Abstract

The guide rail consists of a main body (12) and an anti-friction coating (13) which are moulded together by a bi-component injection process so that once they have set they are fixed together. The material which forms the body is injected into the mould first, followed immediately afterwards by the coating material. The material forming the body ( 32) is a plastic with reinforcing additives, for example, a polyamide reinforced with glass fibres, while the outer coating is another plastic which is resistant to abrasion.

Description

Etat de la technique. State of the art.

L'invention concerne un rail de guidage, notamment un rail tendeur pour un entraînement par arbre à cames d'un moteur à combustion interne, comprenant un corps de base et un corps de revêtement glissant formé sur le corps de base pour guider la chaîne de commande. The invention relates to a guide rail, in particular a tensioning rail for a camshaft drive of an internal combustion engine, comprising a base body and a sliding covering body formed on the base body to guide the chain. ordered.

Les rails de guidage correspondant à ce type servent à guider et à tendre les chaînes et autres moyens d'entraînement des arbres à cames ou équipements accessoires de véhicules automobiles. C'est pourquoi les rails de guidage doivent pouvoir résister aux contraintes énormes exercées par une chaîne. The guide rails corresponding to this type are used to guide and tension the chains and other means of driving the camshafts or accessory equipment of motor vehicles. This is why the guide rails must be able to withstand the enormous stresses exerted by a chain.

Selon le document DE-A-37 06 136, il est connu de réaliser le rail tendeur avec un corps de base et un corps de revêtement glissant tenu par le corps de base. Le revêtement glissant est relié au corps de base par une liaison par la force et par la forme s'étendant dans la direction de circulation de la chaîne. According to document DE-A-37 06 136, it is known to produce the tensioning rail with a base body and a sliding covering body held by the base body. The sliding covering is connected to the base body by a connection by force and by the form extending in the direction of movement of the chain.

Avantages de l'invention. Advantages of the invention.

La présente invention concerne ainsi un rail de guidage correspondant au type défini ci-dessus, caractérisé en ce que les matières du corps de base et du corps de revêtement glissant sont appliquées l'une sur l'autre à l'état fondu pour que lorsque les deux matières se solidifient, il se réalise une liaison par la matière entre le corps de base et le corps de revêtement glissant. The present invention thus relates to a guide rail corresponding to the type defined above, characterized in that the materials of the base body and of the sliding coating body are applied to each other in the molten state so that when the two materials solidify, a bond is made by the material between the base body and the sliding coating body.

Ce rail de guidage offre l'avantage d'être réalisable en totalité au cours d'une seule opération. La solidification simultanée des deux matières du corps de base et du corps constituant le corps de revêtement glissant constitue une liaison par la matière entre ces deux corps. This guide rail offers the advantage of being entirely achievable in a single operation. The simultaneous solidification of the two materials of the base body and of the body constituting the sliding coating body constitutes a connection by the material between these two bodies.

Selon une autre caractéristique il est particulièrement avantageux que le rail de guidage soit fabriqué selon un procédé d'injection à deux composants. According to another characteristic, it is particularly advantageous for the guide rail to be manufactured according to a two-component injection process.

Si le corps du revêtement glissant présente une forme de U on a un guidage particulièrement bon pour la chaîne de commande.  If the body of the sliding covering has a U shape, there is particularly good guidance for the control chain.

Le fait de limiter la pellicule extérieure, de préférence au corps de revêtement glissant en forme de U, offre l'avantage de ne pas trop affaiblir la solidité du rail de guidage par la matière instable de la pellicule extérieure. Limiting the outer film, preferably to the U-shaped sliding coating body, has the advantage of not weakening the strength of the guide rail too much by the unstable material of the outer film.

De manière complète, suivant des caractéristiques avantageuses
- le corps de base et le corps de revêtement glissant sont réalisés par un procédé d'injection à deux composants, par injection d'abord de la matière constituant le corps de revêtement glissant puis par injection immédiatement après de la matière constituant principalement le corps de base, dans la cavité du moule d'injection
- la matière qui constitue principalement le corps de base forme un coeur et la matière réalisant le corps de revêtement glissant constitue une pellicule entourant au moins partiellement le coeur
- le coeur est en matière plastique avec des additifs de renforcement
- la pellicule extérieure est en une matière plastique résistant à l'abrasion
- le corps de revêtement glissant est en forme de

- la pellicule est principalement réalisée sur le corps de revêtement glissant en forme de U.Completely, according to advantageous characteristics
the base body and the sliding coating body are produced by a two-component injection process, by first injecting the material constituting the sliding coating body and then by injection immediately after the material constituting mainly the base, in the cavity of the injection mold
- the material which mainly constitutes the basic body forms a heart and the material making the sliding coating body constitutes a film at least partially surrounding the heart
- the heart is made of plastic with reinforcing additives
- the outer film is made of an abrasion-resistant plastic
- the sliding covering body is shaped like

Exemple de réalisation. Example of realization.

Les figures 1 et 2 montrent un rail tendeur portant la référence 10 destiné par exemple à une chaîne de commande d'un moteur à combustion interne. Le rail tendeur 10 est formé d'un corps de base 12 et d'un corps de revêtement glissant 13.  Figures 1 and 2 show a tensioning rail bearing the reference 10 intended for example for a control chain of an internal combustion engine. The tensioning rail 10 is formed by a base body 12 and a sliding covering body 13.

Le corps de base 12 possède par exemple une ossature 14 avec un grand nombre d'entretoises 15 donnant la solidité nécessaire au corps de base 12. Un perçage 16 recevant un goujon non représenté est prévu dans le corps de base 12. Le perçage 16 permet de fixer le rail tendeur 10 à un élément non représenté du moteur à combustion interne ; le rail tendeur 10 est monté pivotant sur le goujon non représenté. Un élément de compression, également non représenté, communique au rail tendeur la force antagoniste correspondante pour tendre la chaîne de commande.The base body 12 has for example a frame 14 with a large number of spacers 15 giving the necessary solidity to the base body 12. A hole 16 receiving a stud not shown is provided in the base body 12. The hole 16 allows fixing the tensioning rail 10 to an element (not shown) of the internal combustion engine; the tensioner rail 10 is pivotally mounted on the stud, not shown. A compression element, also not shown, communicates to the tensioning rail the corresponding opposing force for tensioning the control chain.

La direction de circulation de la chaîne de commande est indiquée par la flèche 17.The direction of movement of the control chain is indicated by arrow 17.

Il apparaît selon la figure 1 que le rail tendeur 10 présente une forme courbe. Sur l'arc extérieur du rail tendeur 10 on a formé sur le corps de base 12, le corps de revêtement glissant 13 ; comme le montre la figure 2, ce corps peut par exemple avoir une forme de U. Le corps de revêtement glissant 13, en forme de U, comprend deux branches 22 et un fond 23 pratiquement plan entre les branches 22. Les branches 22 assurent le guidage latéral nécessaire à la chaîne de commande. Le fond 23 constitue la surface d'appui et ainsi la surface de tension pour la chaîne de commande. It appears from Figure 1 that the tensioning rail 10 has a curved shape. On the outer arc of the tensioning rail 10, the sliding covering body 13 has been formed on the base body 12; as shown in FIG. 2, this body can for example have a U shape. The sliding covering body 13, in U shape, comprises two branches 22 and a practically flat bottom 23 between the branches 22. The branches 22 provide the lateral guidance required for the control chain. The bottom 23 constitutes the bearing surface and thus the tension surface for the control chain.

Selon la figure 2, le corps de base 12 se compose d'un coeur 30, par exemple en polyamide renforcé par des fibres de verre. Une pellicule extérieure 32 entoure le coeur 30. According to Figure 2, the base body 12 consists of a core 30, for example of polyamide reinforced with glass fibers. An outer film 32 surrounds the heart 30.

Cette pellicule est par exemple réalisée en un polyamide non renforcé, stabilisé à la chaleur. La matière du coeur 30 a pour but de donner la solidité nécessaire au corps de base 12 et au rail tendeur 10. La pellicule extérieure 32 sert par contre à former au moins le corps de revêtement glissant 13. La matière de la pellicule extérieure 32 doit résister à l'abrasion.This film is for example made of an unreinforced polyamide, heat stabilized. The purpose of the material of the core 30 is to give the necessary strength to the base body 12 and to the tensioning rail 10. The outer film 32, on the other hand, serves to form at least the sliding coating body 13. The material of the outer film 32 must resist abrasion.

La fabrication du rail tendeur 10 se fait selon un procédé dit d'injection à deux composants. Ainsi, on injecte tout d'abord la matière de la peau extérieure 32 dans le moule d'injection. Puis immédiatement on injecte la matière du coeur 30 dans la cavité du moule d'injection. La matière de la pellicule extérieure 32 est poussée à la suite par la matière extrudée dans le moule d'injection, dans les creux et ainsi, en particulier, contre les parois, de sorte que le coeur 30 est au moins entouré sensiblement par la pellicule extérieure 32. Il est important que les deux matières soient injectées directement l'une à la suite de l'autre pour que la matière qui forme la pellicule 32 soit encore fluide lors de l'injection de la matière constituant le coeur 30. Ainsi, lors de la solidification, il se réalise une liaison par la matière entre la matière du coeur 30 et la pellicule 32. Une liaison par la matière utilise les forces moléculaires à l'intérieur des matériaux ou à la surface des matériaux. The tensioner rail 10 is manufactured using a so-called two-component injection process. Thus, the material of the outer skin 32 is first injected into the injection mold. Then immediately the material of the core 30 is injected into the cavity of the injection mold. The material of the outer film 32 is subsequently pushed by the material extruded into the injection mold, into the recesses and thus, in particular, against the walls, so that the heart 30 is at least substantially surrounded by the film exterior 32. It is important that the two materials are injected directly one after the other so that the material which forms the film 32 is still fluid during the injection of the material constituting the core 30. Thus, during solidification, a bond is made by the material between the material of the core 30 and the film 32. A bond by the material uses the molecular forces inside the materials or on the surface of the materials.

On peut envisager, par une mise en forme particulière du moule d'injection et/ou par le choix de certains paramètres d'injection, de concentrer la peau extérieure 32 principalement sur le corps de revêtement glissant 13 en forme de U. Ainsi, la solidité de la matière du coeur 30 du rail tendeur 10 n'est pratiquement pas touchée. One can consider, by a particular shaping of the injection mold and / or by the choice of certain injection parameters, to concentrate the outer skin 32 mainly on the sliding coating body 13 in U shape. solidity of the material of the core 30 of the tensioning rail 10 is practically not affected.

On peut en outre envisager d'autres procédés de fabrication utilisant l'état fondu des deux matières, par exemple le procédé appelé monosandwich .  One can also consider other manufacturing processes using the molten state of the two materials, for example the process called monosandwich.
