Abstract
Description
- The present invention pertains to drive pin assemblies, such as might be used for securing a disc brake rotor to a hub.
- For the purpose of attaching a disc brake rotor to a wheel hub, it often is desirable to provide a series of equally spaced openings through a mounting ring on the rotor, with such openings being elongated in the radial direction. The rotor can then be attached to the hub using “drive pins” that extend through such openings. An advantage of attaching a rotor in this way is to accommodate radial expansion and contraction of the rotor as it heats and cools, respectively. A variety of different drive pin configurations currently exist. However, each has its own drawbacks, e.g., in terms of ability to securely attach the drive pin to the wheel hub, difficulty of installation, complexity, cost, size, etc.
- The present invention addresses these problems by providing drive pin assemblies, components thereof and methods for using them that can be both effective and easy to implement.
- One particular embodiment of the invention is directed to a drive pin assembly that includes: a first pin component and a second pin component, each having an engagement end that opens to an interior space and has an angled surface that extends for at least a portion of the width and a portion of the length of such first pin component; and a tightening mechanism at least partially disposed within the interior spaces of the first pin component and the second pin component, for drawing the first pin component and the second pin component closer together, where the angled surface of the first pin component matches the angled surface of the second pin component such that the first pin component and the second pin component slide both vertically and laterally along each other when drawn together.
- The foregoing summary is intended merely to provide a brief description of certain aspects of the invention. A more complete understanding of the invention can be obtained by referring to the claims and the following detailed description of the preferred embodiments in connection with the accompanying figures.
- In the following disclosure, the invention is described with reference to the attached drawings. However, it should be understood that the drawings merely depict certain representative and/or exemplary embodiments and features of the present invention and are not intended to limit the scope of the invention in any manner. The following is a brief description of each of the attached drawings.

However, it should be noted that the drive pin assemblies according to the present invention also may be used in any of a variety of other situations.
-
FIG. 1 illustrates a hub (or hat) 5 that is attached to an axle or a wheel drive assembly of a motorized vehicle (e.g., through openings 6) when in use. One of the purposes ofhub 5 is to function as a mounting element for attaching a disc brake rotor. Included inhub 5 is a ring of circular openings (or through-holes) 7, each defined by asidewall 8, for this purpose. -
FIG. 2 illustrates adisc brake rotor 10 to be attached tohub 5. A ring of openings (or through-holes) 11 are provided within a mounting section 12 (or ring) ofrotor 10. Each of theopenings 11 preferably is elongated in the radial direction and has straight sides and rounded ends.Surface 14 is the operative portion ofrotor 10, i.e., the portion that comes into contact with the brake pads (not shown) when in use. - In the preferred embodiments of the present invention, a drive pin assembly (such as any of the assemblies described below) extends through each of
circular openings 7 inhub 5 and through acorresponding opening 11 in themounting section 12. In the present embodiment, there are tenopenings 7 and tencorresponding openings 11, each being evenly spaced around a circle of the same diameter, so that the two sets of openings align with each other. However, any other number of openings (and corresponding drive pin assemblies) can be used. -
FIGS. 3 and 4 illustrated afirst component 20 of a drive pin assembly according to a representative embodiment of the present invention. In the present embodiment,pin component 20 is made of stainless steel and includes amain portion 22 having the shape of a modified cylinder, anengagement end 23 and anouter end 24.Engagement end 23 is open, defining aninterior space 25 withinpin component 20. As shown, the surface ofengagement end 23 is ridge-like and angled, with different points along this surface extending different lengths. In the present embodiment, outer end 24: (1) is enlarged compared tomain portion 22, (2) has a square rather than circular cross-section, and (3) also is open. However, it should be noted that variations are possible. For instance, in alternate embodimentsouter end 24 is hexagonal in shape or has any other shape. Whencomponent 20 is internally threaded, as in the present embodiment, it is preferable thatouter end 24 has a shape that permits it to be held in place rotationally when the mating component is being threaded into it (e.g., having an outside perimeter that can be held with a wrench or that fits into a corresponding shape withinhub 5 or having an inner impression that can accommodate an Allen wrench or similar wrench). - In addition, the
interior space 25 ofcomponent 20 preferably is substantially cylindrically shaped and extends all the way through the length ofcomponent 20, functioning as a passageway fromengagement end 23 toouter end 24. However, in alternate embodiments,outer end 24 has a continuous (or closed) surface, i.e., so that onlyengagement end 23 is open. In the preferred embodiments (discussed in greater detail below), thesurface 27 defininginterior space 25 includes threads. In other embodiments (also discussed below),surface 27 is smooth or otherwise non-threaded. -
FIGS. 5-7 illustrate asecond pin component 40, which has amain portion 42, anengagement end 43 and anouter end 44. In the preferred embodiment,main portion 42 has the shape of a modified cylinder, and bothouter end 44 andengagement end 43 are open, defining aninterior space 45 withinpin component 40 that is substantially cylindrically shaped and functions as a passageway fromouter end 44 toengagement end 43. In the current embodiment, pin component 40: (1) is provided with acollar 46 that provides greater width as compared to the rest ofmain portion 42, (2) includesflat strips 48 on its front and back surfaces, extending along its length, that match the straight side edges of theopening 11 through which it is to extend (e.g., in order to increase the contact surface area betweenpin component 40 and itscorresponding opening 11 and/or in order to facilitate proper orientation ofpin component 40 when it is installed), and (3) is made of stainless steel. However, in alternate embodiments,strips 48 are omitted and, e.g., the cross-section ofmain portion 42 is entirely circular. Preferably,collar 46 is disposed on the outer surface of themain portion 42 at a distance from itsouter end 44 that is just slightly greater than a thickness of therotor mounting section 12 in the vicinity of theopening 11 into whichcomponent 40 is to be inserted. - Similar to
pin component 20, the surface ofengagement end 43 is ridge-like and angled, with different points along such surface extending different lengths. More preferably, the surfaces of engagement ends 23 and 43 match, or are complementary with, each other, so thatpin component 20 andpin component 40 slide both vertically and laterally along each other when drawn together. -
FIG. 8 illustrates howpin components pin components FIG. 9 . As shown in the drawings, each of the surfaces of engagement ends 23 and 43 has a substantially flat and horizontal portion (23A and 43A, respectively), followed by an angled portion (23B and 43B, respectively), followed by another substantially flat and horizontal portion (23C and 43C, respectively). Because the cross-sections of themain portions pin components - As shown in
FIG. 9 , in the present embodiment theangled surfaces surfaces surface 43A is longer (e.g., in cross-section) thansurface 23A, andsurface 43C is shorter (e.g., in cross-section) thansurface 23C, preferably by the same amount, so that the diameters of themain portions main portions FIG. 9 ), just a portion of theirangled surfaces opening 7 inhub 5, the overall width of the combination ofmain portions FIG. 9 ). - Then, as
pin components angled surfaces pin components main portions FIG. 10 ), thereby tightly securing the entire drive pin assembly tohub 5. - It should be noted that the precise surface configurations of engagement ends 23 and 43 are not critical. Preferably, however, when the two components are drawn together such surfaces (or at least portions of them) are able to slide against each other in such a way that the overall width of the combination increases. Thus, for example,
angled portions angled portions main portions - Any of a variety of different tightening mechanisms can be used to draw
pin components FIG. 11 ,pin component 20 has internal threads andpin component 40 has aninterior space 45 that is configured as a cylindrical passageway extending all the way through it from itsouter end 44 to itsengagement end 43. In order to assemble and attach the pin assembly in this embodiment, the distal (threaded) end of abolt 60 is inserted through awasher 61 and into theouter end 44 ofcomponent 40, exits theengagement end 43 ofcomponent 40, enters theengagement end 23 ofcomponent 20, and then is rotated relative tocomponent 20 so that its threads mate with the internal threads ofcomponent 20. As the threads further engage,components outer end 24 ofcomponent 20 pressing against thesurface surrounding opening 7 inhub 5 and with the proximal end (enlarged head) 62 ofbolt 60 eventually coming into contact with theouter end 44 ofcomponent 40. Preferably,outer end 44 ofcomponent 40 is beveled, as shown in the drawings, and a bevel washer is placed betweenbolt head 62 andouter end 44. - When all of the pin assemblies have been installed in this manner,
rotor 10 is locked into rotational alignment withhub 5. At the same time, the space betweencollar 46 andbolt head 62 is sufficiently larger than the thickness ofrotor mounting ring 12 thatmain portion 42 ofcomponent 40 is able to freely slide within its correspondingslot 11, thereby enablingrotor 10 to expand and contract radially. - Variations on the foregoing embodiment are possible. For instance, in the preceding embodiment,
component 20 has internal threads. In alternate embodiments,component 20 is provided with a smooth internal surface, and a separate nut is used to engage with the distal (threaded) end ofbolt 60, such thatbolt 60 and the referenced nut constitute the tightening mechanism. However, in these alternate embodiments, the overall length of the drive pin assembly often will be increased, as compared with just using an internally threadedcomponent 20. - According to another alternate embodiment, the
pin component 40 is internally threaded and has an enlarged head at itsouter end 44, andpin component 20 is open at both ends and has a smooth internal passageway throughout its length, including an opening at itsouter end 24 for accepting a bolt. In other words, in this alternate embodiment the tightening mechanism essentially works in the opposite direction as compared to the embodiment discussed above. - Several different embodiments of the present invention are described above, with each such embodiment described as including certain features. However, it is intended that the features described in connection with the discussion of any single embodiment are not limited to that embodiment but may be included and/or arranged in various combinations in any of the other embodiments as well, as will be understood by those skilled in the art.
- Similarly, in the discussion above, functionality sometimes is ascribed to a particular module or component. However, functionality generally may be redistributed as desired among any different modules or components, in some cases completely obviating the need for a particular component or module and/or requiring the addition of new components or modules. The precise distribution of functionality preferably is made according to known engineering tradeoffs, with reference to the specific embodiment of the invention, as will be understood by those skilled in the art.
- Thus, although the present invention has been described in detail with regard to the exemplary embodiments thereof and accompanying drawings, it should be apparent to those skilled in the art that various adaptations and modifications of the present invention may be accomplished without departing from the spirit and the scope of the invention. Accordingly, the invention is not limited to the precise embodiments shown in the drawings and described above. Rather, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the claims appended hereto.
