Definitions

  • the invention relates to an arrangement for guiding exhaust gases from an internal combustion engine with at least one end attached to a hollow structure Flange.
  • the hollow structure in question is constructed with two shells and has an outer jacket and an inner jacket.
  • the object of the invention is an arrangement with a tubular hollow structure for guiding exhaust gases from an internal combustion engine to show which while avoiding welding spatter in the inner jacket process-reliable and inexpensive to manufacture with one Flange is connectable.
  • the invention solves this problem by an arrangement with a tubular Hollow structure, in which the inner jacket flanges from the outer jacket is led out and with an outward flaring an end section of the outer tube encompasses the outside circumference.
  • the flare inserted into the flange together with the end section and on the Mouth of the side facing away from the hollow structure of the flange with this material connected.
  • the flange does not necessarily have to be solid, but can also be a sheet metal flange provided with a central passage his.
  • An advantage of such a flange is that the welding process with more even and less heat can be carried out, so that Risk of thermal distortions is reduced. This is particularly so then the case when the collar receiving the tubular hollow structure is approximately has the same wall thickness as the hollow structure. Lower reject rates with simultaneous improvement in manufacturing quality are possible.
  • Made of sheet metal Manufactured flanges also reduce mass use compared to massive executed flanges.
  • Another advantage is the increased fatigue strength of the arrangement according to the invention, because transitions from large wall thicknesses to very small wall thicknesses and largely avoided the associated voltage peaks become. Since the intended weld seam on the outer circumference along a larger radius, lower bending stresses occur Inner jacket on. This is due to the integration between the end section of the outer jacket and the flange additionally a stress-reducing Clamping.
  • the tubular hollow structure is not due to circular cross sections of the inner jacket and the outer shell limited, but it basically come oval or polygonal hollow structures are also possible.
  • the tubular Hollow structure can also be used for all exhaust gas lines, which can be coupled to other components via flanges. manufacturing technology can the flanges on a tubular as well also form a shell-like inner jacket. With a bowl-like Inner jacket is expediently before the flaring process added to a hollow structure, which is then connected to the flange and Outer jacket is connected.
  • the arrangement can of course take the form of an exhaust manifold depending on the number of exhaust outlets, several on the input side Have head flanges and end flanges on the output side.
  • Figure 1 shows in cross section the end region of an arrangement 1 for guidance exhaust gas of an internal combustion engine, not shown.
  • the Arrangement 1 includes a double-walled hollow structure 2 a load-bearing outer jacket 3 and an exhaust gas-conducting inner jacket 4.
  • the wall thickness of the outer jacket 3 is a multiple of the inner jacket 4.
  • the wall thickness of the inner jacket 4 is between 0.3 mm and 1 mm, while the wall thickness of the outer jacket 3 is between 1.5 mm and 2.5 mm.
  • An air gap 5 is present between the inner jacket 4 and the outer jacket 3.
  • the outer jacket 3 is in one Transitional section 7 tapered. Closes at the transition section 7 an end section 8 of the outer jacket 3 which is tapered in diameter, which is dimensioned such that it has the inner jacket 4 on its outer circumference contacted.
  • the inner jacket 4 extends on the mouth side 6 over the end section 8 of the outer shell 3 and is rearward through 180 ° to one in cross section U-shaped flange 9 is formed.
  • the flange 9 encompasses in its Course initially arcuate and at a distance the end face 10 of the end section 8 and then extends parallel to this away from the mouth 6 parallel in the direction of the conical transition section 7 of the outer jacket 3.
  • the end face 11 of the flange facing the transition section 7 9 lies in a common radial plane RE with a flow opening 12 surrounding collar 13 of a flange 14.
  • the flange 14 is designed as a sheet metal flange, with the central throughflow opening 12 having the surrounding collar 13 is made by a sheet metal forming process.
