Description
1 L'invention concerne un procédé d'allègement de leviers et de pédales, tout en conservant leur rigidité d'origine, et son application à l'industrie automobile pour la réalisation de pédales et de leviers notamment. The invention relates to a method of lightening levers and pedals, while maintaining their original rigidity, and its application to the automotive industry for the realization of pedals and levers in particular.
L'industrie automobile se soucie, depuis quelque temps, d'obtenir des gains de masse sur tous les composants d'un véhicule automobile en faisant largement appel aux matières plastiques pour les parties non travaillantes, mais cette préoccupation gagne maintenant les pièces travaillantes, dans la mesure où leurs caractéristiques mécaniques d'origine peuvent être conservées ; ceci, même pour des éléments très sollicités lors de l'utilisation des véhicules, tels que les pédales de frein par exemple encore très largement métalliques, qu'il s'agisse de pédales à transmission directe d'accroche de la tige de commande (type booster de frein), ou de pédales à transmission déportée, bien qu'une solution hybride soit déjà apparue sur le marché, car il faut, bien sûr, que la rigidité obtenue par cette solution reste identique à celle de la solution entièrement métallique. The automotive industry has been concerned for some time with mass savings on all components of a motor vehicle by making extensive use of plastics for non-working parties, but this concern is now gaining the extent to which their original mechanical characteristics can be preserved; this, even for highly stressed elements when using vehicles, such as brake pedals, for example still largely metal, whether pedals direct transmission of grip of the control rod (type brake booster), or pedals with remote transmission, although a hybrid solution has already appeared on the market, because it must, of course, that the rigidity obtained by this solution remains identical to that of the all-metal solution.
Il s'agit généralement de l'association d'un insert métallique et d'une matière plastique chargée en fibres de verre, faisant appel au procédé de surmoulage bien connu d'un insert assurant la rigidité, sans que la matière plastique surmoulée y contribue beaucoup. This is generally the combination of a metal insert and a plastics material filled with glass fibers, using the well-known overmoulding process of an insert providing rigidity, without the overmoulded plastic material contributing to it. a lot.
On connaît déjà, par les brevets français 2 791 297 et 2 803 241, un procédé et une technologie de réalisation d'articles mixtes, comprenant un élément rigide de forme généralement allongée, dont au moins une partie présente une section transversale ayant un profil définissant un espace concave, combiné à une partie en matière thermoplastique positionnée dans le dit espace concave de l'élément rigide, comportant au moins un creux dans sa section transversale. Le procédé utilisé consistant à disposer l'élément rigide dans un moule d'injection de forme appropriée, à injecter la matière thermoplastique fondue dans le moule, et à injecter simultanément un fluide liquide ou gazeux par une aiguille dans la dite matière présente dans l'espace concave de l'élément rigide, en utilisant un French Pat. Nos. 2,791,297 and 2,803,241 disclose a method and a technology for producing mixed articles, comprising a rigid element of generally elongate shape, at least a portion of which has a cross section having a profile defining a concave space, combined with a portion of thermoplastic material positioned in said concave space of the rigid member, having at least one recess in its cross section. The method used consisting in arranging the rigid element in an appropriately shaped injection mold, injecting the molten thermoplastic into the mold, and simultaneously injecting a liquid or gaseous fluid with a needle into the said material present in the mold. concave space of the rigid element, using a
2 procédé d'injection assistée par un fluide liquide ou gazeux sous pression, plus communément appelé, par les hommes de métier, par les initiales de ses termes anglais W.I.T. (Water Injection Technology) ou G.I.T. (Gas Injection Technology). On comprend que, en utilisant cette méthode, après solidification de la matière plastique, celle-ci présente un creux transversal réduisant sa masse, sans réduire notablement son module d'inertie transversal et, par conséquent, sa rigidité. L'élément rigide et les parties en matière thermoplastique étant solidarisés par débordement de la matière thermoplastique à travers des orifices percés dans l'élément rigide. 2 injection method assisted by a liquid or gaseous fluid under pressure, more commonly known by those skilled in the art, by the initials of its English terms W.I.T. (Water Injection Technology) or G.I.T. (Gas Injection Technology). It is understood that, using this method, after solidification of the plastic material, the latter has a transverse hollow reducing its mass, without significantly reducing its transverse modulus of inertia and, consequently, its rigidity. The rigid element and the thermoplastic parts being secured by overflow of the thermoplastic material through holes drilled in the rigid element.
La présente invention a pour but d'adapter ce procédé à la fabrication de pédales et de leviers pour l'industrie automobile, notamment de pédales hybrides plastique métal, et tout particulièrement de pédales de frein. The present invention aims to adapt this method to the manufacture of pedals and levers for the automotive industry, including hybrid metal plastic pedals, and especially brake pedals.
Cette invention, telle qu'elle se caractérise, résout donc le problème consistant à définir un procédé et des méthodes avec lesquels, d'une part, un gain de masse conséquent des pédales ou des leviers puisse être obtenu en utilisant des inserts métalliques de faible épaisseur, dont le manque de rigidité soit compensé par son surmoulage avec une forme plastique creuse, et, d'autre part, un gain économique important soit obtenu. This invention, as it is characterized, thus solves the problem of defining a method and methods with which, on the one hand, a consequent mass gain of the pedals or levers can be obtained by using low metal inserts. thickness, the lack of rigidity is offset by its overmolding with a hollow plastic form, and, secondly, a significant economic gain is obtained.
Le procédé de fabrication de pédales et de leviers hybrides pour l'industrie automobile, utilisant l'association d'un insert métallique et d'une matière plastique par surmoulage du dit insert par injection assistée par un fluide sous pression, avec obtention d'un creux transversal réduisant la masse de l'ensemble, se caractérise en ce qu'il consiste, pour l'essentiel, à effectuer successivement les étapes suivantes : The method of manufacturing pedals and hybrid levers for the automotive industry, using the combination of a metal insert and a plastic material by overmolding said insert by injection assisted by a fluid under pressure, with obtaining a transverse hollow reducing the mass of the assembly, is characterized in that it consists, in essence, in successively performing the following steps:

As shown in particular in FIGS. , 6 and 8, the portion located at the L-shaped return 22 of the metal insert 21 may be overmoulded and also reinforced by plastic ribs 234, inwardly as well as outwardly of the L-shaped portion 22 of the insert 21. The brake rod ball cage holder is also overmolded on the L-shaped return 22 of the metal insert 21. As shown in FIG. 8, it is quite possible to terminate the hollow portion, due to to the injection of water in the upper part of the pedal 20, and to reinforce this same upper part by the addition of ribs 235.
Sur les figures 10 à 15, correspondant à la pédale hybride à transmission déportée 30 d'accroche de la tige de commande, à double insert en U, on remarque que l'insert est constitué de deux parties en U 31 et 32, comportant chacune, à leur extrémité supérieure, côté axe d'articulation, une partie en L 311, 321 destinée à l'encastrement de ces parties l'une dans l'autre, pour obtenir un profil en U par soudage au niveau de leur zone de chevauchement, destiné à recevoir, lors du surmoulage, un boîtier d'articulation 33 se prolongeant vers l'extrémité libre de la petite partie en U 32 pour former le support de cage de rotule de tige de frein 34, comme le montre la figure 12. Comme le montre les figures 14 et 15, les parties constituant l'insert métallique 31, 32 peuvent être rigidifiées par des nervures en matière plastique, à l'extérieur comme à l'intérieur de ces parties. In FIGS. 10 to 15, corresponding to the hybrid pedal with remote transmission 30 for hooking up the control rod, with a double U-shaped insert, it should be noted that the insert consists of two U-shaped parts 31 and 32, each comprising , at their upper end, on the hinge pin side, an L-shaped portion 311, 321 intended for embedding these parts one inside the other, to obtain a U-profile by welding at their overlapping zone. , intended to receive, during overmolding, a hinge housing 33 extending towards the free end of the small U-shaped portion 32 to form the brake rod ball cage support 34, as shown in FIG. 12. As shown in Figures 14 and 15, the parts constituting the metal insert 31, 32 may be stiffened by plastic ribs, outside as well as inside these parts.
Comme pour la pédale simple 10 de la figure 1, l'insert métallique 31, 32 est pourvu de trous 310, 320 ayant pour rôle de solidariser la partie métallique à la partie surmoulée. As for the simple pedal 10 of Figure 1, the metal insert 31, 32 is provided with holes 310, 320 whose role is to secure the metal portion to the overmolded portion.
Ainsi que représenté à la figure 15, l'injection d'eau, permettant de repousser la matière plastique à l'intérieur de l'espace qui lui est laissé, se fait par un point unique 330, commun aux deux canaux. As shown in Figure 15, the injection of water, to push the plastic within the space that is left to him, is by a single point 330, common to both channels.
On remarque, toujours sur la figure 15, qu'il est possible de terminer la zone d'injection d'eau au niveau du plan de jonction AA des deux parties en U 31 et 32 de l'insert, en renforçant ensuite la pièce par ajout de nervures 331, après la limite AA de la zone d'injection d'eau. It is noted, again in FIG. 15, that it is possible to terminate the water injection zone at the junction plane AA of the two U-shaped portions 31 and 32 of the insert, thereby reinforcing the piece by addition of ribs 331 after the AA limit of the water injection zone.
Il n'a été utilisé, dans les exemples donnés, que des inserts profilés en U et en L, mais il est évident. que des inserts d'autres profils, tels qu'en T par exemple, peuvent être aussi utilisés, sous réserve uniquement qu'ils présentent une concavité latérale suffisante pour se prêter à leur surmoulage avec injection d'eau, en réalisant un creux transversal suffisant dans la matière plastique pour réduire sa masse sans compromettre la rigidité de l'ensemble.20 It has been used in the examples given only U-shaped inserts and L, but it is obvious. that inserts other profiles, such as T for example, can also be used, provided only that they have a lateral concavity sufficient to lend themselves to overmolding with water injection, achieving a sufficient transverse hollow in the plastic to reduce its mass without compromising the rigidity of the whole.
