Abstract

SE DESCRIBE UN SISTEMA SENSOR DE FUERZAS PARA EL REGISTRO DE LAS FUERZAS EXISTENTES SOBRE UN PAR DE ELEMENTOS TRACTORES (18, 20) DISTANCIADO UNO DE OTRO DE FORMA TRANSVERSAL, ESPECIALMENTE PARA LA FIJACION DE APARATOS DE REMOLQUES AGRICOLAS. LOS ELEMENTOS TRACTORES (18, 20) AGARRAN EN LA ZONA DE AMBOS EXTREMOS DE UNA BARRA CURVADA (12) QUE DISCURRE TRANSVERSALMENTE. LA BARRA CURVADA (12) SE APOYA EN PIEZAS SOPORTE (14, 16) QUE DISTAN UNA DE OTRA DE FORMA TRANSVERSAL. EN LA ZONA MEDIA DE LA BARRA CURVADA (12), SE ENCUENTRAN COLOCADOS MEDIOS (70) PARA EL REGISTRO DE FLECHA DE FLEXION. PARA LA ELEVACION DE LA SENSIBILIDAD DEL SISTEMA SENSOR DE FUERZAS SE PROPONE, SUJETAR LOS EXTREMOS EN LA BARRA CURVADA (12) DE UNA TIRA (40) QUE SE EXTIENDE TRANSVERSALMENTE. LA TIRA (40) ES ESENCIALMENTE MAS FLEXIBLE QUE LA BARRA CURVADA (12) Y SE CONFORMA SEGUN LA FLEXION DE LA BARRA CURVADA (12). DE ESTA FORMA SE ACERCA EN SU ZONA MEDIA A LA BARRA CURVADA (12). ENTRE LA BARRA CURVADA (12) Y UNA ZONA MEDIA DELA TIRA (40), ESTA COLOCADO UN SENSOR (70) PARA LA MEDIDA DE LAS VARIACIONES DE LA DISTANCIA ENTRE LA VIGA CURVADA (12) Y LA TIRA (40).
