Description
La présente invention concerne un véhicule automobile équipé de ressorts de suspension maintenus par une coupelle supérieure, ainsi qu’un procédé d’assemblage d’un ressort de suspension sur un tel véhicule.The present invention relates to a motor vehicle equipped with suspension springs held by an upper cup, as well as a method of assembling a suspension spring on such a vehicle.
Un type de train arrière connu, présenté notamment par le document FR-A1-2989611, comporte de chaque côté du véhicule un bras de suspension présentant à l’avant un axe transversal de pivotement, qui reçoit vers l’arrière une roue, et une plaque d’appui inférieure de ressort de suspension disposée sensiblement horizontalement. Le ressort est maintenu et guidé par la plaque d'appui inférieure et la coupelle supérieure, qui le compriment lors des mouvements de la suspension.A known type of rear axle, presented in particular by the document FR-A1-2989611, comprises on each side of the vehicle a suspension arm having at the front a transverse pivot axis, which receives a wheel towards the rear, and a suspension spring lower support plate arranged substantially horizontally. The spring is held and guided by the lower support plate and the upper cup, which compress it during suspension movements.
Dans certains cas la coupelle supérieure dispose d’une semelle d’appui plate réalisée en matière plastique ou en élastomère, formant une interface entre le ressort et cette coupelle afin d’éviter des bruits qui seraient générés par un contact direct du ressort sur la tôle de la caisse du véhicule.In some cases the upper cup has a flat bearing plate made of plastic or elastomer, forming an interface between the spring and this cup in order to avoid noise which would be generated by direct contact of the spring on the sheet. of the vehicle body.
Ce document présente un procédé de montage du ressort de suspension, utilisant un outil de compression comportant deux parties coulissantes, disposant chacune d’un bec engagé entre des spires d’extrémités du ressort. Une manœuvre de l’outil permet un rapprochement des deux becs, et une compression du ressort qui présente ainsi une longueur suffisamment réduite pour pouvoir être inséré entre les deux coupelles.This document presents a method for mounting the suspension spring, using a compression tool comprising two sliding parts, each having a beak engaged between the end turns of the spring. A maneuver of the tool allows a bringing together of the two beaks, and a compression of the spring which thus has a sufficiently short length to be able to be inserted between the two cups.
En particulier la coupelle supérieure présente un moyeu de centrage qui s’ajuste dans le centre des spires supérieures, pour réaliser un guidage de l’extrémité supérieure du ressort. On relève ensuite le bras de suspension qui continue la compression du ressort, pour l’ajuster à un niveau permettant la mise en place d’un amortisseur télescopique limitant le débattement maximum de ce bras.In particular, the upper cup has a centering hub which fits in the center of the upper coils, to guide the upper end of the spring. The suspension arm is then raised, which continues the compression of the spring, to adjust it to a level allowing the installation of a telescopic shock absorber limiting the maximum travel of this arm.
Toutefois ce type de procédé d’assemblage nécessite un outillage complexe, lourd et délicat à manœuvrer, qui peut présenter certains dangers en cas de mauvais positionnement à cause de l’énergie emmagasinée dans le ressort. De plus pour certains types de ressort assez longs, l’espace entre les spires d’extrémités comprimées est réduit ce qui fait que les becs peuvent se trouver bloqués par ces spires en fin de compression.However, this type of assembly process requires complex, heavy and delicate tools to operate, which can present certain dangers in the event of poor positioning due to the energy stored in the spring. In addition, for certain types of fairly long springs, the space between the compressed end turns is reduced, which means that the slats can be blocked by these turns at the end of compression.
La présente invention a notamment pour but d’éviter ces problèmes de l’art antérieur.The object of the present invention is in particular to avoid these problems of the prior art.
Elle propose à cet effet un véhicule automobile comportant un ressort de suspension, une plaque d’appui inférieure fixée à un bras de suspension pivotant, et une coupelle supérieure fixée à la caisse du véhicule, qui comprend une semelle d’appui de l’extrémité supérieure du ressort et un moyeu de centrage rentrant dans des spires supérieures du ressort, ce véhicule étant remarquable en ce que lorsque la plaque d’appui inférieur et la coupelle sont écartées au maximum avant le montage d’un amortisseur télescopique limitant le débattement du bras de suspension, le ressort étant posé sur la plaque d’appui inférieure, le moyeu de centrage comporte une longueur permettant à son extrémité de rester engagée dans les spires supérieures du ressort en assurant son guidage.It proposes for this purpose a motor vehicle comprising a suspension spring, a lower support plate fixed to a pivoting suspension arm, and an upper cup fixed to the body of the vehicle, which comprises a support plate for the end upper part of the spring and a centering hub fitting into upper coils of the spring, this vehicle being remarkable in that when the lower support plate and the cup are spaced apart as far as possible before mounting a telescopic shock absorber limiting the movement of the arm suspension, the spring being placed on the lower support plate, the centering hub has a length allowing its end to remain engaged in the upper coils of the spring ensuring its guidance.
Un avantage de ce véhicule est qu'on peut sans outillage de compression du ressort, de manière simple et rapide engager son extrémité supérieure autour du moyeu de centrage, puis poser son extrémité inférieure sur la plaque d’appui avec le bras de suspension complètement abaissé, qui n'est pas retenu par l'amortisseur. La longueur de guidage du moyeu de la coupelle est alors suffisante pour garder l’extrémité supérieure du ressort engagée autour de ce moyeu, en empêchant le basculement du ressort.An advantage of this vehicle is that you can simply and quickly engage its upper end around the centering hub without tools for compressing the spring, then rest its lower end on the support plate with the suspension arm completely lowered. , which is not retained by the damper. The guide length of the cup hub is then sufficient to keep the upper end of the spring engaged around this hub, preventing the spring from tilting.
On peut ensuite simplement relever le bras de suspension par un pivotement autour de son axe pour comprimer le ressort de manière sécurisée, sans outillage spécifique, jusqu’à la position permettant la fixation de l’amortisseur qui maintient une compression minimum de ce ressort.You can then simply raise the suspension arm by pivoting around its axis to compress the spring in a secure manner, without specific tools, to the position allowing the attachment of the shock absorber which maintains a minimum compression of this spring.
Le véhicule automobile selon l’invention peut comporter une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The motor vehicle according to the invention may comprise one or more of the following characteristics, which may be combined with one another.
Avantageusement, le moyeu de centrage présente une forme extérieure conique qui se resserre vers le bas.Advantageously, the centering hub has a conical outer shape which tapers downwards.
En particulier, le moyeu de centrage peut comporter une partie cylindrique recevant autour des ailettes orientées axialement formant un contour extérieur réalisant le guidage du ressort.In particular, the centering hub may comprise a cylindrical part receiving around fins oriented axially forming an outer contour performing the guiding of the spring.
Avantageusement, la coupelle est fixée sous la caisse du véhicule par un dispositif de clipsage.Advantageously, the cup is fixed under the body of the vehicle by a clipping device.
Selon un mode de réalisation, le dispositif de clipsage comporte des clips élastiques ajustés dans un perçage d’une tôle de la caisse du véhicule, qui viennent se clipser au-dessus de cette tôle.According to one embodiment, the clipping device comprises elastic clips fitted in a hole in a sheet of the vehicle body, which are clipped above this sheet.
Selon un autre mode de réalisation, le dispositif de clipsage comporte un téton central disposant sur les côtés de bossages élastiques qui se compriment en passant dans un perçage d’une tôle de la caisse du véhicule, pour se détendre au-dessus de cette tôle.According to another embodiment, the clipping device comprises a central stud having elastic bosses on the sides which are compressed by passing through a hole in a sheet of the vehicle body, in order to relax above this sheet.
Avantageusement, la coupelle est formée d’une seule pièce par un moulage d’une matière plastique ou d’un élastomère.Advantageously, the cup is formed in one piece by molding a plastic material or an elastomer.
En particulier, le bras de suspension peut être monté sur un train arrière du véhicule.In particular, the suspension arm can be mounted on a rear axle of the vehicle.
L’invention a aussi pour objet un procédé d’assemblage d’un véhicule automobile comprenant l’une quelconque des caractéristiques précédentes, remarquable en ce qu’il comporte une étape d’inclinaison du ressort de suspension et d’ajustement des spires supérieures autour du moyeu de centrage, puis une étape de pose de son extrémité inférieure sur la plaque d’appui inférieur.The invention also relates to a method for assembling a motor vehicle comprising any one of the preceding characteristics, noteworthy in that it comprises a step of inclining the suspension spring and adjusting the upper coils around of the centering hub, then a step of laying its lower end on the lower bearing plate.
Avantageusement, le procédé comporte une étape suivante de remontée du bras de suspension entraînant une compression du ressort de suspension, puis de fixation de l’amortisseur télescopique sur ce bras de suspension.Advantageously, the method comprises a following step of raising the suspension arm causing compression of the suspension spring, then fixing the telescopic shock absorber on this suspension arm.
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 characteristics and advantages will appear more clearly on reading the description below given by way of example, with reference to the appended drawings in which:
Dans l’ensemble du document les expressions au-dessus, en dessous, supérieur, inférieur, sont relatives à un véhicule posé sur un sol horizontal. La direction avant du véhicule est indiquée par la flèche AV.Throughout the document, the expressions above, below, upper, lower, relate to a vehicle resting on horizontal ground. The forward direction of the vehicle is indicated by the forward arrow.
Les figures 1 et 2 présentent une structure de véhicule fixée sous la caisse à l’arrière, formée par une tôle comprenant une partie sensiblement verticale 2 soudée sur un côté de cette caisse, et une partie sensiblement horizontale centrée autour d’un axe principal A, comportant un contour extérieur 4 et une face d’appui circulaire 6 disposée un peu plus bas, présentant au centre un cône de centrage 8 descendant sous cette face d’appui.Figures 1 and 2 show a vehicle structure fixed under the body at the rear, formed by a sheet comprising a substantially vertical part 2 welded to one side of this body, and a substantially horizontal part centered around a main axis A , comprising an outer contour 4 and a circular support face 6 arranged a little lower, having in the center a centering cone 8 descending under this support face.
La base du cône de centrage 8 forme une surface plate transversale présentant un perçage central 18.The base of the centering cone 8 forms a transverse flat surface having a central bore 18.
Une coupelle 10 réalisée par un moulage d’une matière plastique ou d’un élastomère, forme une pièce circulaire disposée autour de l’axe principal A. La coupelle 10 comporte une semelle plate circulaire supérieure 12, un moyeu de centrage 14 présentant une surface conique extérieure qui descend sous cette semelle en se resserrant, et un creux 16 formé sur le dessus de ce moyeu, qui reçoit de manière ajustée le cône de centrage 8 de la structure de caisse.A cup 10 made by molding a plastic material or an elastomer, forms a circular piece arranged around the main axis A. The cup 10 comprises an upper circular flat sole 12, a centering hub 14 having a surface external conical which descends under this sole while tightening, and a hollow 16 formed on the top of this hub, which receives the centering cone 8 of the body structure in an adjusted manner.
Le fond du creux 16 comporte trois clips 20 dirigés vers le haut, disposés autour de l’axe principal A, présentant chacun un crochet tourné vers l’extérieur comprenant une face inclinée vers l’extérieur en descendant, puis une face plate transversale.The bottom of the hollow 16 comprises three clips 20 directed upwards, arranged around the main axis A, each having a hook turned outwards comprising a face inclined towards the outside while descending, then a transverse flat face.
Le montage de la coupelle 10 sous la structure de caisse se fait simplement et sans outillage, en ajustant son creux 16 autour du cône de centrage 8 de cette structure, puis en la pressant vers le haut de manière à déformer vers l’axe principal A les clips 20 par un glissement de leur face inclinée sur le perçage central 18 du cône de centrage, puis un verrouillage de leur face transversale par un rappel élastique vers l’extérieur au-dessus de la tôle du perçage.The assembly of the cup 10 under the body structure is done simply and without tools, by adjusting its hollow 16 around the centering cone 8 of this structure, then by pressing it upwards so as to deform towards the main axis A the clips 20 by a sliding of their inclined face on the central bore 18 of the centering cone, then a locking of their transverse face by an elastic return towards the outside above the plate of the bore.
La
Le bras de suspension 30 comporte du côté intérieur du véhicule une plaque d’appui inférieur 32 formée par une tôle, comportant une face plate d’appui circulaire 34, et un rebord central de centrage 36 qui remonte légèrement.The suspension arm 30 comprises on the inside of the vehicle a lower support plate 32 formed by a sheet metal, comprising a flat circular support face 34, and a central centering rim 36 which rises slightly.
Un ressort de suspension 38 présente à ses extrémités des spires resserrées, avec en fonctionnement la spire inférieure 40 prenant appui sur la face plate d’appui 34 avec un centrage autour du rebord de centrage 36 de la plaque d’appui inférieur 32, et la spire supérieure 42 prenant appui sous la semelle 12 de la coupelle 10 avec un centrage autour du moyeu de centrage 14.A suspension spring 38 has tightened turns at its ends, with in operation the lower turn 40 resting on the flat bearing face 34 with a centering around the centering rim 36 of the lower bearing plate 32, and the upper turn 42 bearing under sole 12 of cup 10 with centering around centering hub 14.
Dans une première étape de montage du ressort 38 présentée
Dans une deuxième étape de montage du ressort 38 présentée
On notera que dans cette position le moyeu de centrage 14 de la coupelle 10 est suffisamment long pour que sa base reste engagée dans la spire supérieure 42 du ressort 38, ce qui empêche un basculement de ce ressort. La position du ressort 38 est sécurisée, l’opérateur peut effectuer ensuite différentes manœuvres en s’assurant qu’il restera dans cette position.It will be noted that in this position the centering hub 14 of the cup 10 is long enough for its base to remain engaged in the upper coil 42 of the spring 38, which prevents this spring from tilting. The position of the spring 38 is secure, the operator can then perform various maneuvers ensuring that he will remain in this position.
Dans une troisième étape de montage du ressort 38 présentée
On réalise ainsi en même temps la mise à hauteur du bras de suspension 30 et la compression du ressort 38 par le mouvement de ce bras, le ressort restant maintenu et guidée de manière entièrement sécurisée par ses éléments de fixation naturelles à ses deux extrémités, sans utiliser d’outillage complémentaire. On évite ainsi l’utilisation délicate et complexe d’un outillage qui pourrait basculer, avec dans le cas d’un ressort 38 plus long un risque de pincement de becs insérés entre des spires de ce ressort lors de sa compression maximum.At the same time, the suspension arm 30 is brought to a height and the spring 38 is compressed by the movement of this arm, the spring remaining held and guided in an entirely secure manner by its natural fastening elements at its two ends, without use additional tools. This avoids the delicate and complex use of a tool which could tip over, with, in the case of a longer spring 38, a risk of pinching of the jaws inserted between the coils of this spring during its maximum compression.
On notera que la coupelle 10 présentant un moyeu de guidage 14 plus long comporte un coût de fabrication faiblement augmenté, et ne change pas le procédé d’assemblage de cette coupelle sur le véhicule.It will be noted that the cup 10 having a longer guide hub 14 has a slightly increased manufacturing cost, and does not change the method of assembly of this cup on the vehicle.
La
Le montage de la coupelle 10 se fait de la même manière, en la pressant vers le haut avec un engagement du téton central 50 qui est ajusté dans le perçage central 18, puis une compression des bossages 52 jusqu’à ce qu’ils passent entièrement au-dessus de la tôle de ce perçage en réalisant un maintien par clipsage.The assembly of the cup 10 is done in the same way, by pressing it upwards with an engagement of the central stud 50 which is fitted in the central bore 18, then a compression of the bosses 52 until they pass completely above the sheet metal of this hole by securing it by clipping.
La
Le cône de centrage formé par la partie cylindrique centrale 60 et les ailettes axiales 62, comporte beaucoup moins de matière ce qui permet de réduire le poids et les coûts.The centering cone formed by the central cylindrical part 60 and the axial fins 62, comprises much less material which makes it possible to reduce the weight and the costs.
