Abstract
The invention relates to an exhaust-gas turbocharger (1) having a shaft (2), which has a first centric bore (4) on an end face (3), having a turbine wheel (5), which has a second centric bore (7) in the wheel rear side (6) thereof, having a connection piece (8), which engages into the first and second bores (4, 7); and having an integral connection device (9) for connecting the shaft (2) to the turbine wheel (5), wherein the connection piece (8) is hollow in form.
Description
The present invention relates to a kind of exhaust turbine supercharger according to claim 1 preamble.
Such exhaust turbine supercharger is known from DE10 2009 034420A1.For the turbine wheel of this known exhaust turbine supercharger being connected on a steel axle, provide and in the impeller rear side of this turbine wheel and in the end face of this axle, all make a hole, in this hole, insert the centring pin of a metal, the thermal expansion coefficient of this centring pin corresponds essentially to the thermal expansion coefficient of this ceramic turbine wheel.In addition, provide a kind of brazing to connect this axle and this turbine wheel.
The shortcoming of this arrangement is, this centring pin formed a heat bridge and therefore a large amount of heats from turbine wheel, be introduced into this axle.
Therefore, an object of the present invention is to provide a kind of exhaust turbine supercharger in the specified type of preamble of claim 1, this turbosupercharger makes likely between turbine wheel and this axle, to realize heat and controls.
This purpose is that the feature by claim 1 realizes.
According to the present invention is to provide, this link in these holes in insertion turbine wheel and this axle is in hollow form.Therefore, in this link, formed a kind of air space that heat is controlled part that serves as.This link can be the form in perforated shroud or a closing sleeve in this regard.
Therefore this link has been carried out the task that heat is controlled the centering parts between task and turbine wheel and this axle.
Dependent claims relates to a plurality of favourable development of the present invention.
Particularly, this link can be in a cylindrical parts or a form with the parts of angle section.Under latter event, except this integral type connects, between turbine wheel and this axle, also there is form fit.
In principle, can expect brazing, the connection of tackiness agent bonded type or other welding types to connect and connect as integral type.
Claim 9 and 10 defines of exhaust turbine supercharger according to rotor of the present invention, as a kind of object that can independently introduce to the market.
Further details of the present invention, advantage and feature by by with reference to accompanying drawing from following to becoming clear the explanation of a plurality of exemplary embodiments, in the accompanying drawings:
Fig. 1 shows according to the schematic basis of greatly simplifying of a kind of exhaust turbine supercharger of the present invention and shows, and
Fig. 2 shows through according to the partial cross section obtaining in the attachment point region axle of the rotor of exhaust turbine supercharger of the present invention and turbine wheel, between this turbine wheel and this axle.
Fig. 1 has illustrated the exhaust turbine supercharger 1 with an axle 2 in a schematic presentation of greatly simplifying.The turbine wheel of a turbo machine 4 is arranged at the place, one end of this axle 2.The other end of axle 2 is equipped with the compressor impeller 10 of a compressor 11.One is arranged between compressor 11 and turbo machine 4 for the bearing housing 12 of this axle 2 is installed.Certainly, according to exhaust turbine supercharger of the present invention, also there are the every other parts of this type of pressurized machine, but these do not shown or explained because they are optional for explaining principle of the present invention.
As shown in Fig. 2 is concrete, this axle 2 has first center hole 4 facing on the end face 3 of turbine wheel 5.
Turbine wheel 5 has second center hole 7 in its impeller rear side 6.These holes 4 and 7 are arranged to align with the longitudinal axes L of exhaust turbine supercharger 1.In the embodiment shown, the impeller rear side 6 of turbine wheel 5 is the forms that are in an axially projecting shoulder in the direction of axle 2.Yet, also have likely this impeller rear side 6 to be formed with a smooth surface.
As shown in Figure 2, provide a link 8, after the assembling shown in Fig. 2, under state, this link joins among the first hole 4 and the second hole 7.In order to connect turbine wheel 5 and axle 2, an integral type connection set 9 is also provided, as preamble is set forth, the form that this integral type connection set can be in for example brazing.
Fig. 2 shows, and link 8 is the forms in cannulated sleeve, and this cannulated sleeve has and holds an annular space 13 of controlling the air cushion of part as heat.Therefore this link 8 is not only used as centering parts but also controls part as a heat, and this has reduced the heat of introducing axles 2 from turbine wheel 5.In this regard, certainly likely for length and the diameter that should be used for accordingly adjusting this link 8, to realize the heat of maximum possible, control effect.In addition, can expect equally in principle making hole 4 and 7 extend beyond the length of this link 8, to lengthen this air space 13, make it to exceed this link 8.
Correspondingly, this link 8 can be in being perforated the form of sleeve or a hollow closing sleeve.
It can have cylindrical cross-section or angle section, to also realize a kind of form fit formula except this integral type connects, connects.
This turbine wheel is preferably formed by titanium aluminide (TiAl).Axle 2 is the form in steel axle preferably.
Except to above written disclosure of the present invention, hereby with reference to figure 1 and Fig. 2, with supplementary copy, disclose clearly.
