Abstract

"PNEU AUTO-SUPORTANTE PARA RODAS DE VEìCULO, RODA COM PNEU PARA VEìCULOS, E, MéTODO PARA FABRICAR UM PNEU AUTO-SUPORTANTE PARA RODAS DE VEìCULOS". Um pneu auto-suportante (1) tem estruturas de reforço nos talões (4) que definem superfícies de apoio (4a) para um aro correspondente (1a) que tem um perfil que converge no sentido do eixo de rotação do pneu, afastado do plano equatorial X-X do próprio pneu. As lonas de carcaça (3a, 3b) são, cada uma, feitas por deposição seq³encial de seções tipo tira distribuídas circunferencialmente sobre um suporte toroidal (11). Insertos de suporte elásticos (16, 21) são interpostos entre as porções laterais (13a, 14a) de seções axialmente internas (13), seções axialmente intermediárias (15). Desta maneira, ao redor de no mínimo um de ditos insertos de suporte o grau de abertura dos quais pode ser modulado dependendo de requisitos, modificando a relação aresta/espaço vazio determinada pela distância existente entre as porções laterais (13a, 14a, 15a) das seções tipo tira (13, 14, 15) que cobrem cada um dos lados axialmente opostos do próprio inserto de suporte."SELF-SUPPORTING VEHICLE WHEEL TIRE, VEHICLE TIRE WHEEL, AND METHOD FOR MANUFACTURING A SELF-SUPPORTING VEHICLE WHEEL TIRE". A self-supporting tire (1) has bead reinforcement structures (4) that define support surfaces (4a) for a corresponding rim (1a) that has a profile that converges towards the tire's axis of rotation away from the plane. equatorial XX of the tire itself. The carcass linings (3a, 3b) are each made by sequential deposition of circumferentially distributed strip-like sections on a toroidal support (11). Elastic support inserts (16, 21) are interposed between the side portions (13a, 14a) of axially inner sections (13), axially intermediate sections (15). Thus, around at least one of said support inserts the degree of openness of which can be modulated depending on requirements, modifying the edge / void ratio determined by the distance between the side portions (13a, 14a, 15a) of the strip-like sections (13, 14, 15) covering each axially opposite side of the support insert itself.
