Abstract
A turbocharger (1) with a variable turbine geometry (VTG), includes a guide baffle (18), which has a blade bearing ring (6) with a plurality of guide blades (7), each of the latter having a blade shaft (8) that is mounted on the blade bearing ring (6). The guide baffle also has an adjusting ring (5), which interacts with the guide blades (7) by means of associated blade levers (20), which are fixed to the blade shafts (8) by one of their ends (21). The other end (22) of each blade lever (20) is provided with a lever head (23), which can be engaged in an associated engagement recess (24) of the adjusting ring (5). Each blade lever (20) is asymmetrical and has a bearing lug (25) in the form of an arched segment on only one side of the central section (26).
