Abstract:
A non-pneumatic tire includes an inner circumferential barrier configured to be coupled to a hub, an outer circumferential barrier radially spaced from the inner circumferential barrier, and a support structure extending between the inner circumferential barrier and the outer circumferential barrier and coupling the inner circumferential barrier to the outer circumferential barrier. The support structure includes a plurality of ribs extending between the inner circumferential barrier and the outer circumferential barrier. The support structure at least partially defines a first axial side of the tire and a second axial side of the tire opposite the first axial side of the tire. The first and second axial sides of the tire define an axial width of the support structure. The axial width of the support structure varies as the support structure extends between the inner circumferential barrier and the outer circumferential barrier.
Abstract:
This invention relates generally to shear band of a tire that has means for inducing buckling when the tire is subjected to high deformations, and, more specifically, to a tire that has a shear band with at least one membrane that has a reinforcement having predetermined configurations for controlling the buckling behavior of the reinforcement when the membrane is subjected to compressive stress.
Abstract:
An underground mine tire 20 having a nominal bead diameter of 20.0 inches or less has a carcass, a tread 25 and a pair of rubber sidewalls 23, each extending along the outer periphery of the carcass 21 below the tread 25. The tire 20 has a nominal bead width D greater than 8.50 inches and an overall diameter of less than 55 inches. The carcass 21 has at least one radial steel cord reinforced ply 24.
Abstract:
The present invention provides a shock absorber loaded in the inner cavity of a tire enclosed by a tire for a two-wheeler and a rim, which exhibits suitable hardness when starting running and is excellent in cushioning property, both when starting running and during running, due to decrease in hardness as the temperature increases while running. Specifically, the present invention relates to a shock absorber which is loaded in the inner cavity of a tire enclosed by a tire for a two-wheeler and a rim and contacts substantially with the entire inner surface of a tire to be compressed, is circular in the tire circumferential direction and has closed cells; the shock absorber comprising an expanded rubber composition containing at least 5 parts by weight of an organic polymer having a softening point of at least 40° C., based on 100 parts by weight of a rubber component.
Abstract:
Disclosed is a self-supporting tire for wheels for bicycles, motorcycles and the like comprising an outer surface layer (5), which establishes contact with the ground (8) and an inner supporting layer (6) realized by a flexible polyurethane elastomer with a cellular structure, which at least partially occupies the internal volume of the tire (1) and supports the outer surface layer, also comprising a flexible membrane (9) substantially having the shape of the outer layer (5) and radially compressing the inner supporting layer (6).
