Claim Text:
1. An assembly comprising: a connection flange and a brake disc; wherein said connection flange comprises an annular body extending around an axis of symmetry, said annular body comprising an inner ring suitable for connecting to said brake disc and having a first surface extending substantially radially and facing said brake disc and a second surface opposite said brake disc, said inner ring further having a disc coupling portion, said body further comprising an outer ring suitable for connecting to a wheel rim and having a third surface extending substantially radially and facing said brake disc and a fourth surface opposite said brake disc and facing the wheel rim, said outer ring further having a rim coupling portion, said annular body further comprising an intermediate joining portion positioned between said inner ring and said outer ring, said intermediate portion having a plurality of through openings distributed circumferentially, said through openings each having an opening edge that includes a radially inner portion that defines said opening towards said axis of symmetry; wherein said brake disc is arranged around a rotation axis and comprises a brake band that extends around said rotation axis, said brake band forming two opposite braking surfaces suitable for cooperating with pads of a brake caliper arranged astride of said brake band, said brake disc defining an axial direction coinciding with or parallel to said rotation axis, a radial direction that defines a radially outer direction when going away from said axial direction, a radially inner direction when going towards said axial direction, and a circumferential direction perpendicular to said axial direction and said radial direction, said brake disc also comprising a drum including a drum connection flange that has a connection portion suitable for connecting said drum to a wheel bearing, said connection portion comprising a surface facing the wheel bearing and an opposite surface facing said connection flange, said brake disc being arranged with its connection flange positioned between the wheel bearing and said connection flange, said drum also comprising an edge portion that is arranged radially outside of said connection portion and that is suitable for connecting said drum to the wheel bearing, said drum also comprising a drum body that connects said edge portion to said brake band, said drum body defining an outer space comprised between said drum and the wheel rim, said drum body being suitable for creating a gap between said drum and the wheel bearing housed in said drum, said gap running axially according to said axial direction substantially along the entire drum until it reaches said edge portion, wherein said edge portion defines at least one drum opening that places said gap present between said drum body and the wheel bearing in communication with a space outside of said drum, said drum opening having an opening edge that includes a radially inner portion; and wherein said radially inner portion of said opening edge of at least one of said through openings of said connection flange is substantially radially aligned with said radially inner portion of said opening edge of said at least one drum opening.
