Embodiment Construction

[0023] The present invention relates to turbochargers. The turbocharger contains a turbine for expanding the first medium, in particular for expanding the exhaust gas of the internal combustion engine. Furthermore, the turbocharger contains a compressor for compressing the second medium, in particular charge air, ie utilizing the energy extracted in the turbine during the expansion of the first medium. Here, the turbine comprises a turbine housing and a turbine rotor. The compressor includes a compressor housing and a compressor rotor. The compressor rotor is coupled to the turbine rotor via a shaft mounted in a bearing housing positioned between the turbine housing and the compressor housing and connected to both the turbine housing and the compressor housing . The person skilled in the art referred to here is familiar with this basic construction of a turbocharger.

[0024] The invention now relates to such details of the turbocharger as it relates to the connection of t...

Abstract

A turbocharger, has a turbine for expanding a first medium and a compressor in which a second medium is compressed namely by utilizing the energy extracted in the turbine during the expansion of the first medium. The turbine of the turbocharger comprises a turbine housing (1) and a turbine rotor. The compressor of the turbocharger comprises a compressor housing and a compressor rotor coupled to the turbine rotor via a shaft. A bearing housing (2) is arranged between and connected to the compressor housing and the turbine housing (1) in which the shaft is mounted. The turbine and bearing housings (1 ,2) are connected via a fastening device (5) mounted on a flange (6) of the turbine housing (1) with a first section (7) and a second section (9) that covers a flange (10, 15) of the bearing housing (2) at least in sections. The fastening device (5) is contoured curved on a surface of the second section (9) facing the flange (10, 15) of the bearing housing (2).

Description

technical field [0001] The present invention relates to turbochargers. Background technique [0002] The basic design of a turbocharger is known from DE 10 2013 002 605 A1. The turbocharger contains a turbine in which the first medium is expanded. Furthermore, the turbocharger contains a compressor in which the second medium is compressed, ie by utilizing the energy extracted in the turbine during the expansion of the first medium. The turbine of a turbocharger consists of a turbine housing and a turbine rotor. The compressor of a turbocharger consists of a compressor housing and a compressor rotor. The bearing housing is positioned between the turbine housing of the turbine and the compressor housing of the compressor, wherein the bearing housing is connected to the turbine housing on the one hand and to the compressor housing on the other hand. A shaft is mounted in a bearing housing by means of which the turbine rotor is coupled to the compressor rotor. [0003] It i...
