Embodiment Construction

[0025] The exhaust gas turbocharger, which is not shown in detail, has a first housing section in the form of a flow-through exhaust gas guide section which, during operation of the exhaust gas turbocharger, is supplied by a fluid , usually flowed through by the exhaust gas. The exhaust gases are generally, but not necessarily, combustion products of an internal combustion engine, not shown in detail.

[0026] The exhaust-gas turbocharger is associated with a second housing section, which is designed as a bearing section and serves to support a not-shown impeller of the exhaust-gas turbocharger. The bearing section is positioned between a not shown in detail flow-through air guide section and the exhaust gas guide section of the exhaust gas turbocharger.

[0027] The impeller (not shown in detail) has a compressor rotor (not shown in detail) and a turbine rotor (not shown in detail), which are connected to one another in a rotationally fixed manner by means of a shaft (not sh...

Abstract

The invention relates to a connection device for a turbocharger, comprising a substantially bent first element (2) and a substantially bent second element (3). The first element (2) and the second element (3) are connected together in a releasable manner in a first end region (6) or a second end region (7) and in a movable manner in a third end region (17) or a fourth end region (21). A first receiving section (16) extends between the first end region (6) and the third end region (17), and a second receiving section (19) extends between the second end region (7) and the fourth end region (21).According to the invention, the connection device (1) has a receiving area (27) formed in the element (2; 3) in order to reduce stress. The invention further relates to a turbocharger comprising a connection device (1).

Description

technical field [0001] The invention relates to a connection device for an exhaust gas turbocharger of the type specified in the preamble of claim 1 . Furthermore, the invention relates to an exhaust gas turbocharger according to the preamble of claim 8 . Background technique [0002] Expediently, the exhaust gas turbocharger is formed from a plurality of housing sections: a first housing section, through which hot gas, usually the exhaust gas of an internal combustion engine, flows through; a second housing section, which is designed to accommodate the The impeller is rotatably mounted in the second housing section and is positioned between the first housing section and a third housing section through which ambient air can usually flow. Between the individual housing sections, the flange surfaces are formed in such a way that they can touch each other, so that the escape of hot air and ambient air is avoided as far as possible. As long as a leak is caused between the flan...
