Art anterieur et probleme pose Dans le cadre de la fabrication de vehicules automobiles, il est prevu d'equiper chacune de celles-ci de moyens permettant la fixation d'un anneau de remorquage, utilisable en cas de panne ou d' accidents. Ce type d'anneau doit pouvoir etre fixe sur une piece de fixation, fixee elle-meme sur une partie rigide principale du chassis du vehicule, par exemple un longeron. Il doit pouvoir etre place aussi  PRIOR ART AND PROBLEM POSED In the context of the manufacture of motor vehicles, it is planned to equip each of these with means allowing the fixing of a towing ring, usable in the event of breakdown or accidents. This type of ring must be able to be fixed on a fixing piece, itself fixed on a main rigid part of the chassis of the vehicle, for example a spar. It must be able to be placed too

bien a l' avant qu'a l'arriere de l 'automobile.  well at the front than at the back of the car.

Les moyens de fixation traditionnels de l'anneau de remorquage vent realises sous la forme d'une piece de fixation soudee par plusieurs points sur un longeron du chassis de ['automobile. Sur cette piece est fixee un tube carre comportant un taraudage permettant de recevoir la partie filetee de l'anneau de remorquage. Ce tube est done de section carree et est soude dans la piece de fixation par des cordons de soudure. En consequence, la pidce de fixation, dont une partie de la forme externe doit s' adapter a la forme du longeron sur lequel elle est fixee a lavant ou l'arribre de la voiture, doit comporter un evidement interne de section carree relativement long, destine a  The traditional means of fixing the wind towing ring produced in the form of a fixing piece welded by several points on a spar of the chassis of the automobile. On this piece is fixed a square tube comprising a thread allowing to receive the threaded part of the towing eye. This tube is therefore of square section and is welded in the fixing piece by weld beads. Consequently, the fixing part, part of the external shape of which must adapt to the shape of the spar on which it is fixed to the front or to the rear of the car, must have an internal recess of relatively long square section, intended for

recevoir la forme externe du tube carre.  receive the external shape of the square tube.

Ce systame presente plusieurs inconvenients, notamment lors de la fixation de ces differentes pieces les unes sur les autres et sur le longeron. En effet, compte tenu du fait qu'on utilise le soudage par cordon, il se produit un choc thermique sur les pieces concernees. Un tel choc thermique denature ainsi la structure interne moleculaire des materiaux constituent ces differentes piaces. De plus, si la section carree permet d'arreter en rotation le tube de fixation, sa  This system has several drawbacks, especially when fixing these different pieces on top of each other and on the spar. In fact, taking into account the fact that cord welding is used, there is a thermal shock on the parts concerned. Such a thermal shock thus denatures the internal molecular structure of the materials constituting these different parts. In addition, if the square section allows rotation to stop the fixing tube, its

fabrication n'est pas bon marche.manufacturing is not cheap.

Le but de l' invention est de remedier a ces inconvenients, en proposant d'autres moyens de fixation de l'anneau de remorquage sur la structure du chassis  The object of the invention is to remedy these drawbacks by proposing other means of fixing the towing eye to the chassis structure.

Selon une caracteristique technique principale de l' invention, la fixation de la douille de fixation dans les pieces de fixation s'effectue par bouterollage des deux pieces de fixation autour de la  SUMMARY OF THE INVENTION To this end, the main object of the invention is a system for fixing a towing ring to a motor vehicle, the latter comprising: - at least one rigid chassis element; and - at least one vehicle end shield having a determined external shape. The system comprises: - a fixing sleeve having a thread and being of determined external shape; - two pieces for fixing the fixing socket to the chassis, each having an internal part with a shape complementary to the shape of the fixing socket and lateral parts with a shape complementary to that of the end shield vehicle; and - a removable towing ring and having a threaded rod intended to be screwed into the thread of the fixing sleeve. According to a main technical characteristic of the invention, the fixing of the fixing sleeve in the fixing pieces is carried out by snapping the two fixing pieces around the

douille de fixation.fixing sleeve.

Definition: on denomme par << bouterollage >> a une fixation analogue au rivetage, le pied de chaque rivet faisant partie integrante d'une premiere des deux piaces a fixer, la t8te etant ecrasee de facon a  Definition: we denote by "bolting" a fixing similar to riveting, the foot of each rivet being an integral part of a first of the two parts to be fixed, the head being crushed so as to

l' invention La figure 1 montre done l'arriere d'une automobile 1 et en particulier le bouclier arriere 2, constituent la base de la partie arriere de l 'automobile. Un tel bouclier arribre 2 fait, entre autres, office de pare-chocs. Un couvercle 3 a ete represente a l'exterieur du bouclier arriere 2, legerement en saillie de celui-ci.

Such a shield arrives 2 acts, among other things, as a bumper. A cover 3 has been shown on the outside of the rear shield 2, slightly projecting from it. It is placed opposite a location 4, shown in broken lines, or the fixing rod of a towing ring must be fixed. This location 4 corresponds to that of a system fixing socket

On note que, dans l'exemple represente a la figure 1, l'anneau de remorquage est fixe a l'arriere de l 'automobile. On peut, de maniere equivalente, imaginer une fixation de celui-ci a l' avant de ['automobile. En se reportant a la figure 2, les elements principaux du systeme de fixation selon l' invention, pour un anneau de remorquage 10, vent une douille de  Note that, in the example shown in Figure 1, the towing eye is fixed to the rear of the automobile. One can, equivalently, imagine a fixing thereof to the front of the automobile. Referring to FIG. 2, the main elements of the fastening system according to the invention, for a towing ring 10, wind a bushing

La douille de fixation 14 est de forme cylindrique, de maniere a etre fabriquee sur la base d'un tube. Wile possede a une extremite et a l'interieur un taraudage 16. Celui-ci est. de preference, conforme, non pas par usinage, c'est-a-dire par enlevement de metal, mais par repoussage sans enlevement de matiere. En correspondence, une tige de fixation 11 de l'anneau de remorquage 10 possede, a son extremite, un filetage 12 d'un diametre et de pas correspondents a ceux du taraudage 16 de la douille de fixation 14, de maniere a pouvoir y etre fixee par vissage. La douille de fixation 14 possede des ergots de blocage en rotation et en translation. En effet, la douille de fixation 14 doit etre fixee sur l 'automobile de maniere fixe, sans possibilite de mouvements quelconques. Les deux pieces de f_xation 20A et 20B vent prevues pour recevoir la douille de fixation 16 et possedent des trous 25 dont le nombre, la forme et l 'emplacement correspondent a ceux des ergots 15 de la douille de fixation 14. La hauteur des ergots 15 est relativement modeste. En effet, ils vent obtenus par repoussage d'une petite partie de la matiere constituent la surface externe de la douille de fixation 14 a leur base. Les zones 19 indiquent l'endroit ou la matiere a ete repoussee pour former ces ergots 15. On utilise egalement le terme << dechaussage >> pour exprimer ce type de travail par deformation de la matiere. De meme, de maniere a ne pas utiliser de machine-outil d'usinage, le taraudage 16 de la douille de fixation 14 est forme par repoussage de  The fixing sleeve 14 is cylindrical in shape, so as to be manufactured on the basis of a tube. Wile has at one end and inside a tapping 16. This one is. preferably, conform, not by machining, that is to say by removing metal, but by embossing without removing material. In correspondence, a fixing rod 11 of the towing eye 10 has, at its end, a thread 12 of a diameter and pitch corresponding to those of the internal thread 16 of the fixing sleeve 14, so as to be able to be there fixed by screwing. The fixing sleeve 14 has pins for locking in rotation and in translation. Indeed, the fixing sleeve 14 must be fixed to the automobile in a fixed manner, without the possibility of any movement. The two fixing pieces 20A and 20B are provided to receive the fixing sleeve 16 and have holes 25 whose number, shape and location correspond to those of the pins 15 of the fixing sleeve 14. The height of the pins 15 is relatively modest. Indeed, they wind obtained by pushing back a small part of the material constitute the external surface of the fixing sleeve 14 at their base. The zones 19 indicate the place where the material was pushed back to form these lugs 15. The term "heaving" is also used to express this type of work by deformation of the material. Likewise, so as not to use a machine tool, the internal thread 16 of the fixing sleeve 14 is formed by pushing back

Les deux pieces de fixation 20A et 20B doivent etre fixees de maniere definitive sur une partie rigide du bati de l' automobile, a savoir les t81es environnantes du longeron qui se prolonge vers l'arriere, ou eventuellement vers l' avant de l 'automobile. En fonction des differentes formes de ces pieces environnantes, ces pieces de fixation 20A et 20B ont deux parties laterales, non representees, dont la forme est adaptee en correspondence a la forme de ces pieces environnantes du longeron et du bouclier arriere  The two fastening pieces 20A and 20B must be permanently fixed to a rigid part of the frame of the automobile, namely the surrounding legs of the side member which extends towards the rear, or possibly towards the front of the automobile. . Depending on the different shapes of these surrounding pieces, these fastening pieces 20A and 20B have two lateral parts, not shown, the shape of which is adapted in correspondence to the shape of these surrounding pieces of the spar and the rear bumper.

Ces pieces de fixation 20A et 20B possedent chacune des trous de blocage en translation ou en rotation 25, places sur une generatrice du demicylindrique 24A formant la partie s'adaptant a la forme cylindrique de la douille de fixation 14. De preference, on choisit la generatrice se trouvant a egale distance des deux parties laterales de la piece de fixation 20A et 20B. Le positionnement de ces trous de blocage en rotation 25 et en translation correspond a l 'emplacement des ergots 15 de la douille de fixation 14. Il en est de meme pour la forme de ces elements qui vent en correspondence, de maniere a ce que chaque ergot 15 penetre facilement dans un trou de blocage en  These fastening pieces 20A and 20B each have translation or rotation blocking holes 25, placed on a generator of the semi-cylindrical 24A forming the part adapting to the cylindrical shape of the fixing sleeve 14. Preferably, the generator located at equal distance from the two lateral parts of the fastener 20A and 20B. The positioning of these locking holes in rotation 25 and in translation corresponds to the location of the lugs 15 of the fixing sleeve 14. It is the same for the shape of these elements which wind in correspondence, so that each lug 15 easily enters a blocking hole in

La piece de fixation 20A representee dans la partie superieure de la figure 2 possade trots trous de fixation 22A, places sur le debut des parties laterales en grande partie non representees, pres de la forme demi-cylindrique 24A. En correspondence, l'autre piace de fixation 20B representee dans le teas de la figure possede des pastes de fixation 22B, en meme nombre, de meme forme et placees au meme endroit que les trous de fixation 22A de la premiere piece de fixation 20A. Ces pastes vent obtenues par decoupage et enforcement partiel de la matiere constituent le debut de chacune  The fixing piece 20A represented in the upper part of FIG. 2 has three fixing holes 22A, placed at the start of the lateral parts which are largely not shown, near the semi-cylindrical shape 24A. In correspondence, the other fixing piece 20B represented in the teas of the figure has fixing strips 22B, in the same number, of the same shape and placed in the same place as the fixing holes 22A of the first fixing piece 20A. These pastes wind obtained by cutting and partial enforcement of the material constitute the beginning of each

Cette figure 2 montre bien que la douille de fixation 14 peut etre placee de maniere fixe a l'interieur du cylindre forme par les deux pieces de fixation 20A et 20B, les ergots 15 etant introduits dans les trous de blocage en rotation et en translation 25. Ainsi, un bouterollage peut alors etre effectue. En effet, il consiste a aplatir le sommet de chacune des pastes de fixation 22B de maniere a l'ecraser, augmentant son diametre, la matiere de cette extremite de chacune des pastes 22B debordant au-dessus de chacun des trous de fixation 22A. Cette operation est equivalente a un rivetage. Ainsi, cet ensemble est  This FIG. 2 clearly shows that the fixing sleeve 14 can be placed in a fixed manner inside the cylinder formed by the two fixing pieces 20A and 20B, the lugs 15 being introduced into the holes for blocking in rotation and in translation 25 In this way, a bolting can then be carried out. Indeed, it consists in flattening the top of each of the fixing steps 22B so as to crush it, increasing its diameter, the material of this end of each of the steps 22B projecting above each of the fixing holes 22A. This operation is equivalent to riveting. So this set is

L'anneau de remorquage 10 possede une tige 11 de longueur non determinee, mais dont l'extremite est terminee par un filetage 12 de pas et de diametre correspondent au taraudage 16 pratique dans une extremite de la partie interieure de la douille de fixation 14. Ainsi, l'anneau de remorquage 10 peut etre visse dans la douille de fixation 14 fixse de facon  The towing eye 10 has a rod 11 of undetermined length, but the end of which is terminated by a thread 12 of pitch and diameter corresponding to the thread 16 practical in one end of the inner part of the fixing sleeve 14. Thus, the towing eye 10 can be screwed into the fixing sleeve 14 so fixed

La figure 3 permet de voir, en coupe, la fixation de ['ensemble des deux pieces de fixation 20A et 20B autour de la douille de fixation 14. On y retrouve des ergots 15 engages chacun dans un trou de fixation en rotation en translation 25. On precise que ces derniers vent diametralement opposes et places a 90 par rapport au plan definissant les parties  FIG. 3 shows, in section, the fixing of the assembly of the two fixing pieces 20A and 20B around the fixing sleeve 14. There are lugs 15 engaged each in a fixing hole in rotation in translation 25 It is specified that the latter are diametrically opposite and placed at 90 relative to the plane defining the parts.
