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.
