Definitions

  • the invention relates to a compressor wheel, as it can be used in an exhaust gas turbocharger of a motor vehicle.
  • compressor wheels are manufactured as a one-piece component by a casting process and then completed by a post-processing.
  • Compressor wheel reacts only comparatively slowly to driving forces, d. H. has a comparatively poor response.
  • the object of the invention is to provide a compressor wheel in which the disadvantages mentioned above do not occur.
  • This object is achieved according to the patent claim 1 by a compressor wheel, which has a hub, a Rason and blades, is composed of a plurality of components and in the assembled state has a cavity in the region of the hub.
  • Figure 2 is a sketch of a second component of a
  • Figure 3 is a sketch of the first component and the second
  • a compressor wheel is riding ⁇ be provided having a hub, a wheel rear side and blades, said compressor wheel is composed of several parts and in the assembled state has a cavity in the region of the hub.
  • such a compressor wheel is composed of two components.
  • the first of these two components is the wheel back of the compressor wheel.
  • This Ra07 2 is illustrated in the figure 1. It runs around the central axis 8 of the compressor wheel and contains in the region around the central axis 8 a recess through which the shaft of the exhaust gas turbocharger is guided in the finished assembled compressor wheel.
  • the second component 3 comprises - as can be seen from FIG. 2 - the hub 4 and blades 6, which likewise run around the center axis 8 of the compressor wheel and also have a recess in the area around the center axis 8. In this recess is the hub bore 5, through which the shaft of the Ab ⁇ out gas turbocharger when fully assembled compressor.
  • the hub 4 has a cavity 7.
  • the compressor wheel 1 present after this firm connection of the components 2 and 3 is illustrated in FIG. It has a cylindrical hub bore 5 running around the center axis 8, a hub 4, blades 6 and a wheel back 2.
  • the cavity 7 extending in the hub 4 is covered or closed by the wheel back 2 at the rear side of the Ver ⁇ dense wheel.
  • the compressor wheel illustrated in FIG. 3 can be assembled in a simple manner from the components shown in FIGS. 1 and 2.
  • a cavity 7 is provided in the region of the hub 4, which is covered or closed at the back of the compressor wheel from the first component 2, ie the Rabine.
  • the compressor wheel 1 shown in Figure 3 has a significantly reduced accumulation of material in the region of the hub in comparison to conventional compressor wheels whose hub is formed without a cavity.
  • the weight of the compressor wheel is reduced.
  • the mass moment of inertia of the compressor wheel is reduced.
  • due to the reduced weight and the resulting in the operation of the compressor wheel in the hub bore loads are reduced.
  • the two parts 2 and 3, from which the compressor wheel is together ⁇ assembled properly, can be made in each case by means of a die-casting process, for example.
  • a die-casting process for example.
  • other master or forming processes can also be used to produce these two components, for example MIM processes or additive processes.
  • An advantageous development of the invention is to introduce a bleed ⁇ tion bore 9 at a suitable location of the compressor wheel 1 in order to exclude a possible positive or negative pressure in the cavity 7 can safely.
  • This vent hole 9 connects the cavity 7 with the outside of the compressor wheel.
  • This vent hole 9 is preferably provided in the Ra rectif 2, as illustrated in Figure 3.
  • An alternative embodiment of the invention is to assemble the compressor wheel from more than two components, for example, three or four components. Also in this alternative embodiment, a cavity 7 is provided in the region of the hub 4, which reduces the accumulation of material existing in known compressor wheels in the region of the hub 4.
