Abstract

DIRECCION ASISTIDA, EN PARTICULAR PARA VEHICULOS AUTOMOVILES. UNA DIRECCION ASISTIDA, EN PARTICULAR PARA VEHICULOS AUTOMOVILES, PRESENTA UN SERVOCILINDRO (2) DIVIDIDO POR UN SERVOEMBOLO (3) EN DOS ESPACIOS DE TRABAJO (4, 5). UNA VARILLA DE DIRECCION (12) DE UN DISPOSITIVO LIMITADOR HIDRAULICO DE GIRO ESTA GUIADA DE MANERA ESTANCA EN UN TALADRO (11) DEL SERVOEMBOLO (3) Y FIJADA EN DIRECCION AXIAL EN EL SERVOCILINDRO (2). LA VARILLA DE DIRECCION (12) PRESENTA UN TALADRO LONGITUDINAL PASANTE (17) Y DOS ABERTURAS TRANSVERSALES (18, 20). LAS ABERTURAS TRANSVERSALES (18, 20), ESTABLECEN DESDE LAS POSICIONES FINALES DEL SERVOEMBOLO (3) UNA CONEXION ENTRE EL CORRESPONDIENTE ESPACIO DE TRABAJO (4, 5) IMPULSADO CON ALTA PRESION Y EL TALADRO LONGITUDINAL (17). EN CADA EXTREMO (13, 14) DE LA VARILLA DE CONEXION (12) ESTA PREVISTA UNA VALVULA DE RETENCION (23, 24) QUE PERMITE UN PASO DE ACEITE DESDE EL INTERIOR DEL TALADRO LONGITUDINAL (17) DENTRO DEL ESPACIO DE TRABAJO ADYACENTE (4, 5) Y QUE INTERRUMPESIN EMBARGO EL PASO DEL ACEITE DESDE EL ESPACIO DE TRABAJO ADYACENTE (4, 5) A TRAVES DEL TALADRO LONGITUDINAL (17).
