Abstract
(DE)
Die Erfindung betrifft einen Verdichter (30) für eine Aufladevorrichtung (1) einer Brennkraftmaschine. Stromaufwärts vordem Verdichterrad (13) ist ein Irisblendenmechanismus (50) angeordnet. Es ist ein Aktuator (61) vorgesehen, der mechanisch mit einem Verstellring (53) des Irisblendenmechanismus (50) zum Übertragen eines Drehmoments einer Aktuatorwelle (62) auf den Verstellring (53) zum Verdrehen des Verstellrings (53) gekoppelt ist. An der Aktuatorwelle (62) ist exzentrisch ein verschwenkbarer Koppelstift (64) angeordnet, der eine entlang einer Längsachse des Koppelstifts (64) verschiebbare Lagerbuchse (66) aufweist. Die Lagerbuchse (66) ist zwischen zwei Fingern (67) eines Stellhebels (53a) des Verstellrings (53) verschiebbar entlang der Finger (67) an den Fingern (67) gelagert. Eine äußere Kontaktoberfläche (71) ist der Lagerbuchse (66) sphärisch ausgebildet. Innere Kontaktoberflächen (72) der beiden Finger (67) sind korrespondierend zu der sphärischen äußeren Kontaktoberfläche (71) der Lagerbuchse (66) zylindrisch ausgebildet und stehen in Gleitkontakt mit der äußeren Kontaktoberfläche (71) der Lagerbuchse (66). Die Erfindung betrifft auch eine Aufladevorrichtung (1).
(EN)
The invention relates to a compressor (30) for a charging device (1) of an internal combustion engine. An iris diaphragm mechanism (50) is arranged upstream of the compressor wheel (13). An actuator (61) is provided which is mechanically coupled to an adjusting ring (53) of the iris diaphragm mechanism (50) so as to transmit a torque of an actuator shaft (62) to the adjusting ring (53) in order to rotate the adjusting ring (53). A pivotal coupling pin (64) is eccentrically arranged on the actuator shaft (62), said coupling pin having a bearing bush (66) which can be moved along a longitudinal axis of the coupling pin (64). The bearing bush (66) is mounted on two fingers (67) of an adjusting lever (53a) of the adjusting ring (53) between the fingers (67) in a movable manner along same. An outer contact surface (71) of the bearing bush (66) has a spherical shape, and inner contact surfaces (72) of the two fingers (67) have a cylindrical shape corresponding to the spherical outer contact surface (71) of the bearing bush (66) and are in sliding contact with the outer contact surface (71) of the bearing bush (66). The invention also relates to a charging device (1).

L'invention concerne un compresseur (30) pour un dispositif de suralimentation (1) d'un moteur à combustion interne. Un mécanisme obturateur à iris (50) est disposé en amont de la roue de compresseur (13). Un actionneur (61) est présent, lequel est couplé mécaniquement avec une bague de positionnement (53) du mécanisme obturateur à iris (50) pour la transmission d'un couple d'un arbre d'actionneur (62) à la bague de positionnement (53) afin de faire tourner la bague de positionnement (53). Une broche de couplage (64) pivotante est disposée de manière excentrique sur l'arbre d'actionneur (62), laquelle possède un coussinet (66) qui peut coulisser le long d'un axe longitudinal de la broche de couplage (64). Le coussinet (66) est supporté entre deux tiges (67) d'un levier de réglage (53a) de la bague de positionnement (53) de manière à pouvoir coulisser le long des tiges (67) sur les tiges (67). Une surface de contact extérieure (71) du coussinet (66) est de configuration sphérique. Les surfaces de contact intérieures (72) des deux tiges (67) sont de configuration cylindrique en correspondance avec la surface de contact extérieure (71) sphérique du coussinet (66) et se trouvent en contact glissant avec la surface de contact extérieure (71) du coussinet (66). L'invention concerne également un dispositif de suralimentation (1).
