Description

  

  Dispositif de soulèvement, notamment de benne basculante    L'invention a pour objet un dispositif de sou  lèvement, notamment de benne basculante.  



  Le but de l'invention a été de réaliser un dispo  sitif permettant une très grande amplitude de levage  sans avoir recours à un vérin à expansions multiples.  



  Le dispositif de soulèvement, notamment de  benne basculante, est caractérisé en ce qu'il comporte,  d'une part, deux bras respectivement articulés par  l'une de leurs extrémités sur chacun des éléments  dont il convient d'assurer le déplacement relatif et,  par l'autre, sur chacune des extrémités d'une paire de  bielles de liaison et, d'autre part, un vérin télesco  pique articulé sur les bras en un point intermédiaire  de leur longueur.  



  L'invention sera mieux comprise à la lecture de  la description qui va suivre et à l'examen des dessins  annexés dans lesquels  Les fia. 1 et 2 représentent, avec arrachement  partiel, une benne basculante équipée d'un dispositif  respectivement en position de route et en position  de     basculement,    et  la     fig.    3 est une perspective du dispositif en  position d'expansion partielle, le châssis de la benne  n'étant pas représenté en vue d'une meilleure com  préhension du dessin.  



  Sur les figures, le camion comporte un châssis C  portant à l'arrière des paliers 1 sur lesquels le faux  châssis basculant F de la benne B est articulé autour  d'un axe a.  



  Sur le châssis C et dans une région située, de  préférence, en avant du centre de charge de la benne,  est fixée une chape 2 dans laquelle l'extrémité du  bras inférieur 3 est articulée autour d'un axe     b.    De    la même manière, le bras supérieur 4 est articulé  autour d'un axe d dans une chape 5 solidaire du  faux châssis basculant F.  



  Chacun des bras 3, 4 est constitué par deux       flasques        3a,        3b,        4a,   <I>4b</I> entre lesquels les extrémités       7a,        7b,    respectivement du corps et de la tige de  piston du vérin hydraulique 7, sont articulées autour  des axes     f,    g.         Les    bras 3, 4 sont     reliés    entre eux par la paire  de bielles     6,,,   <B>61,</B>     articulées    sur les bras autour des  axes e,<I>e'.</I>  



  Il est à remarquer que les axes     f,    g sont décalés  à l'opposé du vérin par rapport à l'alignement des       articulations    e, d d'une part et     b,    é d'autre part.  



  Le vérin 7 est évidemment relié à une pompe de  façon connue, par des canalisations souples assurant  l'arrivée de l'évacuation du liquide sous pression.  Ces     dispositifs,    bien connus dans la pratique, n'ont  pas été représentés sur les     figures.     



  Les éléments du dispositif sont aménagés et  dimensionnés de telle sorte qu'en position de repos  de la benne     (fig.    1) les axes<I>b</I> et<I>d</I> soient sensible  ment à l'aplomb l'un de l'autre, les bras s'étendant  de façon sensiblement horizontale, de part et d'autre  de ces axes, c'est-à-dire vers l'avant pour le bras 4  et vers l'arrière pour le bras 3.  



  La     fig.    1 montre que dans     cette    position le vérin  à simple expansion 7, malgré sa longueur relative  ment grande, se loge très facilement entre la benne et  le châssis dans une position voisine de l'horizontale.  



  Lorsque la pression du liquide est     appliquée    à  ce vérin, la tige     7b    du piston se développe, déter  minant ainsi le pivotement des bras 3, 4 autour des      articulations e, é par lesquelles chacun d'eux est  articulé sur les extrémités des bielles     6d,        6b.     



  L'ensemble du dispositif se déploie alors symé  triquement par rapport aux bielles, ainsi qu'il est  représenté aux     fig.    2 et 3.  



  Le dispositif ci-dessus décrit permet, par le choix  judicieux des rapports des bras de levier entre les  trois points d'application,     c'est-à-dire    les trois axes  de chaque bielle, de parvenir, ainsi que     l'illustre    la       fig.    2, à un très     grand    coefficient de multiplication  de la course de l'élément d'expansion du vérin. Cette  particularité     permet    de repousser nettement en avant  du centre de charge de la benne l'articulation d et,  par conséquent, l'articulation b. Cette disposition  est particulièrement intéressante en ce qu'elle permet  d'alléger le châssis qui ne supporte plus, au point  d'application du poids de la benne, qu'un effort  limité.  



  L'on pourrait, par exemple, utiliser le dispositif  dans une benne basculante aménagée par ailleurs de  façon bien connue de manière à basculer, soit sur  l'arrière, soit sur l'un ou l'autre des côtés latéraux  du véhicule.



  Lifting device, in particular for a tipping body The object of the invention is a lifting device, in particular for a tipping body.



  The object of the invention has been to provide a device allowing a very large amplitude of lifting without having to resort to a multiple expansion jack.



  The lifting device, in particular a tipping bucket, is characterized in that it comprises, on the one hand, two arms respectively articulated by one of their ends on each of the elements whose relative displacement should be ensured and, by the other, on each of the ends of a pair of connecting rods and, on the other hand, a telescopic jack articulated on the arms at an intermediate point of their length.



  The invention will be better understood on reading the description which follows and on examining the appended drawings in which the fia. 1 and 2 show, partially broken away, a tipping body equipped with a device in the road position and in the tilting position, respectively, and FIG. 3 is a perspective of the device in the partially expanded position, the chassis of the bucket not being shown for a better understanding of the drawing.



  In the figures, the truck comprises a frame C carrying at the rear of the bearings 1 on which the tilting subframe F of the bucket B is articulated about an axis a.



  On the frame C and in a region preferably located in front of the load center of the bucket, is fixed a yoke 2 in which the end of the lower arm 3 is articulated about an axis b. Likewise, the upper arm 4 is articulated around an axis d in a yoke 5 secured to the tilting subframe F.



  Each of the arms 3, 4 is made up of two flanges 3a, 3b, 4a, <I> 4b </I> between which the ends 7a, 7b, respectively of the body and of the piston rod of the hydraulic cylinder 7, are articulated around axes f, g. The arms 3, 4 are interconnected by the pair of connecting rods 6 ,,, <B> 61, </B> articulated on the arms around the axes e, <I> e '. </I>



  It should be noted that the axes f, g are offset away from the jack relative to the alignment of the joints e, d on the one hand and b, é on the other hand.



  The cylinder 7 is obviously connected to a pump in a known manner, by flexible pipes ensuring the arrival of the discharge of the pressurized liquid. These devices, well known in the art, have not been shown in the figures.



  The elements of the device are arranged and dimensioned in such a way that in the rest position of the bucket (fig. 1) the axes <I> b </I> and <I> d </I> are sensitive to the plumb with one another, the arms extending substantially horizontally, on either side of these axes, that is to say forwards for the arm 4 and rearwards for arm 3.



  Fig. 1 shows that in this position the single-expansion cylinder 7, despite its relatively large length, fits very easily between the bucket and the frame in a position close to the horizontal.



  When the pressure of the liquid is applied to this cylinder, the piston rod 7b expands, thus determining the pivoting of the arms 3, 4 around the joints e, by which each of them is articulated on the ends of the connecting rods 6d, 6b.



  The entire device is then deployed symmetrically with respect to the connecting rods, as shown in FIGS. 2 and 3.



  The device described above makes it possible, by the judicious choice of the ratios of the lever arms between the three points of application, that is to say the three axes of each rod, to achieve, as illustrated in FIG. . 2, to a very large multiplication coefficient of the stroke of the expansion element of the cylinder. This feature allows the articulation d and, consequently, the articulation b, to be pushed back clearly in front of the load center of the bucket. This arrangement is particularly advantageous in that it makes it possible to lighten the frame which no longer supports, at the point of application of the weight of the bucket, a limited force.



  One could, for example, use the device in a tipping body otherwise fitted in a well-known manner so as to tilt, either to the rear or to one or the other of the lateral sides of the vehicle.
