Patent number: 11287001Abstract: A ventilated braking band for brake disc having a first plate and a second plate; the first plate has at least a first inner surface, and the second plate has a second inner surface. The first inner surface defines a first inner surface plane or level (z1-z1) coinciding with said first inner surface, and the said second inner surface defines a second inner surface plane or level (z2-z2) coinciding with the second inner surface. The ventilated braking band has connecting elements which extend in an axial direction between the first inner surface and the second inner surface. The ventilated braking band has at least one bulge. The at least one bulge is partially interpenetrated with: at least one portion of the first foot, thus forming a structural continuity with the first foot, thus avoiding the first inner surface level from being reached; or at least one portion of a second foot, thus forming a structural continuity with the second foot, thus avoiding the second inner surface level from being reached.Type: GrantFiled: March 7, 2017Date of Patent: March 29, 2022Assignee: Freni Brembo S.p.A.Inventors: Simone Biondo, Fabrizio Paggi, Stefano Medici, Michele Donati

Patent number: 10738847Abstract: A ventilated braking band for ventilated brake disc, unusually capable of an efficient cooling and structural resistance, has a first plate and a second plate. The ventilated braking band has protrusions which project from a plate without reaching the other plate. Some of the protrusions which project from one of the first or second plate form a protrusion group. The protrusion group forms a continuous or interrupted protrusion group path. The protrusion group projects from both plates, thus forming at least a first and a second protrusion group path. The projections of the first and second protrusion group path cross one another on a plane parallel to the first or second braking surface of the respective plates.Type: GrantFiled: March 3, 2017Date of Patent: August 11, 2020Assignee: Freni Brembo S.p.A.Inventors: Simone Biondo, Stefano Medici, Fabrizio Paggi, Michele Donati
