Abstract
Description
La présente invention concerne des flèches d'attelage de remorques, notamment de remorques agricoles telles que, par exemple, des tonnes à lisier. The present invention relates to trailer hitch arrows, in particular agricultural trailers such as, for example, slurry tonnes.
Sur une remorque agricole, la flèche d'attelage consiste généralement en un bras fixé rigidement à l'avant du châssis. Une telle flèche présente l'inconvénient de transmettre au tracteur les secousses et les chocs dûs aux chaos de la remorque, dont résulte beaucoup d'inconfort pour le conducteur. On a farm trailer, the drawbar generally consists of an arm rigidly attached to the front of the chassis. Such an arrow has the drawback of transmitting to the tractor the jolts and shocks due to the chaos of the trailer, which results in a lot of discomfort for the driver.
Pour résoudre ce problème, on a pensé à donner de la souplesse à l'attelage en prévoyant un ressort sur la flèche. Dans un montage connu, la flèche est articulée, à la manière d'un balancier, autour d'un axe horizontal sous l'avant du châssis. Par rapport à l'axe, la partie avant de la flèche est beaucoup plus longue que la partie arrière et cette dernière est prolongée par un ressort à lames à déformation dans le plan vertical. Un moyen de retenue sous le châssis maintient en place l'extrémité arrière du ressort à lames, lui permettant toutefois de se déplacer légèrement vers l'avant ou l'arrière en fonction de la flexion ou de l'extension du ressort. To solve this problem, we thought to give flexibility to the hitch by providing a spring on the boom. In a known assembly, the boom is articulated, in the manner of a pendulum, around a horizontal axis under the front of the chassis. Relative to the axis, the front part of the boom is much longer than the rear part and the latter is extended by a leaf spring with deformation in the vertical plane. A retaining means under the chassis holds the rear end of the leaf spring in place, however allowing it to move slightly forward or back depending on the flexion or extension of the spring.
Le montage d'une telle flèche nécessite qu'à l'avant, le dessous de la remorque soit dégagé, ce qui n'est pas toujours le cas. The mounting of such a boom requires that at the front, the underside of the trailer be released, which is not always the case.
Un objet de la présente invention consiste donc à prévoir une flèche d'attelage à ressort qui, par rapport à l'avant du châssis, ne dépasse pas vers l'arrière. An object of the present invention therefore consists in providing a spring-loaded towing arrow which, with respect to the front of the chassis, does not protrude towards the rear.
Selon une caractéristique de l'invention, la flèche comprend un bras dont l'extrémité arrière est articulée sur un axe horizontal à l'avant du châssis et, au-dessus ou sous ledit axe, se trouve un moyen de fixation de l'extrémité arrière d'un ressort travaillant à la flexion, ledit bras comportant un moyen de retenue de l'extrémité avant dudit ressort. According to a characteristic of the invention, the boom comprises an arm whose rear end is articulated on a horizontal axis at the front of the chassis and, above or under said axis, is a means for fixing the end rear of a spring working on bending, said arm comprising means for retaining the front end of said spring.
Selon une autre caractéristique de l'invention, ledit axe horizontal et ledit ressort à lames sont fixés à l'avant du châssis par l'intermédiaire d'une console comprenant une plaque verticale de fixation au châssis, une plaque sensiblement horizontale de fixation du ressort et deux goussets latéraux, entre lesdites plaques, dans lesquels se trouvent les paliers dudit axe. According to another characteristic of the invention, said horizontal axis and said leaf spring are fixed to the front of the chassis by means of a console comprising a vertical plate for fixing to the chassis, a substantially horizontal plate for fixing the spring. and two lateral gussets, between said plates, in which the bearings of said axis are located.
Selon une autre caractéristique de l'invention, ledit bras a une section en U, ou rectangulaire, le ressort se trouvant à l'intérieur du bras et le moyen de retenue de l'extrémité avant dudit ressort étant un couloir solidaire du bras dont la hauteur n'est que très légèrement supérieure à celle de ladite extrémité. According to another characteristic of the invention, said arm has a U-shaped or rectangular section, the spring being inside the arm and the means for retaining the front end of said spring being a passage secured to the arm, the height is only very slightly greater than that of said end.
Selon une autre caractéristique de l'invention, ledit ressort est un ressort à lames à déformation dans le plan vertical. According to another characteristic of the invention, said spring is a leaf spring with deformation in the vertical plane.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparattront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue de côté d'une flèche selon l'invention,
la Fig. 2 est une vue en coupe longitudinale de la Fig. 1, et
la Fig. 3 est une vue de. dessus de ladite flèche, sans sa paroi supérieure.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a side view of an arrow according to the invention,
Fig. 2 is a view in longitudinal section of FIG. 1, and
Fig. 3 is a view of. above said arrow, without its upper wall.
La flèche, Fig. 1, est constituée par un bras creux 1 à section carrée ou rectangulaire décroissante de l'arrière vers l'avant. A l'avant, le bras 1 est muni d'un anneau d'accrochage 2. The arrow, Fig. 1, is constituted by a hollow arm 1 with a square or rectangular section decreasing from the rear towards the front. At the front, the arm 1 is provided with a hooking ring 2.
Le bras 1 est articulé sur un axe horizontal 3 passant dans des paliers prévus sur une console4 fixée à l'avant du châssis 5 de la remorque. L'axe 3 est bloqué de façon classique, généralement au moyen de goupilles. The arm 1 is articulated on a horizontal axis 3 passing through bearings provided on a console 4 fixed to the front of the chassis 5 of the trailer. The axis 3 is locked in a conventional manner, generally by means of pins.
La console 4 comporte une plaque 6 fixée solidement à la traverse avant du châssis 5 et une plaque 7 sensiblement horizontale ou légèrement en pente vers l'avant. Entre les plaques 6 et 7, sont soudés deux goussets latéraux 8 dans lequels se trouvent les paliers de l'axe 3. The console 4 comprises a plate 6 fixed securely to the front cross member of the chassis 5 and a plate 7 substantially horizontal or slightly sloping forward. Between the plates 6 and 7, two lateral gussets 8 are welded in which the bearings of the axis 3 are located.
L'extrémité arrière du bras 1 coiffe la console 4 et elle comporte une lumière ronde dans chacune de ses parois latérales pour le passage de l'axe 3. The rear end of the arm 1 covers the console 4 and it has a round light in each of its side walls for the passage of the axis 3.
Sur la plaque 7, entre les goussets 8, est fixée l'extrémité arrière d'un ressort à lames 9, au moyen de brides 10. Les brides 10 sont des cavaliers dont les extrémités sont filetées et passent dans des trous de la plaque 7. Elles sont serrées au moyen d'écrous 11 sous la plaque 7. On the plate 7, between the gussets 8, is fixed the rear end of a leaf spring 9, by means of flanges 10. The flanges 10 are jumpers whose ends are threaded and pass through holes in the plate 7 They are tightened by means of nuts 11 under the plate 7.
L'extrémité avant du ressort 9 a une tête 12 de section verticale circulaire. Le ressort 9 est à l'intérieur du bras 1 et sa tête 12 est logée dans un couloir 13 fixé aux faces internes des parois du bras 1. La largeur et la hauteur du couloir 13 sont très légèrement supérieures à la largeur du ressort 9 et à la hauteur de la tête 12, respectivement, Figs. 2 et 3. Le couloir 13 a une certaine longueur, si bien que la tête est libre de se déplacer légèrement le long de ce dernier en fonction des déformations du ressort 9, mais qu'elle n'a pas la possibilité d'en sortir. The front end of the spring 9 has a head 12 of circular vertical section. The spring 9 is inside the arm 1 and its head 12 is housed in a corridor 13 fixed to the internal faces of the walls of the arm 1. The width and the height of the corridor 13 are very slightly greater than the width of the spring 9 and at the height of the head 12, respectively, Figs. 2 and 3. The passage 13 has a certain length, so that the head is free to move slightly along the latter according to the deformations of the spring 9, but that it does not have the possibility of leaving it .
La flèche de l'invention est adaptable à toutes les remorques, notamment celles pour lesquelles elle n'était pas prévue à la fabrication. D'autre part, elle est plus simple et donc moins chère à mettre en oeuvre que les dispositifs existants. The boom of the invention is adaptable to all trailers, in particular those for which it was not intended for manufacture. On the other hand, it is simpler and therefore cheaper to implement than existing devices.
