摘要： A banded radial run-flat tire (10) having a band with a dual-modulus of bending deflection behavior. Bands (36 1-6 and 36 8 ) producing various basic dual-modulus characteristics are disclosed. In one type, the band (36') has a greater resistance to bending forces tending to decrease its local radius of curvature than to those tending to flatten it. In a second type (36 6 ), bending stiffness increases with increasing stress irrespective of the bending direction. In a third type (36 8 ), a two-step modulus is demonstrated in which deflection is initially resisted at one rate and final deflection is resisted at a higher rate. Various embodiments of the band are disclosed in which the various types of dual-modulus behavior are obtained either by mechanical structural means or by internal geometry means.

摘要： @ A run-flat pneumatic tire 10 has a compression element 36 of annular structure on an inside surface 38 of the crown 22 thereof, which compression element 36 is stabilized by a multiplicity of closely spaced spoke-like radial elements 32 in the tire sidewalls 24 such that de-pressurized operation of the tire without damage is possible. The compression element 36 is a helix with closely spaced coils wound from a rod of a cross-sectional shape selected from various solid and tubular configurations. Round, square, and rectangular coil cross-sectional configurations are disclosed, as are interlocking convex/concave and tongue/groove arrangements. The helical compression element 36 is installed in the tire 10 by winding up the helix to reduce its diameter such that it can pass through bead portions 26 of the tire, or by introducing one end of an end coil of the helix over one of the bead portions 26 into the interior of the tire 10 and effecting relative rotation to feed the helix into the tire. The compression element 36 can be bonded in place and can also be preloaded by various means.

摘要： @ A banded radial run-flat pneumatic tire with a transversely segmented band (28) that varies the bending stiffness of the band circumferentially relative to the bending stiffness across the band. The band can be segmented into annular side-by-side hoop-like coaxial band elements (30) either of the same or of different diameters. An elastomer (32) bonded between adjoining circumferential edges of the band elements connects them for co-operative association to give the band its desired operating characteristics. The, elasticity of the elastomer and the spacing between the band elements can be selected to tailor the performance of the band. Preferably the bending stiffness of the band is 1000 times as great circumferentially as it is transversely across the band.
