Title (EN) BRAKE PAD ASSEMBLY
(FR) ENSEMBLE DE PLAQUETTES DE FREIN
Abstract:
(EN) This brake pad assembly (1) for disk brakes, in particular in rail vehicles, comprises a main plate (2), pad modules (3) attached to the plate, which have a friction lining (9) and a backing plate (10), means (16) for attaching a respective pad module (3) to the plate (2), a plurality of bushes (7), each attachment means being arranged in a respective bush (7), which is inserted into orifices (11,6) provided facing each other in the backing plate (10) and in the main plate (2), through an opening (8) in the friction lining (9). According to the invention, the orifice for receiving the bush in the main plate is a blind hole (6), a bore (15) with a smaller diameter than that of the blind hole (6) being provided in the bottom of said blind hole, said bore (15) passing through the main plate (2), a rivet (16) being inserted into said bore inside the bush (7), said rivet linking the main plate (2) and the backing plate (10). The present invention therefore makes it possible to produce a brake pad assembly in which the link between the pad module and the main plate has a structure that is as simple as possible, while being reliable.
(FR) Cet ensemble de plaquettes de frein (1) pour freins à disques, en particulier dans des véhicules ferroviaires, comprend une platine principale (2), des modules de plaquette (3) fixés sur la platine, qui présentent une garniture de friction (9) et une plaque d'appui (10), des moyens (16) de fixation d'un module de plaquette respectif (3) sur la platine (2), une pluralité de douilles (7), chaque moyen de fixation étant disposé dans une douille (7) respective, laquelle est insérée dans des orifices (11,6) ménagés mutuellement en regard dans la plaque d'appui (10) et dans la platine principale (2), au travers d'une ouverture (8) de la garniture de friction (9). Selon l'invention, l'orifice pour la réception de la douille dans la platine principale est un trou borgne (6), un alésage (15) de diamètre plus petit que celui du trou borgne (6) étant prévu dans le fond de ce trou borgne, cet alésage (15) traversant la platine principale (2), un rivet (16) étant introduit dans cet alésage à l'intérieur de la douille(7), ce rivet reliant la platine principale (2) et la plaque d'appui (10). La présente invention permet donc de réaliser un ensemble de plaquettes de frein, dans lequel la liaison entre le module de plaquette et la platine principale présente une structure aussi simple que possible, tout en étant fiable.
