Abstract

VALVULA DE FRENADO ANTIDESLIZANTE PARA VEHICULOS. LA VALVULA (12) CONTROLA LA PRESION A LA ENTRADA Y SALIDA DE LA BOMBA DE FRENADO Y DEL BOMBIN DE FRENOS (6)-(7) DE CADA RUEDA (2)-(3); A SU VEZ LA VALVULA ESTA CONECTADA A UNOS SENSORES (29) Y (30) LIMITADORES DE LA PRESION. DICHOS SENSORES (29) (30) ESTAN FORMADOS POR UN SOLENOIDE. EL DESLIZAMIENTO DE LA RUEDA ES DETECTADO POR UN CIRCUITO ELECTRICO QUE ENVIA LAS SEÑALES AL SOLENOIDE PARA REGULAR LA PRESION DE FRENADO. AL PISAR EL PEDAL DE FRENO (18) SE PRODUCE UNA PRESION EN EL CILINDRO MAESTRO (15), PERO CUANDO ESTE ALCANZA UNOS VALORES SUPERIORES A LOS NORMALES DANDO LUGAR AL DESLIZAMIENTO DE LAS RUEDAS, ESTO ES DETECTADO POR EL ACELEROMETRO (28) Y LOS SENSORES (29) Y (30) ABRIENDOSE LA VALVULA (12) DERIVANDO EL CIRCUITO PARA IMPEDIR EL BLOCAJE DE LAS RUEDAS (2)-(3). EL CILINDRO MAESTRO (15), LOS CONDUCTOS (8)-(9)-(10)-(13) Y LOS BOMBINES (6) Y (7) FORMAN UN CIRCUITO INDEPENDIENTE DE LA VALVULA DE CONTROL (12) FORMANDO UN CIRCUITO EN PARALELO EN EL CASO DE QUE SE PRODUZCAN AVERIAS EN EL SISTEMA DE FRENADO.
