Description

ESSIEU SOUPLE ARRIERE DE VEHICULE AUTOMOBILE COMPACT A BARRE PANHARD COMPRESSED COMPLETE MOTOR VEHICLE FLEXIBLE AXLE WITH PANHARD BAR
L'invention concerne un essieu souple arrière de véhicule automobile compact, à barre Panhard. Afin de réduire l'encombrement d'un essieu souple arrière et le rendre plus compact, une solution consiste à avancer la traverse vers l'avant du véhicule. Si l'essieu est alors réalisé afin de présenter une bonne raideur au roulis, un déficit de la raideur en torsion suivant l'axe longitudinal ou l'axe vertical du véhicule peut être observé, en particulier du côté où la barre Panhard est fixée à la caisse du véhicule.The invention relates to a compact rear axle of a compact motor vehicle, Panhard bar. In order to reduce the size of a rear flexible axle and make it more compact, one solution is to advance the crossbar towards the front of the vehicle. If the axle is then produced in order to have a good roll stiffness, a torsional stiffness deficit along the longitudinal axis or the vertical axis of the vehicle can be observed, in particular on the side where the Panhard bar is fixed to the vehicle body.
La figure 1 représente une vue de dessus d'un essieu souple à barre Panhard à traverse avancée. Cet essieu comprend deux bras oscillants longitudinaux 1 qui supportent chacun une roue 2 à une de leurs extrémités (une seule étant représentée), et qui sont articulés à leur autre extrémité 3 sur la carrosserie du véhicule (non représentée) .Figure 1 shows a top view of a flexible axle Panhard bar advanced cross. This axle comprises two longitudinal oscillating arms 1 which each support a wheel 2 at one of their ends (only one being shown), and which are articulated at their other end 3 to the vehicle body (not shown).
Ces bras sont reliés par une traverse 4. Pour des raisons de maintien et de guidage latéral du train arrière dans ses mouvements de suspension, une barre 5, dite barre Panhard, est disposée dans un plan horizontal proche de l'axe de rotation des roues arrière, et relie l'un des bras 1 à la caisse du véhicule.These arms are connected by a crossbar 4. For reasons of maintenance and lateral guidance of the rear axle in its suspension movements, a bar 5, said Panhard rod, is disposed in a horizontal plane close to the axis of rotation of the wheels rear, and connects one of the arms 1 to the vehicle body.
Sur la figure 1 , les axes X, Y, Z représentent les axes longitudinal, transversal et vertical du véhicule respectivement, l'axe longitudinal X étant dirigé vers l'arrière du véhicule. Les traits pointillés représentent le comportement de l'essieu lors d'un virage. Du fait de l'avancement de la traverse, le braquage α de la roue située du côté de la barre Panhard fixé à la caisse est important et très différent du braquage de l'autre roue, ce qui nuit à la tenue de route du véhicule.In Figure 1, the X, Y, Z axes represent the longitudinal, transverse and vertical axes of the vehicle respectively, the longitudinal axis X being directed towards the rear of the vehicle. The dashed lines represent the behavior of the axle during a turn. Due to the advancement of the crossbar, the turning α of the wheel located on the side of the Panhard bar attached to the body is large and very different from the steering of the other wheel, which affects the road holding of the vehicle .
L'invention vise à pallier ces inconvénients en proposant un essieu souple compact à barre Panhard permettant de maintenir un parallélisme plus rigoureux entre les deux roues afin d'améliorer la tenue de route du véhicule.The invention aims to overcome these disadvantages by providing a compact flexible axle Panhard bar to maintain a more rigorous parallelism between the two wheels to improve the road holding of the vehicle.
A cet effet, l'objet de l'invention concerne un essieu souple arrière compact comprenant deux bras longitudinaux reliés par une traverse, et une barre Panhard reliant un des bras longitudinaux à la caisse du véhicule, caractérisé en ce qu'il comprend une barre transversale supplémentaire, distincte de la traverse, dont les extrémités sont fixées aux bras longitudinaux, cette barre étant apte à supporter des efforts en traction et compression suivant son axe.For this purpose, the object of the invention relates to a compact rear axle comprising two longitudinal arms connected by a cross member, and a Panhard bar connecting one of the longitudinal arms to the vehicle body, characterized in that it comprises a bar additional cross section, distinct from the cross-member, the ends of which are fixed the longitudinal arms, this bar being adapted to withstand forces in tension and compression along its axis.
En travaillant en traction et compression, la barre transversale supplémentaire permet d'obtenir des braquages faibles et sensiblement symétriques des deux roues, et d'améliorer ainsi le parallélisme des roues.By working in tension and compression, the additional transverse bar makes it possible to obtain low and substantially symmetrical deflections of the two wheels, and thus to improve the parallelism of the wheels.
Dans un premier mode de réalisation, la traverse de l'essieu souple arrière selon l'invention présente un profil fermé. Il s'agit par exemple d'un tube dont la section est choisie en fonction des propriétés en flexion et torsion souhaitées. L'essieu présente alors un comportement à fort anti-roulis.In a first embodiment, the cross member of the rear flexible axle according to the invention has a closed profile. This is for example a tube whose section is chosen according to the desired flexural and torsional properties. The axle then exhibits a strong anti-roll behavior.
Avantageusement, la barre transversale supplémentaire est située de préférence en avant de la traverse. De préférence, cette barre est située le plus en avant possible du côté des extrémités des bras longitudinaux reliées à la caisse du véhicule, ceci afin de débattre verticalement avec une amplitude la plus faible possible. Un faible débattement vertical permet en effet d'implanter des éléments du véhicule, tel que l'échappement, à proximité de l'essieu, par exemple sous l'essieu. Dans ce mode de réalisation, la barre transversale supplémentaire travaille uniquement en compression et traction.Advantageously, the additional transverse bar is preferably located in front of the crossbar. Preferably, this bar is located as far forward as possible on the side of the ends of the longitudinal arms connected to the vehicle body, in order to debate vertically with the smallest possible amplitude. A low vertical movement makes it possible to implement elements of the vehicle, such as the exhaust, near the axle, for example under the axle. In this embodiment, the additional crossbar works only in compression and traction.
Dans une variante, la traverse présente un profil en V couché pointant vers l'arrière.In a variant, the cross member has a recessed V-shaped profile pointing backwards.
Dans un deuxième mode de réalisation, la traverse de l'essieu selon l'invention présente un profil ouvert, la barre transversale présentant une raideur prédéterminée en torsion.In a second embodiment, the cross beam of the axle according to the invention has an open profile, the transverse bar having a predetermined stiffness in torsion.
Une telle traverse à profil ouvert apporte une raideur sensible en flexion et très faible en torsion. Il est donc nécessaire de rajouter une barre qui travaille en torsion. Une telle barre, appelée barre anti-dévers, est généralement placée à l'intérieur du profil de la traverse.Such an open profile crossbar provides a significant stiffness in flexion and very low torsion. It is therefore necessary to add a bar that works in torsion. Such a bar, called anti-roll bar, is usually placed inside the profile of the crossbar.
Selon l'invention, avantageusement, la barre anti-dévers ajoutée fait aussi office de barre transversale supplémentaire, distincte de la traverse, et présente une raideur prédéterminée en torsion. A la différence des barres anti-dévers connues, la barre supplémentaire n'est pas placée à l'intérieur du profil de la traverse et travaille à la fois en compression et traction afin d'améliorer le parallélisme des roues, et en torsion à la manière d'une barre anti-devers classique. Dans le cas d'un profil en forme de V couché, la barre transversale supplémentaire est située du côté de la pointe du profil enAccording to the invention, advantageously, the added anti-roll bar also serves as an additional transverse bar, distinct from the crossbar, and has a predetermined torsional stiffness. Unlike the known anti-roll bars, the additional bar is not placed inside the profile of the cross member and works both in compression and traction to improve the parallelism of the wheels, and in torsion to the way of a classic anti-roll bar. In the case of a recumbent V-shaped profile, the additional crossbar is located on the tip side of the profile.
V. Cette position particulière de la barre supplémentaire par rapport à la forme du profil de la traverse permet de limiter la flexion subie par la barre supplémentaire, et facilite sa tenue en endurance.V. This particular position of the additional bar relative to the shape of the profile of the cross member limits the flexion experienced by the additional bar, and facilitates its resistance in endurance.
L'invention est maintenant décrite en référence aux dessins annexés, non limitatifs, dans lesquels : la figure 1 est une vue de dessus montrant le comportement d'un essieu souple arrière selon l'art antérieur ; la figure 2 est une vue de côté d'un essieu souple arrière selon l'invention ; la figure 3 est une vue de dessus de l'essieu représenté figure 2 montrant le comportement de cet essieu ; - la figure 4 est une vue de côté d'un autre mode de réalisation d'un essieu selon l'invention.The invention is now described with reference to the accompanying non-limiting drawings, in which: FIG. 1 is a view from above showing the behavior of a rear flexible axle according to the prior art; Figure 2 is a side view of a rear flexible axle according to the invention; Figure 3 is a top view of the axle shown in Figure 2 showing the behavior of this axle; - Figure 4 is a side view of another embodiment of an axle according to the invention.
L'essieu souple arrière compact représenté sur les figures 2 et 3 comprend deux bras longitudinaux 10, une traverse 1 1 et une barre Panhard 12. La traverse est située le plus en avant possible afin de limiter l'encombrement de l'essieu.The compact rear axle shown in Figures 2 and 3 comprises two longitudinal arms 10, a cross member 1 1 and a Panhard bar 12. The cross is located as far forward as possible to limit the size of the axle.
Chaque bras longitudinal comprend une extrémité avant 13 montée à pivot sur la caisse du véhicule (non représentée) autour d'un axe sensiblement parallèle à l'axe de rotation des roues, et une extrémité arrière 14 supportant une roue 15 tournant autour d'un axe 16 de rotation.Each longitudinal arm comprises a front end 13 mounted to pivot on the vehicle body (not shown) about an axis substantially parallel to the axis of rotation of the wheels, and a rear end 14 supporting a wheel 15 rotating about a 16 axis of rotation.
Les extrémités de la traverse 1 1 sont fixées sur les bras longitudinaux 10.The ends of the cross member 1 1 are fixed on the longitudinal arms 10.
La barre Panhard 12 est disposée dans un plan horizontal proche de l'axe de rotation des roues arrière, et s'étend entre la traverse 1 1 et les roues, une de ses extrémités étant fixée à un bras longitudinal, son autre extrémité étant solidaire de la caisse du véhicule.The Panhard bar 12 is disposed in a horizontal plane close to the axis of rotation of the rear wheels, and extends between the cross member 1 1 and the wheels, one of its ends being fixed to a longitudinal arm, its other end being secured. of the vehicle body.
Dans le mode de réalisation de la figure 2, la traverse présente un profil fermé en forme de V couché pointant vers l'arrière du véhicule. Une telle traverse présente une bonne inertie suivant l'axe X, et une inertie moyenne suivant l'axe Z.In the embodiment of Figure 2, the cross member has a closed V-shaped profile lying towards the rear of the vehicle. Such a crosshead has good inertia along the X axis, and an average inertia along the Z axis.
Selon l'invention, l'essieu est pourvu d une barre transversale supplémentaire 17 distincte de la traverse. Dans l'exemple de la figure 2, cette barre 17 est située en avant de la traverse et permet de compenser le manque d'inertie de la traverse suivant l'axe Z. Cette barre est de préférence située le plus en avant possible afin de présenter un faible débattement suivant l'axe Z du véhicule lors des chocs et rebonds de l'essieu.According to the invention, the axle is provided with an additional transverse bar 17 distinct from the crossbar. In the example of the figure 2, this bar 17 is located in front of the cross-member and makes it possible to compensate for the lack of inertia of the cross member along the axis Z. This bar is preferably located as far forward as possible so as to have a low clearance according to the Z axis of the vehicle during shocks and rebounds of the axle.
Tel que visible sur la figure 3, cette barre permet d'améliorer le parallélisme des roues lors d'un virage, les angles α de braquage des roues étant faibles et sensiblement symétriques. Dans ce mode de réalisation, la barre supplémentaire 17 travaillant uniquement en traction et compression, doit être réalisée de manière à supporter ces contraintes.As can be seen in FIG. 3, this bar makes it possible to improve the parallelism of the wheels during a turn, the steering angle α of the wheels being small and substantially symmetrical. In this embodiment, the additional bar 17 working only in tension and compression, must be made to withstand these constraints.
Sur la figure 4, les éléments identiques à ceux de la figure 2 sont désignés par les mêmes références.In Figure 4, the elements identical to those of Figure 2 are designated by the same references.
Dans le mode de réalisation de la figure 4, la traverse 1 1 ' présente un profil ouvert en V couché qui pointe en direction de la barre additionnelle 17', distincte de la traverse. Cette barre additionnelle 17' est de préférence placée entre la traverse et les extrémités avant de l'essieu, tel que représenté sur la figure 4, de manière à en limiter le débattement vertical. Dans ce mode de réalisation, la barre additionnelle 17' doit être réalisée de manière à pouvoir supporter des contraintes à la fois en traction et compression afin d'assurer un comportement symétrique des roues, et en flexion, afin de compenser le manque de raideur en flexion de la traverse à profil ouvert. A cet effet, elle présente une raideur pré- déterminée en torsion.In the embodiment of Figure 4, the cross 1 1 'has an open V-shaped profile which points in the direction of the additional bar 17', distinct from the cross. This additional bar 17 'is preferably placed between the cross member and the front ends of the axle, as shown in Figure 4, so as to limit the vertical movement. In this embodiment, the additional bar 17 'must be made in such a way as to be able to withstand stresses both in tension and compression in order to ensure a symmetrical behavior of the wheels, and in bending, in order to compensate for the lack of stiffness in bending of the open profile cross member. For this purpose, it has a predetermined stiffness in torsion.
Dans une variante non représentée de ce deuxième mode de réalisation, on pourrait envisager que la barre supplémentaire soit située entre la traverse et les extrémités arrière de l'essieu, le profil en V de la traverse pointant vers l'arrière. Bien entendu, la traverse pourrait présenter d'autres formes de profil en fonction des propriétés recherchées pour la traverse. In a variant not shown of this second embodiment, it could be envisaged that the additional bar is located between the cross member and the rear ends of the axle, the V-shaped profile of the crossbar pointing rearwardly. Of course, the cross member could have other shapes of profile depending on the desired properties for the cross.
