Abstract

Cette invention concerne un dispositif de direction destiné à une remorque ou similaire où une bielle de direction (6) est placée entre une remorque à direction avant ou similaire (1) comprenant un véhicule automoteur doté d’un moyen de direction installé à proximité de roues avant directrices et un tracteur (4) qui tracte la remorque ou similaire par un organe de liaison central. Une variation de la distance entre le tracteur et la remorque résultant de la conduite du tracteur est transmise à un moyen de direction par la bielle afin que la direction de la remorque soit commandée en relation avec celle du tracteur. Un mécanisme de raccord d’armature (80) est disposé dans le moyen de direction relié à la bielle. Même si la section de liaison est poussée ou tirée obliquement et tournée, cette section assurant la liaison du moyen de direction est renforcée par le mécanisme de raccord d’armature.
