Embodiment Construction

[0036] figure 1 A partial view of a cross-section of a preferred embodiment of the exhaust gas turbocharger according to the invention is shown.

[0037] figure 1 Firstly, two housing parts 3 , 5 are shown, which are designed as bearing housing 3 or compressor housing 5 of the exhaust gas turbocharger. The bearing housing 3 has a preferably annular bearing housing flange 35 with a preferably cylindrical outer surface 36 . Alternatively, the bearing housing flange 35 can also have a rectangular shape or any other geometric shape. The preferably cylindrical outer surface 36 guides on a correspondingly cylindrical inner surface 37 of the compressor housing flange. In an alternative embodiment of the exhaust gas turbocharger according to the invention, the bearing housing 3 is designed with a cylindrical inner surface and the compressor housing 5 is correspondingly designed with a cylindrical outer surface. The bearing housing flange 35 has a sealing ring groove 39 arranged on...

Abstract

The invention relates to an exhaust gas turbocharger (1), in particular for an internal combustion engine (2) of a vehicle, having: a bearing housing (3) for supporting a rotor shaft (4); for accommodating a compressor wheel (6) compressor housing (5); clamping device (10), said clamping device having a first arm section (11) and an engagement section (12), wherein the first arm section (11) placed at least partially on the surface (7) of the support housing (3); and a counter clamping device (20) having a head section (21) and a counter engagement section (22), wherein the head section (21) rests at least partially on the first surface (8) of the compressor housing (5), and wherein the corresponding engagement section (22) is able to form a form fit with the engagement section (12) contact, so that the bearing housing (3) and the compressor housing (5) can be connected to each other in a force-fitting manner. Furthermore, the invention relates to a vehicle and a method for assembling such an exhaust gas turbocharger ( 1 ).

Description

technical field [0001] The invention relates to an exhaust gas turbocharger, a vehicle and a method for equipping such an exhaust gas turbocharger. Background technique [0002] Document DE 10 2004 041 166 A1 describes a known construction of an exhaust gas turbocharger for a vehicle, which essentially consists of a radial turbine and a radial compressor with a compressor wheel arranged in the intake duct of the engine, the compressor wheel The turbocharger shaft is coupled in a rotationally fixed manner to the turbine wheel of the radial turbine. During operation, the exhaust gas flow with high kinetic and thermal energy drives a turbine, which rotates the compressor wheel by being coupled to the turbine shaft. The radial compressor draws in air and compresses it, thereby delivering a correspondingly greater mass of fresh air and thus more oxygen in the intake tract of the engine than in a conventional air-breathing engine. As a result, the mean engine pressure and thus t...
