Abstract

SISTEMA HIDRAULICO PARA UNA SERVODIRECCION DE VEHICULO AUTOMOVIL. EN UN SISTEMA QUE INCORPORA: -UNA VALVULA PRINCIPAL QUE PRODUCE LA PRESION DE ASISTENCIA (PSIA) Y DOS CIRCUITOS PARALELOS ENTRE UNA FUENTE (14) DE FLUIDO A PRESION Y UN DEPOSITO (16), CADA UNO DE CUYOS CIRCUITOS TIENE AL MENOS DOS ESTRANGULADORES (1, 2, 1'', 2'') MODULABLES Y ESTANDO EL PUNTO DE CONFLUENCIA DE LOS ESTRANGULADORES CONECTADOS A UNA CAMARA RESPECTIVA DEL DISPOSITIVO HIDRAULICO DE ASISTENCIA (12); -Y UNA VALVULA SECUNDARIA QUE PRODUCE LA PRESION DE REACCION (PSIR) APLICADA AL ARBOL DEL VOLANTE DE DIRECCION Y QUE INCLUYE UN SEGUNDO PAR DE CIRCUITOS DE FLUIDO PARALELOS ENTRE UNA FUENTE (24) DE FLUIDO A PRESION Y UN DEPOSITO (16), CADA UNO DE CUYOS CIRCUITOS TIENE AL MENOS DOS ESTRANGULADORES (3, 4, 3, 4'') MODULABLES; -LA FUENTE (14) SUMINISTRA UN CAUDAL DE FLUIDO FIJO, Y LA FUENTE (24) SUMINISTRA UN CAUDAL DE FLUIDO VARIABLE POR UNA BOMBA ACCIONADA EN FUNCION DE LA VELOCIDAD DEL VEHICULO. SE CONTROLA LA REACCION DE LA DIRECCION EN FUNCION DE LA VELOCIDAD DEL VEHICULO CON UN COSTE REDUCIDO.
