Abstract

"NERVURAS DE SUPORTE DE REFORçO DE BANDA DE RODAGEM PARA PNEUMáTICO DE FUNCIONAMENTO VAZIO". Um pneumático (10) incorpora uma pluralidade de elementos de suporte de reforço de banda de rodagem, alinhados em paralelo (23) dispostos tipicamente lateralmente entre a banda de rodagem (12) e a estrutura de lona (16). Os elementos de suporte (23) inibem a elevação lateral e circunferencial da banda de rodagem durante a operação de funcionamento vazio. Os elementos de suporte (23) podem ser uma nervura monolítica (22) feita de um material plástico reforçado com fibra. Uma nervura em camadas alternativa (24) possui duas camadas externas (40, 44) de um material plástico reforçado com fibra enquanto a camada central (42) é um elastómero."TIRES REINFORCEMENT SUPPORT NERVES FOR EMPTY OPERATING PNEUMATICS". A tire (10) incorporates a plurality of tread reinforcement support elements, aligned in parallel (23), typically arranged laterally between the tread (12) and the canvas structure (16). The support elements (23) inhibit the lateral and circumferential elevation of the tread during empty operation. The support elements (23) can be a monolithic rib (22) made of a fiber-reinforced plastic material. An alternative layered rib (24) has two outer layers (40, 44) of a fiber-reinforced plastic material while the central layer (42) is an elastomer.
