Pièce de renfort pour anneau de remorquage destiné à être agencé à l'arrière d'un châssis d'un véhicule automobile et châssis de véhicule automobile associé 10 Domaine technique de l'invention L'invention concerne les pièces de renforts recevant des anneaux de 15 remorquage, destinés à être installés à l'arrière des véhicules automobiles, en cas de nécessité et/ou selon le type de véhicule considéré. L'invention concerne plus particulièrement une pièce de renfort pour un anneau de remorquage destiné à être agencé à l'arrière d'un châssis de 20 véhicule automobile, lequel châssis comporte au moins deux longerons latéraux reliés par une traverse arrière, ladite pièce de renfort étant munie d'une platine destinée à être fixée sur la traverse arrière sensiblement en regard de l'extrémité d'un des longerons. 25 L'invention concerne également un châssis équipé d'une telle pièce de renfort. Etat de la technique 30 Il est connu de prévoir sur l'arrière d'un véhicule automobile un anneau, ou crochet, permettant son remorquage, plus communément appelé « anneau de remorquage ». De manière classique, un tel anneau de remorquage comporte une tige cylindrique destinée à être fixée, de préférence, de manière réversible, par exemple par vissage, dans le pare-choc arrière du véhicule automobile ou à l'intérieur d'un longeron de la structure de caisse du véhicule automobile. De façon classique, les efforts ou moments générés par le remorquage arrière sont repris sur un pare-chocs, ou traverse arrière, destiné notamment, entre autres fonctions, à protéger le véhicule en cas de choc arrière. Selon le véhicule considéré, la traverse arrière, dont le coût est important, n'est réservée qu'à certaines versions du véhicule, par exemple les versions pour certains pays où les conditions de sécurité sont élevées. Afin de compenser ces efforts, il est connu d'agencer une pièce de renfort sur cette traverse, pour permettre à l'anneau de remorquage de prendre appui. Il existe ainsi de nombreuses solutions pour des pièces de renfort agencées sur une traverse arrière, par exemple comme décrit dans le document EP 1 234 729, qui décrit une pièce de renfort et de support en tôle pliée. A titre d'exemple, une autre solution de pièce de renfort en tôle pliée est représentée sur la figure 1. Un châssis 1, ou structure de soubassement, d'un véhicule automobile (non représenté sur les figures pour des raisons de clarté), est représenté partiellement. Le châssis 1 comporte notamment un longeron 2 orienté longitudinalement selon une direction longitudinale X du véhicule, parallèle à un second longeron (non représenté), les deux longerons étant reliés à une traverse arrière 3 (représentée schématiquement sur la figure 1), composée par exemple d'une doublure de jupe arrière, d'un support de feu, etc. et destinée notamment à supporter le pare-chocs du véhicule. Une pièce de renfort 4, destinée à recevoir un anneau de remorquage 5, est fixée sur la traverse arrière 3 par l'intermédiaire d'une platine 6, sensiblement en regard, ou dans le prolongement, du longeron 2. La pièce de renfort 4 est réalisée par pliage à partir d'une tôle de forte épaisseur, par exemple de l'ordre de 2mm.BACKGROUND OF THE INVENTION The invention relates to the reinforcing pieces receiving rings of 15 to 30 mm. The invention relates to reinforcement pieces for a towing ring intended to be arranged at the rear of a chassis of a motor vehicle and a chassis of an associated motor vehicle. towing, intended to be installed at the rear of motor vehicles, if necessary and / or according to the type of vehicle considered. The invention relates more particularly to a reinforcement piece for a towing ring intended to be arranged at the rear of a motor vehicle chassis, which chassis comprises at least two lateral side members connected by a rear crossmember, said reinforcing piece being provided with a plate intended to be fixed on the rear cross member substantially facing the end of one of the longitudinal members. The invention also relates to a frame equipped with such a reinforcing piece. STATE OF THE ART It is known to provide on the rear of a motor vehicle a ring, or hook, allowing its towing, more commonly known as "towing ring". Conventionally, such a towing ring comprises a cylindrical rod intended to be fixed, preferably, reversibly, for example by screwing, in the rear bumper of the motor vehicle or inside a spar of the body structure of the motor vehicle. Conventionally, the forces or moments generated by the rear towing are included on a bumper, or rear cross member, intended in particular, among other functions, to protect the vehicle in the event of a rear impact. Depending on the vehicle, the rear cross-member, the cost of which is important, is reserved for certain versions of the vehicle, for example the versions for certain countries where the security conditions are high. To compensate for these efforts, it is known to arrange a reinforcing piece on this cross, to allow the towing ring to support. There are thus many solutions for reinforcing pieces arranged on a rear cross member, for example as described in the document EP 1 234 729, which describes a reinforcing piece and support sheet folded. By way of example, another solution of bent sheet metal reinforcing element is shown in FIG. 1. A chassis 1, or underbody structure, of a motor vehicle (not shown in the figures for the sake of clarity), is partially represented. The chassis 1 comprises in particular a longitudinal member 2 oriented longitudinally in a longitudinal direction X of the vehicle, parallel to a second spar (not shown), the two spars being connected to a rear cross member 3 (shown schematically in FIG. 1), composed for example rear skirt lining, fire support, etc. and intended in particular to support the bumper of the vehicle. A reinforcing piece 4, intended to receive a towing ring 5, is fixed on the rear crossmember 3 via a plate 6, substantially opposite, or in the extension, of the spar 2. The reinforcement piece 4 is made by folding from a thick sheet, for example of the order of 2mm.
Toutefois, de telles solutions présentent de nombreux inconvénients. Notamment, des pièces en tôle pliée ne se déforment pas à tous les coups en cas de choc arrière, donc n'absorbent pas assez d'énergie, ce qui génère de l'intrusion et déstabilise le fonctionnement des longerons du châssis en cas de choc arrière. De même, de telles solutions sont coûteuses et complexes à réaliser et ne présentent pas de garanties suffisantes en cas de sollicitations en chocs arrière et aussi à l'encontre des efforts engendrés par le remorquage.However, such solutions have many disadvantages. Notably, folded sheet metal parts do not deform at every stroke in the event of a rear impact, so do not absorb enough energy, which generates intrusion and destabilizes the operation of the frame side members in case of shock back. Similarly, such solutions are expensive and complex to achieve and do not have sufficient guarantees in case of stress on rear impact and also against the efforts caused by towing.
Objet de l'invention L'invention a pour but de remédier à l'ensemble des inconvénients précités et a pour objet la réalisation d'une pièce de renfort pour anneau de remorquage agencée sur le châssis d'un véhicule automobile, qui soit simple de conception, peu coûteuse et qui permette de résister de façon optimale aux différentes sollicitations du remorquage et en cas de chocs arrière. Cet objet de l'invention est caractérisé, plus particulièrement, par le fait que la pièce de renfort comporte un cône de révolution autour d'un axe longitudinal, ledit cône de révolution faisant saillie de ladite platine et comportant une embase au niveau de ladite platine et un sommet au niveau d'une face parallèle à ladite platine, de sorte à former dans ladite face un orifice destiné à recevoir une tige de l'anneau de remorquage.OBJECT OF THE INVENTION The object of the invention is to remedy all of the aforementioned drawbacks and is intended to provide a reinforcing element for a towing eye arranged on the chassis of a motor vehicle, which is simple to design, inexpensive and that allows to withstand optimally the various stresses of towing and in case of rear impact. This object of the invention is characterized, more particularly, by the fact that the reinforcement piece comprises a cone of revolution about a longitudinal axis, said cone of revolution projecting from said plate and having a base at said platen. and a vertex at a face parallel to said platen, so as to form in said face an orifice for receiving a rod of the towing ring.
D'autres avantages et caractéristiques de l'invention peuvent être considérées isolément ou en combinaison : - Ladite pièce peut être réalisée par emboutissage à partir d'un flanc de tôle métallique. - Ladite pièce peut comporter une épaisseur comprise entre 0,9mm et 2,5mm, par exemple de l'ordre de 0,9mm.Other advantages and features of the invention may be considered singly or in combination: Said part may be made by stamping from a sheet metal flank. Said part may comprise a thickness of between 0.9 mm and 2.5 mm, for example of the order of 0.9 mm.
