Abstract
The invention relates to a wastegate actuator mechanism comprising an elongated link plate and a pin which are rotatable relative to each other. The wastegate actuator mechanism further comprises a sliding assembly including a bushing fixedly connected to the link plate and a sleeve fixedly connected to the pin. Assembly of the wastegate actuator mechanism involves pressing the bushing into the eye of the link plate and allowing material of the link plate to deform and to be received in recessed portions of the bushing in the process and/or arranging the sleeve on the pin and allowing material of the pin to deform and to be received in recessed portions of the sleeve in a process of forming an end section of enlarged diameter on the pin.
Claims12
A wastegate actuator mechanism configured to be used in a wastegate system of a turbocharger,
- wherein the wastegate actuator mechanism comprises a elongated link plate, which has an elongated shape, and a pin that is attached to a lever plate, wherein the pin extends partially through an eye provided in the link plate, and wherein the link plate and the pin are rotatable relative to each other about a rotation axis extending in the longitudinal direction of the pin, wherein the wastegate actuator mechanism further comprises a sliding assembly arranged between the link plate and the pin at the position of the eye of the link plate, wherein the sliding assembly comprises a bushing that is fixedly connected to the link plate and a sleeve that is fixedly connected to the pin, and wherein an inner surface of the bushing and an outer surface of the sleeve are in sliding contact,
- wherein at an interface of the bushing and the link plate, the bushing is provided with recessed portions and bulges of material of the link plate are received in the recessed portions, and
- wherein the recessed portions of the bushing are notches that are distributed at a regular distance in a peripheral direction on chamfered outer rims of the bushing which are present at each of two axial ends of the bushing.
