Definitions

  • the invention relates to a Verstellwellenan accent a VTG turbocharger or waste gate door bolster according to the preamble of claim 1.
  • VTG turbocharger is a variable turbine geometry (VTG) turbocharger that requires a variable shaft arrangement.
  • VTG turbocharger is a variable turbine geometry (VTG) turbocharger that requires a variable shaft arrangement.
  • Waste-Gate turbocharger the turbine bypass is controlled by means of a flap which is moved by the adjusting shaft.
  • a static seal is provided between the adjusting shaft and the bush, which at least substantially reduces, if not completely suppresses, exhaust gas and soot emissions of the turbocharger via the bushing to the outside.
  • the seal is designed as a piston ring.
  • the seal is arranged in a groove of a main body of the adjusting shaft between a fixing portion and a free end.
  • the main body is stepped, so that there are two cylindrical sections with different outer diameter.
  • the inner contour of the bush surrounding the main body is also designed to be complementary in a stepped manner, so that in turn results in two areas with a cylindrical inner diameter of different dimensions.
  • the transition of both areas can be formed as a slip chamfer for the piston ring assembly, so that the longest possible effective sealing gap both ends remain.
  • the conditional by the transition annular space between the bush and adjusting can serve as a collection volume for particles. Due to the accumulation of particles in the collecting volume, accumulation in the sealing gap is avoided, which can lead to the stiffness of the adjusting shaft.
  • the outer diameter of the bushing does not necessarily have to be stepped. It can also be constant over the entire socket length. A gradation of the bush outer diameter has the added advantage of preventing reverse misplacement.
  • Fig. 1 a known Verstellwellenan extract 1 of a VTG turbocharger is shown.
  • the VTG turbocharger itself is not shown in detail in the figures, since this may be a conventional construction known per se.
  • the adjusting shaft arrangement 1 has an adjusting shaft 2, which comprises a fixing section 3 and a free end 8.
  • Fig. 1 further shows that the fixing portion 3 and the free end 8 have a smaller outer diameter than a Main body 6 of the adjusting shaft 2, which is arranged between the fixing section 3 and the free end 8. All three sections have in the example case a cylindrical outer contour.
  • the adjusting shaft 2 is connected via the fixing section 3 with a lever 4.
  • the adjusting shaft arrangement 1 has a socket 5 which is arranged on the base body 6 of the adjusting shaft 2.
  • a seal 7 is provided, which is arranged in the region of the base body 6 between the sleeve 5 and the adjusting shaft 2.
  • the base body 6 has a circumferential groove and the seal may preferably be formed as a piston ring, which is arranged in the groove 9.
  • the base body 6 of the adjusting shaft 2 is formed continuously cylindrical or smooth and on both sides of the bushing slip chewing are clearly visible.
  • FIG. 2 illustrated first embodiment of Verstellwellenan angel invention provided with a base body 6, which is stepped, so that there are two cylindrical sections 10 and 11, which have different outer diameter.
  • the portion 10 has a larger outer diameter than the portion 11th
  • the bush 5 in the region of the section 10 has a larger inner diameter than in the region which surrounds the section 11 of the adjusting shaft 2.
  • the seal 7 is arranged in a groove of the base body 6.
  • the socket 5 also has two portions 12 and 13, wherein the portion 12 of larger inner diameter surrounds the portion 10 of the adjusting shaft 2, while the portion 13 surrounds the region 11 of the adjusting shaft 2 with a smaller outer diameter.
  • the portion 12 of the sleeve 13 also has a smaller outer diameter than the portion 13 of the sleeve 5.
  • Fig. 3 a second embodiment is shown, which is provided for a waste gate turbocharger. Since the formation of an adjustment also those of Fig. 2 may be referred to the above statements.
