D'APRES CE PROCEDE, ON COULE LE COMPOSANT SELON LA METHODE DE MOULAGE EN CARAPACE. LE COMPOSANT PEUT ETRE CONSTITUE NOTAMMENT PAR LA PIECE PRINCIPALE DE LA COLONNE DE DIRECTION, PAR UN TUBE COULISSANT PORTANT A UNE EXTREMITE LES BRAS 1 D'UNE FOURCHE DE JOINT UNIVERSEL ET PRESENTANT INTERIEUREMENT DES CANNELURES 2 FORMEES PAR BROCHAGE A LA SUITE DE LA COULEE, OU PAR UN ADAPTATEUR ENTRANT DANS UNE TELLE COLONNE DE DIRECTION.ACCORDING TO THIS PROCESS, THE COMPONENT IS CAST ACCORDING TO THE SHELL MOLDING METHOD. THE COMPONENT MAY BE CONSTITUTED IN PARTICULAR BY THE MAIN PART OF THE STEERING COLUMN, BY A SLIDING TUBE CARRYING AT ONE END THE ARMS 1 OF A UNIVERSAL GASKET FORK AND INTERNALLY PRESENTING RIBBLES 2 SHAPED BY PINCHING FOLLOWING THE CASTING, OR BY AN ADAPTER ENTERING SUCH A STEERING COLUMN.
Description
Jusqu'à présent, Les pièces de colonnes de direction, telles que desSo far, parts of steering columns, such as
joints universels, des fourches et adaptateurs pour ces joints et des tubes canneles, sont produites par forgeage ou emboutissage. De telles pièces ont également été fabriquées par moulage en sable classique. Ces procédés connus demandent généralement toute une série d'usinages après le forgeage ou la coulée. L'emboutissage implique des coûts élevés pour l'outillage et la matière. Par exemple, dans le cas d'une fourche et d'un adaptateur pour un joint universel, 10 utilisable notamment dans une colonne de direction à joints universels et à coulissementpermettant divers réglages de position du volant, il faut usiner plusieurs trous, tels que celui devant recevoir l'extrémité d'un tube cannelé, un trou pour un boulon de universal joints, forks and adapters for these joints and grooved tubes, are produced by forging or stamping. Such parts have also been produced by conventional sand molding. These known methods generally require a whole series of machining operations after forging or casting. Stamping involves high costs for tooling and material. For example, in the case of a fork and an adapter for a universal joint, usable in particular in a steering column with universal joints and sliding allowing various adjustments of position of the steering wheel, it is necessary to machine several holes, such as that to receive the end of a grooved tube, a hole for a bolt
serrage, de même qu'une fente pour ce boulon. tightening, as well as a slot for this bolt.
Un arbre de direction classique pour camion est habituellement réalisé sous forme d'un tube forgé avec un alésagecannelé obtenu A conventional steering shaft for a truck is usually made in the form of a forged tube with a channeled bore obtained
par usinage dans la masse.by mass machining.
L'un des buts de la présente invention est de faciliter la fabrication des composants décrits ci-dessus, avec un minimum One of the aims of the present invention is to facilitate the manufacture of the components described above, with a minimum
d'usinages et en utilisant des modèles d'un coût relativement bas. and using relatively low cost models.
Un procédé qui n'a pas encore été essayé jusqu'à présent, pour ce qui concerne la fabrication des composants indiqués cidessus, est le procédé de moulage en carapace, selon lequel on forme un moule réfractaire rigide, poreux et autoporteur par mou25 lage de sable, mélangé avec des matières plastiques ou une résine thermodurcissables, dans un modèle métallique préchauffé, suivi A process which has not yet been tried so far, with regard to the manufacture of the components indicated above, is the shell molding process, according to which a rigid, porous and self-supporting refractory mold is formed by molding of sand, mixed with plastics or thermosetting resin, in a preheated metallic model, followed
d'un durcissement complet par polymérisation. complete curing by polymerization.
La présente invention apporte par conséquent un procédé pour fabriquer un composant d'une colonne de direction de véhicule, qui 30 consiste à produire le composant par coulée, en utilisant un procédé The present invention therefore provides a method for manufacturing a component of a vehicle steering column, which comprises producing the component by casting, using a method
de moulage en carapace.shell molding.
Les produits auxquels ce procédé de fabrication est applicable sont, notamment, la colonne de direction elle-même, un joint universel ou joint de cardan pour une colonne de direction, une four35 che pour un tel joint, ainsi qu'un adaptateur destiné à être utilisé 15 '25 35 The products to which this manufacturing process is applicable are, in particular, the steering column itself, a universal joint or universal joint for a steering column, a fork 35 for such a joint, as well as an adapter intended to be used 15 '25 35
sur un accouplement en caoutchouc pour un tel joint. La colonne de direction produite par le procédé selon l'invention peut se présenter également sous forme d'un tube cannelé. on a rubber coupling for such a seal. The steering column produced by the method according to the invention can also be in the form of a grooved tube.
Afin de mieux faire comprendre l'invention et pour montrer de quelle manière elle peut être mise en oeuvre, il y a lieu de se référer, pour la description qui va suivre, donnée à titre d'exemple, au dessin annexé, sur lequel: In order to better understand the invention and to show how it can be implemented, reference should be made, for the description which follows, given by way of example, to the appended drawing, in which:
- la figure 1 est une vue de côté d'un tube coulissant d'une colonne de direction; - la figure 2 est une coupe axiale partielle du tube de figure 1; - la figure 3 est la vue de côté de la fourche d'un joint universel faisant partie d'une colonne de direction; - la figure 4 est une vue en bout de la fourche de figure 3; - la figure 5 est une vue en bout d'un adaptateur de la colonne de direction; et - Figure 1 is a side view of a sliding tube of a steering column; - Figure 2 is a partial axial section of the tube of Figure 1; - Figure 3 is the side view of the fork of a universal joint forming part of a steering column; - Figure 4 is an end view of the fork of Figure 3; - Figure 5 is an end view of an adapter of the steering column; and
- la figure 6 est une vue en plan de cet adaptateur. - Figure 6 is a plan view of this adapter.
Les figures 1 et 2 montrent un tube coulissant qui a été coulé selon le procédé de moulage en carapace. Deux bras d'une fourche 1, faisant partie d'un joint universel, sont formés d'un seul tenant, lors du moulage, à une extrémité du tube. Après la coulée, il suffit de réaliser, par brochage, des cannelures 2 à développante pour compléter l'alésage cannelé. Figures 1 and 2 show a sliding tube which was cast using the shell molding process. Two arms of a fork 1, forming part of a universal joint, are formed in one piece, during molding, at one end of the tube. After casting, it suffices to make, by broaching, involute grooves 2 to complete the grooved bore.
Les figures 3 et 4 montrent une fourche de joint universel et les figures 5 et 6 montrent un adaptateur pour une application typique à un arbre de direction.Cette fourche et cet adaptateur sont également coulés selon le procédé de moulage en carapace, avec formation, lors du moulage, d'un trou -pré-dentelé 3 dans la fourche, de même que, à la fois dans la fourche et dans l'adaptateur, d'un trou 4 et d'une fente 5 pour un boulon de serrage. Les trous 3 et 4 et la fente 5 doivent être usinés ensuite selon des procédés classiques, mais il y a de nombreuses autres surfaces, sur toutes les pièces illustrées, qu!il n'est plus nécessaire d'usiner à la suite de la coulée en carapace, alors qu'un tel usinage était nécessaire selon les procédés conventionnels. Figures 3 and 4 show a universal joint fork and Figures 5 and 6 show an adapter for a typical application to a steering shaft. This fork and this adapter are also cast using the shell molding process, with formation, during molding, a pre-serrated hole 3 in the fork, as well as, both in the fork and in the adapter, a hole 4 and a slot 5 for a tightening bolt. The holes 3 and 4 and the slot 5 must then be machined according to conventional methods, but there are many other surfaces, on all of the parts illustrated, which it is no longer necessary to machine after casting. in shell, while such machining was necessary according to conventional methods.
Le procédé de fabrication selon L'invention est applicable aussi à des composants de colonnes de direction qui ne doivent pas être produits en grandes quantités puisque Les modèles employés pour le moulage sont relativement bon marché. The manufacturing method according to the invention is also applicable to components of steering columns which must not be produced in large quantities since the models used for molding are relatively inexpensive.
