A wear assembly that includes a wear member and a boss (20) to define an opening for receiving a lock (56) forward of the front edge face of the lip (12) which can mount the wear member in a stable and balanced manner without a through-hole in the lip (12). The wear member includes an aperture and a rib to define bearing faces on opposite sides of a central plane of the lip (12). The boss (20) includes rails to hold the wear member in place, and a brace at the rear end, which supports the rails on the boss (20), abuts the rear of the wear member to reduce the loading on the lip (12), and deflects earthen material away from the wear member under reverse loading.

La présente invention concerne un ensemble d'usure qui comprend un élément d'usure et un bossage définissant une ouverture destinée à recevoir un verrou avant de l'arrête frontale de la lèvre qui peut servir de support à l'élément d'usure d'une manière stable et équilibrée sans alésage percé dans cette lèvre. L'élément d'usure comprend une ouverture et une nervure définissant des faces de palier sur des côtés opposés d'un plan central de la lèvre. Le bossage comprends des rails destinés à tenir l'élément d'usure en place et, une cale au niveau de l'extrémité arrière, qui supporte les rails sur le bossage, vient en butée avec l'arrière de l'élément d'usure afin de réduire la charge portant sur la lèvre et, dévie la terre de l'élément d'usure lors d'un rétrochargement.
