Abstract
Description
L'invention se rapporte à un protecteur de disque de frein de véhicule automobile ainsi qu'à un procédé de réalisation d'un tel protecteur. The invention relates to a motor vehicle brake disc protector as well as to a method for producing such a protector.
Pour protéger les pistes de freinage du disque d'un frein à disque contre les projections d'eau, de boue ou autre, il est connu de fixer sur l'essieu du véhicule un protecteur de disque. Classiquement, le protecteur est constitué d'une feuille de tôle emboutie qui est fixée au niveau de sa partie centrale par une pluralité de vis. To protect the disc braking tracks of a disc brake against splashing water, mud or the like, it is known to attach a disc protector to the axle of the vehicle. Conventionally, the protector consists of a stamped sheet metal sheet which is fixed at its central part by a plurality of screws.
Les vibrations engendrées par le train du véhicule lors du roulage entraînent fréquemment une détérioration du protecteur, notamment au niveau de ses points de fixation sur l'essieu. En particulier, la portion de tôle du protecteur qui est prise en sandwich au niveau des têtes de vis de fixation a tendance à se découper. Pour résoudre ce problème, il est connu de souder une pièce de renfort sur le protecteur au niveau des orifices prévus pour le passage des vis. The vibrations generated by the train of the vehicle during running frequently cause deterioration of the guard, in particular at the level of its fixing points on the axle. In particular, the portion of sheet metal of the protector which is sandwiched at the level of the fixing screw heads tends to cut out. To solve this problem, it is known to weld a reinforcement piece on the protector at the orifices provided for the passage of the screws.
Cependant, ce procédé de renforcement du protecteur s'avère coûteux, en raison notamment de la nécessité de d'effectuer une opération de soudage d'une pièce rapportée. However, this method of reinforcing the protector turns out to be expensive, in particular because of the need to carry out an operation of welding an added part.
Un but de la présente invention est de proposer un protecteur de disque de frein de véhicule automobile palliant tout ou partie des inconvénients de l'art antérieur relevés ci- dessus. An object of the present invention is to provide a motor vehicle brake disc protector which overcomes all or part of the drawbacks of the prior art noted above.
Ce but est atteint par le fait que le protecteur de disque de frein de véhicule automobile est constitué d'une feuille métallique de forme générale circulaire comportant une découpe sur sa périphérie destinée à ménager un espace pour un étrier d'un système de freinage, la partie centrale du protecteur comportant une ouverture délimitée par un bord pourvu d'au au moins un orifice prévu pour le passage d'un élément de fixation du type vis, le bord de l'ouverture comportant des moyens de renforcement disposés au moins au niveau du ou des orifices, les moyens de renforcement étant constitués par au moins un repliement local du bord. This object is achieved by the fact that the motor vehicle brake disc protector consists of a metal sheet of generally circular shape comprising a cutout on its periphery intended to provide space for a caliper of a braking system, the central part of the protector comprising an opening delimited by an edge provided with at least one orifice provided for the passage of a fixing element of the screw type, the edge of the opening comprising reinforcement means arranged at least at the level of the or orifices, the reinforcement means being constituted by at least one local folding of the edge.
Par ailleurs, l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes - le bord de l'ouverture est replié sensiblement sur toute sa circonférence, - le bord de l'ouverture comporte un repliement, de façon à présenter localement une épaisseur de matière double par rapport au reste du corps du protecteur, - le bord de l'ouverture comporte deux repliements de façon à présenter localement une épaisseur de matière triple par rapport au reste du corps du protecteur. Furthermore, the invention may include one or more of the following characteristics - the edge of the opening is folded substantially over its entire circumference, - the edge of the opening comprises a folding, so as to locally have a thickness of material double compared to the rest of the body of the protector, - the edge of the opening has two folds so as to locally present a thickness of material triple compared to the rest of the body of the protector.
Un autre but de la présente invention est de proposer un procédé de réalisation d'un protecteur de disque de frein conforme à l'une ou plusieurs des caractéristiques ci-dessus. Another object of the present invention is to provide a method for producing a brake disc protector conforming to one or more of the above characteristics.
Ce but est atteint par le fait que le procédé de réalisation d'un protecteur de disque de frein consistant à emboutir une feuille métallique, comporte au moins une étape de pliage de la portion de la feuille constituant le bord de l'ouverture centrale, le ou les orifices étant usinés après l'étape de pliage. This object is achieved by the fact that the method of producing a brake disc protector consisting of stamping a metal sheet, comprises at least one step of folding the portion of the sheet constituting the edge of the central opening, the or the holes being machined after the folding step.
D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence aux figures dans lesquelles - la figure 1 représente une vue en perspective d'un protecteur de disque de frein de l'art antérieur, - la figure 2 représente une section du protecteur de la figure 1, fixé sur un élément d'un essieu de véhicule, - la figure 3 représente un détail d'une section d'un protecteur selon l'invention illustrant son montage sur un élément d'un essieu de véhicule, - la figure 4 représente un détail d'une section d'un protecteur conforme à un second mode de réalisation de l'invention. Other features and advantages will appear on reading the description below, made with reference to the figures in which - Figure 1 shows a perspective view of a brake disc protector of the prior art, - Figure 2 represents a section of the protector of FIG. 1, fixed on an element of a vehicle axle, - FIG. 3 represents a detail of a section of a protector according to the invention illustrating its mounting on an element of a vehicle axle, - Figure 4 shows a detail of a section of a protector according to a second embodiment of the invention.
La figure 1 représente un protecteur 1 de disque de frein de type connu, constitué d'une feuille métallique de forme générale circulaire. Le protecteur 1 comporte une découpe 2 sur sa périphérie destinée à ménager un espace pour un étrier d'un système de freinage (non représenté). Figure 1 shows a brake disc protector 1 of known type, consisting of a metal sheet of generally circular shape. The protector 1 has a cutout 2 on its periphery intended to provide space for a caliper of a braking system (not shown).
La partie centrale du protecteur 1 est emboutie de façon à former une portion tubulaire de forme générale tronconique dont l'extrémité comporte une ouverture 3. L'ouverture 3 est délimitée par un bord 4 pourvu de quatre orifices 5 prévus pour le passage de vis de fixation 7 respectives (figure 2). Par ailleurs, une languette métallique 10 de renforcement ayant une forme générale en U est soudée sur le bord 4, de façon à renforcer toute la circonférence du bord 4. The central part of the protector 1 is stamped so as to form a tubular portion of generally frustoconical shape, the end of which has an opening 3. The opening 3 is delimited by an edge 4 provided with four orifices 5 provided for the passage of respective fixing 7 (figure 2). Furthermore, a metal reinforcement tab 10 having a general U-shape is welded to the edge 4, so as to reinforce the entire circumference of the edge 4.
La figure 2 illustre la fixation du protecteur 1 sur un élément de la structure 11 d'un véhicule, tel qu'un bras de suspension ou un pivot par exemple. Le protecteur 1 est maintenu sur l'élément 11 par coincement du bord 4 entre le corps de l'élément 11 et les têtes des vis 7 de fixation. FIG. 2 illustrates the attachment of the protector 1 to an element of the structure 11 of a vehicle, such as a suspension arm or a pivot for example. The protector 1 is held on the element 11 by wedging the edge 4 between the body of the element 11 and the heads of the fixing screws 7.
La figure 3 représente une section d'un détail du bord 4 de l'ouverture centrale d'un protecteur 1 conforme à l'invention. Selon l'invention, l'extrémité de la feuille métallique constituant le bord 4 de l'ouverture centrale du protecteur 1 est repliée sur elle-même 6, 8. Ainsi, le bord 4 central du protecteur 1 présente localement une épaisseur de matière double par rapport au reste de son corps. Ainsi, les portions du protecteur 1 qui sont serrées entre l'élément de l'essieu 11 et les têtes des vis 7 se trouvent renforcées. Le bord peut être plié uniquement au niveau des emplacements des orifices 5 prévus pour les vis 7, cependant, de préférence, le bord 4 de l'ouverture 3 est replié sensiblement sur toute sa circonférence.Figure 3 shows a section of a detail of the edge 4 of the central opening of a protector 1 according to the invention. According to the invention, the end of the metal sheet constituting the edge 4 of the central opening of the protector 1 is folded back on itself 6, 8. Thus, the central edge 4 of the protector 1 locally has a thickness of double material compared to the rest of his body. Thus, the portions of the protector 1 which are clamped between the element of the axle 11 and the heads of the screws 7 are reinforced. The edge can be folded only at the locations of the holes 5 provided for the screws 7, however, preferably, the edge 4 of the opening 3 is folded substantially over its entire circumference.
La figure 4 représente une variante de réalisation de l'invention qui se distingue de la forme de réalisation de la figure 3 par le fait que le bord 4 comporte deux repliement 8, 9 au lieu d'un seul 8. C'est-à-dire que le bord 4 de l'ouverture est plié deux fois, de façon à présenter localement une épaisseur de matière triple par rapport au reste du corps du protecteur 1. 4 shows an alternative embodiment of the invention which differs from the embodiment of Figure 3 in that the edge 4 has two folds 8, 9 instead of a single 8. That is to say say that the edge 4 of the opening is folded twice, so as to locally present a thickness of material triple with respect to the rest of the body of the protector 1.
On conçoit donc aisément que le protecteur 1 conforme à l'invention, tout en étant de structure simple, présente une bonne solidité dans son montage. Par ailleurs, le protecteur 1 selon l'invention peut être réalisé d'une manière simple et économique. En effet, le ou les pliages du bord 4 peuvent être réalisés lors de l'opération d'emboutissage de la feuille de tôle constituant le protecteur 1. Le ou les orifices 5 prévus pour les vis 7 peuvent être usinés après l'étape de pliage, par exemple par perçage ou poinçonnage. It is therefore easily understood that the protector 1 according to the invention, while being of simple structure, has good solidity in its mounting. Furthermore, the protector 1 according to the invention can be produced in a simple and economical manner. Indeed, the bending or bending of the edge 4 can be carried out during the stamping operation of the sheet metal sheet constituting the protector 1. The or orifices 5 provided for the screws 7 can be machined after the folding step , for example by drilling or punching.
Enfin, bien que l'invention ait été décrite en liaison avec des modes de réalisation particuliers, elle comprend tous les équivalents techniques des moyens décrits. Finally, although the invention has been described in connection with particular embodiments, it includes all the technical equivalents of the means described.
