Abstract

L'invention concerne un disque de friction (1) comprenant un disque support (3) présentant une garniture de friction (6) fixée sur une première et une deuxième face principale (4, 5) du disque support (3). La garniture de friction (6) présente une pluralité de rainures comprenant un premier groupe de rainures internes (10) s’étendant d’un bord intérieur (8) de ladite garniture de friction (6) jusqu’à une zone intermédiaire, et un deuxième groupe de rainures externes (11) s’étendant d’un bord extérieur (7) de ladite garniture de friction (6) jusqu’à ladite zone intermédiaire. Une pluralité de trous traversants (12) sont réalisés au travers du disque support (3) pour relier une rainure interne (10) d’un côté du disque support (3) à une rainure externe (11) sur l’autre face du disque support (3). [Figure accompagnant l’abrégé : Figure 2]The invention relates to a friction disk (1) comprising a support disk (3) having a friction lining (6) fixed on a first and a second main face (4, 5) of the support disk (3). The friction lining (6) has a plurality of grooves comprising a first group of internal grooves (10) extending from an inner edge (8) of said friction lining (6) to an intermediate zone, and a second group of external grooves (11) extending from an outer edge (7) of said friction lining (6) to said intermediate zone. A plurality of through holes (12) are made through the support disc (3) to connect an internal groove (10) on one side of the support disc (3) to an external groove (11) on the other side of the disc support (3). [Figure accompanying the abstract: Figure 2]
