    Description: The invention relates to a casing of a turbocharger and a turbocharger.
    The basic structure of a turbocharger is known to those skilled in the art. A turbocharger has a turbine in which a first medium is expanded. Furthermore, a turbocharger has a compressor in which a second medium is compressed, using the energy obtained in the turbine when the first medium is expanded. The turbine of the turbocharger has a turbine housing and a turbine rotor. The turbocharger's compressor has a compressor housing and a compressor rotor. A bearing housing is positioned between the turbine housing of the turbine and the compressor housing of the compressor, the bearing housing being connected on the one hand to the turbine housing and on the other hand to the compressor housing. A shaft is mounted in the bearing housing, via which the turbine rotor is coupled to the compressor rotor.
    In the operation of a turbocharger, there is a risk that a rotor, for example the turbine rotor or the compressor rotor, of the turbocharger breaks and fragments of the rotor break through the corresponding housing, that is to say the turbine housing or the compressor housing. There is then a risk that the fragments of the turbocharger, in particular of the rotor, get into the environment. In order to take account of this problem of the bursting of a rotor of the turbocharger, the respective housing in turbochargers known from practice is designed such that a damage to the respective housing is not to be expected and even if the respective rotor breaks, fragments thereof do not penetrate the respective housing can. However, this increases the weight of the turbocharger. In order not to unnecessarily increase the weight of the turbocharger and also to protect turbochargers already used in the field from breakdown of fragments of a rotor into the environment, it is already known in practice to equip a turbocharger with a casing which surrounds a turbine housing and / or a compressor housing and / or a bearing housing of the turbocharger radially on the outside and axially on the outside at least in sections.
    Known from practice shuttering for turbochargers have axial shuttering elements, which connect axially on the outside of the housing to be shuttered to the housing to be shuttered. Furthermore, casings known from practice have radial casing elements which adjoin the housing to be casing radially on the outside. The radial formwork elements have opposite ends, which define a recess for the passage of an entry flange or exit flange of the housing to be formworked. At this position, previously known casing has a weak point, so that in the event of damage, fragments of the rotor can reach the outside in the event of damage. This is a disadvantage.
    Proceeding from this, the invention has for its object to provide a novel formwork of a turbocharger and a turbocharger with such a formwork.
    This object is achieved by a casing of a turbocharger according to claim 1. The formwork according to the invention has an additional formwork segment which at least in sections encloses and / or supplements the axial formwork segments and / or the radial formwork segments in the region of an inlet flange or outlet flange of the housing to be formworked.
    The vulnerability in previously known cladding is closed via the additional cladding segment. The additional formwork element encloses and / or supplements, at least in sections, the axial formwork elements and / or the radial formwork elements in the region of the passage opening for the inlet flange or outlet flange. In particular, containment protection or burst protection that can be provided by the casing can be increased.
    Preferably, the radial shuttering segments have opposite ends that define a recess for the inlet flange or outlet flange of the housing to be shuttered, these opposite ends of the radial shuttering segments being connected by the additional shuttering segment. As a result, the containment protection or burst protection that can be provided by the casing can be increased particularly advantageously.
    Preferably, the additional shuttering segment has a surrounding section which, at a first end of the radial shuttering segments adjacent to the inlet flange or outlet flange, partially encloses and supplements the axial shuttering segments and / or the radial shuttering segments. The additional formwork segment is connected to the radial formwork segments and / or axial formwork segments via the encircling section in the region of the first end of the radial formwork segments. Starting from the encircling section of the additional casing segment, fastening sections of the additional casing segment extend in the direction of the second end of the radial casing segments. The additional shuttering segment is connected to the axial shuttering segments and / or in the region of the second end of the radial shuttering segments to the radial shuttering segments via the fastening sections. These features also serve to increase the containment protection or burst protection provided by the casing in a particularly advantageous manner.
    [0011] The turbocharger according to the invention is defined in claim 10.
    CH 714 847 A2 [0012] Preferred developments of the invention result from the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted to this. It shows:
    1 is a perspective view of a casing according to the invention for a turbocharger,
    FIG. 2 shows the casing of FIG. 1 with a casing of the turbocharger to be casing;
    Fig. 3 shows the arrangement of Figure 1 without additional formwork segment.
    4 shows a detail from the casing of FIG. 1 in a side view;
    5 shows a partial cross section through the casing of FIG. 1.
    The invention relates to a casing of a turbocharger and a turbocharger with a casing.
    The basic structure of a turbocharger is familiar to the expert addressed here. A turbocharger thus comprises a turbine for expanding a first medium, in particular for expanding exhaust gas, and a compressor for compressing a second medium, in particular for compressing charge air, using the energy obtained in the turbine when expanding the first medium. The turbine has a turbine rotor and a turbine housing. The compressor has a compressor rotor and a compressor housing. The turbine rotor and the compressor rotor are coupled via a shaft which is mounted in a bearing housing of the turbocharger, the bearing housing being connected to both the turbine housing and the compressor housing.
    If, for example, the turbine rotor or the compressor rotor breaks during operation, fragments of the same can break through the respective housing, that is to say the turbine housing or the compressor housing, and get into the environment. This must be avoided, for which it is known to equip a turbocharger with a casing which surrounds the turbine housing and / or the compressor housing and / or the bearing housing of the turbocharger.
    Preferably, in the area of the turbine housing and the compressor housing, a separate casing is used, which surrounds the respective casing of the turbocharger to be clad radially on the outside and axially on the outside at least in sections.
    1 to 5 show a formwork 1 according to the invention, the formwork 1 according to the invention being shown in FIGS. 2 and 3 together with a turbine housing 6 of a turbine of the turbocharger to be formulated. The casing 1 is arranged around a turbine inflow housing 6a of the turbine housing 6 at least in sections. The casing therefore surrounds the turbine inflow casing 6a of the turbine casing 6 to be casing, at least in sections. 2 and 3 also show a turbine outflow housing 6b of the turbine housing 6. Furthermore, FIGS. 2 and 3 show an inlet flange 6c of the turbine inflow housing 6a. The turbine inflow housing 6a can be connected to an exhaust gas line via this inlet flange 6c in order to supply hot exhaust gas to the turbine inflow housing 6a which is to be expanded in the turbine.
    The formwork 1 has axial formwork segments 2, 3, which are arranged axially outside laterally next to the casing 6a to be clad and connect axially outside to the casing 6a to be clad and cover the same axially at least in sections.
    Furthermore, the casing 1 has radial casing segments 4, 5 which adjoin the housing 6a to be clad radially on the outside and surround the same radially on the outside at least in sections. The radial formwork segments 4, 5 essentially extend between the axial formwork segments 2 and 3.
    In particular, it is provided that a first radial formwork segment 4 is connected to a first axial formwork segment 2 and extends from this first axial formwork segment 2 in the direction of a second axial formwork segment 3. A second radial formwork segment 3 is connected to the second axial formwork segment 3 and extends from the second axial formwork segment 3 in the direction of the first axial formwork segment 2.
    The radial shuttering segments 4 and 5 form, as can best be seen in FIG. 3, opposite ends 7, 8. Between these opposite ends 7, 8 of the radial shuttering segments 4, 5, a recess 9 is formed for the passage of the inlet flange 6c of the housing 6a to be shuttered. In the area of this inlet flange 6c, the housing 6a to be clad is not covered or surrounded by the radial cladding segments 4, 5 and the axial cladding segments 2, 3, so that the cladding 1 would have a weak point here.
    In order to close this weak point, it is provided according to the invention that the casing 1 has an additional casing segment 10. The additional formwork segment 10 encloses and / or supplements, at least in sections, the axial formwork segments 2, 3 and / or the radial formwork segments 4, 5 in the region of the entrance
    CH 714 847 A2 flange 6c or adjacent to the inlet flange 6c of the housing 6 to be clad and thus increases the burst protection or containment protection that can be provided by the cladding.
    The additional shuttering segment 10 connects the ends 7, 8 of the radial shuttering segments 4, 5, which define the passage opening 9 for the inlet flange 6c of the housing 6a to be shuttered, with one another, and thus increases the containment protection or burst protection in a particularly advantageous manner ,
    The additional formwork segment 10 has a surrounding section 10a. The encircling section 10a supplements and encloses the axial cladding segments 2, 3 and the radial cladding segments 4, 5 at a first end 7 of the radial formwork segments 4, 5 adjacent to the inlet flange or outlet flange. This encircling section 10a is connected to the first end via first fastening means 11 7 of the radial formwork segments 4, 5 and the second fastening means 12 are connected to an adjacent area of the axial formwork segments 2, 3. According to FIG. 2, the surrounding section 10a of the additional shuttering segment 10 encloses the shuttering segments 2, 3, 4 and 5 on three sides adjacent to the inlet flange 6c of the housing 6a to be shuttered.
    Starting from the surrounding section 10a of the additional shuttering segment 10, fastening sections 10b extend laterally in the direction of the second end 8 of the radial shuttering segments 4, 5. The additional shuttering segment 10 is in the region of the second end 8 of the radial shuttering segments 4, 5 with second fastening means 13 the radial formwork segments 4, 5 and / or the axial formwork segments 2, 3 are connected in a region adjacent thereto.
    With the present invention, the containment protection or burst protection that can be provided by a formwork can be significantly increased. In particular, where the casing has a recess for the passage of an inlet flange or outlet flange of a housing to be casing, the burst protection or containment protection can be significantly increased.
    The additional formwork segment 10 of the formwork 1 used to increase the burst protection or containment protection can be made in one piece or in several parts.
    The additional cladding segment 10 encloses and / or supplements the cladding 1 in the region of a recess for the passage of the inlet flange or outlet flange of the housing to be clad. Ends which limit the recess for the passage of the inlet flange or outlet flange are particularly preferably connected to one another by the additional formwork segment, as a result of which the containment protection can be further increased. The additional formwork segment 10 reinforces the formwork 1 in the region of a recess 9 for the passage of the inlet flange or outlet flange of the housing to be formwork like a ruff.
    The invention further relates to a turbocharger with such a casing, which is preferably arranged around a turbine inflow housing of a turbine housing of a turbine of the turbocharger. However, the casing can also be used in the area of a compressor housing of the turbocharger.
