Description

  

      Remorque    à longerons     métalliques.       Dans les remorques à longerons métal  liques, il est de toute importance de dimi  nuer le plus possible le poids mort du véhi  cule. Lorsqu'on calcule les profils employés  juste     suffisants    pour la charge utile, ils ne  sont pas assez hauts pour amener le fond  de la benne à une     hauteur    de chargement  normale. Cet inconvénient est encore accen  tué lorsqu'on emploie dans le fond de la  benne des profils métalliques de résistance  spéciale. La hauteur de chargement étant  plus ou moins standardisée, on en est venu  à augmenter sans nécessité mécanique la  hauteur des profils employés, ce qui conduit  nécessairement à une augmentation indési  rable du poids mort de la remorque.  



  L'objet de la présente invention est une  remorque à longerons métalliques, dans la  quelle le problème de la légèreté de la benne  a été résolu en adaptant des traverses mé  talliques reliées     âuxdits    longerons par des  supports- consoles métalliques qui élèvent le  fond de la benne tout en diminuant la lon  gueur libre     desdites    traverses. Ces     dernières       sont calculées telles qu'elles     offrent    exacte  ment la sécurité nécessaire à la charge nor  male; par contre, c'est le moment de ré  sistance des longerons métalliques qui est  complètement mis à contribution.  



  Il est montré au dessin annexé un exemple  d'exécution d'une remorque selon la présente  invention.  



  La     fig.    1 est une coupe au travers de la  benne;  Les     fig.    2 et 3 représentent des détails  de la remorque et  Les     fig.    4 et 5 montrent la fixation de la  béquille télescopique à la remorque.  



  Cette remorque n'est représentée que pour  autant que la compréhension de l'invention  l'exige.  



  Sur les longerons a, qui sont reliés aux  essieux par des ressorts non représentés, sont  placés des supports-consoles b, qui s'emboî  tent dans le profil du longeron et qui s'éva  sent sur les côtés et forment des consoles  sur lesquelles la traverse e de la benne est  fixée. Cette dernière est métallique, d'un      profil en I et sa section est calculée de  manière que le moment de résistance à la  section dangereuse     xx    soit juste suffisant à  la charge utile. Ce moment peut être con  sidérablement réduit du fait que la longueur  libre y des traverses est considérablement  réduite.  



  De préférence, ces     supports-consoles    se  feront en un métal léger. On obtiendra de  cette manière pour un minimum de poids  mort un maximum de charge utile. .  



  Les longerons a se réunissent vers l'avant  de la remorque pour enserrer le crochet d.  Avant leur rencontre, ils sont reliés par la  traverse e, dans laquelle est montée une bé  quille télescopique f qui est représentée plus  spécialement en     fig.    3. Elle est formée de  deux tubes<I>f 1</I> et<B>f2,</B> qui sont angulaires, ce  qui permet de faire voyager le tube f 2 à  l'intérieur du tube f     l    au moyen de la vis     g     sans être dans l'obligation de pratiquer dans    ledit tube     f    1 une rainure de clavetage exi  geant une épaisseur de parois inutile ailleurs.  Cette disposition permet également de dimi  nuer le poids mort de la remorque, sans en  diminuer la résistance mécanique.



      Trailer with metal beams. In trailers with metal side members, it is of the utmost importance to reduce the dead weight of the vehicle as much as possible. When calculating the profiles used just sufficient for the payload, they are not high enough to bring the bottom of the body to a normal loading height. This drawback is further accentuated when metal profiles of special strength are employed in the bottom of the body. The loading height being more or less standardized, we have come to increase without mechanical necessity the height of the profiles used, which necessarily leads to an undesirable increase in the dead weight of the trailer.



  The object of the present invention is a trailer with metal side members, in which the problem of the lightness of the body has been solved by adapting metal cross members connected to said side members by metal brackets which raise the bottom of the body. while reducing the free lon gueur of said ties. These are calculated in such a way that they offer the exact safety necessary for normal load; on the other hand, it is the moment of resistance of the metal spars which is completely involved.



  An exemplary embodiment of a trailer according to the present invention is shown in the accompanying drawing.



  Fig. 1 is a section through the bucket; Figs. 2 and 3 show details of the trailer and Figs. 4 and 5 show the attachment of the telescopic stand to the trailer.



  This trailer is shown only insofar as the understanding of the invention requires it.



  On the side members a, which are connected to the axles by springs not shown, are placed brackets b, which fit into the profile of the side member and which open out on the sides and form consoles on which the cross member of the bucket is fixed. The latter is metallic, with an I-profile and its section is calculated so that the moment of resistance to the dangerous section xx is just sufficient for the payload. This moment can be considerably reduced because the free length y of the sleepers is considerably reduced.



  Preferably, these console supports will be made of a light metal. In this way, a maximum payload will be obtained for a minimum of dead weight. .



  The side members a meet towards the front of the trailer to grip the hook d. Before they meet, they are connected by the cross member e, in which is mounted a telescopic keel f which is shown more specifically in FIG. 3. It is formed by two tubes <I> f 1 </I> and <B> f2, </B> which are angular, which allows the tube f 2 to travel inside the tube fl by means of of the screw g without being obliged to make in said tube f 1 a keyway requiring unnecessary wall thickness elsewhere. This arrangement also makes it possible to reduce the dead weight of the trailer, without reducing its mechanical strength.
