Abstract

SISTEMA DE DIRECCION HIDRAULICA ASISTIDA PARA VEHICULOS. UN MOTOR DE DIRECCION ASISTIDA PUEDE CONECTARSE OPERATIVAMENTE CON LAS RUEDAS DIRIGIBLES DEL VEHICULO PARA DIRIGIRLAS. UNA VALVULA ACCIONABLE DE DIRECCION ASISTIDA TIENE UNA POSICION NEUTRA EN LA QUE FLUYE FLUIDO POR LA VALVULA DE DIRECCION A UN DEPOSITO DE FLUIDO, Y UNA POSICION ACCIONADA EN LA QUE FLUYE FLUIDO POR LA VALVULA DE DIRECCION AL MOTOR DE DIRECCION. UN CONDUCTO PRINCIPAL CONDUCE FLUIDO DESDE EL ORIFICIO DE SALIDA DE UNA BOMBA A LA VALVULA DE DIRECCION. UN MEDIO DE CONDUCTO DE RETORNO CONDUCE FLUIDO DESDE LA VALVULA DE DIRECCION AL DEPOSITO CUANDO LA VALVULA DE DIRECCION ESTA EN POSICION NEUTRA Y EN POSICION ACCIONADA. UN ORIFICIO ESTA SITUADO EN EL MEDIO DE CONDUCTO DE RETORNO. UNA VALVULA DE DERIVACION DESVIA EL FLUIDO DEL CONDUCTO PRINCIPAL AL DEPOSITO. LA VALVULA DE DERIVACION SE CONTROLA EN RESPUESTA A LA CAIDA DE PRESION POR EL ORIFICIO SITUADO EN EL MEDIO DE CONDUCTO DE RETORNO.
