Embodiment Construction

[0024] figure 1 A turbocharger 1 according to the invention is shown having a turbine housing 2 and a compressor housing 3 connected to said turbine housing by a bearing housing 19 . The housings 2 , 3 and 19 are arranged along the axis R of rotation. The turbine housing 2 is partly shown in section in order to show the arrangement of the blade bearing ring 6 as part of a radially outer guide 18 having a pivot axis or blade axis distributed over the circumference and having 8 a plurality of guide vanes 7 . In this way, depending on the position of the guide vanes 7 a larger or smaller nozzle cross-section is formed, and the exhaust gas of the internal combustion engine and / or the fuel cell supplied via the supply line 9 and discharged via the central connecting pipe 10 passes through the nozzle cross-section Impinges more or less centrally on the turbine wheel 4 mounted on the axis of rotation R in order to drive via the turbine wheel 4 a compressor wheel 17 arranged on the ...

Abstract

The invention relates to a turbocharger (1) with variable turbine geometry (VTG), having a turbine housing (2) with a supply duct (9) for exhaust gases; having a turbine wheel (4) which is rotatably mounted in the turbine housing (2); and having a guide apparatus (18), which surrounds the turbine wheel (4) radially at the outside, which has a vane bearing ring (6), which has a multiplicity of guide vanes (7) which each have a vane shaft (8) mounted in the vane bearing ring (6), which has an adjusting ring (5) which 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, wherein 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), and having an actuation device (11) which 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), wherein the adjustment pin (25) has a welding bolt (27) on which a wear-resistant sleeve (28) is arranged.

Description

technical field [0001] The invention relates to a turbocharger according to the preamble of claim 1 . Background technique [0002] A turbocharger of this type is known from EP 1 564 380 A1. [0003] For connecting the inner rod of the actuating device, an adjustment pin is provided, which is connected to the adjustment ring on one side and engages with the inner rod on the other side. A premium base material combined with a wear-optimized surface ensures durability. However, in the case of general purpose turbochargers, this can only be achieved by compromising on weld quality and / or wear resistance. Contents of the invention [0004] It is therefore the object of the present invention to provide a turbocharger of the type stated in the preamble of claim 1 with which a high welding quality and high abrasion resistance. [0005] This object is achieved by the features of claim 1 . The dependent claims relate in each case to other aspects which can be combined with one...
