Definitions

  • the invention relates to a flat gasket, in particular an exhaust-side gasket, for an internal combustion engine.
  • Surface pressure areas including first, second and third metal plates, wherein the first and second metal plates have beaded areas and the third metal plate is operatively connected to the first and second metal plates by crimping an inner area.
  • JP 02286859 A discloses a cylinder head gasket which has locking elements for receiving inserts in the region of media through-holes.
  • the invention has for its object to provide a gasket, in particular an exhaust-side gasket, for an internal combustion engine, in which the resulting by the joining of components supernatant can be compensated by simple means.
  • a flat gasket in particular exhaust gas-side gasket, for an internal combustion engine, formed by a sealing element provided with a recess at least one single-layered sealing element and a self-retaining and guiding with screw through-holes Carrier element, wherein the components carrying the sealing element with respect to the
  • Base surface of the support member project and the support member and / or the sealing element is at least partially provided with raised areas.
  • an embossed step for example a kind of half bead
  • the sealing element or the carrier element in the region of the at least two sealing surfaces for example engine block / cylinder head or
  • embossing eg hemispherical, rectangular, bead-shaped or the like
  • the thickened raised areas are adjusted in height approximately to the supernatant of the nose-shaped components.
  • the height compensation can thus be accomplished by individual, for example embossed raised areas in the support element and / or in the sealing element or by at least one circumferentially formed, in particular embossed bead. In this way, a second sealing line would be present with the
  • a stopper function (e.g., for beads next to stopper designs) can be realized.
  • any sliding movements that may occur can be distributed over a smaller area. This helps to minimize friction.
  • a kind of hybrid solution consisting of two different materials as needed, with only the relatively high temperature exposed, relatively narrow sealing area is formed by a sealing element of very high-quality temperature-resistant material.
  • a sheet of much cheaper material can be used, which only serves to realize the main installation thicknesses, if necessary, to connect a plurality of sealing elements together and make the entire seal assembled and fixable.
  • connection of the sealing element and the carrier element is advantageously achieved on a mechanical basis by clamping.
  • a flat gasket according to the invention can be used advantageously as
  • Suitable materials for the sealing element are in particular Ni-Cr-Fe alloys, wherein other temperature-resistant alloys can be used.
  • the support member may be made of a commercially available steel, for. B. cold strip exist.
  • FIGS. 1 and 2 show alternative embodiments of the flat gasket 1 according to the invention which can be used as an exhaust flange gasket.
  • the same components are provided with the same reference numbers.
  • a support element 2 for example consisting of cold strip, which is provided with a hole 3.
  • a sealing element 4 comprising a recess 4 ', out and about only hinted, formed out of the support member 2, lugs 5 with the
  • Carrier element 2 mechanically connected in the manner of a snap connection.
  • the noses 5 are widened in the opposite direction, so that some of them are positioned above and below the sealing element 4.
  • the sealing element 4 consists in this example of a temperature-resistant Ni-Fe-Cr alloy and is guided within the perforation 3 of the support element 2, such that it is easy to fix and assemble.
  • raised regions 7 in the form of half beads are embossed in the vicinity of screw through holes 6 in the carrier element 2.
  • raised regions 9 in the form of half beads are embossed in the edge region 8 of the carrier element 2 facing the sealing element 4.
  • FIGS. 4 and 5 show sections through connection variants between
  • FIG. 5 shows an alternative carrier element 2 as well as a likewise alternative sealing element 4. Due to the reshaping of the lugs 5, a protrusion outside the material thickness of the carrier element 2 or of the sealing element 4 can be formed in the guide regions of the sealing element 4, the overhang having a defined height h the base surface of the support element 2 protrudes.
  • the sealing element 4 is provided outside the free leg 11 with a beaded area 12.
  • Both the carrier element 2 and the sealing element 4 are punched out of suitable plate-like precursors, the perforation 3 of the carrier element 2 corresponding to the outer contour of the sealing element 4 used.
  • Sealing element 2 deformed back so that they - as shown in Figure 4 and 5 visible - rest on the free leg 11 of the sealing element 4.
  • FIGS. 4 and 5 various sections are shown by FIG. Recognizable is the respective peripheral bead 10 in the region of the support element 2.
  • the bead 12 is designed according to figure 5 of its height so that it is above the height h of the free end 11 of the sealing element 4 protruding lugs 5 is arranged.

Abstract

L'invention concerne un joint d'étanchéité plat (1), notamment un joint d'étanchéité du côté échappement, pour un moteur à combustion interne, formé par un élément d'étanchéité (4) au moins monocouche, pourvu d'un évidement, ainsi que par un élément de support (2) recevant et guidant ce même élément d'étanchéité avec un jeu, pourvu de trous de passage filetés (6), les éléments (5) guidant l'élément d'étanchéité (4) faisant saillie par rapport à la surface de base de l'élément de support (2) et l'élément de support et/ou l'élément d'étanchéité étant pourvu de zones au moins en partie en relief (7, 9, 10).
