    专利说明:

    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 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 casing for turbochargers have axial shuttering segments, which connect axially on the outside of the housing to be shuttered to the housing to be shuttered. Furthermore, casings known from practice have at least one radial casing segment which adjoins the housing to be casing radially on the outside and extends between opposite axial casing segments.
    Known from practice formwork with axial formwork segments and at least one radial formwork segment have a substantially U-shaped shape in cross section. Such a U-shape is preferred in terms of low manufacturing costs and low component complexity, but the vibration excitation of such formwork is disadvantageous. There is therefore a need for a casing for a turbocharger which, with its low weight and low component complexity, is less prone to vibrate during operation of the turbocharger.
    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.
    At least one stiffening element is formed on at least one formwork segment or at least one stiffening element acts on at least one formwork segment. With low component complexity and low manufacturing costs, the structural rigidity of the formwork can be improved. The risk is reduced that the casing tends to vibrate during operation of the turbocharger.
    A plurality of rib-like or embossed stiffening elements are preferably formed on at least one axial formwork segment or several stiffening elements act on at least one axial formwork segment. Rib-like or embossed stiffening elements on at least one axial formwork segment are particularly preferred for increasing the structural rigidity of the formwork and for reducing the tendency of the formwork to vibrate.
    [0011] Preferably, first stiffening elements are formed on an outside and / or second stiffening elements on an inside of the respective axial formwork segment. A configuration of the stiffening elements is particularly preferred if they extend both in the radial direction and in the axial direction and thus form clip-like ribs which extend in the radial direction along two opposite axial formwork segments and along an axial formwork segment positioned between them. The structural rigidity can hereby be increased particularly advantageously and the tendency of the casing to vibrate can be reduced.
    The turboader according to the invention is defined in claim 9.
    Preferred further 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:

    CH 714 651 A2
    2 shows a perspective view from the inside of a detail of a further embodiment of the casing according to the invention,
    Fig. 3 is a perspective view from the outside of a detail of a further embodiment of the formwork according to the invention.
    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.
    [0016] 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.
    [0019] A casing serves not only to provide burst protection. Such formwork can also be used for thermal insulation and sound insulation.
    Fig. 1 shows a perspective view of a casing 1 for a housing of a turbocharger, for example for a turbine housing or compressor housing of a turbocharger, not shown.
    The formwork 1 has opposing axial formwork segments 2 and 3, with an axial formwork segment 2, 3 being arranged on each axial side of a housing to be formwork adjacent to the housing.
    The casing 1 also has at least one radial casing segment 4, 5, which extends between opposite axial casing segments 2, 3 and adjoins the respective casing to be clad radially on the outside.
    Designs in which there are two radial shuttering segments which overlap in the radial direction are particularly preferred. In this case, starting from the axial formwork segment 2, a first radial formwork segment 4 extends in the direction of the second axial formwork segment 3 and, starting from the second axial formwork segment 3, a second radial formwork segment 5 in the direction of the first axial formwork segment 2. The overlapping radial formwork segments 4, 5 can then be connected to one another.
    In order to reduce the susceptibility to vibration of the formwork, it is proposed that at least one stiffening element be formed or act on at least one formwork segment.
    In the embodiment shown in FIG. 1, a plurality of stiffening elements are formed on the axial formwork segment 3, namely on an outer side 3a thereof and on an inner side 3b thereof, namely on the outer side 3a first stiffening elements 6 and on the inner side 3b second Stiffening elements 7. Such stiffening elements can also be formed on the outside 2a and the inside 2b of the opposite axial formwork segment 2.
    The formed on the outside 3a of the axial shuttering segment 3 first stiffening elements 6 have a T-shaped contour with first sections 6a, which extend in the radial direction, and with second sections 6b, which extend in the circumferential direction. These stiffening elements 6 accordingly form T-shaped ribs. The second stiffening elements 7 are formed on the inside 3b of the axial formwork segment 3 and are preferably contoured in a wedge shape. These wedge-shaped stiffening elements 7 engage on the inside 3b of the axial formwork segment 3 and on an inside 4b, 5b of an adjacent radial formwork segment 4, 5.
    The first stiffening elements 6, which are formed on the outside 3a of the axial shuttering segment 3, point away from the housing to be shuttered. The second stiffening elements 7, which are formed on the inside 3b of the axial shuttering segment 3, point towards the housing to be shuttered.
    CH 714 651 A2 [0028] FIG. 2 shows a view from the inside of an axial formwork segment 2 and an adjacent radial formwork segment 4 of a formwork, wherein, in FIG. 2, wedge-shaped second stiffening elements 7 formed on the inside 2b of the axial formwork segment 2 are visible , These wedge-shaped second stiffening elements 7 extend essentially in the radial direction and the axial direction. These wedge-shaped second stiffening elements 7 act on the one hand on the inside 2b of the axial formwork segment 2 and on the other hand on the inside 4b of the radial formwork segment 4.
    3 shows a view from the outside of an outer side 2a of an axial formwork segment 2 and an outer side 4a of an adjacent radial formwork segment 4. Here, in turn, a plurality of first stiffening elements 6 are formed on the outer side 2a of the axial formwork segment 2, which extend in the radial direction extend and which connect with their radially inner ends to a circumferential, closed stiffening element 8.
    In the exemplary embodiments shown, all stiffening elements 6, 7 and 8 are formed by rib-like structures. It is also possible to design corresponding stiffening elements by embossing.
    Stiffening elements designed as embossments are integrally formed on the respective formwork segment by reshaping.
    Stiffening elements 6, 7 and 8 designed as ribs can be integrally formed on the respective formwork segment or can be designed as a separate assembly and connected to the same by preferably welding or riveting or screwing.
    In a variant of the invention, not shown, it is provided that stiffening elements formed on an outside of the formwork 1 extend like clips around the formwork segments, namely around two opposite axial formwork segments 2, 3 and over a radial formwork segment extending between them 4, 5. In this case, the clamp-like stiffening elements then extend in the area of the axial formwork segments 2 and 3 on an outer side 2a and 3a thereof in the radial direction and in the area of or a radially outer position of the radial formwork segment 4 or 5 on an outer side 4a or 5a the same in the axial direction. With such clamp-like stiffening elements in the area of the outside of the casing 1 and thus the outside of the casing segments 2, 3, 4, 5, the structural rigidity of the casing 1 can be increased particularly advantageously.
    Such bracket-like stiffening elements could also be formed on the inside of the axial formwork segments 2 and 3 and a radial formwork segment 4 or 5. In this case, the clamp-like stiffening elements then extend in the area of the axial formwork segments 2 and 3 on an inner side 2b and 3b thereof in the radial direction and in the area of or a radially inner position of the radial formwork segment 4 or 5 on an inner side 4b or 5b thereof in the axial direction.
    [0035] The stiffening elements can be distributed regularly over the respective formwork segment or can only be provided in selected areas of the same.
    The invention further relates to a turbocharger with 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.
