Abstract

EL APARATO Y EL METODO UTILIZAN UN PAR DE TRANSDUCTORES, TALES COMO LASERES, MONTADOS SOBRE EL CONJUNTO LLANTA / RUEDA DE UN VEHICULO PARA MEDIR LOS ANGULOS REALES DE CONVEXIDAD EXPERIMENTADA POR EL VEHICULO, COMO CUANDO EL VEHICULO SE MUEVE A LO LARGO DE LA SUPERFICIE DE UNA CARRETERA REAL. EL PAR DE LASERES SE MONTAN EN UNA RELACION PREDETERMINADA HORIZONTAL, ESPACIADA SOBRE UNA ABRAZADERA INSTALADA Y EXTENDIENDO PERPENDICULARMENTE POR FUERA DESDE UN EJE NO GIRATORIO MONTADOS SOBRE EL CONJUNTO LLANTA / RUEDA. EL HAZ DE LASER REFLEJADO DESDE EL PAR DE LASERES, SON CONTINUAMENTE MEDIDOS CUANDO EL VEHICULO CUANDO SE MUEVE A LO LARGO DE LA SUPERFICIE DEL CAMINO. LOS HACES REFLEJADOS DETERMINAN EL CAMBIO EN ESPACIAMIENTOS DE LOS DOS DE LASERES POR ENCIMA DE LA SUPERFICIE DEL CAMINO, DESDE LA CUAL PUEDEN SER CALCULAR LOS ANGULOS DE CONVEXIDAD CONTINUAMENTE IMPARTIDOS SOBRE EL CONJUNTO LLANTA / RUEDA. ESTOS DATOS SON RECOGIDOS Y ALMACENADO EN UNA COMPUTADORA UBICADA EN EL VEHICULO, Y CAPTURA LOSANGULOS DE CONVEXIDAD DE LAS LLANTAS EN FUNCIONAMIENTO CON EL RESPECTO A LA SUPERFICIE DEL CAMINO REAL, CUANDO SE USAN SOBRE UN VEHICULO EN PARTICULAR. LOS DATOS ALMACENADOS SE APLICAN LUEGO AL EQUIPO DE COMPROBACION DE LLANTAS PARA UNA POSIBILIDAD DE PRUEBA REMOTA, Y PARA REPETIR LA EXPERIENCIA DE CONVEXIDAD DEL CAMINO REAL SOBRE LA LLANTA DE PRUEBA, Y PARA OTRAS LLANTAS DE PRUEBA CON LA POSIBILIDAD DE HACER UNA PRUEBA SIMULANDO LAS CONDICIONES MEDIOAMBIENTALES DEL MUNDO REAL, Y PARA UNA LLANTA EN PARTICULAR O SOBRE UN VEHICULO EN PARTICULAR, SIN NECESIDAD DE REPETIR MAS PRUEBAS COSTOSAS SOBRE EL MOVIMIENTO REAL DEL VEHICULO EN UNA PISTA REMOTA DE PRUEBA.
