Abstract

Un aparato sensor de tracción para tractor (10), de tipo dotado de un eje alargado curvable (18) montado sobre puntos de apoyo espaciados (30) en la carcasa de un tractor (32), y miembros de tracción (14) conectados a dicho eje (18) en puntos (34) espaciados respecto a los apoyos, y en los que las fuerzas de los miembros de tracción (14) hacen que el eje (18) ser curve; el citado aparato sensor de tracción responde al curvado de dicho eje, y se caracteriza por: -un conjunto de brazo sensor (50, 52) montado en un extremo del citado eje alargado curvable (18); -medios (60, 82) para asegurar que el otro extremo del conjunto de brazo sensor se moverá por un camino predeterminado en respuesta, sólo a la curvatura del eje (18) originada por cambios en las fuerzas de tracción que han de ser medidas; y -medios (56) para medir el movimiento relativo del citado otro extremo del conjunto de brazo sensor.
