Description
TRAIN ARRIERE A TRAVERSE DEFORMABLE COMPORTANT DES COMBINES TOURNES VERS L'AVANT, FIXES AU BRAS DE SUSPENSION SOUS L'ARTICULATION La présente invention concerne un train arrière à traverse déformable pour véhicule automobile, ainsi qu'un véhicule automobile équipé d'un tel train arrière. Les véhicules automobiles comportent généralement un train arrière fixé sous la caisse, qui supporte et guide les roues arrière en permettant un débattement des suspensions arrière. Un type de train arrière connu appelé train à traverse déformable, présenté notamment par le document FR-A1-2888559, comporte un essieu présentant une forme générale en « H », comprenant de chaque coté du véhicule un bras de suspension disposé longitudinalement. L'avant des bras de suspension est relié à la caisse du véhicule par une liaison élastique pouvant pivoter suivant un axe sensiblement transversal, l'arrière de ces bras supportant le moyeu de la roue. La barre centrale du « H » constitue une traverse déformable disposée transversalement, dont chaque extrémité est fixée de manière rigide à l'intérieur des bras de suspension. Cette traverse déformable maintient la géométrie des bras de suspension, tout en assurant par une déformation en torsion suivant son axe, la fonction de barre anti-dévers qui limite l'angle de roulis de la caisse. La caisse du véhicule est supportée par des ressorts de suspension qui prennent appui sur un plateau formant un panier disposé à l'arrière de chaque bras, du côté intérieur. Un amortisseur hydraulique télescopique est généralement installé en parallèle, à l'intérieur ou sur le côté de ce ressort. Un problème qui se pose avec ce type de train arrière est que les plateaux arrière supportant les ressorts de suspension, réalisés 30 généralement en tôle suffisamment résistante pour supporter la masse de la caisse du véhicule qui s'applique par les ressorts, sont relativement lourds.The present invention relates to a rear axle with a deformable cross member for a motor vehicle, as well as to a motor vehicle equipped with such a rear axle. . Motor vehicles generally include a rear axle fixed under the body, which supports and guides the rear wheels by allowing a movement of the rear suspensions. A known type of rear train called deformable cross train, presented in particular by the document FR-A1-2888559 comprises an axle having a general shape in "H", comprising on each side of the vehicle a suspension arm arranged longitudinally. The front of the suspension arms is connected to the vehicle body by an elastic connection pivotable along a substantially transverse axis, the rear of these arms supporting the hub of the wheel. The central bar of the "H" is a transversely deformable cross member, each end of which is rigidly fixed inside the suspension arms. This deformable crosspiece maintains the geometry of the suspension arms, while ensuring torsional deformation along its axis, the anti-roll bar function which limits the roll angle of the body. The vehicle body is supported by suspension springs which rest on a tray forming a basket disposed at the rear of each arm, the inner side. A telescopic hydraulic damper is generally installed in parallel, inside or on the side of this spring. A problem with this type of rear axle is that the rear trays supporting the suspension springs, generally made of sheet metal sufficiently strong to support the mass of the vehicle body which is applied by the springs, are relatively heavy.
Cette masse fixée sur chaque bras, qui peut être de l'ordre de 1,4kg, ajoute du poids au véhicule. De plus étant non suspendue et montée à l'extrémité arrière des bras de suspension, elle décrit un mouvement de grande amplitude lors des oscillations de la suspension.This mass fixed on each arm, which can be of the order of 1.4 kg, adds weight to the vehicle. In addition being unsprung and mounted at the rear end of the suspension arms, it describes a movement of large amplitude during oscillations of the suspension.
Par ailleurs les ressorts disposés sensiblement verticalement sur le train arrière, occupent une place derrière chaque roue prenant un volume dans le coffre. La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.Furthermore the springs arranged substantially vertically on the rear axle, occupy a place behind each wheel taking a volume in the trunk. The present invention is intended to avoid these disadvantages of the prior art.
Elle propose à cet effet un train arrière pour véhicule automobile équipé d'un essieu à traverse déformable comportant de chaque côté un bras de suspension longitudinal fixé à l'avant à la caisse du véhicule par une articulation, et une traverse déformable comprenant ses extrémités fixées de manière rigide aux bras de suspension, caractérisé en ce qu'il comporte de chaque côté un combiné équipé de ressorts, disposé sensiblement longitudinalement, dont l'extrémité avant est fixée à la caisse du véhicule, et l'extrémité arrière au bras de suspension en dessous de son articulation, les ressorts étant comprimés quand ces combinés travaillent en traction. Un avantage de ce train arrière est que sur un essieu à traverse déformable simple à produire, on peut retirer les plateaux à l'arrière des bras prévus habituellement pour supporter les ressorts, ce qui réduit la masse de ce train, en particulier la masse non suspendue, ainsi que les coûts de fabrication. Le train arrière selon l'invention peut de plus comporter une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles. Avantageusement, les combinés de suspension comportent à leurs extrémités des pivots permettant la fixation sur la caisse ou sur le bras de suspension, comprenant chacun un axe disposé transversalement.It proposes for this purpose a rear axle for a motor vehicle equipped with a axle with deformable cross member having on each side a longitudinal suspension arm fixed at the front to the vehicle body by a hinge, and a deformable cross member including its fixed ends. rigidly to the suspension arms, characterized in that it comprises on each side a combined with springs, arranged substantially longitudinally, whose front end is fixed to the vehicle body, and the rear end to the suspension arm below its articulation, the springs being compressed when these handsets work in traction. An advantage of this rear axle is that on a simple deformable cross axle to produce, we can remove the trays behind the arms usually provided to support the springs, which reduces the weight of this train, particularly the mass not suspended, as well as manufacturing costs. The rear axle according to the invention may further comprise one or more of the following features, which may be combined with one another. Advantageously, the suspension combinations have at their ends pivots for attachment to the body or the suspension arm, each comprising a transverse axis.
En particulier, le pivot avant peut comporter une chape comprenant une patte prévue pour être fixée sur la face arrière d'une tôle de plancher.In particular, the front pivot may comprise a yoke comprising a tab adapted to be fixed on the rear face of a floor plate.
Avantageusement, le pivot arrière dispose d'une chape arrière fixée à l'avant du bras de suspension. L'axe du pivot arrière peut être sensiblement aligné sur le plan inférieur du bras de suspension disposé horizontalement.Advantageously, the rear pivot has a rear clevis fixed to the front of the suspension arm. The axis of the rear pivot may be substantially aligned with the lower plane of the horizontally disposed suspension arm.
Avantageusement, l'axe principal du combiné de suspension est sensiblement dans le plan vertical médian du bras de suspension. Avantageusement, le combiné de suspension comporte un cylindre extérieur dont l'extrémité avant est fixée à la caisse du véhicule, et une tige axiale coulissante qui sort de ce cylindre vers l'arrière.Advantageously, the main axis of the suspension unit is substantially in the median vertical plane of the suspension arm. Advantageously, the suspension unit comprises an outer cylinder whose front end is fixed to the body of the vehicle, and a sliding axial rod coming out of this cylinder rearwardly.
Avantageusement, le combiné de suspension comporte un amortisseur hydraulique intégré. En particulier, le train arrière peut comporter de chaque côté un deuxième combiné de suspension agissant en parallèle du premier combiné. L'invention a aussi pour objet un véhicule automobile disposant d'un train arrière équipé d'un essieu à traverse déformable comportant de chaque côté un bras de suspension longitudinal fixé à l'avant à la caisse du véhicule par une articulation, et une traverse déformable comprenant ses extrémités fixées de manière rigide aux bras de suspension, ce train arrière comprenant l'une quelconque des caractéristiques précédentes.Advantageously, the suspension unit comprises an integrated hydraulic damper. In particular, the rear axle may comprise on each side a second suspension unit acting in parallel with the first handset. The invention also relates to a motor vehicle having a rear axle equipped with a deformable cross axle having on each side a longitudinal suspension arm fixed to the front of the vehicle body by a hinge, and a cross member deformable member comprising its ends rigidly attached to the suspension arms, said rear axle comprising any one of the preceding features.
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 : - la figure 1 est une vue en perspective d'un train arrière selon l'invention ; - la figures 2 est une vue de côté de ce train arrière comprenant le bras de suspension au repos ; et - la figure 3 est une vue de côté de ce train arrière comprenant la suspension enfoncée. Les figures 1 et 2 présentent un essieu 2 comprenant de chaque côté 30 un bras de suspension 4 disposé longitudinalement, et une traverse déformable 6 réalisée en tôle, dont les extrémités sont soudées sur le côté intérieur dans la partie centrale de ces bras. L'extrémité avant de chaque bras 4 reçoit un anneau soudé d'une articulation 8, comprenant un axe disposé transversalement qui est sensiblement aligné sur le plan supérieur de ce bras quand il est horizontal. Les anneaux des articulations 8 reçoivent des articulations élastiques présentant l'axe central fixé sous la caisse du véhicule, afin de permettre un pivotement de l'essieu 2 autour de ces articulations tout en filtrant les vibrations.The invention will be better understood and other features and advantages will emerge more clearly on reading the following description given by way of example, with reference to the appended drawings in which: FIG. 1 is a perspective view of a rear axle according to the invention; - Figure 2 is a side view of the rear axle comprising the suspension arm at rest; and - Figure 3 is a side view of the rear train comprising the depressed suspension. Figures 1 and 2 show an axle 2 comprising on each side 30 a suspension arm 4 disposed longitudinally, and a deformable cross member 6 made of sheet metal, whose ends are welded to the inner side in the central portion of these arms. The front end of each arm 4 receives a welded ring of a hinge 8, comprising a transversely arranged axis which is substantially aligned with the upper plane of this arm when it is horizontal. The rings of the joints 8 receive elastic joints having the central axis fixed under the vehicle body, to allow a pivoting of the axle 2 around these joints while filtering the vibrations.
La partie arrière de chaque bras 4 comporte une platine porte-moyeu 10 perpendiculaire à la direction transversale, formée par une tôle pliée comprenant des renforts latéraux soudés à ce bras, qui dispose de perçages recevant le moyeu de la roue arrière. De chaque côté du train arrière, un combiné 20 comportant le ressort de suspension, présentant un axe principal disposé longitudinalement, a son extrémité avant fixée à la caisse du véhicule et son extrémité arrière fixée à l'avant du bras de suspension 4. L'axe principal du combiné de suspension 20 est sensiblement dans le plan vertical passant par l'axe médian du bras de suspension 4.The rear part of each arm 4 comprises a hub plate 10 perpendicular to the transverse direction, formed by a folded sheet comprising lateral reinforcements welded to this arm, which has holes receiving the hub of the rear wheel. On each side of the rear axle, a handset 20 comprising the suspension spring, having a main axis arranged longitudinally, has its front end fixed to the vehicle body and its rear end fixed to the front of the suspension arm 4. The main axis of the suspension assembly 20 is substantially in the vertical plane passing through the median axis of the suspension arm 4.
Le combiné de suspension 20 comporte un cylindre extérieur 22 dont l'extrémité avant est fixée dans une chape formée par une patte en tôle pliée 24, vissée sur la face arrière d'une tôle de plancher 14 disposée sensiblement verticalement sous les sièges arrière du véhicule, en arrière des pieds des passagers ce des sièges.The suspension assembly 20 comprises an outer cylinder 22 whose front end is fixed in a clevis formed by a folded sheet metal tab 24, screwed on the rear face of a floor plate 14 disposed substantially vertically under the rear seats of the vehicle , behind the feet of the passengers this seats.
Une tige axiale 28 coulissant dans le combiné de suspension 20, pour comprimer le ressort de suspension quand elle recule, comporte son extrémité arrière fixée à l'intérieur d'une chape formée par deux tôles parallèles soudées à l'avant du bras de suspension 4. L'axe de la chape arrière 30 est sensiblement aligné sur le plan inférieur du bras de suspension 4 disposé horizontalement.An axial rod 28 sliding in the suspension assembly 20, to compress the suspension spring when it retreats, has its rear end fixed inside a yoke formed by two parallel sheets welded to the front of the suspension arm 4 The axis of the rear yoke 30 is substantially aligned with the lower plane of the suspension arm 4 disposed horizontally.
On dispose ainsi le combiné de suspension 20 dans une position relativement haute, permettant de préserver la garde au sol en dessous de ce combiné. De plus avec le cylindre extérieur 22 fixé à la caisse du véhicule et la tige arrière 28 fixée au bras de suspension 4, on réduit la masse non suspendue car cette tige dispose d'un poids inférieur à celui du cylindre. Le combiné de suspension 20 est disposé à l'intérieur d'un longeron arrière de la caisse du véhicule qui supporte le coffre de cette caisse, et parallèlement à ce longeron avec un écartement suffisant permettant de loger dans ce combiné le ressort de suspension comprenant un diamètre adapté pour donner la force de rappel nécessaire. On notera qu'un espace important est laissé libre à l'arrière de la tôle de plancher vertical 14, entre les deux combinés de suspension 20, pour y loger notamment le réservoir de carburant qui se trouve habituellement à cette place.This provides the suspension unit 20 in a relatively high position, to preserve the ground clearance below the handset. In addition with the outer cylinder 22 attached to the vehicle body and the rear rod 28 attached to the suspension arm 4, the unsprung mass is reduced because this rod has a weight less than that of the cylinder. The suspension assembly 20 is disposed inside a rear spar of the vehicle body which supports the trunk of this body, and parallel to this spar with a sufficient spacing to accommodate in this combined the suspension spring comprising a diameter adapted to give the necessary restoring force. It will be noted that a large space is left free at the rear of the vertical floor plate 14, between the two suspension units 20, to house in particular the fuel tank which is usually in this place.
Les axes 26, 30 des chapes avant et arrière du combiné de suspension disposés transversalement, constituent des articulations qui permettent d'appliquer uniquement un effort de traction axial entre les deux parties mobiles de ce combiné, sans induire d'efforts transversaux, ce qui permet d'éviter des frottements parasites dans le combiné ainsi que des usures 20 prématurées. La hauteur H entre l'axe de l'articulation 8 qui est le point de pivotement du bras de suspension 4, et l'axe du combiné de suspension 20, mesurée perpendiculairement à cet axe de combiné, forme un bras de levier qui donne une traction vers l'arrière sur la tige 28 du combiné de suspension 20, quand ce bras pivote vers le haut. On obtient une certaine démultiplication entre l'effort appliqué sur la roue, et celui transmis sur le combiné 20 et appliqué sur le ressort de suspension, qui donne en retour une force de rappel légèrement variable du bras de suspension 4 vers le bas.The axles 26, 30 of the front and rear clevises of the suspension assembly arranged transversely constitute articulations which make it possible to apply only an axial traction force between the two moving parts of this handset, without inducing transverse forces, which allows to avoid parasitic friction in the handset as well as premature wear. The height H between the axis of the articulation 8 which is the pivot point of the suspension arm 4, and the axis of the suspension combination 20, measured perpendicularly to this handset axis, form a lever arm which gives a pull back on the rod 28 of the suspension assembly 20, when the arm pivots upwards. Some reduction is obtained between the force applied on the wheel and that transmitted on the handset 20 and applied to the suspension spring, which gives back a slightly variable restoring force of the suspension arm 4 downwards.
On notera que pour un même débattement du bras de suspension 4, la course de la tige 28 du combiné de suspension 20 est nettement réduite par rapport à celle du ressort de suspension dans le cas d'un montage classique à l'arrière de ce bras, à cause du levier correspondant à la hauteur H qui est très court. Cette course réduite donne un combiné de suspension compact et court, qui peut être plus facilement placé entre l'extrémité avant du bras de suspension 4 et la tôle de plancher vertical 14. Cette course réduite de la tige 28 peut aussi permettre un plus grand débattement de la suspension.La figure 3 présente la suspension arrière du véhicule fortement comprimée, les bras de suspension 4 ayant pivoté autour de leurs articulations 8, et les tiges arrière 28 des combinés de suspension 20 ayant fortement reculé en comprimant les ressorts de suspension internes. L'axe de la chape arrière 30 ayant reculé en arrière de l'axe de l'articulation 8, on obtient une hauteur H entre ces deux axes qui est réduite par rapport à la hauteur initiale, ce qui modifie légèrement le bras de levier appliquant la traction sur le ressort de suspension. La démultiplication entre l'inclinaison du bras de suspension 4 et l'étirement du combiné de suspension est modifiée. En adaptant la position longitudinale de l'axe de la chape arrière 30 sur le bras de suspension 4, par rapport à l'axe de l'articulation 8, on peut ainsi obtenir une hauteur H qui augmente ou diminue pour un enfoncement de ce bras, et modifier légèrement la courbe d'effort de rappel avec un ressort hélicoïdal du combiné de suspension 20 disposant d'une raideur constante. Selon un mode de réalisation, le combiné de suspension 20 peut comporter un amortisseur hydraulique disposé suivant son axe, ce qui forme un ensemble compact comprenant les deux fonctions intégrées.Note that for the same movement of the suspension arm 4, the stroke of the rod 28 of the suspension unit 20 is significantly reduced compared to that of the suspension spring in the case of a conventional assembly at the rear of this arm because of the lever corresponding to the height H which is very short. This reduced stroke gives a compact and short suspension combination, which can be more easily placed between the front end of the suspension arm 4 and the vertical floor plate 14. This reduced stroke of the rod 28 may also allow greater travel. Figure 3 shows the rear suspension of the heavily compressed vehicle, the suspension arms 4 having pivoted about their hinges 8, and the rear rods 28 of the suspension assemblies 20 having strongly receded by compressing the inner suspension springs. The axis of the rear clevis 30 having retracted behind the axis of the hinge 8, a height H between these two axes is obtained which is reduced with respect to the initial height, which slightly modifies the applying lever arm. traction on the suspension spring. The reduction between the inclination of the suspension arm 4 and the stretching of the suspension combo is changed. By adapting the longitudinal position of the axis of the rear clevis 30 on the suspension arm 4 relative to the axis of the hinge 8, it is thus possible to obtain a height H which increases or decreases for a depression of this arm , and slightly modify the return force curve with a coil spring of the suspension combination 20 having a constant stiffness. According to one embodiment, the suspension unit 20 may comprise a hydraulic damper disposed along its axis, which forms a compact assembly comprising the two integrated functions.
En variante le combiné de suspension 20 peut comporter seulement un ressort de suspension, l'amortisseur hydraulique étant disposé à l'extérieur. L'amortisseur peut en particulier être monté de manière classique verticalement à l'arrière du bras de suspension 4, sa base étant fixée à un support horizontal 12 tourné vers l'intérieur présentant un perçage de fixation.Alternatively the suspension combination 20 may comprise only a suspension spring, the hydraulic damper being disposed outside. The damper may in particular be mounted vertically conventionally at the rear of the suspension arm 4, its base being fixed to a horizontal support 12 facing inwardly having a fixing bore.
En variante on peut disposer de chaque côté du train arrière, deux combinés agissant en parallèle pour additionner les raideurs de leurs ressorts, en particulier pour les véhicules les plus chargés. On peut notamment disposer un deuxième combiné sensiblement horizontalement au-dessus du bras de suspension, son extrémité avant étant fixée à un point du bras situé au-dessus de l'axe d'articulation de ce bras, et son extrémité arrière à la caisse du véhicule de manière à exercer une traction sur ce combiné. D'une manière générale on réalise ainsi des bras de suspension 4 comprenant une fabrication simplifiée et plus économique, qui peuvent comporter moins de courbures, en particulier si la largeur des roues n'est pas très importante ce qui dégage une place derrière ces roues.Alternatively one can have on each side of the rear axle, two handsets acting in parallel to add the stiffness of their springs, especially for the most loaded vehicles. In particular, a second handset may be disposed substantially horizontally above the suspension arm, its front end being fixed to a point of the arm situated above the hinge axis of this arm, and its rear end to the body of the vehicle so as to exert traction on this handset. In general, suspension arms 4 are thus produced which comprise simplified and more economical manufacturing, which may have fewer curvatures, in particular if the width of the wheels is not very large, which gives rise to a space behind these wheels.
