Abstract
The vehicle wheel includes an outer rim hoop with means for holding a tire, a plurality of spoke portions, and a central hub assembly. The central hub assembly includes an axle assembly and a hub shell that is rotatable about the axle. The hub shell includes at least two axially spaced outer flanges for attachment with the spokes. The spokes are connected at their outer ends to the rim hoop and at their inner ends to their respective outer flange. Firm attachment between the spoke and the outer flange is achieved by engaging of a portion of the spoke with a cavity formed within at least one of the rim and the outer flange. Also disclosed are attachment arrangements that include an intermediate connection member to facilitate attachment between the spoke and the cavity.
Claims10
A wheel comprising:
- a peripheral wheel rim;
- a central hub with a central axle and an outer flange;
- a plurality of pretensioned spokes extending between the rim and hub, wherein said spokes have a first portion connected to said rim and a second portion opposed to said first portion and connected to said hub;
- a cavity formed within at least one of said outer flange and said rim for connection with at least one of said spokes, wherein the cavity is oriented axially and the spoke includes a bent region;
- wherein at least one of said first portion and said second portion of said at least one spoke is joined to at least one of said outer flange and said rim by means of a deformed engagement in a deformed engagement region, said cavity surrounding and enclosing the cross-section of said spoke at said deformed engagement region;
- and
- wherein said deformed engagement results in a connection to resist relative movement between said cavity and at least one of said first portion and said second portion of said at least one spoke at said engagement region.

A wheel, comprising:
- a peripheral wheel rim;
- a central hub with a central axle and an outer flange;
- a plurality of pretensioned spokes extending between the rim and hub, wherein said spokes have a first portion connected to said rim and a second portion opposed to said first portion and connected to said hub, further comprising means for adjusting tension in the plurality of pretensioned spokes;
- and
- a preformed cavity formed within at least one of said outer flange and said rim for connection with at least one of said spokes,
- wherein at least one of said first portion and said second portion of said at least one spoke is joined to at least one of said outer flange and said rim by means of a deformed engagement in a deformed engagement region, said cavity enclosing the cross section of said spoke at said deformed engagement region, wherein said deformed engagement region is formed by interaction between said spoke and preformed cavity wherein one of (1) the preformed cavity is deformed by the spoke and (2) the spoke is deformed by the preformed cavity;
- and
- including at least one reinforcement element contacting said at least one of said rim and said outer flange, wherein said reinforcement element serves to reinforce said at least one of said rim and said outer flange to resist stress and deflection associated with spoke tensile forces, wherein at least one of said spokes is positioned to contact said reinforcement element;
- and
- wherein said deformed engagement results in a connection to resist relative movement between said cavity and at least one of said first portion and second portion of said spoke at said deformed engagement region.

A wheel comprising:
- a peripheral wheel rim;
- a central hub with a central axle and an outer flange;
- a plurality of pretensioned spokes extending between the rim and hub, wherein said spokes have a first portion connected to said rim and a second portion opposed to said first portion and connected to said hub, further comprising means for adjusting tension in the plurality of pretensioned spokes;
- and
- a preformed cavity formed within at least one of said outer flange and said rim for connection with at least one of said spokes,
- wherein at least one of said first portion and said second portion of said at least one spoke is joined to at least one of said outer flange and said rim by means of a deformed engagement in a deformed engagement region, said cavity enclosing the cross-section of said spoke at said deformed engagement region, wherein said deformed engagement region is formed by interaction between said spoke and preformed cavity wherein one of (1) the preformed cavity is deformed by the spoke and (2) the spoke is deformed by the preformed cavity;
- and
- including at least one reinforcement element contacting said at least one of said rim and said outer flange, wherein said reinforcement element serves to reinforce said at least one of said rim and said outer flange to resist stress and deflection associated with spoke tensile forces, wherein said reinforcement element is an annular guide ring which is of a harder material than the hub flange;
- and
- wherein said deformed engagement results in a connection to resist relative movement between said cavity and at least one of said first portion and second portion of said spoke at said deformed engagement region.
