<p>The inventive friction device consists of two friction linings and a support (28) comprising a hub (34) which is radially extended by at least one peripheral blade (36) delimited by two angular edges (38A, 38B) and comprises a bearing surface (44) connected to the first lining and at least one free bearing surface (46A, 46B, 55) contacting with the second lining. The connected (44) and free (46A, 46B) bearing surfaces are separated from each other by the blade slip (50A, 50B) which is delimited by two fold lines (52A, 54A; 52B, 54B). Each angular edge (38A, 38B) comprises a concave part (60A, 60B) delimiting the blade slip (50A, 50B) and the parts of the bearing (44) and free surfaces adjacent to the blade slip (50A, 50B). The concave part (60A, 60B) forms a concave curvature which delimits the blade slip (50A, 50B) at any point and comprises a tangent forming jointly with the fold line nearest to a point where the tangent is regarded an angle ranging from 70 to 110°.</p> |
