Abstract

Component with two assembled shells making it possible to accommodate a threaded or smooth rod. This component is simpler and less expensive than an undercut component with a blind hole on one side and squashed and drilled on the other. This component can also be made of a single piece. This component has the particular feature of being able to accommodate a tapped knurled sleeve allowing very accurate adjustment (no more problem of the half turn) of the pressure switch. This adjustment operation can also be carried out in the case of the pressure switch assembled on the turbo. Reduction in fitting time, precision therefore considerably lowered cost. The other advantages for the two examples are that the materials used for these components can be of different types, as can be coatings and surface treatments.

Description

La présente invention concerne un dispositif permettant de relier de façon rigide un pressostat à une soupape d'échappement de gaz, notamment pour les turbocompresseurs de moteur à combustion. The present invention relates to a device for rigidly connecting a pressure switch to a gas exhaust valve, in particular for combustion engine turbochargers.

Actuellement, les turbos sont équipés soit - d'une tige monobloc reliant directement le pressostat à la partie soupape sans réglage possible. Currently, turbos are fitted with either - a monobloc rod directly connecting the pressure switch to the valve part without possible adjustment.

- d'un axe décolleté, percé, taraudé à une extrêmité et écrasé, percé de l'autre assurant la liaison tige du pressostat et soupape d'échappement des gaz, avec réglage possible par demi tour.- a neckline axis, drilled, tapped at one end and crushed, drilled on the other ensuring the connection between the pressure switch rod and the gas exhaust valve, with adjustment possible by half turn.

Les dispositifs ci-dessus présentent les inconvénients suivants - La tige monobloc doit avoir deux duretés différentes : une dureté faible côté pressostat pour permettre son assemblage par sertissage, et une dureté importante de l'autre extrêmité écrasée, percée car il y a un mouvement permanent sous pression.The above devices have the following drawbacks - The monobloc rod must have two different hardnesses: a low hardness on the pressure switch side to allow its assembly by crimping, and a high hardness on the other end crushed, pierced because there is a permanent movement under pressure.

Si cette partie n'est pas dure, un jeu peut se produire et entraîner un déréglage de la régulation.If this part is not hard, a game can occur and cause an adjustment of the regulation.

- Pour l'axe décolleté, le réglage fin n'est pas possible, il est d'un demi tour minimum car la partie écrasée, percée doit rentrer dans l'axe de la pièce liée à la soupape d'échappement.- For the neckline axis, fine adjustment is not possible, it is a minimum of half a turn because the crushed, pierced part must enter the axis of the part linked to the exhaust valve.

La présente invention vise à supprimer ces inconvénients, elle permet en effet d'obtenir les résultats suivants - Dans le cas d'une tige monobloc, la tige sera non traitée à l'extrêmité dun pressostat donc dureté faible permettant le sertissage et l'autre bout de la partie soudée pourra être traité dur pour éviter la prise de jeu côté soupape d'échappement.The present invention aims to eliminate these drawbacks, it in fact makes it possible to obtain the following results - In the case of a monobloc rod, the rod will be untreated at the end of a pressure switch therefore low hardness allowing crimping and the other the end of the welded part can be treated hard to avoid backlash on the exhaust valve side.

- Dans l'autre cas, la molette dans laquelle vient se loger la tige filetée permet un réglage fin et une rapidité de montage donc coût moins élevé.- In the other case, the wheel in which is housed the threaded rod allows fine adjustment and speed of assembly therefore lower cost.

Cette présente invention permet d'obtenir un prix de revient pièce d'environ 40 % inférieur au prix actuel.This present invention makes it possible to obtain a part cost price of approximately 40% lower than the current price.

Les moyens mis en oeuvre pour obtenir ces résultats sont les suivants - Dans le premier cas, la tige monobloc est en deux parties.The means used to obtain these results are as follows - In the first case, the one-piece rod is in two parts.

Première partie corps composée de deux demi-coquilles assemblées par soudage ou sertissage comprenant chacune une demi-lune devenant après assemblage un trou lisse servant à recevoir une partie de la tige maintenue par soudage électrique. First body part composed of two half-shells assembled by welding or crimping each comprising a half-moon becoming after assembly a smooth hole used to receive a part of the rod held by electric welding.

Les deux demi-lunes forment un trou. Ce trou peut être taraudé et recevoir une tige filetée permettant le réglage de la régulation mais, comme dans la version actuelle, le problème reste le demi-tour obligatoire donc manque de réglage fin.The two half-moons form a hole. This hole can be tapped and receive a threaded rod allowing the regulation to be adjusted, but, as in the current version, the problem remains the compulsory U-turn therefore lack of fine adjustment.

- Dans le second cas, les deux parties du corps assemblées peuvent recevoir une molette taraudée permettant un réglage fin du pressostat en agissant sur la longueur de la tige filetée pénétrant plus ou moins dans la molette ; un autre avantage important est que le réglage fin peut se faire une fois le pressostat monté et assemblé par son circlips.- In the second case, the two parts of the assembled body can receive a threaded knob allowing fine adjustment of the pressure switch by acting on the length of the threaded rod penetrating more or less into the knob; another important advantage is that the fine adjustment can be done once the pressure switch is mounted and assembled by its circlip.

Cette pièce peut être réalisée de différentes manières, soit par découpage/emboutissage, soit par fonderie, soit par usinage en deux coquilles ou monobloc. This part can be produced in different ways, either by cutting / stamping, or by foundry, or by machining in two shells or in one piece.

A titre d'exemples non limitatifs, on va décrire, ci-dessous, des modes de réalisation du dispositif selon l'invention.: - Exemple 1 : Corps (1) composé de deux parties (2) et (3) embouties et solidarisées entre elles, comportant des enfoncements en demi-lune (5) déterminant un trou (4) taraudé et pouvant recevoir l'extrêmité (6) de la tige filetée solidaire du pressostat. As nonlimiting examples, we will describe, below, embodiments of the device according to the invention: - Example 1: Body (1) composed of two parts (2) and (3) stamped and secured between them, comprising half-moon recesses (5) determining a tapped hole (4) which can receive the end (6) of the threaded rod secured to the pressure switch.

Le réglage étant obtenu par rotation de la pièce (1).The adjustment being obtained by rotation of the part (1).

L'inconvénient est que le réglage ne peut se faire que par demitour, du fait que la pièce (1) doit être solidaire de la commande de la soupape par l'intermédiaire d'un axe (13) qui pénètre à l'intérieur du trou (7) dasn lequel il est maintenu par un circlips (14).The disadvantage is that the adjustment can only be made by half-turn, since the part (1) must be integral with the control of the valve by means of an axis (13) which penetrates inside the hole (7) in which it is held by a circlip (14).

- Exemple 2 : Le dispositif est semblable à celui de l'exemple 1 sauf que le trou (4) est lisse et peut recevoir une tige non filetée fixée par soudage.- Example 2: The device is similar to that of Example 1 except that the hole (4) is smooth and can receive a non-threaded rod fixed by welding.

Les pièces selon l'exemple 1 ou l'exemple 2 sont moins coûteuses qu'une pièce décolletée avec un trou borgne d'un côté et écrasé, percé de l'autre.The parts according to Example 1 or Example 2 are less expensive than a low-cut part with a blind hole on one side and crushed, drilled on the other.

- Exemple 3 : Le trou fileté (4) est remplacé par la molette (10) dans laquelle on inttroduit la tige filetée (6). La tige filetée pénètre à l'intérieur du dispositif par le trou (11) qui est lisse et ensuite pénètre à l'intérieur de la molette. La rotation de la molette permet d'agir sur la longueur de l'ensemble ; un trou (12) est prévu pour recevoir l'autre extrêmité (8) de la molette. L'autre extrêmité (9) pénètre dans le trou (11).- Example 3: The threaded hole (4) is replaced by the thumbwheel (10) into which the threaded rod (6) is introduced. The threaded rod penetrates inside the device through the hole (11) which is smooth and then penetrates inside the wheel. The rotation of the wheel makes it possible to act on the length of the assembly; a hole (12) is provided for receiving the other end (8) of the wheel. The other end (9) enters the hole (11).

Le réglage, très précis, est obtenu par rotation de la molette (10) (plus de problème de demi-tour). Il peut être fait turbo assemblé, d'où réduction des temps de montage, meilleure précision, prix réduit considérablement.The very precise adjustment is obtained by rotating the dial (10) (no more U-turn problem). It can be made turbo assembled, hence reduction of assembly times, better precision, considerably reduced price.

Les autres avantages pour les trois exemples sont que les matériaux utilisés pour ces pièces peuvent être de différents types, ainsi que les révêtements et traitements de surfaces. The other advantages for the three examples are that the materials used for these parts can be of different types, as well as the coatings and surface treatments.
