Abstract
UNA BIELA DE FUNCIONAMIENTO DE CAMBIO DE PUNTO DE AUTOBLOQUEO SE CONFIGURA PARA ENCAJAR DENTRO DE UN CUBO ANULAR (34). UN MECANISMO DE ANILLO (40) SE ACCIONA CIRCUNFERENCIALMENTE MEDIANTE UN TORNILLO DE BOLA ORIENTADO TANGENCIALMENTE (42) Y CURSOR (44). EL TORNILLO DE BOLA (42) ESTA CONDUCIDO POR UN MOTOR HIDRAULICO (50) CONTROLADO, QUE RESPONDE A UN MOTOR DE CAMBIO DE PUNTO ELECTRICO (74). UN BLOQUEO DE PASO (62) ESTA COLOCADO MEDIANTE LAS ACCIONES COLECTIVAS DEL TORNILLO DE BOLA (42) Y MOTOR DE CAMBIO DE PUNTO (74), CON CUALQUIER MOVIMIENTO RELATIVO A UNA POSICION NULA PRESELECCIONADA, QUE ACCIONA LA VALVULA (60) DE CONTROL BETA (60) DEL MOTOR HIDRAULICO EN POSICION DE FUNCIONAMIENTO.
