Description

Description Description
Titre de l'invention : Véhicule comprenant un moteur monté sur un berceau au moyen d’une biellette. Title of the invention: Vehicle comprising an engine mounted on a cradle by means of a link.
[0001] La présente invention concerne un véhicule comprenant un moteur monté sur un berceau au moyen d’une biellette. The present invention relates to a vehicle comprising an engine mounted on a cradle by means of a link.
[0002] Afin de bien comprendre le positionnement des différentes pièces impliquées dans un véhicule selon l’invention, la description est réalisée en faisant référence à un repère orthonormé direct XYZ dans lequel X est un axe longitudinal avant- arrière du véhicule orienté vers l’arrière, Y est un axe transversal orienté vers la droite du véhicule et Z est un axe vertical dirigé vers le haut. [0002] In order to fully understand the positioning of the different parts involved in a vehicle according to the invention, the description is made with reference to a direct orthonormal reference XYZ in which X is a front-rear longitudinal axis of the vehicle oriented towards the rear, Y is a transverse axis oriented towards the right of the vehicle and Z is a vertical axis oriented upwards.
[0003] Les groupes motopropulseurs (GMP) des véhicules automobiles sont en général découplés du véhicule lui-même, pour éviter les remontées de choc desdits groupes motopropulseurs comprenant un moteur et une boite de vitesses, vers le véhicule. Ce découplage empêche donc une transmission des mouvements du moteur vers le véhicule et permet également de filtrer les vibrations dudit GMP vers l’habitacle du véhicule, qui constituent deux manifestations assez désagréables pour les occupants du véhicule. [0003] The powertrains (GMP) of motor vehicles are generally decoupled from the vehicle itself, to prevent shock from said powertrains comprising an engine and a gearbox, towards the vehicle. This decoupling therefore prevents transmission of movements from the engine to the vehicle and also makes it possible to filter the vibrations of said GMP towards the passenger compartment of the vehicle, which constitute two rather unpleasant manifestations for the occupants of the vehicle.
[0004] Une solution pour assurer ce découplage consiste par exemple à poser le moteur sur un berceau par l’intermédiaire d’un ensemble-support avant et d’un ensemble-support arrière, qui sont fixés à la fois sur le GMP et sur le berceau. [0004] One solution to ensure this decoupling consists for example of placing the engine on a cradle via a front support assembly and a rear support assembly, which are fixed both on the GMP and on the cradle.
[0005] En se référant aux figures 1 , 2 et 3, à titre d’illustration, un ensemble-support arrière 1 , comprend un support arrière 2 sur berceau 3, monté fixe sur ledit berceau 3 et un support arrière 4 sur GMP 5 monté fixe sur le GMP 5, et une liaison élastique 6 solidarisant entre eux lesdits deux supports arrière 2, 4. La liaison élastique 6 se présente sous la forme d’une articulation 7 ou « plot », qui comprend une bague extérieure 8 en plastique, une entretoise centrale 9 en aluminium et des parties en caoutchouc élastomère adhérisées sur l’entretoise 9 centrale et sur la bague extérieure 8 en plastique. Ce plot 7 est destiné à être emmanché dans l’orifice cylindrique du support sur berceau. Sa hauteur correspond sensiblement à l’épaisseur dudit support. Une fois que le plot 7 a été assemblé dans le support sur berceau, la liaison est solidarisée au support sur GMP par un boulon qui traverse l’entretoise centrale 9. Referring to Figures 1, 2 and 3, by way of illustration, a rear support assembly 1 comprises a rear support 2 on cradle 3, fixedly mounted on said cradle 3 and a rear support 4 on GMP 5 mounted fixedly on the GMP 5, and an elastic connection 6 joining together said two rear supports 2, 4. The elastic connection 6 is in the form of a joint 7 or “stud”, which comprises an outer ring 8 made of plastic , a central aluminum spacer 9 and elastomeric rubber parts adhered to the central spacer 9 and to the plastic outer ring 8. This stud 7 is intended to be fitted into the cylindrical orifice of the support on the cradle. Its height corresponds substantially to the thickness of said support. Once plot 7 has been assembled in the support on the cradle, the connection is secured to the support on the GMP by a bolt which passes through the central spacer 9.
[0006] Plus précisément, le support 4 sur GMP 5 présente à son extrémité non fixée sur le GMP 5, une forme de chape 10 qui vient prendre entre ses deux flasques l’entretoise 9 de l’articulation [0006] More precisely, the support 4 on GMP 5 has at its end not fixed on the GMP 5, a form of yoke 10 which takes between its two flanges the spacer 9 of the articulation
[0007] Cet exemple de liaison du GMP 5 sur le berceau 3 est non limitatif. Dans d’autres cas, ou en complément de celui-ci, on peut trouver par exemple des suspensions latérales gauche ou droite dans lesquelles l’axe du plot 7 est vertical et non pas horizontal comme dans l’exemple illustré aux figures 1 , 2 et 3. Dans encore d’autres cas, l’axe du plot 7 peut se trouver dans une position intermédiaire entre la position verticale et la position horizontale. [0007] This example of connection of GMP 5 to cradle 3 is non-limiting. In other cases, or in addition to this, we can find for example left or right lateral suspensions in which the axis of the stud 7 is vertical and not horizontal as in the example illustrated in Figures 1, 2 and 3. In still other cases, the axis of the stud 7 may be in an intermediate position between the vertical position and the horizontal position.
[0008] Un élastomère emmanché dans le support arrière sur berceau ou biellette, doit pouvoir tenir toute la durée de vie du véhicule, car il serait trop complexe de gérer des changements de tampon en élastomère en après-vente. En effet, dans le cas d’un tampon en élastomère emmanché dans le support côté berceau, son remplacement imposerait de démonter le berceau et d’avoir l’outil spécifique de presse pour enlever et emmancher un nouveau tampon. La durée d’intervention estimée est supérieure à dix fois la durée actuelle de changement d’une biellette basse de suspension classique. Or, à cause des contraintes d’architecture et de la reprise de couple du moteur, une inclinaison et/ou un balancement du moteur se produit, et ne permet plus à l'élastomère de la biellette de couple de travailler correctement. [0008] An elastomer fitted into the rear support on a cradle or link must be able to last the entire lifespan of the vehicle, because it would be too complex to manage changes of the elastomer pad after-sales. Indeed, in the case of an elastomer pad fitted into the cradle side support, its replacement would require dismantling the cradle and having the specific press tool to remove and fit a new pad. The estimated intervention time is more than ten times the current time for changing a conventional lower suspension link. However, due to architectural constraints and the recovery of torque from the motor, tilting and/or swaying of the motor occurs, and no longer allows the elastomer of the torque rod to work correctly.
[0009] En effet, l’élastomère est soumis à des efforts et couples provenant du moteur, et qui lui sont transmis par l’entretoise centrale, notamment selon l’exemple illustré un couple selon l’axe vertical Z, qui a tendance à écraser la partie gauche de l’élastomère vers l’arrière et la partie droite vers l’avant, car le plot est monté sans jeu dans le support côté berceau sur son diamètre extérieur. Sans précaution particulière, une telle situation aura pour conséquence une usure prématurée de l’élastomère. [0009] Indeed, the elastomer is subjected to forces and torques coming from the motor, and which are transmitted to it by the central spacer, in particular according to the example illustrated a torque along the vertical axis Z, which tends to crush the left part of the elastomer towards the rear and the right part towards the front, because the stud is mounted without play in the support on the cradle side on its external diameter. Without special precautions, such a situation will result in premature wear of the elastomer.
[00010] Un véhicule selon l’invention possède un groupe motopropulseur monté sur un berceau par l’intermédiaire d’une biellette qui est conçue pour retarder, voire éliminer l’usure de l’élastomère. [00011] L’invention a pour objet un véhicule comprenant un groupe motopropulseur, un berceau et une biellette de reprise de couple par l’intermédiaire de laquelle le groupe motopropulseur est monté sur le berceau, ladite biellette comprenant une première extrémité montée autour d’un premier axe de rotation reliant deux parois du berceau. [00010] A vehicle according to the invention has a powertrain mounted on a cradle via a link which is designed to delay or even eliminate wear of the elastomer. [00011] The subject of the invention is a vehicle comprising a powertrain, a cradle and a torque recovery link via which the powertrain is mounted on the cradle, said link comprising a first end mounted around a first axis of rotation connecting two walls of the cradle.
[00012] Selon l’invention, une rotule est fixée au premier axe, la première extrémité de la biellette comprenant une bague rigide, entourée par un premier tampon élastique, ladite bague rigide étant montée autour de la rotule de sorte que dans le cas d’un pivotement de la biellette résultant d’un mouvement du groupe motopropulseur, la bague rigide se déplace autour de la rotule pour accompagner ce pivotement, en minimisant les efforts sur ledit premier tampon élastique. Le cœur de l’invention est constitué par la rotule dont la présence va empêcher le tampon élastique de travailler en rotation. En effet, le groupe motopropulseur étant fixé au véhicule en étant pendulé, il va donc se déplacer lors d’une phase de roulage du véhicule, engendrant un léger déplacement de la biellette par pivotement. Généralement, lors du pivotement de la biellette, le tampon élastique placé autour de la bague, va travailler à la fois en traction et en rotation. Grâce à la présence de la rotule, ledit tampon élastique ne va plus travailler qu’en traction puisque les efforts en rotation sur ledit tampon seront minimisés voire annulés, par la présence de la rotule. Il en résulte que le tampon élastique subira moins d’efforts durant la durée de vie du véhicule, et sera donc préservé plus longtemps, sans nécessité de le changer. Il est à préciser que la biellette est montée en rotation autour du premier axe de rotation, en s’étendant perpendiculairement audit premier axe, et que le pivotement de la biellette induit par le mouvement du groupe motopropulseur lors d’une phase de roulage du véhicule, s’effectue de telle manière que la biellette ne se retrouve plus rigoureusement perpendiculaire audit premier axe. La rotule a pour fonction de réduire, voire d’annuler les efforts en rotation exercés sur le tampon élastique afin de ralentir l’usure dudit tampon. La rotule a préférentiellement une forme sphérique et est solidarisée au premier axe de rotation. Avantageusement, le premier axe de rotation a une forme cylindrique. La biellette peut par exemple être placée dans le véhicule en s’étendant horizontalement suivant un axe longitudinal X de ce véhicule, ou bien être placée dans ledit véhicule en s’étendant verticalement. D’autres orientations intermédiaires sont encore possibles. Il est naturellement supposé que la rotule est fixée au premier axe de rotation, en étant placée entre les deux parois du berceau. [00012] According to the invention, a ball joint is fixed to the first axis, the first end of the link comprising a rigid ring, surrounded by a first elastic buffer, said rigid ring being mounted around the ball joint so that in the case of 'a pivoting of the link resulting from a movement of the powertrain, the rigid ring moves around the ball joint to accompany this pivoting, minimizing the forces on said first elastic buffer. The heart of the invention consists of the ball joint, the presence of which will prevent the elastic buffer from rotating. Indeed, the powertrain being fixed to the vehicle by being pendulumed, it will therefore move during a rolling phase of the vehicle, causing a slight movement of the link by pivoting. Generally, when the link pivots, the elastic buffer placed around the ring will work both in traction and in rotation. Thanks to the presence of the ball joint, said elastic pad will only work in traction since the rotational forces on said pad will be minimized or even canceled by the presence of the ball joint. As a result, the elastic buffer will undergo less stress during the life of the vehicle, and will therefore be preserved for longer, without the need to change it. It should be noted that the link is mounted to rotate around the first axis of rotation, extending perpendicular to said first axis, and that the pivoting of the link induced by the movement of the powertrain during a rolling phase of the vehicle , is carried out in such a way that the link no longer finds itself strictly perpendicular to said first axis. The function of the ball joint is to reduce or even eliminate the rotational forces exerted on the elastic pad in order to slow down the wear of said pad. The ball joint preferably has a spherical shape and is secured to the first axis of rotation. Advantageously, the first axis of rotation has a cylindrical shape. The link can for example be placed in the vehicle extending horizontally along a longitudinal axis X of this vehicle, or else be placed in said vehicle in extending vertically. Other intermediate directions are still possible. It is naturally assumed that the ball joint is fixed to the first axis of rotation, being placed between the two walls of the cradle.
[00013] Selon une caractéristique possible de l’invention, la bague rigide est au contact de la rotule. Pour ce mode de réalisation, aucun revêtement ni aucune couche intercalaire ne s’interpose entre la bague rigide et la rotule. Lors d’un pivotement de la biellette dû au déplacement du groupe motopropulseur pendant une phase de roulage du véhicule, la bague rigide va pivoter directement et simultanément sur la rotule. La bague rigide est assimilable à une couronne s’étendant suivant une première direction alignée sur un diamètre de la rotule, et qui peut se déplacer autour de la rotule pour s’étendre suivant une deuxième direction qui est alignée sur un diamètre de la sphère et qui est différente de la première direction. [00013] According to a possible characteristic of the invention, the rigid ring is in contact with the ball joint. For this embodiment, no coating or intermediate layer is interposed between the rigid ring and the ball joint. When the link pivots due to the movement of the powertrain during a vehicle rolling phase, the rigid ring will pivot directly and simultaneously on the ball joint. The rigid ring can be compared to a crown extending in a first direction aligned with a diameter of the ball joint, and which can move around the ball joint to extend in a second direction which is aligned with a diameter of the sphere and which is different from the first direction.
[00014] Selon une caractéristique possible de l’invention, la bague rigide présente une surface interne arrondie épousant la forme de la rotule, un pivotement de la biellette entraînant un pivotement simultané de la bague rigide autour de la rotule. Autrement dit, la surface interne de la bague rigide épouse étroitement la forme de la rotule, permettant à ladite bague rigide de pivoter en glissant sur la rotule. [00014] According to a possible characteristic of the invention, the rigid ring has a rounded internal surface matching the shape of the ball joint, a pivoting of the link causing simultaneous pivoting of the rigid ring around the ball joint. In other words, the internal surface of the rigid ring closely matches the shape of the ball joint, allowing said rigid ring to pivot while sliding on the ball joint.
[00015] Selon une caractéristique possible de l’invention, la bague rigide est indéformable pour les niveaux d’effort engendrés sur la première extrémité de la biellette lors d’un pivotement de celle-ci. La bague rigide accompagne le pivotement de la biellette sans se déformer, pour favoriser ce mouvement de pivotement. [00015] According to a possible characteristic of the invention, the rigid ring is non-deformable for the levels of force generated on the first end of the link during pivoting thereof. The rigid ring accompanies the pivoting of the link without deforming, to promote this pivoting movement.
[00016] Selon une caractéristique possible de l’invention, la rotule est de forme sphérique. Il s’agit d’un mode de réalisation préféré d’un véhicule selon l’invention. [00016] According to a possible characteristic of the invention, the ball joint is of spherical shape. This is a preferred embodiment of a vehicle according to the invention.
[00017] Selon une caractéristique possible de l’invention, la rotule est métallique. [00017] According to a possible characteristic of the invention, the ball joint is metallic.
[00018] Selon une caractéristique possible de l’invention, la rotule s’étend le long du premier axe de rotation de façon à venir tangenter les deux parois du berceau. [00019] Selon une caractéristique possible de l’invention, la biellette présente un corps comprenant la première extrémité et une deuxième extrémité montée autour d’un deuxième axe de rotation reliant deux parois du groupe motopropulseur, ladite deuxième extrémité étant traversée par un trou prévu pour le passage du deuxième axe et dans lequel a été placé un deuxième tampon élastique destiné à entourer le deuxième axe de rotation. Le corps de la biellette est allongé, la première extrémité et la deuxième extrémité de la biellette étant à considérer le long d’un axe longitudinal de la biellette. Lorsque le groupe motopropulseur se déplace lors d’une phase de roulage du véhicule, les deux parois dudit groupe motopropulseur se déplacent également et impriment à la biellette un mouvement de pivotement permettant à la bague rigide de la première extrémité de se déplacer sur et autour de la rotule. La présence du deuxième tampon élastique permet d’amortir les efforts engendrés entre le deuxième axe de rotation reliant les deux parois du groupe motopropulseur, et la deuxième extrémité de la biellette lorsque ladite biellette pivote. [00018] According to a possible characteristic of the invention, the ball joint extends along the first axis of rotation so as to tangent to the two walls of the cradle. [00019] According to a possible characteristic of the invention, the link has a body comprising the first end and a second end mounted around a second axis of rotation connecting two walls of the powertrain, said second end being crossed by a hole provided for the passage of the second axis and in which a second elastic buffer intended to surround the second axis of rotation has been placed. The body of the link is elongated, the first end and the second end of the link being considered along a longitudinal axis of the link. When the power unit moves during a rolling phase of the vehicle, the two walls of said power unit also move and give the link a pivoting movement allowing the rigid ring of the first end to move on and around the kneecap. The presence of the second elastic buffer makes it possible to absorb the forces generated between the second axis of rotation connecting the two walls of the powertrain, and the second end of the link when said link pivots.
[00020] Selon une caractéristique possible de l’invention, le corps de la biellette est en aluminium. De cette manière la biellette possède une bonne tenue mécanique tout en demeurant légère. [00020] According to a possible characteristic of the invention, the body of the link is made of aluminum. In this way the link has good mechanical strength while remaining light.
[00021] Selon une caractéristique possible de l’invention, le corps de la biellette s’étend horizontalement le long d’un axe longitudinal X du véhicule, de sorte que la deuxième extrémité soit placée devant la première extrémité. Ce positionnement de la biellette est effectif lorsque le groupe motopropulseur ne fonctionne pas et qu’il n’entraine donc pas un pivotement de ladite biellette. [00021] According to a possible characteristic of the invention, the body of the link extends horizontally along a longitudinal axis X of the vehicle, so that the second end is placed in front of the first end. This positioning of the link is effective when the powertrain is not operating and therefore does not cause said link to pivot.
[00022] On donne ci-après, une description détaillée d’un mode de réalisation préféré d’un véhicule selon l’invention en se référant aux figures suivantes : [00022] Below is a detailed description of a preferred embodiment of a vehicle according to the invention with reference to the following figures:
[00023] [Fig. 1] La figure 1 est une vue en perspective d’un berceau, d’un moteur et d’un ensemble support dudit moteur sur ledit berceau d’un véhicule selon l’état de la technique, [00023] [Fig. 1] Figure 1 is a perspective view of a cradle, an engine and a support assembly for said engine on said cradle of a vehicle according to the state of the art,
[00024] [Fig. 2] La figure 2 est une vue agrandie d’une zone de l’ensemble support de la figue 1 , [00024] [Fig. 2] Figure 2 is an enlarged view of an area of the support assembly of Fig 1,
[00025] [Fig. 3] La figure 3 est une vue en perspective en éclaté de la zone de la figure 3, [00026] [Fig. 4] La figure 4 est une vue schématique d’un berceau, d’un groupe motopropulseur et d’une biellette de liaison entre ledit berceau et ledit moteur d’un véhicule selon l’invention, ladite biellette étant dans une première position,[00025] [Fig. 3] Figure 3 is an exploded perspective view of the area of Figure 3, [00026] [Fig. 4] Figure 4 is a schematic view of a cradle, a powertrain and a connecting link between said cradle and said engine of a vehicle according to the invention, said link being in a first position,
[00027] [Fig. 5] La figure 5 est une vue schématique d’un berceau, d’un groupe motopropulseur et d’une biellette de liaison entre ledit berceau et ledit moteur d’un véhicule selon l’invention, ladite biellette étant dans une deuxième position. [00027] [Fig. 5] Figure 5 is a schematic view of a cradle, a powertrain and a connecting link between said cradle and said engine of a vehicle according to the invention, said link being in a second position.
[00028] Les figures 1 , 2 et 3 ont été décrites précédemment. [00028] Figures 1, 2 and 3 have been described previously.
[00029] En se référant aux figures 4 et 5, un véhicule selon l’invention comprend un groupe motopropulseur 105, un berceau 103 et une biellette 110, ledit groupe motopropulseur 105 étant monté sur le berceau 103 par l’intermédiaire de ladite biellette 110. En effet, le groupe motopropulseur 105 étant susceptible de se déplacer et d’engendrer des vibrations lors d’une phase de roulage du véhicule, il est monté dans ledit véhicule en étant découplé de celui-ci, afin d’empêcher que ledit déplacement et lesdites vibrations ne soient transmis jusqu’à l’habitacle du véhicule. La biellette 110 a notamment pour objectif d’assurer le découplage entre le groupe motopropulseur 105 et le véhicule. Referring to Figures 4 and 5, a vehicle according to the invention comprises a powertrain 105, a cradle 103 and a link 110, said powertrain 105 being mounted on the cradle 103 via said link 110 Indeed, the powertrain 105 being capable of moving and generating vibrations during a rolling phase of the vehicle, it is mounted in said vehicle while being decoupled from it, in order to prevent said movement and said vibrations are not transmitted to the passenger compartment of the vehicle. The purpose of the link 110 is in particular to ensure decoupling between the powertrain 105 and the vehicle.
[00030] En se référant aux figures 4 et 5, la biellette 110 comprend un corps[00030] Referring to Figures 4 and 5, the link 110 comprises a body
111 allongé dont une première extrémité 112 est montée pivotante autour d’un premier axe 113 du berceau 103, et dont une deuxième extrémité 114 est montée pivotante autour d’un deuxième axe 115 du groupe motopropulseur 105. Le corps 111 est avantageusement réalisé en aluminium. La première extrémité111 elongated, a first end 112 of which is pivotally mounted around a first axis 113 of the cradle 103, and a second end 114 of which is pivotally mounted around a second axis 115 of the powertrain 105. The body 111 is advantageously made of aluminum . The first end
112 et la deuxième extrémité 114 de la biellette 110 sont à considérer par rapport à un axe longitudinal de celle-ci. Le berceau 103 comporte deux parois 116, 117 parallèles, qui sont reliées l’une à l’autre par une première vis 118 s’étendant perpendiculairement auxdites parois 116, 117. Un insert cylindrique 119 entoure ladite première vis 118 en venant en butée contre lesdites deux parois 116, 117, ledit insert cylindrique 119 constituant le premier axe 113. Cet insert cylindrique112 and the second end 114 of the link 110 are to be considered in relation to a longitudinal axis thereof. The cradle 103 comprises two parallel walls 116, 117, which are connected to each other by a first screw 118 extending perpendicular to said walls 116, 117. A cylindrical insert 119 surrounds said first screw 118, abutting against said two walls 116, 117, said cylindrical insert 119 constituting the first axis 113. This cylindrical insert
119 joue le rôle d’une entretoise entre les deux parois 116, 117 du berceau 103. Le groupe motopropulseur 105 comporte deux parois 120, 121 parallèles, qui sont reliées l’une à l’autre par une deuxième vis 122 s’étendant perpendiculairement auxdites parois 120, 121. Un insert cylindrique 123 entoure ladite deuxième vis 122 en venant en butée contre lesdites deux parois 120, 121 , ledit insert cylindrique 123 constituant le deuxième axe 115. Cet insert cylindrique 119 joue le rôle d’une entretoise entre les deux parois 120, 121 du groupe motopropulseur 105. 119 plays the role of a spacer between the two walls 116, 117 of the cradle 103. The powertrain 105 comprises two parallel walls 120, 121, which are connected to each other by a second screw 122 extending perpendicularly to said walls 120, 121. A cylindrical insert 123 surrounds said second screw 122 abutting against said two walls 120, 121, said cylindrical insert 123 constituting the second axis 115. This cylindrical insert 119 plays the role of a spacer between the two walls 120, 121 of the power unit 105.
[00031] La deuxième extrémité 114 de la biellette 110 possède un orifice traversant, s’étendant perpendiculairement à un axe longitudinal du corps 111 de ladite biellette 110. Un deuxième tampon élastique 124 ayant la forme d’un cylindre creux et réalisé en élastomère, est placé dans l’orifice traversant de la deuxième extrémité 114. La deuxième extrémité 114 de la biellette 110 est montée en rotation autour de l’insert cylindrique 123 placé autour de la vis 122 de sorte que le deuxième tampon élastique 124 vienne directement enserrer ledit insert 123. Le deuxième tampon élastique 124 s’étend sur toute la longueur de l’orifice traversant, c’est-à-dire sur toute la largeur de la deuxième extrémité 114 de la biellette 110, sans déborder de ladite biellette 110. [00031] The second end 114 of the link 110 has a through orifice, extending perpendicular to a longitudinal axis of the body 111 of said link 110. A second elastic buffer 124 having the shape of a hollow cylinder and made of elastomer, is placed in the through hole of the second end 114. The second end 114 of the link 110 is mounted to rotate around the cylindrical insert 123 placed around the screw 122 so that the second elastic buffer 124 comes directly to grip said insert 123. The second elastic buffer 124 extends over the entire length of the through hole, that is to say over the entire width of the second end 114 of the link 110, without extending beyond said link 110.
[00032] L’insert cylindrique 119 placé autour de la vis 118 reliant les deux parois 116, 117 du berceau 103, porte une rotule 125 sphérique préférentiellement réalisée en métal et qui est placée entre les deux parois 116, 117 du berceau 103. Cette rotule 125 est fixée à l’insert cylindrique 119 sans possibilité de mouvement par rapport audit insert cylindrique 119. De façon préférentielle, la rotule 125 vient tangenter les deux parois 116, 117 du berceau 103. Autrement dit, dans ce cas, la rotule 125 s’étend sur toute la longueur de l’insert cylindrique 119. [00032] The cylindrical insert 119 placed around the screw 118 connecting the two walls 116, 117 of the cradle 103, carries a spherical ball joint 125 preferably made of metal and which is placed between the two walls 116, 117 of the cradle 103. This ball joint 125 is fixed to the cylindrical insert 119 without the possibility of movement relative to said cylindrical insert 119. Preferably, the ball joint 125 tangents the two walls 116, 117 of the cradle 103. In other words, in this case, the ball joint 125 extends over the entire length of the cylindrical insert 119.
[00033] La première extrémité 112 de la biellette 110 comprend une bague rigide 126 de forme cylindrique et possédant un canal interne cylindrique, dont le diamètre est légèrement supérieur à celui de la rotule 125. Cette bague rigide 126 est entourée par un premier tampon élastique 127, préférentiellement réalisé en élastomère, ledit premier tampon élastique 127 étant de forme cylindrique. La bague rigide 126 et le tampon élastique 127 sont disposés l’un par rapport à l’autre de façon concentrique, c’est-à-dire qu’ils sont disposés de manière que leurs axes de révolution soient confondus, la bague rigide 126 étant placée à l’intérieur du tampon élastique 127. L’ensemble constitué par la bague rigide 126 et le tampon élastique 127 est placé dans un trou traversant de la première extrémité 112 de la biellette 110, ledit trou étant de forme cylindrique et ayant un diamètre sensiblement égal au diamètre extérieur du tampon élastique 127. Cet ensemble est avantageusement rentré à force dans le trou traversant de la première extrémité 112 de la biellette 110. The first end 112 of the link 110 comprises a rigid ring 126 of cylindrical shape and having a cylindrical internal channel, the diameter of which is slightly greater than that of the ball joint 125. This rigid ring 126 is surrounded by a first elastic buffer 127, preferably made of elastomer, said first elastic pad 127 being of cylindrical shape. The rigid ring 126 and the elastic buffer 127 are arranged relative to each other in a concentric manner, that is to say they are arranged so that their axes of revolution coincide, the rigid ring 126 being placed inside the elastic pad 127. The assembly consisting of the rigid ring 126 and the elastic pad 127 is placed in a through hole of the first end 112 of the link 110, said hole being of cylindrical shape and having a diameter substantially equal to the external diameter of the elastic buffer 127. This assembly is advantageously forced into the through hole of the first end 112 of the link 110.
[00034] La première extrémité 112 de la biellette 110 est montée autour de la rotule 125 de sorte que la bague rigide 126 vienne se placer autour et au contact de la rotule 125. [00034] The first end 112 of the link 110 is mounted around the ball joint 125 so that the rigid ring 126 is placed around and in contact with the ball joint 125.
[00035] Dans l’exemple illustré aux figures 4 et 5, la biellette 110 s’étend horizontalement suivant un axe longitudinal X du véhicule. Il est à noter que selon une variante de réalisation de l’invention, la biellette 110 pourrait s’étendre verticalement. [00035] In the example illustrated in Figures 4 and 5, the link 110 extends horizontally along a longitudinal axis X of the vehicle. It should be noted that according to a variant embodiment of the invention, the link 110 could extend vertically.
[00036] En se référant à la figure 4, lorsque le groupe motopropulseur 105 ne fonctionne pas, la biellette 115 s’étend horizontalement suivant un axe longitudinal X et horizontal du véhicule. Elle s’étend perpendiculairement à la première vis 118 reliant les deux parois 116, 117 du berceau 103, et à la deuxième vis 122 reliant les deux parois 120, 121 du groupe motopropulseur 105. [00036] Referring to Figure 4, when the powertrain 105 is not operating, the link 115 extends horizontally along a longitudinal and horizontal axis X of the vehicle. It extends perpendicularly to the first screw 118 connecting the two walls 116, 117 of the cradle 103, and to the second screw 122 connecting the two walls 120, 121 of the powertrain 105.
[00037] En se référant à la figure 5, lorsque le groupe motopropulseur 105 fonctionne, lors par exemple d’une phase de roulage du véhicule, il s’élève légèrement par rapport à sa position pour laquelle le groupe motopropulseur 105 ne fonctionne pas, entraînant un léger pivotement de la biellette 110 dans un plan vertical et longitudinal XZ du véhicule. La biellette 110 ne s’étend plus perpendiculairement à la première vis 118. La rotule 125 favorise le pivotement de la biellette 110 par l’intermédiaire du pivotement de la bague rigide 126 sur et autour de la rotule 125, en réduisant voire en annulant les efforts en rotation sur le premier tampon élastique 127 qui n’est plus sollicité qu’en traction. Il en résulte que grâce à la présence de la rotule 125, le premier tampon élastique 127 de la première extrémité 112 de la biellette 110 est moins sollicité, et sera donc préservé plus longtemps. Il ne sera donc pas nécessaire de changer souvent le premier tampon élastique 127 de la biellette 110, durant la durée de vie du véhicule. [00037] Referring to Figure 5, when the powertrain 105 is operating, for example during a driving phase of the vehicle, it rises slightly relative to its position for which the powertrain 105 is not operating, causing a slight pivoting of the link 110 in a vertical and longitudinal plane XZ of the vehicle. The link 110 no longer extends perpendicular to the first screw 118. The ball joint 125 promotes the pivoting of the link 110 via the pivoting of the rigid ring 126 on and around the ball joint 125, by reducing or even canceling the rotational forces on the first elastic pad 127 which is only stressed in traction. The result is that thanks to the presence of the ball joint 125, the first elastic buffer 127 of the first end 112 of the link 110 is less stressed, and will therefore be preserved for longer. It will therefore not be necessary to often change the first elastic buffer 127 of the link 110, during the life of the vehicle.
