Non-pneumatic resilient tire

A non-pneumatic tire having a bearing structure, extending circumferentially about an axis of rotation and including a radially inner wall and a radially outer wall defining therebetween, at least partially, an inner cavity of revolution, and a tread carried by the radially outer wall of the bearing structure, said bearing structure comprising:

• a zone of attachment on the radially inner wall for connecting the bearing structure to means of connection to a hub, said zone of attachment being located axially between the axial outer limits of the radially inner wall and having an axial sides separated by a distance not greater than 50% of the axial distance between the axially outer limits of the bearing structure;
• a plurality of support elements aligned substantially crosswise to the circumferential direction and extending in the crosswise direction, in the radially inner wall, from at least the axial sides of the zone of attachment towards the axially outer ends of the radially inner wall and, in the radially outer wall, from one axial end thereof to the other, said support elements being circumferentially juxtaposed and distributed all around the circumference of the bearing structure, each support element including a bundle of superimposed resilient base pieces, separated by a layer of elastomer adhering to each of the base pieces, so as to form a beam capable of undergoing bending stress and flexing radially at least along a part of its crosswise length when the tire is loaded;
• the radially inner and outer walls of the bearing structure being integrated with each other by a zone of lesser bending strength, each support element of the radially inner wall extending at least from a lateral end thereof to said zone of attachment, so that the zones of lesser bending strength between the radially inner and outer walls of the bearing structure parts are, under the effect of the working stresses, radially mobile in relation to the zone of attachment;
• and
• an interconnecting structure interconnecting portions of the support elements in at least the radially outer wall and arranged so that a portion of a radial stress of a support element is transferred to the circumferentially adjacent support elements, while allowing differences in displacement between adjacent support elements.
