Abstract

Procedimiento para reducir la dispersión de la fuerza aplicada a la válvula PAS de un vehículo. El procedimiento consiste en adaptar la rigidez de la barra de torsión (3) y/o el acoplamiento (7) entre la barra y el rotor de válvula de dirección ayudada con energía (5) de acuerdo con la diferencia entre la ley medida y la teórica de la válvula. La adaptación puede ser realizada, por ejemplo, seleccionando la posición axial (A, B, C) del perno del conector a fin de modificar la distancia de torsión libre de la barra.
