Definitions

  • the invention relates to silencers with a deep-drawn inner shell and a deep-drawn housing shell according to the preamble of claim 1.
  • US 4,396,090 shows an exhaust gas silencer with an inner shell consisting of two superimposed metal sheets.
  • the inner shell plates are deep-drawn in such a way that an S-shaped exhaust duct is created, which is perforated at various points.
  • a housing shell is provided, which also consists of two superimposed, drawn sheets, which are placed on the inner shell so that chambers are formed between the inner shell and the housing shell.
  • Inner shell and housing shell each have a flange. All flanges are gas-tightly connected by a single weld.
  • DE-A-22 28 700 shows a silencer for boxer engines arranged at the rear of a vehicle.
  • the housing consists of two deep-drawn shell halves with a circumferential flange.
  • a partition divides the interior of the housing into two chambers.
  • the housing shell halves and the partition are connected by suitable connecting means, e.g. B. connected by a weld.
  • suitable connecting means e.g. B. connected by a weld.
  • openings, installation and add-on parts are provided on the intermediate wall, with the aid of which absorption chambers, expansion chambers and reflection chambers as well as Venturi nozzles are realized.
  • US 4 132 286, US 4 415 059, US 4 865 154 and US 5 012 891 disclose further silencers, consisting of a deep-drawn inner shell and a deep-drawn housing shell, which are placed on top of one another in such a way that all four metal sheets can be connected to one another in a gas-tight manner with a single circumferential weld seam in the area of the flanges. Deep, approximately V-shaped transverse folds are drawn into the housing shell, which touch the inner shell over the entire width of the housing and thus simulate the effect of the separate partitions of the muffler described at the outset, but with twice the material expenditure.
  • the flanges of the inner shell and the housing shell are connected to one another by a single circumferential weld seam.
  • This can lead to mechanical problems, since the metal sheets of the inner shell, which are in direct contact with the hot engine exhaust gases, heat up and expand considerably more than the metal sheets of the housing shell, which are cooled by the wind.
  • a weld seam leads to a change in the structure of the sheet metal material, which under certain circumstances results in an increased corrosion attack.
  • DE GB-A-1 012 463 shows silencers with a deep-drawn inner shell and a deep-drawn housing shell, the flanges of which are not connected to one another in a material-locking manner by means of a weld seam, but rather in a form-fitting manner by means of a fold.
  • the silencer described also has an intermediate wall, for which purpose the metal sheets of the inner shell are cut out and angled accordingly.
  • GB-A-632 013 shows a silencer with a deep-drawn inner shell and a deep-drawn housing shell, the flanges of which are placed one on top of the other.
  • the flange of the housing shell is wider than that of the inner shell, so that only the metal sheets of the housing shell are deformed during the mechanical connection by means of a fold.
  • the flange of the inner shell is clamped between the undeformed parts of the flange of the housing shell.
  • the flanges of the inner shell and the housing shell are no longer permanently connected to one another over the full length, so that theoretically there is the possibility that thermal tensions between the inner shell and the housing shell can be reduced. Due to the large contact area between the two flanges, however, considerable holding forces act; Compensatory movements are hardly to be expected. In addition, the gap between the sheets of the outer shell caused by the clamped inner shell causes manufacturing and corrosion problems. The correct centering of the inner and outer shell is also problematic with this construction, since a position control is no longer possible when the housing is closed.
  • the present invention is therefore based on the object of specifying a muffler of the type mentioned at the outset, in which the inner shell and the housing shell can carry out thermally induced compensating movements, while at the same time manufacturing is considerably simplified, accelerated and cheaper.
  • the flange of the inner shell only extends up to the housing shell.
  • the acoustic seal is guaranteed in any case if the gaps between the flange of the inner shell and the inner wall of the housing shell are small enough. This not only saves material, it also prevents corrosion.
  • For the flange connection of the housing shell only two sheets have to be deformed, which is possible with simple machines and tools. Since the inner shell is only connected to the housing shell at individual clamping points, the flange of the inner shell no longer has to be absolutely flat and smooth. Any drawing waves do not interfere. Equalization of thermal tensions is also easily possible. Different sheet thicknesses of the inner shell can be compensated for by making minor changes to the clamping beads.
  • the clamping beads of the one housing shell part are at a greater distance from the plane of the housing flange than the clamping beads of the other housing shell part.
  • the housing shell part with the shorter clamping beads acts as an adjustment aid for the exact positioning of the inner shell in the housing shell.
  • At least one intermediate wall is provided which has openings, in particular passages, for the exhaust gas-carrying channels.
  • the pipe-extending pipe sockets are molded onto the inner shell.
  • the pipe sockets are inserted through the openings in the partition. Thanks to this construction arises after closing the housing shell, a stable, self-holding installation part.
  • a second inner shell is preferably provided, the channels of which are also extended by pipe sockets.
  • the pipe sockets of the second inner shell are inserted into the first pipe sockets.
  • shaped beads are molded into the pipe socket, they position the intermediate wall during assembly, which according to an advantageous further development can be supported by a funnel-shaped widening of the pipe socket ends.
  • the interlocking pipe socket can be locked with the aid of these shaped beads.
  • a two-part partition is provided. At least one plug-in tab is formed on each of the separating surfaces.
  • the inner shell has corresponding plug-in slots into which the plug-in tabs are inserted.
  • retaining tabs can be formed on the dividing surface and bent at right angles. Sheet flaps are cut out of one of the inner shell sheets for fastening. The retaining tabs are then clamped between the second inner shell sheet and the sheet tabs. This fastening has the advantage that the inner shell does not have a continuous opening.
  • the built-in parts can be connected to one another in a form-fitting and / or material-fitting manner.
  • Fig. 1 shows a partially broken plan view of a first silencer.
  • a housing shell 10 consisting of two superimposed, deep-drawn sheets 17, 18 with an inlet connection 11 on one side and an outlet connection 12 on the other side.
  • the sheets 17, 18 of the housing shell 10 are provided with beads 15 in order to reduce the structure-borne noise emission.
  • the housing shell 10 has a circumferential flange 13.
  • the housing shell 10 In the interior of the housing shell 10 one can see two inner shells 30.1, 30.2 with a peripheral edge 40, each made from two sheets placed one on top of the other.
  • the inner shell sheets are deep-drawn in such a way that gas channels 31, 32, 33, 34, 35 are formed which generate an S-shaped gas flow.
  • a conventional partition 20 can be seen, which is placed in the housing shell 10 and holds the inner shells 30.1, 30.2.
  • the edges 40 are Inner shells 30.1, 30.2 dimensioned such that they only touch the inner wall of the housing shell 10 in the region of the flange 13. The edges 40 are therefore not clamped between the flange 13. This task is performed by special clamping beads 16, which are shaped deeper so that the edges 40 have a sufficiently large contact surface.
  • the clamping beads 16 are located above and below the flange 13.
  • the distance between each pair of clamping beads is exactly matched to the thickness of the sheets of the inner shell 30.
  • the distances between the clamping beads 16 in the two housing parts to level 1 of the flange 13 may, however, be different.
  • the clamping beads 16 press from above and below onto the edges 40 of the inner shells 30.1, 30.2 and clamp them firmly.
  • the flange 13 acts like a strong spring.
  • Stabilizing beads 41 in the edge 40 of the inner shells 30.1, 30.2 increase the mechanical strength when the clamping beads 16 are far apart.
  • a special feature of the exemplary embodiment in FIG. 1 is that the second inner shell 30.2 does not extend over the full width of the housing shell 10. Rather, a separate pipe 36 completes the exhaust gas path to the outlet port 11 here.
  • the concept according to the invention is also used for silencers conventional pipes.
  • FIG. 2 shows the partial section II-II through the edge of the silencer of FIG. 1 in the area of a clamping bead 16.
  • the edge 40 of the inner shell 30 is resiliently fixed between an upper and a lower clamping bead 16.
  • the flange 13 of the housing shell 10 shows no gaps or cavities in which condensate could settle.
  • the flange 13 is positively closed by a fold 14.
  • FIG. 3 shows the partial section III-III through the edge of the muffler of FIG. 1 in the area of a bead 15.
  • the edge 40 of the inner shell 30 hardly touches the housing shell 10.
  • the beads 15 are shaped such that they do not fix the edge 40 .
  • Fig. 5 shows the partial section VV of Fig. 1 through partition 20 and inner shells 30.1, 30.2.
  • a part of the intermediate wall 20 can be seen, in which an opening 23 in the form of a so-called passage was made. Furthermore can be seen in cross section the end of the channel 31, which ends in a pipe socket 42.
  • This pipe socket 42 is inserted through the opening 23.
  • the intermediate wall 20 is held on one side by a shaped bead 44, on the other side by a funnel-shaped widening of the pipe socket end.
  • a second pipe socket 43 with a shaped bead 45 is inserted and locked.
  • This second pipe socket 43 is the end extension of the channel 34 in the second inner shell 31.2.
  • FIG. 6 shows the section along the line VI-VI through the first pipe socket 42.
  • FIG. 7 shows a comparable section along the line VII-VII through the second pipe socket 43.
  • the housing shell 10 corresponds to that of FIG. 1.
  • the inner shell 30 ' is in one part, the intermediate wall 20' in two parts.
  • An upper and a lower partition wall part 20.1, 20.2 can be seen.
  • three openings or passages 21 are provided for the channels 31, 32, 33 of the inner shell 30 '.
  • flaps 22.1, 22.2 between the openings.
  • the inner shell 30 ' has with these tabs 22.1, 22.2 corresponding plug-in slots 46 into which the plug-in tabs 22.1, 22.2 are inserted from above and below.
  • FIG. 9 This situation is shown enlarged in FIG. 9 in partial section.
  • a weld seam 24 optionally connects the two intermediate wall parts 20.1, 20.2 to one another and to the inner shell 30 ', which simplifies assembly and increases the strength.
  • FIGS. 10, 12, 13 show, as a cross section (FIGS. 10, 12, 13) and a top view (FIG. 11), an alternative fastening method for a half partition 20.3.
  • a sheet metal tab 47 is cut out of one of the two sheets 30.3, 30.4 of the inner shell 30 lying one on top of the other and slightly bent up.
  • Half the partition 20.3 has a retaining tab 22.3 which is bent at a right angle. This holding tab 22.3 is placed under the sheet metal tab 47.
  • the sheet metal tab 47 is then bent down and the retaining tab 22.3 is firmly anchored between sheet metal tab 47 and the lower inner shell sheet 30.4.
  • the inner shell 30 has no through opening, as is the case with the fastening method in FIGS. 8 and 9.
  • FIG. 14 shows a longitudinal section through a third muffler with a deep-drawn housing shell 51 and a deep-drawn inner shell 52, the peripheral edge 53 of which is held in place in the housing shell 51 by the retaining beads.
  • the housing shell 51 is closed again by means of a circumferential flange 54.
  • three partitions 55, 56, 57 are arranged so that Chambers 61, 62, 63, 64, 65 arise which, depending on the application, can be used as expansion, reflection or absorption chambers or as a Helmholtz resonator.
  • the partitions 55, 56, 57 are designed as half partitions, which are fastened to the inner shell 52 with the aid of the holding tabs described. Since the partition walls 55, 56 in the lower housing half no longer have to be aligned with the partition walls 57 in the upper housing half, the manufacturer of such a muffler has much greater freedom in acoustic tuning than in the conventional muffler designs.
