Abstract

SE DESCRIBE UN SISTEMA DE AMORTIGUADOR NEUMATICO ADAPTADO PARA SU MONTAJE EN UN VEHICULO CON OBJETO DE QUE ABSORBA LOS CHOQUES EJERCIDOS SOBRE EL VEHICULO POR EL PAVIMENTO Y MANTENGA LA CARROCERIA DEL VEHICULO NIVELADA CON RESPECTO A LOS EJES. EL AMORTIGUADOR NEUMATICO (10) COMPRENDE UNA PLACA TERMINAL (12) Y UN PISTON (11) UNIDOS HERMETICAMENTE A LOS EXTREMOS ABIERTOS DE UN MANGUITO DE ELASTOMERO FLEXIBLE (13) PARA FORMAR ENTRE ELLOS UNA CAMARA DE FLUIDO A PRESION. EL MANGUITO DE ELASTOMERO FLEXIBLE SE ENROLLA SOBRE EL PISTON PARA PERMITIR LA EXPANSION Y CONTRACCION DE LA CAMARA DURANTE LOS CHOQUES. ENTRE EL MANGUITO Y EL PISTON ESTA SITUADO UN SENSOR DE ALTURA (40) QUE, EN ALGUNAS REALIZACIONES, COMPRENDE ELEMENTOS MOLDEADOS O EMBEBIDOS EN EL MANGUITO Y/O EL PISTON O EN AMBOS.
