Abstract:
1. A brake dust collecting device for motor vehicles, the brake dust collecting device comprising: a dust collecting unit; an air flow generating device that generates an air flow that flows across brake parts of a motor vehicle wheel brake and that supplies brake dust of the wheel brake to said dust collecting unit; wherein said air flow generating device comprises at least one rotatable fan blade, wherein said dust collecting unit comprises a filter element, wherein said air flow generating device is arranged within the interior of a wheel rim, said air flow generating device positioned behind an inner side of the wheel rim between axial end faces of the wheel rim and said brake parts, wherein said dust collecting unit is seated on a wheel bearing casing of said motor vehicle and extends radially outwards resting seal-tightly against an axial end face of said wheel rim to form a flow-tight closure between said dust collecting unit and said wheel rim, said flow-tight closure of said dust collecting unit with said wheel bearing casing and said wheel rim end face providing a flow-tight closure of interior space of said wheel rim that forms an unfiltered side of said filter element, wherein said dust collecting unit includes an annular sealing element arranged on a radially outwardly positioned shoulder of said dust collecting unit, said annular sealing element resting seal-tightly against said axial end face of said wheel rim, said annular sealing element effecting said flow-tight closure preventing leak flows between said dust collecting unit and said wheel rim, and wherein said filter element is arranged such that said air flow generated by said air flow generating device flows through and is filtered by said filter element of said dust collecting unit.
