Abstract
An adjustable locator includes an adjuster plate that communicates with an upper section of a damper to affect a relative orientation between the damper and a knuckle during assembly. A guide body is disposed at an opposite side of the adjuster plate from the damper, and a shim is configured for insertion between the adjuster plate and the guide body. Insertion of the shim causes the adjuster plate to change the relative orientation between the damper and the knuckle. A biasing device is configured to bias the guide body toward the damper and thereby fix the shim between the guide body and the adjuster plate, such that applying a force to the guide body that is greater than the biasing force of the spring in a direction opposite to the biasing force of the spring enables the shim to be removed from between the guide body and the adjuster plate.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
(14) A few inventive aspects of the disclosed embodiments are explained in detail below with reference to the various figures. Exemplary embodiments are described to illustrate the disclosed subject matter, not to limit its scope, which is defined by the claims. Those of ordinary skill in the art will recognize a number of equivalent variations of the various features provided in the description that follows.
I. Exemplary Suspension Components for a Vehicular Wheel
(15)
(16) The suspension components 10 can include a knuckle 18 and a damper 20, which together form a strut. In some embodiments, the strut is attached to sections of the vehicle, including but not limited to vehicular structural components such as elements of the vehicular frame.
(17) For example, as shown in
(18) Embodiments are intended to include or otherwise cover any method or apparatus for attaching the knuckle 18 to the frame member 22. In the embodiment shown in
(19) The strut can also be attached to the vehicle at other location(s), such as at a location adjacent an upper end of the damper 20. In the embodiment shown in
(20) The strut can also communicate with other elements of the vehicle. For example, a vehicular drive shaft 42 can be supported by bearings housed within the knuckle 18. The drive shaft 42 can extend through an aperture defined in the knuckle 18, and an aperture defined in the brake rotor 12. The drive shaft 42 can be secured at a side of the brake rotor 12 opposite the knuckle 18 to hold the assembly together.
(21) The damper 20 can include a number of separate sub-components. For example, the damper 20 can include an elongated cylinder 44 that extends generally perpendicular to an axis of the drive shaft 42. The cylinder 44 can extend within another outer cylinder (not shown), which itself is disposed within a flexible cover 46. Seals (not shown) may be provided between the cylinder 44 and the outer cylinder, and a piston and fluid may extend within the cylinder 44. A spring 48 may extend along the exterior of the flexible cover 46, and be held in place longitudinally by a shoulder 50 at a bottom end, and another structure at an upper end, such as the lower mounting plate 38. In the embodiment shown in
(22) The elements discussed above cooperate to facilitate the damping operation of the damper 20. However, these elements are merely discussed above for exemplary purposes, and embodiments are intended to include or otherwise cover any type of damper or damping mechanism.
(23) The damper 20 includes a damper flange 52 at its lower end that is configured for attachment to the knuckle 18. Embodiments are intended to include or otherwise cover any methods and apparatus for connecting the damper 20 to the knuckle 18. In the embodiment shown in
(24) In many applications, the strut is assembled, and then attached to the vehicle (such as at the locations discussed above) in the assembled condition. However, embodiments are intended to include or otherwise cover other alternative manufacturing techniques. In either case, the ultimate orientation of components of the strut, such as the relative orientation between the damper 20 and the knuckle 18 (which ultimately impacts the relative orientation between the damper 20 and other vehicular components, such as a line perpendicular to the drive shaft), may be relevant to certain characteristics of the vehicle. For example, as disclosed above, camber may be relevant to the design of vehicular suspension and steering systems, and may affect handling qualities of a particular suspension design, especially in the context of steering suspension components.
(25) The camber may be measured or otherwise determined based on any known, related art or later developed techniques. In some embodiments, the camber is determined by comparing a damper angle line 56, which extends along a direction of elongation of the damper 20 (or components thereof, such as the cylinder 44), to a hub reference line 58, which extends along a vertical diameter of the brake rotor 12 (or perpendicular to the drive shaft 42). No camber would occur if the damper angle line 56 and the hub reference line 58 are parallel. In configurations where either positive or negative camber is defined, the magnitude of the angle determines that amount of camber.
(26) The above suspension components 10 (strut) are merely discussed for exemplary purposes, and embodiments are intended to include or otherwise cover other known, related art, or later developed struts. In fact, some embodiments are directed to orientations of vehicular components that are not related to struts. Still further, some embodiments are directed to orienting components that are unrelated to vehicles.
II. Overall Adjustable Locator Assembly
(27)
(28) In some embodiments, the jig 60 is fixed, and used to attach the damper 20 to the knuckle 18. The camber (which can be measured as disclosed above) can be dictated based on how the jig 60 is used to attach the damper 20 to the knuckle 18. For example, the adjustable locator assembly 62, which is directed or indirectly connected to the jig 60, can be used to set the camber as the damper 20 is attached to the knuckle 18.
(29) The adjustable locator assembly 62 can include several separate components. For example, a movable plate or adjuster plate 66 can form a distal end of the adjustable locator assembly 62 adjacent the damper 20. In some embodiments, the adjuster plate 66 contacts the mounting flange 32 that is ultimately used to attach an upper section of the damper 20 to the vehicle. As discussed in more detail below, contacting the mounting flange 32 enables the adjuster plate 66, and thereby the adjustable locator assembly 62, to orient the damper 20 relative to the knuckle 18 so as to set the camber.
(30) As shown in
(31) Embodiments are intended to be usable with any type or number of shims 70, or as indicated above without any shim 70 at all. In some embodiments, only a single shim 70 is installed in the adjustable locator assembly 62 at a time, and thus one or more alternative shims of varying widths provide the adjustability disclosed above. Alternatively, in other embodiments, multiple shims 70 can be installed in the adjustable locator assembly 62 at a time. Adjustability can therefore be provided by adding or removing a number of shims to provide the desired camber, and these multiple shims 70 can all share the same width, have different widths, or be a combination thereof.
(32) The adjuster plate 66 includes a pair of bolts 72 that extend from, and in a direction perpendicular to, a surface of the adjuster plate 66 facing away from the damper 20. The bolts can be initially formed separately from the adjuster plate 66 and attached thereto by any known, related art or later developed method or apparatus, such as via welding, or alternatively can be integrally or unitarily formed with the adjuster plate 66. Only a single bolt 72 is shown in the perspective of
(33) The bolts 72 are elongated and sized in their directions of elongation to extend along the entire lateral width of the adjustable locator assembly 62. Thus, the bolts 72 extend through apertures in the guide body 64 and traverse the entire lateral width thereof, such that the bolts 72 project from a surface of the guide body 64 that faces away from the damper 20.
(34) A stopper plate 68 is adjacent to, but spaced from, the guide body 64 in a lateral direction away from the damper 20. Thus, the guide body 64 is disposed between the stopper plate 68 and the shim 70. The bolts 72 extend through apertures defined in the stopper plate 68, and are sized to traverse the entire lateral width of the stopper plate 68 so as to project from a surface of the stopper plate 68 facing away from the damper 20. The apertures and diameters of the bolts 72 are sized to that the stopper plate 68 is retained at a predetermined location on the longitudinal length of the bolts 72. The stopper plate 68 is thereby fixed at a predetermined spacing from the adjuster plate 66 from which the bolts 72 extend.
(35) Ends of the bolts 72 that project from the surface of the stopper plate 68 facing away from the damper 20 are threaded to accommodate nuts 76 for insertion thereon. For example, the nuts 76 can be screwed onto the threaded ends of the bolts 72 to secure the stopper plate 68 at the predetermined location disclosed above.
(36) A spring 74 is disposed coaxially along each of the bolts 72, and extends between the guide body 64 and the stopper plate 68. In the embodiment shown in
(37) The springs 74 are configured and disposed so as to provide a tension force between the stopper plate 68 and the guide body 64. As disclosed above, the stopper plate 68 is fixed on the bolts 72, and is thereby immobile relative to the adjuster plate 66. Because the stopper plate 68 is immobile relative to the adjuster plate 66, the tension force of the springs 74 applies a force to the guide body 64 urging the guide body 64 toward the damper 20. Thus, the springs 74 force the guide body 64 into contact with the shim 70, and the shim 70 into contact with the adjuster plate 66. The springs 74 thereby maintain the shim 70 in contact with the adjuster plate 66 on one side and the guide body 64 on the opposite side.
(38) The adjustable locator assembly 62 thereby enables shims 70 to be inserted and held in place between the adjuster plate 66 and the guide body 64, and the shims 70 can also be removed from this location. Addition and removal of the shims 70 enables the relative orientations of the damper 20 and the knuckle 18 to be adjusted, without detaching the adjustable locator assembly 62 from the jig 60 or performing other adjustments to the jig 60.
(39) In other words, the insertability and removability of the shims 70 enables the camber to be adjusted on the fly, and thereby avoids, minimizes or reduces an assembly line shut down. Camber adjustments can thereby be performed via a relatively simple, efficient, and/or time efficient manner, which may enhance the flexibility of the press equipment.
(40) The elements are disclosed above for exemplary purposes, and embodiments are intended to include or otherwise cover other configurations. For example, any number of bolts 72 (including a single bolt 72) can be used to maintain the stopper plate 68 at a fixed spacing from the adjuster plate 66. In fact, embodiments are intended to include any structure for holding the stopper plate 68 in place at a sufficient distance from the adjuster plate 66.
(41) In addition, all of the embodiments do not necessarily include springs 74 disposed between the stopper plate 68 and the guide body 64. For example, embodiments are intended to include or otherwise cover any methods or apparatus for urging the guide body 64 toward the damper 20 and thus into contact with the shim 70, and the shim 70 into contact with the adjuster plate 66.
(42) Embodiments are intended to cover still other modifications to the exemplary embodiment shown in
(43) However, the modifications are disclosed above for exemplary purposes, and embodiments are intended to cover other alternative structures.
III. Adjustable Locator Assembly Components
A. Guide Body
(44)
(45) As shown in
(46) The recessed portion 78 and the flange 80 are configured to accept the shim 70, and/or the adjuster plate 66 in lieu of the shim 70. For example,
(47) As shown in
(48) In some embodiments, the bolt receiving holes 86 are sized to fit snugly around circumferential exterior surfaces of the bolts 72. The snug fitting further impedes or prevents adjustments in the spacing between these elements in the directions indicated above, such as in the longitudinal direction.
(49) The guide body 64 can include other features that may be beneficial. For example, the guide body 64 can include a pair of mounting holes 88 that facilitate mounting the guide body 64 to another element, such as the jig 60. The mounting holes 88 can be disposed and configured to enable mounting bolts or other fasteners to extend therethrough and thereby secure, either directly or indirectly, the guide body 64 to the jig 60. However, embodiments are intended to include or otherwise cover any methods or apparatus for attaching the guide body 64 to the jig 60. In fact, in some embodiments, the guide body 64 is not secured to the jig 60 and is instead secured to another element. Still further, in other embodiments, the guide body 64 is not secured to the jig 60, and instead another element of the adjustable locator assembly 62 is secured to the jig 60 and/or to another stabilizing member.
(50)
(51) Similarly with the guide body 64 of
B. Adjuster Plate
(52)
(53) The end portions of the bolts 72 that are spaced from the adjuster plate 66 are threaded and thereby define threaded end portions 90. The threaded end portions 90 extend a sufficient distance along the longitudinal length of the bolts 72, and are otherwise configured and disposed, so as to communicate with the nuts 76 (shown in
(54) The diameter of each of the threaded end portions 90 is smaller than a diameter of each of the non-threaded adjacent sections of the bolts 72 so as to retain the stopper plate 68. For example, the diameter of each of the threaded end portions 90 is sufficiently small so as to extend through apertures 92 defined in the stopper plate 68. However, the diameter of each of the non-threaded adjacent sections of the bolts 72 is too large to extend through the apertures 92 of the stopper plate 68, and thus the stopper plate 68 is held on the bolts 72 at a location of the threaded end portions 90 that is closest to the damper 20. In other words, the stopper plate 68 is secured at a location of the bolts 72 where the threaded end portions 90 meet the non-threaded adjacent sections.
C. Stopper Plate
(55)
(56) The stopper plate 68 is configured and disposed to enable the springs 74 to be held in place around the bolts 72, such that each of the springs 74 is coaxial with one of the bolts 72. For example, one end of each of the springs 74 abuts a surface of the stopper plate 68, while an opposite end of each of the springs 74 abuts a facing surface of the guide body 64. The springs 74 thereby apply a compressing force to the guide body 64 to thereby bias or otherwise push the guide body toward the damper 20, and in particular into contact with the shim 70 or the adjuster plate 66 (in lieu of the shim 70). Importantly, insertion and removal of the shims 70 is facilitated by the user's ability to move the guide body 64 against the compressive force of the springs 74, to thereby increase the amount of space available between the guide body 64 and the adjuster plate 66.
D. Shim
(57)
(58) As shown in
(59) The shim 70 can also include a tab 96 disposed at an opposite side of the shim 70 from the open ends of the channels 94. The tab 96 can be disposed at approximately a longitudinal midpoint of the shim 70 and otherwise configured to facilitate manual insertion and/or removal of the shim 70 from the adjustable locator assembly 62. In other words, the tab 96 is configured to enable a user to grasp the tab 96, and thereby manually move or otherwise orient the tab 96 to be inserted in, or removed from, the adjustable locator assembly 62. Insertion and removal of the shims 70 is facilitated by the user's ability to move the guide body 64 against the compressive force of the springs 74, to thereby increase the amount of space available between the guide body 64 and the adjuster plate 66.
(60)
(61) However, the channels 194 of the alternative shim 170 are longer than the channels 94 of the shim 70 of
(62) Embodiments are intended to include or otherwise cover any other type of shim that enables the above operations to be performed, i.e., facilitates camber adjustments. For example, any type of shim can be used that is configured for insertion between the adjuster plate 66 and the guide body 64.
IV. Alternative Embodiments
(63) While certain embodiments of the invention are described above, and
(64) As indicated above, some of the embodiments are directed to methods and apparatus for orientating a damper and a knuckle to form a strut so as to facilitate adjusting camber. However, the disclosed methods and apparatus can be used to orient any components for any purpose beyond struts and even beyond vehicular applications.
(65) Some of the embodiments are directed to an adjustable locator assembly 62 that includes various sub-components, including an adjuster plate with projecting bolts, springs extending around and coaxial with the bolts, a guide body, a shim disposed between the adjuster plate and the guide body, and a stopper plate. However, embodiments are intended to include or otherwise cover adjustable locator assemblies that include additional or completely different components, but that otherwise facilitate changing the relative orientations between the damper and knuckle when they are being connected together.
(66) Embodiments are also intended to include or otherwise cover methods of using and methods of manufacturing any or all of the elements disclosed above. Various aspects of these methods can be performed with or otherwise cover processors and computer programs implemented by processors.
(67) While the subject matter has been described in detail with reference to exemplary embodiments thereof, it will be apparent to one skilled in the art that various changes can be made, and equivalents employed, without departing from the scope of the invention. All related art references discussed in the above Background section are hereby incorporated by reference in their entirety.
