Abstract

"TAMBOR DE CONSTRUçãO DE PNEU EXPANSìVEL COM SEGMENTOS FIXOS E EXPANSìVEIS ALTERNANTES, E PERFIS PARA REFORçOS DE COSTADO". Um tambor de construção de pneu expansível, tendo segmentos fixos (226, 326, 426) e expansíveis (228, 328, 428) alternados (por exemplo, 24 de cada) em uma seção central (220, 320, 420) do tambor. Os segmentos expansíveis são extensíveis axialmente e espaçados circunferencialmente entre si e são perfilados (têm recessos ou entalhes), para acomodar componentes do pneu, tais como reforços de costado. Dois diferentes mecanismos para expansão da seção central são descritos. Um primeiro mecanismo inclui dois elementos de cunha (358), que são móveis axialmente entre si, para expandir a seção central. Os elementos de rampa (348) associados com os segmentos expansíveis (328) podem ser, desse modo, movimentados radialmente para fora. Bandas de borracha (358) proporcionam uma força de restauração, para contrair a seção central. Um segundo mecanismo inclui dois anéis de guia (458), que são móveis axialmente entre si, para expansão da seção central, e distantes entre si para contrair a seção central. Conexões sobrepostas (462, 464) são proporcionadas entre os anéis de guia e um elemento de base (448) suporta os segmentos expansíveis (428).
