摘要： A non-pneumatic tire includes a generally annular inner ring that attaches to a wheel, a generally annular outer ring, and an interconnected web between the generally annular inner ring and the generally annular outer ring. The interconnected web defines a plurality of openings circumferentially spaced around the tire and radially spaced at varying distances from an axis of rotation, so as to support a load by working in tension. The interconnected web includes a plurality of web elements having a varying thickness, including a first plurality of web elements above the axis of rotation and a second plurality of web elements below the axis of rotation. The varying thickness is configured to facilitate buckling of the interconnected web. When a load is applied, the first plurality of web elements are subjected to a tensile force while the second plurality of web elements buckle.

摘要： Provided is a tire capable of improving the wear resistance. The tire comprises: a case portion comprising: an inner cylindrical member; an outer cylindrical member surrounding the inner cylindrical member from a tire radial outer side; and a plurality of connecting members arranged between the inner cylindrical member and the outer cylindrical member and connecting the two cylindrical members; and a tread portion having a tread rubber disposed on a tire radial outer side of the outer cylindrical member, wherein: when a portion of the tread rubber located on a tire radial outer side of a junction of the connecting members joined to the outer cylindrical member is defined as a tread rubber junction, a wear resistance of a first portion of the tread rubber inclusive of the tread rubber junction is larger than a wear resistance of a second portion of the tread rubber other than the first portion.

摘要： A wheel assembly for a surface vehicle is presented. The wheel assembly comprises a tire comprising an envelope structure which by its inner surface encloses a cavity. The envelope structure comprises an outer, surface-engaging side having a circumferential surface, and opposite side walls which are integral with and extend from the surface-engaging side. The sides walls by their free ends define an inner, rim-engagement side of the tire by which the tire is connectable to a wheel hub. Each of the opposite side walls comprises a surface pattern defining a suspension assembly within the side wall to thereby prevent stretching of the tire envelope towards its maximal volume when the envelope is compressed with gas, while allowing deformation of the tire envelope when loaded or depressurized such that the surface engaging side of the tire maintains a substantially constant contact with the surface.

摘要： The invention relates to a tyre-type device for equipping a vehicle, with an improved flattening of the tread thereof compared to a standard tyre. The tyre-type device (1) comprises a radially outer revolution structure (2) which comes into contact with the ground and comprises a peripheral reinforcing ply (22), a radially inner revolution structure (3) which is coaxial to the radially outer revolution structure and used to provide the connection to an assembly means (4), an inner annular space (5) radially defined by the two revolution structures, and a carrier structure (6) at last partially connecting the two revolution structures and consisting of a plurality of carrier elements (7), pairwise independent, subjected to buckling under compression in the area of contact (A) with the ground. According to the invention, the smallest characteristic dimension E of the section S of any carrier element (7) is at the most equal to 0.02 times the average radial height H of the inner annular space (5), and the surface density D of the carrier elements (7) per surface unit of the radially outer revolution structure, expressed in 1/m
2 , is at least equal to Z/(A*∑Fr/n), where Z is the nominal radial load, expressed in N, A is the ground contact surface, expressed in m
2 , and ∑Fr/n is the breaking strength in average traction of the n carrier elements subjected to buckling under compression, expressed in N.-

摘要： An airless tire has a cylindrical tread ring 2 having a ground-contacting surface 21, a hub disposed on the radially inside of the tread ring 2 and fixed to an wheel shaft, and spokes connecting between the tread ring 2 and the hub. The tread ring 2 has a side wall 22 continued from the ground-contacting surface 21 and forming a ring side surface. The side wall 22 has a supporting portion 23 which, when the tread ring 2 alone is horizontally laid on a horizontal surface H, contacts with a horizontal surface H and supports the tread ring 2 so that a ring axis A2 is oriented in a direction perpendicular to the horizontal surface H.
