Abstract

La présente invention concerne une entretoise de friction adaptée à être intercalée entre deux organes mécaniques pour pouvoir transmettre un effort entre lesdits deux organes mécaniques, ladite entretoise de friction comprenant une pièce plate (20) présentant deux surfaces opposées (18) définissant une épaisseur, et une pluralité d’aspérités (16) s’étendant en saillie d’au moins une desdites surfaces (18), les aspérités (16) de ladite pluralité d’aspérités s’étendant de ladite au moins une desdites surfaces (18) opposées d’une hauteur moyenne déterminée. Ladite pièce plate (20) et lesdites aspérités (16) sont faites d’un même matériau métallique, et ledit même matériau métallique s’étend continument entre ladite pièce plate (20) et lesdites aspérités (16). Figure à publier avec l’abrégé : Fig. 3
