FIELD: transport.SUBSTANCE: invention relates to automotive industry, in particular, to design of polyurethane auto-tires with resilient spokes. The auto-tire is made with resilient spokes of elastic polyurethane interconnecting thickness-variable at inner side outer ring with tread and inner ring fixed on metal rim of wheel. Thereat, the inner ring is made variable in its thickness and at the outer side of the ring, with increase of this thickness from spokes to midpoints of wheel parts located in spaces between spokes.EFFECT: decrease in mass and uniformity of radial stiffness along perimetre of auto-tire tread.1 dwg |
