Abstract

The trailer allows retraction of the trailer wheels (R) during tilting of the trailer for improved stability. It has a slide fixed between the wheel bogie and the chassis to allow displacement of the axles in longitudinal directions under the control of hydraulic cylinders. Prior to tilting, the operator moves the axles to their maximum rearward position on the trailer. The slide moves on profiled rails via rollers. The two wheel axles can be can be placed in tandem.

Description

L'objet de l'invention concerne le transport de produits agricoles (céréales, tubercules, mais...) dans des bennes agricoles affectées à cet usage. The object of the invention relates to the transport of agricultural products (cereals, tubers, but ...) in agricultural skips assigned to this use.

Les exploitants ou entrepreneurs agricoles assurant le transport des produits agricoles utilisent des bennes appelées aussi remorques semi-portée. Par ailleurs l'utilisation d'un tracteur d'une puissance modeste (et donc d'un poids peu important sur l'essieu arrière) avec une benne de grande capacité (deux essieux) nécessite la présence d' système anti-cabrage. Le système anti-cabrage permet un report de charge de la remorque sur le tracteur. Ce système est généralement actionné pendant le bennage. Si ces bennes ne possèdent pas de système anti-cabrage, lors du bennage le risque d'avoir un cabrage (le châssis de la benne bascule en arrière) de la remorque est important. Les systèmes anti- cabrage développés par les constructeurs de matériels agricoles consistent à placer deux vérins hydraulique qui tendent éloigner le châssis de l'essieu arrière de la remorque. Farmers or agricultural contractors transporting agricultural products use skips also called semi-trailer trailers. In addition, the use of a tractor of modest power (and therefore of low weight on the rear axle) with a large capacity bucket (two axles) requires the presence of an anti-rearing system. The anti-tilt system allows load transfer from the trailer to the tractor. This system is generally activated during tipping. If these tippers do not have an anti-rearing system, during tipping the risk of having a rearing (the chassis of the tipper tilts back) of the trailer is important. The anti-tilt systems developed by agricultural equipment manufacturers consist of placing two hydraulic cylinders which tend to move the chassis away from the rear axle of the trailer.

L'invention permet un report de charge beaucoup plus efficace que le système traditionnel présenté précédemment. L'invention assure à la fois l'efficacité complète et la robustesse de l'appareillage dans les dures conditions d'emploi. The invention allows a much more efficient load transfer than the traditional system presented above. The invention ensures both the complete efficiency and the robustness of the apparatus under harsh conditions of use.

Selon des modes particulier de réalisation - Les essieux pourront être montées en bogie ou en tandem. Sur une remorque agricole équipé de deux essieux montées en bogie, ceux-ci peuvent pivoter, au dessus des axes des roues porteuses, autour d'un axe parallèle à ceux des roues et traversant un support réalisé en profilé du commerce. Ce support devra pouvoir coulisser sous le plateau long de deux glissières. L'articulation du bogie permettant au quatre roues de rester toujours en contact avec le sol. Il est facile de comprendre qu'a l'arrière des glissières le bogie maintiendra la moitié de la charge de la remorque (l'autre moitié sera supporté par le tracteur), et que ramené vers l'avant(au milieu de la benne), la remorque supportera toute la charge. According to particular embodiments - The axles can be mounted as a bogie or in tandem. On an agricultural trailer fitted with two axles mounted as a bogie, these can pivot, above the axes of the load wheels, around an axis parallel to those of the wheels and passing through a support made of commercial profile. This support must be able to slide under the long tray with two slides. The articulation of the bogie allowing the four wheels to always stay in contact with the ground. It is easy to understand that at the back of the slides the bogie will hold half of the trailer load (the other half will be supported by the tractor), and that brought forward (in the middle of the bucket) , the trailer will support the entire load.

Lorsque les essieux seront en position arrière maximum, le poids sur le tracteur sera important et la remorque pourra effectuer le bennage sans aucun incident. Après le bennage les essieux seront ramener en position initiale. Les vérins du type pression d'huile semblent les plus indiqués pour cette application. Pratiquement cette transformation d'une remorque est du ressort d'un mécanicien qualifié sans exiger une étude préalable et des calculs savants. When the axles are in maximum rear position, the weight on the tractor will be significant and the trailer will be able to dump without any incident. After tipping the axles will be brought back to the initial position. Oil pressure type cylinders seem to be the most suitable for this application. Practically this transformation of a trailer is the responsibility of a qualified mechanic without requiring a prior study and scholarly calculations.

Le dessin annexé illustre, à titre d'exemple, un mode de réalisation du dispositif conforme à la présente invention. La figure 1 montre le sens de mouvement de l'essieu qui permet d'effectuer un report de charge pour le bennage. La figure 2 représente l'invention. Sur ces figures (R) représente l'essieu arrière de la remorque. Les flèches montrent les déplacements des organes. La figure (3) représente le bogie(1) vu en agrandi de coté, et pourvu d'essieux sur lesquels sont assujetties les quatre roues (2). En (3) est articulé le bogie (1) sur un châssis (4) dont les longerons supportent des galets (5) pouvant rouler sur les glissières (6) fixées de chaque coté sous la caisse. Le verin à pression d'huile (V) sur la figure 2 a son cylindre à l'arrière du timon et son piston entraine la tige qui est attelé au bogie. Le fonctionnement du dispositif est fort simple :Lorsque le vérin amène les essieux vers l'arrière le bennage peut se réaliser en toute sécurité. Le chauffeur peut benner sa remorque. Enfin retour des essieux en position initiale. C'est ce qui se passe après le bennage d'une remorque. The appended drawing illustrates, by way of example, an embodiment of the device according to the present invention. Figure 1 shows the direction of movement of the axle which allows a load transfer for tipping. Figure 2 shows the invention. In these figures (R) represents the rear axle of the trailer. The arrows show the movements of the organs. Figure (3) shows the bogie (1) seen in enlarged side, and provided with axles on which are secured the four wheels (2). In (3) is articulated the bogie (1) on a frame (4) whose side members support rollers (5) which can roll on the slides (6) fixed on each side under the body. The oil pressure cylinder (V) in Figure 2 has its cylinder at the rear of the drawbar and its piston drives the rod which is coupled to the bogie. The operation of the device is very simple: When the jack brings the axles backwards the tipping can be carried out safely. The driver can dump his trailer. Finally return of the axles to the initial position. This is what happens after tipping a trailer.

L'invention s'applique à la manutention de charges que l'on propose de transporter sur les remorques agricole, et son application pour un report de charge pendant le bennage sera particulièrement appréciée pour sa simplicité comme par sa robustesse.The invention applies to the handling of loads which it is proposed to transport on agricultural trailers, and its application for a load transfer during tipping will be particularly appreciated for its simplicity as for its robustness.
