Abstract

"PNEU AUTO-SUSTENTáVEL PARA RODAS DE VEìCULOS E MéTODO DE FABRICAR O MESMO". Um pneu auto-sustentável para rodas de veículos compreende uma estrutura de carcaça (2) tendo pelo menos uma camada de carcaça (3a, 3b) munida de abas extremas (19, 21) em relação de acoplamento com respectivas estruturas de reforço anular (4) dispostas em relação coaxial com um eixo de rotação geométrico do pneu em posições axialmente mutuamente espaçada e cada uma compreendendo pelo menos uma primeira camada intermediária anular circunferencialmente inextensível (5a); uma estrutura de cinta (6) aplicada à estrutura de carcaça (2) em uma posição radialmente externa da mesma; uma banda de rodagem (9) aplicada em uma posição radialmente externa à estrutura de cinta (6) e um par de costados (10) aplicados à estrutura de carcaça (2) em posições lateralmente opostas. O pneu auto-sustentável compreende pelo menos uma camada intermediária de enrijecimento elástico (11) disposta em pelo menos um dos costados (10) e tendo uma parte extrema radialmente interna (15) disposta pelo menos parcialmente em relação axial lado a lado contra a primeira camada intermediária de ancoragem anular (5a).
