Title
(EN) WASTEGATE ACTUATOR MECHANISM OF A WASTEGATE SYSTEM OF A TURBOCHARGER
(FR) MÉCANISME D'ACTIONNEUR DE SOUPAPE DE DÉCHARGE D'UN SYSTÈME DE SOUPAPE DE DÉCHARGE D'UN TURBOCOMPRESSEUR
Abstract
(EN) The invention relates to a wastegate actuator mechanism (300) comprising an elongated link plate (310) and a pin (320) which are rotatable relative to each other. The wastegate actuator mechanism (300) further comprises a sliding assembly (400) including a bushing (410) fixedly connected to the link plate (310) and a sleeve (420) fixedly connected to the pin (320). Assembly of the wastegate actuator mechanism (300) involves pressing the bushing (410) into the eye of the link plate (310) and allowing material of the link plate (310) to deform and to be received in recessed portions (411 ) of the bushing (410) in the process and/or arranging the sleeve (420) on the pin (320) and allowing material of the pin (320) to deform and to be received in recessed portions (421) of the sleeve (420) in a process of forming an end section (322) of enlarged diameter on the pin (320).
(FR) L'invention concerne un mécanisme d'actionneur de soupape de décharge (300) comprenant une plaque de liaison (310) allongée et une broche (320) qui peuvent tourner l'une par rapport à l'autre. Le mécanisme d'actionneur de soupape de décharge (300) comprend en outre un ensemble coulissant (400) comprenant une douille (410) reliée de manière fixe à la plaque de liaison (310) et un manchon (420) relié de manière fixe à la broche (320). L'assemblage du mécanisme d'actionneur de soupape de décharge (300) consiste à presser la douille (410) dans l'œil de la plaque de liaison (310) et à permettre la déformation et la réception d'un matériau de la plaque de liaison (310) dans des parties évidées (411) de la douille (410) dans le processus et/ou à agencer le manchon (420) sur la broche (320) et à permettre la déformation et la réception d'un matériau de la broche (320) dans des parties évidées (421) du manchon dans un processus de formation d'une section d'extrémité (322) de diamètre élargi sur la broche (320).
