Description
Ensemble d'essieux destinés à équiper des bennes de moyens et gros tonnages
La présente invention a pour objet un ensemble de deux essieux suiveurs en montage inversé à commande alternée, destins à équiper des bennes de moyens ou gros tonnages utilisées pour les travaux agricoles, notamment pour le transport des betteraves par exemple, ou les travaux publics . Set of axles intended to equip skips with medium and large tonnages
The present invention relates to a set of two follower axles in reverse assembly with alternating control, intended to equip skips with medium or large tonnages used for agricultural work, in particular for the transport of beets for example, or public works.
Le poids en charge de telles bennes ne peut excéder généralement plus de dix à douze tonnes. The laden weight of such tippers cannot generally exceed more than ten to twelve tonnes.
En effet,pour les charges supérieures leur emploi devient difficile en terrain cultivé, les roues s'enfonçant profondément dans le sol en le détériorant, de meme que les revetements routiers qui supportent mal lé passage de tels engins. In fact, for higher loads, their use becomes difficult in cultivated ground, the wheels sinking deep into the ground, deteriorating it, as are the road surfaces which poorly support the passage of such vehicles.
Pour pallier à ces inconvénients, on a doté ces sennes de plusieurs essieux, afin d'augmenter le nombre de roues et de répartir la charge au sol sur une plus grande surface, mais on s'est vite heurté au problème de l'encombrement de la benne et à son manque de maniabilité notamment dans les virages. To overcome these drawbacks, these seines were equipped with several axles, in order to increase the number of wheels and to distribute the load on the ground over a larger area, but we quickly encountered the problem of the size of the bucket and its lack of maneuverability, especially when cornering.
Pour remédier à cet inconvénient on a dotc ces sennes d'essieux pouvant etre relevés lors des manoeuvres, seul moyen efficace pour ne pas détruire les sols et revêtements tout en n'imposant pas d'énormes contraintes mécaniques sur l'essieu avant du boggie. Dans un tel dispositif la difficulté était d'opter, soit pour un essieu autodirecteur avant, soit pour un essieu autodirecteur arrière. Dans le premier cas, en marche avant, les roues de l'essieu sui veur étant parallèles à l'axe de virage, anticipent le rayon et coupent, par exemple, un virage ; dans le second cas, en marche arrière, le vdhicule ripe et ne suit pas l'axe de recul. To overcome this drawback we have endowed these axle seines that can be raised during maneuvers, the only effective way not to destroy the floors and coverings while not imposing enormous mechanical stresses on the front axle of the bogie. In such a device, the difficulty was to opt either for a front self-steering axle or for a rear self-steering axle. In the first case, in forward gear, the wheels of the following axle being parallel to the turning axis, anticipate the radius and cut, for example, a turn; in the second case, in reverse, the vehicle rips and does not follow the axis of recoil.
La présente invention remédie à ces inconvénients en supprimant le dilemme essieu autodirecteur avant ou arrière en proposant d'équiper les bennes ou analogues de deux essieux suiveurs en montage inversé à commande alternée,ce système pouvant être monté sur boggies ou en tandem. The present invention overcomes these drawbacks by eliminating the dilemma of front or rear self-steering axle by proposing to equip skips or the like with two follower axles in reverse assembly with alternating control, this system being able to be mounted on bogies or in tandem.
Selon l'invention, en marche avant l'essieu avant étant bloqué l'essieu arrière est autodirecteur; en marche arrière l'essieu arrière est bloqué, l'essieu avant deve nant autodirecteur suit l'impulsion donne par le tracteur facilitant la manoeuvre. L'ensemb..le est commandé par un circuit hydraulique à double effet de type connu. Le rayon de braquage permis à chaque essieu est de 200 environ. According to the invention, when moving forward the front axle being locked the rear axle is self-steering; in reverse the rear axle is locked, the front axle becoming self-steering follows the impulse given by the tractor facilitating the maneuver. The assembly is controlled by a double-acting hydraulic circuit of known type. The turning radius allowed for each axle is approximately 200.
L'invention sera mieux comprise à la lecture de la description qui suit d'une de ses réalisations préférées et à l'examen des dessins annexés sur lesquels:
La figure 1 représente schématiquement un châssis de benne comportant deux essieux suiveurs selon l'.inven- tion, l'essieu arrière étant autodirecteur.The invention will be better understood on reading the following description of one of its preferred embodiments and on examining the appended drawings in which:
FIG. 1 schematically represents a tipper chassis comprising two follower axles according to the invention, the rear axle being self-steering.
La figure 2 représente le châssis de la figure 1, l'essieu avant étant autodirecteur. Figure 2 shows the chassis of Figure 1, the front axle being self-steering.
Les figures 3a et 3b représentent schématiquement les avontages de l'invention lorsqu'on manoeuvre une benne en marche avant et en marche arrière. Figures 3a and 3b schematically show the advantages of the invention when maneuvering a bucket in forward and reverse.
En se reportant à la figure 1, on voit schématiquement représenté en traits mixtes un châssis 1 d'une benne de tonnage moyen comportant deux essieux suiveurs 2 et 3 selon l'invention. Ces essieux rigides sont montés sur le châssis 1 par l'intermédiaire d'une suspension de type connu non représentée; chaque essieu peut entre directeur et comporte une barre d'accouplement 4 reliant le pivot 5 de chaque moyeu 6 par l'intermédiaire d'un levier d'accouplement 7. Referring to Figure 1, there is shown schematically in dashed lines a chassis 1 of a medium tonnage bucket having two axle followers 2 and 3 according to the invention. These rigid axles are mounted on the chassis 1 by means of a suspension of known type, not shown; each axle can between the steering and has a coupling bar 4 connecting the pivot 5 of each hub 6 by means of a coupling lever 7.
Le rayon de braquage de chaque roue (non représentée) peut être de 200 environ. The turning radius of each wheel (not shown) can be approximately 200.
Des vérins hydrauliques 8 sont fixés aux extrémités de chaque essieu 2-3 au moyen d'une bride 9, de manitre telle que la tige 10 de chaque vérin 8 puisse venir en appui sur une hutée réglable 11 montée sur le levier d'accouplement 7 de chaque moyeu 6. Les vérins 8 sont couplés d'une manière connue à un circuit hydraulique non représenté avec interposition d'une commande à double effet permettant d'agir soit sur les deux vérins 8 portés par l'essieu avant 2 ou sur ceux portés par l'essieu arrière 3. Hydraulic cylinders 8 are fixed to the ends of each axle 2-3 by means of a flange 9, a handle such that the rod 10 of each cylinder 8 can come to bear on an adjustable hute 11 mounted on the coupling lever 7 of each hub 6. The cylinders 8 are coupled in a known manner to a hydraulic circuit not shown with the interposition of a double-acting control making it possible to act either on the two cylinders 8 carried by the front axle 2 or on those carried by the rear axle 3.
Dans l'exemple représenté figure 1 les vérins 8 portés par l'essieu avant 2 bloquent le pivotement du moyeu 6,1'essieu arrière 3 étant suiveur, et pouvant de ce fait prendre un angle de braquage pouvant aller jusqu'd 200. In the example shown in FIG. 1, the jacks 8 carried by the front axle 2 block the pivoting of the hub 6,1 'rear axle 3 being a follower, and therefore being able to take a steering angle of up to 200.
La figure 2 représente le-même châssis que celui de la figure 1, mais dans l-'exemple représenté c'est le pivotement de l'essieu arrière qui est bloqué, la tige 10 de chaque vérin 8 prenant appui sur chaque butée 11 portée par le levier d'accouplement 7, et c'est l'essieu avant qui est autodirecteur. Un tel montage donne une très grande ma viabilité à l'ensemble comme représenté schématiquement sur les figures 3a et 3b. En marche avant (fig. 3a): l'essieu avant 20 de la benne B étant bloqué, l'essieu arrière 30 est suiveur et autodirecteur et dans un virage le rayon de braquage déporte la benne B tirée par un tracteur T vers l'extérieur et elle se présente face à l'entrée dans l'axe. Figure 2 shows the same chassis as that of Figure 1, but in the example shown it is the pivoting of the rear axle which is blocked, the rod 10 of each cylinder 8 bearing on each stop 11 carried by the coupling lever 7, and it is the front axle which is self-steering. Such an assembly gives a very high viability to the assembly as shown schematically in Figures 3a and 3b. In forward gear (fig. 3a): the front axle 20 of the bucket B being locked, the rear axle 30 is follower and self-steering and in a turn the turning radius shifts the bucket B pulled by a tractor T towards the outside and it faces the entrance to the axis.
En marche arrière (fig. 3b): l'essieu arrière 30 étant bloqué l'essieu avant 20 devient autodirecteur, et il suit automatiquement l'impulsion donnée par le tracteur T; dans ce cas, il n'y a plus de risque de voir l'essieu arrière 30 suivre une ornière et riper sur un sol en mauvais état.In reverse (fig. 3b): the rear axle 30 being locked the front axle 20 becomes self-steering, and it automatically follows the impulse given by the tractor T; in this case, there is no longer any risk of seeing the rear axle 30 follow a rut and slip on ground in poor condition.
Bien entendu, des modifications peuvent être apportées à la réalisation décrite, par exemple on peut appliquer l'invention à des boggies,ou la combiner avec des essieux releveurs, etc. sans pour autant sortir du cadre de la présente invention. Of course, modifications can be made to the embodiment described, for example one can apply the invention to bogies, or combine it with lifting axles, etc. without departing from the scope of the present invention.
