Tire having optimum characteristics for the ride comfort of a vehicle

摘要

A tire for a vehicle, that is representable by a dynamic rigid-ring tire model with concentrated parameters, has construction features that are substantially equivalent to concentrated parameters that fall within the following intervals corresponding to preselected indices of comfort: rb=100-300 (Ns/m) rbt=2-40 (Nms/rad) rcz=100-350 (Ns/m) rct=10-90 (Nms/rad) Ckx=18,000-70,000 (N), where rb is a radial foundation dampening of said dynamic tire model; rbt is a torsional foundation dampening of said dynamic tire model; rcz is a residual radial dampening of said dynamic tire model; rct is a residual torsional dampening of said dynamic tire model; and Ckx is a slipping stiffness of a brush model of said tread.
