ELEMENT DE REMORQUAGE NOTAMMENT POUR REMORQUES A
PLATEAU.TOWING ELEMENT, ESPECIALLY FOR TRAILERS
TRAY.
La présente invention se rapporte à un élément de remorquageS notamment du type permettant de relier une remorque à plateau à un tracteur.The present invention relates to a towing element, in particular of the type enabling a flatbed trailer to be connected to a tractor.
On connaît délà de tels éléments constitués drun anneau, prolongé par une queue filetée, solidarisé à un boîtier fixé par un bras articulé prolongeant la remorque à tracter, au moyen d' un écrou traverse' par une goupille.There are known such elements consisting of a ring, extended by a threaded tail, secured to a housing fixed by an articulated arm extending the trailer to be towed, by means of a nut traversed by a pin.
Toutefois dans certaines situations telles que traction violente, démarrage, accélération ou décélération, passage de déformations du sol, des contraintes mécaniques considérables s' exercent au niveau de la tige filetée et de I' écrou, entraînant leur détérioration et le cisaillement de la goupille.However in certain situations such as violent traction, starting, acceleration or deceleration, passage of deformations of the ground, considerable mechanical stresses are exerted at the level of the threaded rod and of the nut, causing their deterioration and the shearing of the pin.
On peut ainsi assister à la désolidarisation de 1' anneau du boîtier provoquant la rupture des attelages et la dérive de la remorque.It is thus possible to witness the separation of the ring from the housing, causing the coupling to break and the trailer to drift.
Pour éviter une telle situation, I' utilisation de ce type d'assemblage implique de fréquents démontages périodiques pour le contr8le du serrage de 1' écrou, de la présence et de 1' état de la goupille, etc.To avoid such a situation, the use of this type of assembly involves frequent periodic disassembly for checking the tightening of the nut, the presence and condition of the pin, etc.
La présente invention a pour but de pallier les inconvénients ciVessus par 1' utilisation d'un nouveau type d'assemblage, qui sera maintenant décrit à titre d' exemple non limitatif au regard des figures 1 à 6 ci-lointes, se rapportant respectivement - la figure 1, à une vue en coupe longitudinale de l'ensemble de
I' assemblage selon 1' état antérieur de la technique, - la figure 2, à une vue en plan du dispositif de la figure i, - la figure 3, à l'anneau d'assemblage de la figure B vu en détail, - la figure 4, à une vue en coupe longitudinale de l'ensemble de
l'assemblage selon l'invention, - la figure 5, à une vue en plan du dispositif de la figure 4, - la figure 6, à un détail de l'assemblage selon la vue de la figure 4.The present invention aims to overcome the disadvantages ciVessus by 1 use of a new type of assembly, which will now be described by way of nonlimiting example with regard to Figures 1 to 6 below, relating respectively - Figure 1, in a longitudinal sectional view of the assembly of
I 'assembly according to the prior art, - Figure 2, to a plan view of the device of Figure i, - Figure 3, to the assembly ring of Figure B seen in detail, - Figure 4, a longitudinal sectional view of the assembly of
the assembly according to the invention, - Figure 5, a plan view of the device of Figure 4, - Figure 6, a detail of the assembly according to the view of Figure 4.
En référence aux figures 1, 2 et 3, on voit un anneau de remorquage I solidarisé par sa partie postérieure 2 à un boîtier 3 solidaire d' un attelage 4 mobile en rotation autour d' un axe horizontal 5 fixé au timon 6 de la remorque à tracter.With reference to FIGS. 1, 2 and 3, we see a towing ring I secured by its rear part 2 to a housing 3 secured to a hitch 4 movable in rotation about a horizontal axis 5 fixed to the drawbar 6 of the trailer to tow.
La solidarisation ci-dessus est effectuée par l'intermédiaire du boîtier 3 à l'intérieur duquel est solidarisé un fourreau 7, traversé par la queue 2 de l'anneau de remorquage dont 1' extrémité filetée reçoit l'écrou 8.The above connection is effected by means of the housing 3 inside which a sleeve 7 is secured, crossed by the tail 2 of the towing ring, the threaded end of which receives the nut 8.
Les rebords de ce dernier prennent appui, par l'intermédiaire d' une rondelle 9 sur l'épaulement du fourreau 7. Une goupille 10 traverse l'écrou 8 et la partie filetée de l'élément 2 de remorquage afin d' assurer leur verrouillage. La faiblesse de l'assemblage ci-dessus se situe donc au niveau des filetages et de la goupille 10, qui peuvent se rompre sous l'action des fortes contraintes évoquées précédemment.The edges of the latter bear, via a washer 9 on the shoulder of the sheath 7. A pin 10 passes through the nut 8 and the threaded part of the towing element 2 in order to ensure their locking . The weakness of the above assembly is therefore at the threads and the pin 10, which can break under the action of the strong stresses mentioned above.
L'objet de l'invention se situe dans un nouvel élément de remorquage visible aux figures 4 et 5 et en détail à la figure 6. The object of the invention is located in a new towing element visible in FIGS. 4 and 5 and in detail in FIG. 6.
On retrouve la disposition générale de nombreux éléments constituant
I' assemblage précédent - le boîtier 3, - 1' attelage 4, - l'axe horizontal 5, - le timon 6 de la remorque.We find the general arrangement of many elements constituting
I 'previous assembly - the housing 3, - 1 hitch 4, - the horizontal axis 5, - the drawbar 6 of the trailer.
Par contre, un changement intervient au niveau de la structure de la partie postérieure 60 de l'anneau de remorquage 1, vu en détail à la figure 6 ; cette dernière comporte un talon 61, venu de fonderie puis usiné aux cotes, qui remplace le système antérieur de vis > écrou - rondelle - goupille, particulièrement fragile au niveau du filetage, et supprime le démontage périodique de vérification. La pièce ci-dessus
coopère avec le boîtier 3 qui comporte à à intérieur des pièces d'appui
62 - 63 pour la tête 61 de la pièce 60.By cons, a change occurs at the structure of the rear part 60 of the towing eye 1, seen in detail in Figure 6; the latter comprises a heel 61, which came from the foundry and then machined at the sides, which replaces the previous system of screw> nut - washer - pin, particularly fragile at the level of the thread, and eliminates the periodic disassembly of verification. The room above
cooperates with the housing 3 which has inside support parts
62 - 63 for the head 61 of the part 60.
Des essais de résistance à la traction effectués sur 1' élément de
remorquage selon l'invention ont montré qu' audelà de 120 tonnes de
traction, c' est 1' anneau 1 lui-même qui cède et non sa partie
postérieure coopérant avec le boîtier 3, contrairement aux produits
homologues selon la technique antérieure. Tensile strength tests performed on the element
towing according to the invention have shown that beyond 120 tonnes of
traction, it is the ring 1 itself which yields and not its part
rear cooperating with the housing 3, unlike the products
counterparts according to the prior art.
