Definitions

  • the invention relates to an oil pan for an internal combustion engine with a crank mechanism and a crankcase, wherein the oil pan is screwed to the crankcase of the internal combustion engine with a circumferential flange surface including a circumferential sealing surface, wherein the oil pan is designed as a carrier, as well as a first facing the crank mechanism, having the oil-containing side and a first side opposite the second side.
  • Such an oil pan is from the WO 02/22427 A2 known.
  • This oil pan has a parallel to the axis of the crankshaft of the internal combustion engine extending channel into which a shaft can be inserted.
  • This shaft is connected to a differential which is connected via lateral openings in the oil pan to the drive axles of the front axle of an agricultural implement.
  • the oil pan articulation devices for the wheels supporting the front axle wishbone are also known.
  • a similar oil pan is from the unpublished EP 1 688 595 A3 known. Also, this oil pan has a continuous channel through which an axle can be inserted. This channel basically corresponds to the channel of WO 02/22427 A2 , Below the channel, a recess is embedded in the oil pan, wherein in the recess casings and / or wiring, optionally closed by a lid, are used protected.
  • Another oil pan is from the DE 42 42 513 A1 known.
  • This oil pan is cast from an iron material and has a special feature on an oil filter mat, which separates the oil chamber of the crankcase of the oil chamber of the oil pan in one embodiment in the region of the flange. This is to clean the oil flowing back into the sump.
  • the invention has for its object to provide an oil pan for the use of an internal combustion engine in the field of agricultural technology.
  • the second side is formed as a hollow body and that a stiffening plate is attached to the hollow body to form a over the entire length of the oil pan extending through free space.
  • a stiffening plate is attached to the hollow body to form a over the entire length of the oil pan extending through free space.
  • the stiffening plate is attached to the lower part of a U-shaped free space.
  • the stiffening plate connected to the hollow body has a ribbing, whereby a weight saving while maintaining a large bending and torsional rigidity is achieved. In addition, this material can be saved.
  • the stiffening plate protrudes beyond at least one of the opposite end faces of the oil pan.
  • a seal is mounted between the oil pan and crankcase at least in a section. This prevents the formation of gaps between the sump and the crankcase in zones subjected to high loads due to bending and torsion, which then lead to leaks.
  • a circumferential bevel is attached to the sealing surface between the oil pan and the crankcase, whereby an applied before assembly of oil pan and crankcase sealant or a sealant during assembly forms a sealant wedge.
  • the oil sump has transverse ribs in the region of the flange surfaces. These are arranged so that they are present at an oil pan bolted to the crankcase below the crankshaft main bearings and according to their number.
  • the crank webs with crank pin and attached thereto connecting rods can dip into the interstices. This makes it possible to apply the mounting surface very close to the main crankshaft bearing cap, which leads to a further optimization of the bending and torsional rigidity and also improves the acoustic properties.
  • the transverse ribs are integrally molded with the oil pan. In this case, a good moldability of the mold by the previously described free spaces between the individual transverse ribs is possible.
  • the opposing end faces of the oil sump have mounting surfaces.
  • these attachment surfaces protrude beyond the longitudinal sides of the oil sump.
  • this projecting over the longitudinal sides part is supported by ribs.
  • the mounting surfaces are assigned a plurality of ribs arranged over the height of the respective longitudinal side, wherein the length of the ribs is formed in accordance with the load at the respective location.
  • the oil pan is cast from a ferrous material. As a result, a lighter production of the oil pan is given.
  • an oil suction line is poured into the oil pan.
  • the ⁇ lansaug Arthur opens in the region of an end face of the oil pan in the flange.
  • the oil suction line is led to the middle of the bottom wall of the oil sump and there has an inlet funnel with sieve.
  • the oil pan 1 according to Fig. 1 is designed for the operation of a self-igniting internal combustion engine, for example in the displacement range between 4 and 7 I, which in the use of the internal combustion engine z. B. is installed in a tractor.
  • the oil pan 1 is designed to be particularly resistant to bending and torsion for this application, wherein the weight of the oil pan 1 is located in the range of 270 kg. Due to the details of the oil pan 1 listed below this almost takes over the entire supporting function for the resulting in the installation of the internal combustion engine between the transmission and front axle in a tractor load. This makes it possible to use a crankcase from the normal automotive sector, which is lighter in weight and has no corresponding stiffeners.
  • the oil pan 1 is cast from a ferrous material and bolted via a flange 2 to the crankcase of the internal combustion engine using a corresponding sealing surface.
  • the flange 2 also has a circumferential inner slope 7.
  • a paste-like sealant is applied prior to assembly of the oil pan 1, which is pressed in the connection of the oil pan 1 and the crankcase in the slope 7 and seals them.
  • a corresponding recess is additionally provided in the flange 2.
  • the end faces 9a and 9b of the oil pan 1 also have the mounting surfaces 10a, 10b, 10c and 10d, on which the transmission and the front axle can be screwed. These screw-on surfaces 10a, 10b, 10c and 10d protrude laterally beyond the longitudinal sides 11a and 11b adjacent to the end faces 9a and 9b.
  • the mounting surfaces 10c and 10d are also supported via ribs 12 to the longitudinal sides 11a and 11b.
  • the mounting surfaces 10c and 10d each have three ribs 12, over which they are opposite to the side surfaces 11a and 11b.
  • an oil suction 13 is poured, which opens into the flange 2.
  • the at the second, designed as a hollow body side 3b of the oil pan 1 ( Fig. 2 ) attached stiffening plate 4 has a ribbing 5 to save weight while maintaining a high bending and torsional strength and is mounted as needed.
  • the weight of the stiffening plate 4 is in the range of 60 kg. It is also conceivable to perform this stiffening plate 4 as a solid plate.
  • Fig. 4 is another variant of the stiffening plate 4 can be seen.
  • the stiffening plate 4 in the direction of the transmission to be mounted on an extension with additional connection points.
  • the recess in the middle of the extension is taken for reasons of space for the universal joint located there.
  • An additional bore 14b in the stiffening plate 4 allows reaching the oil drain hole 14a of the oil pan 1.
  • a corresponding oil drain hole 16 is also mounted in the region of the longitudinal side 11a. However, this is provided for draining the required for the retraction of the internal combustion engine after assembly oil.
  • the longitudinal side 11b has a mounting surface 15 for an oil filler neck.
