    The invention relates to a turbocharger and a carrier for connecting an assembly to a turbocharger.
    The basic structure of a turbocharger is known to the person skilled in the art addressed here. 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 compressor of the turbocharger 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 via which the turbine rotor is coupled to the compressor rotor is mounted in the bearing housing.
    When a turbocharger is in operation, there is a risk that a rotor, such as the turbine rotor or the compressor rotor, of the turbocharger will break and fragments of the rotor will break through the corresponding housing, ie the turbine housing or the compressor housing. There is then the risk that the fragments of the turbocharger will 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 in such a way that damage to the respective housing is not to be expected and fragments of the respective rotor do not penetrate the respective housing even if the respective rotor breaks can. However, this increases the weight of the turbocharger.
    In order not to increase the weight of the turbocharger unnecessarily and also to protect turbochargers already used in the field from breaking through of fragments of a rotor in the environment, it is already known from 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.
    A casing has assemblies such as axial and radial casing segments that are to be mounted on the respective housing of the turbocharger. So far, a simple and reliable assembly of assemblies of a casing on a casing of the turbocharger to be cased has been difficult. The same applies to the attachment of other modules to a housing of a turbocharger. Proceeding from this, the invention is based on the object of creating a novel turbocharger and a carrier for connecting an assembly to a housing of a turbocharger.
    According to a first aspect of the invention, this object is achieved by a turbocharger according to claim 1. The assembly to be mounted on the housing of the turbocharger is mounted directly or indirectly with the aid of a carrier via sections of the assembly or of the carrier on connection areas of the housing, the sections of the assembly or of the carrier in recesses which are formed in the connection areas of the housing, are positively guided. In this way, an assembly can be mounted particularly advantageously on a housing of a turbocharger. The form-fitting guidance of the sections of the assembly or of the carrier at the connection areas of the housing facilitates assembly and reduces the risk of assembly errors. The connection is also secured against rotation and / or displacement, even if a pretensioning force of a screw connection which extends through the sections of the assembly or of the carrier into the connection areas of the housing drops. The assembly can be done easily and reliably.
    According to an advantageous development of the turbocharger, the outer contour of the sections of the assembly or of the carrier and the inner contour of the recesses of the connection areas restrict a relative movement between the housing and assembly or carrier in one degree of freedom or one direction, preferably in two degrees of freedom or two directions . As a result, the twist-proof and / or shift-proof connection can advantageously be provided.
    According to a second aspect of the invention, a carrier for connecting an assembly to a housing of a turbocharger according to claim 8 is carried out. The carrier according to the invention has a basic body. The carrier according to the invention furthermore has first sections which are angled at first edges in a first direction with respect to the base body and via which the carrier can be mounted on the housing of the turbocharger. The carrier according to the invention also has second sections which are angled at second edges in a second direction relative to the base body and via which the assembly to be connected can be mounted on the carrier. The carrier according to the invention allows a simple and reliable assembly of an assembly on a housing of a turbocharger. The carrier has the first sections via which the carrier can be mounted on the housing of the turbocharger. Furthermore, the carrier has the second sections via which the assembly to be connected can be mounted on the carrier and thus via the carrier on the housing of the turbocharger.
    According to an advantageous further development of the carrier, the first sections are angled in the first direction relative to the respective first edge in such a way that they run perpendicular to the base body. The first sections are preferably connected to the base body via intermediate sections, the intermediate sections being angled relative to the base body and the first sections being angled relative to the respective intermediate section. The carrier can thus be easily and reliably mounted on a housing of the turbocharger. The second sections are angled in the second direction relative to the respective second edge in such a way that they run parallel to the base body. The second sections are preferably connected to the base body via intermediate sections, the intermediate sections being angled relative to the base body and the second sections being angled relative to the respective intermediate section. The assembly can thus be easily and reliably mounted on the carrier according to the invention.
    A turbocharger according to the invention according to a third aspect of the invention with at least one carrier according to the invention is defined in claim 13.
    Preferably, all three aspects can be used in combination with one another on a turbocharger, preferably for mounting a casing on a housing of the turbocharger.
    [0012] Preferred developments of the invention emerge from the subclaims and the following description. Embodiments of the invention are explained in more detail with reference to the drawing, without being restricted thereto. It shows:<tb> Fig. 1 <SEP> a perspective section from a housing of a turbocharger together with a carrier according to the invention,<tb> Fig. 2 <SEP> a detail of FIG. 1 in side view and exploded view,<tb> Fig. 3 <SEP> an alternative detail of FIG. 1 in side view and exploded view,<tb> Fig. 4 <SEP> an alternative detail of FIG. 1 in side view and exploded view.
    The basic structure of a turbocharger is familiar to the person skilled in the art addressed here. For example, a turbocharger 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 during expansion of 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 both to the turbine housing and to 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 cased radially on the outside and axially on the outside at least in sections.
    A casing is not only used to provide burst protection. Such a casing can also be used for thermal insulation and sound insulation.
    The present invention relates in particular to a carrier, with the aid of which, in particular, assemblies of such a casing can be easily and reliably mounted on a casing of the turbocharger to be cased. It should be pointed out at this point that other assemblies can also be mounted on a housing of a turbocharger with the carrier according to the invention. However, it is particularly preferred to use them for assembling modules of a casing.
    1 shows a perspective view of a housing 1 of a turbocharger according to the invention together with a carrier 2 according to the invention. FIG. 2 shows a detail from FIG. 1 in a side view with the carrier 2 lifted from the housing 1.
    The carrier 2 has a base body 3 and first sections 4 and second sections 5. The first sections 4 are used to mount the carrier 2 on the housing 1 of the turbocharger. The second sections 5 are used to assemble an assembly on the carrier 2 and thus to assemble this assembly via the carrier 2 on the housing 1 of the turbocharger.
    The first sections 4 of the carrier 2, which are used to mount the carrier 2 on the housing 1 of the turbocharger, are angled at two opposite first edges 6 of the base body 3 of the carrier 2 in a first direction relative to the base body 3. The first edges 6, at which the two first sections 4 are angled in the first direction with respect to the base body 6, run parallel to one another. The second sections 5 of the carrier 2, which serve to connect an assembly to the carrier 2, are angled at two opposite second edges 7 in a second direction with respect to the base body 3, these two second edges 7 also running parallel to one another. The first edges 6 and the second edges 7 run perpendicular to one another.
    The first sections 4 of the carrier 2 and the second sections 5 of the carrier 2 are angled relative to the base body 3 of the carrier 2 in opposite directions. This can be seen from FIGS. 1 and 2, which show that the first sections 4 are angled in the direction of the housing 1, whereas the second sections 4 are angled away from the housing 1.
    The first sections 4 of the carrier 2 are angled in the first direction relative to the respective first edge 6 such that the first sections 4 run perpendicular to the base body 3. 1, 2 it can be seen that the first sections 4, which run perpendicular to the base body 3, engage the base body 3 via intermediate sections 10. These intermediate sections 10 are angled at a first angle with respect to the base body 3, the first sections 4 being angled at a second angle with respect to the intermediate sections 10, these two angles totaling 90 °.
    The second sections 5, first sections 4, which are angled at the second edges 7 relative to the base body 3, are angled in the second direction relative to the respective second edge 7 in such a way that they run parallel to the base body 3. As can best be seen from FIG. 2, these second sections 5 engage the base body 3 via intermediate sections 8, the intermediate sections 8 being angled relative to the base body 3 and the second sections 5 being angled relative to the respective intermediate section 8, namely in such a way that they both angles total 180 °.
    Such a carrier 2 can be particularly advantageously mounted on a housing 1 of a turbocharger via the first sections 4, in particular on connection areas 11 of the housing 1. A casing assembly to be mounted can advantageously be connected to the support 2, namely on the second sections 5 of the carrier 2, which adjoins the housing 1 radially on the outside.
    In order to mount the carrier 2 via its first sections 4 on the housing 1, 4 recesses 9 are made in the first sections. Screws 14 (see FIG. 1) extend through these recesses 9 into the respective connection area 11 of the housing 1, specifically into an internal thread 13 (see FIGS. 2, 3 and 4) which is attached to the respective connection area 11 of the housing 1 is trained.
    As can best be seen from FIGS. 2, 3 and 4, the first sections 4, which are used to mount the carrier 2 on the housing 1, interact with the connection areas 11 of the housing 1.
    It is provided according to the invention that recesses 12 are made in the connection area 11, into which the first sections 4 engage in a form-fitting manner or in which the first sections 4 are guided in a form-fitting manner. These recesses 12 can be formed on the connection areas 11 of the housing 1, for example, by milling or lasering.
    The recesses 12, in which the first sections 4 of the carrier 2 engage positively, guide the carrier 2, namely the first sections 4 of the same, during assembly on the housing 1. The same restrict at least one degree of freedom or in one direction a relative movement between the carrier 2, namely the first sections 4 of the same, and the housing 1, namely the connection areas 12 of the same.
    The first sections 4 of the carrier 2, via which the same is to be mounted on the housing 1 of the turbocharger, accordingly engage positively in corresponding recesses 12 on connection areas 11 of the housing 1, so as to be the carrier 2 to be mounted on the housing 1 in the The positive fit between the first sections 4 and the connection areas 11 of the housing 1 also ensures that undesired displacement of the assembly mounted on the housing 1, in the exemplary embodiment of the carrier 2 shown, is prevented during operation. This can also be ensured when a pretensioning force of the screw connection provided by the screws 14, which extends through the first sections 4 of the carrier 2 into the connection areas 11 of the housing 1, drops.
    An outer contour of the first sections 4 of the carrier 2 corresponds to an inner contour of the recesses 12 of the connection areas 11. The outer contour of the first sections 4 of the carrier 2 can be rectangular or web-like or rod-like (see FIGS. 3, 4). The outer contour of the first sections 4 of the carrier 2 can also be triangular or arrow-shaped (see FIGS. 3, 4). The outer contour of the first sections 4 of the carrier 2 and the inner contour of the recesses 12 of the connection areas 11 restrict a relative movement between the housing 1 and the carrier 2 in at least one degree of freedom or one direction.
    In Fig. 4, in the first section 4 of the carrier 2 visible there, a recess 9 'is formed in addition to the recess 9, which serves for the passage of a screw 14. A material projection 11 'of the connection area 11 delimiting the cutout 12 in sections can snap into the recess 9' in order to form a form fit between the respective first section 4 of the carrier 2 and the respective connection area 11.
    The above details relating to the form fit between the first sections 4 of the carrier and the connection areas 11 of the housing 1 are not limited to the carrier 2 according to the invention. These details can also be used when fastening other assemblies to the connection areas 11 of the housing 1.
