Abstract

UN AMORTIGUADOR PARA VEHICULOS DE FERROCARRIL, COMPRENDIENDO DOS FUELLES "DE CAUCHO" (7) CONECTADOS A UNA TOBERA O BOQUILLA (1). LA TOBERA ESTA FORMADA POR UN ORIFICIO AHUSADO, EN FORMA DE DOS PERFORACIONES CONICAS, VERTICE A VERTICE, QUE SE SEPARAN DESDE UNA SECCION TRANSVERSAL COMUN (3), ESTANDO ESTA UNIDAD COMPLETAMENTE LLENA DE UN FLUIDO AMORTIGUADOR (9), QUE ESTA FORMADO POR PARTICULAS DE HIERRO BLANDO (HIERRO FACILMENTE IMANADO POR INDUCCION, PERO QUE PIERDE EL MAGNETISMO CUANDO NO ACTUA EL CAMPO MAGNETICO), SUSPENDIDAS EN ACEITE O FLUIDO HIDRAULICO. ESTA UNIDAD COMPLETA SE EXTIENDE ENTRE DOS CONTENEDORES DE FLUIDO (8, 10), QUE SE COMPRIMEN DIFERENCIALMENTE DESDE UN CILINDRO DIRECTOR (19) DE DOBLE ACCION. TAL PRESION DIFERENCIAL HACE QUE UN FUELLE (7) SE COMPRIMA Y EL OTRO SE EXPANDA, BOMBEANDO ASI EL FLUIDO DE AMORTIGUAMIENTO A TRAVES DE LA TOBERA (1), Y EJERCIENDO UNA FUERZA DE AMORTIGUAMIENTO.
