Definitions

  • the invention describes a housing closure cover for internal combustion engines of at least one metallic layer, in particular sheet metal, with a statically acting, vulcanized seal in the cover flange surface, which projects axially beyond the housing closure cover.
  • EP 0 528 104 B1 discloses a housing closure cover for a crankshaft housing. It is presented a deep-drawn sheet metal body with cup-shaped cross-section, for connection to the sealed housing, the bottom surface has two axially offset from each other arranged radial surfaces, being arranged for connection to the sealed housing in the first radial surface through holes for screws and staggered contrast staggered second radial surface for receiving a vulcanized, statically acting sealing strip is used.
  • the heat shield described herein consists of two superimposed metallic sheets between which a serrated sheet is arranged, the spikes are locally injected differently deep into the surfaces of the base plates, so that the serrated sheet acts as a spacer for the sheets.
  • the generated air chambers act as insulators.
  • the preferably used material is aluminum, which reflects the heat radiation particularly well due to its metallic luster.
  • Other heat shields use this material-specific property, so in EP 0 934 809 a heat shield is described consisting of two materials arranged flush one above the other.
  • the first layer is a heat-reflecting metal foil, preferably aluminum or stainless steel, which is bonded to a second thermally insulating plastic.
  • the aim of the efforts described here is to protect the add-on components in the area of the exhaust system from radiation. In particular, with housing closure covers malfunction of the sealing strip could lead to the escape of oil and the engine would be destroyed.
  • the invention has for its object to extend the described prior art and to develop a housing closure cover which acts as a heat-reflecting and protects the sealing strip from overheating.
  • the housing closure cover is designed as a heat shield, so that the seal is protected against overheating against external heat radiation.
  • the housing cover is formed so that it has a heat-reflecting effect. This is realized primarily through the use of aluminum for the production of the housing cover.
  • the invention describes the spacing by means of a serrated sheet which is arranged between the sheets. The serrated sheet, depending on the position of the heat source, is pressed into the sheets of the housing cover at different depths.
  • the housing cover is the dimensionally accurate deep drawing and superimposition of the sheets.
  • the individual sheets are designed differently in height, so that when joining creates a cavity between the two sheets.
  • the sheets lie directly above each other in the area of the lid flange surface.
  • the cavity thus created can be filled with an insulating material or remain empty.
  • deep drawing it is now possible to give the sheets any shape.
  • the shaping may be due to space or due to necessary stiffening (eg beads, ribs).
  • the sheets can also be arranged isolated from each other via brackets, webs, profiles, the insulation material is arbitrary.
  • the housing cover must not be made of two sheets arranged one above the other, it is provided in the invention to produce the heat shield of two different materials, which lie directly above each other.
  • the heat radiation source facing material is a heat radiation reflecting material.
  • FIG. 1 shows a section through a housing closure cover 1 according to the invention with a seal 2, a serrated sheet 3, an inner 4 and an outer 5 sheet.
  • the serrated sheet 3 is pressed so far that it rests directly against the inner 4 and outer 5 sheet metal.
  • the serrated plate 3 serves for spacing the inner 4 and outer 5 plates so that cavities 8, 8 'are formed.
  • the seal 2 is vulcanized in an axial surface lying in the direction of the curvature 7 of the housing closure cover radial surface 9.
  • the spikes 10 of the serrated plate 3 engage in the inner 4 and outer 5 plate and thus stabilize the construction of the housing cover. 1 FIG.
  • FIG. 2 shows an embodiment according to the invention of the housing cover 11 with an insulation layer 12 in section.
  • the insulating layer 12 is arranged between the inner 13 and the outer 14 plate of the housing cover 11. Wherein the outer sheet 14 is always a heat-reflecting sheet.
  • the sheets 13, 14 of the housing cover 11 are spaced apart by the insulating layer 12 and lie flat in the region of the Deckelflansch measurements 15 and the seal 16 on top of each other.
  • an embodiment according to the invention of the housing cover 1 with an insulation layer 18 is shown in section in FIG.
  • the insulation layer 18 disposed between the inner 19 and outer 20 metal sheet is air.
  • beads 21 can be incorporated into the sheet.
