    Description: [0001] The invention relates to an exhaust-gas turbocharger.
    An exhaust gas turbocharger has a turbine and a compressor. The turbine of the exhaust gas turbocharger serves for the expansion of exhaust gas, which leaves an engine, and for the recovery of energy during the expansion of the exhaust gas. The compressor of an exhaust gas turbocharger serves to compress the charge air to be supplied to the engine by means of the energy obtained in the turbine. The turbine has a multi-part turbine housing and a turbine rotor positioned in the turbine housing. The compressor has a multi-part compressor housing and a compressor rotor positioned in the compressor housing. Compressor rotor and turbine rotor are coupled via a shaft.
    In the operation of an exhaust gas turbocharger there is a risk that, for example, the compressor rotor breaks and fragments of the compressor rotor penetrate the compressor housing and fly into the environment of the exhaust gas turbocharger. A similar damage event can also occur in the area of the turbine of the exhaust gas turbocharger. In order to take this problem into account, the compressor housing and possibly the turbine housing is designed in such a way that damage of the respective housing is not to be expected and even when breaking the respective rotor fragments of the same housing can not penetrate in known from practice exhaust gas turbochargers. As a result, however, on the one hand, the weight of the exhaust gas turbocharger is increased, on the other hand, these measures can only be used in newly designed exhaust gas turbochargers. Already existing, older exhaust gas turbochargers, however, can not be redesigned, so they have no corresponding protection and therefore can get into the environment in case of damage fragments of rotor and housing.
    On this basis, the present invention has the object to provide a novel exhaust gas turbocharger. This object is achieved by an exhaust gas turbocharger according to claim 1. According to the invention, housing parts of the multi-part compressor housing and / or housing parts of the multi-part turbine housing are clamped with the aid of at least one clamping holder. The invention provides an effective burst protection or containment protection for a compressor and / or a turbine of an exhaust gas turbocharger. With the clamp holders already existing, installed or used in the field exhaust gas turbocharger can be easily retrofitted or retrofitted according to the invention.
    Preferably, each clamp holder is substantially C-shaped with two opposing jaws and at least one extending between the jaws clamping strut, each clamp is bolted to the body parts to be clamped in the region of its jaws and axially braced. Such clamp holders are simple and provide effective burst protection or containment protection, with which even existing exhaust gas turbochargers can be easily retrofitted.
    According to an advantageous embodiment, the multi-part compressor housing is axially braced over a plurality of clamping holder, wherein each of the clamping holder engages on the one hand on a volute casing and on the other hand on a bearing housing of the compressor housing. In this case, in the region of the compressor housing, each of the clamping holders is screwed via its clamping jaws to the spiral housing and to the bearing housing, preferably such that at least one continuous tie rod extends through the spiral housing and through at least one of the clamping jaws of the respective clamping holder, which faces the housings the compressor housing and opposite to the respective jaw of the respective clamping holder protrudes and attack on which clamping nuts. These features serve to provide a simple burst protection or containment protection in the region of the compressor of the exhaust gas turbocharger.
    According to a further advantageous embodiment, the multi-part turbine housing of the exhaust gas turbocharger is clamped over a plurality of clamping brackets, each of the clamps on the one hand acts on a Zuströmgehäuse and on the other hand to a discharge housing of the turbine housing, namely in an analogous manner as in the region of the compressor housing on the volute casing and on the bearing housing of the compressor housing. These features serve to provide a simple containment protection or burst protection in the turbine of the exhaust gas turbocharger.
    Preferably, each clamp holder is additionally fixed to the compressor housing or turbine housing via a radially or partially overlapping radially outwardly overlapping radial securing means. As a result, the containment protection or bursting protection can be further improved.
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawing. Showing:
