Definitions

  • the invention relates to an exhaust manifold according to the features in the preamble of claim 1.
  • a generic Adgaskrümmer is out DE-A-43 39 290 known.
  • Such an exhaust manifold comprises a curved one End section, to which usually two Affix T sections.
  • the end section and the T-sections have a flange connection and a Pipe connection on.
  • the T-sections have a sliding seat nozzle.
  • the flange connection about the flange connection are the T-sections as well as the end section with a head flange to the engine-side connection of the exhaust manifold connected. To allow for expansion compensation, are the end portion and the T-sections each connected via sliding seats. For this overlaps the sliding seat of a T-section the pipe connection of the end section or the pipe connection an adjacent T-section end.
  • the T-sections of the exhaust manifold are made from a straight pipe section. For this is by hydraulic hydrofoil a substantially perpendicular to the tube axis projecting nozzle-shaped Bulge generated. This will be end opened by a saw cut. This way will the flange connection made.
  • the sliding seat nozzle is formed by one end of the exit tube.
  • the invention is therefore based on the
  • the prior art is based on the object, one in his Functionality improved exhaust manifold too create.
  • crux of the invention is the measure, the sliding seat nozzle by hydroforming at the outer radius of a pipe bend.
  • the output pipe is a bent pipe for use.
  • For the sliding seat neck is first at the outer radius of the pipe bend a bulge hydraulically generated. This is the end by a Saw cut open.
  • the saw cut oblique to the vertical transverse plane of the bulge or the pipe connection of a tee.
  • the flange connection of a T-piece can according to the technical or constructive requirements be executed long. This will both the attachment of the head flange as well as the assembly of the Exhaust manifold facilitated on the engine.
  • the length of a sliding seat can be kept relatively short.
  • a ratio of the length of the sliding seat to the diameter of a pipe bend of about 0.3 to 0.7, preferably 0.5, on. That way is one advantageous hydroforming production of Sliding seat neck possible without material thinning is to be feared.
  • the sliding seat between end portion and subsequent T-section or between the T-sections each other is guided by the merging of the respective sliding seat nozzle with the pipe connection guaranteed.
  • an exhaust manifold 1 is shown with a multi-channel inflow 2 and a single-channel outflow 3.
  • the exhaust manifold 1 essentially comprises three manifold components, namely a curved end portion 4, to which two Affix T-sections 5 and 6.
  • a curved end portion 4 to which two Affix T-sections 5 and 6.
  • T-sections 5 and 6 To make a stretch or length compensation of this pipe assembly in the exhaust system to allow the end section 4 and the T-section 5 and the T-section 5 and the T-section 6 each have a sliding seat 7 and 8 respectively connected with each other.
  • the bent end portion 4 has a Flange connection 9 and a pipe connection 10. Also the T-sections 5, 6 have a flange connection 11, 12 and a pipe connection 13, 14. Furthermore own the T-sections 5, 6 each have a sliding seat nozzle 15, 16.
  • Each T-section 5, 6 is a pipe bend 17, 18 made, on the wall of the sliding seat nozzle 15 or 16 is formed.
  • the saw cut is oblique executed, so that the ends 21, 22 of the sliding seat 15, 16 relative to the vertical plane accordingly slanting at an angle. Also the end 23 from the pipe connection 10 and the end 24 of the pipe connection 13 is bevelled. This way will an impairment of the flow conditions in the Elbow area 19 and 20 avoided.
  • the sliding seat 7 and 8 is formed by the fact that the sliding seat nozzle 15 of the T-section 5, the pipe connection 10 and the sliding seat nozzle 16 of the T-section 6, the pipe connection 13 of the T-section 5 end overlaps, wherein the sliding seat nozzle 15 and 16 and the pipe connections 10 and 13 each lie against each other in a media-tight manner. Accordingly, the diameter D 1 of the sliding seat nozzle 15, 16 by a corresponding amount greater than the diameter D 2 of the pipe connections 10 and 13th
  • the ratio of the length L s of a sliding seat stub 15, 16 measured along the center line ML to the diameter D of a pipe bend 17, 18, which corresponds to D 2 , is 0.5.
  • an exhaust manifold 1 For completing an exhaust manifold 1 is at its inflow 2 a not shown here Head flange fixed. To the head flange are the Flange connections 9 and 11 and 12 in diameter widened. At the outflow side 3 also closes via a sliding seat an exhaust pipe or intermediate pipe with an end head flange.
