Definitions

  • the present invention relates to a twin-flow turbine housing according to the preamble of claim 1.
  • turbines such as the turbine part of a turbocharger for Motor vehicles to use turbine housing of various kinds.
  • turbine housings made of cast iron have a helical inlet space for the combustion gases from the engine be supplied via a manifold to the turbine part of a turbocharger, from where they then For example, by an annular gap, which has a mechanism for varying the Flow geometry may be supplied to the turbine wheel.
  • the helical inlet space surrounds the actual turbine chamber and forms with this together the turbine housing in which the turbine wheel and the mechanism are housed for geometry variation.
  • the turbine housing made of sheet metal, advantageously in double-walled construction, on the one hand to save weight, but above all, what It is more important to over-cool the exhaust gases of the engine when the turbocharger is cold Prevent, as the downstream catalyst through the exhaust gases as soon as possible Operating temperature must be heated to achieve its full effect.
  • the present invention is therefore the object of a twin turbine housing Manufacture with reasonable effort and at reasonable cost from sheet metal.
  • a twin flow turbine housing according to the present invention may Have half shells, which consist of sheet metal.
  • a twin flow turbine housing according to the present invention may Furthermore, have a partition made of sheet metal
  • twin-flow turbine casing In a twin-flow turbine casing according to the present invention the two half-shells and optionally the partition wall are welded together.
  • the Partition and the half shells matched outer contours.
  • the outer contours of the half-shells lying in the parting plane bent edges have, which are welded together.
  • the half-shells have circular inner contours, at which lying in the parting plane bent edges are formed, which like the outer contours by means of notches and Fortroisn and welding are connectable.
  • twin-flow turbine casing In a twin-flow turbine casing according to the present invention the two inlet channels to a bypass line leading bypass openings and have that this bypass line is divided by an extension of the partition into two partial bypasses is.
  • FIG 1 is a conventional twin turbine engine casing for a turbocharger shown. Such twin housings are used in relatively strong engines and This is done by the exhaust gases of one group of cylinders from the exhaust gases of another group to separate from cylinders.
  • a cylinder may have a plurality of valves and that these valves a certain, for example, controlled by the camshaft Subject opening and closing cycle, with different exhaust valves of the same Cylinders open at different times to gases under different pressure to let out.
  • Fig. 1 is a computer drawing of a known modern one Twin turbine housing 1 for the two separate inlet channels 2 and 3 to one single turbine wheel, not shown, which, as explained above, one Implementation of turbochargers for more powerful engines corresponds.
  • FIG. 2 shows a twin-flow turbine housing (the term “twin”) on the presence of two inlet channels, at which, seen from the outside, only a single inlet duct appears to be present, but in reality is, as in Fig. 2 and 3, the inlet channel of this housing through a partition wall 18 in two axially adjacent parts 13a and 14a divided, thereby two operationally from each other completely separate inlet channels arise.
  • twin twin-flow turbine housing
  • the twin turbine housing of Fig. 2 consists of a double-walled structure, wherein the division into two separate inlet channels only affects the inner housing.
  • the Outer housing consists of two parts 12 and 15 which are connected together at 21.
  • the inner housing consists of two half shells 13 and 14 whose outer edges 20 and 20 ' are bent parallel to the parting surface A (see Fig. 3) and thus welded together can be.
  • the housing of FIG. 2 also has two connection flanges 11 and 16 for connection the catalyst or to the central housing of the turbocharger.
  • said partition Before welding, however, between the two half-shells 13 and 14 a Dividing wall 18 placed, said partition has an outer contour 18 ', with the mutually congruent outer contours 13 'and 14' of the two half-shells 13 and 14th matches.
  • edge portions 31 of the half-shells 13 and 14 may also have notches and extensions be formed as in the outdoor areas.
  • openings 17 and 17 ' are formed on the half-shells 13 and 14'. intended to complement each other in a circle and to divide Bypasses are provided, these openings to one, through a with the openings 17, 17 'welded tube 17 "formed bypass line 22 lead, by means of a Folding valve 19 by means of a controllable from outside the housing lever 23rd is lockable.
  • the partition wall 18 has a continuation 18 ', which projects into the bypass line and this follows up to the seat of the valve 19.
  • the bypass pipe 17 "also of two Half shells and the continuation 18 'of the partition wall 18 further extensions 30th have in notches of bent, axially extending edges of the half-shells of Tube 17 "intervene and are welded.
