Title (EN) VENTILATED BRAKING BAND, VENTILATED BRAKE DISC AND METHOD OF VENTILATION
(FR) BANDE DE FREINAGE VENTILÉE, DISQUE DE FREIN VENTILÉ ET PROCÉDÉ DE VENTILATION
Abstract:
(EN) A ventilated braking band (100) for ventilated brake disc (1) comprises a first plate (2) and a second plate (3), said first plate (2) and said second plate (3) are mutually spaced apart in axial direction so as to delimit a gap therebetween, said first plate (2) comprises at least a first inner surface (7) facing said second plate (3), and in which said first inner surface is substantially parallel to said first braking surface (5), said second plate (3) comprises a second inner surface (8) facing said first plate (2), and in which said second inner surface is substantially parallel to said second braking surface (6), said ventilated braking band (100) comprises connecting elements (9) which extend in an axial direction between said first inner surface and said second inner surface (7, 8), connecting together said first plate (2) and said second plate (3), said ventilated braking band (100) comprises protrusions (10) which project from a plate (2, 3) in said gap without reaching the faced plate (3, 2), each of said protrusions (10) connects together at least two separate connecting elements (9), some of said protrusions (10) which project from one of said first or second plate (2, 3) form a protrusion group (103); said protrusion group (103) forms a continuous or interrupted protrusion group path (106), which develops from the proximity of the radially inner edge (104) to the proximity of the radially outer edge (105) of the plate (2, 3), said protrusion group (103) projects from both plates (2, 3), thus forming at least a first and a second protrusion group path (106, 107), the projections of said first and second protrusion group path (106, 107) cross one another on a plane parallel to the first or second braking surface (5, 6).
(FR) L'invention concerne une bande de freinage ventilée (100) pour disque de frein ventilé (1), laquelle bande comprend une première plaque (2) et une seconde plaque (3), ladite première plaque (2) et ladite seconde plaque (3) étant mutuellement espacées dans une direction axiale de façon à délimiter un espace entre elles, ladite première plaque (2) comprenant au moins une première surface interne (7) faisant face à ladite seconde plaque (3), et ladite première surface interne étant sensiblement parallèle à ladite première surface de freinage (5), ladite seconde plaque (3) comprenant une seconde surface interne (8) faisant face à ladite première plaque (2), et ladite seconde surface interne étant sensiblement parallèle à ladite seconde surface de freinage (5), ladite seconde plaque (3) comprenant une seconde surface interne (8) faisant face à ladite première plaque (2), et ladite seconde surface interne étant sensiblement parallèle à ladite seconde surface de freinage (6), laquelle bande de freinage ventilée (100) comprend des éléments de liaison (9) qui s'étendent dans une direction axiale entre ladite première surface interne et ladite seconde surface interne (7, 8), reliant ensemble ladite première plaque (2) et ladite seconde plaque (3), et laquelle bande de freinage ventilée (100) comprend des saillies (10) qui font saillie à partir d'une plaque (2, 3) dans ledit espace sans atteindre la plaque en vis-à-vis (3, 2), chacune desdites saillies (10) reliant ensemble au moins deux éléments de liaison séparés (9), certaines desdites saillies (10) qui font saillie à partir de l'une desdites première ou seconde plaques (2, 3) formant un groupe de saillies (103) ; ledit groupe de saillies (103) formant une trajectoire de groupe de saillies continue ou interrompue (106), qui se développe à partir du voisinage du bord radialement interne (104) jusqu'au voisinage du bord radialement externe (105) de la plaque (2, 3), ledit groupe de saillies (103) faisant saillie à partir des deux plaques (2, 3), de façon à former ainsi au moins une première et une seconde trajectoire de groupe de saillies (106, 107), les saillies desdites première et seconde trajectoires de groupe de saillies (106, 107) se croisant mutuellement sur un plan parallèle à la première ou à la seconde surface de freinage (5, 6).
