Abstract
The invention relates to a spoke wheel that includes a peripheral rim, a central hub, and individual connecting spokes between the rim and the hub. In their free state, the spokes of the wheel are mounted without tension or compression between the rim and the hub, and each spoke can bear a compression load of at least 60 daN without bowing. Furthermore, the wheel includes a play-free connection or bilateral connection device for connecting at least one end of each spoke to the rim or the hub.
Claims25
A spoked wheel comprising:
- a peripheral rim;
- a central hub;
- a plurality of spokes assembled without tension or compression in a free state with no load on the wheel, said plurality of spokes extending length-wise between the rim and the hub;
- each of said spokes of said plurality of spokes being structured and arranged to withstand a compressive load of at least 60 daN without buckling;
- each of said spokes of said plurality of spokes comprising a first end and a second end;
- a device for play-free connection, of at least one of said first and second ends of each of said spokes of said plurality of spokes to the rim or to the hub, said play-free connection device of each of the spokes being a bi-directional connection device structured and arranged for preventing play length-wise along the spokes.
A spoked wheel comprising:
- a peripheral rim;
- a central hub;
- a plurality of spokes assembled without tension or compression in a free state with no load on the wheel, said plurality of spokes extending length-wise between the rim and the hub;
- each of said spokes of said plurality of spokes being structured and arranged to withstand a compressive load of at least 60 daN without buckling;
- each of said spokes of said plurality of spokes comprising a first end and a second end;
- a device for play-free connection of said first end of each respective spoke to one of the rim and hub for preventing play length-wise along each respective spoke;
- said second end being fixed to another of the rim and hub with glue.
A spoked wheel comprising:
- a peripheral rim;
- a central hub;
- a plurality of spokes assembled without tension or compression in a free state with no load on the wheel, said plurality of spokes extending length-wise between the rim and the hub;
- each of said spokes of said plurality of spokes being structured and arranged to withstand a compressive load of at least 60 daN without buckling;
- each of first and second ends of each of the spokes is either a free end or a threaded end.
A spoked wheel comprising an assembly of a rim, a hub, spokes extending between the rim and the hub, and longitudinally adjustable connections between respective ones of the spokes and at least one of the rim and the hub, said spokes being structured and arranged to withstand a net compressive load of at least 60 daN without buckling, said wheel being made by a method comprising the following:
- assembling the spokes to the rim and to the hub;
- said assembling of the spokes to the rim and the hub comprising setting the longitudinally adjustable connections to provide a longitudinal load level in the spokes with neither tension nor compression in a free state with no load on the wheel.
A method of assembling a non-tensioned spoked bicycle wheel, said wheel comprising a rim, a hub, and spokes extending between the rim and the hub, said method comprising:
- obtaining at least ten spokes, each of the spokes having a single predetermined length extending between a first end and second end, each of the spokes being structured and arranged to withstand a net compressive load of at least 60 daN applied longitudinally along each said spoke without buckling;
- connecting all of the spokes to one of the hub and rim by inserting the first ends of all of the spokes into respective openings or housings of said one of the hub and rim;
- connecting all of the spokes to another of the hub and rim by inserting the second ends of all of the spokes into respective openings or housings of said another of the hub and rim;
- setting a longitudinal load level in each of the spokes in a free state, connected between the hub and rim with no load on the wheel, to be zero tension and zero compression;
- fixing all of the first ends of the spokes to said one of the hub and rim with glue.
