, the subject matter of the present disclosure may find particular application and use in conjunction with components for wheeled vehicles, and will be shown and described herein with reference thereto. However, it is to be appreciated that the subject matter of the present disclosure is also amenable to use in other applications and environments, and that the specific uses shown and described herein are merely exemplary. For example, the subject matter of the present disclosure could be used in connection with elastomeric articles and / or assemblies of non-wheeled vehicles, support structures, height adjusting systems and actuators associated with industrial machinery, components thereof and / or other such equipment. Accordingly, the subject matter of the present disclosure is not intended to be limited to use associated with vehicles and / or suspension systems thereof.

[0003] In some cases, it may desirable to reduce the overall weight of a vehicle and / or the suspension system thereof. Reducing the weight of various components of the one or more tires of the vehicle and / or one or more gas spring assemblies of a suspension system can be one contributing factor to achieving such a goal. Traditionally, reinforcing rings, or so-called “bead wires”, have been extensively used in connection with the construction of elastomeric articles, such as gas spring assemblies and pneumatic tires, for example. In such constructions, known reinforcing rings aid in establishing substantially inextensible mounting beads and / or providing internal support to crimped connections along mounting beads of gas spring assemblies, for example. In many cases, such so-called “bead wires” are either formed from lengths of solid rod that are configuredinto endless, annular rings or formed from an extremely long length of thin wire that is wound along and around itself into an endless annular ring. In many cases, such conventional “bead wires” are formed from metal material.

[0004] While such known reinforcing elements generally provide sufficient reinforcing strength to achieve the desired performance of such elastomeric articles, known reinforcing elements also contribute to the overall weight of vehicle and the individual components thereof. In some cases, reinforcing rings for elastomeric articles can be at least partially formed from non-metallic material. One such known construction is shown and described in U.S. Patent No. 9,381 ,783, which discloses a reinforcing device that can be embedded within a mounting bead of a flexible spring member and is formed from a flat profile strip of glass-fiber-reinforced plastic wound into a coil of mutually adjacent flat turns. Other such known constructions are shown and described in U.S. Patent No. 9.261 ,156, which discloses reinforcing devices that can be embedded within a mounting bead or girdle wall of flexible spring members and which are at least partially formed from a polymeric material. However, known reinforcing elements, including those at least partially formed from polymeric material, have generally axisymmetric configurations. As such, the outermost surface of such known reinforcing elements are substantially uniform in cross-sectional size, shape and configuration around the entire reinforcing element or at least the substantial entirety thereof.

[0005] Notwithstanding the widespread usage of known reinforcing ring constructions and the overall success of the wide variety of elastomeric articles that commonly include the same, it is believed desirable to overcome the foregoing and / or other disadvantages of known constructions while retaining comparable or improved performance, ease of manufacture, ease of assembly, ease of installation, reduced weight, and / or reduced cost of manufacture. Thus, it is believed to be generally desirable to develop new constructions and / or designs that may advance the art of elastomeric articles, such as pneumatic tires and gas spring assemblies, for example.BRIEF DESCRIPTION

[0006] One example of an anaxisymmetric reinforcing ring in accordance with the subject matter of the present disclosure can be dimensioned to be at least partiallyembedded within an associated elastomeric article, such as may have an associated article wall at least partially formed from elastomeric material. The anaxisymmetric reinforcing ring can have an axis of revolution extending longitudinally and a path of revolution that extends circumferentially around the axis of revolution.

[0031] Turning now to the drawings, it is to be understood that the showings are for purposes of illustrating examples of the subject matter of the present disclosure and that the examples shown and described herein are not intended to be limiting. Additionally, it will be appreciated that the drawings are not to scale and that portions of certain features and / or elements may be exaggerated for purpose of clarity and / or ease of understanding.

[0032] The subject matter of the present disclosure includes anaxisymmetric reinforcing rings that extend endlessly around an axis of revolution. The anaxisymmetric reinforcing rings include an annular path of revolution that extends endlessly around the axis of revolution. In at least some cases, the path of revolution can be circular in shape. It will be appreciated, however, that paths having other shapes or configurations are contemplated and could be used, such as elliptical shapes, ovoid shapes, polyroundshapes (i.e. , polygons with rounded corners or radii between adjacent sides in place of sharp corners or vertices), for example.

[0033] For purposes of clarity, terms such as axisymmetric, and the like, are interpreted as referring to bodies or constructions that include an annular wall with a uniform (or at least substantially uniform) cross-sectional profile that extends entirely around a longitudinal axis of the body or construction. Whereas, terms such as anaxisymmetric, and the like, broadly refer to endless annular bodies or constructions that include two or more cross-sectional profiles each extending only partially around the longitudinal axis (or axis of revolution) of the body or construction.

[0034] Anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure include at least two different cross-sectional profiles normal (i.e., perpendicular) to the path of revolution with each of the at least two different cross- sectional profiles located in a peripherally-different position on or along the annular path of revolution. In such an arrangement, one of the at least two different cross-sectional profiles will include at least one of a size (e.g., two-dimensional area), a shape (e.g., outermost peripheral contour) and / or a cross-sectional dimension (e.g., diameter, maximum cross-sectional dimension, minimum cross-sectional dimension) that is distinctly different than the corresponding size, shape and / or cross-sectional dimension of at least one other of the at least two different cross-sectional profiles. As a non-limiting example, such distinctly different (i.e., measurably and / or visually different) sizes, shapes and / or cross-sectional dimensions can beneficially result in reductions in weight and / or reductions in materials costs, such as in comparison with otherwise conventional reinforcing rings having a single larger or more complex cross-sectional that extends uniformly around the axis thereof. Additionally, in some cases, transitions between discrete sections having different cross-sectional profiles can operate as anchor points or areas for reinforcing layers or plies of the elastomeric article. In such cases, such anchoring can aid in inhibiting or at least resisting relative circular displacement between the layers or plies and the anaxisymmetric reinforcing ring, such as may occur during torsional load conditions or twising of the elastomeric article, for example.

[0035] That is, anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure will include two or more cross-sectionals profiles taken normalto the path of revolution that each extend only partially around the axis of revolution. In such an arrangement, changes in size, changes in shape and / or changes in configuration occur in spaced relation to one another around and / or along the anaxisymmetric reinforcing rings. In this respect, anaxisymmetric reinforcing rings do not have the generally uniform size, shape and configuration extending around the axis of revolution that conventional reinforcing rings that are otherwise known in the art typically include.

[0036] As one non-limiting example, anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure can include at least first and second cross-sectional profiles normal (i.e., perpendicular) to the path of revolution. The first cross-sectional profile can include at least one of a first cross-sectional size (e.g., two- dimensional area), a first cross-sectional shape (e.g., an outermost peripheral contour), and / or a first cross-sectional dimension (e.g., a radius, a diameter, a maximum cross- sectional dimension, a minimum cross-sectional dimension). The second cross-sectional profile can include at least one of a second cross-sectional size (e.g., two-dimensional area), a second cross-sectional shape (e.g., an outermost peripheral contour), and / or a second cross-sectional dimension (e.g., a radius, a diameter, a maximum cross-sectional dimension, a minimum cross-sectional dimension) that is different from a corresponding one of the first cross-sectional size, the first cross-sectional shape and / or the first cross- sectional dimension. In such an arrangement, the first cross-sectional profile is disposed along a first circumferential portion of the anaxisymmetric reinforcing ring with the second cross-sectional profile disposed along a second circumferential portion of the anaxisymmetric reinforcing ring that is different from the first circumferential portion.

[0037] In some cases, the first cross-sectional profile can extend and be substantially uniform in size, shape and dimension along a first ring section. The second cross- sectional profile can extend and be substantially uniform in size, shape and dimension along a second ring section that is different from the first ring section. In some cases, the first ring section can extend around the axis of revolution through a first non-zero angle along the path of revolution, and the second ring section can extend around the axis of revolution through a second non-zero circumferential angle along the path of revolution.

[0038] In accordance with the subject matter of the present disclosure, anaxisymmetric reinforcing rings include an area of transition (also referred to herein asa transition zone) from one ring section to the next (e.g., from a ring section having a first cross-sectional profile to a ring section having a second, different cross-sectional profile). The number of areas of transition an anaxisymmetric reinforcing ring in accordance with the subject matter of the present disclosure includes will have a relation to the number of different ring sections the anaxisymmetric reinforcing ring includes.

[0039] Additionally, it will be appreciated that areas of transition of any type, kind and / or configuration can be used. For example, in some cases, the areas of transition can take the form of somewhat abrupt transitions from one cross-sectional profile to another that occur over a relatively short peripheral extent, such as may form shoulders or other discontinuous surface transitions. In some cases, such shoulders or other somewhat discontinuous surface transitions can include rounded or radiused transitions. In other cases, the areas of transition can take the form of elongated transition zones that smoothly morph or otherwise change from one cross-sectional profile to another cross- sectional profile, such as by terminating tangentially on or along one or both ends of the areas of transition, for example.

[0040] Having briefly described various details of anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure, FIGS. 1-7 illustrate nonlimiting examples of anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure that include exemplary combinations of different details, structures, features, configurations and / or arrangements. It will be recognized and understood that the subject matter of the present disclosure broadly relates to anaxisymmetric reinforcing rings, such as those that may be suitable for use with and / or be at least partially embedded within a wall of an elastomeric article. As such, the im practicality of showing and / or describing anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure having innumerable combinations of the different details, structures, features, configurations and / or arrangements disclosed herein will be recognized and understood. Accordingly, while it is possible that no one embodiment may be specifically shown and described as including a particular combination of different details, structures, features, configurations and / or arrangements that are otherwise disclosed herein, the subject matter of the present disclosure is intended to encompass any and all combinations of different details,structures, features, configurations and / or arrangements shown and described herein, and, without limitation, that any suitable arrangement of features and components, in any combination, can be used. Thus, it is to be distinctly understood claims directed to any such combination of different details, structures, features, configurations and / or arrangements, whether or not specifically embodied herein, are intended to find support in the present disclosure.

[0041] With reference, now, to FIG. 1 , an anaxisymmetric reinforcing ring ARR is shown as including an axis of revolution AXR and a path of revolution PRV extending endlessly around the axis of revolution and oriented generally perpendicular thereto. Anaxisymmetric reinforcing ring ARR also includes a first cross-sectional profile PF1 taken normal (i.e., perpendicular) to the path of revolution, as represented by normal arrow NML. Anaxisymmetric reinforcing ring ARR further includes a second cross- sectional profile PF2 taken normal to the path of revolution, as represented by normal arrow NML. First cross-sectional profile PF1 sweeps normally (i.e., perpendicularly) along path of revolution PRV through a first circumferential angle, which is represented in FIG. 1 by reference dimension CA1 , to at least partially define a first ring section RS1. In some cases, first ring section RS1 will have and maintain first cross-sectional profile PF1 extending uniformly along path of revolution PRV through first circumferential angle CA1.

[0042] Additionally, second cross-sectional profile PF2 of anaxisymmetric reinforcing ring ARR sweeps normally (i.e., perpendicularly) along path of revolution PRV through a second circumferential angle, which is represented in FIG. 1 by reference dimension CA2, to at least partially define a second ring section RS2. In a preferred arrangement, second ring section RS2 will have and maintain second cross-sectional profile PF2 extending uniformly along path of revolution PRV through second circumferential angle CA2. Additionally, anaxisymmetric reinforcing ring ARR includes transition zones TRZ at or along which the anaxisymmetric reinforcing ring converts, morphs or otherwise changes to, from and / or otherwise between one cross-sectional profile and another, such as to, from and / or between first and second cross-sectional profiles PF1 and PF2, for example.

[0043] With reference, now, to FIG. 2, anaxisymmetric reinforcing ring ARR is shown therein as including a plurality of first ring sections RS1a, RS1b and RS1c having first cross-sectional profile PF1 as well as a plurality of second ring sections RS2a, RS2b andRS2c having second cross-sectional profile PF2. The first ring sections are disposed around axis of revolution AXR and along path of revolution PRV with one of the second ring sections disposed between adjacent ones of the first ring sections. The exemplary embodiment in FIG. 2 differs from the exemplary embodiment in FIG. 1 at least in that a plurality of first and second ring sections are included. Additionally, the plurality of first ring sections are shown extending through two or more different circumferential angles and, as such, having two or more different circumferential lengths along path of revolution PRV. For example, in some cases, ring section RS1a can extend through a circumferential angle CA1a, second ring section RS1b can extend through a circumferential angle CA1b, and / or ring section RS1c can extend through a circumferential angle CA1c. In some cases, ring sections RS2a, RS2b and RS2c can extend through corresponding circumferential angles (e.g., circumferential angles CA2) having values approximately equal to circumferential angles CA1a, CA1b and CA1c. In other cases, ring sections RS2a, RS2b and RS2c can extend through corresponding circumferential angles (e.g., circumferential angles CA2) having different or unique angular extents and corresponding circumferential lengths. As such, it will be recognized and appreciated that any two or more ring sections having a common cross-sectional profile can have the same or different circumferential lengths.

[0044] With reference, now, to FIG. 3, anaxisymmetric reinforcing ring ARR is shown therein as including first cross-sectional profile PF1, second cross-sectional profile PF2, and a third cross-sectional profile PF3 taken normal to the path of revolution, as represented by normal arrow NML. Additionally, anaxisymmetric reinforcing ring ARR includes a plurality of first ring sections RS1 having the first cross-sectional profile, a plurality of second ring sections RS2 having the second cross-sectional profile, and a plurality of third ring sections RS3 having third cross-sectional profile PF3. Ring sections RS1 , RS2 and RS3 are disposed around axis of revolution AXR and along path of revolution PRV. In the exemplary arrangement shown, one of third ring sections RS3 is disposed circumferentially between adjacent ones of ring sections RS1 and RS2. Additionally, it will be appreciated that the plurality of first ring sections are shown extending through a common first circumferential angle CA1 , the plurality of second ring sections are shown extending through a common second circumferential angle CA2, andthe plurality of third ring sections are shown extending through a third circumferential angle, which is represented in FIG. 3 by reference dimension CA3, that is common thereto.

[0045] It will be appreciated anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure can include any suitable number of two or more distinct or otherwise distinguishable cross-sectional profiles, such as a quantity within a range of from 2-10 cross-sectional profiles could be used, for example. Additionally, it will be appreciated that any suitable number of one or more occurrences of each of the two or more distinct cross-sectional profiles could be used, such as may depend on the size of the overall circumferential size of the anaxisymmetric reinforcing ring. As a non-limiting example, a quantity of distinct occurrences within a range of from one (1 ) to two hundred and fifty (250) distinct occurrence could be used. Further, it will be appreciated that circumferential angles can vary from ring section-to-ring section with two or more ring sections having common circumferential angles and / or with two or more ring sections having different circumferential angles. As such, it will be appreciated that any combination of one or more circumferential angles can be used, such as one or more circumferential angles within a range of from approximately three (3) degrees to approximately three hundred fifty seven (357) degrees.

[0046] As discussed above, transition zones TRZ convert, morph or otherwise change anaxisymmetric reinforcing ring to, from and / or otherwise between one cross-sectional profile and an adjacent cross-sectional profile. In some cases, transition zone TRZ can smoothly and continuously alter the outer peripheral contour of the reinforcing ring such that seamless or tangential transition extends along one or more of two adjacent ring sections, such as is shown in FIG. 1 , for example, in which transition zones TRZ extend tangentially between ring sections RS1 and RS2. As another example, transition zones TRZ can take the form of somewhat abrupt transitions from one cross-sectional profile to another between adjacent ring sections that occur over a relatively short peripheral extent, such as may form shoulders or other discontinuous surface transitions. One example of a construction including transition zones TRZ having such configurations is shown in FIG. 3, for example. Alternately, in some cases, such shoulders or othersomewhat discontinuous surface transitions can include rounded or radiused transitions, such as are represented by transition zones TRZ in FIG. 2, for example.

[0047] Anaxisym metric reinforcing rings ARR are shown in FIGS. 1-3 at least partially embedded within an elastomeric wall EMW of an elastomeric article ART. Elastomeric wall EMW can be at least partially formed from an elastomeric material. In some cases, one or more layers or plies of reinforcing fabric or filaments can extend through at least a portion of the elastomeric wall. In some cases, such one or more layers or plies of reinforcing fabric or filaments can extend along, across, through or otherwise wrap at least partially around one or more anaxisymmetric reinforcing rings ARR that are at least partially embedded within the elastomeric wall, such as to anchor, retain or otherwise at least partially inhibit of the one or more reinforcing layers or plies relative thereto. Elastomeric article ART and / or elastomeric wall EMW thereof can include an outer surface portion OSP. Additionally, or in the alternative, elastomeric article ART and / or elastomeric wall EMW thereof can include an inner surface portion NSP. In some cases, inner surface portion NSP can at least partially define an article chamber ACH within elastomeric article ART, such as may contain a quantity of pressurized gas.

[0048] As discussed above, anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure can include any suitable number of two or more distinct or otherwise distinguishable cross-sectional profiles, such as a quantity within a range of from 2-10 cross-sectional profiles could be used, for example. Additionally, as discussed above, the two or more cross-sectional profiles can be distinct or otherwise distinguishable in size (e.g., two-dimensional area), shape (e.g., outermost peripheral contour) and / or cross-sectional dimension (e.g., radius, diameter, maximum cross- sectional dimension, minimum cross-sectional dimension) relative to a corresponding size, shape and / or cross-sectional dimension of at least one other of the at least two different cross-sectional profiles.

[0049] As a non-limiting example, FIG. 4 illustrates anaxisymmetric reinforcing ring ARR with two or more common cross-sectional shapes that have distinct sizes and cross- sectional dimensions. More specifically, FIG. 4 illustrates cross-sectional profiles PF1 and PF2 as having generally circular shapes with cross-sectional profile PF1 having a first cross-sectional dimension CD1 , represented by a diameter, and cross-sectional profilePF2 having a second cross-sectional dimension CD2, represented by a diameter, that is at least five (5) percent greater than first cross-sectional dimension CD1.

[0050] As another non-limiting example, FIG. 5 illustrates anaxisymmetric reinforcing ring ARR with two or more different cross-sectional shapes, two or more different cross- sectional sizes, two or more common shapes in different orientations, and two or more different cross-sectional dimensions. More specifically, FIG. 5 illustrates cross-sectional profiles PF1 and PF2 as having two different shapes with cross-sectional profile PF1 having a square cross-sectional shape and cross-sectional profile PF2 having a rectangular cross-sectional shape. Additionally, cross-sectional profile PF3 is shown as having a common cross-sectional shape with cross-sectional profile PF2 (e.g., rectangular) but disposed in a different orientation from profile PF2. Furthermore, cross- sectional profile PF1 has one or more cross-sectional dimensions CD1a and CD1b that differ from corresponding cross-sectional dimensions CD2a and CD2b of profile PF2 and / or differ from corresponding cross-sectional dimensions CD3a and CD3b of profile PF3. What’s more, Furthermore, cross-sectional dimensions CD2a and CD2b of profile PF2 can differ from one or more corresponding cross-sectional dimensions CD3a and CD3b of profile PF3. In a preferred arrangement, such dimensions differ from one another by at least five (5) percent.

[0051] As a further non-limiting example, FIG. 6 illustrates anaxisymmetric reinforcing ring ARR with two or more different shapes having approximately common cross- sectional dimensions in at least one corresponding direction. For example, cross- sectional dimensions CD1a and CD1b are approximately equal to one another and approximately equal to corresponding cross-sectional dimensions CD2a and CD2b of profile PF2. If included, cross-sectional profile PF3 can have cross-sectional dimensions CD3a and CD3b that are at least approximately common with one or more of the cross- sectional dimensions of cross-sectional profiles PF1 and PF2.

[0052] As still another non-limiting example, FIG. 7 illustrates anaxisymmetric reinforcing ring ARR with three or more different cross-sectional shapes, three or more different cross-sectional sizes, and three or more different cross-sectional dimensions. More specifically, FIG. 7 illustrates cross-sectional profiles PF1, PF2, and PF3 as having three different shapes with cross-sectional profile PF1 having an elliptical cross-sectionalshape, cross-sectional profile PF2 having a rectangular cross-sectional shape, and cross- sectional profile PF3 having a polyround cross-sectional shape. Cross-sectional profile PF1 has one or more cross-sectional dimensions CD1a and CD1b that differ from corresponding cross-sectional dimensions CD2a and CD2b of profile PF2 and / or differ from corresponding cross-sectional dimensions CD3a and CD3b of profile PF3. What’s more, cross-sectional dimensions CD2a and CD2b of profile PF2 can differ from one or more corresponding cross-sectional dimensions CD3a and CD3b of profile PF3. In a preferred arrangement, such dimensions differ from one another by at least five (5) percent and / or corresponding cross-sectional areas can differ from one another by at least three (3) percent.

[0053] It will be appreciated that anaxisymmetric reinforcing rings ARR can be formed from any suitable material or combination of materials. In some cases, configurations and arrangements of anaxisymmetric reinforcing rings ARR may be well suited for manufacture by way of polymeric molding processes (e.g., injection molding) and, as such, can be at least partially formed from one or more polymeric materials. Non-limiting examples of suitable polymeric materials can include natural and / or synthetic rubber, fiber-reinforced thermoplastics, unreinforced thermoplastics, and / or thermoplastic elastomers. Additionally, in some cases, anaxisymmetric reinforcing rings ARR can, optionally, include an annular reinforcing core at least partially embedded within the body of the anaxisymmetric reinforcing ring. It will be appreciated that such an annular reinforcing core can have an endless annular construction with a core cross-sectional profile normal to the path of revolution having any suitable size, shape and / or configuration. In some cases, an exterior surface of the annular reinforcing core could at least partially form one of the cross-sectional profiles (e.g., cross-sectional profile PF1) of the anaxisymmetric reinforcing ring. In other cases, the endless annular reinforcing core can be at least substantially-entirely embedded within the material or body of the anaxisymmetric reinforcing ring. All of such endless annular reinforcing cores are represented in at least FIGS. 4-7, 10 and 14 by dashed lines ARC.

[0054] Having described examples of anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure as well as elastomeric articles that include such anaxisymmetric reinforcing rings embedded therein, non-limiting examplesof assemblies that include elastomeric articles having one or more anaxisymmetric reinforcing rings are shown and described in hereinafter in connection with FIGS. 8-15.

[0055] As one example, a gas spring assembly 200 is shown in FIGS. 8-10 as having a longitudinally-extending axis AX and can include one or more end members, such as an end member 202 and an end member 204 that is spaced longitudinally from end member 202. A flexible spring member 206 can extend peripherally around axis AX and can be secured between the end members in a substantially fluid-tight manner such that a spring chamber 208 is at least partially defined therebetween.

[0056] Gas spring assembly 200 can be disposed between associated sprung and unsprung masses of an associated vehicle in any suitable manner. For example, one end member can be operatively connected to the associated sprung mass with the other end member disposed toward and operatively connected to the associated unsprung mass. As shown in FIGS. 8 and 9, for example, end member 202 can be secured on or along a first or upper structural component USC, such as an associated vehicle body BDY in FIG. 16, for example, and can be secured thereon in any suitable manner. For example, one or more securement devices 210, such as mounting studs, for example, can be included along end member 202. In some cases, the one or more securement devices (e.g., the mounting studs) can project outwardly from end member 202 and can be secured thereon in a suitable manner, such as, for example, by way of a flowed-material joint (not shown) or a press-fit connection (not identified). Additionally, such one or more securement devices can extend through mounting holes HLS in upper structural component USC and can receive one or more securement devices 212, such as threaded nuts, for example. As an alternative to one or more of securement devices 210, one or more threaded passages (e.g., blind passages and / or through passages) could be used in conjunction with a corresponding number of one or more threaded fasteners.

[0057] Additionally, a fluid communication port, such as a transfer passage 214, for example, can optionally be provided to permit fluid communication with spring chamber 208, such as may be used for transferring pressurized gas into and / or out of the spring chamber, for example. In the exemplary embodiment shown, transfer passage 214 extends through at least one of securement devices 210 and is in fluid communicationwith spring chamber 208. It will be appreciated, however, that any other suitable fluid communication arrangement could alternately be used.

[0058] End member assembly 204 can be secured on or along a second or lower structural component LSC, such as an axle AXL or a suspension component SCP in FIG. 16, for example, in any suitable manner. As one example, lower structural component LSC could include one or more mounting holes HLS extending therethrough. In such case, a securement device 216, such as a threaded fastener, for example, could extend through one of mounting holes HLS and threadably engage end member 204 or a component thereof to secure the end member on or along the lower structural component.

[0059] Flexible spring member 206 can be of any suitable size, shape, construction and / or configuration. As one example, flexible spring member 206 can include a flexible wall 218 that is at least partially formed from one or more layers or plies of elastomeric material (e.g., natural rubber, synthetic rubber and / or thermoplastic elastomer) and can optionally include one or more plies or layers of filament reinforcing material. Flexible wall 218 is shown extending in a longitudinal direction between opposing ends 220 and 222. In some cases, flexible spring member 206 can include a mounting bead disposed along either one or both of ends 220 and 222 of the flexible wall. In the arrangement shown in FIGS. 8-10, for example, mounting beads 224 and 226 are respectively disposed along ends 220 and 222. In accordance with the subject matter of the present disclosure, either or both of mounting beads 224 and / or 226 can include an anaxisymmetric reinforcing ring ARR that is at least partially embedded within the corresponding mounting bead.

[0060] It will be appreciated that the one or more end members can be of any suitable type, kind, construction and / or configuration, and can be operatively connected or otherwise secured to the flexible spring member in any suitable manner. In the arrangement shown in FIGS. 8-10, for example, end member 202 is of a type commonly referred to as a bead plate and includes an end member wall 228 with a mounting wall portion 228M and an outer peripheral wall portion 228P. End member 202 is secured to end 220 of flexible wall 218 using a crimped-edge connection in which an outer peripheral wall portion 228P of end member wall 228 is crimped or otherwise deformed around at least a portion of mounting bead 224 such that a substantially fluid-tight seal is formed therebetween, such as is represented in FIG. 10 by dashed line FTS.

[0061] Additionally, in the arrangement shown in FIGS. 8-10, end member 204 is shown as being of a type commonly referred to as a piston (or a roll-off piston). End member 204 has an outer surface 230 that abuttingly engages flexible spring member 206 such that a rolling lobe 232 is formed along flexible wall 218. As gas spring assembly 200 is displaced between compressed and extended conditions, rolling lobe 232 is displaced along outer surface 230 in a generally conventional manner. Additionally, it will be appreciated that the exterior of the end member can have any suitable size, shape and / or configuration, such as may be useful to provide one or more desired performance characteristics, for example.

[0062] As identified in FIG. 9, end member 204 includes an end member body 234 and extends from along a first or upper end 236 toward a second or lower end 238 that is spaced longitudinally from end 236. Body 234 includes a longitudinally-extending outer side wall 240 that extends peripherally about axis AX and at least partially defines outer surface 230. An end wall 242 is disposed transverse to axis AX and extends radially- inward from along a shoulder portion 244, which is disposed along the outer side wall toward end 240. Body 234 also includes an inner side wall 246 that extends longitud inal ly- outward beyond end wall 242 and peripherally about axis AX. Inner side wall 246 has an outer surface 248 that is dimensioned to receive end 222 of flexible spring member 206 such that a substantially fluid-tight seal can be formed therebetween. In some cases, a retaining ridge 250 can project radially-outward from along inner side wall 246 and can extend peripherally along at least a portion thereof.

[0063] In some cases, body 234 can also include an inner side wall 252 that extends longitudinally-inward into the body from along end wall 242. Inner side wall 252 can terminate at a bottom wall 254 that is approximately planar and can be disposed transverse to axis AX such that inner side wall 252 and bottom wall 254 at least partially define a cavity 256 within body 234. In some cases, one or more bridge walls 258 can, optionally, extend between and operatively interconnect outer side wall 240 and inner side wall 252.

[0064] An inner support wall 260 can be disposed radially-inward from outer side wall 240 and can extend peripherally about axis AX. In some cases, inner support wall 260 can form a hollow column-like structure that projects from along bottom wall 254 in alongitudinal direction toward end 238. In some cases, the distal end (not numbered) of outer side wall 240 and / or the distal end (not numbered) of inner support wall 260 can at least partially define a mounting plane MP formed along end 238 of the end member body. In this manner, body 234 can be supported, at least in part, by outer side wall 240 and / or inner support wall 260, such as on or along an associated structural member (e.g., lower structural component LSC in FIGS. 8 and 9).

[0065] In some cases, gas spring assembly 200 can also include a jounce bumper that is supported on or along one of the end members and dimensioned to abuttingly engage the other of the end members of the gas spring assembly. In such cases, axially applied loads or forces can be transmitted from one end member to the other member through abutting engagement with the jounce bumper. As one example, a jounce bumper 262 is shown as being supported on end member 204. Jounce bumper 262 can include an outer side surface 264 that extends longitudinally between a base end surface 266 and a distal end surface 268. Base end surface 266 can be disposed in abutting engagement along bottom wall 254 of end member body 234 and secured thereto in a suitable manner, such as by way of a snap-fit engagement with a bumper mount 270 disposed on or along end member body 234. In such cases, distal end surface 268 is disposed in facing relation to end member 202 and can abuttingly engage an inside surface 272 of end member 202 as gas spring assembly 200 undergoes full jounce conditions. Under such conditions, loads and / or forces can be reacted, communicated or otherwise transferred between end members 202 and 204 and the associated mounting structures through jounce bumper 264 in a conventional manner.

[0066] Body 234 can also include a central wall 274 that is disposed radially-inward from inner support wall 260 and forms a post-like structure that projects from along bottom wall 254 in a direction toward end 238. In some cases, central wall 274 can terminate in approximate alignment with mounting plane MP, such as is illustrated in FIG. 9, for example. End member 204 can optionally include one or more features or components suitable for use in securing the end member on or along an associated structural component. As one example, a securement device 276, such as a threaded insert, for example, can be molded into or otherwise captured and retained within central wall 274 and can be dimensioned to receivingly engage a complementary securement device(e.g., securement device 216) for securement of the end member on or along the associate structural component (e.g., lower structural component LSC). In some cases, a longitudinally-extending passage 278 can extend into central wall 274 from along mounting plane MP such that the complementary securement device can reach and engage securement device 276 or another suitable feature.

[0067] In some cases, a height or distance sensing device 280 can be, optionally, included, such as is shown in FIG. 9, for example. It will be appreciated that such a height or distance sensing device can be supported on or along an end member (e.g., one of end members 202 and 204) in any suitable manner. As one example, height sensing device 280 can be disposed within spring chamber 208 along end member 202 and can be secured thereto using suitable securement devices 282. Height sensing device 280 can be of any suitable type, kind and / or construction, such as an ultrasonic, photonbased, laser or radar sensor that transmits and receives ultrasonic, photonic and / or electromagnetic signals or waves WVS (FIG. 9), for example. Additionally, it will be appreciated that height sensing device 280 can be connected to other systems and / or components of a vehicle suspension system in any suitable manner. As shown in FIG. 9, height sensing device 280 includes a lead or connection 284 that can be used for such communication purposes, such as may correspond to or be otherwise indicated by sensing devices 528 and / or leads 530 of control system 522 in FIG. 16, for example.

[0068] Additionally, as indicated above, flexible wall 218 of flexible spring member 206 can be formed in any suitable manner and from any suitable material or combination of materials, such as by using one or more fabric-reinforced, elastomeric plies or layers and / or one or more un-reinforced, elastomeric plies or layers, for example. Typically, one or more fabric-reinforced, elastomeric plies and one or more un-reinforced, elastomeric plies will be used together and formed from a common elastomeric material, such as a synthetic rubber, a natural rubber or a thermoplastic elastomer. In other cases, however, a combination of two or more different materials, two or more compounds of similar materials, or two or more grades of the same material could be used.

[0069] Flexible wall 218 can include an outer surface 286 and can also include an inner surface 288 that can at least partially define spring chamber 208. Additionally, as identified in FIG. 10, flexible wall 218 can include an outer or cover ply 290 that at leastpartially forms outer surface 286, an inner or liner ply 292 that at least partially forms inner surface 288, and one or more reinforcing plies disposed between outer and inner surfaces 286 and 288. The one or more reinforcing plies can be of any suitable construction and / or configuration. For example, the one or more reinforcing plies can include one or more lengths of filament material that are at least partially embedded therein. It will be appreciated that the one or more lengths of filament material can be of any suitable type, kind and / or construction, such as monofilament polymeric strands, braided cotton yarn or bundled carbon fibers, for example. Furthermore, such one or more lengths of filament material could optionally be coated or otherwise treated, such as, for example, to improve adhesion with the adjacent plies or other surrounding material. For example, the filament material could be rubber coated, such that upon applying a layer of rubber over the filament material improved adhesion between the various layers could result during and / or after vulcanization, for example.

[0070] Additionally, it will be appreciated that the one or more lengths of filament material, if provided, can be oriented in any suitable manner. As one example, flexible wall 218 is shown in FIG. 8 as including a plurality of filament segments 294A of one reinforcing ply 296A disposed at one bias angle BA1 and a plurality of filament segments 294B of another reinforcing ply 296B disposed another bias angle BA2. It will be appreciated that any suitable bias angles can be used, such as bias angles within a range of from approximately 3 degrees to approximately 87 degrees, for example. In some cases, the filament segments can be disposed at approximately the same bias angle but oriented in the opposing direction, such as is represented in FIG. 8 by reference dimensions BA1 and BA2, for example. In some cases, either one of both of reinforcing plies 296A and / or 296B can extend along, across, through or otherwise at least partially wrap around anaxisymmetric reinforcing ring ARR, such as to anchor, retain or otherwise at least partially inhibit of the one or more reinforcing layers or plies relative thereto.

[0071] Another example of a gas spring assembly 300 is shown in FIGS. 11-14 as having a longitudinally-extending axis AX, and can include one or more end members, such as an end member 302 and an end member 304 that is spaced longitudinally from end member 302. A flexible spring member 306 can extend peripherally around axis AXand can be secured between the end members in a substantially fluid-tight manner such that a spring chamber 308 (FIG. 13) is at least partially defined therebetween.

[0072] Gas spring assembly 300 can be disposed between associated sprung and unsprung masses of an associated vehicle in any suitable manner. For example, one end member can be operatively connected to the associated sprung mass with the other end member disposed toward and operatively connected to the associated unsprung mass. As shown in FIG. 11 , for example, end member 302 is secured along a first or upper structural component USC, such as associated a vehicle body BDY in FIG. 16, for example, and can be secured thereon in any suitable manner. For example, one or more securement devices 310 (e.g., blind nuts) can be included along end member 302. The one or more securement devices can be secured on or along the end member in any suitable manner, such as, for example, by way of a flowed-material joint or a press-fit connection. Additionally, such one or more securement devices 310 can be dimensioned to receive corresponding securement devices 312 (e.g., threaded bolts), such as may extend through mounting holes HLS in upper structural component USC and threadably engage securement devices 310, for example.

[0073] One or more gas transfer ports 314 can, optionally, be provided on or along one or more of end members 302 and / or 304 to permit fluid communication with spring chamber 308, such as may be used for transferring pressurized gas into and / or out of the spring chamber. For example, gas transfer port can be dimensioned for attachment of a gas transfer line (e.g., one of gas transfer lines 520 in FIG. 16).

[0074] End member 304 can be secured along a second or lower structural component LSC, such as an axle AXL or a structural component SCP in FIG. 16, for example, in any suitable manner. For example, one or more securement devices 316 (e.g., blind nuts) can be included along end member 304. The one or more securement devices can be secured on or along the end member in any suitable manner, such as, for example, by way of a flowed-material joint or a press-fit connection. Additionally, such one or more securement devices 316 can be dimensioned to receive corresponding securement devices 318 (e.g., threaded bolts) such as may extend through mounting holes HLS in lower structural component LSC and threadably engage securement devices 316, for example.

[0075] It will be appreciated that the one or more end members can be of any suitable type, kind, construction and / or configuration, and can be operatively connected or otherwise secured to the flexible wall in any suitable manner. In the exemplary arrangement shown in FIGS. 11 -13, for example, end members 302 and 304 are of a type commonly referred to as bead plates. End member 302 is shown as being secured to a first end 320 of flexible spring member 306 and includes an end member wall 322 with a mounting wall portion 322M and an outer peripheral wall portion 322P. End member 302 is secured to end 320 of flexible spring member 306 using a crimped-edge connection in which outer peripheral wall portion 322P of end member wall 322 is crimped or otherwise deformed around at least a portion of a mounting bead 324 at least partially formed on or along first end 320 of flexible spring member 306 such that a substantially fluid-tight seal is formed therebetween, such as is represented in FIG. 13 by dashed line FTS, for example. Similarly, end member 304 is shown as being secured to a second end 326 of flexible spring member 306 and includes an end member wall 328 with a mounting wall portion 328M and an outer peripheral wall portion 328P. End member 304 is secured to end 326 of flexible spring member 306 using a crimped-edge connection in which outer peripheral wall portion 328P of end member wall 328 is crimped or otherwise deformed around at least a portion of a mounting bead 330 at least partially formed on or along second end 326 of flexible spring member 306 such that a substantially fluid-tight seal is formed therebetween, such as is represented in FIG. 13 by dashed line FTS, for example. In accordance with the subject matter of the present disclosure, either or both of mounting beads 324 and / or 330 can include an anaxisymmetric reinforcing ring ARR that is at least partially embedded within the elastomeric material of the corresponding mounting bead.

[0076] Gas spring assembly 300 is shown as being of a type commonly referred to as a convoluted or bellows-type construction, and it will be appreciated that any suitable type or kind of convoluted spring construction can be used. As such, the flexible spring member of gas spring assembly 300 can have any suitable number of one or more convoluted wall portions disposed between the opposing end members. In the exemplary embodiment shown in FIGS. 11 -14, flexible spring member 306 includes a girdle wall portion 332 disposed approximately midway along the flexible spring member. As such, flexible spring member 306 is shown as including a convoluted wall portion 334 extendingbetween the girdle wall portion and end member 302, and a convoluted wall portion 336 extending between the girdle wall portion and end member 304. In accordance with the subject matter of the present disclosure, girdle wall portion 332 can include an anaxisymmetric reinforcing ring ARR that is at least partially embedded therein that can function as a girdle hoop to at least partially inhibit radial expansion of girdle wall portion 332, such as may occur during use, for example.

[0077] Flexible spring member 306 includes a flexible wall 338 that extends longitudinally between first end 320 and second end 326. Flexible wall 338 extends peripherally around longitudinal axis, and can be formed in any suitable manner and from any suitable material or combination of materials, such as by using one or more fabric- reinforced, elastomeric plies or layers and / or one or more un-reinforced, elastomeric plies or layers, for example. Typically, one or more fabric-reinforced, elastomeric plies and one or more un-reinforced, elastomeric plies will be used together and formed from a common elastomeric material, such as a synthetic rubber, a natural rubber or a thermoplastic elastomer. In other cases, however, a combination of two or more different materials, two or more compounds of similar materials, or two or more grades of the same material could be used.

[0078] Flexible wall 338 can include an outer surface 340 and an inner surface 342, which can at least partially define spring chamber 308. Additionally, flexible wall 338 can include an outer or cover ply 344 that at least partially forms outer surface 340, an inner or liner ply 346 that at least partially forms inner surface 342, and one or more reinforcing plies disposed between outer and inner surfaces 340 and 342. The one or more reinforcing plies can be of any suitable construction and / or configuration. For example, the one or more reinforcing plies can include one or more lengths of filament material that are at least partially embedded therein. It will be appreciated that the one or more lengths of filament material can be of any suitable type, kind and / or construction, such as monofilament polymeric strands, braided cotton yarn or bundled carbon fibers, for example. Furthermore, such one or more lengths of filament material could optionally be coated or otherwise treated, such as, for example, to improve adhesion with the adjacent plies or other surrounding material. For example, the filament material could be rubber coated, such that upon applying a layer of rubber over the filament material improvedadhesion between the various layers could result during and / or after vulcanization, for example.

[0079] Additionally, it will be appreciated that the one or more lengths of filament material, if provided, can be oriented in any suitable manner. As one example, flexible wall 338 is shown in FIG. 11 as including a plurality of filament segments 348A of one reinforcing ply 350A disposed at one bias angle BA1 and a plurality of filament segments 348B of another reinforcing ply 350B disposed another bias angle BA2. It will be appreciated that any suitable bias angles can be used, such as bias angles within a range of from approximately 3 degrees to approximately 87 degrees, for example. In some cases, the filament segments can be disposed at approximately the same bias angle but oriented in the opposing direction, such as is represented in FIG. 11 by reference dimensions BA1 and BA2, for example.

[0080] In some cases, either or both of reinforcing plies 350A and / or 350B together with the filament segments thereof can be anchored within mounting beads 324 and / or 330, such as by being at least partially wrapped around anaxisymmetric reinforcing rings ARR that are at least partially embedded within the corresponding mounting beads. Additionally, or in the alternative, reinforcing plies 350A and 350B together with the filament segments thereof can extend through girdle wall portion 332, such as by extending along or being partially wrapped around an anaxisymmetric reinforcing ring ARR that is at least partially embedded within the girdle wall portion.

[0081] With reference, again, to gas spring assemblies 200 and 300 discussed above in connection with FIGS. 8-14, the end members thereof can be secured on or along a mounting bead on the end of a flexible spring member in any suitable manner, such as by press-fitting the mounting bead on or along a wall portion of the end member (e.g., end member 204). Alternately, the end members can be secured on or along a mounting bead on the end of the flexible spring member by using a crimped connection (e.g., end members 202, 302 and / or 304). With reference to FIG. 15, end member 202 is shown undergoing such a crimping process in which outer peripheral wall portion 228P of end member wall 228 is crimped or otherwise deformed at least partially around mounting bead 224, such as is represented in FIG. 15 by arrows CMP, for example. In such an arrangement, outer peripheral wall portion 228P at least partially captures the mountingbead in the radial direction. Additionally, in such an installed condition, outer peripheral wall portion 228P extends around (i.e., wraps around) the mounting bead such that at least a distal edge 228D of end member wall 228 is disposed within a bead recess BDR formed between mounting bead 224 and flexible spring member 206. In such an arrangement, outer peripheral wall portion 228P urges a bead sealing surface 298 and any sealing structures 298S that can, optionally, be included thereon of mounting bead 224 into sealing engagement with inner surface portion 272 of mounting wall portion 228M such that a fluid-tight seal is formed and maintained therebetween, such as is represented in FIGS. 10 and 13 by dashed lines FTS, for example.

[0082] It will be appreciated that the foregoing discussion of crimping or otherwise securing end member 202 on or along mounting bead 224 is equally applicable to crimping or otherwise securing end members 302 and 304 on or along respective mounting beads 324 and 330. However, for purposes of brevity, further discussion of such operations in connection with end members 302 and 304 is not repeated here. As nonlimiting examples, sealing structures 298S can take the form of one or more annular rings having a somewhat tapered or triangular cross-sectional shape that extend peripherally around axis AX along bead sealing surfaces 298. It will be appreciated, however, that such configurations are merely exemplary and that other arrangements and / or constructions could alternately be used. Again, it will be appreciated that such bead sealing surfaces and / or sealing structures are equally applicable to mounting beads 324 and / or 330.

[0083] As discussed above, it will be recognized and understood that anaxisymmetric reinforcing rings in accordance with the subject matter of the present disclosure can be at least partially embedded within the elastomeric wall of elastomeric articles in any one a variety of positions. As non-limiting examples, anaxisymmetric reinforcing rings ARR can be disposed on or along flexible spring members 206 and / or 306, such as in the axial areas or positions identified by lines A-A and / or B-B in FIG. 9 and / or by lines C-C, D-D and / or E-E in FIG. 13.

[0084] FIG. 16 illustrates one example of a suspension system 500 operatively disposed between a sprung mass, such as an associated vehicle body BDY, for example, and an unsprung mass, such as associated wheels WHL, associated axles AXL and / orassociated suspension components SCP, for example, of an associated vehicle VHC. It will be appreciated that any one or more of the components of the suspension system can be operatively connected between the sprung and unsprung masses of the associated vehicle in any suitable manner. The suspension system includes one or more gas spring assemblies in accordance with the subject matter of the present disclosure as well as one or more damper assemblies that are operatively connected between the sprung and unsprung masses and together permit the sprung and unsprung masses of the associated vehicle to move in a somewhat controlled manner relative to one another, as discussed above.

[0085] As shown in FIG. 16, suspension system 500 can include a plurality of gas spring assemblies 502, such as have been described herein in accordance with the subject matter of the present disclosure, that are operatively connected between the sprung and unsprung masses of the vehicle. Additionally, suspension system 500 can include a plurality of damper assemblies 504 that are operatively connected between the sprung and unsprung masses of the vehicle. Depending on desired performance characteristics and / or other factors, the suspension system can include any suitable number and / or arrangement of one or more gas spring assemblies and one or more damper assemblies. For example, suspension system 500 in FIG. 16 includes four gas spring assemblies 502 and four damper assemblies 504 with one of the gas spring assemblies and one of the damper assemblies disposed toward each corner of the associated vehicle adjacent a corresponding one of associated wheels WHL. It will be appreciated, however, that other configurations and / or arrangements can alternately be used without departing from the subject matter of the present disclosure.

[0086] Furthermore, the one or more gas spring assemblies and the one or more damper assemblies can be operatively connected on, along or otherwise between the sprung and unsprung masses in any suitable manner. For example, depending on desired performance characteristics and / or other factors, the one or more gas spring assemblies can, in some cases, be provided and installed separately from the one or more damper assemblies. Additionally, or in the alternative, a gas spring assembly can, optionally, be assembled together with a damper assembly such that at least a portion of the gas spring assembly is axially coextensive with the damper assembly to form so-called gas springand damper assemblies that can then be operatively connected on, along or otherwise between the sprung and unsprung masses as a unit. It is to be recognized and understood that such axially-coextensive constructions, while optional, are contemplated herein and that gas spring assemblies in accordance with the subject matter of the present disclosure (as well as the components and assemblies thereof) can be used in connection with gas spring and damper assemblies.

[0087] Suspension system 500 also includes a pressurized gas system 506 operatively associated with at least gas spring assemblies 502 for selectively supplying pressurized gas (e.g., air) thereto and selectively transferring pressurized gas therefrom. In the exemplary arrangement shown in FIG. 16, pressurized gas system 506 includes a pressurized gas source, such as a compressor 508, for example, for generating pressurized air or other gases. A control device, such as a valve assembly 510, for example, is shown as being in communication with compressor 508 and can be of any suitable configuration or arrangement. In the exemplary embodiment shown, valve assembly 510 includes a valve block 512 with a plurality of valves 514 supported thereon. Valve assembly 510 can also, optionally, include a suitable exhaust, such as a muffler 516, for example, for venting pressurized gas from the system. Optionally, pressurized gas system 506 can also include a reservoir 518 in fluid communication with the compressor and / or valve assembly 510 and suitable for storing pressurized gas for an extended period of time (e.g., seconds, minutes, hours, weeks, days, months).

[0088] Valve assembly 510 is in communication with gas spring assemblies 502 through suitable gas transfer lines 520. As such, pressurized gas can be selectively transferred into and / or out of the gas spring assemblies through valve assembly 510 by selectively operating valves 514, such as to alter or maintain vehicle height at one or more comers of the vehicle, for example.
