Problems solved by technology

Since the exhaust gas turbochargers used today mostly have uncooled housings, differences between the exhaust gas turbocharger and the base arise when fastening the exhaust gas turbocharger on the base which is relatively cold in most cases. The problem of thermal expansion, which differential thermal expansion can cause stress in the fixture

Embodiment Construction

[0014] figure 1 An exhaust gas turbocharger according to the prior art is shown in side view along the longitudinal axis of the exhaust gas turbocharger. The exhaust gas turbocharger comprises a compressor in a compressor housing 40 and an exhaust gas turbine in a turbine housing 20 . Arranged between them is a bearing housing 50 in which the shaft of the exhaust gas turbocharger is rotatably mounted. The compressor housing comprises an air inlet 41 from which air is conveyed via a compressor wheel and a helical collector to an air outlet 42 . On the air inlet side, a silencer 44 can also be arranged instead of the air intake connection 43 . On the turbine side, the exhaust gas is conducted via the inlet opening 21 onto the turbine wheel and is then conveyed via the outlet opening to the exhaust tract.

[0015] In general, the fastening of the exhaust gas turbocharger takes place by means of two fastening brackets 9 and 10 spaced axially apart from one another. In this cas...

Abstract

The mounting device has a mounting base (10) with a mounting hole (12) and mounting units. A sliding block (17) is arranged between a contact surface of the mounting base and a contact surface of a console (30). The sliding block is connected with the console by the mounting units in a form-fit or force-fit manner. The sliding block forms a sliding surface with the contact surface of the mounting base.

Description

technical field [0001] The invention relates to the field of fluid machines, in particular exhaust gas turbochargers for supercharged internal combustion engines. The invention relates to a fastening device for fastening such an exhaust gas turbocharger to a base, for example a bracket of an internal combustion engine. Background technique [0002] Exhaust turbochargers are used to increase the power of internal combustion engines (piston engines). An exhaust gas turbocharger comprises an exhaust gas turbine in the exhaust gas flow of the internal combustion engine and a compressor in the intake section of the internal combustion engine. The turbine wheel (Turbinenrad) of the exhaust gas turbine is set in rotation by the exhaust gas flow of the internal combustion engine and drives the impeller (Laufrad) of the compressor via a shaft. The compressor increases the pressure in the intake section of the internal combustion engine so that a larger volume of air reaches the com...
