Definitions

  • the invention relates to a vehicle silencer according to the preamble of claim 1.
  • the invention particularly relates to a transverse rear silencer.
  • Silencers as far as the production of the peripheral wall is concerned, are subdivided into two types of production, namely shell-type silencers and coil-type silencers.
  • shell-type silencers In the shell construction two deep-drawn sheets are joined together at the edge, while in the winding construction, a sheet is wound and closed by a no, then the insert and the outside floors are pushed laterally and then closed axially by folding.
  • the invention relates to a vehicle silencer in wound construction.
  • the gas inlet and the gas outlet are provided on the end walls, optionally on opposite sides or on the same side. It is also known to drive the gas inlet through a peripheral wall in the muffler, wherein the inlet pipes are welded to the peripheral wall with its end.
  • a muffler is known with an inlet and an outlet tube, both tubes are welded to a housing.
  • the US 4,022,291 A describes a muffler with an elongated, tubular housing forming a chamber.
  • An inlet tube leads into the interior of the chamber.
  • Several outlet pipes extend into the chamber and are surrounded by a respective can-shaped housing for improving the damping.
  • the cans are attached to the housing.
  • the US 3,776,366 A1 shows a silencer with a tubular housing.
  • An inlet tube is attached to the housing via a mounting flange.
  • the invention relates to an exhaust muffler, in which the connection between the pipe associated with the peripheral wall and the peripheral wall itself is more stable and less stressed.
  • the tube is thus not exclusively on the peripheral wall with the Exhaust muffler is connected, but is therefore stored at two spaced locations on and in the exhaust muffler. This also has the advantage that a second outside of the exhaust silencer previously provided vehicle-mounted storage near the peripheral wall can be omitted.
  • the attachment of the tube to the insert is not limited to an axial sliding bearing, which would only act radially to the longitudinal extension of the tube. Rather, the tube is firmly connected in its axial as well as in its radial direction with the insert.
  • the attachment of the tube to the insert by mechanical forming.
  • This type of attachment is less susceptible to corrosion than welding.
  • Other advantages over welders are the lower distortion of the components and the higher strength.
  • a mechanical forming can also be achieved from the inside of the tube, which is advantageous in that the pipe end is not accessible from the outside with previously closed peripheral wall.
  • the tube and the insert are usually pressed together.
  • the insert according to the preferred embodiment has at least one inner end wall for forming a chamber to which a retaining wall is attached, to which in turn the pipe is attached.
  • the retaining wall is fastened between two opposite end walls.
  • a preferred embodiment provides that the insert, to which the pipe is attached, is held in the longitudinal direction of the muffler only through the pipe. This preferred embodiment allows unimpeded thermal expansion of the insert in the axial direction (axially relative to the muffler axis).
  • the invention provides, for example, to attach the two projecting into the interior of the tubes at their free end pieces on two adjacent inserts.
  • FIG. 1 is a transverse, double-flow vehicle exhaust silencer, hereinafter referred to as vehicle muffler or just silencer shown.
  • vehicle muffler has an outer housing, which consists of opposite outer end walls 3, 5 and a peripheral wall 7, which in FIG. 1a is shown simplified.
  • the peripheral wall 7 is wound from a sheet metal part, wherein the outer longitudinal edge 9 is welded to the inner edge portion after winding. Alternatively, the two longitudinal edges may also be connected to each other by folding.
  • the silencer interior can be divided into two halves, namely a left and a right half. These halves are separated by end walls 11, 13, which are axially spaced from each other.
  • the left half has further, provided with flow openings 15 end walls 17, 19, which divide the left half in a total of three chambers 34, 36, 37.
  • An outlet tube 21, 39 in each half is provided with openings, not shown, on the outer periphery and protrudes through the end walls 3, 5, 17 and 19 therethrough, wherein it is at least welded to the end wall 3 and 5 respectively.
  • a retaining wall 23 is arranged made of sheet metal, which is welded to the end walls 11, 19.
  • the end wall 19 is connected via further connecting pipes 25, 27 of different cross-section with the end walls 3 and 17.
  • the retaining wall 23 has, as in FIG. 2 Good to see, cruciform embossments 29, which increase their stability.
  • An inlet pipe 31 protrudes through an opening in the peripheral wall 7 (see FIG. 2 ) and is welded to this over the entire tube circumference.
  • the inlet pipe 31 extends further into the silencer interior and also protrudes through a relatively precisely fitting opening in the retaining wall 23 (see also FIGS. 4 and 5 ).
  • the retaining wall has in the region of the passage opening for the inlet pipe 31 a sleeve-shaped edge 33 produced by plastic deformation.
  • FIGS. 1 and 2 It can be seen that in the left half of the inlet pipe 31 ends shortly after passing through the retaining wall 23. At a distance from it starts a connecting pipe 27 with a 90 ° -Abwinklung.
  • the tube 27 extends through aligned flow openings 15 of the end walls 17, 19th
  • the inlet pipe 31 of the right strand opens into a thicker connecting pipe 35, which leads into a middle chamber 37.
  • the outlet pipe 39 of the right-hand strand also opens into this middle chamber 37.
  • further tubes 25 are provided between the end walls 5, 13, 17, 19 in the right-hand strand, with corresponding end walls carrying the reference numerals already introduced for the left half. Some of the tubes 25 may be formed as non-gas flowed stabilization rods between the end walls.
  • outlet tube 39 protrudes through the outer end wall 5 and is welded thereto.
  • outlet pipes 21, 39 are outside so-called tail pipes 41 inserted.
  • These also have an outwardly facing flared end into which so-called intermediate pipes 43 are inserted.
  • the inserts are made consisting of the inner end walls and the connecting tubes and the retaining wall 23 and connected to the outer end walls 3, 5.
  • a sheet is wrapped around a core and, as in FIG. 1a represented, welded.
  • the openings for the passage of the inlet pipes 31 are already provided.
  • the inserts from both sides are axially inserted into the peripheral wall 7, the so-called shell, and the end walls 3, 5 are connected to the jacket 7.
  • the inlet pipes 31 are inserted through the openings in the peripheral wall 7 until they also protrude through the corresponding openings in the retaining walls 23.
  • the inlet pipes 31 are attached to the associated retaining walls 23, by mechanical forming.
  • a tool for example a type embossing tool or circulating rollers, penetrates into the interior of the corresponding tube 31.
  • the tube 31 is eg on the entire Pipe circumference in the region of the sleeve-like edge 33 plastically deformed outwardly to form a groove, wherein the edge 33 is deformed.
  • Tube 31 and retaining wall 23 are connected in this way axially and radially positively and non-positively connected and pressed.
  • FIG. 4 is also the bead-like extension 53, which has formed in the slender wall 23, easy to recognize.
  • tube 31 and retaining wall 23 can also be pressed together in segments, as in FIG. 5 shown.
  • the tube 31 has been pressed outward only on a few sections 55, which are circumferentially spaced from each other, forming beads 53 in the edge 33.
  • FIG. 6 is schematically an alternative e in the FIGS. 4 and 5 shown forming shown.
  • the difference to the embodiment of FIGS. 4 and 5 is that the tube 31 axially seen before and behind the edge 33 plastically outwardly, ie in the radial direction, is deformed. In this case, the edge 33 is not deformed. The resulting beads secure the edge 33 in the axial direction. It is also possible, the pipe 31 only partially, similar to in FIG. 5 shown to deform before and after the edge 33.
  • Another possibility of forming is, e.g. the end of the tube 31 projecting through the opening to crimp end-to-end, resulting in a securing in an axial direction.
  • FIG. 3 essentially corresponds to the embodiment shown in the figures described so far, so that in the following only the differences must be addressed. Functionally identical parts receive the previously introduced reference numerals.
  • this transverse exhaust muffler is provided with a wound peripheral wall 7.
  • the muffler is single-flow and has only one central inlet tube 31.
  • This inlet tube 31 is, as in the aforementioned embodiments, welded to the peripheral wall 7 and projects through this and through the retaining wall 23 therethrough. After the retaining wall 23, the tube 31 is widened, namely on the circumference at a plurality of spaced-apart portions 55. A sleeve-like edge 33 may be omitted here, which otherwise also applies to the aforementioned embodiment.
  • the central insert in the silencer interior consists of the end walls 11, 19, the retaining wall 23 and connecting pipes or corresponding rods 25. This insert is positioned in the axial direction A only through the inlet pipe 31.
  • the outlet pipe 39 protrudes with a sliding fit through the end wall 19.
  • the outlet pipes 21, 39 can also pass through the peripheral wall 7.
  • the retaining wall 23 is preferably aligned at right angles to the longitudinal axis X of the inlet tube 31 passing through it.
