Description

L'invention concerne un véhicule de manutention et de terrassement, prenant les charges en porte à faux par rapport à son essieu avant, par l'intermédiaire d'un bras de levage porte-outil, selon le préambule de la revendication 1. Il existe differentes façons connues, d'orienter en direction sur route les engins de manutention: Les plus courantes consistent soit en l'orientation de roues directrices montées sur fusée à axe vertical à la façon des véhicules automobile, soit en l'utilisation d'un chassis en deux éléments porteurs respectivement, des roues avant et des roues arrière; ces deux éléments étant liés entre eux par une articulation à axe vertical, l'orientation sur route est obtenue par le débattement relatif de ces éléments, avant et arrière, du chassis l'un par rapport à l'autre.The invention relates to a handling and earthmoving vehicle, taking loads cantilevered with respect to its front axle, by means of a tool-carrying lifting arm, according to the preamble of claim 1. There are various known ways of orienting handling equipment in the direction of the road: The most common consist either of orienting steered wheels mounted on a rocket with a vertical axis in the manner of motor vehicles, or of using a chassis in two bearing elements respectively, front wheels and rear wheels; these two elements being linked together by an articulation with a vertical axis, the road orientation is obtained by the relative movement of these elements, front and rear, of the chassis relative to one another.

Il est déjà connu des véhicules de manutention correspondant au préambule de la revendication (US-A-4 082 197). Ce document US-A-4 082 197 concerne un véhicule de manutention, dont le chassis est composé de deux éléments, porteurs respectivement de l'essieu avant et de l'essieu arrière, éléments articulés entre eux autour d'un axe charnière verticale. Ce véhicule comporte également un bras supérieur porteur, solidaire de l'élément arrière du chassis par un axe horizontal permettant à ce bras disposé longitudinalement et au dessus du chassis, d'élever ou d'abaisser la charge portée.Handling vehicles corresponding to the preamble of the claim (US-A-4,082,197) are already known. This document US-A-4,082,197 relates to a handling vehicle, the chassis of which is composed of two elements, carrying respectively the front axle and the rear axle, elements articulated together around a vertical hinge axis. This vehicle also comprises an upper carrying arm, integral with the rear element of the chassis by a horizontal axis allowing this arm disposed longitudinally and above the chassis, to raise or lower the load carried.

Dans ce type d'appareil l'articulation charnière verticale, liant les éléments avant et arrière du chassis, est mise à profit, par soulèvement de l'élément porteur du bras de levage au moyen de béquilles stabilisatrices, situées de part et d'autre des éléments du chassis, entre eux, afin de permettre au bras porteur de la charge de prendre ou déposer celle-ci, dans un secteur limité, situé de part et d'autre de l'axe longitudinal du véhicule. Cette forme de réalisation connue n'autorise cependant qu'une orientation latérale très limitée du bras porteur; limitée par le faible débattement permis par l'articulation charnière située entre les éléments avant et arrière du chassis, éléments qui, du fait de leur largeur propre, se gênent mutuellement dans ce débattement et en limitent ainsi l'importance.In this type of device, the vertical hinge joint, linking the front and rear elements of the chassis, is taken advantage of, by lifting the carrying element of the lifting arm by means of stabilizing crutches, located on either side. elements of the chassis, between them, in order to allow the load-carrying arm to pick up or deposit it, in a limited sector, situated on either side of the longitudinal axis of the vehicle. This known embodiment, however, allows only a very limited lateral orientation of the support arm; limited by the small clearance allowed by the hinge joint located between the front and rear elements of the chassis, elements which, due to their own width, interfere with each other in this clearance and thus limit their importance.

Il est également connu des dispositifs annexes, tels qu'exposés au document FR-A-383.409, qui, eux, ne font pas partie intégrante de l'engin, mais ce placent au-dessous de lui, pour, tout en améliorant sa stabilité en le surélevant, assurent sa rotation sur lui-même. Ce type de dispositif présente le gros inconvénient de devoir se placer au-dessous des véhicules porteurs d'équipement, et, par conséquent, de limiter leur garde au sol, nécessaire pour évoluer dans des terrains difficiles et boueux, dans lesquels de tels engins ne peuvent évoluer. La présente invention a pour but, d'une part, d'apporter une solution à ces difficultés, d'autre part, telle qu'elle est caractérisée dans les revendications, de résoudre le problème consistant à créer un véhicule de manutention et de terrassement, capable de permettre par une solution simple, non seulement la prise ou la pose de charges frontales, mais, également, et notemment par rapport au brevet USA. 4.082.197, la prise et la pose de charges situées tout autour de l'engin lui-même, sur un secteur de 360°, lorsque celui-ci travaille à poste fixe.There are also known additional devices, as exposed in document FR-A-383.409, which themselves do not form an integral part of the machine, but place it below it, for, while improving its stability by raising it, ensure its rotation on itself. This type of device has the major disadvantage of having to be placed under vehicles carrying equipment, and, consequently, of limiting their ground clearance, necessary to operate in difficult and muddy terrains, in which such vehicles do not can evolve. The present invention aims, on the one hand, to provide a solution to these difficulties, on the other hand, as characterized in the claims, to solve the problem of creating a handling and earthmoving vehicle , capable of enabling, by a simple solution, not only the taking or placing of frontal loads, but also, and notably in relation to the USA patent. 4,082,197, the taking and setting of loads located all around the machine itself, on a sector of 360 °, when the latter works at a fixed position.

A cet effect, l'invention consiste en un chassis en deux éléments, porteurs respectivement des roues avant et des roues arrière, dans lequel, tel que caractérisé dans les revendications, l'élément avant est porteur d'un pivot vertical, et d'un chassis stabilisateur, constituant, lorsqu'il est abaissé au sol, un surélévateur du véhicule dont les roues ne reposent plus au sol; cependant que l'élément arrière, constitué par une poutre pont, portant à l'avant un boitier de rotation recevant le pivot, peut tourner librement, autour, et au-dessus, de l'élément avant. Cet élément arrière étant également porteur du bras de levage recevant la charge, cette dernière, elle-même, peut donc être déposée, ou prise, par le bras, dans un secteur de 360° autour du stabilisateur reposant au sol.To this end, the invention consists of a frame in two elements, carrying respectively the front wheels and the rear wheels, in which, as characterized in the claims, the front element is carrying a vertical pivot, and a stabilizing frame, constituting, when lowered to the ground, a vehicle riser whose wheels no longer rest on the ground; however, the rear element, constituted by a bridge beam, carrying at the front a rotation box receiving the pivot, can rotate freely, around, and above, the front element. This rear element also carrying the lifting arm receiving the load, the latter itself can therefore be deposited, or taken, by the arm, in a sector of 360 ° around the stabilizer resting on the ground.

Une forme de réalisation d'un appareil réalisé suivant l'invention, est décrite sur les planches suivantes:

  • La figure 1 est une vue de profil du véhicule en coupe partielle longitudinale, en position route.
  • La figure 2, une vue de dessus de ce même véhicule.
  • La figure 3, est une vue de profil, en coupe partielle longitudinale, du véhicule, en position immobile stable, l'élément arrière pouvant tourner en rotation autour du pivot.
  • La figure 4, montre une forme de réalisation du dispositif d'orientation et de rotation.
An embodiment of an apparatus produced according to the invention is described on the following plates:
  • Figure 1 is a side view of the vehicle in partial longitudinal section, in the road position.
  • Figure 2, a top view of the same vehicle.
  • FIG. 3 is a side view, in partial longitudinal section, of the vehicle, in a stable stationary position, the rear element being able to rotate in rotation around the pivot.
  • Figure 4 shows an embodiment of the orientation and rotation device.

Comme il est représenté figure 1, le véhicule est composé d'une boîte de vitesse (1), sur laquelle se greffent les éléments importants de l'ensemble de l'appareil, et, particulièrement, le moteur (2) qui lui est accouplé, les roues motrices (3). Elle supporte également, par l'intermédiaire de bielles (4a) articulées directement sur les fusées porteuses (1 a) (figure 2) de la boîte de vitesse (1), et (4b), un stabilisateur (4), dont l'abaissement est commandé par les vérins (4c).As shown in Figure 1, the vehicle is composed of a gearbox (1), on which are grafted the important elements of the entire device, and, in particular, the motor (2) which is coupled to it , the driving wheels (3). It also supports, by means of connecting rods (4a) articulated directly on the carrier rockets (1a) (figure 2) of the gearbox (1), and (4b), a stabilizer (4), the lowering is controlled by the cylinders (4c).

A la partie superieure de cette boîte, un pivot (5) reçoit l'élément arrière du chassis. Cet élément arrière est composé d'une simple poutre-pont (6), recevant: à l'avant, un boîtier de rotation (7), et, à l'arrière, un ensemble de deux goussets (8), assurant, à la fois, le support de l'essieu arrière (9) du véhicule, l'articulation arrière du bras de levage (15) par son axe horizontal (10), et l'articulation (11b) du vérin de levage ( 1 1At the upper part of this box, a pivot (5) receives the rear element of the chassis. This rear element is composed of a simple girder-bridge (6), receiving: at the front, a rotation box (7), and, at the rear, a set of two gussets (8), ensuring, at at the same time, the rear axle support (9) of the vehicle, the articulation rear of the lifting arm (15) by its horizontal axis (10), and the articulation (11b) of the lifting cylinder (1 1

Un mode de réalisation de la commande d'orientation et de rotation, est donné figure 4, dans laquelle un moteur hydraulique (12), solidaire du boîtier (7), entraînant un pignon denté (13), engrène avec une couronne dentée (14), solidaire du pivot (5), donc de la boîte de vitesse (1).An embodiment of the orientation and rotation control is given in FIG. 4, in which a hydraulic motor (12), integral with the housing (7), driving a toothed pinion (13), meshes with a toothed crown (14 ), integral with the pivot (5), therefore with the gearbox (1).

Ainsi, sur route, le stabilisateur (4) relevé, suivant figure 1, l'orientation en direction est assurée autour du pivot (5), l'essieu avant moteur, et ses roues (3), et l'essieu arrière (9), et ses roues (3a) reposant au sol. En position véhicule immobilisé, Planche 2 figure 1, les bielles (4a), tournant autour de l'axe des fusées (1 a) de la boîte de vitesse (1), sous la poussée des vérins (4c), entraînent les bielles (4b), et abaissent au sol le stabilisateur (4), soulevant ainsi du sol les roues avant (3), l'ensemble boîte (1), et, par suite, l'arrière (9) du chassis (6) et ses roues arrière (3a) qui, ainsi, ne portent plus au sol, permettant la rotation, autour du pivot (5), de l'ensemble arrière porteur du bras (15) et de son godet (16). Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation ci- dessus décrit et représenté, à partir duquel on pourra, au besoin, recourir à d'autres modes et d'autres formes de réalisation, sans pour cela sortir du cadre de l'invention tel que définie par les revendications.Thus, on the road, the stabilizer (4) raised, according to FIG. 1, the directional orientation is ensured around the pivot (5), the driving front axle, and its wheels (3), and the rear axle (9 ), and its wheels (3a) resting on the ground. In the stationary vehicle position, Plate 2 in Figure 1, the connecting rods (4a), rotating around the spindle axis (1a) of the gearbox (1), under the thrust of the jacks (4c), drive the connecting rods ( 4b), and lower the stabilizer (4) to the ground, thereby lifting the front wheels (3), the gearbox assembly (1), and, consequently, the rear (9) of the chassis (6) and its rear wheels (3a) which, thus, no longer bear on the ground, allowing rotation, around the pivot (5), of the rear carrier assembly of the arm (15) and of its bucket (16). Of course, the invention is not limited to the embodiment described above and shown, from which one can, if necessary, use other modes and other embodiments, without this. depart from the scope of the invention as defined by the claims.
