Charging device i.e. exhaust gas turbocharger for combustion engine, has guide vane lever rotatably connected to guide vane pin and to vane lever pin, and adjusting ring connected to blade lever pin by positive connections

摘要

The turbocharger has a variable turbine/compressor geometry (2) including a vane bearing ring in which a guide vane (8) is rotatably through a guide vane pin (9). A guide vane lever (14) is rotatably connected to the guide vane pin through a first connection (13), and connected to a vane lever pin (16) through a second connection (15). An adjusting ring is connected to the blade lever pin through a third connection (17), where the connections are positively realized by riveting. The vane lever pin and/or the guide vane lever and/or the guide vane pin are made by injection molding.
