Abstract: A turbocharger for an internal combustion engine, comprises a housing (2) with a compressor blade (3) on the air side, a shaft (1) driving the compressor blade (3), and at least one radially acting rotary bearing (5) for mounting the shaft (3), wherein the rotary bearing (5) is designed as a hydrodynamic sliding bearing, wherein a stationary bearing element (6) is penetrated by the shaft (1) and a first mounting is formed on one first side of the bearing element (6) and acts axially against a bearing collar (7) rotating with the shaft, wherein an oil supply (9) for supplying the mountings is designed in the bearing element (6), wherein a plurality of flow surfaces (10) with a height (h) varying in the circumferential direction is formed on one surface of the bearing element (6) facing the bearing collar (7) in the axial direction, wherein an individually dimensioned throttle element (11, 12) is designed in the oil supply (9) for each of the two mountings.

Abstract: The disclosure relates to a turbocharger for an internal combustion engine, comprising a housing (2) with a compressor blade (3) on the air side, a shaft (1) driving the blade (3), and at least one radially acting rotary bearing (5) for mounting the shaft (1). The bearing (5) is designed as a hydrodynamic sliding bearing, and a stationary bearing element (6) is penetrated by the shaft (1) and a first mounting is formed on one first side of the bearing element (6) and acts axially against a bearing collar (7) rotating with the shaft (1). The bearing element (6) forms a second mounting on an opposite second side which acts axially against a sealing bushing (8) rotating with the shaft (1). An oil supply (9) is designed in the bearing element (6), a plurality of flow surfaces (10) is formed on one surface of the bearing element (6) facing the collar (7) in the axial direction, and an individually dimensioned throttle element (11, 12) is designed in the oil supply (9) for each of the two mountings.
