Abstract

DISPOSITIVO PARA REGULAR LA FUERZA DE TRACCION EN LAS BIELAS INFERIORES DEL MECANISMO ELEVADOR DE UN TRACTOR. ESTA CONSTITUIDO POR UNA BARRA DE FLEXION (31) QUE ESTA SOMETIDA A UN MOMENTO DE FLEXION POR UN PAR DE BIELAS INFERIORES (11). LA CURVATURA DE LA BARRA DE FLEXION SE DETERMINA POR UN APARATO DE MEDIDA (34) PROISTO DE UN PALPADOR (38) CON SU ACOPLAMIENTO (22), CUYAS MEDICIONES SON TRANSMITIDAS A UN CIRCUITO DE REGULACION.
