The inner portion includes a first yam of lubricious yam material and a second yarn of material that is different than the first yarn. The first yarn substantially provides an inner bearing surface and the second yarn substantially provides an outer surface that is bonded to the outer portion. The first and second yarns are woven together so that the first yarn is woven in one of a weft direction corresponding to a circumferential direction of the journal bearing surface or a warp direction corresponding to an axial direction of the journal bearing surface to substantially provide the bearing surface and the second yarn is woven in a direction different than the first yarn to substantially provide the outer surface bonded to the outer portion.
Description
- This application is a divisional application of U.S. application Ser. No. 11/769,354, filed Jun. 27, 2007, which claims the benefit of U.S. Provisional Application Ser. No. 60/819,320, filed Jul. 7, 2006, and also to U.S. Provisional Application Ser. No. 60/871,669, filed Dec. 22, 2006, all which are incorporated herein by reference in their entirety.
- 1. Technical Field
- This invention relates generally to sleeve bearings, and more particularly to sleeve bearing assemblies having a self-lubricating inner journal bearing portion and an outer elastomeric portion for dampening shock loads, such as for use in a suspension system of a vehicle.
- 2. Related Art
- Vehicle suspension components work together to serve a variety of functions, such as maintain proper ride height, maintain wheel alignment, support vehicle weight, maintain the tires in contact with the ground surface, control the vehicle direction of travel, and provide a smooth ride by dampening shock loads. Some of the components are coupled together via sleeve bearings to allow relative movement therebetween. Commonly, the sleeve bearings are fabricated having an outer portion constructed of rubber or urethane and an inner portion constructed of lubricious journal bearing material. The outer portion provides the dampening characteristics desired, while the inner portion reduces friction between the coupled components to allow the relative movement therebetween in use.
- It is known to construct sleeve bearing assemblies, such as those described above, by knitting the inner portion first and injection molding the outer portion about the inner portion. The inner portion is known to be knitted from yarn compositions comprising a lubricious yam material, such as polytetrafluoroethylene (PTFE) fibers, and a structural yarn material, such as polyester fibers. The two yarns are knitted together such that the PTFE follows the pattern of the polyester. Upon knitting the inner portion, it is stretched over an oversized mandrel to remove circumferential slack from the fabric and then located in a mold cavity, whereupon the outer portion is injection molded about the inner portion.
- Although sleeve bearing assemblies constructed in accordance with the process described above can be generally effective in use, some improvements can be achieved. For example, the knitted sleeve bearing assemblies utilize an inefficient amount of PTFE in manufacture, given the PTFE follows the knitted pattern of the polyester. As a result, it has been determined that about three turns of PTFE are used in every revolution, and thus, only about 30 percent of the PTFE is actually required to provide a bearing surface, while the remaining 70 percent of the PTFE yam is not necessary for use as a bearing surface. This ultimately results in cost inefficiencies, given the PTFE is generally the most expensive fiber in the sleeve. Further, the resulting knitted inner portion typically allows the injected molten rubber to penetrate through the knitted yarns and into the bearing surface region of the sleeve. This occurs in part due to the need to stretch the fabric over the mandrel to remove slack from the fabric and because the knitted yams do not provide a structure tight enough to prevent the rubber from penetrating therethrough. As such, the overall friction reducing effectiveness of the sleeve is reduced. In addition, while performing the injection molding of rubber in the known knitted sleeves, the rubber bonding to the outer surface of the knitted portion can cause the knitted portion to stretch further circumferentially, thereby causing a crease to form in the knitted portion. When this occurs, the resulting product is scrap. Lastly, during the injection molding process, the mandrel becomes increasingly hotter from being exposed to the heat from the molten rubber, thereby presenting an assembly challenge to the operator stretching the inner portion over the mandrel. As such, the operator commonly wears heat resistant gloves, thus, complicating the job.
- A sleeve bearing assembly manufactured according to the present invention overcomes or greatly minimizes any limitations of the prior art, such as those described above, for example.
- A sleeve bearing assembly has an inner portion constructed from a plurality of separate yarns to provide a generally cylindrical inner journal bearing surface for receipt of a journal for relative movement therein and for engagement therewith. The yarns include a first yarn of lubricious yarn material and a second yarn of material that is different than the first yarn. The first yarn substantially provides the inner bearing surface and the second yam substantially provides an outer surface of the inner portion. The bearing assembly further has an elastic outer portion injection molded at least partially about the inner portion and bonded with the outer surface. The first and second yarns are woven together. The first yarn is woven in one of a weft direction corresponding to a circumferential direction of the journal bearing surface or a warp direction corresponding to an axial direction of the journal bearing surface to substantially provide the bearing surface. The second yarn is woven in a direction different than the first yarn to substantially provide the outer surface,
- In accordance with another aspect of the invention, a method of constructing a sleeve bearing assembly having a generally cylindrical inner portion with a journal bearing surface and an elastomeric outer portion extending at least partially about the inner portion is provided. The method includes constructing the inner portion on a loom by weaving a plurality of first and second yarns together to form the journal bearing surface with the first yarns being provided as a lubricious yarn and being woven in one of a weft direction corresponding to a circumferential direction of the journal bearing surface or a warp direction corresponding to an axial direction of the journal bearing surface. The method further includes weaving the second yarns in a direction different than the first yarns, and then disposing the woven inner portion in a mold cavity. Further, the method includes molding the outer portion with an elastomeric material at least partially about the inner portion so that the outer portion bonds to the inner portion.
- A sleeve bearing assembly manufactured in accordance with the present invention provides a uniform self-lubricating bearing surface, reduces friction relative to a journal received therein, provides a substantially continuous self-lubricating bearing surface, reduces the potential for scrap in manufacture, increases manufacturing efficiencies, reduces the overall cost associated with manufacturing the assembly, minimizes the use of expensive bearing surface materials, maximizes the percentage of total bearing surface material in contact with the journal, minimizes the use of yarn in construction of the inner portion, increases manufacturing efficiencies and reduces labor complexities, and increases the useful life of the sleeve bearing assembly.
- These and other objects, features and advantages will become readily apparent to those skilled in the art in view of the following detailed description of the presently preferred embodiments and best mode, appended claims, and accompanying drawings, in which:

FIG. 1 is a schematic perspective view of a sleeve bearing assembly constructed in accordance with one presently preferred embodiment of the invention; -

FIG. 6 is a schematic cross-sectional view of a woven inner portion constructed in accordance with yet another presently preferred embodiment; and -
FIG. 7 a chart showing the weave pattern of the woven inner portion ofFIG. 6 . - Referring in more detail to the drawings,
FIG. 1 shows asleeve bearing assembly 10 constructed according to one presently preferred embodiment of the invention. The sleeve bearingassembly 10 is particularly useful for applications requiring dampening and reduced friction support between members coupled to one another (not shown), such as in an anti-roll bar, a control arm, or other suspension locations within a suspension system of a vehicle, for example. The sleeve bearingassembly 10 has an inner portion 12 (FIG. 2 ) constructed from tightly woven yams and anouter portion 14 that is injection molded at least partially about theinner portion 12. Theouter portion 14 is formed from any suitable injection moldable dampening material, such as rubber or urethane compounds, for example, that adheres or bonds to theinner portion 12. Theinner portion 12 is woven from afirst multifilament yam 16, such as polyester, or PET filaments, preferably textured, or some other fiber exhibiting high loft with an affinity for adhering or bonding to the elastomeric material forming theouter portion 14 and asecond multifilament yarn 18, such as PTFE filaments (Teflon), polyoxymethalyne, or other materials exhibiting a low coefficient of friction. ThePET yarn 16 primarily serves a structural function, such as by facilitating the bonding of theinner portion 12 to theouter portion 14, and acting to prevent the molten elastomeric material of theouter portion 14 from penetrating into thePTFE yam 18. ThePTFE yam 18 provides a self-lubricating inner bearing surface 20 (FIGS. 1 and 2 ) to minimize friction against a journal surface (not shown). Accordingly, thesleeve bearing assembly 10 is able to both reliably dampen vibration and forces via theouter portion 14, while also minimizing friction between a journal surface and thebearing surface 20 via theinner portion 12. - As best shown in
FIG. 2 , one presently preferred embodiment of theinner portion 12 is woven from the first andsecond yams FIG. 3 . Theyarns PET yarn 16 is woven in a warp direction (in and out of the paper as viewed inFIG. 2 ) corresponding to an axial direction 21 (FIG. 1 ) of theassembly 10, while thePTFE yarn 18 is woven in the weft direction corresponding to a circumferential direction about theaxis 21. The pair oryarns PET yarn 16 forms anouter surface 23 of theinner portion 12 and thePTFE yarn 18 forms the bearingsurface 20. As mentioned, thePET yarn 16 acts primarily as a structural support or carrier for thePTFE yarn 18, and to provide a barrier to the molten elastomeric material into the bearing surface region during the injection molding process (FIG. 4 ). ThePTFE yarn 18 is woven with thePET yarn 16 in a satin weft-faced weave. Accordingly, both thePET yarn 16 and thePTFE yarn 18 are presented with a satin weave finish. In the example shown here, thePTFE yarn 18 is woven in a 7:1 satin weave pattern, as shown inFIG. 2 , though it could be different, if desired. Accordingly, the bearingsurface 20 is comprised entirely of thelubricious PTFE yarn 18, with the exception of the occasional single overlays of thePET yarn 16. As such, it is estimated that the bearing surface is comprised of about 80-85 percent of thePTFE yarn 18, thereby minimizing the static and dynamic coefficient of friction relative to the journal. The tubular weaving process on the narrow fabric needle loom provides a stitchedseam 25 that extends along the length of theinner portion 12. - The
PET warp yarn 16 is generally provided having a denier between about 200-1000, and is shown here as being about 600 denier. As such, thePET yarn 16 forms a compact, tight weave (individual yarns shown schematically in an expanded relation to one another for clarity), such that theyarn 16 is desirably maintained toward theouter surface 23 and thus, away from the bearingsurface 20. In addition, the relatively small denier, which lends to the tight weave pattern, contributes to the prevention of the molten elastomeric material of theouter portion 14 from penetrating through theouter surface 23 during the injection molding process. - As shown in
FIG. 4 , upon weaving theinner portion 12, the remaining operations are performed to construct thesleeve bearing assembly 10. The resultinginner portion 12 is preferably disposed on a mandrel of suitable size, preferably having an outer diameter approximating an inner diameter of theinner portion 12, and then located with a mold cavity of an injection mold machine. As such, the effort to place theinner portion 12 on the mandrel is minimized, given the inner portion is not stretched significantly in a circumferential direction. Theouter portion 14 is then formed by injecting the desired elastic material, such as rubber, under pressure into the mold cavity and at least partially about anouter surface 23 of theinner portion 11 Theouter portion 14 is allowed to cool to a predetermined temperature and/or for a predetermined amount of time, and then the resultingsleeve bearing assembly 10 is removed from the mold cavity. - With the
inner portion 12 being woven, as described above, the weave pattern presents thePTFE weft yarns 18 in a circumferential direction about theinner portion 12. As such, theweft yarns 18 provide theinner portion 12 with a relatively high hoop strength, thereby eliminating the aforementioned problem of forming a crease in theinner portion 12 during the injection molding process. Accordingly, the production of scrap is minimized. In addition, the increased hoop strength of theinner portion 12 increases the rigidity and integrity of the bearingsurface 20, thereby maximizing its useful life under load. - As shown in
FIG. 5 , another presently preferred construction of aninner portion 112 is shown wherein theinner portion 112 is constructed at least in part from material that bonds well with the rubberouter layer 10, as described above, oriented in the weft direction, such asPET weft yarns 118, for example. In this embodiment, the warp yarns are woven withlubricious warp yams 116, such as PTFE yarns, for example. Theweft yarns 118 are woven here, by way of example and without limitation, so that they extend over 3warp yarns 116 to provide anouter surface 123 of theinner portion 112, though they could extend over more warp yarns, if preferred for the intended application. For example, as shown inFIGS. 6 and 7 , yet another presently preferred construction of aninner portion 212 has circumferentially directedweft yarns 218 shown floating over 7 lubricious axially extendingwarp yarns 216. - The
lubricious warp yarns inner portions inner surfaces yarns lubricious warp yarns inner portions PET weft yams lubricious warp yarns 116. In addition, with theweft yams outer portion 14 described above, assurance is provided that theweft yams weft yarns lubricious warp yarns weft yarns inner portions - To further yet provide assurance against an end fray condition from occurring, a bonding agent or adhesive layer 50 (
FIG. 5 ) can be applied to the woven fabric of theinner portions FIG. 1 ) of theinner portions adhesive layer 50 can be applied in a variety of ways, such as in a spraying or coating process, for example. Theadhesive layer 50 can be provided as a single or multi-coat rubber-based aqueous adhesive, by way of example and without limitation, such as nitrile rubber or silicone rubber, for example. It should be recognized that other bonding agents are contemplated herein, and the aforementioned bonding agents represent only some possible selections. Theadhesive layer 50 also facilitates bonding between the woven fabric substrate and the natural rubber or styrene butadiene rubberouter layer 14. Theadhesive layer 50 is preferably applied to the desired portions of theouter surfaces adhesive layer 50 can be cured by hot air, for example, to facilitate the curing process. As mentioned, theadhesive layer 50 coating not only minimizes the further potential for end fray, but it also promotes a strong and reliable bond between theinner portions outer portion 14 during molding. - It is to be understood that other embodiments of the invention which accomplish the same function are incorporated herein within the scope of this invention. It is also to be understood that sleeve assemblies can be manufactured in a variety of shapes, sizes and diameters, such as by altering the number of
warp yarns 16 incorporated into the weave. In addition, the sleeve bearing assemblies can be utilized in a variety applications and industries other than those mentioned above. The invention is defined by the claims that issue from this application and any related applications.
