Definitions

  • the invention relates to an outer housing for an exhaust muffler for internal combustion engines, comprising at least one pipe section which has a seamlessly transitioning base at one end and at least one connecting piece which also proceeds seamlessly.
  • the exhaust muffler according to the invention should preferably be used on motor vehicles.
  • the bottom and the connecting piece extending therefrom are formed in one piece on the pipe section in question in that the relevant end of the pipe section is tapered by round hammers.
  • the round hammering can be carried out over a mandrel or also without a mandrel as cold forming or hot forming.
  • This known outer housing has several disadvantages.
  • the shaping of the pipe socket by means of rotary hammers not only requires expensive tools, but is also labor-intensive and complicated.
  • the floor can only be tapered outwards up to about 45 ° so that the creation of other shapes for the floor, e.g. a bottom extending substantially perpendicular to the tube axis, with the known manufacturing method is excluded.
  • the tube section with bottom and connecting piece consists of a wrought aluminum alloy and is extruded in one piece.
  • the solution according to the invention allows the production of the pipe socket with bottom and connecting piece in one operation. This reduces both the manufacturing time and the manufacturing costs compared to the known designs.
  • the extrusion process also allows any design of the bottom and the connecting piece or the connecting piece.
  • the latter can also be arranged anywhere on the floor.
  • the connecting pieces can namely protrude both inwards and outwards and / or be arranged centrally or eccentrically with respect to the pipe axis.
  • the wrought aluminum alloys are highly corrosion-resistant, so that the outer housing according to the invention is characterized by a long service life.
  • the outer housing according to the invention can be made relatively thin-walled.
  • the screw connections for the base and cover, which are otherwise required for multi-part outer housings, are no longer required.
  • the outer housing according to the invention is characterized by a low weight.
  • An exhaust gas silencer for internal combustion engines has become known (DE-OS 26 53 732), in which the tubular housing consists of an extrusion process. manufactured aluminum hollow profile.
  • the two front housing covers are designed as separate components that have to be screwed to the tubular basic housing.
  • the outer housing of the known exhaust silencer then consists of several differently designed components that must be assembled. This makes the known construction more expensive.
  • the pipe sections can have a round, oval or rectangular cross section and cooling fins can be formed in one piece on the outer surface of the pipe sections.
  • the outer housing according to the invention can consist of at least two pipe sections which are aligned with one another. Both end pipe sections can be designed according to the invention. But it is also conceivable that an end or middle tube section is only cylindrical.
  • the outer housing according to the invention consists of at least two pipe sections placed flush against one another, it is advantageous that the pipe sections cannot be removed by folding or welding are interconnected.
  • an intermediate base is crimped in the joining plane of two pipe sections placed one against the other. This does not necessarily have to be made of an aluminum alloy, but can also consist of steel.
  • the outer housing according to the invention consists of only one pipe section, it is expedient that the other end of the pipe section is closed by a cover, which in turn has one or more connecting pieces.
  • the connection between the cover and the pipe socket can be made as desired and e.g. be a screw connection.
  • the wide design options of aluminum extrusion allow the shape of the floor to be chosen as desired. This can be conical, curved or flat.
  • At least one receiving part directed into the interior of the tube is integrally formed exclusively or in addition to at least one connecting piece projecting outwards at the bottom of the tube section.
  • This receiving part is used to fix a perforated tube arranged in the interior of an exhaust silencer, between whose outer wall and the inner wall of the outer housing a noise-absorbing material is sandwiched.
  • the described receiving part is expediently designed as a pipe socket.
  • a plurality of such connecting pieces and pipe pieces can also be provided.
  • the inner pipe socket is designed in such a way that subsequent deformation, e.g. training in the form of a venturi tube is possible.
  • the outer housing for an exhaust gas silencer for internal combustion engines consists of two essentially identical tubular sections, which are denoted overall by 10.
  • Each tube section 10 comprises a cylindrical part 11 which merges seamlessly into a base 12 at one end. From this floor 12 also a connector 13 goes off seamlessly.
  • Each of the pipe sections 10 with bottom 12 and connecting piece 13 consists of a wrought aluminum alloy and is integral in the ' Extrusion process manufactured.
  • the two pipe sections 10 are permanently connected to one another by a fold 14.
  • a tube 21 is inserted into the connecting piece 13, which has passage openings 22 and over which a perforated tube 23 is pushed.
  • a sound-absorbing material 24 is introduced between this perforated tube 23 and the inner wall of the tube sections 10.
  • Fig. 2 shows a slightly modified end of a pipe section 10. Then goes from the bottom 12 of the pipe section 10 not only to the outside of the connecting piece 13, but also inwardly a pipe socket 15, wherein the connecting piece 13 and the pipe socket 15 are aligned. Such a shape can easily be produced in the extrusion process. While an exhaust pipe 25 is pushed onto the connecting piece 13, the pipe piece 15 carries the perforated pipe 23.
