Abstract
Description
La présente invention concerne une plaquette de friction pour frein à disque à guidages en .queue d'aronde dans une ouverture d'un étrier de frein. The present invention relates to a friction pad for a disc brake with dovetail guides in an opening of a brake caliper.
Ce type de frein d'un usage assez développé dans l'industrie automobile souffre cependant de divers défauts dus à l'insuffisance du guidage des plaquettes. Cette insuffisance résulte essentiellement de la faible épaisseur de la plaquette qui supporte la garniture de friction. De plus, la forme de queue d'aronde des zones de guidage dans la plaquette est obtenue par découpage, ce qui réduit encore l'épaisseur et produit un arrondissement des arêtes qui est nuisible également à la qualité de guidage. Ce mauvais guidage entraîne des risques de blocage, en particulier sous l'effet des vibrations produites dans le véhicule. This type of brake, which is fairly widely used in the automotive industry, however suffers from various faults due to insufficient guidance of the pads. This insufficiency results essentially from the small thickness of the plate which supports the friction lining. In addition, the dovetail shape of the guide zones in the plate is obtained by cutting, which further reduces the thickness and produces rounding of the edges which is also detrimental to the quality of guidance. This poor guidance entails risks of blockage, in particular under the effect of the vibrations produced in the vehicle.
La présente invention vise à améliorer le guidage des plaquettes de friction en augmentant la hauteur utile de guidage de la plaquette. The present invention aims to improve the guidance of friction pads by increasing the useful height of guide of the pad.
A cet effet, la plaquette selon l'invention est caractérisée par le fiait que les zones de guidage en queue d'aronde comportent une surépaisseur d'une seule pièce avec la plaquette. Cette surépaisseur augmente la hauteur utile de guidage et améliore ainsi considérablement la tenue des freins équipés de telles plaquettes. To this end, the wafer according to the invention is characterized by the fact that the dovetail guide zones have an additional thickness in one piece with the wafer. This extra thickness increases the useful guide height and thus considerably improves the resistance of the brakes fitted with such pads.
L'invention concerne également un procédé pour la fabrication de la plaquette de frein précédente, caractérisé par le fait que les zones en queue d'aronde munies d'une surépaisseur sont obtenues par matriçage à froid. Ce procédé offre l'avantage supplémentaire de produire un écrouissage du métal dans la zone matricée, clest-à-dire un durcissement superficiel de la zone de guidage qui améliore la tenue et la durée de la plaquette. The invention also relates to a method for manufacturing the previous brake pad, characterized in that the dovetail areas provided with an extra thickness are obtained by cold stamping. This method offers the additional advantage of producing a work hardening of the metal in the stamped zone, ie a surface hardening of the guide zone which improves the resistance and the duration of the insert.
L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel
- la figure 1 est une vue en plan d'une plaquette selon un exemple de réalisation de l'invention, et
- la figure. 2 est une vue en perspective de la plaquette de la figure 1. The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which
FIG. 1 is a plan view of a plate according to an exemplary embodiment of the invention, and
- the figure. 2 is a perspective view of the plate of FIG. 1.
On n'a pas représenté au dessin la garniture de friction qui est collée sur la plaquette 1. La plaquette 1 comporte deux oreilles latérales 2 ménageant chacune une en- coche en queue d'aronde 3. Chaque encoche 3 coulisse dans une fenêtre d'un étrier 4 dont le bord 5 a une forme complémentaire de celle de l'encoche 3, avec interposition éventuelle d'une clavette de guidage 6. The friction lining which is glued to the plate 1 has not been shown in the drawing. The plate 1 has two lateral ears 2 each providing a dovetail notch 3. Each notch 3 slides in a window of a stirrup 4 whose edge 5 has a shape complementary to that of the notch 3, with possible interposition of a guide key 6.
Conformément à l'invention, les encoches en queue d'aronde 3 sont surmontées par une surépaisseur 7 > obtenue par repoussage ou matriçage à froid. According to the invention, the dovetail notches 3 are surmounted by an extra thickness 7> obtained by embossing or cold stamping.
