Abstract

A method of making a wheel assembly using hybrid spokes that combines a synthetic fiber cable with an outer rod segment connected to a rim and an inner rod segment connected to a hub. An anchor is used to connect each end of the fiber cable to a length of conventional rod, preferably through the use of a swaging operation. Each rod segment includes a standard end feature on its free end—such as a threaded shaft or J-bend. The hybrid assembly can preferably be retrofitted to applications that now use a conventional rod or wire. This allows synthetic fiber cables—with their unique mechanical properties—to be incorporated in existing designs.

First claim

Having described my invention, I claim:

1 . A method for making a wheel assembly, comprising:
(a) providing a plurality of hybrid spokes, with each of said hybrid spokes being made by,
(i) providing a synthetic cable, having an outer end and an inner end,
(ii) providing an outer anchor and an inner anchor,
(iii) creating a synthetic cable assembly by attaching said outer anchor to said outer end of said synthetic cable and attaching said inner anchor to said inner end of said synthetic cable,
(iv) providing an inner rod segment having an outer end and an inner end,
(v) providing an outer rod segment having an outer end and an inner end,
(vi) after attaching said inner anchor to said synthetic cable, swaging said inner anchor to said outer end of said inner rod segment,
(vii) after attaching said outer anchor to said synthetic cable, swaging said outer anchor to said inner end of said outer rod segment;
(b) providing a hub; (c) providing a rim; and (d) lacing said plurality of hybrid spokes between said hub and said rim.

2 . The method for making a wheel assembly as recited in claim 1 , further comprising for each of said hybrid spokes:
(a) bedding said synthetic cable assembly before swaging said inner anchor to said outer end of said inner rod segment; and (b) bedding said synthetic cable assembly before swaging said outer anchor to said inner end of said outer rod segment.

3 . The method for making a wheel assembly as recited in claim 2 , further comprising for each of said hybrid spokes:
after bedding said synthetic cable assembly adjusting a length of said swaged connection between said inner anchor and said inner rod segment in order to adjust an overall length for said hybrid spoke.

4 . The method for making a wheel assembly as recited in claim 2 , further comprising for each of said hybrid spokes:
after bedding said synthetic cable assembly adjusting a length of said swaged connection between said outer anchor and said outer rod segment in order to adjust an overall length for said hybrid spoke.

5 . The method for making a wheel assembly as recited in claim 3 , further comprising for each of said hybrid spokes:
after bedding said synthetic cable assembly adjusting a length of said swaged connection between said outer anchor and said outer rod segment in order to adjust an overall length for said hybrid spoke.

6 . The method of making a wheel assembly as recited in claim 2 wherein said bedding includes applying tension until said synthetic cable assembly reaches a stable length.

7 . The method of making a wheel assembly as recited in claim 1 wherein said connections between said anchors and said synthetic cable are made by potting.

8 . A method for making a wheel assembly, comprising:
(a) providing a plurality of hybrid spokes, with each of said hybrid spokes being made by,
(i) providing a synthetic cable, having an outer end and an inner end,
(ii) providing an outer anchor and an inner anchor,
(iii) creating a synthetic cable assembly by attaching said outer anchor to said outer end of said synthetic cable and attaching said inner anchor to said inner end of said synthetic cable,
(iv) providing an inner rod segment having an outer end and an inner end,
(v) providing an outer rod segment having an outer end and an inner end,
(vi) after attaching said inner anchor to said synthetic cable, creating an inner swaged connection between said inner anchor and said outer end of said inner rod segment,
(vi) after attaching said outer anchor to said synthetic cable, creating an outer swaged connection between said outer anchor and said inner end of said outer rod segment;
(b) providing a hub; (c) providing a rim; and (d) lacing said plurality of hybrid spokes between said hub and said rim.

9 . The method for making a wheel assembly as recited in claim 8 , further comprising for each of said hybrid spokes:
(a) bedding said synthetic cable assembly before attaching said inner anchor to said outer end of said inner rod segment; and (b) bedding said synthetic cable assembly before attaching said outer anchor to said inner end of said outer rod segment.

10 . The method for making a wheel assembly as recited in claim 9 , further comprising for each of said hybrid spokes after bedding said synthetic cable assembly adjusting a length of said inner swaged connection between said inner anchor and said inner rod segment in order to adjust an overall length for said hybrid spoke.

11 . The method for making a wheel assembly as recited in claim 9 , further comprising for each of said hybrid spokes after bedding said synthetic cable assembly adjusting a length of said outer swaged connection between said outer anchor and said outer rod segment in order to adjust an overall length for said hybrid spoke.

12 . The method for making a wheel assembly as recited in claim 8 , wherein:
(a) a first coupler is used to make said inner swaged connection between said inner anchor and said outer end of said inner rod segment; and (b) a second coupler is used to make said outer swaged connection between said outer anchor and said inner end of said outer rod segment.

13 . The method of making a wheel assembly as recited in claim 9 wherein said bedding includes applying tension until said synthetic cable assembly reaches a stable length.

14 . The method of making a wheel assembly as recited in claim 8 wherein said connections between said anchors and said synthetic cable are made by potting.

15 . A method for making a wheel assembly, comprising:
(a) providing a plurality of hybrid spokes, with each of said hybrid spokes being made by,
(i) providing a synthetic cable, having an outer end and an inner end,
(ii) providing an outer anchor and an inner anchor,
(iii) creating a synthetic cable assembly by attaching said outer anchor to said outer end of said synthetic cable and attaching said inner anchor to said inner end of said synthetic cable,
(iv) bedding said synthetic cable assembly in order to create a stable synthetic cable assembly length,
(v) providing an inner rod segment having an outer end and an inner end,
(vi) providing an outer rod segment having an outer end and an inner end,
(vii) after attaching said inner anchor to said synthetic cable, attaching said inner anchor to said outer end of said inner rod segment,
(viii) after attaching said outer anchor to said synthetic cable, attaching said outer anchor to said inner end of said outer rod segment,
(ix) wherein said stable synthetic cable assembly length, said attachment between said inner anchor and said inner rod segment, and said attachment between said outer anchor and said outer rod segment are used to create a desired overall length for said hybrid spoke;
(b) providing a hub; (c) providing a rim; and (d) lacing said plurality of hybrid spokes between said hub and said rim.

16 . The method of making a wheel assembly as recited in claim 15 wherein said connections between said anchors and said synthetic cable are made by potting.

17 . The method of making a wheel assembly as recited in claim 15 wherein said attachment between said inner anchor and said inner rod segment is made by swaging.

18 . The method of making a wheel assembly as recited in claim 15 wherein said attachment between said outer anchor and said outer rod segment is made by swaging.

19 . The method of making a wheel assembly as recited in claim 15 wherein said inner rod segment has a standard end fitting.
