Abstract

LA INVENCION SE REFIERE A UN APARATO DE CONTROL DE ROTACION LIBRE EN UN CONJUNTO ELEVADOR EN EL QUE SE PREVE, ENTRE UN MANECILLA OPERATIVA 18 Y UN TOPE 17 PREVISTOS EN EL ARBOL DE MANDO 5, UN MUELLE DE ROTACION LIBRE 19 PARA FORZAR LA MANECILLA 18 HACIA EL ELEMENTO MOTOR 8 Y FORZAR EL ELEMENTO MOTOR 8 EN LA DIRECCION DE LIBERACION DEL FRENO. CUANDO LA MANECILLA DE FUNCIONAMIENTO 18 ES EMPUJADA, EL ELEMENTO MOTOR 8 ES GIRADO POR UNA FUERZA DE TORSION DEL MUELLE 19 DE MANERA A SEPARARLO DE UN ELEMENTO ACCIONADO. TRAS ESTO UNA ACCION DEL FRENO CAUSADO POR UNA RUEDA DE TRINQUETE DE FRENO 11 Y UNOS DISCOS DE FRENO 9, 10 ES CANCELADA Y UNAS ESPIGAS DE INTRODUCCION 31 SON PUESTA EN CONTACTO RESILIENTE CON SUPERFICIES DE CONTROL DE LIBRE ROTACION 35 POR UN FUERZA AXIAL DEL MUELLE 19, DE MANERA QUE EL CONTROL DE LIBRE ROTACION PUEDA MANTENERSE.
