Abstract
A turbocharger (1) with variable turbine geometry (VTG). A multiplicity of guide vanes (7) each have a vane shaft (8) mounted in the vane bearing ring (6). An adjusting ring (5) is operatively connected to the guide vanes (7) by way of associated vane levers (20) which are fastened to the vane shafts (8) at one of their ends. Each vane lever (20) has, at the other end, a lever head (23) which can be placed in engagement with an associated engagement recess (24) of the adjusting ring (5). An actuation device (11) has an inner lever (26) which is arranged in the turbine housing (2) and which is connected by means of an adjustment pin (25) to the adjusting ring (5). The adjustment pin (25) has a welding bolt (27) on which a wear-resistant sleeve (28) is arranged.
