A device in a part (1, 24) of a mining or construction vehicle including a wear protection structure (3-9,14, 25, 27), which is intended to comprise a portion of the part that is subjected to wear from abrasive material during loading or dumping. Said wear protection structure has grooves (10-12,15, 26, 28) having an extension that extents at an angle to a general movement direction of abrasive material against the wear protection structure during said loading or dumping. The wear protection structure is positioned such on the part that said abrasive material passes it during loading and/or dumping. The grooves are widening towards an outer surface of the wear protection structure. The invention also concerns a part including such a device.

Ladite structure protégeant contre l'usure possède des rainures (10-12, 15, 26, 28) dotées d'une extension qui se prolonge, en formant un angle avec la direction générale du mouvement du matériau abrasif, contre la structure protégeant de l'usure au cours dudit chargement ou déchargement. La structure protégeant contre l'usure est placée de telle sorte sur la pièce que ledit matériau abrasif la traverse au cours du chargement et/ou déchargement.
