Abstract

The mechanism keeps the steering wheels of a farm implement, attached to the three-point mounting of a tractor, in track with the latter. If the implement veers to the left or the right of the path followed by the tractor, the distance between them varies, causing movement of a lever acting on the steering wheels. This distance variation can be amplified to a varying degree by altering the lever length.

Description

La présente invention a pour objet à titre de produit industriel nouveau, un dispositif permettant d'asservir et d'aligner dans l'axe de marche du tracteur, les roues directrices d'un instrument agricole attelé en trois points. The subject of the present invention is, as a new industrial product, a device making it possible to control and align in the axis of travel of the tractor, the steered wheels of an agricultural implement harnessed at three points.

Le but de cette invention est de maintenir automatiquement l'instrument en alignement avec l'axe de marche du tracteur sans qu'une personne soit nécessaire pour agir sur les roues directrices de l'instrument. The object of this invention is to automatically maintain the instrument in alignment with the axis of travel of the tractor without a person being necessary to act on the steered wheels of the instrument.

L'ensemble se compose d'un support 1 fixé sur le bâti de l'ins trument, d'un pivot 2, sur lequel peut pivoter un renvoi d'angle composé de deux branches dont une 4, est plus courte que l'autre. The assembly consists of a support 1 fixed on the frame of the instrument, of a pivot 2, on which can rotate a bevel gear composed of two branches, one of which 4, is shorter than the other .

La branche 3, comporte une glissière ou peut se déplacer pour réglage le pivot 5. 6, est une barre de liaison reliant les roues directrices de l'instrument au dispositif objet de la présente invention.The branch 3, has a slide or can move to adjust the pivot 5. 6, is a connecting bar connecting the steering wheels of the instrument to the device object of the present invention.

7, est un levier réglable en longueur et prenant appui sur un point situé sur le coté du tracteur et le plus en avant possible.7, is a lever adjustable in length and bearing on a point located on the side of the tractor and as far forward as possible.

Fonctionnement : tout instrument agricole attelé en trois points est attelé sur la barre supérieure de poussée et sur les deux bras inférieurs d'attelage. Ces bras d'attelage inférieurs sont munis de rotules afin de permettre un déplacement latéral de l'instrument au travail. Or ; lors de ce déplacement latéral les bras d'attelage décrivent un arc de cercle, ce qui entrain que tout déplacement latéral de l'instrument se traduit en même temps par un déplacement longitudinal, c'est à dire d'avant en arrière. Operation: any agricultural implement hitched in three points is hitched to the upper push bar and the two lower hitch arms. These lower coupling arms are fitted with ball joints to allow lateral movement of the implement at work. Gold ; during this lateral movement, the coupling arms describe an arc of a circle, which means that any lateral movement of the instrument results at the same time in a longitudinal movement, that is to say from front to back.

En appliquant cette résultante sur le levier 7, lequel prend appui sur un point situé sur le coté du tracteur et le plus en avant possible, et en amplifiant ce mouvement par réglage du pivot 5, dans la glissière il s'en suit que : dès que l'instrument n'est plus aligné avec l'axe de marche du tracteur, les roues directrices se mettent automatiquement en position de correction de trajectoire et l'instrument s'aligne alors automatiquement sur l'axe de marche du tracteur. By applying this result to the lever 7, which is supported on a point located on the side of the tractor and as far forward as possible, and by amplifying this movement by adjusting the pivot 5, in the slide it follows that: the instrument is no longer aligned with the tractor's travel axis, the steered wheels automatically move to the path correction position and the instrument then automatically aligns with the tractor's travel axis.
