Definitions

  • the invention relates to an oil pan for an internal combustion engine according to the preamble of claim 1.
  • an oil pan which has a arranged in the region of a gear flat and arranged in the region of a crankcase of an internal combustion engine deep bottom portion.
  • the oil pan is open to the crankcase and gearbox.
  • the edge of this oil pan has a sealing area, through which the oil pan is sealed against the crankcase and the transmission.
  • DE 39 11 014 A1 describes a cylinder block with an oil pan and an insert, which is jammed in the sealing area between the oil pan and cylinder head.
  • Object of the present invention is to provide an oil pan with a particularly reliable and good seal against that housing part or those housing parts on which or to which the oil pan is attached.
  • the rigidity of the oil pan is significantly increased.
  • the oil pan without loss of rigidity at least partially flatter than previously executed, which allows an increase in space and, for example.
  • ground clearance In the case of a motor vehicle, ground clearance.
  • the rigidity is again significantly increased by the oil pan comprises at least one arranged between opposite sealing portions web or pin, which additionally connects the stabilizing part with the bottom portion. This counteracts a strength-reducing bulging of the stabilization part and also of the bottom section, and also noise-causing vibrations of the stabilization part and of the bottom section are reduced.
  • the production is simplified if the sealing region has a shoulder to which the stabilizing part is attached.
  • a particularly favorable frictional connection between the stabilizing part and the bottom section is created when the sealing region has a groove into which the stabilizing part engages.
  • the stabilization part can also be attached to the sealing area in a blunt manner. In this case, no changes are required at the sealing area itself.
  • the sealing region can also be arranged on the stabilizing part, wherein, however, attention must then be paid to a good sealing by a corresponding connection of the stabilizing part to the bottom section.
  • the web and / or pin may be integrally formed on the stabilizing part or on the bottom portion.
  • the production of the stabilizing part or the bottom portion of the oil pan is simplified.
  • the stabilizing part there may be oil calming passages extending from an upper side of the stabilizing part into a space between Stabilization and ground section lead. This gives the stabilizing part an additional oil calming function. Their effect is further improved if at least one oil calming channel runs in sections in a web, because this extends the oil calming channel.
  • a development of the oil sump according to the invention is that at least part of an oil suction pipe is integral with the stabilizing part.
  • the stabilizing part receives another function, namely the holder or receiving a ⁇ lsaugrohrs. This also has advantages in the manufacture of the oil pan, since the separate handling of at least this part of the ⁇ lsaugrohrs deleted.
  • At least a part of an oil suction pipe can also run in a web. This also reduces the number of parts to be handled during assembly of the oil pan according to the invention.
  • connection of the stabilizing part with the bottom portion comprises a tongue and groove connection.
  • the rigidity of the stabilization part is increased if it has a zig-zag folding and / or waveform at least in sections. Also, the flow of oil can be influenced in a desired manner.
  • a filling part which has a zig-zag fold and / or wave shape or is made of a porous material.
  • Such a filling part likewise prevents or at least impedes buckling of the bottom section and / or the stabilizing part and thus increases the strength of the oil sump.
  • the area of the stabilizing part projecting beyond or into the deep section serves for holding at least one functional element, for example an oil suction pipe and / or an oil filter.
  • the stabilizing part has an additional function, and it can be dispensed with a separate support of the ⁇ lsaugrohrs and / or the oil filter. This facilitates handling during assembly in the oil pan and thus reduces the manufacturing costs.
  • the oil sump comprises an oil planer, which is formed at least in part by the stabilizing part.
  • the stabilizing part fulfills a further additional function, so that it is possible to dispense with a corresponding separate part, which simplifies handling during assembly of the oil sump.
  • the oil pan comprises an oil planer, which is at least partially formed by a arranged in the installed position in the region of the deep portion of the oil pan part, which is mounted in the installed position on the crankcase or a corresponding housing. This also serves to simplify the assembly of the oil pan according to the invention.
  • a portion of an oil suction pipe and / or an oil filter is attached to or integrally formed on the part of the oil planer arranged in the region of the deep portion of the oil pan.
  • the oil planer thus receives an additional function, namely the mounting of a ⁇ lsaugrohrs or an oil filter. This eliminates parts to be handled separately, which makes the manufacture of the oil pan easier and cheaper.
  • FIG. 1 An oil pan carries in FIG. 1 Overall, the reference numeral 10. It is screwed to a crankcase 12 of an internal combustion engine from below.
