Title
(EN) BLOCKS FOR WHEEL BRAKES
(FR) PATINS POUR FREINS DE ROUE
Abstract
(EN) A block (1) for wheel brakes comprising (i) a friction portion (2), in which a friction surface (5) is defined, which, in use, acts upon a peripheral surface of a wheel in order to carry out the braking action, (ii) a support plate (3), which is fixed, in an irreversible manner, to a surface (6) of the friction portion (2) opposite the friction surface (5), and (iii) a base plate (4), which is fixed to the support plate (3) and comprises a coupling element (4a) to fix the block (1) as a whole to a brake system. The block (1) comprises at least one elastic element (12) placed between the support plate (3) and the base plate (4). The presence of the elastic element (12) creates a ventilation air space (I) between the support plate (3) and the base plate (4).
(FR) La présente invention concerne un patin (1) pour des freins de roue comprenant (i) une partie de frottement (2), dans laquelle une surface de frottement (5) est définie, laquelle, en utilisation, agit sur une surface périphérique d'une roue de façon à effectuer l'action de freinage, (ii) une plaque de support (3), qui est fixée, de manière irréversible, à une surface (6) de la partie de frottement (2) opposée à la surface de frottement (5), et (iii) une plaque de base (4), qui est fixée à la plaque de support (3) et comprend un élément de couplage (4a) pour fixer le patin (1) dans son ensemble à un système de freinage. Le patin (1) comprend au moins un élément élastique (12) placé entre la plaque de support (3) et la plaque de base (4). La présence de l'élément élastique (12) crée un espace d'air de ventilation (I) entre la plaque de support (3) et la plaque de base (4).
