SUSPENSION DE ROW DU TYPE A BRAS TIRE POUR VHHICULE
AUTOMOBILE
L'invention concerne une suspension de roue du type à bras tiré pour véhicule automobile, en particulier d'une roue arrière motrice d'un véhicule automobile tous terrains, notamment un véhicule blindé léger à usage militaire.ROW SUSPENSION OF VEHICLE ARM TYPE
AUTOMOTIVE
The invention relates to a wheel suspension of the pulled arm type for a motor vehicle, in particular a rear drive wheel of an all-terrain motor vehicle, in particular a light armored vehicle for military use.
De façon classique, une suspension de ce type comprend un bras dont une extrémité est montée sur la caisse du véhicule et dont l'autre extrémité est portée par le moyeu de la roue, un vérin ou un moyen à ressort de suspension étant également monté entre ce bras et la caisse du véhicule. Conventionally, a suspension of this type comprises an arm, one end of which is mounted on the vehicle body and the other end of which is carried by the wheel hub, a jack or a suspension spring means also being mounted between this arm and the body of the vehicle.
Lorsque la roue est motrice, il faut transmettre un couple de rotation au moyeu de la roue à partir d'une boîte de transmission ou de liaison fixée sur la caisse du véhicule, et l'on peut pour cela prévoir un train d'engrenages à l'intérieur du bras précité. When the wheel is driving, it is necessary to transmit a torque to the wheel hub from a gearbox or linkage fixed to the vehicle body, and one can for this provide a gear train to inside the aforementioned arm.
Dans ces conditions, le montage et le réglage de cette suspens ion se révèlent relativement longs et compliqués. Under these conditions, the mounting and adjustment of this suspense ion prove to be relatively long and complicated.
L'invention a notamment pour but de simplifier ce montage et ces réglages. The object of the invention is in particular to simplify this mounting and these adjustments.
Elle a pour objet une suspension du type précité, constituant un ensemble modulaire dont l'assemblage et le réglage puissent être effectués avant montage de cet ensemble sur le véhicule. It relates to a suspension of the aforementioned type, constituting a modular assembly whose assembly and adjustment can be carried out before mounting of this assembly on the vehicle.
Elle a encore pour objet une suspension de ce type, constituant un ensemble modulaire qui puisse être utilisé sur le côté gauche et sur le côté droit du véhicule. It also relates to a suspension of this type, constituting a modular assembly which can be used on the left side and on the right side of the vehicle.
Elle propose donc une suspension de roue du type à bras tiré pour véhicule automobile, comprenant un bras de suspension dont une première extrémité est montée sur la caisse du véhicule et dont une seconde extrémité est portée par le moyeu d'une roue, caractérisée en ce que ledit bras étant tubulaire et contenant un train d'engrenages pour l'entraînement de la roue, sa première extrémité est fixée par l'intermédiaire d'un roulement sur le carter d'une boîte de transmission, cette boîte de transmission et le bras de suspension constituant un ensemble modulaire fixé par exemple par vissage sur la caisse du véhicule. It therefore proposes a wheel suspension of the pulled arm type for a motor vehicle, comprising a suspension arm of which a first end is mounted on the body of the vehicle and of which a second end is carried by the hub of a wheel, characterized in that that said arm being tubular and containing a gear train for driving the wheel, its first end is fixed by means of a bearing on the casing of a gearbox, this gearbox and the arm suspension constituting a modular assembly fixed for example by screwing on the vehicle body.
Avantageusement, cet ensemble modulaire est fixé à la caisse du véhicule par l'intermédiaire de la bague extérieure du roulement précité. Advantageously, this modular assembly is fixed to the vehicle body by means of the outer ring of the aforementioned bearing.
Selon une autre caractéristique de l'invention, la bague extérieure du roulement est fixée par vissage sur le bord d'un orifice circulaire de la caisse, cet orifice ayant un diamètre interne supérieur aux dimensions correspondantes de la boîte de transmission. According to another characteristic of the invention, the outer ring of the bearing is fixed by screwing on the edge of a circular orifice of the body, this orifice having an internal diameter greater than the corresponding dimensions of the gearbox.
Selon encore une autre caractéristique de l'invention, la seconde extrémité du bras précité porte un mécanisme réducteur destiné à être monté dans le moyeu de la roue pour l'entraînement de celle-ci en rotation. According to yet another characteristic of the invention, the second end of the aforementioned arm carries a reduction mechanism intended to be mounted in the hub of the wheel for driving the latter in rotation.
Avantageusement, le bras de suspens ion, la boîte de transmission et le mécanisme réducteur comprennent chacun un axe de symétrie, permettant leur utilisation du côté gauche et du côté droit du véhicule. Advantageously, the suspension arm, the gearbox and the reduction mechanism each comprise an axis of symmetry, allowing their use on the left and right side of the vehicle.
L'invention permet, de façon générale, une simplification notable de l'assemblage d'une suspension d'une roue arrière motrice d'un véhicule, cet assemblage pouvant être réalisé en atelier sur un établi et consistant à assembler entre elles des pièces de dimensions relativement faibles. L'ensemble modulaire ainsi réalisé peut ensuite être monté de façon simple, par exemple par vissage, sur la caisse d'un véhicule automobile. The invention allows, in general, a significant simplification of the assembly of a suspension of a driving rear wheel of a vehicle, this assembly being able to be carried out in the workshop on a workbench and consisting in assembling parts of them relatively small dimensions. The modular assembly thus produced can then be mounted in a simple manner, for example by screwing, on the body of a motor vehicle.
La modularité de cet ensemble simplifie la fabrication, le montage et la maintenance et réduit leurs coûts. The modularity of this set simplifies manufacturing, assembly and maintenance and reduces their costs.
L'invention sera mieux comprise et d'autres caractéristiques, détails et avantages de celle-ci appa raitront plus clairement à la lecture de la description qui suit, faite à titre d'exemple en référence au dessin annexé dans lequel la figure unique est une vue schématique en coupe partielle d'une suspension selon l'invention. The invention will be better understood and other characteristics, details and advantages thereof will appear more clearly on reading the description which follows, given by way of example with reference to the appended drawing in which the single figure is a schematic view in partial section of a suspension according to the invention.
Dans l'exemple représenté au dessin, la référence 10 désigne la caisse d'un véhicule automobile, par exemple un véhicule blindé léger, qui comprend des roues arrière motrices portant la caisse 10 par l'intermédiaire de suspensions du type à bras tiré. In the example shown in the drawing, the reference 10 designates the body of a motor vehicle, for example a light armored vehicle, which comprises rear-wheel drive carrying the body 10 by means of suspensions of the arm type.
Chaque roue arrière motrice est ainsi reliée à la caisse 10 par un bras de suspension 12 dont une pre mière extrémité 14 est fixée par l'intermédiaire d'un roulement 16 sur la caisse 10 du véhicule, et dont l'autre extrémité 18 porte un mécanisme réducteur 20 destiné à être logé dans le moyeu de la roue pour entraîner celle-ci en rotation autour de son axe 22. Each rear drive wheel is thus connected to the body 10 by a suspension arm 12, a first end 14 of which is fixed by means of a bearing 16 on the body 10 of the vehicle, and the other end of which carries a reduction mechanism 20 intended to be housed in the hub of the wheel in order to drive the latter in rotation about its axis 22.
Le bras 12 est tubulaire et contient un train d'engrenages qui assure la transmission d'un couple moteur au mécanisme réducteur 20, ce train d'engrenages étant lui-même en prise avec les engrenages d'une boîte de transmission ou de liaison 24 dont une entrée 26 re çoit un arbre moteur entraîné par les moyens de propulsion du véhicule. The arm 12 is tubular and contains a gear train which ensures the transmission of a driving torque to the reduction mechanism 20, this gear train itself being engaged with the gears of a transmission or linkage box 24 an input 26 of which receives a motor shaft driven by the vehicle's propulsion means.
La boîte de transmission 24 est également fixée à la caisse 10 du véhicule par l'intermédiaire du roulement 16. The gearbox 24 is also fixed to the body 10 of the vehicle by means of the bearing 16.
De façon plus précise, ce roulement 16, qui est du type à rouleaux croisés dans l'exemple représenté au dessin, comprend une bague intérieure 28 sur la face extérieure de laquelle est fixée la première extrémité 14 du bras 12, et une bague extérieure 30 sur laquelle est fixé le carter de la boîte de transmission 24 du côté opposé au bras 12, cette bague 30 étant elle-même fixée sur le bord d'un orifice circulaire 32 de la caisse 10. Cet orifice circulaire a un diamètre interne qui est supé rieur aux dimensions correspondantes de la boîte de transmission 24 et qui est inférieur au diamètre extérieur maximal du roulement 16. More specifically, this bearing 16, which is of the crossed roller type in the example shown in the drawing, comprises an inner ring 28 on the outer face of which the first end 14 of the arm 12 is fixed, and an outer ring 30 on which is fixed the casing of the transmission box 24 on the side opposite to the arm 12, this ring 30 being itself fixed on the edge of a circular orifice 32 of the body 10. This circular orifice has an internal diameter which is greater than the corresponding dimensions of the gearbox 24 and which is less than the maximum outside diameter of the bearing 16.
Les fixations de l'extrémité 14 du bras 12 et de la boîte de transmission 24 sur les bagues 28 et 30 du roulement et la fixation du roulement sur la caisse 10 sont réalisées au moyen d'une pluralité de vis que l'on a représenté schématiquement par des traits d'axe. The attachments of the end 14 of the arm 12 and of the transmission box 24 on the rings 28 and 30 of the bearing and the attachment of the bearing on the body 10 are made by means of a plurality of screws which have been shown. schematically by axis lines.
De façon classique, le bras de suspension 12 comporte également des moyens 34, tels qu'une ou plusieurs chapes d'articulation de l'extrémité d'un vérin ou moyen analogue dont une autre extrémité est articulée sur la caisse 10 du véhicule. Le bras 12 peut également comprendre, du côté de son autre extrémité 18, une patte non représentée formant butée. Conventionally, the suspension arm 12 also includes means 34, such as one or more hinges of articulation of the end of a jack or similar means, another end of which is articulated on the body 10 of the vehicle. The arm 12 can also include, on the side of its other end 18, a tab, not shown, forming a stop.
On comprend que le bras 12, le mécanisme réducteur 20, le roulement 16 et la boîte de transmission 24 peuvent être assemblés les uns aux autres à distance de la caisse 10 du véhicule, cet assemblage étant facilité du fait des dimensions relativement peu importantes des pièces à assembler. It is understood that the arm 12, the reduction mechanism 20, the bearing 16 and the transmission box 24 can be assembled to each other at a distance from the body 10 of the vehicle, this assembly being facilitated due to the relatively small dimensions of the parts. to assemble.
L'ensemble constitué par le bras 12, le mécanisme réducteur 20, le roulement 16 et la boîte de transmission 24 peut ensuite être approché de la caisse 10 du véhicule, puis la boîte de transmission 24 est amenée à l'intérieur de la caisse par passage à travers l'orifice 32 de celle-ci, et l'ensemble est fixé à la caisse par vissage de la bague extérieure 30 du roulement sur la face extérieure de la caisse 10. The assembly constituted by the arm 12, the reduction mechanism 20, the bearing 16 and the gearbox 24 can then be approached from the body of the vehicle, then the gearbox 24 is brought inside the body by passage through the orifice 32 thereof, and the assembly is fixed to the body by screwing the outer ring 30 of the bearing onto the outer face of the body 10.
On notera que, selon l'invention, seules les fixations du bras 12 et de la boîte 24 sur la roulement 16 doivent être étanches alors que, dans la technique antérieure, le bras 12 devait être monté de façon étanche sur le roulement 16, le roulement 16 devait être monté de façon étanche sur la caisse 10 du véhicule et la bote de transmission 24 devait également être montée de façon étanche sur la caisse 10. It will be noted that, according to the invention, only the fastenings of the arm 12 and of the box 24 on the bearing 16 must be sealed whereas, in the prior art, the arm 12 had to be mounted in a sealed manner on the bearing 16, the bearing 16 had to be tightly mounted on the body 10 of the vehicle and the transmission box 24 also had to be tightly mounted on the body 10.
Par ailleurs, la modularité de l'ensemble constitué par le bras 12 , le mécanisme réducteur 20 et la boîte de transmission 24 est améliorée par le fait que chacun de ces éléments comporte un axe de symétrie, ce qui permet d'utiliser l'ensemble ainsi assemblé aussi bien du côté gauche que du côté droit du véhicule. Furthermore, the modularity of the assembly constituted by the arm 12, the reduction mechanism 20 and the transmission box 24 is improved by the fact that each of these elements comprises an axis of symmetry, which makes it possible to use the assembly thus assembled both on the left side and on the right side of the vehicle.
