DISPOSITIF DE FIXATION D'UN TUBE SUR UN SUPPORT, EN PARTICULIER DANS UN VEHICULE AUTOMOBILE.DEVICE FOR FIXING A TUBE ON A SUPPORT, PARTICULARLY IN A MOTOR VEHICLE.
L'invention concerne un dispositif de fixation d'un tube sur un support, en particulier d'un tube de transfert de fluide dans un compartiment moteur ou un dessous de caisse de véhicule automobile, au moyen d'une pièce montée autour du tube et d'une patte de fixation de cette pièce sur un support.The invention relates to a device for fixing a tube to a support, in particular a fluid transfer tube in an engine compartment or underbody of a motor vehicle, by means of a part mounted around the tube and a mounting lug for this part on a support.
Les tubes de transfert de fluide qui sont destinés à être montés dans un compartiment moteur ou un dessous de caisse de véhicule automobile, tels que des tubes de circuits de direction assistée, de freinage, de climatisation, de refroidissement, d'alimentation en carburant, etc.. sont pour la plupart fixés sur des supports en un point de leur longueur au moyen de dispositifs permettant non seulement de tenir et d'immobiliser les tubes, mais aussi d'assurer leur orientation dans une position angulaire prédéterminée autour de leur axe. On a dé] à proposé d'utiliser pour cela des pattes de fixation qui sont soudées sur les tubes à une de leurs extrémités et fixées sur un support par vissage par exemple à leur autre extrémité, mais les opérations de soudure (ou de brasure) des pattes sur les tubes sont coûteuses et peuvent conduire au perçage des tubes . On a également proposé de monter ces pattes de fixation sur les tubes par clipsage ou encliquetage élastique, ou de monter des pièces autour des tubes et de fixer ces pièces par clipsage ou encliquetage sur des pattes, mais cela oblige à former des méplats sur les tubes pour assurer une orientation angulaire déterminée des pattes ou des pièces sur les tubes et le blocage ou l'immobilisation en rotation des pattes ou des pièces sur les tubes.Fluid transfer tubes which are intended to be mounted in an engine compartment or underbody of a motor vehicle, such as tubes for power steering circuits, braking, air conditioning, cooling, fuel supply, etc ... are mostly fixed on supports at a point along their length by means of devices allowing not only to hold and immobilize the tubes, but also to ensure their orientation in a predetermined angular position around their axis. It has been proposed to use for this purpose fixing lugs which are welded to the tubes at one of their ends and fixed to a support by screwing, for example at their other end, but the welding (or brazing) operations tabs on the tubes are expensive and can lead to drilling the tubes. It has also been proposed to mount these fixing lugs on the tubes by clipping or snap-fastening, or to mount parts around the tubes and to fix these parts by clipping or snap-fastening on lugs, but this forces them to form flats on the tubes. to ensure a determined angular orientation of the legs or parts on the tubes and the blocking or immobilization in rotation of the legs or parts on the tubes.
Il est par ailleurs souhaitable que ces fixations ne génèrent pas de vibrations et ne permettent pas la transmission des bruits et des vibrations entre les supports et les tubes.It is also desirable that these fasteners do not generate vibrations and do not allow not the transmission of noise and vibrations between the supports and the tubes.
L'invention a pour objet un dispositif de fixation de tube qui répond à ces besoins sans présenter les inconvénients des moyens précités de la technique antérieure .The invention relates to a tube fixing device which meets these needs without having the drawbacks of the aforementioned means of the prior art.
Elle propose à cet effet un dispositif de fixation d'un tube sur un support, en particulier d'un tube de transfert de fluide pour véhicule automobile, comprenant une pièce montée autour du tube et une patte de fixation de cette pièce sur un support, caractérisé en ce que ladite pièce a une section transversale en U, en ce qu'une garniture en caoutchouc ou en une autre matière élastiquement déformable est interposée entre la pièce en U et le tube et en ce que la pièce en U est resserrée autour du tube par la patte de fixation en comprimant la garniture sur le tube.To this end, it provides a device for fixing a tube to a support, in particular a fluid transfer tube for a motor vehicle, comprising a part mounted around the tube and a lug for fixing this part to a support, characterized in that said part has a U-shaped cross-section, in that a rubber or other elastically deformable material lining is interposed between the U-shaped part and the tube and in that the U-shaped part is tightened around the tube by the fixing lug by compressing the gasket on the tube.
Un tel dispositif répond parfaitement au cahier des charges des constructeurs automobiles tout en ayant l'avantage d'une simplicité de montage sur le tube, réalisable sans outil particulier et à un coût moindre que dans la technique antérieure. De plus, la garniture en caoutchouc ou analogue empêche la transmission des bruits et des vibrations entre le tube et le support . Selon une autre caractéristique deSuch a device perfectly meets the specifications of car manufacturers while having the advantage of a simplicity of mounting on the tube, achievable without special tools and at a lower cost than in the prior art. In addition, the rubber lining or the like prevents the transmission of noise and vibrations between the tube and the support. According to another characteristic of
1 ' invention, la pièce en U précitée est montée sur la patte de fixation par clipsage ou encliquetage élastique et comprend au moins une extrémité engagée et retenue par élasticité dans un orifice de la patte de fixation. Selon encore d'autres caractéristiques de1 invention, the aforementioned U-shaped part is mounted on the fixing lug by clipping or elastic snap-fastening and comprises at least one end engaged and retained by elasticity in an orifice of the fixing lug. According to still other characteristics of
1 ' invention, la garniture précitée est surmoulée sur une armature métallique ou en matière plastique et forme également au moins une partie de la surface extérieure de la pièce en U. Ainsi, la garniture fait partie intégrante de la pièce en U, ce qui facilite les manipulations, réduit le nombre de pièces, facilite le montage, etc.. et la pièce en U recouverte par la garniture de caoutchouc ou analogue peut être amenée en contact avec un autre élément à l'intérieur du compartiment moteur sans générer de bruits, de chocs ou de vibrations.1 invention, the aforementioned packing is overmolded on a metal frame or plastic and also forms at least a portion of the outer surface of the U-shaped part. handling, reduced the number of parts, facilitates assembly, etc. and the U-shaped part covered by the rubber lining or the like can be brought into contact with another element inside the engine compartment without generating noise, shock or vibrations.
L'invention sera mieux comprise et d'autres caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui suit, faite à titre d'exemple en référence aux dessins annexés dans lesquels :The invention will be better understood and other characteristics, details and advantages thereof will appear more clearly on reading the description which follows, given by way of example with reference to the appended drawings in which:
- la figure 1 est une vue schématique en coupe transversale d'un dispositif selon l'invention avant son montage sur un tube de transfert de fluide ;- Figure 1 is a schematic cross-sectional view of a device according to the invention before it is mounted on a fluid transfer tube;
- la figure 2 est une vue de côté de la pièce en U de ce dispositif ;- Figure 2 is a side view of the U-shaped part of this device;
- la figure 3 est une vue schématique en coupe transversale représentant le dispositif monté sur un tube et sur un support .- Figure 3 is a schematic cross-sectional view showing the device mounted on a tube and on a support.
Le dispositif selon l'invention, dont un mode de réalisation préféré est représenté aux figures 1 à 3, est destiné à fixer un tube 10 de transfert de fluide sur un support 12, par exemple dans un compartiment moteur de véhicule automobile, et comprend une pièce 14 en U montée autour du tube 10 et une patte rigide 16 (de préférence métallique et avantageusement en aluminium) pour la fixation de la pièce 14 sur le support 12 au moyen d'un boulon 18, d'un système vis-écrou ou analogue.The device according to the invention, a preferred embodiment of which is shown in FIGS. 1 to 3, is intended to fix a fluid transfer tube 10 on a support 12, for example in an engine compartment of a motor vehicle, and comprises a U-shaped part 14 mounted around the tube 10 and a rigid tab 16 (preferably metallic and advantageously made of aluminum) for fixing the part 14 to the support 12 by means of a bolt 18, of a screw-nut system or similar.
Le tube 10 peut être métallique ou rigide à structure multicouches ou composite et fait partie d'un circuit de fluide dans lequel sont susceptibles d'être engendrés des bruits, des vibrations, etc.The tube 10 can be metallic or rigid with a multilayer or composite structure and is part of a fluid circuit in which noise, vibrations, etc. are liable to be generated.
La pièce en U 14 comprend une armature 20 en matière relativement rigide, par exemple en métal ou en matière plastique, recouverte au moins partiellement d'une garniture 22 de caoutchouc ou d'une autre matière élastiquement déformable interposée entre l'armature 20 et le tube 10 pour empêcher la transmission des bruits et des vibrations entre le tube 10 et le support 12.The U-shaped part 14 comprises a frame 20 made of relatively rigid material, for example metal or plastic, covered at least partially with a lining 22 of rubber or of another elastically deformable material interposed between the frame 20 and the tube 10 to prevent the transmission of noise and vibrations between the tube 10 and the support 12.
Avantageusement, la garniture 22 est surmoulée sur l'armature 20 qui comporte de place en place des orifices 24 permettant un meilleur ancrage de l'armature 20 dans la garniture 22, celle-ci recouvrant au moins une partie de la surface extérieure de l'armature 20 pour amortir les chocs et les vibrations au contact d'autres objets se trouvant au voisinage immédiat de la pièce en U 14.Advantageously, the liner 22 is overmolded on the frame 20 which has from place to place orifices 24 allowing better anchoring of the frame 20 in the liner 22, the latter covering at least a portion of the outer surface of the armature 20 to absorb shock and vibration on contact with other objects in the immediate vicinity of the U-shaped part 14.
Les deux extrémités 26 de l'armature 20 sont repliées vers l'extérieur et forment des rebords latéraux de clipsage ou d ' encliquetage élastique dans des orifices 28 de la plaque 16. Avantageusement et comme représenté en figureThe two ends 26 of the frame 20 are folded outwards and form lateral edges for snap-fastening or snap-fastening in orifices 28 in the plate 16. Advantageously and as shown in the figure
1, les rebords latéraux des extrémités 26 de l'armature 20 forment des rampes inclinées convergentes sur lesquelles peuvent glisser les bords des orifices 28 de la patte 16. A l'état libre, la pièce en U 14 a un diamètre interne (diamètre de la garniture 22) légèrement supérieur au diamètre extérieur du tube 10 et la distance entre les rebords des extrémités 26 de l'armature 20 est légèrement supérieure à la distance D entre les bords opposés des orifices 28 de la patte 16 de telle sorte que, quand la pièce en U 14 est montée sur la patte 16 comme représenté en figure 3, la garniture 22 est comprimée élastiquement sur le tube 10 et entre ce tube et la patte 16 par les extrémités de l'armature 20 qui ont été rapprochées et qui sont en appui sur les bords des orifices 28.1, the lateral edges of the ends 26 of the frame 20 form convergent inclined ramps on which the edges of the orifices 28 of the tab can slide. In the free state, the U-shaped part 14 has an internal diameter (diameter of the lining 22) slightly greater than the outside diameter of the tube 10 and the distance between the edges of the ends 26 of the frame 20 is slightly greater than the distance D between the opposite edges of the orifices 28 of the tab 16 so that, when the U-shaped part 14 is mounted on the lug 16 as shown in FIG. 3, the lining 22 is elastically compressed on the tube 10 and between this tube and the lug 16 by the ends of the frame 20 which have been brought together and which are resting on the edges of the orifices 28.
Pour le montage du dispositif selon l'invention, on peut disposer la pièce en U 14 autour du tube 10 comme représenté en figure 1, puis resserrer à la main ou à l'aide d'une pince la pièce en U 14 sur le tube 10, amener la patte 16 avec ses orifices 28 en regard des extrémités de l'armature 20 et engager ces extrémités dans les orifices 28 jusqu'à clipsage ou encliquetage élastique, la patte 16 étant alors appliquée sur la garniture 22. La compression de la garniture 22 sur le tubeFor mounting the device according to the invention, the U-shaped part 14 can be placed around the tube 10 as shown in FIG. 1, then tighten the U-shaped part 14 by hand or with pliers on the tube 10, bring the tab 16 with its orifices 28 opposite the ends of the frame 20 and engage these ends in the orifices 28 until snap-fastening or snap-fastening, the tab 16 is then applied to the lining 22. The compression of the lining 22 on the tube
10 est déterminée pour immobiliser la pièce en U 14 en translation et en rotation sur le tube 10. On peut pour cela prévoir un réseau de nervures en saillie sur la surface interne de la garniture 22, ces nervures en saillie pouvant se croiser entre elles et être formées par deux filetages de sens opposés comme décrit dans la Demande de brevet français 97 08856 de la demanderesse, dont le contenu est incorporé ici par référence.10 is determined to immobilize the U-shaped part 14 in translation and in rotation on the tube 10. For this purpose, it is possible to provide a network of protruding ribs on the internal surface of the lining 22, these protruding ribs being able to cross between them and be formed by two threads in opposite directions as described in French patent application 97 08856 of the applicant, the content of which is incorporated herein by reference.
On peut également, pour monter la patte 16 sur la pièce en U 14, engager ses orifices 28 sur les extrémités repliées 26 de l'armature 20 et pousser la patte 16 sur la pièce en U 14 ce qui a pour conséquence, par effet de rampes inclinées, de rapprocher l'une de l'autre les extrémités 26 de l'armature 20 jusqu'à ce que ces extrémités 26 sortent des orifices 28 et se bloquent sur la patte 16 par encliquetage.It is also possible, to mount the tab 16 on the U-shaped part 14, engage its orifices 28 on the folded ends 26 of the frame 20 and push the tab 16 on the U-shaped part 14 which has the consequence, by effect of inclined ramps, to bring the ends 26 of the frame 20 closer to one another until these ends 26 come out of the orifices 28 and lock on the tab 16 by snap-fastening.
La dureté du caoutchouc ou de l'élastomère de la garniture 22 et son serrage sur le tube 10 et sur la patte 16 sont déterminés en fonction des bruits et des vibrations qui sont générés dans le tube 10 et dont il faut empêcher la transmission au support 12.The hardness of the rubber or of the elastomer of the lining 22 and its tightening on the tube 10 and on the tab 16 are determined as a function of the noises and vibrations which are generated in the tube 10 and which must be prevented from being transmitted to the support. 12.
Bien qu'il soit préférable que la garniture 22 soit surmoulée sur l'armature 20, la pièce en U 14 pourrait être remplacée par une bague fendue de caoutchouc ou d'elastomere que l'on placerait sur le tube 10 et sur laquelle on viendrait disposer l'armature 20.Although it is preferable that the lining 22 is overmolded on the frame 20, the U-shaped part 14 could be replaced by a split ring of rubber or elastomer which would be placed on the tube 10 and on which one would come arrange the frame 20.
Les moyens de clipsage ou d' encliquetage élastique de l'armature 20 sur la patte 16 peuvent également être différents de ceux représentés : par exemple, la patte 16 pourrait comprendre un seul orifice 28 dont la dimension dans le plan du dessin serait la distance D représentée en figure 1. Par ailleurs, les extrémités de l'armature 20 pourraient avoir des formes différentes, l'une comprenant par exemple un rebord en L qui viendrait s'appliquer sur la face supérieure de la patte 16 et l'autre ayant la forme représentée au dessin pour fixation de la pièce 14 sur la patte 16 par clipsage ou encliquetage élastique.The means for clipping or elastic snap-fitting of the armature 20 onto the tab 16 may also be different from those shown: for example, the tab 16 could comprise a single orifice 28 whose dimension in the plane of the drawing would be distance D shown in FIG. 1. Furthermore, the ends of the frame 20 could have different shapes, one comprising for example an L-shaped flange which would be applied to the upper face of the tab 16 and the other having the shape shown in the drawing for fixing the part 14 to the lug 16 by clipping or elastic snap-fastening.
Selon une autre variante, les extrémités de l'armature 20 pourraient également être formées avec des rebords en L orientés vers l'extérieur, qui viendraient s'engager sur les bord des orifices 28 ou s'accrocher sur des languettes formées par des crevés de la patte 16.According to another variant, the ends of the frame 20 could also be formed with L-shaped flanges facing outwards, which would engage on the edges of the orifices 28 or hang on tabs formed by punctures of paw 16.
Le dispositif qui a été décrit et représenté en dessin est évidemment démontable, par rapprochement des extrémités 26 de l'armature 20 et passage de ces extrémités à travers les orifices 28 de la patte 16.The device which has been described and shown in the drawing is obviously removable, by bringing the ends 26 of the frame 20 together and passing these ends through the orifices 28 in the tab 16.
Ce dispositif peut aussi être rendu indémontable, par exemple par écrasement ou aplatissement des extrémités 26 vers l'intérieur ou vers l'extérieur. L'invention concerne en particulier la fixation des tubes de transfert de fluide dans un compartiment moteur ou sur un dessous de caisse de véhicule automobile, mais est de façon générale applicable à la fixation des tubes, tuyaux et canalisations de tous types sur des supports. This device can also be made non-removable, for example by crushing or flattening the ends 26 inward or outward. The invention relates in particular to the fixing of the fluid transfer tubes in an engine compartment or on an underbody of a motor vehicle, but is generally applicable to the fixing of tubes, pipes and conduits of all types on supports.
