Abstract

BANDA DE RODAGEM DE PNEUMÁTICO DE MULTIESTÁGIOS. Modos de realização particulares da presente invenção incluem uma banda de rodagem de pneumático de multiestágios tendo uma pluralidade de camadas de desgaste, cada uma das mencionadas camadas localizada a uma profundidade diferente da banda de rodagem de pneumático, a banda de rodagem, incluindo um ou mais elementos de banda de rodagem incluindo uma superfície de contato e tendo uma primeira camada de desgaste e uma segunda camada de desgaste, onde a segunda camada de desgaste fica localizada abaixo da primeira camada de desgaste. A banda de rodagem de pneumático também inclui um sulco longitudinal se estendendo em uma direção longitudinal dentro da segunda camada de desgaste do elemento de banda de rodagem, onde o mencionado sulco longitudinal fica exposto após uma profundidade da primeira camada de desgaste ter sido desgastada. A banda de rodagem de pneumático inclui, adicionalmente, um ou mais sulcos laterais se estendendo do sulco longitudinal em uma direção lateral dentro da segunda camada de desgaste do elemento de banda de rodagem. A invenção também provê um elemento de molde para a formação de porções da banda de rodagem de multiestágios.
