Abstract

SERVOFRENO DE VACIO DE DOS UNIDADES PARA USO EN VEHICULOS AUTOMOVILES. CADA UNA DE LAS UNIDADES DE SERVO (22) Y (23), ESTAN FORMADAS POR SUS RESPECTIVAS CAMARAS DE TRABAJO (34) Y(44), Y SUS CAMARAS DE VACIO (35) Y (45), CONTROLADAS POR LA VALVULA (10). UN TABIQUE (21) SEPARA AMBAS UNIDADES Y DOS DIAFRAGMAS (31) Y (41) SEPARAN LAS CAMARAS DE TRABAJO (34) Y (44), DE LAS DE VACIO (35) Y (45). AL ACCIONAR EL PEDAL DEL FRENO, EL VASTAGO DE EMPUJE (13) DESPLAZA LA VALVULA (10), CONTROLANDO LA DIFERENCIA DE PRESIONES QUE SE APLICA A CADA UNA DE LAS UNIDADES DE SERVO (22) Y (23). LA FUERZA RESULTANTE DE LA ACCION DEL PEDAL DEL FRENO Y LA OBTENIDA DE LA DIFERENCIA DE PRESIONES, SE TRANSMITE AL CILINDRO MAESTRO (30).
