Abstract: 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.

Abstract: A laminated product (1) that forms a deformable cellular structure, comprising: an upper band (2) and a lower band (3) both oriented in the same main direction (X); and between the two bands and connecting the latter in zones (4a, 4b) referred to anchoring zones, a series (5A, 5B, 5C) that extends in the direction X, of cylindrical structures (5) referred to connecting cylindrical structures that are non-touching in the direction X. Each connecting cylindrical structure (5) comprises a plurality of preferably concentric elementary cylinders (5a, 5b) having their generatrix oriented along an axis Y perpendicular to the direction X, said elementary cylinders being fitted one inside the other and interconnected to one another in each anchoring zone (4). Said elementary cylinders are especially composite cylinders comprising fibers embedded in a resin matrix.

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.

Abstract: A resilient wheel of a railway car includes a hub (1) with an annular projection (2) on the outer surface thereof, and a pressure disk (8), the hub and the disk being connected by bracing elements (7), and having ventilation ports (3, 9). An inner rim (4) having an annular projection (5) on the inner surface thereof is interposed between the hub (1) and the pressure disk (8). The wheel further includes resilient elements (13) some of which are reinforced and disposed between the side surfaces of the pressure disk (8) and the annular projections (2, 5) of the inner rim (4) and hub (1), while one more resilient element is disposed between the hub (1) and the inner surface of the annular projection (5) of the inner rim (4).
