DETAILED DESCRIPTION OF THE DISCLOSURE
One or more spacer sleeves may be disposed on the shaft to prevent side-to-side motion of the suspension component eyelet. Traditional spacer sleeves may be rigid. The spacer sleeves may be undersized (e.g. shorter than the distance from the eyelet to the frame) so that the clamping force holding the shaft and frame together (e.g. from the mounting bolt) is not applied to the eyelet. However, because the spacer sleeves are undersized, the eyelet and suspension component may still move laterally. The lateral movement may cause noise and excess wear on components, such as the bushing. The undersized spacer sleeves may also leave a gap between the spacer and the eyelet. Dirt, debris, and water may enter through the gap and contaminate the bushing or other components.
If the spacer sleeves are too wide, however, the clamping force may be transferred through the rigid spacer sleeve to the eyelet. The force on the eyelet may cause excess friction and wear on the eyelet, the frame, or other components.
The undersizing or oversizing of the spacers may be compensated for with an O-ring seal. For example, the O-ring may be disposed between the rigid spacer and the suspension component eyelet. However, because the O-ring may be smaller in width as compared to the spacer, the combined flexibility of the spacer and O-ring is limited. The limited flexibility may not sufficiently or significantly reduce the clamping force transferred to the eyelet. As a result, the clamping force transferred to the eyelet form the rigid spacer may cause excess wear on the eyelet or other parts of the suspension component. Further, the gap between the O-ring and the spacer provides an entry point for dirt, debris, and water. The two-piece spacer (e.g. the rigid spacer with O-ring) may be more complicated or expensive to manufacture and install on the mounting shaft.
A flexible, compressible, and/or deformable spacer may provide a solution to one or more of the problems described above. The flexible spacer may be installed between the suspension component eyelet and the frame of the bicycle. The spacer may be flexible in an axial direction. The axial flexibility may allow for the flexible spacer to locate the suspension component eyelet on the mounting shaft without causing excess friction or, in some cases, transferring all of the clamping force from the mounting bolt to the eyelet. Additionally, the flexible spacer may be in contact with the eyelet of the suspension component. By contacting the eyelet, the flexible spacer may prevent the ingress of dirt, debris, and water into the eyelet and bushing. In this way, the flexible spacer may be installed without an additional O-ring, thereby reducing cost and complexity. Further, the flexible spacer may compensate for a variation in the length or diameter of the mounting shaft, bushing, eyelet, or of the flexible spacer itself. For example, manufacturing tolerances may result in varying lengths across different mounting shafts, and one flexible spacer may be suitable for installation on mounting shafts of different lengths. In a further example, a flexible spacer may be suitable for installation with suspension component eyelets of varying widths, thereby reducing the number of different parts that may be produced for different bicycle and suspension component configurations.
The flexible properties of the spacer may be caused by or due to a geometry of the spacer, a material of the spacer, or a combination. For example, the spacer may be made from a polymer, plastic, or rubber with flexible properties. In another example, a portion of the spacer may have a narrow or articulated portion that may flex. In a further example, the spacer may include one or more circumferential ribs or ridges. Portions of the spacer between the ribs or ridges may compress under force, causing the spacer to flex.
Turning now to the drawings, FIG. 1 generally illustrates one example of a bicycle 100 on which a flexible spacer of one or more of the present embodiments may be installed. In the example shown, the bicycle 100 is a mountain bicycle. The bicycle 100 has a frame 102 supported on a front wheel 104 and a rear wheel 106. A drivetrain 108 is arranged to provide power to the rear wheel 106 via a chain 110. A front brake 112 and a rear brake 114 are arranged to slow rotation of the front wheel 104 and the rear wheel 106, respectively. A saddle 116 is provided to support the rider during use of the bicycle 100. A handlebar assembly 118 is arranged to control a direction of the front wheel 104 and communicate with the drivetrain 108, the front brake 112, and the rear brake 114 to control operation thereof. Further, a suspension component 120, such as a spring, a damper, or a combination thereof, may be attached to the frame 102 to improve ride quality. The flexible spacer 122 may be disposed between the frame 102 and the suspension component 120.
It is to be understood that the specific arrangement and illustrated components of the frame 102, front wheel 104, rear wheel 106, drivetrain 108, front brake 112, rear brake 114, saddle 116, and suspension component 120 are nonlimiting to the disclosed embodiments. For example, while the front brake 112 and the rear brake 114 are illustrated as hydraulic rim brakes, hydraulic disc brakes are contemplated and encompassed within the scope of the disclosure. In another example, different positions and orientations of the suspension component 120 are contemplated and encompassed within the scope of the disclosure. In a further example, while the suspension component 120 may be illustrated and/or described as a spring or a damper, other suspension components 120 other than a spring or a damper are contemplated and encompassed within the scope of the disclosure.
While the bicycle 100 depicted in FIG. 1 is a mountain bicycle, the flexible spacer 122, including the specific embodiments and examples disclosed herein as well as alternative embodiments and examples, may be implemented on other types of bicycles. For example, the disclosed flexible spacer may be used on road bicycles.
Referring to FIGS. 2-5, the suspension component 120 and the flexible spacer 122 are shown in greater detail. The suspension component 120 is shown installed on the bike frame 102. The suspension component 120 may be secured to a mounting portion 200 of the frame 102. The mounting portion 200 may include one or more extensions or mounting tabs 202. In some cases, the suspension component may be secured between two mounting tabs 202.
The suspension component 120 may include a mounting portion 204, such as an eyelet. The eyelet 204 may be located at an end of the suspension component 120. The eyelet 204 may ride on a mounting shaft 206 and thereby be secured to the bicycle frame 102 via the one or more mounting tabs 202. The eyelet 204 may allow for the suspension component 120 to rotate on the mounting shaft 206. The eyelet 204 may have a circular cross section. Other cross-sectional shapes for the eyelet 204 may be used.
In some cases, a bushing 208 may be disposed inward of the eyelet 204. For example, the eyelet 204 may ride on the mounting shaft 206 and rest on the bushing 208 disposed between the eyelet 204 and the mounting shaft 206. The bushing 208 may be press fit into or onto the eyelet 204. The bushing 208 may prevent the eyelet 204 and mounting shaft 206 from rubbing together and causing excess wear. Additionally, the bushing 208 may dampen a force transferred to the frame 102 from the suspension component 120. In some cases, the bushing 208 may be made from a polymer or non-metallic material. In some other cases, the bushing 208 may be made from metal. For example, the bushing 208 may be a bearing, such as a pin bearing.
The mounting shaft 206 may support the suspension component 120. For example, the eyelet 204 of the suspension component 120 (and/or the bushing 208) may be disposed on the mounting shaft 206. The mounting shaft may be sized and shaped to be disposed through the eyelet 204. A length of the mounting shaft 206 may extend a distance through the eyelet 204 to a mounting tab 202. In one example, the length of the mounting shaft 206 may extend the distance from one mounting tab 202 of the frame 102 to another mounting tab 202. The spacer 122 may extend the entirety of the distance or the length of the mounting shaft 206 from the eyelet 204 to the mounting tab 202. In some cases, the width the mounting shaft may be wider or narrower than the distance between the mounting tabs 202. A wider mounting shaft 206 may be more securely fixed to the mounting tabs 202, thereby providing a stable connection between the suspension component 120 and the frame 102. A narrower mounting shaft 206 may accommodate different frames 102 with different distances between the mounting tabs 202.
In some cases, the mounting shaft 206 may have a threaded portion. For example, the mounting shaft 206 may thread into a mounting tab 202 or a nut. The mounting shaft 206 may have a head, for example, opposite the threaded portion. The head may have a larger diameter than a hole in the mounting tab 202 through which a body of the mounting shaft 206 extends. The threaded portion, and/or the head may secure the mounting shaft 206 to the frame 102.
In some other cases, the mounting shaft 206 may be hollow or may have an interior void. A fixing member 210, such as a fastener or mounting bolt, may extend through the interior void of the mounting shaft 206. The fixing member 210 may thread into the mounting tab 202 or a nut. The fixing member 210 may secure the mounting shaft 206 to the frame 102. In this way, the fixing member 210 may exert or cause to be exerted a clamping force across the mounting tabs 202. For example, as the fixing member 210 is tightened, the mounting tabs 202 may be drawn together against the mounting shaft 206 due to the clamping force. In other words, opposite ends of the mounting shaft 206 abut the mounting tabs 202, respectively, after the fixing member 210 has been tightened. When the eyelet 204 is disposed between the mounting tabs 202, the flexible spacer 122 may reduce a transfer of the clamping force to the eyelet 204.
The flexible spacer 122 may be disposed between the eyelet 204 and the mounting tab 202 of the frame 102. The spacer 122 may abut a side of the eyelet 204 and an inner surface of the mounting tab 202. In some cases, a single spacer 122 may be used. In some other cases, two spacers 122 or another number of spacers 122 may be used. For example, one spacer 122 may be disposed on one side of the eyelet 204, and another spacer 122 may be disposed on the other side of the eyelet 204, such that the eyelet 204 is between the two spacers 122.
Referring to FIGS. 6A and 6B, the spacer 122 may have a body 600 that is cylindrical shell. The spacer 122 may be a single unitary part and/or formed from a single material. For example, the spacer 122 may include a body and a flexible portion that are a unitary part or formed from a single material. The spacer may be made from a flexible material. In some cases, the spacer 122 may be made from a non-metallic material. For example, the spacer 122 may be made from plastic, a polymer, or a rubber. The single unitary part may reduce the number of gaps (e.g. as compared to a rigid spacer and O-ring) through which dirt, debris, and water may ingress and cause excess wear on the eyelet 204, the mounting shaft 206, and the bushing 208. Further, the flexible spacer 122 may reduce the magnitude of the clamping force transferred to the eyelet 204.
The body 600 or shell of the spacer 122 may have an outer surface 602 (e.g., an outer annular surface) and an inner surface 604 (e.g., an inner annular surface). A wall 606 of the body or shell 600 may be defined by the outer surface 602 and the inner surface 604. The wall 606 may extend along a length of the body 600. In some cases, the wall 606 may be radially complete. For example, there may be no openings extending radially through the wall 606. In some other cases, the wall 606 may include one or more radial openings. The radial openings may extend less than a thickness of the wall 606 (e.g. less than the distance from the outer surface 602 to the inner surface 604), or may extend less than a length of the body 600. The inner surface 604 may conform to an outer surface of the mounting shaft 206. For example, a diameter of the inner surface 604 may be less than or equal to a diameter of an outer surface of the mounting shaft 206. For example, because the spacer 122 is flexible, the diameter of the inner surface 604 may be less than the diameter of the mounting shaft 206. The spacer 122 and the mounting shaft 206 may be press-fit together such that the spacer 122 is secured to the mounting shaft 206. The diameter of the inner surface 604 may provide a snug or secure fit on the mounting shaft 206.
The spacer may include a flexible portion 608. The flexible portion 608 may be disposed at an end of the body 600 or away from (e.g., adjacent to) the end of the body 600. For example, the flexible portion 608 may abut the eyelet 204 when the spacer 122 is installed. In some cases, a length of the flexible portion 608 may be less than the length of the body 600. A geometry of the flexible portion 608 may allow for the spacer 122 to flex. In an embodiment the flexible portion may include a variable cross-sectional area along a length. The changing cross sectional area may provide for a constant, adaptive, or variable spring rate along the length. For example, the flexible portion 608 may include one or more articulations 610. The articulations 610 may be one or more ribs, ridges, or valleys. The articulations 610, such as the ribs or ridges, may be circumferential. In some cases, the articulations 610 may have a different diameter than the body 600 (e.g. may be broader or narrower than the body 600) such that the ribs, ridges, or valleys 610 protrude from or are recessed from the body 600. The articulations 610 (including e.g. the spaces between the ribs or ridges) may compress under force, causing the spacer 122 to flex. For example, the clamping force may cause the spacer 122 to compress. While flexing, the overall length of the spacer 122 (e.g. including the body 600 and the flexible portion 608) may decrease.
While under compression, the spacer 122 may exert a bias force outward and axially. The bias force may be exerted on the eyelet 204 and/or one or more of the mounting tabs 202. A magnitude of the bias force may be dependent on or determined by a length of the flexible portion 608, a spring rate of the material of the spacer 122, and/or an extent to which the spacer 122 is compressed.
Referring to FIGS. 7-9B, the suspension component 120 and another example of the flexible spacer 122 are shown in greater detail. As shown in FIGS. 2-5, the suspension component 120 may installed on the bike frame 102, for example, secured to a mounting portion 200 of the frame 102 that may include one or more extensions or mounting tabs 202. The suspension component 120 may include an eyelet 204 that may allow for the suspension component 120 to rotate on a mounting shaft 206. In some cases, a bushing 208 may be disposed inward of the eyelet 204 so that the eyelet 204 may ride on the mounting shaft 206 and rest on the bushing 208. A fixing member 210, such as a fastener or mounting bolt, may secure the suspension component 120 to the frame mounting tabs 202.
A flexible spacer 122 may be disposed on one side of the eyelet 204. The flexible spacer 122 may locate the eyelet 204 axially on the mounting shaft 206 and prevent excess axial movement of the suspension component 120. In this example, a single flexible spacer 122 may be used. A single spacer 122 may reduce the overall number of parts needed to install the suspension component 120 on the bicycle 100. Further, a single spacer 122 may accommodate a larger variety of different suspension components 120 and bicycles 100 (e.g. as compared to two spacers or to one or more rigid spacers), thereby reducing manufacturing cost and complexity.
The mounting shaft 206 may have a collar 700. The collar 700 may have an outside diameter greater than an outside diameter of a body 702 of the mounting shaft 206. In this way, the collar 700 may protrude beyond the body 702 of the mounting shaft 206. The collar 700 may be sized and shaped to be disposable adjacent the eyelet 204 and opposite the spacer 122. In this way, the collar 700 may, alone or in conjunction with the spacer 122, locate the eyelet 204 axially on the mounting shaft 206 to prevent excess axial motion of the eyelet 204. The collar 700 may be disposed at an end of the mounting shaft 206 or away from (e.g., adjacent to) an end of the mounting shaft 206. In some cases, the collar 700 may be disposed between the eyelet 204 and the mounting tab 202. The collar 700 may be disposed on one side of the eyelet 204, opposite from another side of the eyelet 204 where the spacer 122 is disposed. In this way, the eyelet 204 may be disposed between the collar 700 and the spacer 122.
By integrating the collar 700 into the mounting shaft 206, the eyelet 204 of the suspension component 120 may be located between the mounting tabs 202 without two spacers 122 disposed on each side of the eyelet 204. The collar 700 may abut the mounting tab 202 and be held in place because the clamping force acts against and through the mounting shaft 206. In this way, the collar 700 may remain securely in place relative to the mounting tabs 202 and may have minimal axial motion. The spacer 122 disposed on the other side of the eyelet 204, abutting the eyelet 204 and another mounting tab 202, may exert an axial bias force against the eyelet 204. The axial bias force, further described below, may provide a bias to keep the eyelet 204 against the collar 700 and bias against any axial movement of the eyelet 204.
Referring to FIGS. 10-12B, the suspension component 120, the flexible spacer 122, and the mounting shaft 206 of FIG. 8 are illustrated. The flexible spacer 122, as illustrated, is installed on the mounting shaft 206 and is disposed between the eyelet 204 and a mounting tab 202. The fixing member 210 may apply a clamping force 1200 across the mounting tabs 202 to secure the mounting shaft 206 in place and, thereby, secure the suspension component 120 to the frame 102 via the eyelet 204.
In the example shown in FIGS. 10-12B, the flexible portion 608 of the flexible spacer 122 includes two ridges and two valleys (e.g. articulations) to form a wave shape. In other examples, the flexible portion 608 may include more or fewer ridges, more or fewer valleys, and/or may be shaped differently.
The clamping force may compress the spacer 122, reducing the overall length of the spacer 122 to a bias force length 1000 less than an axial length 1100 of the spacer 122. The axial length 1100 may be a length of the spacer 122 when no compressive or clamping force is applied across the spacer 122. When the spacer 122 has been compressed to the bias force length 1000, the spacer 122 may exert the bias force axially or outward. When installed adjacent the eyelet 204, the spacer 122 compressed to the bias force length 1000 may exert the bias force on the eyelet 204, thereby keeping the suspension component 120 in place and preventing excess side-to side movement of the suspension component 120. When a collar 700 of the mounting shaft 206 is disposed opposite the spacer 122, the bias force may push the eyelet 204 against the collar 700.
A magnitude of the bias force may depend on the bias force length 1000 and a spring rate of the spacer 122. For example, a smaller bias force length 1000 (e.g. the spacer compressed to a greater extent) may result in or cause the spacer 122 to exert a greater bias force than a longer bias force length 1000 (e.g. the spacer compressed to a lesser extent). A stiffer (e.g. higher spring rate) spacer 122 may exert a greater bias force than a less stiff (e.g. lower spring rate) spacer 122. Additionally or alternatively, the spring rate may depend on a geometry of the spacer 122 and/or a material of the spacer 122. For example, the ratio of the length of the flexible portion to the length of the body of the spacer may affect the spring rate. A greater length of the flexible portion versus the length of the body may reduce the spring rate, and a lesser length of the flexible portion versus the length of the body may increase the spring rate.
