The object of the present invention is a brake band (1) for a ventilated disc brake disc (2), which is capable of significantly avoiding vibrations that cause annoying whistling during a braking operation, and which extends between an inner diameter portion (D1) that is close to a rotational axis (X-X) of the brake band (1) and an outer diameter portion (D2) that is far away from the rotational axis (X-X). The axis of rotation defines an axial direction (X-X); the brake band (1) defines: a radial direction (R-R) substantially orthogonal to the axial direction (X-X); and a circumferential direction (C-C) orthogonal to the axial direction (X-X) and the radial direction (R-R); the brake band (1) comprises 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 one of the plates (3, 4) comprises at least one ridge (20, 21, 22) which extends from one of the plates (3; 4) protrudes into the gap (7) without touching 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); at least one ridge (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 said connecting element (16, 17, 18, 19); and wherein at least one ridge (20, 21, 22) extends at least in the circumferential direction (C-C) in order to connect at least two adjacent connecting elements (16, 17, 18, 19) lying next to one another in the circumferential direction (C-C); and wherein the components of each ridge (20, 21, 22) extend circumferentially along a discontinuous annular path, thereby avoiding uniform distribution in the circumferential direction.

    本发明的对象是通风型盘式制动盘(2)的制动带(1),该制动带(1)能够显著地避免在制动动作期间引起恼人的啸叫声的振动,所述制动带(1)在靠近所述制动带(1)的旋转轴线(X‑X)的内径部(D1)与远离所述旋转轴线(X‑X)的外径部(D2)之间延伸,所述旋转轴线限定轴向方向(X‑X);所述制动带(1)限定有:与所述轴向方向(X‑X)基本正交的径向方向(R‑R);以及与所述轴向方向(X‑X)和所述径向方向(R‑R)正交的周向方向(C‑C);所述制动带(1)包括相互面对的两个板(3、4);所述板(3、4)包括内表面(5、6),所述内表面(5、6)直接或间接地面向间隙(7)并且对所述间隙(7)进行限界;所述板(3、4)包括外表面(8、9);所述外表面(8、9)包括形成制动表面(10、11)的平坦且相反的周向部分;所述板(3、4)包括板本体(12、13),所述板本体(12、13)具有在轴向方向(X‑X)上的延伸部或板厚度(14、15);所述板(3、4)通过散热元件或连接元件(16、17、18、19)相互连结;所述连接元件(16、17、18、19)成形为柱和/或肋,柱和/或肋以将板(3、4)相连接的桥状件的形式从板朝向相对的板突出;其中所述板(3、4)中的一者包括至少一个脊状部(20、21、22),所述脊状部从所述板(3;4)突出到所述间隙(7)中而不触及相对的所述板(4;3),从而形成所述间隙(7)的至少一个局部变窄部以及所述板本体(12、13)的加厚部,由此产生所述板厚度(14、15)的局部增加部;并且至少一个脊状部(20、21、22)至少从第一连接元件(16、17、18、19)延伸到与所述连接元件(16、17、18、19)相连接的相邻连接元件(16、17、18、19);并且其中至少一个脊状部(20、21、22)至少沿着所述周向方向(C‑C)延伸,从而将周向方向(C‑C)上并排放置的至少两个相邻的连接元件(16、17、18、19)相连接;并且其中每个脊状部(20、21、22)的组件沿着不连续的环形路径周向地延伸,从而避免在周向上的均匀分布。
