Definitions

  • the invention relates on the one hand to a closure cover for a housing with a shaft extending through the cover, in particular for crankshaft and transmission housings in motor vehicles, with a dynamically acting seal for the shaft and a statically acting seal for the cover flange surface, the dynamic seal consisting of at least one vulcanized to the cover, possibly spring-loaded, elastic sealing lip and the static seal consists of axially protruding, elastic sealing strips vulcanized into recesses in the cover flange surfaces.
  • the invention relates to a closure cover, as is used in particular in crankshaft housings of motor vehicle engines with a flanged oil pan, whereby in addition to the dynamic sealing of the shaft, two flange surfaces that meet at an angle of usually 90 ° are statically sealed, one flange surface of which is radial for a tight connection with the The crankcase and its other flange surface run axially for a tight connection to the oil pan.
  • a cover of the aforementioned type is known.
  • This cover consists of an aluminum die-cast body on the inner circumference has an elastic sealing lip for sealing the continuous crankshaft, while sealing limits in the form of elastic sealing strips vulcanized into grooves in the flange surfaces are provided for sealing the radial flange surface to be connected to the crankshaft housing and the axial flange surface to be connected to the oil pan.
  • a connection to the dynamically acting sealing lip is established by additional radial and axial grooves with sealing strips, whereby the vulcanization of the sealing elements is particularly simple, in particular in the transfer or compression molding process.
  • the closure lid consists of a profile-drawn sheet metal body with a substantially cup-shaped cross section and has three radial surfaces lying in different axial planes, the bottom surface of the tin pot being the radial flange surface for connection to the housing to be closed, but axially in stages offset second radial surface for receiving the sealing strips and the third radial surface is used to connect the dynamic sealing lip.
  • the central radial surface which can also be formed when the tin pot is pulled, is used to hold and fasten the sealing strips. Due to the stepped design of the tin pot base, the incompressible material of the sealing strip can also move radially in the installed state.
  • the cover is drawn from a sheet metal body with an approximately cup-shaped cross-section, with in the area of the inner circumference of the radial flange surface and in the area of the transition Angesstelle the radial flange surface to the axial flange surface of the tin pot is profiled in such
  • This third, recessed radial flange surface thus allows in a simple manner the known connection of an uninterrupted sealing strip running in both planes with an angular configuration in the region of the radial and axial flange surfaces meeting at 90 °.
  • the graded profiling of the sheet metal body cross section contributes to a substantial stiffening of the same, so that it can be produced from relatively thin sheet metal and is thus much lighter in the finished state than the known aluminum die-cast body.
  • the sealing strips are vulcanized essentially in the transition region of the rounded edges of the recessed surface of the tin pot.
  • the rounding of the edges resulting from the pulling of the sheet metal body offers a relatively large base area for connecting the sealing strips, which should be made relatively narrow with their axially or radially projecting area and with a rectangular cross section, which is conducive to the sealing function.
  • the sealing strip running parallel to the axial flange surface emerge from it at an acute angle to the radial or axial flange surface.
  • FIGS. 1 to 4 serves to seal a crankshaft housing of a motor vehicle engine with an oil pan that can be flanged from below.
  • the sealing cover is shown in its commercially available form.
  • the sealing cover consists of a pot-shaped sheet metal body 1 which, to seal the crankshaft passing through in the installed state (not shown), a dynamically loaded sealing ring 2 made of elastomer material and statically acting sealing strips 3 and 4, also made of elastomer material, which merge into one another, having.
  • the sheet metal body has three radial flange surfaces, the sealing ring 2 on the flange surface 5, while the sealing strips 3 and 4 in the region of the flange surface 7 that is axially recessed relative to the flange surface 6 are vulcanized.
  • the latter are connected to the sheet metal body with a relatively broad base area in the rounded sheet metal body region between the radial surfaces 6 and 7 and extend axially with a relatively narrow web 8 which emerges from the flange face 6.
  • the sheet metal body 1 with the flange surface 6 is braced against the crankshaft housing (not shown) with the aid of screws which can be inserted through the holes 9.
  • This flange connection is sealed by means of the sealing strip 3, in particular its axially projecting web 8.
  • the sealing strip 4 which - as can be seen in FIG. 2 - emerges at an acute angle both from the radial flange surface 6 and from the axial flange surface 10 for sealing the oil pan (not shown) which can be screwed against the crankshaft housing from below.
  • two nuts 11 are welded into the cover, see FIG. 1.
  • FIG. 5 shows a simplified, annular closure cover made of a sheet metal body 1 ⁇ , the sealing strip 3 ⁇ being profiled in the area of its surface with two concentric and annular beads 13, 14.
