Definitions

  • the invention relates to flanges for attaching an exhaust manifold to one Engine block according to the preamble of claim 1.
  • Exhaust manifold that exits from the cylinder outlets of the engine block collect hot exhaust gases and to the exhaust system, consisting of exhaust pipes, catalytic converter and muffler, were originally made as castings manufactured. Compare for example US 28 47 819.
  • the flange forms with whose help the exhaust manifold is screwed to the engine block, the largest Problems. First of all, the flange must be able to be attached in a gas-tight manner. Farther , modern engine construction dictates certain shapes and thicknesses of the flanges what results in a high financial outlay when casting.
  • pipe elbows are increasingly used. These consist of Elbow pipes of suitable length and shape, which are welded to a flange.
  • the flanges be gastight and have a high inherent rigidity. The high ones also cause problems Temperatures and the associated thermal expansion differences. you compare in this respect DE-OS 15 76 357, one for each cylinder outlet has its own small flange.
  • EP 0 178 430 B1 discloses an exhaust manifold with a flange that is composed of four relatively thin sheet metal plates, which at least partially Stainless steel can exist.
  • the metal sheets are punched individually, are made with the help of Dowel holes and dowel pins stacked exactly and finally brazed.
  • the top sheet metal plate is provided with a passage in which a manifold pipe can be welded. This flange is intended for two cylinder outlets.
  • the present invention has for its object one of several Sheet metal composite flange indicate the advantages of the known Constructions
  • Cylinder 1 + 4 a pair of manifolds and cylinder 2 + 3 a pair of manifolds can be one of the two Pairs of manifolds are completely assembled except for the overlap points.
  • the screws of the Already assembled elbows can then be attached to the pipes mounting manifold are covered. It results in comparison to single flanges unevenly distributed screw positions in the solution according to the invention a relatively even screw pattern, which is a prerequisite for a good Is gastight.
  • the sliding of the Contact surfaces can be improved by a suitable coating.
  • Fig. 1 shows purely schematically an exhaust manifold in side view, which can be done with the help of Stud 4 and nuts 5 are screwed to an engine block 3.
  • the flange is there from two sheet metal plates 1, 2 one above the other, which is based on FIGS. 2 and 3 in more detail should be described.
  • exhaust pipes 6 are welded to an exhaust system (not shown).
  • Fig. 2 shows the first layer 1 of sheet metal plates 11, 12, 13 for producing a flange for the exhaust manifold.
  • the sheet metal plates 11, 12, 13 lie next to one another at a distance.
  • the Fastening openings in particular of the two outer sheet metal plates 11, 13 are extremely unevenly distributed.
  • FIG. 3 shows the flange after applying a second layer 2 of sheet metal plates 21, 22, 23 to the lowest position 1. This creates three partial flanges, the Mounting holes 211 ... 214, 221 ... 225; 231 ... 234 of the upper layer 2 with the corresponding mounting openings of the lower layer 1 are aligned. They also s worn Cylinder outlet openings 421 ... 424 of the upper layer 2 with the cylinder outlet openings of the lower layer 1.
  • the partial flanges can be compensated in the area of the contact surfaces of thermal expansions slide against each other.
  • flanges can be, which consist of a board and several partial flanges and on the Overlap points have a corresponding contour, or that of more than two Sheet metal boards are manufactured and which consist of more than three partial flanges.
