Abstract

La presente invencion se refiere a un blindaje termico mejorado que proporciona tanto aislamiento termico como transmision de ruido reducido para componentes de motores de vehiculos, incluyendo colectores de escape, por ejemplo. La estructura tiene tres capas; una capa metalica, estructural externa, una capa aislante central para aislar el calor y amortiguar el ruido y una capa de metal interna directamente adyacente al componente blindado para reflejar el calor de regreso al componente blindado. Como se ha descrito, el blindaje termico incluye cuando menos una abertura para perno para sujecion del blindaje a un componente blindado, tal como un colector de escape en la realizacion descrita. La abertura esta circunferencialmente bordeada por al menos una ondulacion no plana que define una protuberancia. La protuberancia esta circunferencialmente espaciada alrededor de la abertura. Como la conexion atornillada del blindaje termico al colector es una fuente principal de transmision de vibracion del colector al blindaje, la protuberancia es efectiva para amortiguar la vibracion, y en consecuencia el ruido asociado con la vibracion.
