Description

PALIER DE BARRE ANTI-DEVERS DE VEHICULE AUTOMOBILE, COMPRENANT UNE BRIDE EN APPUI SUR UNE PARTIE CYLINDRIQUE  AUTOMOTIVE VEHICLE ANTI-DEVICE BAR BEARING, COMPRISING A SUPPORTING FLANGE ON A CYLINDRICAL PART
La présente invention concerne un système de palier de barre anti- devers pour un train roulant d'un véhicule automobile, ainsi qu'un véhicule automobile équipé d'un tel système de palier. The present invention relates to a system of anti-roll bar bearing for a running gear of a motor vehicle, and a motor vehicle equipped with such a bearing system.
Les véhicules automobiles comportent généralement sur le train avant ou arrière, une barre anti-devers comprenant une partie centrale disposée transversalement, qui est fixée à ses extrémités sous la caisse du véhicule par deux systèmes de palier pour pivoter suivant l'axe de ces paliers. La partie centrale de la barre anti-devers se prolonge de chaque côté après le palier, par une partie coudée dont l'extrémité est reliée à un élément de la suspension.  The motor vehicles generally comprise on the front or rear axle, an anti-roll bar comprising a central portion disposed transversely, which is fixed at its ends under the vehicle body by two bearing systems to rotate along the axis of these bearings. The central part of the anti-roll bar is extended on each side after the bearing, by a bent part whose end is connected to a suspension element.
De cette manière quand le débattement de la suspension entre les deux côtés du train du véhicule est différent, la partie centrale de la barre anti- devers est soumise à une déformation élastique générant un couple de torsion qui tend à rappeler ces deux suspensions dans une position similaire.  In this way when the travel of the suspension between the two sides of the vehicle train is different, the central portion of the anti-roll bar is subjected to an elastic deformation generating a torque that tends to recall these two suspensions in a position similar.
On réalise ainsi une fonction anti-devers qui limite notamment les inclinaisons de la caisse du véhicule dans les virages. La barre anti-devers améliore le confort ainsi que la tenue de route du véhicule.  This provides an anti-roll function that limits the inclinations of the vehicle body in turns. The anti-roll bar improves the comfort and handling of the vehicle.
Un type de système de palier connu, présenté notamment par le document FR-A1 -2574886, comporte une bride en tôle ayant une forme cintrée, qui recouvre un palier en élastomère comprenant un perçage transversal recevant la barre anti-devers.  One type of known bearing system, presented in particular by the document FR-A1 -2574886, comprises a sheet metal flange having a curved shape, which covers an elastomeric bearing comprising a transverse bore receiving the anti-roll bar.
Une extrémité de la bride se termine par une patte insérée dans une fente de la tôle d'un berceau du train roulant du véhicule, qui forme une articulation permettant à cette bride de pivoter autour de sa patte. L'autre extrémité de la bride est serrée par un moyen de serrage comprenant une vis ajustée dans un perçage circulaire de cette extrémité et du berceau, ce qui réalise un blocage du palier en élastomère entre la partie centrale de cette bride et le berceau. Toutefois, on constate que certains paliers sont bruyants lorsque des efforts importants sont appliqués sur la barre anti-devers, le contact entre la patte de la bride et la fente de la tôle du berceau, sur une surface très réduite formée par une arrête de la tôle de ce berceau, pouvant émettre des claquements lors du débattement de la barre anti-devers. One end of the flange terminates with a tab inserted into a slot in the metal plate of a cradle of the vehicle undercarriage, which forms a hinge allowing this flange to pivot about its paw. The other end of the flange is clamped by a clamping means comprising a screw fitted in a circular bore of this end and the cradle, which makes a blocking of the elastomer bearing between the central portion of this flange and the cradle. However, it is found that some bearings are noisy when significant forces are applied on the anti-roll bar, the contact between the tab of the flange and the slot of the plate of the cradle, on a very small surface formed by a stop of the sheet metal of this cradle, which can issue clicks during the movement of the anti-roll bar.
La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.  The present invention is intended to avoid these disadvantages of the prior art.
Elle propose à cet effet un système de palier pour une barre anti-devers comportant un berceau lié à la caisse d'un véhicule, et une bride comprenant à une extrémité une patte d'indexage pouvant pivoter autour d'un point de fixation sur ce berceau, et à l'autre extrémité un moyen de serrage sur le berceau afin de bloquer le palier entre la partie centrale de la bride et ce berceau, caractérisé en ce que le point de fixation sur le berceau comporte une partie cylindrique de guidage disposée parallèlement à l'axe de rotation de la barre anti-devers, la patte d'indexage de la bride prenant appui sur cette partie cylindrique par une courbure ajustée dessus.  It proposes for this purpose a bearing system for an anti-roll bar having a cradle connected to the body of a vehicle, and a flange comprising at one end an indexing tab pivotable about a fixing point on it. cradle, and at the other end a clamping means on the cradle to block the bearing between the central portion of the flange and the cradle, characterized in that the attachment point on the cradle comprises a cylindrical guide portion disposed in parallel to the axis of rotation of the anti-roll bar, the indexing tab of the flange bearing on this cylindrical portion by a curvature fitted on it.
Un avantage du système de palier suivant l'invention, est que le contact entre la patte d'indexage de la bride et le support se faisant sur une surface importante grâce à la courbure de cette patte ajustée sur la partie cylindrique du point de fixation, permet de réaliser un appui qui n'émet pas de bruit lorsqu'il se déplace légèrement sous l'effet de contraintes importantes appliquées par la barre anti-devers.  An advantage of the bearing system according to the invention is that the contact between the indexing tab of the flange and the support being made over a large area thanks to the curvature of this lug fitted on the cylindrical portion of the attachment point, allows a support that does not emit noise when it moves slightly under the effect of significant stresses applied by the anti-roll bar.
Le système de palier selon l'invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.  The bearing system according to the invention may further comprise one or more of the following features, which may be combined with each other.
Selon un mode de réalisation, la partie cylindrique de guidage est comprise dans un profilé obtenu directement par filage d'un alliage léger.  According to one embodiment, the cylindrical guide portion is comprised in a profile obtained directly by spinning a light alloy.
Avantageusement, la patte de la bride est insérée dans une fente horizontale usinée dans le profilé juste en dessous de la partie cylindrique de guidage. Selon un autre mode de réalisation, le berceau comporte un bossage cylindrique transversal comprenant un perçage axial, obtenu directement par filage d'un alliage léger, ce perçage recevant un axe qui constitue la partie cylindrique de guidage disposée parallèlement à l'axe de rotation de la barre anti-devers. Advantageously, the tab of the flange is inserted into a horizontal slot machined in the section just below the cylindrical guide portion. According to another embodiment, the cradle comprises a transverse cylindrical boss comprising an axial bore, obtained directly by spinning a light alloy, this bore receiving an axis which constitutes the cylindrical guide portion disposed parallel to the axis of rotation of the the anti-roll bar.
Avantageusement, le berceau comporte une traverse obtenue par filage, recevant de chaque côté un bloc en élastomère posé sur le dessus formant le palier de la barre anti-devers, et un support avant obtenu par filage et fixé à cette traverse, comprenant la partie cylindrique de guidage.  Advantageously, the cradle comprises a cross member obtained by spinning, receiving on each side an elastomer block placed on the top forming the bearing of the anti-roll bar, and a front support obtained by spinning and fixed to this crosspiece, comprising the cylindrical part. guidance.
Avantageusement, la bride comporte une face supérieure venant au- dessus du bloc en élastomère, et une face arrière sensiblement verticale disposée à l'arrière de ce bloc.  Advantageously, the flange comprises an upper face coming above the elastomer block, and a substantially vertical rear face disposed at the rear of this block.
Avantageusement, la face supérieure de la bride se prolonge vers l'avant par la patte d'indexage.  Advantageously, the upper face of the flange is extended forward by the indexing tab.
En particulier, chaque côté de la bride peut comporter un rebord qui vient sur le côté du bloc en élastomère.  In particular, each side of the flange may have a flange that comes to the side of the elastomeric block.
Avantageusement, le moyen de serrage sur le berceau comporte une vis de serrage traversant la bride et le berceau.  Advantageously, the clamping means on the cradle comprises a clamping screw passing through the flange and the cradle.
L'invention a aussi pour objet un véhicule automobile comprenant un train roulant disposant d'une barre anti-devers maintenue par des systèmes de palier comportant l'une quelconque des caractéristiques précédentes.  The invention also relates to a motor vehicle comprising a running gear having an anti-roll bar maintained by bearing systems having any of the preceding characteristics.
L'invention sera mieux comprise et d'autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après, donnée à titre d'exemple en référence aux dessins annexés dans lesquels :  The invention will be better understood and other features and advantages will appear more clearly on reading the description below, given by way of example with reference to the accompanying drawings in which:
- la figure 1 est une vue en perspective d'un berceau avant de véhicule automobile, comportant un système de palier selon l'invention avant l'assemblage de la vis de serrage de la bride ;  - Figure 1 is a perspective view of a front cradle of a motor vehicle, comprising a bearing system according to the invention before assembly of the clamping screw of the flange;
- la figure 2 est une vue de côté de ce berceau avant ;  - Figure 2 is a side view of the front cradle;
- la figure 3 est une vue de détail du système de palier après la mise en place de la vis de serrage ; - les figures 4 à 6 sont des vues en coupe transversale du système de palier, respectivement au début, au milieu et en fin de serrage de la bride ; et- Figure 3 is a detailed view of the bearing system after the introduction of the clamping screw; - Figures 4 to 6 are cross-sectional views of the bearing system, respectively at the beginning, in the middle and at the end of clamping the flange; and
- la figure 7 est une vue du système de palier selon une variante. - Figure 7 is a view of the bearing system according to a variant.
La figure 1 présente un berceau avant 2 d'un véhicule automobile, comprenant une traverse 4 réalisée dans un profilé en alliage léger extrudé, comme un alliage d'aluminium ou de magnésium, qui est disposée transversalement dans le véhicule. Une flèche notée « AR » indique le côté arrière du véhicule.  Figure 1 shows a front cradle 2 of a motor vehicle, comprising a cross member 4 made of an extruded light alloy profile, such as an aluminum alloy or magnesium, which is arranged transversely in the vehicle. An arrow marked "AR" indicates the rear side of the vehicle.
De chaque côté du berceau avant 2, un support 6 est soudé sur une face avant de la traverse 4. Les supports 6 réalisés aussi dans un profilé extrudé suivant la même direction, forment des colonnes s'élevant nettement au-dessus de la traverse 4 qui est sensiblement plate.  On each side of the front cradle 2, a support 6 is welded to a front face of the crossbar 4. The supports 6 also made in an extruded section in the same direction, form columns rising significantly above the crossbar 4 which is substantially flat.
Chaque côté du berceau avant 2 est fixé en dessous de la carrosserie du véhicule, par une liaison arrière 8 se trouvant à l'arrière de la traverse 4, et une liaison avant 10 se trouvant au-dessus du support 6, ces liaisons comprenant des éléments élastiques pour éviter la transmission de vibrations à la caisse de ce véhicule.  Each side of the front cradle 2 is fixed below the body of the vehicle, by a rear link 8 located at the rear of the crossbar 4, and a front link 10 located above the support 6, these links comprising elastic elements to prevent the transmission of vibrations to the body of this vehicle.
On notera que le procédé d'extrusion d'un profilé d'alliage léger, à partir de cet alliage chauffé et comprimé pour passer dans une filière, permet de réaliser de manière économique un profilé disposant d'une section complexe, comprenant une bonne homogénéité de la matière, ainsi que des dimensions précises et un très bon état de surface permettant généralement d'utiliser ces surfaces directement sans les usiner.  It will be noted that the extrusion process of a light alloy profile, from this heated and compressed alloy to pass through a die, makes it possible to economically produce a section having a complex section, comprising a good homogeneity of the material, as well as precise dimensions and a very good surface condition generally allowing these surfaces to be used directly without machining them.
Pour réaliser le berceau 2, les profilés sont découpés et les extrémités sont usinées, puis les perçages sont réalisés, et enfin les supports 6 sont soudés sur la traverse 4.  To make the cradle 2, the profiles are cut and the ends are machined, then the holes are made, and finally the supports 6 are welded to the crossbar 4.
Une barre anti-devers 20 comporte une partie transversale sensiblement droite, fixée à chaque extrémité par un palier 22 disposé juste en arrière d'un support 6. Chaque côté de la barre anti-devers 20 comporte une partie coudée dont l'extrémité 24 est fixée sur un élément de la suspension, qui n'est pas représenté. De cette manière les mouvements différentiels de suspension importants entre les deux côtés du véhicule, communiqués aux extrémités 24 de la barre anti-devers 20, entraînent une torsion de la partie centrale de cette barre avec des forces en réaction qui peuvent être très élevées sur les paliers la supportant. An anti-roll bar 20 comprises a substantially straight transverse part, fixed at each end by a bearing 22 placed just behind a support 6. Each side of the anti-roll bar 20 has a bent part whose end 24 is attached to an element of the suspension, which is not shown. In this way the significant differential suspension movements between the two sides of the vehicle, communicated at the ends 24 of the anti-roll bar 20, cause the central part of this bar to twisting with reaction forces which can be very high on the bearings supporting it.
Les figures 2 et 3 présentent le système de palier 22 qui est symétrique par rapport à un plan perpendiculaire à l'axe de rotation de la barre anti- devers 20.  Figures 2 and 3 show the bearing system 22 which is symmetrical with respect to a plane perpendicular to the axis of rotation of the anti-roll bar 20.
Le système de palier 22 comporte un bloc en élastomère 32 comme un caoutchouc, traversé par la partie transversale de la barre anti-devers 20, comprenant une face avant en appui sur la surface arrière du support 6, et une face inférieure en appui sur le dessus de la traverse 4.  The bearing system 22 comprises an elastomer block 32 like a rubber, traversed by the transverse portion of the anti-roll bar 20, comprising a front face bearing on the rear surface of the support 6, and a lower face resting on the above the crossbar 4.
Une bride 30 allongée suivant l'axe longitudinal du véhicule, comporte une face supérieure venant au-dessus du bloc en élastomère 32, et une face arrière sensiblement verticale disposée à l'arrière de ce bloc, afin de le caler dans le plan longitudinal du véhicule. Chaque côté de la bride 30 comporte un rebord qui vient sur le côté du bloc en élastomère 32, afin de le caler latéralement.  An elongate flange 30 along the longitudinal axis of the vehicle comprises an upper face coming above the elastomer block 32, and a substantially vertical rear face disposed at the rear of this block, in order to wedge it in the longitudinal plane of the vehicle. Each side of the flange 30 has a flange that comes to the side of the elastomeric block 32 to wedge it laterally.
La face supérieure de la bride 30 se prolonge vers l'avant par une patte 34 comprenant une courbure disposant de génératrices parallèles à l'axe de rotation de la barre anti-devers 20, qui remonte vers le haut. La patte 34 est insérée dans une fente horizontale usinée dans la face arrière du support 6, juste en dessous d'un contour arrondi 36 de cette face se trouvant à l'intérieur du profilé, qui est obtenu directement par le procédé d'extrusion.  The upper face of the flange 30 is extended forward by a tab 34 comprising a curvature having generatrices parallel to the axis of rotation of the anti-roll bar 20, which rises upwards. The tab 34 is inserted into a horizontal slot machined in the rear face of the support 6, just below a rounded contour 36 of this face located inside the profile, which is obtained directly by the extrusion process.
En ajustant la courbure de la patte 34 sur le contour arrondi 36 du support 6, on obtient un indexage de la bride 30 par un point de fixation de sa partie avant calée vers le haut, qui forme un pivot permettant à cette bride de garder une grande surface de contact entre sa patte et le support pour des angles d'inclinaison variés de la bride.  By adjusting the curvature of the tab 34 on the rounded contour 36 of the support 6, an indexing of the flange 30 is obtained by a point of attachment of its upwardly wedged upward portion, which forms a pivot allowing this flange to maintain large contact area between its leg and the support for varying angles of inclination of the flange.
On notera que le contour arrondi 36 obtenu directement par filage de l'alliage léger, peut comporter une grande précision car ce procédé donne une géométrie précise ainsi que des états de surface très bons. La pression de contact entre la patte courbée 34 et le contour arrondi 36 peut être faible, avec une bonne répartition des efforts sur toute la surface. It will be noted that the rounded contour 36 obtained directly by spinning the light alloy can have a high accuracy because this method gives precise geometry as well as very good surface conditions. The contact pressure between the curved tab 34 and the rounded contour 36 may be low, with a good distribution of forces over the entire surface.
La bride 30 comporte en arrière de sa face verticale, une partie arrière sensiblement horizontale 40 venant en appui sur le dessus de la traverse 4, qui comporte un perçage allongé suivant l'axe longitudinal de cette bride. Le perçage allongé se prolonge vers l'avant de la bride 30, jusqu'à la face verticale de cette bride.  The flange 30 comprises behind its vertical face, a substantially horizontal rear portion 40 bearing on the top of the crossbar 4, which has an elongated bore along the longitudinal axis of this flange. The elongated bore extends forwardly of the flange 30 to the vertical face of this flange.
La partie arrière 40 de la bride 30 est raccordée à la face verticale par deux ailes latérales de renfort 42, assurant une bonne rigidité à l'angle formé entre ces deux parties.  The rear portion 40 of the flange 30 is connected to the vertical face by two lateral reinforcing wings 42, providing good rigidity at the angle formed between these two parts.
Un moyen de serrage traversant la traverse 4 vient serrer la partie arrière 40 de la bride 30 sur le dessus de cette traverse, afin de comprimer le bloc en élastomère 32 pour le maintenir fermement sur le berceau avant 2.  Clamping means passing through the cross member 4 clamps the rear portion 40 of the flange 30 on the top of the cross member to compress the elastomeric block 32 to hold it firmly on the front cradle 2.
Le moyen de serrage comporte une vis 46 venant par en dessous dans un perçage de la traverse 4, qui est vissée dans un perçage axial taraudé d'un écrou supérieur 44. L'écrou 44 comprend une partie cylindrique insérée dans le perçage allongé de la partie arrière 40 de la bride 30, et un épaulement supérieur de section carrée. Une entretoise 48 comprenant un perçage axial traversé par la vis 46, est insérée dans un creux de cette traverse afin d'éviter son écrasement.  The clamping means comprises a screw 46 coming from below in a bore of the cross member 4, which is screwed into an axial bore tapped with an upper nut 44. The nut 44 comprises a cylindrical portion inserted into the elongated bore of the rear portion 40 of the flange 30, and an upper shoulder of square section. A spacer 48 comprising an axial bore traversed by the screw 46, is inserted into a recess of this crosspiece to prevent crushing.
Le bloc en élastomère 32 dispose d'une pointe supérieure 38 qui est emboîtée dans un perçage de la face supérieure de la bride 30, permettant une tenue en position de cette bride avant la mise en place de la vis 46 et de son écrou 44.  The elastomer block 32 has an upper tip 38 which is engaged in a bore in the upper face of the flange 30, allowing this flange to be held in position before the screw 46 and its nut 44 are put in place.
Le procédé de montage du système de palier 22 est le suivant.  The mounting method of the bearing system 22 is as follows.
La figure 4 présente le début du montage du système de palier 22, la patte avant 34 de la bride 30 étant insérée dans la fente correspondante du support 6, pour prendre appui en dessous du contour arrondi 36 de ce support. Le moyen serrage est mis en place en déposant la partie cylindrique de l'écrou 44 dans le perçage allongé de la bride 30, cette partie cylindrique venant à l'extrémité avant de ce perçage, à cause de l'inclinaison de la bride autour de son axe de pivotement formé par le contour arrondi 36. La face avant du carré supérieur est proche de la partie verticale de cette bride, ce qui empêche une rotation de l'écrou 44. Figure 4 shows the beginning of the mounting of the bearing system 22, the front lug 34 of the flange 30 being inserted into the corresponding slot of the support 6, to bear below the rounded contour 36 of the support. The clamping means is put in place by depositing the cylindrical portion of the nut 44 in the elongate bore of the flange 30, this cylindrical portion coming to the front end of this bore, because of the inclination of the flange around its pivot axis formed by the rounded contour 36. The front face of the upper square is close to the vertical portion of this flange, which prevents rotation of the nut 44.
La vis 46 insérée dans le perçage de la traverse 4 et de l'entretoise 48, est engagée dans le filet de l'écrou 44.  The screw 46 inserted in the bore of the crosspiece 4 and the spacer 48 is engaged in the thread of the nut 44.
En complément, l'écrou 44 peut comporter dans sa partie supérieure une empreinte interne hexagonale, qui permet d'introduire une clé mâle dans cette empreinte lors de la mise en place de l'écrou afin de le guider et d'éviter sa rotation quand il est trop haut, la face avant du carré supérieur n'étant pas encore bloquée en rotation par la partie verticale de la bride 30.  In addition, the nut 44 may comprise in its upper part a hexagonal internal cavity, which makes it possible to introduce a male key into this footprint during the installation of the nut to guide it and to avoid its rotation when it is too high, the front face of the upper square is not yet locked in rotation by the vertical part of the flange 30.
La figure 5 présente la vis 46 qui est en milieu de serrage, la partie arrière 40 de la bride 30 étant nettement descendue ce qui fait pivoter cette bride autour du contour arrondi 36 du support 6. Les côtés du carré supérieur de l'écrou 44 sont descendus de manière ajustée entre les ailes latérales de renfort 42, qui donnent un blocage de cet écrou en empêchant toute rotation.  FIG. 5 shows the screw 46 which is in a clamping medium, the rear part 40 of the flange 30 being clearly lowered, which makes this flange pivot about the rounded contour 36 of the support 6. The sides of the upper square of the nut 44 have fitly descended between the lateral reinforcing wings 42, which give a lock of this nut preventing any rotation.
On notera que lors du pivotement de la bride 30 autour du contour arrondi 36, l'écrou 44 se déplace dans le perçage allongé vers l'arrière.  It will be appreciated that as the flange 30 pivots about the rounded contour 36, the nut 44 moves in the elongate bore rearwardly.
La figure 6 présente la vis 46 en fin de serrage, la partie arrière 40 de la bride 30 étant fortement serrée sur la face supérieure de la traverse 4, cette bride ayant fini sa descente en pivotant autour du contour arrondi 36, avec un serrage important du bloc en élastomère 32 qui est bien maintenu dans toutes les directions sur le berceau avant 2.  FIG. 6 shows the screw 46 at the end of tightening, the rear part 40 of the flange 30 being tightly tightened on the upper face of the crosspiece 4, this flange having finished its descent by pivoting around the rounded contour 36, with a large tightening of the elastomeric block 32 which is well maintained in all directions on the front cradle 2.
L'écrou 44 a fini de se déplacer vers l'arrière dans le perçage allongé de la bride 30, et se trouve à la fin tout à fait à l'arrière de ce perçage.  The nut 44 has finished moving backwards in the elongated bore of the flange 30, and is at the very end of the back of this bore.
La figure 7 présente une variante du système de palier, le support 6 comprenant un bossage cylindrique transversal comprenant un perçage axial 50, venu directement de filage. Une partie de ce bossage cylindrique est découpée de manière à former une fenêtre comprenant de la matière de chaque côté, recevant la patte avant 34 de la bride 30. Figure 7 shows a variant of the bearing system, the support 6 comprising a transverse cylindrical boss comprising an axial bore 50, directly from spinning. Part of this cylindrical boss is cut to form a window comprising material on each side, receiving the front tab 34 of the flange 30.
Un axe 52 en acier est inséré dans le perçage 50 de manière ajustée, pour former une surface extérieure cylindrique en métal résistant, recevant l'appui de la patte avant 34 comprenant un cintrage qui s'ajuste sur cette surface.  A steel pin 52 is inserted into the bore 50 in a controlled manner to form a cylindrical outer surface of strong metal receiving the support of the front leg 34 including a bend which fits over this surface.
On obtient ainsi avec une découpe simple du support 6 pour réaliser la fenêtre, et avec l'axe 52 inséré dans le perçage 50, une surface d'indexage résistante comprenant un positionnement précis donné par ce perçage obtenu directement par le procédé de filage.  Thus, with a simple cut of the support 6 to make the window, and with the axis 52 inserted in the bore 50, a resistant indexing surface comprising a precise positioning given by this hole obtained directly by the spinning process.
D'une manière générale, on obtient un serrage efficace du système de palier 22, comprenant un indexage de la bride 30 portant sur une large surface du berceau 2 ce qui réduit la pression de contact, et évite des problèmes vibratoires et acoustiques générés par ce contact. De plus cette faible pression limite les risques d'usure au niveau du point de contact.  In general, an effective clamping of the bearing system 22 is obtained, comprising indexing of the flange 30 covering a large surface of the cradle 2, which reduces the contact pressure, and avoids the vibrational and acoustic problems generated by this contact. In addition this low pressure limits the risk of wear at the point of contact.
Cette solution est simple et économique avec un nombre réduit de pièces, la forme particulière du berceau 2 comprenant le contour arrondi 36 obtenu directement par le filage de la matière, n'ajoutant pas de coût supplémentaire.  This solution is simple and economical with a small number of parts, the particular shape of the cradle 2 comprising the rounded contour 36 obtained directly by the spinning of the material, adding no additional cost.
De plus la forme allongée du perçage sur l'extrémité arrière de la bride In addition the elongated shape of the bore on the rear end of the flange
30, facilite l'assemblage de la barre anti-devers 20 sur le berceau 2. Elle permet en particulier la mise en place du moyen de serrage de l'arrière de la bride 30, malgré une forte inclinaison de cette bride pour l'introduction de sa patte avant 34 dans la fenêtre du support 6, sous la forme cylindrique de guidage 36. 30, facilitates the assembly of the anti-roll bar 20 on the cradle 2. It allows in particular the establishment of the clamping means of the rear of the flange 30, despite a high inclination of this flange for the introduction its front lug 34 in the window of the support 6, in the cylindrical guiding form 36.
Le système de fixation selon l'invention est particulièrement compact. En particulier la bride 30 peut comporter une épaisseur faible, et la forme supérieure carrée de l'écrou 44 peut comporter une hauteur très réduite, qui laisse de la place au-dessus du berceau 2 afin de disposer des organes du groupe motopropulseur. Le berceau 2 obtenu par l'assemblage de profilés en alliage léger 4, 6, peut être particulièrement léger et résistant. De plus ce procédé modulaire d'assemblage de profilés standard peut permettre de nombreuses combinaisons, ce qui facilite la réalisation de véhicules en petites séries sans nécessité à chaque fois des investissements importants. The fastening system according to the invention is particularly compact. In particular the flange 30 may have a small thickness, and the square upper form of the nut 44 may have a very small height, which leaves room above the cradle 2 in order to dispose of the powertrain members. The cradle 2 obtained by assembling light alloy profiles 4, 6, can be particularly lightweight and resistant. In addition, this modular method of assembling standard profiles can allow many combinations, which facilitates the production of vehicles in small series without need each time significant investments.
