Description

TECHNICAL FIELD

The present disclosure relates to tire fabrication (manufacture) and, more specifically, to a clamp ring assembly that is configured for use during the fabrication of vehicle tires.

BACKGROUND

Clamp ring assemblies are commonly used during tire fabrication (e.g., to secure the tire) and typically include upper and lower clamp rings. The upper and lower clamp rings include threaded openings that are configured to receive bolts (e.g., to secure the tire and the clamp rings together), which are arranged into one or more bolt patterns. Over time, as a result of the repeated insertion and removal of the bolts (e.g., during connection and disconnection of the tire), the threading on the openings experiences wear (e.g., stripping or other such deterioration), which results in failure of the clamp rings and, ultimately, disposal of the clamp ring assembly, thereby adding significantly to the overall cost of tire fabrication. In an effort to increase the usable life of clamp ring assemblies, attempts have been made to create new threaded openings by welding additional material(s) and re-tapping the clamp rings. Such efforts, however, have proved futile in that welding increases the hardness of the clamp rings, thereby inhibiting (if not entirely preventing) proper tapping.

The present disclosure addresses these deficiencies and provides for an improved clamp ring assembly that includes removable and replaceable insert rings for the upper and lower clamp rings, which eliminates any need to re-tap the clamp rings and improves the usable life of the clamp ring assembly.

DETAILED DESCRIPTION

The present disclosure describes an improved clamp ring assembly for use in the fabrication of vehicle tires. The clamp ring assembly described herein includes: an upper clamp ring, an upper insert ring; a lower clamp ring; and a lower insert ring. The upper and lower insert rings are configured for removable connection to (engagement with) the upper and lower clamp rings, respectively, and increase the usable life of the clamp ring assembly by eliminating the need to replace the upper and/or lower clamp rings that would otherwise result as a result of wear.

With reference to FIGS. 1A-3, a known clamp ring assembly 10 is illustrated, which includes a lower (first) clamp ring 12 and an upper (second) clamp ring 14.

The lower clamp ring 12 includes: an inner section 16 with a (first) receiver 18 that defines a (first) receptacle (e.g., a conduit) 20 extending along a longitudinal (vertical) axis Y1 of the lower clamp ring 12; an intermediate section 22, which includes a plurality of (first) openings 24 and is spaced radially outward from the inner section 16; and outer section (e.g., a rim) 26, which is spaced radially outward from the intermediate section 22. The lower clamp ring 12 further includes; a (first) groove 28 (FIG. 3), which is annular (or generally annular) in configuration and is located at the interface between the inner section 16 and the intermediate section 22; a (second) groove 30, which is annular (or generally annular) in configuration and is formed in an outer wall 32 of the intermediate section 22; and a well 34, which is annular (or generally annular) in configuration and is located between the intermediate section 22 and the outer section 26 such that the well 34 extends radially outward from the outer wall 32 of the intermediate section 22. As seen in FIG. 3, the groove 28 extends in parallel (or generally parallel) relation to the longitudinal axis Y1 and the groove 30 extends in orthogonal (or generally orthogonal) relation to the longitudinal axis Y1 (and the groove 28).

The upper clamp ring 14 includes an inner section 36 with a (second) receiver 38 that defines a receptacle (conduit) 40 extending along a longitudinal (vertical) axis Y2 of the upper clamp ring 14; an intermediate section 42, which includes a plurality of (second) openings 44 and is spaced radially outward from the inner section 36; and outer section (rim) 46, which is spaced radially outward from the intermediate section 42.

Each of the openings 24, 44 defines a radial dimension (e.g., a diameter) R1 (FIGS. 1A, 2) and is threaded (tapped), which allows for the removable insertion of (threaded) bolts 48 (FIG. 8). As described in further detail below, the openings 24, 44 are arranged into a plurality of respective bolt patterns 50, 52 that are (rotationally) offset from each other by an equivalent (or approximately equivalent) angular distance. For example, in the particular embodiment illustrated, the lower clamp ring 12 includes twenty four openings 24i-24xxiv that are arranged into three (e.g., respective first, second, and third) bolt patterns 50i-50iii, each of which includes eight of the openings 24, and the upper clamp ring 14 includes twenty four openings 44i-44xxiv that are arranged into three (e.g., respective fourth, fifth, and sixth) bolt patterns 52i-52iii, each of which includes eight of the openings 44. More specifically, the (first) bolt pattern 50i is comprised of the openings 24i, 24iv, 24vii, 24x, 24xiii, 24xvi, 24xii, and 24xxii, the (second) bolt pattern 50ii is comprised of the openings 24ii, 24v, 24viii, 24xi, 24xiv, 24xvii, 24xx, and 24xxiii, and the (third) bolt pattern 50iii is comprised of the openings 24iii, 24vi, 24vii, 24xii, 24xv, 24xviii, 24xii, and 24xxiv, and the (fourth) bolt pattern 52i is comprised of the openings 44i, 44iv, 44vii, 44x, 44xiii, 44xvi, 44xix, 44xxii, the (fifth) bolt pattern 52ii is comprised of the openings 44ii, 44v, 44viii, 44xi, 44xiv, 44xvii, 44xx, and 44xxiii, and the (sixth) bolt pattern 52iii is comprised of the openings 44iii, 44vi, 44vii, 44xii, 44xv, 44xviii, 44xxi, and 44xxiv. As a result, the bolt patterns 50i, 50ii, 50iii and the bolt patterns 52i, 52ii, 52iii are (rotationally) offset from each other by an angular distance of (approximately) 45° (i.e., 360° divided by the number openings 24, 44 times the number of bolt patterns 50, 52) and the openings 24i-24xxiv and the openings 44i-44xxiv are (rotationally) offset from each other by an angular distance of (approximately) 15° (i.e., 360° divided by the number of openings 24, 44). It should be appreciated, however, that the particular number of bolt patterns 50, 52 and/or openings 24, 44 respectively included on the clamp rings 12, 14 may be varied in alternate embodiments without departing from the scope of the present disclosure. As such, embodiments are envisioned herein in which the number of bolt patterns 50, 52 and/or the number of openings 24, 44 may be increased or decreased. Additionally, while the clamp rings 12, 14 are illustrated as including identical numbers of openings 24, 44 and bolt patterns 50, 52, respectively, embodiments are also envisioned herein in which the clamp rings 12, 14 may include non-identical number of openings 24, 44 and bolt patterns 50, 52, respectively. For example, in various embodiments of the disclosure, it is envisioned that the number of openings 24 and/or bolt patterns 50 on the clamp ring 12 may exceed the number of openings 44 and/or bolt patterns 52 on the clamp ring 14 or that the number of openings 44 and/or bolt patterns 52 on the clamp ring 14 may exceed the number of openings 24 and/or bolt patterns 50 on the clamp ring 12.

During use of the clamp ring assembly 10, the aforementioned bolts 48 are threaded into the openings 24, 44. To increase the usable life of the clamp ring assembly 10, the bolts 48 are initially connected to clamp rings 12, 14 via insertion into the openings 24, 44 comprising the bolt patterns 50i, 52i, respectively. Upon appropriate wear of the openings 24, 44 (e.g., via repeated insertion and removal of the bolts 48), the bolt patterns 50i, 52i are abandoned and the bolts 48 are subsequently connected to clamp rings 12, 14 via the openings 24, 44 comprising the bolt patterns 50ii, 52ii, respectively. Thereafter, upon appropriate wear, the bolt patterns 50ii, 52ii are abandoned and the bolts 48 are subsequently connected to clamp rings 12, 14 via the openings 24, 44 comprising the bolt patterns 50iii, 52iii, respectively. Thereafter, upon appropriate wear, the clamp ring assembly 10 must be discarded and replaced, which results in increased costs of use. The present disclosure addresses this deficiency, however, and describes an improved clamp ring assembly 100, which will now be discussed with reference to FIGS. 4A-8.

The clamp ring assembly 100 is substantially similar in both structure and function to the clamp ring assembly 10 (FIGS. 1A-3) discussed above and, accordingly, in the interest of brevity, will only be discussed with respect to any differences therefrom. As such, identical reference characters will be utilized to refer to elements, structures, features, etc., common to the clamp ring assemblies 10, 100.

The clamp ring assembly 100 includes: a lower (first) clamp ring 102 (FIG. 4B); a lower (first) insert ring 104 (FIG. 7A), which is configured for removable (releasable) connection to the lower clamp ring 102; an upper (second) clamp ring 106 (FIG. 4A); and an upper (second) insert ring 108 (FIG. 7B), which is configured for removable (releasable) connection to the upper clamp ring 106.

To support use with a variety of tires, it is envisioned that the clamp rings 102, 106 may be provided in a variety of sizes. For example, it is envisioned that the clamp rings 102, 106 may define respective transverse cross-sectional dimensions (e.g., diameters) D1, D2 that lie substantially within the range of (approximately) 10 inches to (approximately) 24 inches, which may be either equal or unequal. For example, in various embodiments of the disclosure, it is envisioned that the clamp rings 102, 106 may be configured such that the transverse cross-sectional dimension D1 exceeds the transverse cross-sectional dimension D2, such that the transverse cross-sectional dimension D2 exceeds the transverse cross-sectional dimension D1, or such that the transverse cross-sectional dimensions D1, D2 are equal (or approximately equal).

The lower clamp ring 102 includes (defines) a plurality of openings 110 and a lower (first) channel 112, which is annular (or generally annular) in configuration and is configured to receive the lower insert ring 104 (FIGS. 7A, 8) such that the lower insert ring 104 is removably positionable within the lower channel 112. As seen in FIGS. 4B-6, the lower channel 112 is formed in the intermediate section 22 of the lower clamp ring 102 and is located between the grooves 28, 30 (FIG. 6). More specifically, the lower channel 112 defines an inner radial edge 114, which is located adjacent (or generally adjacent) to the groove 28 (e.g., at the interface between the inner section 16 and the intermediate section 22), and an outer radial edge 116, which is located adjacent (or generally adjacent) to the groove 30 (e.g., at the interface between intermediate section 22 and the outer section 26). The lower channel 112 is formed (configured) such that the openings 110 are located therein. More specifically, the lower channel 112 defines a radial dimension (width) R2, which extends in orthogonal (or generally orthogonal) relation to the longitudinal axis Y1 (FIG. 1B) and exceeds the radial dimension R1 defined by the openings 110 (e.g., such that the lower channel 112 entirely spans the openings 110), and an axial dimension (depth) X1, which extends in parallel (or generally parallel) relation to the longitudinal axis Y1 and extends from an outer surface 118 defined by the inner section 16 to the groove 30. In the particular embodiment illustrated, the lower channel 112 is configured such that the axial dimension X1 lies substantially within the range of (approximately) ¼ inch to (approximately) ½ inch (e.g., (approximately) 0.375 inches). It should be appreciated, however, that the particular dimensions of the lower channel 112 may be varied in alternate embodiments without departing from the scope of the present disclosure. As such embodiments in which the axial dimension X1 of the lower channel 112 may lie outside of the disclosed range are also envisioned herein.

The upper clamp ring 106 includes (defines) a plurality of openings 120 and an upper (second) channel 122, which is annular (or generally annular) in configuration and is configured to receive the upper insert ring 108 (FIG. 7B) such that the upper insert ring 108 is removably positionable within the upper channel 122. As seen in FIG. 4A, the upper channel 122 is formed in the intermediate section 42 of the upper clamp ring 106 and defines an inner radial edge 124, which is located at the interface between the inner section 36 and the intermediate section 42, and an outer radial edge 126, which is located at the interface between the intermediate section 42 and the outer section 46. The upper channel 122 is formed (configured) such that the openings 120 are located therein. More specifically, the upper channel 122 defines a radial dimension (width) R3, which extends in orthogonal (or generally orthogonal) relation to the longitudinal axis Y2 (FIG. 1A) and exceeds the radial dimension R1 defined by the openings 120 (e.g., such that the upper channel 122 entirely spans the openings 120), and an axial dimension (depth) X2, which extends in parallel (or generally parallel) relation to the longitudinal axis Y2. In the particular embodiment illustrated, the upper channel 122 is configured such that the axial dimension X2 lies substantially within the range of (approximately) ¼ inch to (approximately) ¹/₂ inch (e.g., (approximately) 0.375 inches). It should be appreciated, however, that the particular dimensions of the upper channel 122 may be varied in alternate embodiments without departing from the scope of the present disclosure. As such embodiments in which the axial dimension X2 of the upper channel 122 may lie outside of the disclosed range are also envisioned herein.

The channels 112, 122 may be formed through any suitable method of manufacture. For example, it is envisioned that the channels 112, 122 may be formed via the removal of material from the respective clamp rings 102, 106, or, alternatively, that the channels 112, 122 may be formed during manufacture of the respective clamp rings 102, 106 (e.g., during machining, casting, etc.).

In contrast to the clamp ring assembly 10 discussed above with respect to FIGS. 1A-3, in which each of the openings 24, 44 is threaded, the clamp rings 102, 106 include both threaded and non-threaded openings 110, 120, respectively. More specifically, in the particular embodiment illustrated, the bolt patterns 50i, 52i (FIG. 1B) include threaded openings 110i, 110iv, 110vii, 110x, 110xiii, 110xvi, 110xix, 110xxii, 120i, 120iv, 120vii, 120x, 120xiii, 120xvi, 120xix, 120xxii, and the bolt patterns 50ii, 50iii and 52ii, 52iii included non-threaded openings 110ii, 110iii, 110v, 110vi, 110viii, 110ix, 110xi, 110xii, 110xiv, 110vx, 110xvii, 110vxiii, 110xx, 110xxi, 110xxiii, 110xxiv and 120ii, 120iii, 120v, 120vi, 120viii, 120ix, 120xi, 120xii, 120xiv, 120vx, 120xvii, 120vxiii, 120xx, 120xxi, 120xxiii, 120xxiv, respectively. The removal (absence) of threading on the openings 110ii, 110iii, 110v, 110vi, 110viii, 110ix, 110xi, 110xii, 110xiv, 110vx, 110xvii, 110vxiii, 110xx, 110xxi, 110xxiii, 110xxiv and 120ii, 120iii, 120v, 120vi, 120viii, 120ix, 120xi, 120xii, 120xiv, 120vx, 120xvii, 120vxiii, 120xx, 120xxi, 120xxiii, and 120xxiv inhibits (if not entirely prevents) interference with insertion of the bolts 48 (FIG. 8), as described in further detail below.

With reference now to FIGS. 7A, 7B, and 8 in particular, the respective lower and upper insert rings 104, 108 will be discussed. In the particular embodiment of the disclosure illustrated, the insert rings 104, 108 are identical (or substantially identical) in configuration and, as such, in the interest of brevity, certain details regarding the insert ring 108 may be eliminated. It should be appreciated, however, that the following discussion is equally applicable to both the lower insert ring 104 and the upper insert ring 108.

The lower insert ring 104 is annular (or generally annular) in configuration and is configured for removable positioning within the lower channel 112 (FIG. 4B) (the upper insert ring 108 is likewise annular (or generally annular) in configuration and is configured for removable positioning within the upper channel 122). The lower insert ring 104 defines an axial dimension (thickness) T1, which extends in parallel (or generally parallel) relation to the longitudinal axis Y1 (FIG. 1B) of the lower clamp ring 102. In the particular embodiment illustrated, the lower insert ring 104 is configured such that the axial dimension Tl corresponds to (e.g., is equal (or approximately) equal to) the axial dimension X1 (FIG. 5) defined by the lower channel 112 and, as such, lies substantially within the range of (approximately) ¼ inch to (approximately) ½ inch (e.g., (approximately) 0.375 inches). It should be appreciated, however, that the particular dimensions of the lower insert ring 104 may be varied in alternate embodiments without departing from the scope of the present disclosure. As such, embodiments in which the axial dimension T1 may lie outside of the disclosed range are also envisioned herein. Embodiments are also envisioned in which the axial dimension T1 may be less than or greater than the axial dimension X1 defined by the lower channel 112.

The lower insert ring 104 includes (defines) a plurality of (third) openings 128, which are both threaded and non-threaded, as described in further detail below, and are configured in correspondence with (e.g., correspond in configuration and location to) the openings 110 (FIG. 4B) in the lower clamp ring 102 such that the openings 110, 128 are (rotatably) alignable. The upper insert ring 108 likewise includes (defines) a plurality of (fourth) openings 130, which are both threaded and non-threaded, as described in further detail below, and are configured in correspondence with (e.g., correspond in configuration and location to) the openings 120 in the upper clamp ring 106 such that the openings 120, 130 are (rotatably) alignable).

The openings 128 are arranged into a plurality of bolt patterns 132 that are (rotationally) offset from each other by an equivalent angular distance such that the bolt patterns 132 correspond to the bolt patterns 50 in the lower clamp ring 102. The openings 130 are likewise arranged into a plurality of bolt patterns 134 such that the bolt patterns 134 correspond to the bolt patterns 52 in the upper clamp ring 106. In the particular embodiment illustrated, the lower insert ring 104 includes twenty four openings 128i-128xxiv that are arranged into three (e.g., respective seventh, eighth, and ninth) bolt patterns 132i-132iii, each of which includes eight of the openings 128, and the upper insert ring 108 likewise includes twenty four openings 130i-130xxiv that are arranged into three (e.g., respective tenth, eleventh, and twelfth) bolt patterns 134i-134iii, each of which includes eight of the openings 130. More specifically, whereas the (seventh) bolt pattern 132i is comprised of non-threaded openings 128i, 128iv, 128vii, 128x, 128xiii, 128xvi, 128xix, and 128xxii, the (eighth) bolt pattern 132ii and the (ninth) bolt pattern 132iii are comprised of threaded openings 128ii, 128v, 128viii, 128xi, 128xiv, 128xvii, 128xx, 128xxiii and threaded openings 128iii, 128vi, 128vix, 128xii, 128xv, 128xviii, 128xxi, and 128xxiv, respectively. Likewise, whereas the (tenth) bolt pattern 134i is comprised of non-threaded openings 130i, 130iv, 130vii, 130x, 130xiii, 130xvi, 130xix, and 130xxii, the (eleventh) bolt pattern 134ii and the (twelfth) bolt pattern 134iii are comprised of threaded openings 130ii, 130v, 130viii, 130xi, 130xiv, 130xvii, 130xx, 130xxiii and threaded openings 130iii, 130vi, 130vix, 130xii, 130xv, 130xviii, 130xxi, and 130xxiv, respectively. As a result, the bolt patterns 132i, 132ii, 132iii and the bolt patterns 134i, 134ii, 134iii are (rotationally) offset from each other by an equivalent (or approximately equivalent) angular distance of (approximately) 45° (i.e., 360° divided by the number openings 128 (130) times the number of bolt patterns 132 (134), as discussed above with respect to the clamp rings 12, 14. It should be appreciated, however, that the particular number of bolt patterns 132, 134 and/or openings 128, 130 respectively included on the lower insert ring 104 and the upper insert ring 108 may be varied in alternate embodiments without departing from the scope of the present disclosure. As such, embodiments are envisioned herein in which the number of bolt patterns 132, 134 and/or the number of openings 128, 130 may be increased or decreased. Additionally, while the insert rings 104, 108 are illustrated as including identical numbers of openings 128, 130 and bolt patterns 132, 134, respectively, embodiments are also envisioned herein in which the insert rings 104, 108 may include non-identical number of openings 128, 130 and bolt patterns 132, 134, respectively. For example, in various embodiments of the disclosure, it is envisioned that the number of openings 128 and/or bolt patterns 132 on the insert ring 104 may exceed the number of openings 130 and/or bolt patterns 134 on the insert ring 108 or that the number of openings 130 and/or bolt patterns 134 on the insert ring 108 may exceed the number of openings 128 and/or bolt patterns 132 on the insert ring 104.

During use of the clamp ring assembly 100, the lower insert ring 104 is positioned within the lower channel 112 such that the openings 128 are aligned with the openings 110 (FIG. 4B), and the upper insert ring 108 is likewise positioned within the upper channel 122 such that the openings 130 are aligned with the openings 120. Thereafter, the bolts 48 (FIG. 8) are inserted into the openings 128 (and the openings 130). More specifically, one of the bolt patterns 132 (e.g., the bolt pattern 132i) and one of the bolt patterns 50 (e.g., the bolt pattern 50i) is utilized to connect the lower insert ring 104 to the lower clamp ring 102 by inserting a (first) plurality of the bolts 48 through the non-threaded openings 128i, 128iv, 128vii, 128x, 128xiii, 128xvi, 128xix, 128xxii and into the threaded openings 110i, 110iv, 110vii, 110x, 110xiii, 110xvi, 110xix, 110xxii. Likewise, one of the bolt patterns 134 (e.g., the bolt pattern 134i) and one of the bolt patterns 52 (e.g., the bolt pattern 52i) is utilized to connect the upper insert ring 108 to the upper clamp ring 106 by inserting a (second) plurality of the bolts 48 through the non-threaded openings 130i, 130iv, 130vii, 130x, 130xiii, 130xvi, 130xix, 130xxii and into the threaded openings 120i, 120iv, 120vii, 120x, 120xiii, 120xvi, 120xix, 120xxii.

Following connection of the lower insert ring 104 to the lower clamp ring 102 and connection of the upper insert ring 108 to the upper clamp ring 106, tire fabrication continues by connecting a tire 200 to the clamp ring assembly 100, as illustrated in FIGS. 9 and 10. More specifically, another of the bolt patterns 132 (e.g., the bolt pattern 132ii) is utilized to receive a (third) plurality of the bolts 48, which threadably engage the lower insert ring 104 (via the openings 128ii, 128v, 128viii, 128xi, 128xiv, 128xvii, 128xx, 128xxiii) and extend into the (non-threaded) bolt pattern 50ii in the lower clamp ring 102 (e.g., the openings 110ii, 110v, 110viii, 110xi, 110xiv, 110xvii, 110xx, 110xxiii), thereby directly connecting a lower end 202 of the tire 200 to the lower insert ring 104 and, thus, indirectly (operatively) connecting the lower end 202 of the tire 200 to the lower clamp ring 102. Consequently, the bolts 48 extending through the tire 200 and into the lower insert ring 104 engage only the lower insert ring 104 and are disengaged from the lower clamp ring 102. The remaining bolt pattern(s) in the lower insert ring 104 (e.g., the bolt pattern 132iii) remains open (available) for future use, as described in further detail below.

Likewise, another of the bolt patterns 134 (e.g., the bolt pattern 134ii) is utilized to receive a (fourth) plurality of the bolts 48, which threadably engage the upper insert ring 108 (via the openings 130ii, 130v, 130viii, 130xi, 130xiv, 130xvii, 130xx, and 130xxiii) and extend into the (non-threaded) bolt pattern 52ii in the upper clamp ring 106 (e.g., the openings 120ii, 120v, 120viii, 120xi, 120xiv, 120xvii, 120xx, 120xxiii, thereby directly connecting an upper end 204 of the tire 200 to the upper insert ring 108 and, thus, indirectly (operatively) connecting the upper end 204 of the tire 200 to the upper clamp ring 106. Consequently, the bolts 48 extending through the tire 200 and into the upper insert ring 108 engage only the upper insert ring 108 and are disengaged from the upper clamp ring 106. The remaining bolt pattern(s) in the upper insert ring 108 (e.g., the bolt pattern 134iii) remains open (available) for future use, as described in further detail below.

As indicated above, the absence (e.g., removal, elimination) of threading from the openings 128i, 128iv, 128vii, 128x, 128xiii, 128xvi, 128xix, and 128xxii in the lower insert ring 104 and the openings 130i, 130iv, 130vii, 130x, 130xiii, 130xvi, 130xix, and 130xxii in the upper insert ring 108 inhibits (if not entirely prevents) interference with insertion of the bolts 48 that may otherwise result (e.g., from axial misalignment of the thread patterns, mismatched, pitch, etc.) during connection of the insert rings 104, 108 to the clamp rings 102, 106, respectively, thereby facilitating and simplifying assembly. Similarly, the removal (elimination) of threading from the openings 110ii, 110iii, 110v, 110vi, 110viii, 110ix, 110xi, 110xii, 110xiv, 110vx, 110xvii, 110vxiii, 110xx, 110xxi, 110xxiii, and 110xxiv in the lower clamp ring 102 and the openings 120ii, 120iii, 120v, 120vi, 120viii, 120ix, 120xi, 120xii, 120xiv, 120vx, 120xvii, 120vxiii, 120xx, 120xxi, 120xxiii and 120xxiv in the upper clamp ring 106 inhibits (if not entirely prevents) interference with insertion of the bolts 48 that may otherwise result (e.g., from axial misalignment of the thread patterns, mismatched, pitch, etc.) during connection of the tire 200 to the insert rings 104, 108, respectively, thereby facilitating and simplifying assembly.

In certain embodiments of the disclosure, it is envisioned that the openings 128, 130 in one of the bolt patterns 132, 134 (e.g., the bolt patterns 132i, 134i) may include countersinks 136 (e.g., to enhance the connection between the insert rings 104, 108 and the clamp rings 102, 106, respectively), as illustrated in FIGS. 7A, 7B. As such, embodiments are envisioned herein in which the openings 128 in the lower insert ring 104 and the openings 130 included in the upper insert ring 108 may be non-identical. It should be appreciated, however, that the countersinks 136 may be eliminated in alternate embodiments of the disclosure (e.g., to reduce fabrication or other manufacturing costs), and that the present disclosure envisions embodiments in which the openings 128 in the lower insert ring 104 and the openings 130 included in the upper insert ring 108 may be identical (e.g., embodiments in which each of the openings 128, 130 may include, or may be devoid of, the countersinks 136).

To increase the usable life of the clamp ring assembly 100, upon appropriate wear of the openings 128 in the bolt pattern 132ii and the openings 130 in the bolt pattern 134ii (e.g., via repeated insertion and removal of the bolts 48 during connection and disconnection of the tire 200 (FIGS. 9, 10)), the bolt patterns 132ii, 134ii are is abandoned, and the bolts 48 are subsequently inserted into the lower insert ring 104 via the openings 128 comprising the bolt pattern 132iii and into the upper insert ring 108 via the openings 130 comprising the bolt pattern 134iii. Thereafter, upon appropriate wear of the openings 128 in the bolt pattern 132iii and the openings 130 in the bolt pattern 134iii (e.g., via repeated insertion and removal of the bolts 48 during connection and disconnection of the tire 200), the insert rings 104, 108 may be removed and replaced, which allows for continued use of the clamp rings 102, 106, thereby extending the usable life of the clamp ring assembly 100.

Persons skilled in the art will understand that the various embodiments of the disclosure described herein and shown in the accompanying figures constitute non-limiting examples, and that additional components and features may be added to any of the embodiments discussed hereinabove without departing from the scope of the present disclosure. Additionally, persons skilled in the art will understand that the elements and features shown or described in connection with one embodiment may be combined with those of another embodiment without departing from the scope of the present disclosure and will appreciate further features and advantages of the presently disclosed subject matter based on the description provided. Variations, combinations, and/or modifications to any of the embodiments and/or features of the embodiments described herein that are within the abilities of a person having ordinary skill in the art are also within the scope of the disclosure, as are alternative embodiments that may result from combining, integrating, and/or omitting features from any of the disclosed embodiments.

Use of broader terms such as “comprises,” “includes,” and “having” should be understood to provide support for narrower terms such as “consisting of,” “consisting essentially of,” and “comprised substantially of.” Accordingly, the scope of protection is not limited by the description set out above but is defined by any claims that follow and includes all equivalents of the subject matter of any claims.

In the preceding description, reference may be made to the spatial relationship between the various structures illustrated in the accompanying drawings, and to the spatial orientation of the structures. However, as will be recognized by those skilled in the art after a complete reading of this disclosure, the structures described herein may be positioned and oriented in any manner suitable for their intended purpose. Thus, the use of terms such as “above,” “below,” “upper,” “lower,” “inner,” “outer,” “left,” “right,” “upward,” “downward,” “inward,” “outward,” etc., should be understood to describe a relative relationship between the structures and/or a spatial orientation of the structures. Those skilled in the art will also recognize that the use of such terms may be provided in the context of the illustrations provided by the corresponding figure(s).

Additionally, terms such as “approximately,” “generally,” “substantially,” and the like should be understood to allow for variations in any numerical range or concept with which they are associated. For example, it is intended that the use of terms such as “approximately” and “generally” should be understood to encompass variations on the order of 25%, or to allow for manufacturing tolerances and/or deviations in design. For example, the term “generally parallel” should be understood as referring to configurations in with the pertinent components are oriented so as to define an angle therebetween that is equal to 180°±25% (e.g., an angle that lies within the range of (approximately) 135° to (approximately) 225°) and the term “generally orthogonal” should be understood as referring to configurations in with the pertinent components are oriented so as to define an angle therebetween that is equal to 90°±25% (e.g., an angle that lies within the range of (approximately) 67.5° to (approximately) 112.5°). The term “generally parallel” should thus be understood as referring to encompass configurations in which the pertinent components are arranged in parallel relation, and the term “generally orthogonal” should thus be understood as referring to encompass configurations in which the pertinent components are arranged in orthogonal relation.

Any claim is incorporated as further disclosure into the specification and represents embodiments of the present disclosure. Also, the phrases “at least one of A, B, and C” and “A and/or B and/or C” should each be interpreted to include only A, only B, only C, or any combination of A, B, and C.
