Abstract

L'invention porte sur une liaison servant à fixer rigidement, à une lèvre d'un godet excavateur d'un équipement d'excavation, un adaptateur destiné à porter de façon amovible une dent d'excavation remplaçable à son extrémité avant. L'adaptateur comporte une branche supérieure et une branche inférieure placées à proximité des surfaces supérieure et inférieure respectives de la lèvre. La liaison présente des ouvertures sensiblement alignées dans les branches et la lèvre, et des sections de prise des branches d'adaptateur traversent l'ouverture de la lèvre à proximité et à l'avant de son extrémité arrière. Une unité d'application de pression, telle qu'un actionneur hydraulique, est agencée à l'intérieur de l'ouverture et génère une force agissant sensiblement horizontalement qui attire l'adaptateur et la lèvre l'un vers l'autre. Un élément de contrainte, qui peut être une pince en C, est accouplé de façon fonctionnelle à l'actionneur hydraulique et se déforme élastiquement par rapport à sa forme détendue lorsqu'il est soumis à la force agissant horizontalement.
