Definitions
- the invention relates to an exhaust manifold, which comprises a flange part with a plurality of exhaust gas passage openings and an exhaust gas guide part fixedly connected to the flange part.
- 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 this exact positioning of the exhaust guide member on the flange is required.
- an exhaust manifold of the type mentioned in which the flange has a the exhaust gas passages exhibiting base member and a fixed to the exhaust guide member facing flat side of the base member stop plate as a stop for the exhaust guide part, said 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.
- 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.
- 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 is designed as a cast iron manifold.
- 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 disk form a support surface for the connection area along its entire circumference the exhaust gas guide part, so that in this way a gas-tight and stable welded connection between the exhaust gas guide part and the flange part 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 provided at an output side arranged, for example, two exhaust gas passage openings having 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-gas guide part 22 shown only in sections, consisting of an outer shell 24 and tubes 26 arranged inside it, which are connected to the flange part 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.
