The aperiodic annular reinforcement has an axis of rotation (AXR) and a path of rotation (PRV). The aperiodic annular reinforcement includes an annular wall extending annularly about the axis of rotation and includes a first cross-sectional profile and a second cross-sectional profile (PF1, PF2) taken perpendicular to the path of rotation. The first cross-sectional profile and the second cross-sectional profile are circumferentially spaced 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. Also included are elastomeric articles including one or more aperiodic annular reinforcements at least partially embedded within an elastomeric wall of the elastomeric article. In some cases, the elastomeric article at least partially forms a gas spring assembly (200). Also included are suspension systems (500) having such a gas spring assembly.

Description

Background Technology

[0001] This disclosure broadly relates to techniques for non-axisymmetric reinforcing rings sized to be at least partially embedded within elastomeric articles, such as flexible spring members in pneumatic tires and air spring assemblies. It also includes elastomeric articles having one or more such non-axisymmetric reinforcing rings, and assemblies having such elastomeric articles. In some cases, it may also include a vehicle suspension system comprising one or more air spring assemblies having such elastomeric articles.

[0002] In some cases, the subject matter of this disclosure may be specifically combined with wheeled vehicle applications and uses, and will be shown and described herein with reference to this. However, it should be understood that the subject matter of this disclosure may also be used in other applications and environments, and the particular uses shown and described herein are merely exemplary. For example, the subject matter of this disclosure may be used in combination with elastomeric articles and / or components of industrial machinery, its parts and / or other such equipment, as well as with non-wheeled vehicles, support structures, height adjustment systems and actuators. Therefore, the subject matter of this disclosure is not intended to be limited to uses associated with vehicles and / or the suspension systems of such vehicles.

[0003] In some cases, it may be desirable to reduce the overall weight of a vehicle and / or its suspension system. Reducing the weight of one or more tires of the vehicle and / or the various components of one or more air spring assemblies in the suspension system can be a contributing factor to achieving this goal. Traditionally, reinforcing rings, or so-called “curled wires,” have been widely used in the construction of elastomeric articles such as air spring assemblies and pneumatic tires. In such constructions, reinforcing rings are known to help establish a substantially non-extensible mounting crimp and / or, for example, to provide internal support for crimped connections along the mounting crimp of the air spring assembly. In many cases, such so-called “curled wires” are formed either from multiple segments of solid rods constructed as endless loops or from extremely long lengths of thin wire wound along and around itself into endless loops. In many cases, such conventional “curled wires” are formed from metallic materials.

[0004] While such known reinforcing elements typically provide sufficient reinforcing strength to achieve the desired performance of such elastomeric articles, they also contribute to the overall weight of the vehicle and its various components. In some cases, reinforcing rings for elastomeric articles may be formed at least partially of a nonmetallic 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 the mounting crimp of a flexible spring member and is formed from a flat strip of glass fiber reinforced plastic wound into coils of adjacent flat turns. Other such known constructions are shown and described in U.S. Patent No. 9,261,156, which discloses a reinforcing device that can be embedded within the mounting crimp or ring wall of a flexible spring member and is formed at least partially of a polymeric material. However, known reinforcing elements (including those formed at least partially of polymeric materials) have a generally axisymmetric configuration. Therefore, the outermost surface of such known reinforcing elements is substantially uniform around the entire reinforcing element or at least the basic whole of the reinforcing element in terms of cross-sectional size, shape and configuration.

[0005] While the known reinforcing ring construction has been widely used and various elastomer articles incorporating this known reinforcing ring construction have generally achieved success, it is believed that there is a desire to overcome the aforementioned and / or other disadvantages of the known construction while maintaining comparable or improved performance, ease of manufacture, ease of assembly, ease of fitting, reduced weight, and / or reduced manufacturing costs. Therefore, it is generally believed that it is desirable to develop new constructions and / or designs that can advance the technology of elastomer articles, such as, for example, pneumatic tires and gas spring assemblies. Summary of the Invention

[0006] An example of the dimensions of a non-axisymmetric reinforcing ring according to the subject matter of this disclosure may be designed to be at least partially embedded within an associated elastomeric article, such as having an associated article wall at least partially formed of an elastomeric material. The non-axisymmetric reinforcing ring may have a longitudinally extending axis of rotation and a rotation path extending circumferentially around the axis of rotation.

[0031] Turning now to the accompanying drawings, it should be understood that the illustrations are examples intended to illustrate the subject matter of this disclosure, and the examples shown and described herein are not intended to be limiting. Additionally, it should be understood that the drawings are not drawn to scale, and portions of particular features and / or elements may be exaggerated for clarity and / or ease of understanding.

[0032] The subject of this disclosure includes a non-axisymmetric reinforcing ring extending circumferentially around an axis of rotation. The non-axisymmetric reinforcing ring comprises a circumferential rotational path extending circumferentially around an axis of rotation. In at least some cases, the rotational path may be circular in shape. However, it should be understood that paths with other shapes or configurations (such as elliptical shapes, oval shapes, multi-arc shapes (i.e., polygons with rounded corners or arc radii between adjacent sides instead of sharp corners or vertices)) are contemplated and can be used, for example.

[0033] For clarity, terms such as axisymmetric are interpreted to refer to a body or structure comprising an annular wall having a uniform (or at least substantially uniform) cross-sectional profile extending entirely around the longitudinal axis of the body or structure. However, terms such as non-axisymmetric are broadly interpreted to refer to an endless annular body or structure comprising two or more cross-sectional profiles, each extending only partially around the longitudinal axis (or axis of rotation) of the body or structure.

[0034] The non-axisymmetric reinforcing ring according to the subject matter of this disclosure includes at least two distinct cross-sectional profiles perpendicular (i.e., orthogonal) to the path of rotation, wherein each of the at least two distinct cross-sectional profiles is located at a different position on or along the periphery of the annular path of rotation. In this arrangement, one of the at least two distinct cross-sectional profiles will include at least one of the following: size (e.g., two-dimensional area), shape (e.g., outermost peripheral profile), and / or cross-sectional dimensions (e.g., diameter, maximum cross-sectional dimension, minimum cross-sectional dimension), which is significantly different from the corresponding size, shape, and / or cross-sectional dimensions of at least one of the other at least two distinct cross-sectional profiles. As a non-limiting example, such significantly different (i.e., measurably and / or visually different) sizes, shapes, and / or cross-sectional dimensions can advantageously result in weight reduction and / or material cost reduction, for example, compared to a conventional reinforcing ring that otherwise has a single, larger, or more complex cross-sectional profile extending uniformly around its axis. Additionally, in some cases, the transition between discrete segments with different cross-sectional profiles can operate as anchor points or regions for reinforcing layers or cord layers of elastomeric articles. In such cases, this anchoring can help suppress or at least resist relative circumferential displacement between the layer or cord and the non-axisymmetric reinforcing ring, such as relative circumferential displacement that may occur under torsional load conditions or during the torsion of elastomer articles.

[0035] In other words, the non-axisymmetric reinforcing ring according to the subject matter of this disclosure will comprise two or more cross-sectional profiles cut perpendicular to the rotation path, each extending only partially around the axis of rotation. In this arrangement, variations in size, shape, and / or configuration occur around and / or along the non-axisymmetric reinforcing ring in a spaced-apart relationship. In this respect, the non-axisymmetric reinforcing ring does not possess the generally uniform size, shape, and configuration extending around the axis of rotation typically found in conventional reinforcing rings known in the art.

[0036] As a non-limiting example, the non-axisymmetric reinforcing ring according to the subject matter of this disclosure may include at least a first cross-sectional profile and a second cross-sectional profile perpendicular (i.e., orthogonal) to the path of rotation. The first cross-sectional profile may include at least one of a first cross-sectional size (e.g., two-dimensional area), a first cross-sectional shape (e.g., outermost peripheral shape), and / or a first cross-sectional dimension (e.g., radius, diameter, maximum cross-sectional dimension, minimum cross-sectional dimension). The second cross-sectional profile may include at least one of a second cross-sectional size (e.g., two-dimensional area), a second cross-sectional shape (e.g., outermost peripheral shape), and / or a second cross-sectional dimension (e.g., radius, diameter, maximum cross-sectional dimension, minimum cross-sectional dimension), which differs from a corresponding one of the first cross-sectional size, first cross-sectional shape, and / or first cross-sectional dimension. In this arrangement, the first cross-sectional profile is disposed along a first circumferential portion of the non-axisymmetric reinforcing ring, and the second cross-sectional profile is disposed along a second circumferential portion of the non-axisymmetric reinforcing ring that differs from the first circumferential portion.

[0037] In some cases, the first cross-sectional profile may extend along the first ring segment and is substantially uniform in size, shape, and dimensions. The second cross-sectional profile may extend along a second ring segment different from the first ring segment and is substantially uniform in size, shape, and dimensions. In some cases, the first ring segment may extend along the rotation path around the axis of rotation through a first non-zero angle, and the second ring segment may extend along the rotation path around the axis of rotation through a second non-zero circumferential angle.

[0038] According to the subject matter of this disclosure, a non-axisymmetric reinforcing ring includes a transition region (also referred to herein) from one ring segment to the next (e.g., from a ring segment having a first cross-sectional profile to a ring segment having a different second cross-sectional profile). The number of transition regions included in a non-axisymmetric reinforcing ring according to the subject matter of this disclosure will be related to the number of different ring segments included in the non-axisymmetric reinforcing ring.

[0039] Additionally, it should be understood that transition regions of any type, kind, and / or configuration may be used. For example, in some cases, a transition region may take the form of a slightly abrupt transition from one cross-sectional profile to another, occurring over a relatively short perimeter, such as forming a shoulder or other discontinuous surface transition. In some cases, such a shoulder or other slightly discontinuous surface transition may include a rounded or chamfered transition. In other cases, a transition region may take the form of an elongated transition area that smoothly deforms from one cross-sectional profile or otherwise changes to another, such as by terminating at or tangentially along one or both ends of the transition region.

[0040] Having briefly described the various details of the non-axisymmetric reinforcing ring according to the subject matter of this disclosure, Figures 1 to 7 Non-limiting examples of non-axisymmetric reinforcing rings according to the subject matter of this disclosure are illustrated, including exemplary combinations of different details, structures, features, configurations, and / or arrangements. It will be appreciated and understood that the subject matter of this disclosure relates broadly to non-axisymmetric reinforcing rings, such as those adapted for use with and / or at least partially embedded within the walls of an elastomeric article. Therefore, it will be appreciated and understood that it is impractical to show and / or describe numerous combinations of non-axisymmetric reinforcing rings having the different details, structures, features, configurations, and / or arrangements disclosed herein according to the subject matter of this disclosure. Thus, while no single embodiment may be specifically shown and described as including a particular combination of the different details, structures, features, configurations, and / or arrangements disclosed herein, the subject matter of this disclosure is intended to cover any and all combinations of the different details, structures, features, configurations, and / or arrangements shown and described herein, and is not limited to any combination of suitable features and component arrangements. Therefore, it should be clearly understood that, whether or not specifically embodied herein, any such combination of details, structures, features, configurations and / or arrangements in the claims are intended to find support in this disclosure.

[0041] Now for reference Figure 1 The non-axisymmetric reinforcement ring ARR is shown as including a rotation axis AXR and a rotation path PRV extending circumferentially around the rotation axis and oriented generally orthogonally to the rotation axis. The non-axisymmetric reinforcement ring ARR also includes a first section profile PF1 intercepted perpendicularly (i.e., orthogonally) to the rotation path, as indicated by the normal arrow NML. The non-axisymmetric reinforcement ring ARR also includes a second section profile PF2 intercepted perpendicularly to the rotation path, as indicated by the normal arrow NML. The first section profile PF1 sweeps perpendicularly (i.e., orthogonally) along the rotation path PRV through a first circumferential angle, which in... Figure 1The first ring segment RS1 is defined by a reference dimension CA1. In some cases, the first ring segment RS1 will have and maintain a first cross-sectional profile PF1 that extends uniformly along the rotation path PRV through the first circumferential angle CA1.

[0042] Additionally, the second section profile PF2 of the non-axisymmetric reinforcing ring ARR sweeps perpendicularly (i.e., orthogonally) along the rotation path PRV through the second circumferential angle, which is at... Figure 1 The second ring segment RS2 is defined by reference dimension CA2. In a preferred arrangement, the second ring segment RS2 will have and maintain a second cross-sectional profile PF2 that extends uniformly along the rotation path PRV through the second circumferential angle CA2. Additionally, the non-axisymmetric reinforcing ring ARR includes a transition zone TRZ, at or along which the non-axisymmetric reinforcing ring is transformed, deformed, or otherwise altered into one cross-sectional profile and another cross-sectional profile, transformed, deformed, or otherwise altered from one cross-sectional profile and another cross-sectional profile, and / or transformed, deformed, or otherwise altered between one cross-sectional profile and another cross-sectional profile, such as transformed, deformed, or otherwise altered into a first cross-sectional profile PF1 and a second cross-sectional profile PF2, transformed, deformed, or otherwise altered from the first cross-sectional profile and the second cross-sectional profile, and / or transformed, deformed, or otherwise altered between the first cross-sectional profile and the second cross-sectional profile.

[0043] Now for reference Figure 2 The non-axisymmetric reinforcing ring ARR is shown herein as comprising a plurality of first ring segments RS1a, RS1b, and RS1c having a first cross-sectional profile PF1 and a plurality of second ring segments RS2a, RS2b, and RS2c having a second cross-sectional profile PF2. The first ring segments are arranged about the axis of rotation AXR and along the path of rotation PRV, and one of the second ring segments is arranged between adjacent first ring segments. Figure 2 Exemplary implementations and Figure 1The exemplary embodiments differ at least in that they include a plurality of first and second ring segments. Additionally, the plurality of first ring segments are shown extending through two or more different circumferential angles, thus having two or more different circumferential lengths along the rotation path PRV. For example, in some cases, ring segment RS1a may extend through circumferential angle CA1a, second ring segment RS1b may extend through circumferential angle CA1b, and / or ring segment RS1c may extend through circumferential angle CA1c. In some cases, ring segments RS2a, RS2b, and RS2c may extend through corresponding circumferential angles (e.g., circumferential angle CA2) having values ​​approximately equal to those of circumferential angles CA1a, CA1b, and CA1c. In other cases, ring segments RS2a, RS2b, and RS2c may extend through corresponding circumferential angles (e.g., circumferential angle CA2) having different or unique angular ranges and corresponding circumferential lengths. Therefore, it will be appreciated and understood that any two or more ring segments having a common cross-sectional profile may have the same or different circumferential lengths.

[0044] Now for reference Figure 3 The non-axisymmetric reinforcing ring ARR is shown herein as comprising a first cross-sectional profile PF1, a second cross-sectional profile PF2, and a third cross-sectional profile PF3, taken perpendicular to the rotation path, as indicated by the normal arrow NML. Additionally, the non-axisymmetric reinforcing ring ARR includes a plurality of first ring segments RS1 having the first cross-sectional profile, a plurality of second ring segments RS2 having the second cross-sectional profile, and a plurality of third ring segments RS3 having the third cross-sectional profile PF3. The ring segments RS1, RS2, and RS3 are arranged about the rotation axis AXR and along the rotation path PRV. In the exemplary arrangement shown, one of the third ring segments RS3 is circumferentially arranged between adjacent ring segments of RS1 and RS2. Additionally, it should be understood that the plurality of first ring segments are shown extending through a common first circumferential angle CA1, the plurality of second ring segments are shown extending through a common second circumferential angle CA2, and the plurality of third ring segments are shown extending through a third circumferential angle, which... Figure 3 The reference dimension CA3 is used and is common to the multiple third ring segments.

[0045] It should be understood that the non-axisymmetric reinforcing ring according to the subject matter of this disclosure may include any suitable number of two or more different or otherwise distinguishable cross-sectional profiles, such as a number that may be used, for example, in the range of 2 to 10 cross-sectional profiles. Additionally, it should be understood that any suitable number of one or more occurrences of each of the two or more different cross-sectional profiles may be used, such as depending on the size of the total circumferential size of the non-axisymmetric reinforcing ring. As a non-limiting example, a number of different occurrences may be used in the range of one (1) to two hundred and fifty (250) different occurrences. Furthermore, it should be understood that the circumferential angle may vary between ring segments, wherein two or more ring segments have a common circumferential angle and / or wherein two or more ring segments have different circumferential angles. Therefore, it should be understood that any combination of one or more circumferential angles (such as one or more circumferential angles in the range of approximately three (3) degrees to approximately three hundred and fifty-seven (357) degrees) may be used.

[0046] As discussed above, the transition zone (TRZ) transforms, deforms, or otherwise alters the non-axisymmetric reinforcing ring into a cross-sectional profile and adjacent cross-sectional profiles, and / or between a cross-sectional profile and adjacent cross-sectional profiles. In some cases, the transition zone (TRZ) can smoothly and continuously change the outer periphery shape of the reinforcing ring, such that a seamless or tangential transition extends along one or more of the two adjacent ring segments, for example... Figure 1 As shown, the transition zone TRZ extends tangentially between ring segments RS1 and RS2. As another example, the transition zone TRZ can take the form of a slightly abrupt transition between adjacent ring segments from one cross-sectional profile to another, occurring over a relatively short peripheral area, such as forming a shoulder or other discontinuous surface transition. For example, Figure 3 An example of a construction including a transition zone TRZ with such a configuration is shown. Alternatively, in some cases, such shoulder or other slightly discontinuous surface transitions may include rounded or chamfered transitions, such as those made by, for example, by Figure 2 The transition region TRZ in the text represents this.

[0047] Non-axisymmetric reinforcement ring ARR in Figures 1 to 3The image is shown as being at least partially embedded within the elastomeric wall EMW of the elastomeric article ART. The elastomeric wall EMW may be at least partially formed of an elastomeric material. In some cases, one or more layers or plies of reinforcing fabric or filament may extend through at least a portion of the elastomeric wall. In some cases, such one or more layers or plies of reinforcing fabric or filament may extend along, across, through, or otherwise at least partially around one or more non-axisymmetric reinforcing rings (ARRs), which are at least partially embedded within the elastomeric wall, such as to anchor, retain, or otherwise at least partially constrain one or more reinforcing layers or plies relative to the one or more non-axisymmetric reinforcing rings. The elastomeric article ART and / or its elastomeric wall EMW may include an outer surface portion (OSP). Additionally or alternatively, the elastomeric article ART and / or its elastomeric wall EMW may include an inner surface portion (NSP). In some cases, the inner surface portion (NSP) may at least partially define a product chamber (ACH) within the elastomeric article ART, such as a chamber capable of containing a quantity of pressurized gas.

[0048] As discussed above, the non-axisymmetric reinforcing ring according to the subject matter of this disclosure may include any suitable number of two or more different or otherwise distinguishable cross-sectional profiles, such as a number in the range of 2 to 10 cross-sectional profiles. Additionally, as discussed above, the two or more cross-sectional profiles may be different or otherwise distinguishable in size (e.g., two-dimensional area), shape (e.g., outermost perimeter shape), and / or cross-sectional dimensions (e.g., radius, diameter, maximum cross-sectional dimension, minimum cross-sectional dimension) relative to the corresponding size, shape, and / or cross-sectional dimensions of at least one of the at least two different cross-sectional profiles.

[0049] As a non-restrictive example, Figure 4 An example is given of a non-axisymmetric reinforced ring (ARR) with two or more common cross-sectional shapes, which have different sizes and cross-sectional dimensions. More specifically, Figure 4 Examples of cross-sectional profiles PF1 and PF2 are shown, with cross-sectional profile PF1 having a first cross-sectional dimension CD1 expressed as a diameter and cross-sectional profile PF2 having a second cross-sectional dimension CD2 expressed as a diameter, the second cross-sectional dimension being at least five percent (5%) larger than the first cross-sectional dimension CD1.

[0050] As another non-restrictive example, Figure 5 Examples are given of non-axisymmetric reinforced rings (ARRs) having 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, Figure 5Example shows two cross-sectional profiles PF1 and PF2 with different shapes, PF1 having a square cross-sectional shape and PF2 having a rectangular cross-sectional shape. Additionally, cross-sectional profile PF3 is shown having the same cross-sectional shape as PF2 (e.g., rectangular), but in a different orientation. Furthermore, PF1 has one or more cross-sectional dimensions CD1a and CD1b that differ from the corresponding cross-sectional dimensions CD2a and CD2b of PF2 and / or from the corresponding cross-sectional dimensions CD3a and CD3b of PF3. Furthermore, the cross-sectional dimensions CD2a and CD2b of PF2 may differ from one or more corresponding cross-sectional dimensions CD3a and CD3b of PF3. In a preferred arrangement, such dimensions differ from each other by at least five percent (5).

[0051] As a further non-limiting example, Figure 6 An example is illustrated of a non-axisymmetric reinforcing ring (ARR) having two or more different shapes, which have substantially common cross-sectional dimensions in at least one corresponding direction. For example, cross-sectional dimensions CD1a and CD1b are substantially equal to each other and substantially equal to the corresponding cross-sectional dimensions CD2a and CD2b of profile PF2. If included, profile PF3 may have cross-sectional dimensions CD3a and CD3b that are substantially common to one or more of the cross-sectional dimensions of profiles PF1 and PF2.

[0052] As yet another non-restrictive example, Figure 7 An example is a non-axisymmetric reinforced 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, Figure 7 Examples are given of three cross-sectional profiles PF1, PF2, and PF3 with different shapes: cross-sectional profile PF1 has an elliptical cross-sectional shape, cross-sectional profile PF2 has a rectangular cross-sectional shape, and cross-sectional profile PF3 has a multi-circular cross-sectional shape. Cross-sectional profile PF1 has one or more cross-sectional dimensions CD1a and CD1b that differ from the corresponding cross-sectional dimensions CD2a and CD2b of profile PF2 and / or from the corresponding cross-sectional dimensions CD3a and CD3b of profile PF3. Furthermore, the cross-sectional dimensions CD2a and CD2b of profile PF2 may differ from one or more corresponding cross-sectional dimensions CD3a and CD3b of profile PF3. In a preferred arrangement, such dimensions differ from each other by at least five percent (5) and / or the corresponding cross-sectional areas differ from each other by at least three percent (3).

[0053] It should be understood that the non-axisymmetric reinforcing ring (ARR) can be formed from any suitable material or combination of materials. In some cases, the configuration and arrangement of the ARR are well suited for manufacture by polymer molding processes (e.g., injection molding), and therefore can be formed at least partially from one or more polymeric materials. Non-limiting examples of suitable polymeric materials may include natural and / or synthetic rubber, fiber-reinforced thermoplastics, unreinforced thermoplastics, and / or thermoplastic elastomers. Additionally, in some cases, the ARR may optionally include an annular reinforcing core at least partially embedded within the body of the ARR. It should be understood that such an annular reinforcing core may have an endless annular configuration with a core cross-sectional profile perpendicular to the path of rotation, the core cross-sectional profile having any suitable size, shape, and / or configuration. In some cases, the outer surface of the annular reinforcing core may at least partially form one of the cross-sectional profiles (e.g., cross-sectional profile PF1) of the ARR. In other cases, the endless annular reinforcing core may be at least substantially completely embedded within the material or body of the ARR. All such unended annular reinforcing cores are at least Figures 4 to 7 , Figure 10 and Figure 14 The middle part is represented by the dashed line ARC.

[0054] Having already described examples of non-axisymmetric reinforcing rings according to the subject matter of this disclosure and examples of elastomeric articles including such non-axisymmetric reinforcing rings embedded therein, the following is combined with Figures 8 to 15 Non-limiting examples of components comprising an elastomeric article having one or more non-axisymmetric reinforcing rings are shown and described.

[0055] As an example, gas spring assembly 200 in Figures 8 to 10 The device is shown having a longitudinally extending axis AX and may include one or more end members, such as end member 202 and end member 204 longitudinally spaced apart from end member 202. Flexible spring member 206 may extend peripherally about axis AX and may be fixed between the end members in a substantially fluid-impermeable manner, such that spring chamber 208 is at least partially defined between the end members.

[0056] The gas spring assembly 200 can be positioned in any suitable manner between the associated sprung and unsprung mass of the associated vehicle. For example, one end member is operatively connected to the associated sprung mass, while another end member is positioned toward and operatively connected to the associated unsprung mass. Figure 8 and Figure 9 As shown, for example, end member 202 may be in the first or upper structural component USC (such as, for example) Figure 16The fastener is fixed to the associated vehicle body (BDY) or along the USC and can be secured to the component in any suitable manner. For example, the end member 202 may include one or more fasteners 210, such as mounting studs. In some cases, one or more fasteners (e.g., mounting studs) may protrude outward from the end member 202 and can be secured to the end member in a suitable manner (e.g., by means of a flowing material joint (not shown) or a press-fit connection (not shown)). Additionally, such one or more fasteners may extend through mounting holes HLS in the superstructure component USC and may receive one or more fasteners, such as threaded nuts 212. As an alternative to the one or more fasteners 210, one or more threaded channels (e.g., blind channels and / or through channels) may be used in conjunction with a corresponding number of one or more threaded fasteners.

[0057] Additionally, a fluid communication port, such as, for example, transfer channel 214, may be optionally provided to allow fluid communication with spring chamber 208, such as for transferring pressurized gas into and / or out of spring chamber. In the exemplary embodiment shown, transfer channel 214 extends through at least one of the fixtures 210 and is in fluid communication with spring chamber 208. However, it should be understood that any other suitable fluid communication arrangement may be used alternatively.

[0058] End member assembly 204 may, for example, be in any suitable manner in the second or lower structural member LSC (such as... Figure 16 The end member 204 is fixed to or along the lower structural member (LSC). As an example, the lower structural member LSC may include one or more extended mounting holes HLS passing through it. In this case, a fixing device 216 (such as a threaded fastener) may extend through one of the mounting holes HLS and threadedly engage the end member 204 or a component thereof to secure the end member to or along the lower structural member.

[0059] The flexible spring member 206 may have any suitable size, shape, construction, and / or configuration. As an example, the flexible spring member 206 may include a flexible wall 218, which is at least partially formed of one or more layers or plies of an elastomeric material (e.g., natural rubber, synthetic rubber, and / or thermoplastic elastomer), and may optionally include one or more plies or layers of filament reinforcement material. The flexible wall 218 is shown extending in a longitudinal direction between opposing ends 220 and 222. In some cases, the flexible spring member 206 may include mounting crimps disposed along one or both of the ends 220 and 222 of the flexible wall. Figures 8 to 10In the illustrated arrangement, for example, mounting flanges 224 and 226 are provided along ends 220 and 222, respectively. According to the subject matter of this disclosure, either or both of mounting flanges 224 and / or 226 may include a non-axisymmetric reinforcing ring (ARR) at least partially embedded within the corresponding mounting flange.

[0060] It should be understood that one or more end members can be of any suitable type, kind, construction and / or configuration, and can be operably connected to or otherwise secured to the flexible spring member in any suitable manner. Figures 8 to 10 In the illustrated arrangement, for example, end member 202 is of the type commonly referred to as a crimped plate, and includes an end member wall 228 having 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 connection, in which the outer peripheral wall portion 228P of end member wall 228 is deformed around at least a portion of the crimp of mounting crimp 224 or otherwise deformed such that a substantially fluid-impermeable seal is formed between the outer peripheral wall portion and the mounting crimp, such as in… Figure 10 The dashed line FTS represents this.

[0061] Additionally, in Figures 8 to 10 In the illustrated arrangement, end member 204 is shown as belonging to the type commonly referred to as a piston (or roll-off piston). End member 204 has an outer surface 230 that abuts against flexible spring member 206 such that a roll convex angle 232 is formed along flexible wall 218. As gas spring assembly 200 moves between a compressed state and an extended state, the roll convex angle 232 moves along outer surface 230 in a generally conventional manner. Additionally, it should be understood that the exterior of the end member can have any suitable size, shape, and / or configuration, such as that which can be used to provide one or more desired performance characteristics.

[0062] like Figure 9As indicated, end member 204 includes end member body 234 and extends from along a first or upper end 236 toward a second or lower end 238 longitudinally spaced from end 236. Body 234 includes a longitudinally extending outer sidewall 240 that extends peripherally about axis AX and at least partially defines outer surface 230. End wall 242 is disposed transversely to axis AX and extends radially inward along a shoulder portion 244 that is disposed along the outer sidewall toward end 240. Body 234 also includes an inner sidewall 246 that extends longitudinally outward beyond end wall 242 and extends peripherally about axis AX. Inner sidewall 246 has an outer surface 248 that is sized to receive end 222 of flexible spring member 206 such that a substantially fluid-impermeable seal can be formed between the outer surface and the end. In some cases, the retaining ridge 250 may project radially outward from along the inner sidewall 246 and may extend peripherally along at least a portion of the inner sidewall.

[0063] In some cases, the body 234 may further include an inner sidewall 252 extending longitudinally inward from the end wall 242 into the body. The inner sidewall 252 may terminate at a bottom wall 254, which is generally planar and may be disposed transversely to axis AX, such that the inner sidewall 252 and the bottom wall 254 at least partially define a cavity 256 within the body 234. In some cases, one or more bridging walls 258 may optionally extend between the outer sidewall 240 and the inner sidewall 252 and operatively interconnect the outer sidewall and the inner sidewall.

[0064] The inner support wall 260 may be radially inwardly disposed from the outer wall 240 and may extend peripherally about axis AX. In some cases, the inner support wall 260 may form a hollow columnar structure that protrudes longitudinally from the bottom wall 254 toward end 238. In some cases, the distal end (unnumbered) of the outer wall 240 and / or the distal end (unnumbered) of the inner support wall 260 may at least partially define a mounting plane MP formed along the end 238 of the end member body. In this way, the body 234 may be at least partially supported by the outer wall 240 and / or the inner support wall 260, such as in associated structural members (e.g., Figure 8 and Figure 9 The lower structural component (LSC) is supported on or along the associated structural member.

[0065] In some cases, the gas spring assembly 200 may also include a bump damper supported on or along one of the end members, and sized to adjacently engage another end member of the gas spring assembly. In such cases, axially applied loads or forces can be transferred from one end member to the other through the adjacent engagement with the bump damper. As an example, a bump damper 262 is shown supported on end member 204. Bump damper 262 may include an outer surface 264 extending longitudinally between a base end surface 266 and a distal end surface 268. The base end surface 266 may be configured to abut along the bottom wall 254 of the end member body 234 and be suitably secured to the end member body, such as by a snap-fit ​​engagement with a damper mount 270 disposed on or along the end member body 234. In this configuration, the distal end surface 268 is positioned to face the end member 202 and can be adjacent to the inner surface 272 of the end member 202 when the gas spring assembly 200 experiences a fully turbulent condition. In this configuration, loads and / or forces can be reacted, transferred, or otherwise transmitted between the end members 202 and 204 and the associated mounting structure in a conventional manner via the bump damper 264.

[0066] The main body 234 may also include a central wall 274, which extends radially inward from the inner support wall 260 and forms a columnar structure projecting along the bottom wall 254 in a direction toward the end 238. In some cases, the central wall 274 may terminate in a position substantially aligned with the mounting plane MP, such as, for example... Figure 9 As illustrated, the end member 204 may optionally include one or more features or components adapted to secure the end member to or along an associated structural member. As an example, a securing device 276 (such as a threaded insert, for example) may be molded into or otherwise captured and retained within the central wall 274, and its dimensions may be designed to receptively engage a complementary securing device (e.g., securing device 216) for securing the end member to or along an associated structural member (e.g., a lower structural member LSC). In some cases, a longitudinally extending channel 278 may extend from along the mounting plane MP into the central wall 274, allowing the complementary securing device to reach and engage securing device 276 or another suitable feature.

[0067] In some cases, a height or distance sensing device 280 may optionally be included, such as, for example, Figure 9As shown. It should be understood 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 an example, the height sensing device 280 may be disposed within a spring chamber 208 along end member 202 and may be secured to the end member using a suitable fastening device 282. The height sensing device 280 may be of any suitable type, kind, and / or construction, such as, for example, emitting and receiving ultrasonic waves, photons, and / or electromagnetic signals or wave WVS (wave- ... Figure 9 (Ultrasonic, photon-based laser, or radar sensors). Additionally, it should be understood that the height sensing device 280 can be connected in any suitable manner to other systems and / or components of the vehicle's suspension system. For example... Figure 9 As shown, the altitude sensing device 280 includes leads or connectors 284 that can be used for such communication purposes, such as those that can be connected to, for example, [other components]. Figure 16 The sensing device 528 and / or lead 530 of the control system 522 correspond to or are otherwise indicated by it.

[0068] Additionally, as noted above, the flexible wall 218 of the flexible spring member 206 can be formed in any suitable manner and from any suitable material or combination of materials, such as, for example, by using one or more fabric-reinforced elastomeric cord layers or layers and / or one or more unreinforced elastomeric cord layers or layers. Typically, one or more fabric-reinforced elastomeric cord layers and one or more unreinforced elastomeric cord layers are used together and formed from common elastomeric materials such as synthetic rubber, natural rubber, or thermoplastic elastomers. However, in other cases, combinations of two or more different materials, two or more compounds of similar materials, or two or more grades of the same material may be used.

[0069] The flexible wall 218 may include an outer surface 286 and may also include an inner surface 288 that at least partially defines the spring chamber 208. Additionally, as Figure 10As indicated, the flexible wall 218 may include an outer or covering cord layer 290 that at least partially forms the outer surface 286, an inner or lining cord layer 292 that at least partially forms the inner surface 288, and one or more reinforcing cord layers disposed between the outer surface 286 and the inner surface 288. The one or more reinforcing cord layers may have any suitable construction and / or configuration. For example, the one or more reinforcing cord layers may include one or more filament materials of one or more lengths at least partially embedded therein. It should be understood that the one or more filament materials of one or more lengths may be of any suitable type, kind, and / or construction, such as, for example, monofilament polymer strands, woven cotton yarn, or bundled carbon fibers. Furthermore, such one or more filament materials of one or more lengths may optionally be coated or otherwise treated, for example, to improve adhesion to adjacent cord layers or other surrounding materials. For example, the filament material may be rubber-coated, such that when a rubber layer is applied to the filament material, adhesion between the layers may be improved, for example, during and / or after vulcanization.

[0070] Additionally, it should be understood that, if available, one or more filaments of material of various lengths may be oriented in any suitable manner. As an example, flexible wall 218 in... Figure 8 The diagram shows a plurality of filament segments 294A comprising a reinforcing cord layer 296A set at one offset angle BA1 and a plurality of filament segments 294B comprising another reinforcing cord layer 296B set at another offset angle BA2. It should be understood that any suitable offset angle can be used, such as, for example, an offset angle in the range of about 3 degrees to about 87 degrees. In some cases, the filament segments may be set at approximately the same offset angle but oriented in opposite directions, such as in… Figure 8 The reference dimensions BA1 and BA2 are used to indicate this. In some cases, either or both of the reinforcing cord layers 296A and / or 296B may extend along, across, through, or otherwise at least partially wrap around the non-axisymmetric reinforcing ring ARR in order to anchor, retain, or otherwise at least partially restrain one or more reinforcing layers or cord layers relative to the non-axisymmetric reinforcing ring.

[0071] Another example of the gas spring assembly 300 is in Figures 11 to 14 The device is shown having a longitudinally extending axis AX and may include one or more end members, such as end member 302 and end member 304 longitudinally spaced from end member 302. A flexible spring member 306 may extend peripherally about axis AX and may be fixed between the end members in a substantially fluid-impermeable manner, such that spring chamber 308 ( Figure 13 It is at least partially defined between the end members.

[0072] The gas spring assembly 300 can be positioned in any suitable manner between the associated sprung and unsprung mass of the associated vehicle. For example, one end member is operatively connected to the associated sprung mass, while another end member is positioned toward and operatively connected to the associated unsprung mass. Figure 11 As shown, for example, end member 302 along the first structural member or upper structural member USC (such as, Figure 16 The associated vehicle body (BDY) is fixed to the component, for example, and can be fixed to the component in any suitable manner. For example, one or more fixing devices 310 (e.g., blind nuts) may be included along the end member 302. The one or more fixing devices can be fixed to or along the end member in any suitable manner, such as, for example, by a flow material joint or press fit connection. Additionally, such one or more fixing devices 310 may be sized to receive a corresponding fixing device 312 (e.g., a threaded bolt), such as a mounting hole HLS that may extend through and, for example, threadedly engage the fixing device 310 in the superstructure component USC.

[0073] One or more gas transfer ports 314 may optionally be disposed on or along one or more of the end members 302 and / or 304 to allow fluid communication with the spring chamber 308, such as for transferring pressurized gas into and / or out of the spring chamber. For example, the gas transfer ports may be sized for attaching gas transfer lines (e.g., Figure 16 (One of the gas transmission lines 520 in the process).

[0074] End member 304 may, for example, be positioned along the second or lower structural member LSC (such as...) in any suitable manner. Figure 16 The axle (AXL) or structural component (SCP) in the lower structural member 304 is fixed. For example, one or more fixing devices 316 (e.g., blind nuts) may be included along the end member 304. The one or more fixing devices may be fixed to or along the end member in any suitable manner, such as, for example, by a flow material joint or press fit connection. Additionally, such one or more fixing devices 316 may be sized to receive a corresponding fixing device 318 (e.g., a threaded bolt), such as a mounting hole HLS that may extend through and, for example, threadedly engage the fixing device 316 in the lower structural member LSC.

[0075] It should be understood that one or more end members can be of any suitable type, kind, construction and / or configuration, and can be operably connected to or otherwise secured to the flexible wall in any suitable manner. Figures 11 to 13In the exemplary arrangement shown, for example, end members 302 and 304 belong to the type commonly referred to as crimped plates. End member 302 is shown as being fixed to a first end 320 of a flexible spring member 306 and includes an end member wall 322 having a mounting wall portion 322M and an outer peripheral wall portion 322P. End member 302 is fixed to the end 320 of the flexible spring member 306 using a crimped connection, in which the outer peripheral wall portion 322P of the end member wall 322 is deformed around or otherwise around a crimp at least partially formed on or along a mounting crimp 324 formed on the first end 320 of the flexible spring member 306, such that a substantially fluid-impermeable seal is formed between the outer peripheral wall portion and the mounting crimp, such as in… Figure 13 The dashed line FTS is used to indicate this. Similarly, end member 304 is shown as fixed to the second end 326 of flexible spring member 306 and includes an end member wall 328 having a mounting wall portion 328M and an outer peripheral wall portion 328P. End member 304 is fixed to end 326 of flexible spring member 306 using a crimped connection, in which the outer peripheral wall portion 328P of end member wall 328 is deformed around or otherwise around at least a portion of a crimped edge formed on or along the second end 326 of flexible spring member 306 or along the second end of the crimped edge 330, such that a substantially fluid-impermeable seal is formed between the outer peripheral wall portion and the mounting crimped edge, such as in Figure 13 The dashed line FTS is used to indicate this. According to the subject matter of this disclosure, either or both of mounting crimps 324 and / or 330 may include a non-axisymmetric reinforcing ring (ARR) that is at least partially embedded in the elastomeric material of the corresponding mounting crimp.

[0076] The gas spring assembly 300 is shown as belonging to a type commonly referred to as a spiral or bellows-type construction, and it should be understood that any suitable type or kind of spiral spring construction can be used. Therefore, the flexible spring member of the gas spring assembly 300 may have any suitable number or number of spiral wall portions disposed between opposite end members. Figures 11 to 14 In the exemplary embodiment shown, the flexible spring member 306 includes an annular wall portion 332 disposed generally intermediately along the flexible spring member. Thus, the flexible spring member 306 is shown as including a spiral wall portion 334 extending between the annular wall portion and the end member 302, and a spiral wall portion 336 extending between the annular wall portion and the end member 304. According to the subject matter of this disclosure, the annular wall portion 332 may include a non-axisymmetric reinforcing ring ARR at least partially embedded therein, which can serve as an annular clamp to at least partially suppress radial expansion of the annular wall portion 332, such as radial expansion that may occur during use.

[0077] The flexible spring member 306 includes a flexible wall 338 extending longitudinally between a first end 320 and a second end 326. The flexible wall 338 extends peripherally about a longitudinal axis and can be formed in any suitable manner and by any suitable material or combination of materials, such as, for example, by using one or more fabric-reinforced elastomeric cord layers or layers and / or one or more unreinforced elastomeric cord layers or layers. Typically, one or more fabric-reinforced elastomeric cord layers and one or more unreinforced elastomeric cord layers are used together and formed from common elastomeric materials such as synthetic rubber, natural rubber, or thermoplastic elastomers. However, in other cases, combinations of two or more different materials, two or more compounds of similar materials, or two or more grades of the same material may be used.

[0078] The flexible wall 338 may include an outer surface 340 and an inner surface 342, the inner surface at least partially defining the spring chamber 308. Additionally, the flexible wall 338 may include an outer or covering fabric layer 344 at least partially forming the outer surface 340, an inner or lining fabric layer 346 at least partially forming the inner surface 342, and one or more reinforcing fabric layers disposed between the outer surface 340 and the inner surface 342. The one or more reinforcing fabric layers may have any suitable construction and / or configuration. For example, the one or more reinforcing fabric layers may include one or more filament materials of one or more lengths at least partially embedded therein. It should be understood that the one or more filament materials of one or more lengths can be of any suitable type, kind, and / or construction, such as, for example, monofilament polymer strands, woven cotton yarn, or bundled carbon fibers. Furthermore, such one or more filament materials of one or more lengths may optionally be coated or otherwise treated, for example, to improve adhesion to adjacent fabric layers or other surrounding materials. For example, the filament material may be rubber-coated, such that when the rubber layer is applied to the filament material, the adhesion between the layers may be improved, for example, during and / or after vulcanization.

[0079] Additionally, it should be understood that, if available, one or more filaments of material of various lengths may be oriented in any suitable manner. As an example, flexible wall 338... Figure 11 The diagram shows a plurality of filament segments 348A comprising a reinforcing cord layer 350A set at one offset angle BA1 and a plurality of filament segments 348B comprising another reinforcing cord layer 350B set at another offset angle BA2. It should be understood that any suitable offset angle can be used, such as, for example, an offset angle in the range of about 3 degrees to about 87 degrees. In some cases, the filament segments may be set at approximately the same offset angle but oriented in opposite directions, such as in… Figure 11 The reference dimensions BA1 and BA2 are used to represent this.

[0080] In some cases, either or both of the reinforcing fabric layers 350A and / or 350B, together with their filament segments, may be anchored within mounting seams 324 and / or 330, such as by winding at least partially around a non-axisymmetric reinforcing ring ARR, which is at least partially embedded within the corresponding mounting seam. Additionally or alternatively, the reinforcing fabric layers 350A and 350B, together with their filament segments, may extend through the ring wall portion 332, such as by winding along at least partially around a non-axisymmetric reinforcing ring ARR, which is at least partially embedded within the ring wall portion.

[0081] Please refer to the above text again. Figures 8 to 14 The gas spring assemblies 200 and 300 discussed herein may have end members secured to or along a mounting crimp on the end of a flexible spring member in any suitable manner, such as by press-fitting the mounting crimp to or along a wall portion of the end member (e.g., end member 204). Alternatively, the end members may be secured to or along a mounting crimp on the end of a flexible spring member (e.g., end members 202, 302, and / or 304) using a crimp connection. (See reference...) Figure 15 The end member 202 is shown undergoing a crimping process in which the outer peripheral wall portion 228P of the end member wall 228 is at least partially crimped or otherwise deformed around the mounting crimp 224, such as in Figure 15 The arrow CMP indicates this arrangement. In this arrangement, the outer peripheral wall portion 228P at least partially captures the mounting crimp in the radial direction. Additionally, in this mounting state, the outer peripheral wall portion 228P extends around (i.e., wraps around) the mounting crimp, such that at least the distal edge 228D of the end member wall 228 is positioned within the crimp recess BDR formed between the mounting crimp 224 and the flexible spring member 206. In this arrangement, the outer peripheral wall portion 228P presses the crimp sealing surface 298 of the mounting crimp 224 and any sealing structures 298S optionally included thereon into a sealing engagement with the inner surface portion 272 of the mounting wall portion 228M, such that a fluid-impermeable seal is formed and maintained between the crimp sealing surface and the inner surface portion, such as in… Figure 10 and Figure 13 The dashed line FTS represents this.

[0082] It should be understood that the foregoing discussion regarding the fixing of end member 202 on or along mounting flange 224 or otherwise, applies equally to the fixing of end members 302 and 304 on or along corresponding mounting flanges 324 and 330. However, for the sake of brevity, further discussion of such operations involving end members 302 and 304 will not be repeated here. As a non-limiting example, sealing structure 298S may take the form of one or more annular rings having a slightly tapered or triangular cross-sectional shape extending peripherally around axis AX along the flange sealing surface 298. However, it should be understood that such configurations are merely exemplary and other arrangements and / or constructions may be used alternatively. Similarly, it should be understood that such flange sealing surfaces and / or sealing structures also apply to mounting flanges 324 and / or 330.

[0083] As discussed above, it will be recognized and understood that the non-axisymmetric reinforcing ring according to the subject matter of this disclosure can be at least partially embedded in any of a variety of locations within the elastomeric wall of an elastomeric article. As a non-limiting example, the non-axisymmetric reinforcing ring ARR can be disposed on or along the flexible spring members 206 and / or 306, such as in a structure composed of… Figure 9 The lines AA and / or BB and / or by Figure 13 The axial regions or locations identified by the lines CC, DD, and / or EE.

[0084] Figure 16 An example of a suspension system 500 operatively disposed between sprung mass (such as, for example, the body (BDY) of the associated vehicle) and unsprung mass (such as, for example, the associated wheel (WHL), associated axle (AXL), and / or associated suspension component (SCP) of the associated vehicle's VHC). It should be understood that one or more components of the suspension system may be operatively connected between the sprung and unsprung mass of the associated vehicle in any suitable manner. The suspension system includes one or more gas spring assemblies and one or more damper assemblies according to the subject matter of this disclosure, which are operatively connected between the sprung and unsprung mass and together allow the sprung and unsprung mass of the associated vehicle to move relative to each other in a controlled manner, as discussed above.

[0085] like Figure 16As shown, the suspension system 500 may include a plurality of gas spring assemblies 502, such as those described herein according to the subject matter of this disclosure, which are operatively connected between the sprung and unsprung mass of the vehicle. Additionally, the suspension system 500 may include a plurality of damper assemblies 504 operatively connected between the sprung and unsprung mass of the vehicle. Depending on desired performance characteristics and / or other factors, the suspension system may include any suitable number and / or arrangement of one or more gas spring assemblies and one or more damper assemblies. For example, Figure 16 The suspension system 500 includes four gas spring assemblies 502 and four damper assemblies 504, wherein one gas spring assembly and one damper assembly are arranged adjacent to a corresponding wheel in the associated wheel WHL at each corner of the associated vehicle. However, it should be understood that other configurations and / or arrangements may be alternatively used without departing from the subject matter of this disclosure.

[0086] Furthermore, one or more gas spring assemblies and one or more damper assemblies can be operatively connected to, along, or otherwise between the sprung and unsprung masses in any suitable manner. For example, in some cases, depending on desired performance characteristics and / or other factors, one or more gas spring assemblies may be supplied and installed separately from one or more damper assemblies. Alternatively or additionally, the gas spring assembly may be optionally assembled with the damper assembly such that at least a portion of the gas spring assembly is axially co-extended with the damper assembly to form a so-called gas spring and damper assembly, which can then be operatively connected as a unit to, along, or otherwise between the sprung and unsprung masses. It will be appreciated and understood that such axially co-extended configurations, while optional, are contemplated herein, and gas spring assemblies (and their components and assemblies) according to the subject matter of this disclosure can be used in conjunction with gas spring and damper assemblies.

[0087] The suspension system 500 also includes a pressurized gas system 506, which is operatively associated with at least the gas spring assembly 502 for selectively supplying pressurized gas (e.g., air) to and selectively transferring pressurized gas from it. Figure 16In the exemplary arrangement shown, the pressurized gas system 506 includes a pressurized gas source, such as, for example, a compressor 508, for generating pressurized air or other gases. Control devices, such as, for example, a valve assembly 510, are shown in communication with the compressor 508 and can be of any suitable configuration or arrangement. In the exemplary embodiment shown, the valve assembly 510 includes a valve block 512 having a plurality of valves 514 supported thereon. The valve assembly 510 may also optionally include a suitable venting device, such as, for example, a muffler 516, for discharging pressurized gas from the system. Optionally, the pressurized gas system 506 may also include a reservoir 518 in fluid communication with the compressor and / or valve assembly 510 and adapted to store pressurized gas for extended periods (e.g., seconds, minutes, hours, weeks, days, months).

[0088] Valve assembly 510 is connected to gas spring assembly 502 via a suitable gas transmission line 520. Thus, by selectively operating valve 514 through valve assembly 510, pressurized gas can be selectively transmitted into and / or out of gas spring assembly, thereby changing or maintaining, for example, the vehicle height at one or more corners of the vehicle.
