Description

SYSTèME DR LIAISON D'ONT ROUE A UNR CAISSE DR VRHICULH AOMOBILB
L'invention concerne un système de liaison d'une roue à une caisse d'un véhicule automobile , en particulier d'une roue motrice et/ou orientable d'un véhicule blindé léger à usage militaire.DR SYSTEM ON WHEEL CONNECTION TO UNR CASE DR VRHICULH AOMOBILB
The invention relates to a system for connecting a wheel to a body of a motor vehicle, in particular a driving and / or steerable wheel of a light armored vehicle for military use.

Les roues motrices et orientables d'un tel véhicule sont reliées à la caisse du véhicule par des moyens de suspension, des moyens de direction et des moyens de transmission de puissance. La caisse du véhicule est en général du type mécano-soudé et la fixation de ces moyens de suspension, de direction et de transmission sur la caisse nécessite un usinage relativement important, et des réglages ou ajustages de ces moyens les uns par rapport aux autres avec une précision relativement élevée. Ces opérations d'usinage et de réglage sont souvent longues et délicates à effectuer et sont donc coûteuses. The drive and steerable wheels of such a vehicle are connected to the vehicle body by suspension means, steering means and power transmission means. The vehicle body is generally of the mechanically welded type and the fixing of these suspension, steering and transmission means to the body requires relatively significant machining, and adjustments or adjustments of these means with respect to each other with relatively high accuracy. These machining and adjustment operations are often long and delicate to perform and are therefore expensive.

L'invention a pour objet un système de liaison entre une roue et la caisse d'un véhicule automobile, qui permette d'éviter ou au moins de réduire ces inconvénients. The subject of the invention is a connection system between a wheel and the body of a motor vehicle, which makes it possible to avoid or at least reduce these drawbacks.

L'invention a encore pour objet un système de ce type, qui soit compatible avec une conception et une construction modulaires du véhicule. The invention also relates to a system of this type, which is compatible with a modular design and construction of the vehicle.

Elle propose donc un système de liaison d'une roue à une caisse d'un véhicule automobile, en particulier une roue motrice et/ou orientable, associée à des moyens de suspension, des moyens d'orientation et/ou des moyens d'entraînement en rotation, caractérisé en ce qu'il comprend une plaque rigide rapportée sur la caisse du véhicule et comprenant des moyens de support des moyens précités de suspension, d'orientation et/ou d'entraînement. It therefore proposes a system for connecting a wheel to a body of a motor vehicle, in particular a driving and / or steerable wheel, associated with suspension means, orientation means and / or drive means. in rotation, characterized in that it comprises a rigid plate attached to the vehicle body and comprising means for supporting the aforementioned means of suspension, orientation and / or drive.

Avantageusement, les moyens de suspension, d'orientation et/ou d'entraînement de la roue sont montés et ajustés sur cette plaque, avant que iton fixe la plaque sur la caisse du véhicule. Advantageously, the suspension, orientation and / or drive means of the wheel are mounted and adjusted on this plate, before iton fixes the plate on the vehicle body.

Il en résulte une plus grande précision, car les usinages et réglages nécessaires sont réalisés sur une plaque de dimension restreinte et non sur la caisse du véhicule. Cela permet notamment de supprimer certains réglages et de faciliter les autres. This results in greater precision, because the necessary machining and adjustments are carried out on a plate of limited size and not on the vehicle body. This allows in particular to delete certain settings and facilitate others.

Il en résulte également une plus grande commodité de montage, car la fixation des moyens de suspension, de direction et/ou d'entraînement sur la plaque se fait en atelier et sur établi et donc dans des conditions beaucoup plus favorables, après quoi il ne reste qu'à fixer cette plaque, par exemple par vissage, sur la caisse du véhicule. This also results in greater assembly convenience, since the fixing of the suspension, steering and / or drive means to the plate is done in the workshop and on the workbench and therefore in much more favorable conditions, after which it does not It remains only to fix this plate, for example by screwing, on the vehicle body.

L'invention sera mieux comprise et d'autres caractéristiques, détails et avantages de celle-ci apparaitront 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 de dessus d'un système 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 view schematic from above of a system according to the invention.

Dans l'exemple de réalisation représenté, la référence 10 désigne une plaque métallique rigide destinée à être fixée par tout moyen approprié et par exemple par vissage sur la caisse 12 d'un véhicule automobile, représentée en traits pointillés. In the embodiment shown, the reference 10 designates a rigid metal plate intended to be fixed by any suitable means and for example by screwing on the body 12 of a motor vehicle, shown in dotted lines.

Cette plaque 10 comporte, sur sa face extérieure 14, des moyens 16 d'articulation des moyens de support du moyeu 18 d'une roue représentée en pointillés, ces moyens 16 comprenant par exemple des chapes dans lesquelles sont engagés des bouts d'arbore 20 formés aux extrémités d'un triangle 22 de suspension dont le sommet est relié par une rotule 24 au moyeu 18 de la roue. Bien que seul le triangle supérieur de suspension 22 soit visible sur le dessin, un triangle inférieur du même type est monté de la même façon entre la plaque 10 et le moyeu 18. This plate 10 comprises, on its outer face 14, means 16 for articulation of the means for supporting the hub 18 of a wheel shown in dotted lines, these means 16 comprising, for example, yokes in which the ends of the arbor 20 formed at the ends of a suspension triangle 22, the top of which is connected by a ball joint 24 to the hub 18 of the wheel. Although only the upper suspension triangle 22 is visible in the drawing, a lower triangle of the same type is mounted in the same way between the plate 10 and the hub 18.

Le système de direction du véhicule, disposé à l'intérieur de la caisse 12, comprend des moyens 26 d'ac tionnement d'un levier de renvoi 28 monté pivotant autour d'un axe sensiblement vertical dans un orifice de la plaque 10, l'extrémité de ce levier de renvoi 28 opposée au moyen d'actionnement 26 étant reliée par une biellette 30 à une patte latérale 32 du moyeu 18 de la roue. The vehicle steering system, placed inside the body 12, comprises means 26 for actuating a return lever 28 mounted pivoting about a substantially vertical axis in an orifice in the plate 10, l end of this return lever 28 opposite the actuating means 26 being connected by a link 30 to a side tab 32 of the hub 18 of the wheel.

La plaque 10 supporte également une boîte de transmission 34, qui est fixée sur la face interne 36 de la plaque 10 par exemple par des pattes vissées et qui comporte un arbre de sortie 38 s'étendant à travers un orifice 40 de la plaque 10 pour être relié par des moyens 42 du type joint homo-cinétique ou joint à la Cardan au moyeu 18 de la roue ou à un mécanisme réducteur logé dans le moyeu 18. The plate 10 also supports a transmission box 34, which is fixed to the internal face 36 of the plate 10 for example by screwed lugs and which comprises an output shaft 38 extending through an orifice 40 in the plate 10 for be connected by means 42 of the homo-kinetic joint type or joined to the Cardan joint to the hub 18 of the wheel or to a reduction mechanism housed in the hub 18.

La boîte de transmission 34 contient un train d'engrenages assurant une transmission de couple moteur entre un arbre d'entrée 44 et l'arbre de sortie 38 relié au moyeu 18. The transmission box 34 contains a gear train ensuring transmission of engine torque between an input shaft 44 and the output shaft 38 connected to the hub 18.

Comme indiqué dans ce qui précède, il est beaucoup plus facile et plus commode de monter les triangles de suspension 22, le levier de renvoi 28 et la boîte de transmission 34 sur la plaque 10 que de les monter directement sur la caisse 12 du véhicule. Les usinages et réglages sont moins importants, certains réglages, tels que les ajustements des longueurs de cardan étant même supprimés. Lorsque le montage et le réglage des différents moyens de suspension, de direction et d'entraînement sur la plaque 10 ont été réalisés, il suffit de fixer la plaque 10 sur la caisse 12 du véhicule au moyen de vis réparties sur la périphérie de la plaque 10. As indicated in the foregoing, it is much easier and more convenient to mount the wishbones 22, the return lever 28 and the gearbox 34 on the plate 10 than to mount them directly on the body 12 of the vehicle. The machining and adjustments are less important, certain adjustments, such as the adjustments of the cardan lengths being even eliminated. When the mounting and adjustment of the various suspension, steering and drive means on the plate 10 have been carried out, it suffices to fix the plate 10 to the body 12 of the vehicle by means of screws distributed around the periphery of the plate 10.

Par ailleurs, la plaque 10 munie de ces moyens de suspension de direction et d'entraînement constitue un sous-ensemble qui s'intègre dans une conception et une construction modulaires du véhicule, cette modularité se traduisant par une diminution des coûts d'assemblage, d'approvisionnement et de maintenance.  In addition, the plate 10 provided with these steering and drive suspension means constitutes a sub-assembly which is integrated into a modular design and construction of the vehicle, this modularity resulting in a reduction in assembly costs, supply and maintenance.
