Abstract

SERVODIRECCION HIDRAULICA. LA INVENCION SE REFIERE A UN DISPOSITIVO DE DESCONEXION DE LA PRESION EN LAS POSICIONES FINALES DE AMPLITUD DE LA DIRECCION SERVOASISTIDA. EN LAS DIRECCIONES QUE PRESENTAN UN EMBOLO DE TRABAJO (2) DESPLAZABLE EN EL CARTER DE LA DIRECCION, ESTE DISPOSITIVO DE DESCONEXION SE INCORPORA EN UN TALADRO DE PASO (17) DEL EMBOLO DE TRABAJO (2). PARA CADA SENTIDO DE GIRO ESTA PREVISTA UNA VALVULA DE DESCONEXION (20, 22 O 21, 23) QUE ES ACCIONABLE POR UN EMPUJADOR (24 O 25) QUE AVANZA EN UNA RED (30 Y 31). PARA EVITAR LOS ENTRETENIDOS TRABAJOS DE REGULACION DE LAS VALVULAS DE DESCONEXION (20, 22; 21, 23), LAS PAREDES (30 Y 31) CONTIENEN CASQUILLOS (32 Y 33) ENFRENTADOS A LOS EMPUJADORES (24, 25), QUE UNA VEZ MONTADA LA SERVODIRECCION EN EL VEHICULO SE PUEDEN AJUSTAR AUTOMATICAMENTE A PRESION EN LAS POSICIONES FINALES CORRESPONDIENTES AL ANGULO DE GIRO DE LAS RUEDAS. ESTO OCURRE ASI PORQUE, DESPUES DE PREMONTAR LOS CASQUILLOS (32, 33) EN SUS TALADROS (26 O 27), CON EL EJE DELANTERO LEVANTADO SOBRE TACOS, SE GIRA EN PRIMER LUGAR SIN FUERZA AUXILIAR CONTRA LOS TOPES DE LAS RUEDAS. DE ESTA MANERA SE AJUSTAN A PRESION LOS CASQUILLOS (32 Y 33) POR MEDIO DEL EMBOLO DE TRABAJO (2) EN LA COTA (A) PREVISTA PARA LA DESCONEXION DE LA FUERZA AUXILIAR. AL SER LOS EMPUJADORES (24 Y 25) DE LAS VALVULAS DE DESCONEXION (20, 22; 21, 23) MAYORES EN LA COTA (X) QUE LA PROFUNDIDAD (S) DEL TALADRO DE LOS CASQUILLOS (32 O 33), LA FUERZA AUXILIAR SE DESCONECTA UN POCO ANTES DE LLEGAR A LOS TOPES DE LAS RUEDAS.
