Abstract:
1. A non-pneumatic resilient wheel, that defines three perpendicular directions, circumferential, axial and radial, said wheel comprising: a hub; an annular band referred to as a shear band comprising at least one inner circumferential membrane and one outer circumferential membrane that are oriented in the circumferential direction; and a plurality of support elements that connect the hub to the inner circumferential membrane, wherein the two membranes are connected to one another by means of a series, that extends in the circumferential direction, of cylinders referred to as connection cylinders, said connection cylinders being non-touching in the circumferential direction, and a generatrix of each cylinder is oriented in the axial direction; wherein the connection cylinders are composite cylinders comprising fibres embedded in a resin matrix, wherein an average distance d, measured in the circumferential direction between two consecutive connection cylinders is such that the ratio d/D is between 0.10 and 0.50, where D is a diameter of the cylinders, wherein at least a portion of the connection cylinders are reinforced by a reinforcing element referred to as a “radial cylinder reinforcement” that passes through them completely along their diameter, parallel to the radial direction, and wherein the radial cylinder reinforcement is formed by a series of discrete radial reinforcements oriented parallel to the radial direction, said series of reinforcements being aligned along the axial direction.
