Abstract

Patente de Invenção: <B>"PROCESSO DE AFIXAR EQUIPAMENTO ELETRôNICO SENSìVEL à SUPERFíCIE INTERNA DE UM PNEU"<D>. Uma afixação entre um dispositivo de monitoração e um revestimento interno de um pneu inclui o emprego de um adesivo epóxi que liga o dispositivo de monitoração diretamente com a superfície interna do revestimento interior do pneu. O revestimento interno é primeiramente tornado rugoso de uma maneira que proporciona uma parte áspera do revestimento interno sem remover a inteira espessura do revestimento interno. A inteira espessura do revestimento interno não é removida porque o revestimento interno de preferência tem mais de 1,587 mm de espessura. A espessura do revestimento interno permite que o epóxi curado rígido ligue o dispositivo de monitoração com a superfície interna do revestimento interior enquanto permitindo que o revestimento interno flexione-se com o pneu de modo a não romper a vedação entre o epóxi rígido e o revestimento interno. O dispositivo de monitoração de preferência está preferivelmente localizado em uma área de baixa flexão do pneu para auxiliar a evitar o problema do flexionamento do revestimento interno.
