Abstract

LA INVENCION SE REFIERE A UN AMORTIGUADOR DE VIBRACIONES REGULABLE HIDRAULICO PARA VEHICULOS CON UN CILINDRO DE AMORTIGUACION (2), CON UN PISTON DE AMORTIGUACION (1) PROVISTO CON SECCIONES DE ESTRANGULACION (26,27) DEPENDIENTES DE LA PRESION, SUJETO AL VASTAGO DEL PISTON (21), QUE DIVIDE EL CILINDRO AMORTIGUADOR (2) EN UNA PRIMERA Y EN UNA SEGUNDA CAMARA DE TRABAJO (3,4) Y QUE TIENE POR LO MENOS UN PASO BYPASS (5,9,10,6 Y 6,8,7) PARA LA ETAPA DE TRACCION Y DE PRESION DEL AMORTIGUADOR DE VIBRACIONES, EL CUAL ES VARIABLE POR MEDIO DE UNA DISPOSICION DE VALVULA DE CONTROL ELECTROMAGNETICA (34). DE ACUERDO CON LA INVENCION PRESENTA EL PASO BYPASS (5,9,10,6) DE LA ETAPA DE TRACCION Y EL PASO BYPASS (6,8,7) DE LA ETAPA DE PRESION UNA CORREDERA DE VALVULA (13,14) TENSADA POR UN MUELLE (11,12) EN LA POSICION DE CIERRE, LA CUAL LIBERA UNA SECCION DEL PASO BYPASS DEPENDIENTE DE LA DIFERENCIA DE PRESION ENTRE LAS CAMARAS DE TRABAJO (3,4) DEL AMORTIGUADOR DE VIBRACIONES Y LA PRESION AJUSTABLE ELECTROMAGNETICAMENTE DE UNA CAMARA PILOTO (15,16). ADEMAS DE UNA POSIBILIDAD DE AJUSTE SIN ESCALONES DE LA FUERZA DE AMORTIGUACION, PRESENTA EL AMORTIGUADOR DE VIBRACIONES LA VENTAJA DE UNA MEJOR CAPACIDAD DE REACCION CON IMPULSOS DE ALTA FRECUENCIA.
