Definitions

  • the invention relates to an exhaust manifold according to the features in the preamble of claim 1.
  • exhaust manifolds are also part of the state of the Technology by punching, bending and welding sheet metal are formed. These are so-called Half-shell manifold. Each bowl is one of one Sheet steel stamped board ahead, which is then under half of the inflow channels and the outflow channel be deformed. The two shells will then to form the manifold housing with its edges placed on top of each other and then along the edges welded. Ultimately, a head flange becomes on the inflow side and a pipe flange on the outlet side Welding attached.
  • Such an exhaust manifold is e.g. out EP-A-0 582 985.
  • the head flange serves to attach the exhaust manifold to the engine block while the pipe flange for the connection of the exhaust gases Exhaust pipe is provided.
  • the invention is based on the prior art Task to create an exhaust manifold that formed by punching, bending and welding sheet metal is, however, a lower manufacturing cost with improved Exhaust gas routing required.
  • the essential aspect of the invention is in that the housing of the exhaust manifold is now complete is made from a single board. For this is to provide only one follow-up tool, which initially the board is stamped from a steel sheet and this board then formed into the manifold housing.
  • the manifold housing points both with regard to the inflow channels and the outflow channel one resulting from the bending geometry Cross section on.
  • the particular advantage of the invention lies in the comparison to the well-known half-shell manifold significantly cheaper Construction with significantly less Weld length. Exhaust gas routing can now also be targeted be optimized. As a result of the cheaper Construction is also with reduced use of materials Weight of the exhaust manifold has been reduced. Its firmness is nevertheless larger because the weld seam length is reduced has been.
  • the inflow channels and the outflow channel have a rectangular cross section. Cross sections that differ from one another are also conceivable. Furthermore, the inflow channels and / or the outflow channel have a U-shaped cross section.
  • a particularly advantageous embodiment of the invention is seen in the features of claim 3. After that are some baffles bent in a V-shape with the predominant part of their longitudinal edges in carrier slots the circuit board bent to the manifold housing and welded along the carrier slots.
  • the V-shape of the baffles enables the corresponding Curvature of the side walls an optimal fluidic Design of the inflow channels with a corresponding one Transition into the outflow channel.
  • the exhaust manifold 1 in Figures 1, 3 and 4 is an exhaust manifold for called a six-cylinder engine.
  • the exhaust manifold 1 comprises a manifold housing 2, a head flange 3 on the multi-channel inflow side and one at right angles to the head flange 3 extending pipe flange 4 on the single-channel Outflow side.
  • the exhaust manifold 1 Baffles 5, 6, 7 on that together with the manifold housing 2 three inflow channels 8, 9, 10 and one outflow channel 11 form.
  • the inflow channels 8, 9, 10 are in alignment adapted recesses 12, 13, 14 in the head flange 3, while the outflow channel 11 with a recess 15 in Pipe flange 4 is aligned.
  • a blank 16 is stamped from a steel sheet.
  • the board 16 has one of three web sections 17, 18, 19 existing central web wall 20 and laterally the leg sections 17, 18, 19 lying leg walls 21, 22 or 23, 24 or 25, 26.
  • the leg walls 21-24 are with starting from the thigh margins 27-30 Carrier slots 31-38 provided.
  • leg walls 21-26 are then around the bend lines 39, 40 at an angle ⁇ of 90 ° to the web sections 17, 18, 19 folded.
  • the longitudinal edges 41 are rounded ( Figure 4).
  • leg walls 23 and 24 together with the web section 18 by the between the two Web sections 17, 18 bending line 42 folded so far, that the leg edges 43, 44 of the leg walls 23, 24 to the leg edges 45, 46 of the leg walls 21, 22 come across.
  • the manifold housing 2 already has the configuration according to FIGS. 1, 3 and 4.
  • the baffle 5 is curved in an arc and is curved with the Leg edges 53 of the leg walls 21, 22 welded, which the leg edges 27, 28 of the leg walls 21, 22 connect to the U-shaped end edge 54.
  • the other two illustrated in FIGS. 5 and 6 stretched Baffles 6, 7 each consist of three Surface sections 55, 56, 57 and 58, 59, 60, respectively middle surface sections 56, 59 narrower than the outer Surface sections 55, 57 and 58, 60 are dimensioned.
  • the width B of the outer surface sections 55, 57 and 58, 60 corresponds to the outer width B1 of the manifold housing 2, while the width B2 of the middle surface sections 56, 59 of the inner width B3 of the manifold housing 2 corresponds ( Figures 1 and 4).
  • the guide plates 6, 7 corresponding to the carrier slots 31, 33 or 32, 34 or 35, 37 or 36, 38 in the leg walls 21-24 curved and bent into a V-shape and then with their edges 61, 62 or 63, 64 or 65, 66 and 67, 68 of the outer surface sections 55, 57, 58, 60 inserted into the carrier slots 31-38.
  • the V-shaped middle surface sections 56, 59 only spacer elements between the leg walls 21 and 22 or 23 and 24.
  • 70 is in dash-dotted lines still indicated that the inflow channels 8, 9 and 10th and / or the outflow channel 11 also has a U-shaped cross section can have.
