Abstract

EN UN CONJUNTO DE PIÑON DE ENGRANAJE Y BARRA DENTADA DE DIRECCION ASISTIDA, DIRIGIDO ESPECIALMENTE PARA VEHICULOS A MOTOR, UN PIÑON (2) SE ENCUENTRA EN LA CAJA (1) DE DIRECCION EN ENGRANAJE CON UNA BARRA (6) DENTADA. UN SERVOMOTOR (11) SE ACOPLA A LA BARRA (6) DENTADA PARA SUMINISTRAR LA ASISTENCIA DE POTENCIA. EL PIÑON (2) ESTA AJUSTADO PARA GIRAR EN UN APOYO (3) FIJO Y UN APOYO (4) SUELTO. EN LA REGION DEL APOYO (4) SUELTO SE DISPONE DE DOS VALVULAS (26,27), SIENDO SUS EJES SUSTANCIALMENTE PERPENDICULARES AL EJE DEL PIÑON (2). EL SOPORTE (4) SUELTO ESTA GUIADO DE TAL FORMA QUE PUEDA MOVERSE PERPENDICULARMENTE CON RESPECTO A SU EJE EN LA CAJA (1) DE DIRECCION SOLAMENTE EN LA DIRECCION DEL EJE DE LAS DOS VALVULAS (26,27) DE CONTROL. EN EL CONJUNTO DE ENGRANAJE DE DIRECCION ASISTIDA DE PIÑON Y BARRA DENTADA, LAS FUERZAS UTILIZADAS PARA ACTUAR LAS VALVULAS DE CONTROL NO SON LAS FUERZAS AXIALES QUE ACTUAN SOBRE EL PIÑON (2), SINO LAS FUERZAS TRANSVERSALES. DE ESTA FORMA LA ACTUACION DE LAS VALVULAS DE CONTROL ES INDEPENDIENTE DEL ANGULO DE HELICE DEL DIENTE DEL PIÑON.
