Abstract

The chassis longeron for a caravan has, on its lower side, a recess (3,3') onto which is fixed a horizontal flange (5), to retain the axle. The flange has a vertical plate (4) with a height equal to the thickness of the longeron, and welded to it. The longeron can be in two sections formed of a pressed sheet (1,1'), each having half of the recess, which abut and are spot welded to the vertical plate on the axle flange. The recess around the axle increases the ground clearance of the body to allow passage of cables or brake lines.

Description

La présente invention est relative à un longeron de châssis destiné,notamment,aux remorques dites caravanes. The present invention relates to a chassis beam intended, in particular, for trailers known as caravans.

Elle vise principalement la réalisation d'un longeron plus léger mais aussi résistant que ceux usuels et présentant une faible garde au sol,celle-ci étant nécessaire pour assurer une bonne stabilité et une résistance minimale à l'avancement de la caravane ainsi que pour faciliter son accès. Its main aim is to produce a beam that is lighter but as resistant as the usual ones and has low ground clearance, which is necessary to ensure good stability and minimal resistance to the advancement of the caravan as well as to facilitate its access.

Selon un mode de réalisation, chaque longeron,réalisé en tôle pliée par exemple,présente, à l'endroit de passage de l'essieu et à sa partie inférieure,une échancrure recevant une éclisse, en tôle plus épaisse que celle du longeron, fixée contre l'aile verticale dudit longeron. According to one embodiment, each spar, made of folded sheet metal for example, has, at the point of passage of the axle and at its lower part, a notch receiving a splint, made of sheet thicker than that of the spar, fixed against the vertical wing of said spar.

L'éclisse est pliée en équerre à sa partie inférieure de façon à former une aile horizontale,s'étendant à la hauteur du bord supérieur de l'échancrure précitée c'est-à-dire bien audessus du bord inférieur du longeron ,sous laquelle on fixe,à l'aide de boulons, la bride usuelle de 1'essieu.  The splint is folded square at its lower part so as to form a horizontal wing, extending to the height of the upper edge of the aforementioned notch, that is to say well above the lower edge of the spar, under which the usual axle flange is fixed with bolts.

Préférablement, l'essieu est réalisé en deux parties aboutées solidarisées par l'éclisse précitée,le tout étant soudé par points. Preferably, the axle is produced in two abutting parts joined together by the aforementioned splint, the whole being spot welded.

D'autres caractéristiques appraitront mieux dans la description qui va suivre et en se référant au dessin annexé à titre d'exemple,uniquement ;indicatif, dans lequel
Les figures 1 et 2 sont des vues en perspective d'un côté et de l'autre de la partie intéressée du longeron
La figure 3 en est une vue en perspective éclatée
La figure 4 est une coupe effectuée par IV-IV de la figure 1;
La figure 5 est une vue de côté, à plus petite échelle montrant la fixation d'un essieu sous l'aile horizontale de l'éclisse.
Other characteristics will appear better in the description which follows and with reference to the attached drawing by way of example, only; indicative, in which
Figures 1 and 2 are perspective views from one side and the other of the interested part of the spar
Figure 3 is an exploded perspective view
Figure 4 is a section through IV-IV of Figure 1;
Figure 5 is a side view, on a smaller scale showing the fixing of an axle under the horizontal wing of the splint.

En se reportant au dessin, on voit que les deux parties 1-1' du longeron , réalisées en tôle pliée de 2m/m d'épaisseur par exemple, sont aboutées par leurs extrémités 2-2' échancrées en 3-3' à leur partie inférieure. Referring to the drawing, we see that the two parts 1-1 'of the spar, made of folded sheet metal 2m / m thick for example, are butted by their ends 2-2' cut into 3-3 'at their lower part.

Les deux parties 1-1' sont solidarisées par une éclisse 4,convenablement pliée en U pour former une nervure de raidissement, réalisée en tôle pliée de 2,5m/m d'épaisseur par exemple,présentant principalement à sa partie inférieure une aile 5 horizontale se plaçant sous le bord inférieur des échancrures 3-3' pour s'étendre du côté du longeron opposé à l'éclisse 4.  The two parts 1-1 'are joined by a splint 4, suitably folded in a U to form a stiffening rib, made of folded sheet metal 2.5m / m thick for example, mainly having at its lower part a wing 5 horizontal placed under the lower edge of the notches 3-3 'to extend on the side of the spar opposite the splint 4.

Les parties 1-1' et l'éclisse 4 sont solidarisées par soudure électrique par points. Parts 1-1 'and the splint 4 are joined by electric spot welding.

L'essieu usuel E est fixé sous l'aile 5 par sa bride B à l'aide de boulons C ( figure 5). The usual axle E is fixed under the wing 5 by its flange B using bolts C (Figure 5).

On voit nettement sur la figure 5 que l'échancrure des deux parties du longeron permet, d'une part, le surbaissement de celui-ci,donc la diminution de la garde au sol et, d'autre part, le libre passage du câble ou de la canalisation de frein (non représenté ). It is clearly seen in Figure 5 that the notch of the two parts of the beam allows, on the one hand, the lowering thereof, therefore the reduction of the ground clearance and, on the other hand, the free passage of the cable or the brake line (not shown).

Enfin, avec un tel mode de réalisation, chaque longeron est considérablement renforcé à l'endroit où la charge est maximale puisque son épaisseur est plus que doublée au dessus de l'essieu. Finally, with such an embodiment, each spar is considerably reinforced at the place where the load is maximum since its thickness is more than doubled above the axle.

Bien entendu, le mode de réalisation décrit et représenté s'étend aux longerons réalisés en une seule partie ainsi qu'à ceux obtenus par emboutissage. Of course, the embodiment described and shown extends to the side members made in a single part as well as those obtained by stamping.

Elle s'étend aussi aux châssis de tous véhicules tractés ou tracteurs.  It also extends to the chassis of all towed vehicles or tractors.
