Definitions

  • the invention relates to a method for producing a vehicle silencer with a housing which comprises opposite outer end walls and a winding jacket formed by winding a sheet metal part, and at least one silencer insert in the interior of the housing. Furthermore, the invention relates to a vehicle silencer itself.
  • An above-mentioned vehicle muffler is for example from the EP 1 888 891 B1 known, in which exhaust pipe connections extend through the peripheral wall into the silencer interior and are positively secured by mechanical deformation of the silencer insert.
  • a tool In order to enable mechanical deformation of the exhaust pipe connections inside the muffler, a tool must be introduced from the outside into the interior of the exhaust pipe connection and deform the exhaust pipe connection from the inside. Such a method is expensive and therefore expensive. Due to the deformation with the tool in the interior of the exhaust pipe connection only short pipe sections can be attached as exhaust pipe connections to the vehicle muffler, which in turn must be connected to the exhaust pipes.
  • the EP 1 627 997 A1 shows a silencer, in which an opening is formed in man Tell, followed by pipes on the inside. These tubes extend through partitions in the muffler. Another tube is welded from the outside to the through hole of the shell or at a collar edge of the through hole.
  • the post-published EP 2 354 483 A2 shows a muffler, in which an inlet tube is welded to a collar at the passage opening in the jacket and projects up to a support wall in the interior of the muffler.
  • the support wall has an opening with a conically shaped edge on which the cone-shaped tapered inlet tube rests on the inside.
  • the object of the invention is to provide a simple and cost-effective method for producing a vehicle silencer, in which at least one tube extends through the peripheral wall into the silencer interior, in wound construction and such a cost-effective silencer.
  • the inventive method for producing a vehicle muffler mentioned above comprises the method steps that a tail pipe is inserted through a recess in the winding shell on or in a support plate of the muffler insert or connected to the support plate inner tube to create a connector.
  • the tailpipe is placed on a socket of the support plate.
  • the tail pipe is inserted into an opening of the support plate, in which case the free end of the tail pipe is axially movable at least in the direction out of the housing to the support plate.
  • the tailpipe is thus first positioned radially in the plane of the support plate and then secured while maintaining the connector produced on the winding jacket.
  • the pipes of an exhaust system can be connected directly to the vehicle silencer.
  • the tailpipe it is possible for the tailpipe to have a taper at the pipe end, preferably a conical taper, with the tailpipe being inserted with the taper into the opening of the support plate. In this way, on the one hand, the positioning of the tailpipe be facilitated, and on the other hand, a tolerance compensation between the pipe diameter and the diameter of the opening of the support plate is made possible in a simple manner.
  • the tailpipe has a widening, preferably a conical widening, at the pipe end.
  • the support plate may have an opening, in the edge region of the support plate has an at least partially extending in the direction of the recess of the winding jacket nozzle, wherein the tail pipe is placed on or in the nozzle.
  • the neck has a, preferably conical, taper in the direction of the recess of the winding jacket, which also serves the play-free radial fixation of the free end of the tailpipe.
  • the muffler insert may have an inner tube which projects through the opening of the support plate and is connected to the support plate, wherein the inner tube forms the at least partially extending in the direction of the recess of the winding mantle.
  • the tailpipes can be connected directly to inner tubes of the vehicle silencer, whereby different tube lengths are made possible to influence the acoustic properties of the vehicle silencer.
  • the nozzle substantially corresponds to the inner radius of the tail pipe, so that the plug connection forms an axial sliding seat. In this way, the free end of the tail pipe is axially movable.
  • the support plate can form a stop for the tailpipe upon insertion of the tailpipe, so that the support plate limits movement of the tailpipe in the axial direction. In this way, the support plate forms a stop when inserting the tailpipe and thus enables an axial positioning of the tailpipe on Shulldämpfertoxins. This is easy to realize, especially with a conically shaped part.
  • the tailpipe is fastened to the winding jacket by welding.
  • the tailpipe has a collar and the tailpipe is fastened via the collar to the winding jacket. In this way, manufacturing tolerances between the outer cross section of the end tube and the recess of the winding jacket, through which the tail pipe is inserted, can be compensated in a simple manner.
  • the invention further relates to a vehicle silencer, which is produced by a method described above, with a housing which comprises opposite outer end walls and a winding jacket formed by winding a sheet metal part, at least one silencer insert and at least one tail pipe.
  • the tailpipe extends through the winding jacket into the silencer interior, wherein the tailpipe is attached to the winding jacket and is connected by a plug connection with a support plate of the silencer insert.
  • the tailpipe is placed on a neck of the support plate or in an opening of the support plate, wherein the free end of the tailpipe is axially movable at least in the direction out of the housing to the support plate.
