Abstract
Non-pneumatic resilient wheel (10), that is supported structurally and defines three perpendicular directions, circumferential (X), axial (Y) and radial (Z), this wheel comprising: a hub (11); an annular band referred to as 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)U. The two membranes (14, 16) are connected to one another by means of a series, that extends in the circumferential direction (X), of cylinders (15) referred to as connection cylinders, said connection cylinders (15) being non-touching in the circumferential direction X and having their generatrix oriented in the axial direction Y. The connection cylinders (15) are composite cylinders comprising fibers embedded in a resin matrix.
