Title (EN) NON-PNEUMATIC WHEEL HAVING POLYAMIDE SPOKES
(FR) ROUE NON PNEUMATIQUE AYANT DES RAYONS EN POLYAMIDE
Abstract:
(EN) A non-pneumatic wheel (10, 10') includes an outer band (400), a hub (100) and a plurality of spokes (300, 300') formed from a polyamide material. Each of the plurality of spokes is mounted having a pretension in the radial direction corresponding to a displacement under the design load of the wheel, the displacement being equal to or greater than a predetermined deflection of the outer band under normal operation. The plurality of spokes is made from a polyamide material having a conditioned tensile modulus between 600 MPa and 3000 MPa, an equilibrium moisture content of no more than 1.5 %, and a fatigue failure resistance that can withstand at least 1 million cycles.
(FR) L'invention concerne une roue non pneumatique (10, 10') comprenant une bande externe (400), un moyeu (100) et une pluralité de rayons (300, 300') formés à partir d'un matériau polyamide. Chacun de la pluralité de rayons est monté avec une précontrainte dans la direction radiale correspondant à un déplacement sous la charge théorique de la roue, le déplacement étant supérieur ou égal à une déviation préétablie de la bande externe en fonctionnement normal. La pluralité de rayons est fabriquée à partir d'un matériau polyamide ayant un module d'élasticité en traction conditionné entre 600 MPa et 3000 MPa, un degré d'humidité d'équilibre inférieur ou égal à 1,5 %, et une résistance à la rupture de fatigue qui peut résister à au moins 1 million de cycles.
