Abstract

DENTRO DE LA CARCASA (1) DE UN NEUMATICO (2), EN CADA PARED LATERAL (5) DE LA MISMA, HAY UNA PRIMERA Y UNA SEGUNDA PIEZA INTERCALADAS DE REFUERZO ELASTOMERICAS (13, 15) INTERPUESTAS ENTRE UNA PRIMERA Y UNA SEGUNDA CAPA DE LA CARCASA (10, 11) Y CADA UNA DE ELLAS VA SIENDO CADA VEZ MAS DELGADA CONFORME VA HACIA LOS EXTREMOS OPUESTOS RESPECTIVOS DE SU PROPIA SECCION. LAS PIEZAS INTERCALADAS DE REFUERZO (13, 15) ESTAN UNIDAS ENTRE SI ALINEADAS RESPECTO AL PUENTO DEL CORDON MAXIMO (14) DEL NEUMATICO (2). UNA TERCERA PIEZA ELASTOMERICA (16) DE SECCION TESTICULAR, CUBRE INTERNAMENTE LA PRIMERA CAPA (10) Y PRESENTA UN AREA DE GROSOR MAXIMO (16A) ALINEADA RESPECTO AL AREA DE UNION (14) ENTRE LAS PIEZAS INTERCALADAS DE REFUERZO (13, 15). LAS PIEZAS INTERCALADAS DE REFUERZO (13, 15) SE COMPORTAN COMO BRAZOS RIGIDOS, ARTICULADOS MUTUAMENTE EN EL PUNTO DE UNION (14) DE LOS MISMOS, SIENDO EL MOVIMIENTO CERCANO A CADA UNO DE DICHOS BRAZOS CONTRARRESTANDO POR UNA TERCERA PIEZA INTERCALADA ELASTOMERICA (16)QUE SE COMPORTA COMO UN RESORTE.
