Definitions
- the invention relates to an exhaust-gas turbocharger according to the preamble of claim 1.
- the bearing housing and the turbine housing of an exhaust-gas turbocharger of said type have a relatively large contact surface owing to the provision of a force- transmitting axial surface and a radial centering surface.
- the bearing arrangement of the exhaust-gas turbocharger in the bearing housing is subject to high thermal loading.
- the notches may be provided in a turbine-housing-side abutment surface and/or in a bearing-side abutment surface.
- a contact surface of a radial centering surface pairing can be reduced, for example through the formation of notches or the division of the centering surface pairing into a multiplicity of centering points of small area.
- At least one thermal insulator is arranged between the axial abutment surfaces, which thermal insulator performs the transmission of force and the thermal insulation and thus prevents any direct contact between the axial abutment surfaces.
- thermal insulator it is possible here for the thermal insulator to be in the form of a closed ring or else in the form of a multiplicity of segments with clearly defined breaking edges.
- thermal insulator prefferably arranged in a groove in the bearing housing and/or in the turbine housing such that an ingress of fragments into the exhaust-gas turbocharger in the event of the thermal insulator becoming damaged can be prevented.
- the one or more thermal insulators can be of such a size as to extend behind the turbine wheel. It is alternatively possible for an additional thermal insulator to be arranged in the region behind the turbine wheel.
- FIG. 1 shows a schematically slightly simplified sectional illustration through an exhaust-gas turbocharger according to the invention
- Figure 2 shows an illustration, corresponding to Figure 1, of a sub -region of the bearing housing and of the turbine housing according to a second embodiment of the exhaust-gas turbocharger according to the invention
- Figure 3 shows a slightly simplified perspective detail illustration of a centering lobe arrangement.
- the exhaust-gas turbocharger 1 illustrated in Figure 1 has a compressor housing 2 with a compressor wheel 2' arranged therein, a bearing housing 3, and a turbine housing 4, said housings being mounted on one another.
- the bearing housing 3 serves for mounting a shaft 12 which, on one end, bears the compressor wheel 2' and, on its other end, bears a turbine wheel 4' which is arranged in the turbine housing 4.
- the turbine housing 4 has a turbine -housing-side axial abutment surface 5.
- the bearing housing 3 has a bearing-housing-side axial abutment surface 6.
- centering surface pairing formed by a turbine -housing- side centering surface 7 and a bearing-housing-side centering surface 8.
- the axial abutment surfaces 5, 6 have a notch 9 in which, in the particularly preferred embodiment illustrated in Figure 1, there is arranged a thermal insulator 10 which may be constructed for example from ceramic material.
- a thermal insulator 10 which may be constructed for example from ceramic material.
- the embodiment illustrated in Figure 1 is however preferable owing to the provision of a thermal insulator 10, because, by means of said thermal insulator 10, contact between the abutment surfaces 5 and 6 can be prevented, as emerges from the illustration of Figure 1. In this case, the transmission of force between the bearing housing 3 and the turbine housing 4 takes place via the thermal insulator 10, as illustrated in Figure 2.
- Figure 2 shows that it is possible for the thermal insulator 10 to be of such a size that, as viewed in the radial direction R of the exhaust-gas turbocharger 1 , it extends behind the turbine wheel 4', which permits a further reduction of the transfer of heat into the bearing housing 3.
- the radial centering surface pairing 7, 8 may be in the form of a centering lobe arrangement, wherein in Figure 1, owing to the selected illustration, one centering lobe 11 is visible.
