Description

Disque de frein pour véhicule automobile Brake disc for a motor vehicle

L'invention relève du domaine des éléments constitutifs de frein pour un véhicule automobile. Elle a pour objet un disque de frein pour un véhicule automobile. 5 Le document WO 02/31376 (SONG Mun-Gu et al.) décrit un disque de frein pour un véhicule automobile. Le disque de frein comprend un corps de frein interposé entre deux plaques de frein. Le corps de frein est réalisé en un alliage d'aluminium. Les plaques de frein sont réalisées en fonte ou en un matériau non 10 ferreux. Les plaques de freins sont rapportées par des moyens d'assemblage sur le corps de frein. Les moyens d'assemblage sont constitués de moyens de vissage. The invention relates to the field of brake components for a motor vehicle. It relates to a brake disc for a motor vehicle. WO 02/31376 (SONG Mun-Gu et al.) Discloses a brake disc for a motor vehicle. The brake disc comprises a brake body interposed between two brake plates. The brake body is made of an aluminum alloy. The brake plates are made of cast iron or a non-ferrous material. The brake plates are reported by means of assembly on the brake body. The assembly means consist of screwing means.

Un tel disque de frein mérite d'être optimisé pour être plus léger, plus robuste et 15 plus rapide à assembler. Such a brake disk deserves to be optimized to be lighter, more robust and faster to assemble.

Le but de la présente invention est de proposer un disque de frein d'un véhicule automobile qui est léger, robuste, facile à réaliser. The object of the present invention is to provide a brake disc of a motor vehicle which is light, robust, easy to achieve.

20 Un disque de la présente invention est un disque de frein destiné à équiper un véhicule automobile. Le disque de frein comprend un corps de frein interposé entre deux plaques de frein. Le corps de frein et chaque plaque de frein sont assemblés par des moyens d'assemblage. A disc of the present invention is a brake disc for equipping a motor vehicle. The brake disc comprises a brake body interposed between two brake plates. The brake body and each brake plate are assembled by means of assembly.

25 Selon la présente invention, les moyens d'assemblage sont constitués de moyens d'emboîtement. According to the present invention, the assembly means consist of interlocking means.

Les moyens d'assemblage comprennent par exemple au moins un picot et au moins un orifice de géométrie complémentaire. Selon une variante, le picot est ménagé sur chaque plaque de frein tandis que l'orifice est ménagé sur le corps de frein. 30 Les picots et les orifices étant en pluralité, les picots et les orifices sont avantageusement symétriquement répartis par rapport à un axe de symétrie du disque de frein. Selon une forme de réalisation, l'orifice reçoit des picots de chaque plaque de frein. The assembly means comprise for example at least one pin and at least one orifice of complementary geometry. Alternatively, the pin is formed on each brake plate while the orifice is formed on the brake body. The pins and the orifices being in a plurality, the pins and the orifices are advantageously symmetrically distributed with respect to an axis of symmetry of the brake disc. According to one embodiment, the orifice receives pins from each brake plate.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la 10 lecture de la description qui va en être faite d'exemples de réalisation, en relation avec les figures de la planche annexée, dans laquelle : La figure 1 est une vue schématique en perspective éclatée d'un disque de frein de la présente invention. La figure 2 est une vue en coupe transversale du disque de frein représenté sur la 15 figure 1. Other features and advantages of the present invention will appear on reading the description which will be made of exemplary embodiments, in relation to the figures of the attached plate, in which: FIG. 1 is a diagrammatic view of exploded perspective of a brake disk of the present invention. Figure 2 is a cross-sectional view of the brake disc shown in Figure 1.

Sur les figures, un disque de frein 1 comprend un corps de frein 2 interposé entre deux plaques de frein 3. Le corps de frein 2 est globalement conformé en une galette plane et circulaire d'axe de symétrie Al. Autrement dit, chaque face du 20 corps de frein 2 reçoit une plaque de frein 3. Le corps de frein 2 est réalisé en un alliage léger, aluminium notamment. Les plaques de frein 3 sont chacune conformées en un anneau circulaire d'axe de révolution A2 qui est préférentiellement confondu avec l'axe de symétrie Al. Les plaques de frein 3 sont chacune réalisées en un matériau de friction, fonte notamment. Le matériau 25 de friction est apte à résister à une usure provoquée par un contact avec des plaquettes de frein non représentées sur les figures. In the figures, a brake disc 1 comprises a brake body 2 interposed between two brake plates 3. The brake body 2 is generally shaped in a plane and circular slab of axis of symmetry A1. In other words, each face of the brake disk 1 20 brake body 2 receives a brake plate 3. The brake body 2 is made of a light alloy, including aluminum. The brake plates 3 are each shaped into a circular ring of axis of revolution A2 which is preferably merged with the axis of symmetry A1. The brake plates 3 are each made of a friction material, including cast iron. The friction material 25 is able to withstand wear caused by contact with brake pads not shown in the figures.

Les plaques de frein 3 sont rapportées sur le disque de frein 2 par des moyens d'assemblage 4. Les moyens d'assemblage 4 de la présente invention sont 30 avantageusement constitués de moyens d'emboîtement 4. Ces derniers sont constitués d'organes complémentaires d'emboitement tels qu'au moins un couple de picot circulaire 5 et d'orifice circulaire 6, ou tout autre organe complémentaire5 d'emboitement analogue. Le picot circulaire 5 et l'orifice circulaire 6 sont ménagés sur des faces en regard l'une de l'autre du corps de frein 2 et de chaque plaque de frein 3. The brake plates 3 are attached to the brake disk 2 by means of assembly 4. The assembly means 4 of the present invention advantageously consist of interlocking means 4. The latter consist of complementary members interlocking such as at least a pair of circular pin 5 and circular orifice 6, or any other complementary member 5 of similar interlocking. The circular pin 5 and the circular orifice 6 are formed on opposite faces of each other of the brake body 2 and of each brake plate 3.

Selon une variante préférée de réalisation, les moyens d'emboîtement 4 comprennent une pluralité de couples de picot circulaire 5 et d'orifice circulaire 6. According to a preferred embodiment, the interlocking means 4 comprise a plurality of pairs of circular pin 5 and circular orifice 6.

Selon une première variante, les picots circulaires 5 sont ménagés sur les plaques de frein 3 tandis que les orifices circulaires 6 sont ménagés sur le corps de frein 2, tel qu'illustré sur la figure unique. Selon une deuxième variante, les picots circulaires sont ménagés sur le corps de frein tandis que les orifices circulaires sont ménagés sur les plaques de frein. In a first variant, the circular pins 5 are formed on the brake plates 3 while the circular holes 6 are formed on the brake body 2, as shown in the single figure. In a second variant, the circular pins are formed on the brake body while the circular holes are formed on the brake plates.

Préférentiellement, un même orifice circulaire 6 du corps de frein 2 reçoit des picots circulaires 5 de chaque plaque de frein 3. Preferably, the same circular orifice 6 of the brake body 2 receives circular pins 5 of each brake plate 3.

Ces dispositions sont telles qu'aucun élément supplémentaire du type vis, boulon, écrou ou analogue n'est utile pour l'assemblage entre eux du corps de frein 2 et des plaques de frein 3. Il en résulte un gain de poids pour le disque de frein 1. A titre de comparaison, un disque de frein 1 de la présente invention présente par exemple une masse de 5,5 kg alors qu'un disque monobloc en fonte de l'art antérieur et de dimension identique présente une masse de 10 kg, la présente invention procurant un gain de masse de 45°/O. Il en résulte consécutivement une diminution d'émission de dioxyde de carbone pour un véhicule automobile pourvu d'un tel disque de frein 1. These arrangements are such that no additional element of the type screw, bolt, nut or the like is useful for the assembly between them of the brake body 2 and the brake plates 3. This results in a weight saving for the disc As a comparison, for example, a brake disc 1 of the present invention has a mass of 5.5 kg, whereas a cast iron monoblock disc of the prior art of identical size has a mass of 10 kg. kg, the present invention providing a mass gain of 45%. This results, consecutively, in a reduction of carbon dioxide emission for a motor vehicle provided with such a brake disc 1.

Un tel disque de frein 1 est finalement plus léger, plus robuste et plus facile à assembler qu'un disque de frein de l'art antérieur. Such a brake disc 1 is ultimately lighter, more robust and easier to assemble than a prior art brake disc.
