  • Patent number: 8869953
    Abstract: A brake disc is provided having ribs arranged between two friction rings, extending radially with side walls standing essentially perpendicular to the friction rings to bound air cooling ducts. At least one of the side walls of one, two, three, or five ribs is inclined with respect to the perpendicular ribs to avoid squealing noise. At least one of the ribs having at least one inclined side wall has a thickness measured in the direction perpendicular to the side wall which differs from the thickness of the perpendicular ribs. When two, three, or five ribs having inclined walls are present, the angles enclosed between these ribs preferably are not all the same. Any imbalance resulting from this non-uniform distribution of ribs having an inclined side wall is essentially eliminated by adding material on selected perpendicular ribs.

  • Publication number: 20100282552
    Abstract: A brake disc is provided having ribs which are arranged between two friction rings, extend essentially in the radial direction and bound air cooling ducts by their side walls standing essentially perpendicular to the surface of the friction rings. At least one of the side walls of one, two, three, or five ribs is inclined with respect to the perpendicularly standing ribs in order to avoid disturbing squealing noise. In the case of at least one of the ribs having at least one inclined side wall, the rib thickness measured in the direction perpendicular with respect to the side wall differs from the thickness of the perpendicularly standing ribs. In the case of two, three, or five ribs, of which at least one side wall is inclined with respect to the perpendicularly standing ribs, the angles enclosed between these ribs having the inclined side wall preferably are not all the same.
