Abstract
Description
La présente invention concerne un essieu porteur de véhicule automobile qui comporte une traverse déformable et deux bras en tole pliee qui sont fixés à la traverse et sur chacun desquels est monté un axe de roue. Un essieu de ce genre est décrit dans la demande de brevet français 83 10350.The present invention relates to a carrier axle of a motor vehicle which comprises a deformable cross member and two arms of folded sheet metal which are fixed to the cross member and on each of which is mounted a wheel axle. An axle of this kind is described in French patent application 83 10350.
La présente invention a pour objet un essieu de ce type qui peut être relativement peu rigide et permet ainsi de grands débattements.The subject of the present invention is an axle of this type which can be relatively not very rigid and thus allows large deflections.
L'essieu selon l'invention est caractérisé en ce que les extrémités de la traverse sont délimitées par deux plans obliques par rapport à l'axe longitudinal de la traverse et sont fermées par deux fonds plats sur lesquels les bras sont soudés.The axle according to the invention is characterized in that the ends of the cross-member are delimited by two oblique planes with respect to the longitudinal axis of the cross-member and are closed by two flat bottoms on which the arms are welded.
Dans un mode de réalisation particulier de l'invention, une barre anti-roulis est disposée à l'intérieur de la traverse, ses extrémités traversant les fonds plats et étant soudées aux parois extérieures des bras. Cette barre travaille à la torsion en parallèle avec la traverse, ce qui permet de prévoir une traverse plus souple et plus légère.In a particular embodiment of the invention, an anti-roll bar is disposed inside the cross member, its ends passing through the flat bottoms and being welded to the outer walls of the arms. This bar works with torsion in parallel with the cross-member, which makes it possible to provide a more flexible and lighter cross-member.
La caisse du véhicule est généralement reliée à l'essieu par l'intermédiaire de paliers élastiques montés sur des axes solidaires de l'essieu. Selon une caractéristique complémentaire de l'invention qui permet de répondre facilement à cette condition, les extrémités de la barre de torsion font saillie par rapport aux bras et ces extrémités en porte-a-faux servent d'axe d'articulation pour des paliers élastiques supportant la caisse du véhicule.The vehicle body is generally connected to the axle by means of elastic bearings mounted on axes integral with the axle. According to an additional characteristic of the invention which makes it possible to easily meet this condition, the ends of the torsion bar protrude relative to the arms and these cantilevered ends serve as a hinge axis for elastic bearings supporting the vehicle body.
On a décrit ci-apres, à titre d'exemple non limitatif, un mode de réalisation de l'essieu porteur selon l'invention, avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en perspective de l'es
sieu;
La Figure 2 est une vue en perspective de l'une
des extrémités de la traverse;
La Figure 3 est une vue en perspective montrant
une extrémité de la traverse et le bras fixé
sur cette extrémité;
La Figure 4 est une vue en coupe horizontale de
l'une des extrémités de l'essieu et montre la
liaison de cette extrémité avec la caisse du
véhicule.An embodiment of the carrying axle according to the invention has been described below, by way of non-limiting example, with reference to the accompanying drawings in which
Figure 1 is a perspective view of the es
god;
Figure 2 is a perspective view of one
ends of the sleeper;
Figure 3 is a perspective view showing
one end of the cross member and the arm attached
on this end;
Figure 4 is a horizontal sectional view of
one end of the axle and shows the
connection of this end with the body of the
vehicle.
Tel qu'il est représenté au dessin, l'essieu selon l'invention comporte une traverse 1 à chacune des extrémités de laquelle est fixé un bras 2. As shown in the drawing, the axle according to the invention comprises a cross member 1 at each end of which is fixed an arm 2.
La traverse 1 est constituée par une pièce en forme d'auge en tle emboutie. A chacune de ses extrémités, la traverse 1 est coupée par un plan oblique par rapport à l'axe longitudinal de la traverse; chaque extrémité de la traverse qui présente la forme d'un triangle à sommet arrondi est cloisonnée par un fond plat 3.The cross member 1 is constituted by a piece in the form of a stamped trough. At each of its ends, the cross member 1 is cut by an oblique plane with respect to the longitudinal axis of the cross member; each end of the crosspiece which has the shape of a triangle with a rounded top is partitioned by a flat bottom 3.
Chacun des bras 2 est formé de deux demi-coquilles embouties qui présentent la forme d'un U et sont soudées l'une à l'autre pour constituer le corps de bras. L'une des extrémités de ce bras est soudée au fond 3 en laissant libre la portion d'extrémité intérieure de ce fond, comme indiqué en 3a, afin d'éviter tout risque de rupture dans la liaison. L'extrémité libre du bras est fermée par un fond 4. Au voisinage de cette extrémité libre, le bras est traversé par un axe de roue arrière 5 qui fait saillie par rapport à la face latérale extérieure du bras et par un axe support d'amortisseur 6 qui fait saillie par rapport à la face latérale intérieure de ce bras. Les deux axes sont reliés entre eux par un renfort intérieur 7 et un renfort extérieur 8.Each of the arms 2 is formed from two stamped half-shells which have the shape of a U and are welded to one another to constitute the arm body. One end of this arm is welded to the bottom 3, leaving the interior end portion of this bottom free, as indicated in 3a, in order to avoid any risk of rupture in the connection. The free end of the arm is closed by a bottom 4. In the vicinity of this free end, the arm is crossed by a rear wheel axle 5 which projects relative to the external lateral face of the arm and by a support axle. shock absorber 6 which projects relative to the inner lateral face of this arm. The two axes are interconnected by an internal reinforcement 7 and an external reinforcement 8.
Une barre anti-roulis 9 est disposée à l'intérieur de la traverse; elle traverse les fonds 3 et la paroi extérieure de chaque bras sur laquelle elle est soudée par l'intermédiaire d'une rondelle 10. Les portions d'extrémité de cette barre ont un diamètre plus grand que celui de la portion intermédiaire qui est calculée pour que cette portion intermédiaire remplisse la fonction anti-roulis; ces portions d'extrémité qui sont obtenues par refoulement et sont soudées sur les bras par l'intermédiaire des rondelles 10, remplissent les fonctions d'axes d'articulation et de liaison avec la caisse du véhicule. Un trou d'allègement 11 y est effectué.An anti-roll bar 9 is arranged inside the cross member; it crosses the bottoms 3 and the outer wall of each arm to which it is welded by means of a washer 10. The end portions of this bar have a larger diameter than that of the intermediate portion which is calculated for that this intermediate portion fulfills the anti-roll function; these end portions which are obtained by delivery and are welded to the arms by means of the washers 10, fulfill the functions of articulation axes and of connection with the body of the vehicle. A lightening hole 11 is made there.
La souplesse de liaison de l'essieu avec la caisse 12 est obtenue grâce a des paliers élastiques 13 montés sur des extrémités en porte-à-faux 9a de la barre de torsion 9 et comprenant un silent-bloc 14 ainsi que des rondelles en élastomère 15 serrées entre deux rondelles en acier 16.The flexibility of connection of the axle with the body 12 is obtained by means of elastic bearings 13 mounted on the overhanging ends 9a of the torsion bar 9 and comprising a silent block 14 as well as elastomer washers 15 clamped between two steel washers 16.
L'essieu qui vient d'être décrit offre de plus grands débattements que la plupart des essieux connus, ce qui peut permettre une plus grande souplesse dans les liaisons au sol pour un plus grand confort.The axle which has just been described offers greater travel than most known axles, which can allow greater flexibility in the connections to the ground for greater comfort.
I1 va de soi que la présente invention ne doit pas etre considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
