Description
TITLE OF T}IE lhvl n~
Composite fiber spoke v~h;~ulAr wheel and method of making the same.
NAIIE OF lhv~n~
Albert Arthur Beyer FIELD OF TDE lhvnn~l~
The present invention relates to a composite fiber spoke vehi~lAr wheel and, in particular, a bicycle wheel.
P~ OF T~IE lhvl!n~lC
United States Patent 5,104,199 which issued to SchlAng~r in 1992 describes the history of the development of composite fiber v~hi~lAr wheels. Composite fiber bicycle wheels were introduced in an attempt to reduce aerodynamic drag. The early versions of these wheels were in the form of solid discs. They were fabricated by wrapping fiber reinforced cloth around a bladder. This assembly was then treated with resin and placed within a mold. ~eat and ~les~ule was applied within the mold to cure the resin.
The Schlanger reference notes that these disc wheels compromised rider stability and safety, as they were susceptible to cross winds. The SChl Anqer reference, therefore, proposes an alternative construction that has spokes. The S~hl Anq~r wheel has two integrally ~oined wheel portions with a hub retained between the wheel portions. The wheel has an outside circular member which forms an enclosed continuous, circumferential hollow annulus for supporting an annular rim. Spokes extend between the hub and the annular rim.
A disadvantage of the Schlanger reference is that it relies upon a structural adhesive to maintain the hub in position. There have been numerous failures at the hub as a result of the torsional load upon the wheel PY~PP~i ng the holding ability of the structural adhesive. United States Patent 5,452,945 which issued in 1995 to Schlanger ~icclospc an alternative means to structural adhesive for secllring the hub in position. An circular member is integrally formed with and encircles the hub. The spokes are secured to the circular member by multiple threaded fasteners that extend through the circular member and are held in position by nuts.
SUMMARY OF ThE lhv~n.1~
What is required is an alternative composite fiber spoke vPhirlllAr wheel and a method of making the same.
According to one aspect of the present invention there is provided a method of making a composite fiber spoke v~hic~ r wheel: Firstly, provide a hub, a rim, and some composite fiber strips. The composite fiber strips each having opposed ends.
Secondly, wrap each strip around a portion of the hub and secure the opposed ends to the rim. Cure the composite fiber strips, whereby the composite fiber strips serve as spokes.
According to another aspect of the present invention there is provided a composite fiber spoke vphic~ r wheel which in~ Pfi a hub, a rim, and composite fiber strip spokes.
Composite fiber strip spokes are wrapped around a portion of the hub with opposed ends o~ the composite fiber strip spokes secured to the rim.
The wrapping of the composite fiber strips around the hub, as described above, iB an ;nPYpPn~ive manner of avoiding hub failure. The strips may extend either radially or tangentially from the hub.
Although bPnPf;CiAl results may be obtained through the use of the invention, as described above, even more bPn~finiAl results may be obtained when the hub has end flanges with a plurality of slots. This enables the composite fiber strips to be extended through the slots and then wrapped around a portion of the hub.
Although hPnPfi~iAl results may be obtained through the use of the invention, as described above, there are bonding and differential PYpAn~inn problems associated with using dissimilar materials. Even more bPnPfiniAl results may, therefore, be obtained when the rim and hub are made of composite fiber and resin.

TT,~n r.lON OF THE l~rrnr~l~ EMBODIMENT
The preferred ~ , a composite fiber spoke v~h;~nl~r wheel generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 5.
Referring to FIGURES 1, composite fiber spoke v~h;c~lAr wheel 10 has a hub 12, a rim 14, and composite fiber strip spokes 16. Composite fiber strip spokes 16 wrap around a portion of hub 12, as will hereinafter be further described, with opposed ends 18 of composite fiber strip spokes 16 secured to rim 14.
The preferred method of making composite fiber spoke vehicular wheel 10, ;n~ the following steps. Firstly, referring to FIGURE 2, provide hub 12 having end flanges 20 with a plurality of slots 22. Secondly, referring to FIGURE
1, provide rim 14. Thirdly, provide some composite fiber strips 16. Composite fiber strips may either have their fibers oriented longitll~; n~ lly or may be braided. It has been found that braided strips are to be preferred. When the fiber strips are braided they do not kink as they are wrapped around hub 12.
The angle of the braid depends upon the strength requirements.
When the fibers that make up the braid approach a 45 degree angle the braid has increased torsional strength. When the fibers that make up the braid approach a 30 degree angle, some torsional strength is sacrificed in favour of greater tensile strength. Each of strips 16 has opposed ends 18. Thirdly, weave each strip 16 through one of slots 22 and around a portion of hub 12, as best illustrated in FIGURE 5. Secure opposed ends 18 of each strip 16 to rim 14. Fourthly, applying heat to cure composite fiber strips 16, whereby composite fiber strips 16 become spokes.
Composite fiber spokes 16 can extend either radially from hub 12 as illustrated in FIGURE 4 or tangentially from hub 12, as illustrated in FICUR~ 3. It is preferred that both rim 14 and hub 12 be made of composite fiber.
It will be apparent to one skilled in the art that ~;f~cations may be made to the illustrated: '-'i L without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
