- the invention relates to a turbine housing for a
- Exhaust gas turbochargers are increasingly used to increase performance in automotive internal combustion engines. This happens more and more often with the aim of reducing the internal combustion engine with the same or even increased performance in size and weight and at the same time the consumption and thus the
- the operating principle is to use the energy contained in the exhaust gas flow to increase the pressure in the intake tract of the engine and thus to better fill the combustion chamber with air-oxygen and thus implement more fuel, gasoline or diesel, per combustion process, so to increase the performance of the internal combustion engine.
- a conventional exhaust gas turbocharger as shown in FIG. 1, has one in the exhaust gas line of the internal combustion engine
- Turbine wheel 11 and compressor wheel 16 are rotatably attached to the opposite ends of a rotor shaft 17 and thus form the rotor unit of the exhaust gas turbocharger, here referred to as turbo rotor.
- the rotor shaft 17 is rotatably mounted in the bearing housing 100 in a bearing unit arranged between the exhaust gas turbine 101 and the fresh air compressor 102.
- Compressor 16 driven and the exhaust energy so to Used pressure build-up in the intake, where the
- Fresh air mass flow FM (also indicated by arrows) is brought to elevated pressure.
- the hot exhaust gas mass flow AM is directed to the turbine wheel 11.
- the turbine housing 1 and the turbine wheel 11 are so in operation in direct contact with the hot exhaust gas mass flow AM and are thus exposed to very large temperature fluctuations with peak temperatures up to 1000 ° C can be achieved.
- the turbo-rotor rotates at very high rotational speeds of up to 300,000 rpm, whereby in particular the turbine wheel 11 and the turbine housing 1 are exposed to very high mechanical and thermal stresses.
- the turbine housing 1 is connected by means of a bearing housing connecting flange 4 with the centrally disposed bearing housing 100 of the exhaust gas turbocharger. Furthermore, the turbine housing 1 has an exhaust gas inlet duct 2b forming an exhaust gas inlet channel 2 with an exhaust gas inlet flange 2a for connecting the exhaust gas turbocharger to the exhaust manifold (not shown) of an internal combustion engine.
- Exhaust gas inlet channel 2 enters the hot exhaust gas in the
- Turbine housing 1 as is illustrated by means of the exhaust gas mass flow AM shown by arrows. Furthermore, the turbine housing 1 has a spiral channel 5 adjoining the exhaust gas inlet channel 2, which is arranged to taper concentrically around the turbine wheel
- Exhaust inlet gap 5a extends and is open towards this, so that the exhaust gas mass flow AM is guided through the spiral channel 5 in at least a proportionate radial / tangential direction through the exhaust gas inlet gap 5a on the turbine wheel 11.
- the exhaust gas flow AM is deflected in the axial direction in an exhaust gas outlet nozzle 7, through which the
- Abgasaustrittsflansch 3a connects, is derived. in the Transition between the exhaust gas inlet gap 5a and the
- Turbine wheel 11 flows, and thus the turbine wheel 11 drives, the contour gap 12 between the inner contour of the
- Turbine housing and the outer contour of the blading 10 of the turbine wheel 11 are kept as small as possible.
- Contour gap significantly influences the fluidic and thermodynamic properties of the exhaust gas turbine.
- This region of the inner contour of the turbine housing therefore seals the blading 10 of the turbine wheel approximately over the circumference, which is why this region of the inner contour of the turbine housing is referred to below as a sealing contour region 9 or briefly as a sealing contour 9.
- Wastegate device consists of a connecting channel, the wastegate channel 8, between the exhaust gas inlet channel 2 or the spiral channel 5 and the exhaust gas outlet channel 3 and from an associated valve flap 14 with this wastegate channel 8 can be closed or opened as needed.
- the valve flap 14 In order to keep possible losses as low as possible, it must be ensured that the valve flap 14 in case of need with a
- Valve seat 8a on or in the wastegate channel 8 closes as close as possible. Due to the complex internal and external geometries of the turbine housings, traditional turbine housings are designed and manufactured as very solid castings in order to meet the high requirements in terms of form and positional accuracy with simultaneous high thermal and mechanical loads. This embodiment of the turbine housing in addition to the high weight and high heat capacity and high material and manufacturing costs result, which adversely affects the use, operation and cost of such exhaust gas turbocharger.
- thermodynamic efficiency of the turbine due to the manufacturing process, the dimensional accuracy of the sealing contour relative to the turbine wheel may be disadvantageous, since the tolerances of the individual interconnected sheet metal parts may possibly add unfavorably, which in turn is a
