Definitions

  • the invention relates to an exhaust manifold, which comprises a flange with a plurality of exhaust gas passages and a fixedly connected to the flange exhaust guide member, wherein the flange has a the exhaust gas passage openings exhibiting base member and a fixed to the exhaust guide member facing flat side of the base member stop disc as a stop for the exhaust guide member and wherein a contour of the stop disc at least partially corresponds to the contour of the exhaust guide member in the region of its connection to the flange.
  • the flange part comprises a plurality of superimposed, connected by brazing plates.
  • a circular opening is provided, wherein the diameters of the openings in the various plates are chosen so that a sleeve of an exhaust guide can be inserted into the openings of one part of the plates and seated on another, adjacent to the cylinder head plate whose Opening is slightly smaller than the diameter of the sleeve.
  • exhaust manifolds which may be formed in particular as so-called air-gap manifold
  • a exhaust gas guide serving exhaust gas guide member is gas-tight and mechanically strong connected to the flange.
  • the exhaust guide member is welded to the flange. To comply with predetermined manufacturing dimensions for this exact positioning of the exhaust guide member on the flange is required.
  • a stop disc On one of the exhaust guide part facing flat side of the base member so a stop disc is also attached, which prevents lateral displacement of the patch on the flange exhaust guide member. This makes it possible to position the exhaust guide member without further aids in a predetermined position by the stop plate and then to weld.
  • the outer edge of the stop disk is set back in particular with respect to the edge of the base element and forms an outer contour which at least in sections corresponds to the inner contour of the exhaust gas guide part.
  • the exhaust guide member is slid over the stopper disc in this embodiment, i. the stop disk is after positioning with its outer edge at least partially on the inside of the exhaust gas guide part. This results in a good accessibility of the attachment areas to be welded.
  • stop disc inversely by the provision of one or more central recesses so that the formed by the recesses inner contour of the stop disc at least partially corresponds to the outer contour of the exhaust guide member.
  • the stop disc on one or more exhaust gas passage openings, which cover the exhaust gas passage openings of the base member.
  • the exhaust gas flow can be passed through the stop disk.
  • the stop disc is screwed to the base member.
  • Such a screw allows due to the provided in the stop plate and the base member holes or threaded holes exact positioning of both parts against each other.
  • the stopper plate may be welded to the base member.
  • centering holes and / or pins may be provided in the base member and / or the stop plate.
  • the stop disc is a stamped part.
  • the base member may advantageously be a stamped part. Such stampings are very economical to manufacture.
  • the base element is a lamellar flange composed of a plurality of lamellar disks arranged in parallel.
  • Such lamellar flanges have a high strength and are also inexpensive to manufacture.
  • the exhaust manifold may be an air gap insulated manifold having an inner portion and an outer portion spaced therefrom through an air gap.
  • the inner part consists in particular of a plurality of tubes, one end of which opens into the exhaust gas passage openings, while the outer part is preferably formed as a shell part with two half shells.
  • the exhaust gas guide part is connected to the base element and / or the stop disk by a welded connection, in particular a laser welding connection.
  • the edges of the stop disc form over its entire circumference a bearing surface for the connection region of the exhaust gas guide member, so that in this way a gas-tight and stable weld between the exhaust guide member and the flange is achieved.
  • the flange is a cylinder flange for attachment to the cylinder head of an internal combustion engine.
  • a corresponding stop disc can also be arranged at an output side, for example, two exhaust gas passage openings having provided flange of the exhaust manifold.
  • a flange 8 is shown for an exhaust manifold according to the invention. It comprises a base element 10 which has three exhaust gas passage openings 12 for the passage of the exhaust gases emerging from the internal combustion engine. Furthermore, eight arranged in the vicinity of the circumference mounting holes 14 are provided, can be performed by the corresponding screws for attachment to a cylinder head, not shown, of an internal combustion engine.
  • a stop plate 16 is arranged, which is smaller than the base member 10, so that it projects beyond the base member 10 at any point laterally, but rather a distance to the outer edge of the base member 10 remains and no mounting hole 14 is covered.
  • the stop disc 16 also has three exhaust gas passage openings 12 'which have the same diameter as the exhaust gas passage openings 12 of the base element 10 and are aligned with these in an assembly position.
  • a screw connection 18 is provided, through which the base member 10 and the stopper plate 16 are interconnected.
  • Fig. 2 shows an exhaust duct part 22 shown only in sections, consisting of an outer shell 24 and disposed therein pipes 26, which are connected to the flange 8.
  • the stop disk 16 is, as already mentioned above, so connected to the base member 10, that the exhaust gas passage openings 12, 12 'of both parts are aligned.
  • the outer shell 24 is pushed completely over the stop disk 16 and abuts the base element 10 at the end.
  • the inner contour of the outer shell 24 corresponds to the outer contour of the stop plate 16, so that both abut each other in the illustrated mounting position.
  • Outer shell 24 and stop disk 16 are connected to each other by a over the entire circumference of the outer shell 24 extending laser weld joint 28.
  • the end sections of the tubes 26 extend through both exhaust gas passage openings 12, 12 ', so that a projection 30 is formed on the side of the flange section 8 facing away from the stop plate 16.
  • the tubes 26 are fastened to the base element 10 in the region of the projection 30 by a laser welding connection 28 'extending over the circumference of the exhaust gas passage opening 12.
  • the continuous laser weld joint 28 'prevents the entry of exhaust gases into an air gap 32 between the tubes 26 and the outer shell 24.
  • the base element 10 may have a thickness of 6 mm and the stop disk 16 a thickness of 2 mm.
