NON-PNEUMATIC TIRE

摘要

A structural supported tire includes a ground contacting tread portion (105) , a reinforced annular band (110) disposed radially inward of the tread portio n, and a plurality of web spokes (150) extending transversely across and radial ly inward from the reinforced annular band and anchored in a wheel or hub. The reinforced annular band comprises an elastomeric shear layer (120), at least a first membrane (130) adhered to the radially inward extent of the elastomeri c shear layer and at least a second membrane (140) adhered to the radially outward extent of the elastomeric shear layer. Each of the membranes has a longitudinal tensile modulus sufficiently greater than the shear modulus of the shear layer so that when under load the ground contacting portion of the tire deforms to a flat contact region through shear strain in the shear laye r while maintaining constant the length of the membranes, the web spokes transmitting load forces between the annular band and the hub through tensio n in the web spokes not connected to the ground contacting portion of the tire .
