Brake band for disc of ventilated disc brake

Abstract

A brake band (1) of a ventilated disc brake disc (2) is generally capable of avoiding vibrations that cause annoying whistling during a braking action, said brake band (1) comprising two plates (3, 4) facing each other; the plate (3, 4) comprises an inner surface (5, 6) which directly or indirectly faces the gap (7) and delimits the gap (7); the plate (3, 4) comprises an outer surface (8, 9); said outer surface (8, 9) comprising flat and opposite circumferential portions forming a braking surface (10, 11); the plate (3, 4) comprises a plate body (12, 13) having an extension or a plate thickness (14, 15) in an axial direction (X-X); the plates (3, 4) are connected to one another by means of heat-dissipating elements or connecting elements (16, 17, 18, 19); the connecting elements (16, 17, 18, 19) are shaped as columns and / or ribs which protrude from the plates towards the opposite plates in the form of bridges connecting the plates (3, 4); wherein at least one of the plates (3, 4) comprises at least one shaped pin (20, 21, 22), which is formed from the shape of the plate (3; 4) protrudes into the gap (7) and contacts the opposite plate (4; 3) such that at least one local narrowing of the gap (7) and a thickening of the plate body (12, 13) are formed, thereby producing a local increase in the plate thickness (14, 15); the at least one shaped pin (20, 21, 22) extends at least from a first connecting element (16, 17, 18, 19) to an adjacent connecting element (16, 17, 18, 19) connected to the connecting element (16, 17, 18, 19); and wherein the at least one shaped pin (20, 21, 22) extends at least in the circumferential direction in order to connect at least two adjacent connecting elements (16, 17, 18, 19) lying next to one another in the circumferential direction; and wherein each assembly of shaped pins (20, 21, 22) extends circumferentially along a discontinuous annular path so as to avoid uniform distribution in the circumferential direction.

Description

technical field [0001] The present invention relates to a brake band and a ventilated disc for disc brakes, in particular, but not exclusively, to a brake band and a ventilated disc for disc brakes for applications in the automotive sector, and also to having said ventilated disc disc vehicle. Background technique [0002] Brake calipers in disc brakes are typically arranged across the peripheral outer edge of a brake disc adapted to rotate about an axis of rotation (A-A) defining an axial direction (X-X). Also defined in the disc brake: a radial direction (R-R) substantially orthogonal to said axial direction (X-X); and a positive direction to both said axial direction (X-X) and said radial direction (R-R) Circumferential direction (C-C) intersecting; and also tangential direction (T-T) which is locally orthogonal to both the axial (X-X) and radial (R-R) directions, or more preferably point orthogonal. [0003] As is known, discs for disc brakes comprise a bell adapted to...

Problems solved by technology

[0032] Although satisfactory from many points of view, this known solution does not completely solve the problem and underscores in particular how necessary it is to find a solution with a surface shape that allows the band gap to be bounded
