Abstract

The tilting trailer has a load platform (1) supported by wheels (2), on an axle (3). It has brakes (4) to lock the wheels and a drawbar (7). The platform pivots on the axle and the drawbar is fixed to it by a pivot (11) rear of, and below, the axle. When the brakes are applied, forward movement of the tractor tilts the platform to a discharge position. Rearwards movement of the tractor raises it again. A stabiliser (14) has an opening (15) in which slides a finger (16) on the drawbar. There are several platform fixings (17,19) to the drawbar.

Description

La présente invention a pour objet une remorque basculante, dont le mouvement de basculement dans le sens du déchargement est commandé par l'avance du véhicule tracteur, tandis que son relevage est provoqué par le recul du véhicule tracteur après que le déchargement ait été effectué. The present invention relates to a tilting trailer, the tilting movement in the unloading direction is controlled by the advance of the towing vehicle, while its lifting is caused by the backward movement of the towing vehicle after unloading has been carried out.

Les remorques connues de ce type comportent en général des mécanismes de commande relativement compliqués, qui comprennent notamment des systèmes à genouillères comprenant plusieurs biellettes et de nombreux axes d'articulations. Cette complexité est source de pannes fréquentes et rend conteuse la fabrication de ces remorques. Known trailers of this type generally have relatively complicated control mechanisms, which in particular include toggle joint systems comprising several links and numerous articulation axes. This complexity is a source of frequent breakdowns and makes the manufacture of these trailers untrue.

An contraire, l'invention se propose de réaliser une remorque basculante du type mentionné ci-dessus qui comprenne un mécanisme de commande simple, robuste et fiable et qui soit d'un prix de revient peu élevé. On the contrary, the invention proposes to produce a tilting trailer of the type mentioned above which comprises a simple, robust and reliable control mechanism and which is of a low cost price.

A cet effet, la remorque basculante selon l'invention qui, de manière connue comprend une plate-forme porte-charge ou caisse soutenue par une paire de roues montées folles sur un essieu, des freins permettant la solidarisation des roues avec 11 essieu et un tirant d'attelage à un véhicule tracteur, est caractérisé en ce que le tirant est fixé à la caisse au moyen d'au moins une articulation située à l'arrière et en dessous de l'axe de essieu. Ainsi, au moyen d'un mécanisme très simpleX les freins de la remorque étant actionnés, l'avance du véhicule tracteur en commande le déchargement tandis que le recul du véhicule tracteur en provoque le relevage. To this end, the tilting trailer according to the invention which, in known manner comprises a load-carrying platform or body supported by a pair of idler wheels mounted on an axle, brakes allowing the wheels to be secured with 11 axles and a tie rod to a towing vehicle, is characterized in that the tie rod is fixed to the body by means of at least one articulation situated at the rear and below the axle axis. Thus, by means of a very simple mechanism the brakes of the trailer being actuated, the advance of the towing vehicle controls the unloading while the retraction of the towing vehicle causes the lifting thereof.

Avantageusement, afin d'éviter une rotation intempestive et incontrôlée des roues durant l'opération de déchargement, l'essieu est solidaire d'un bras stabilisateur qui présente une lumière de guidage dans laquelle est engagé un doigt coulissant porté par le tirant d'attelage. Enfin, des moyens de fixation permettent de rendre la caisse solidaire du tirant d'attelage en position " route " dans laquelle la remorque est tirée par le véhicule tracteur. Advantageously, in order to avoid untimely and uncontrolled rotation of the wheels during the unloading operation, the axle is integral with a stabilizing arm which has a guide light in which is engaged a sliding finger carried by the drawbar . Finally, fixing means make it possible to make the body integral with the drawbar in the "road" position in which the trailer is pulled by the towing vehicle.

L'invention sera mieux comprise grâce à la description qui va maintenant être faite en se référant aux dessins annexés qui montrent un mode de réalisation préférentiel plais non limitatif d'une remorque selon l'invention. The invention will be better understood thanks to the description which will now be made with reference to the accompanying drawings which show a preferred non-limiting preferred embodiment of a trailer according to the invention.

Sur ces dessins,
ta figure 1 est une vue sch5matiue montrant la remorque de face, en position route,
ta figure 2 est analogue à la figurez, la remorque étant représentée en position de déchargement,
La figure 3 est une vue de dessus partielle de la remorque, certains éléments ayant été enlevés et d'autres coupés pour plus de clarté
ta remorque représentée sur les dessins comporte une plate-forme porte-charge, ou caisse 1 qui est soutenue par une paire de roues 2 reposant sur le sol S. tes roues 2 sont montées folles sur un essieu 3. Un mécanisme de commande 6 tel qu'un levier entrainant une roue à rochet permet de tendre des câbles 5 pour actionner des freins 4 afin de solidariser les roues 2 de l'essieu 3.Un tirant 7 permet d'atteler la remorque à un véhicule tracteur ( non représenté ) tel qu'une voiture de tourisme, de préférence au moyen d'une articulation multidirectionnelle ( rotule ).
In these drawings,
your FIG. 1 is a diagrammatic view showing the trailer from the front, in the road position,
your figure 2 is similar to the figure, the trailer being shown in the unloading position,
Figure 3 is a partial top view of the trailer, some parts having been removed and others cut for clarity
your trailer shown in the drawings comprises a load-carrying platform, or body 1 which is supported by a pair of wheels 2 resting on the ground S. your wheels 2 are mounted idly on an axle 3. A control mechanism 6 such that a lever driving a ratchet wheel makes it possible to tension cables 5 to actuate brakes 4 in order to secure the wheels 2 of the axle 3. A tie rod 7 makes it possible to couple the trailer to a towing vehicle (not shown) such than a passenger car, preferably by means of a multidirectional articulation (ball joint).

Sous la caisse 1, de chaque côté du plan de symétrie longitudinal X- de la remorque, est fixée une pièce 8 disposée verticalement. ta pièce 8 est constituée d'une pince 9 formant palier, montée à pivotement sur l'essieu 3 et d'une partie 10 formant console, dont le rôle sera expliqué plus loin. En vue de dessus le tirant 7 présente la forme d'un
U dont les branches 7a s'étendent vers l'arrière symétriquement par rapport au plan X-X. En vue de face chacune des branches 7a est coudée de manière appropriée, de sorte que son extrémité est fixée à la console 10 par une articulation 11 située en arrière et en dessous de l'axe de l'essieu 3.
Under the body 1, on each side of the longitudinal plane of symmetry X- of the trailer, is fixed a part 8 arranged vertically. your part 8 consists of a clamp 9 forming a bearing, pivotally mounted on the axle 3 and a part 10 forming a console, the role of which will be explained below. In top view the tie rod 7 has the shape of a
U whose branches 7a extend rearwards symmetrically with respect to the plane XX. In front view each of the branches 7a is bent appropriately, so that its end is fixed to the console 10 by a joint 11 located behind and below the axis of the axle 3.

ta partie 9 formant palier est immobilisée en translation sur l'essieu 3 par des manchon1x1és à celui-ci par soudage. T'essieu 3 est également solidaire de deux bras stabilisateurs 14 disposés symétriquement par rapport au plan médian X-X. Chacun des bras 14 est par exemple soudé d'un côté à l'essieu 3 et de l'autre au manchon 13. Chacun des bras 14 présente une ouverture allongée, ou lumière 15 dans laquelle est monté à coulissement un doigt 16 porté par la branche 7a associée. Ce doigt peut tout simplement être constitué par un boulon. La caisse 1 est pourvue, sur sa face avant d'une plaquette 17 percée d'un trou dans lequel, lorsque la caisse est mise en position horizontale, vient s'engager une tige filetée 18 fixée sur le dessus du tirant 7.Un écrou à oreilles 19 permet de bloquer la plaquette 17 sur la tige filetée 18 en rendant ainsi la caisse 1 solidaire du tirant 7.your part 9 forming a bearing is immobilized in translation on the axle 3 by sleeves1x1és thereto by welding. The axle 3 is also secured to two stabilizing arms 14 arranged symmetrically with respect to the median plane X-X. Each of the arms 14 is for example welded on one side to the axle 3 and on the other to the sleeve 13. Each of the arms 14 has an elongated opening, or lumen 15 in which a finger 16 carried by the associated branch 7a. This finger can simply be constituted by a bolt. The body 1 is provided, on its front face with a plate 17 pierced with a hole in which, when the body is brought into a horizontal position, engages a threaded rod 18 fixed on the top of the tie rod. A nut with lugs 19 makes it possible to block the plate 17 on the threaded rod 18 thereby making the body 1 integral with the tie rod 7.

La remorque fonctionne de la manière suivante:
En position " route 'L la caisse est solidarisée du tirant d'attelage 7 au moyen de l'écrou 19. les freins 4 sont desserrés et le véhicule tracteur peut tirer la remorque, les roues 2 tournant librement sur l'essieu 3. Pour vider la remorque de son contenu, le véhicule tracteur étant arrêté, l'opérateur actionne les freins 4 au moyen du mécanisme 6 et retire l'écrou 19. Ensuite il fait avancer doucement le véhicule tracteur, et corrélativement le tirant 7 ( flèche F, figure 2 ). les roues 2 étant bloquées, la traction opérée sur les consoles 10 par l'intermédiaire des articulations i1 provoque le basculement de la caisse 1 sur l'essieu 3, dans le sens du déchargement ( figure 2 ).Au cours de ce mouvement, malgré un léger débattement angulaire du bras 14, autorisé par la liberté de coulissement du doigt 16 dans la lumière 15, ce bras 14 maintient l'essieu 3 dans une position pratiquement fixe. Cette disposition permet d'empêcher un basculement incontrôlé de l'ensemble roues/essieu au cours du déchargement.
The trailer works as follows:
In the "road" position L the body is secured to the drawbar 7 by means of the nut 19. the brakes 4 are released and the tractor vehicle can pull the trailer, the wheels 2 turning freely on the axle 3. For empty the trailer of its contents, the towing vehicle being stopped, the operator applies the brakes 4 by means of the mechanism 6 and removes the nut 19. Then he gently advances the towing vehicle, and correspondingly the tie rod 7 (arrow F, the wheels 2 being locked, the traction operated on the consoles 10 by means of the joints i1 causes the body 1 to tip over on the axle 3, in the unloading direction (figure 2). this movement, in spite of a slight angular movement of the arm 14, authorized by the freedom of sliding of the finger 16 in the slot 15, this arm 14 maintains the axle 3 in a practically fixed position This arrangement makes it possible to prevent an uncontrolled tilting of wheel / axle combination unloading urs.

lorsque le contenu de la caisse a été vidé, l'opéra- teur fait reculer le véhicule tracteur, provoquant le recul des consoles 10 et le relevage de la caisse en position horizontale. Pour retrouver la position IL route"il suffit de desserrer les freins 4 et de remettre en place l'écrou à oreilles 19. when the contents of the body have been emptied, the operator causes the towing vehicle to reverse, causing the consoles 10 to retreat and the body to be raised to a horizontal position. To return to the IL road position "it is enough to release the brakes 4 and replace the wing nut 19.

On voit que le processus de déchargement- relevage qui vient d'être dédit est extrêmement simple, tout en utilisant un mécanisme de eo-zmarde également zimSle, robuste et peu eottet.  It can be seen that the unloading-lifting process which has just been removed is extremely simple, while using a mechanism of eo-zmarde also zimSle, robust and little eottet.

Il va de soi que l'invention ne se limite pas au dispositif qui a été décrit à simple titre d'exemple; elle en embrasse au contraire toutes les variantes. It goes without saying that the invention is not limited to the device which has been described simply by way of example; on the contrary, it embraces all its variants.

C'est ainsi qu'il serait possible de prévoir une commande du dispositif de verrouillage 17, 18, 19 et/ ou des freins 4 se faisant directement de l'intérieur du véhicule tracteur afin d'éviter à l'opérateur de devoir en descendre au cours de l'opération. A cet effet des systèmes de commande et de verrouillage hydrauliques ou électromécaniques pourraient être utilisés. Thus it would be possible to provide a control of the locking device 17, 18, 19 and / or the brakes 4 being made directly from the interior of the towing vehicle in order to avoid the operator having to get out of it. during the operation. To this end, hydraulic or electromechanical control and locking systems could be used.

Il est également possible d'interposer entre la caisse 1 et les roues 2 un dispositif de suspension élastique et d'amortissement. It is also possible to interpose between the body 1 and the wheels 2 an elastic suspension and damping device.

La remorque n'est pas obligatoirement indépendante du véhicule tracteur mais pourrait constituer avec celui-ci un ensemble intégral, du type camion-benne.  The trailer is not necessarily independent of the towing vehicle but could constitute with it an integral assembly, of the dump truck type.
