Non-pneumatic resilient wheel (10), that is supported structurally and defines three perpendicular directions, circumferential (X), axial (Y) and radial (Z). The wheel comprises a hub (11); an annular band referred to a shear band (13) comprising at least one inner circumferential membrane (14) and one outer circumferential membrane (16) that are oriented in the circumferential direction X; and a plurality of support elements (12) that connect the hub (11) to the inner circumferential membrane (14). The two membranes (14, 16) are connected to one another, in zones (17) referred to as anchoring zones, by means of a series (15A, 15B, 15C), that extends in the circumferential direction (X), of cylinder structures (15) referred to as connecting cylindrical structures that are non-touching in the circumferential direction X. Each connecting cylindrical structure (15) comprises a plurality of elementary cylinders (15a, 15b) having their generatrix oriented along the axial direction Y, said elementary cylinders being fitted one inside the other and interconnected to one another in each anchoring zone (17). |

1. A non-pneumatic resilient wheel which defines three perpendicular directions, a circumferential direction X, an axial direction Y, and a radial direction, said wheel comprising:
a hub; an annular band referred to a shear band comprising at least one inner circumferential membrane and one outer circumferential membrane that are oriented in the circumferential direction X, the at least one inner circumferential membrane and the one outer circumferential membrane comprise glass fibres embedded in a resin matrix that are unidirectional and oriented parallel to the circumferential direction X, wherein the resin matrix is a thermosetting resin that is a vinyl ester resin; and a plurality of support elements that connect the hub to the at least one inner circumferential membrane, wherein the inner and outer membranes are connected to one another, in zones referred to as anchoring zones, via a series, that extends in the circumferential direction X, of cylindrical structures, referred to as connecting cylindrical structures, that are non-touching in the circumferential direction X, and wherein the connecting cylindrical structures are not connected together in the circumferential direction X; and wherein each connecting cylindrical structure comprises a plurality of elementary cylinders, configured as concentric cylinders, and having their generatrix oriented along the axial direction Y, said elementary cylinders being fitted one inside the other and interconnected to one another in each anchoring zone, wherein the elementary cylinders are composite cylinders comprising glass fibres embedded in the resin matrix, wherein an average distance d, measured in the circumferential direction X, between two consecutive connecting cylindrical structures is such that a ratio d/D is between 0.10 and 0.50, and wherein D is a diameter of the connecting cylinders. |
