Abstract

FRENO DE TAMBOR PARA ESCALERA MECANICA ACCIONADO MEDIANTE RESORTES Y ACTIVADO ELECTRICAMENTE. SE PRETENDE CONSEGUIR UNA MAYOR FUERZA DE FRENADO CUANDO LA ESCALERA SE MUEVE EN DESCENSO QUE CUANDO ESTA EN ASCENSO Y QUE LAS ZAPATAS DE FRENO SE APLIQUEN SOBRE EL TAMBOR DE ACUERDO CON UN PROGRAMA DE DECELERACION PREFIJADO QUE MINIMICE LAS SACUDIDAS. EL TAMBOR DE FRENO (96) VA MONTADO EN EL ARBOL (72) DEL REDUCTOR MEDIANTE UN CASQUILLO (110). SOBRE LA SUPERFICIE (104) DEL TAMBOR ACTUAN LAS ZAPATAS (116, 118) A TRAVES DE SUS GUARNICIONES 8124, 126). EL SOLENOIDE (194) A TRAVES DE LOS BRAZOS (198) UNIDOS AL YUGO (180) DETERMINA UN MOVIMIENTO DESCENDENTE AL EXCITARSE, QUE LIBERA EL FRENO. LA PRECARGA DEL MUELLE PRIMARIO (174) DETERMINA LA FUERZA MAXIMA DE FRENO APLICADA POR LAS ZAPATAS. UNA DISPOSICION DE MUELLES SECUNDARIOS (184) SE EMPLEA PARA DETERMINAR LA LEY DE FRENADO.
