Abstract

UN SISTEMA DE DIRECCION ASISTIDA INCLUYE UN PRIMER Y UN SEGUNDO MIEMBRO DE VALVULA (40 Y 42) QUE SON RELATIVAMENTE MOVILES ENTRE SI PARA LLEVAR FLUIDO A UN MOTOR DE DIRECCION ASISTIDA DE UN VEHICULO (31) Y UNA BOMBA (24) PARA SUMINISTRAR FLUIDO AL PRIMER Y UN SEGUNDO MIEMBRO DE VALVULA (40 Y 42) Y AL MOTOR DE LA DIRECCION ASISTIDA. UN MIEMBRO DE TRANSMISION DE FUERZA (116) ESTA CONECTADO CON EL PRIMER MIEMBRO DE VALVULA (40) Y PUEDE MOVERSE HACIA Y DESDE EL SEGUNDO MIEMBRO DE VALVULA (42) PARA APLICAR UNA FUERZA PARA CONTENER EL MOVIMIENTO RELATIVO ENTRE EL PRIMER Y EL SEGUNDO MIEMBRO DE VALVULA. UNA CAMARA DE PRESION DE FLUIDO (138) RECIBE FLUIDO DESDE LA BOMBA (24), LA PRESION DEL FLUIDO ACTUA SOBRE EL MIEMBRO DE TRANSMISION DE FUERZA (116). EL PRIMER Y EL SEGUNDO MIEMBRO DE VALVULA INCLUYEN CONDUCTOS PARA CONDUCIR EL FLUIDO HASTA LA CAMARA DE PRESION DE FLUIDO (138). UN ORIFICIO DE SANGRADO DE TAMAÑO FIJO (182) CONDUCE FLUIDO DESDE LA CAMARA DE PRESION HASTA UN DEPOSITO (32). EL ORIFICIO(132) RESTRINGE EL FLUJO DEL FLUIDO DESDE LA CAMARA HASTA EL DEPOSITO. UN MOTOR DE VELOCIDAD VARIABLE (14) QUE IMPULSA LA BOMBA (24) VARIA LA VELOCIDAD DEL FLUJO DEL FLUIDO HACIA LA CAMARA (138) COMO FUNCION A LA VELOCIDAD DEL VEHICULO PARA VARIAR LA PRESION EN LA CAMARA.
