Description

CARTER COMPRESSEUR A PALIER RELAIS INTEGRE. L'invention concerne le domaine des turbocompresseurs. L'invention concerne en particulier un carter compresseur à palier relais intégré pour turbocompresseur. COMPRESSOR CASING WITH INTEGRATED RELAY. The invention relates to the field of turbochargers. In particular, the invention relates to an integrated bearing compressor compressor housing for a turbocharger.

La plupart des véhicules comportant un groupe motopropulseur transversal comportent une boîte qui est accolée d'un côté du moteur et dont un pont entraîne les roues du véhicule par l'intermédiaire de deux arbres de transmission de longueur différente. Un arbre de transmission court relie un différentiel intégré à la boite à une roue, tandis qu'un arbre de transmission long, qui s'étend en partie sous le moteur du véhicule, relie le différentiel à l'autre roue. Most vehicles with a transverse powertrain have a box that is contiguous to one side of the engine and a bridge drives the wheels of the vehicle through two transmission shafts of different lengths. A short transmission shaft connects a differential built into the gearbox to a wheel, while a long drive shaft, which extends in part under the engine of the vehicle, connects the differential to the other wheel.

Cet arbre de transmission long pose de nombreux problèmes de flexion et de torsion lors du fonctionnement du groupe motopropulseur. Il est de plus sujet à de nombreuses vibrations. Pour remédier à cet inconvénient, on a proposé de soutenir et de guider en rotation le demi-arbre aval de l'arbre de transmission long par l'intermédiaire d'un palier dit "palier relais" qui est fixé au bloc du moteur. Cette configuration permet d'assurer une reprise des efforts de flexion de l'arbre de transmission long sur le bloc moteur, et par conséquent d'améliorer le comportement et la fiabilité de l'arbre de transmission long. Conventionnellement, le palier relais est fixé sur le bloc moteur par l'intermédiaire d'une chape en deux parties. Un tel palier relais est décrit dans le document FR-2876630. - 2 L'implantation d'un palier relais tel que décrit dans le document FR-2876630 dans un compartiment moteur d'un véhicule automobile pose problème. En effet, cet organe mécanique est consommateur d'espace et, la complexité de l'architecture des compartiments moteur augmentant, il faut disposer de plus en plus d'éléments dans un espace de plus en plus réduit. This long drive shaft poses many bending and twisting problems during the operation of the power train. It is also subject to many vibrations. To overcome this drawback, it has been proposed to support and guide in rotation the downstream half-shaft of the long transmission shaft via a so-called "relay bearing" bearing which is fixed to the engine block. This configuration makes it possible to ensure a recovery of the bending forces of the long drive shaft on the engine block, and consequently to improve the behavior and reliability of the long drive shaft. Conventionally, the relay bearing is fixed on the engine block by means of a two-part clevis. Such a relay bearing is described in the document FR-2876630. The implementation of a relay bearing as described in document FR-2876630 in an engine compartment of a motor vehicle is problematic. Indeed, this mechanical member is space-consuming and, the complexity of the architecture of engine compartments increasing, it is necessary to have more and more elements in a space increasingly reduced.

Un but de l'invention est de résoudre les problèmes de l'art antérieur, en fournissant une solution de soutien et de guidage en rotation d'un arbre de transmission long plus compacte. A cet effet, la présente invention propose un carter compresseur pour turbocompresseur caractérisé en ce qu'il comporte un palier relais destiné à recevoir un arbre de transmission d'un groupe motopropulseur. An object of the invention is to solve the problems of the prior art by providing a solution for supporting and guiding the rotation of a longer, more compact transmission shaft. For this purpose, the present invention proposes a turbocharger compressor housing characterized in that it comprises a relay bearing for receiving a transmission shaft of a powertrain.

15 Le carter compresseur et le palier relais forment alors une seule pièce, ce qui permet un important gain d'espace dans un compartiment moteur d'un véhicule automobile. The compressor housing and the relay bearing then form a single piece, which allows a significant space saving in a motor compartment of a motor vehicle.

Selon d'autres caractéristiques de la présente invention prises séparément ou 20 en combinaison : • le palier relais s'étend à partir d'une paroi externe du carter compresseur, • le palier relais s'étend radialement par rapport à l'axe du carter compresseur à partir de la paroi axiale externe du carter compresseur, 25 • le carter compresseur et le palier sont réalisés par moulage d'un alliage d'aluminium,10 - 3 • le palier relais comporte une portion intermédiaire de maintien au carter compresseur, la portion intermédiaire s'étendant axialement et radialement sur un portion de la paroi externe du carter compresseur, • le pallier relais comporte une portion circulaire comportant à une de ses extrémités un pivot sur lequel est articulé un collier de serrage, • le collier de serrage est en portion de cercle et comporte une extrémité taraudée destinée à coopérer avec une vis de serrage, • le palier relais comporte une plaque de fixation destinée à coopérer avec une paroi d'un bloc moteur d'un moteur à combustion interne. 10 L'invention propose également un turbocompresseur comportant un carter compresseur tel que défini ci-dessus. According to other features of the present invention taken separately or in combination: the relay bearing extends from an outer wall of the compressor housing; the relay bearing extends radially with respect to the axis of the housing; compressor from the outer axial wall of the compressor housing, 25 • the compressor housing and the bearing are made by molding an aluminum alloy, 10 - 3 • the relay bearing comprises an intermediate portion for maintaining the compressor housing, the intermediate portion extending axially and radially on a portion of the outer wall of the compressor housing, • the relay stage comprises a circular portion having at one of its ends a pivot on which is articulated a clamping collar, • the clamping collar is in a portion of a circle and comprising a threaded end intended to cooperate with a clamping screw, the relay bearing comprises a fixing plate intended to operate with a wall of an engine block of an internal combustion engine. The invention also proposes a turbocharger comprising a compressor casing as defined above.

L'invention propose enfin un groupe motopropulseur comportant un 15 turbocompresseur tel que défini ci-dessus. The invention finally proposes a power unit comprising a turbocharger as defined above.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture d'un mode de réalisation détaillé, non limitatif, faite en référence aux figures annexées sur lesquelles: Other characteristics and advantages of the present invention will become apparent on reading a detailed, nonlimiting embodiment, with reference to the appended figures in which:

la figure 1 est une vue en perspective d'un turbocompresseur comportant un carter compresseur selon l'invention, - la figure 2 est une vue de droite, coté carter turbo, de la figure 1, - la figure 3 est une vue de dessus de la figure 1. FIG. 1 is a perspective view of a turbocharger comprising a compressor crankcase according to the invention; FIG. 2 is a right view, on the turbo crankcase side, of FIG. 1; FIG. 3 is a top view of FIG. Figure 1.

On se reporte aux figures 1 à 3. On a représenté un turbocompresseur 3 comportant un carter turbo 5 et un carter compresseur 7 de forme cylindrique d'axe A (visible sur la figure 3). Le carter turbo 3 comporte une bride 9 pour 20 25 -4 sa fixation à un collecteur d'échappement d'un moteur à combustion interne. Le carter compresseur 7 comporte une paroi radiale externe 7a et une paroi axiale externe 7b et un conduit 11 d'amenée d'air frais à comprimer. Le carter compresseur 7 comporte également un conduit 15 d'amenée d'air frais comprimé vers l'admission d'un moteur à combustion interne. Referring to Figures 1 to 3. There is shown a turbocharger 3 having a turbo casing 5 and a compressor casing 7 of cylindrical shape of axis A (visible in Figure 3). The turbo housing 3 has a flange 9 for 20 25 -4 attachment to an exhaust manifold of an internal combustion engine. The compressor casing 7 comprises an outer radial wall 7a and an outer axial wall 7b and a duct 11 for supplying fresh air to be compressed. The compressor casing 7 also comprises a duct 15 for supplying fresh compressed air to the intake of an internal combustion engine.

Le carter compresseur comporte en outre un palier relais 13, destiné à recevoir un arbre de transmission long en provenance d'une boîte de vitesse d'un groupe motopropulseur. Le carter compresseur 7 et le palier relais 13 peuvent être réalisés par moulage d'un alliage d'aluminium et forment ainsi une seule pièce. The compressor housing further comprises a relay bearing 13, for receiving a long transmission shaft from a gearbox of a powertrain. The compressor housing 7 and the relay bearing 13 can be made by molding an aluminum alloy and thus form a single piece.

Le palier relais 13 est solidaire de la paroi axiale externe 7b du carter compresseur, et s'étend radialement par rapport à l'axe A du carter compresseur dans la direction opposée à celle de l'implantation du conduit 15. Plus précisément, le palier relais 13 comporte une portion intermédiaire 21 de maintien au carter compresseur, s'étendant axialement et radialement par rapport à l'axe A sur un portion de la paroi externe 7b du carter compresseur. The relay bearing 13 is integral with the outer axial wall 7b of the compressor casing, and extends radially with respect to the axis A of the compressor casing in the direction opposite to that of the implantation of the duct 15. More specifically, the bearing relay 13 comprises an intermediate portion 21 for maintaining the compressor housing, extending axially and radially with respect to the axis A on a portion of the outer wall 7b of the compressor housing.

Le palier 13 comporte une plaque de fixation 17 destinée à coopérer avec une paroi d'un bloc moteur d'un moteur à combustion interne. Le socle de fixation 17 définit des trous taraudés 19 de réception de vis de fixation (non représentées sur les figures) du palier relais 13 à la paroi du bloc moteur. Le pallier relais comporte une portion circulaire 22 comportant à une de ses extrémités un pivot 23 sur lequel est articulé un collier de serrage 27. Le collier de serrage 27 est également en portion de cercle et comporte une extrémité taraudée destinée à coopérer avec une vis de serrage 25. La vis de25 -5 serrage 25 coopère également avec un trou taraudé défini dans la portion circulaire 22. La portion circulaire 22 et le collier de serrage 27 définissent un passage 29 destiné à recevoir l'arbre de transmission. Plus précisément le passage 29 est destiné à recevoir un roulement à bille recevant lui-même l'arbre de transmission. La portion circulaire 22 et le collier de serrage 27 s'étendent dans un plan perpendiculaire au socle 17. The bearing 13 comprises a fixing plate 17 intended to cooperate with a wall of an engine block of an internal combustion engine. The mounting base 17 defines tapped holes 19 for receiving fixing screws (not shown in the figures) from the relay bearing 13 to the wall of the motor unit. The relay stage comprises a circular portion 22 having at one of its ends a pivot 23 on which is articulated a clamping collar 27. The clamping collar 27 is also in a portion of a circle and has a threaded end intended to cooperate with a screw of 25. The clamping screw 25 also cooperates with a threaded hole defined in the circular portion 22. The circular portion 22 and the clamp 27 define a passage 29 for receiving the drive shaft. More precisely, the passage 29 is intended to receive a ball bearing which itself receives the transmission shaft. The circular portion 22 and the clamping collar 27 extend in a plane perpendicular to the base 17.

Le palier relais 13 comporte également une portion de liaison 31 du socle 17 à la portion circulaire 21. Une nervure de renfort triangulaire 33 s'étend entre le socle 17 et la portion intermédiaire 21. The relay bearing 13 also comprises a connecting portion 31 of the base 17 to the circular portion 21. A triangular reinforcing rib 33 extends between the base 17 and the intermediate portion 21.

Selon l'invention, le carter compresseur et le palier relais forment une unique pièce qui a pour avantage d'occuper un espace restreint dans le compartiment moteur d'un véhicule automobile.15 According to the invention, the compressor housing and the relay bearing form a single piece which has the advantage of occupying a small space in the engine compartment of a motor vehicle.
