Abstract

Enveloppe déformable sans air à support structurel (1) pour un objet roulant poussé ou tiré à une vitesse inférieure à 25 km/h, ou pour une roue folle d’un véhicule dont la vitesse maximale est inférieure à 25 km/h, comprenant une bande annulaire (2) de roulage destinée à rouler sur un sol, une pluralité de rayons (3) s’étendant transversalement et radialement à l’intérieur de la bande annulaire (2) de roulage. La bande annulaire (2) de roulage a des modules élastiques circonférentiel et transverse au moins égaux à 1 MPa et au plus égaux à 100 MPa. Les rayons (3) reliant la bande annulaire de roulage à la jante ont des modules élastiques radial et transverse au moins égaux à 1 MPa et au plus égaux à 100 MPa. Figure d’abrégé : Figure 1Airless deformable envelope with structural support (1) for a rolling object pushed or pulled at a speed less than 25 km/h, or for an idler wheel of a vehicle whose maximum speed is less than 25 km/h, comprising a annular rolling belt (2) intended to roll on a ground, a plurality of spokes (3) extending transversely and radially inside the annular rolling belt (2). The annular rolling belt (2) has circumferential and transverse elastic moduli at least equal to 1 MPa and at most equal to 100 MPa. The spokes (3) connecting the annular rolling strip to the rim have radial and transverse elastic moduli at least equal to 1 MPa and at most equal to 100 MPa. Abstract Figure: Figure 1
