Publication number: 20240133436Abstract: A braking band extending between an inner diameter and an outer diameter has two plates facing each other and having inner surfaces delimiting a gap. The two plates are joined by connecting elements projecting from one of the two plates and reaching the opposite plate. A first series of fins of the connecting elements is each a fin which is in a single piece and extends from near the inner diameter to near the outer diameter and has a fin outer end portion having a predetermined extension along an outer circumferential width, and a fin inner end portion having a predetermined extension along an inner circumferential width. Considering a section taken along a section plane including the radial and circumferential directions, the outer circumferential width is greater than the inner circumferential width and the fin outer end portion of each fin faces only an adjacent fin on both sides in circumferential direction.Type: ApplicationFiled: October 13, 2020Publication date: April 25, 2024Applicant: BREMBO S.p.A.Inventors: Lorenzo CAVAGNA, Nino RONCHI

Patent number: 11846334Abstract: A braking band has a first plate and an opposite second plate having inner surfaces delimiting a gap, outer surfaces forming braking surfaces, and a plate body. The plates are joined by connecting elements. At least one plate has at least one ridge projecting into the gap without reaching the opposite plate. The ridge extends from a first connecting element to an adjacent connecting element, and along a circumferential direction, the connecting elements and the ridge being groupable in modules circumferentially distributed along the gap. A first module has three adjacent connecting elements connected by two ridges projecting from the first plate into the gap without reaching the second plate. A second module has three adjacent connecting elements connected by two ridges projecting from the second plate into the gap without reaching the first plate. A third module has at least one connecting element free of ridge connection.Type: GrantFiled: December 5, 2019Date of Patent: December 19, 2023Assignee: Brembo S.p.A.Inventors: Lorenzo Cavagna, Nino Ronchi

Patent number: 11542996Abstract: Some pin elements may have a substantially circular cross section, forming a circumference-shaped edge. Other pin elements may have a substantially rhomboidal cross section, forming a symmetric rhombus-shaped edge with respect to a radial direction and a circumferential direction orthogonal to this radial direction. Yet other pin elements may have a substantially circular cross section, forming a circumference-shaped edge.Type: GrantFiled: December 18, 2017Date of Patent: January 3, 2023Assignee: Freni Brembo S.p.A.Inventors: Nino Ronchi, Antonio Quarti, Lorenzo Cavagna, Fabiano Carminati

Publication number: 20190353216Abstract: A method for controlling the braking action applicable by a brake caliper on a mechanical movement member of a vehicle is described. An electronic control unit operatively connected to an actuator assembly receives an input signal representative of a braking request. The unit determines a first reference value of a position of a component in the actuator assembly and a second reference value of a parameter representative of the braking action applicable by a brake caliper via the actuator assembly. The unit determines at least one feedback value of the position of a component in the actuator assembly. The unit also generates at least one control signal for the actuator assembly based on feedback values and the reference values.Type: ApplicationFiled: December 18, 2017Publication date: November 21, 2019Inventors: NINO RONCHI, ANTONIO QUARTI, LORENZO CAVAGNA, FABIANO CARMINATI

Patent number: 9022182Abstract: Brake band (14) of a disc for a ventilated disc brake, unusually capable of reducing braking whistling, extends between an inner diameter (D1), close to a rotation axis (X-X) of the brake band (14), and an outer diameter (D2), far from said rotation axis (X-X) of the disc, said brake band (14) comprising two plates (16, 18) facing one another and defining a gap (22), comprising two plates (16, 18) being joined together by heat dissipation and connection means or elements (20, 60), said connection means (20, 60) being shaped like small columns that project from one plate towards the opposite plate in the form of pins (20, 60) remaining inside said gap (22), said pins (20, 60) being grouped in at least two rows or tiers (26, 28, 30) arranged circumferentially. Some of the pins (60) arranged in said second tier (28 or 30) having a section shaped like a rhombus or diamond with four vertices joined by four sides in which said sides defining said section are substantially rectilinear in shape.Type: GrantFiled: November 12, 2010Date of Patent: May 5, 2015Assignee: Freni Brembo S.p.A.Inventors: Lorenzo Cavagna, Nino Ronchi

Patent number: 7690484Abstract: A braking band with a remarkable capacity for improved cooling, for use in disk-brake disks, comprises two plates coaxial with an axis, facing one another, and spaced apart to form a space in which an air-flow takes place from the axis towards the outer side of the band, the plates having facing surfaces from which pillar-like elements extend, transversely, to connect the plates, the pillar-like elements being distributed in circular rings or rows concentric with the plates so as to be distributed uniformly in the space, those pillar-like elements which are disposed in inside rows of the braking band having rhombic cross-sections. The rhombic cross-sections of the pillar-like elements which are in inside rows of the band are symmetrical with respect to an axis transverse the direction of flow and each element for connection between the plates extends from one plate to the other whilst remaining within the space.Type: GrantFiled: April 5, 2002Date of Patent: April 6, 2010Assignee: Freni Brembo S.p.A.Inventors: Leone Oberti, Lorenzo Cavagna, Giuseppe Meroni

Publication number: 20040182660Abstract: The disk is formed by an annular braking band, by a bell, and by connecting means between the band and the bell. The bell has a plurality of radial recesses around its periphery. The connecting devices comprise a corresponding plurality of drive elements, each fitted in a radial recess of the bell with the ability to move substantially only radially, and a corresponding plurality of flat springs arranged to permit resilient axial play between the band and the bell.Type: ApplicationFiled: December 12, 2003Publication date: September 23, 2004Inventors: Lorenzo Cavagna, Leone Oberti
