摘要:
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).

The invention relates to a turbocharger (1) with a variable turbine geometry (VTG), comprising a turbine housing (2) that has a supply channel (9) for exhaust gases, a turbine rotor (4), which is rotatably mounted in the turbine housing (2) and a guide baffle (18), which radially surrounds the exterior of the turbine rotor (4) and 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), said lug being located on the same plane as the lever head (23).

The invention relates to a turbocharger with a variable turbine geometry. Said turbocharger comprises a blade bearing ring assembly (1) with a blade bearing ring (2) and a disc (3), which can be fixed to the blade bearing ring (2) to create a flow channel (4) and also comprises at least one bearing pin (5), one first end (6) of which is connected to the blade bearing ring (2) and the second end (7) of which is connected to the disc (3). Both ends of the bearing pin are butt welded to the blade bearing ring (2) and the disc (3).
