Definitions

  • the disclosure relates to an oil pan.
  • the disclosure relates to an oil pan with an integrated shielding of the oil located in the oil pan from an oil pump or movable elements of the oil pump.
  • the US patent US 9,376,942 B2 relates to a baffle structure in an oil pan.
  • the baffle plate is used to separate an interior of the oil pan into a crankcase side and an oil chamber side.
  • An oil guide element is also provided.
  • the oil guide element comprises an inlet section and a parallel section.
  • the inlet portion extends to a bottom surface of the oil pan.
  • the inlet section has an inlet port for lubricant at a lower part of the inlet section.
  • the parallel portion extends from the inlet portion in a direction substantially parallel to the baffle to introduce the lubricant from the inlet portion to the oil pump.
  • the baffle plate has an opening that corresponds to the parallel section of the screen.
  • the parallel section of the oil guide element is arranged in such a way that it closes the opening in the baffle plate.
  • At least one disadvantage of existing oil pans can be seen in the fact that oil can be foamed by a drive pinion of the oil pump. Foamed oil can lead to the failure of individual components of the internal combustion engine.
  • an oil pan of an internal combustion engine in particular for a motor vehicle, is designed to accommodate an oil pump, the oil pump being driven by a pinion, the pinion being arranged at least partially below an oil surface of an oil pan volume within a pinion volume in an installation position of the internal combustion engine in the motor vehicle is which by a partition is separated from the oil pan volume, so that engine oil whirled up by the pinion does not lead to foaming of engine oil which is located in the oil pan volume .
  • Engine oil collects in the oil pan.
  • the engine oil is used for lubrication and for heat transport within the internal combustion engine and is pumped through elements of the internal combustion engine by the oil pump.
  • the elements include coolers, heaters, filters, a camshaft, a camshaft adjustment unit (Camphaser), a crankshaft and the like.
  • the pinion is often driven by a chain.
  • the pinion generates entropy in the engine oil due to its rotation.
  • the pinion volume refers to a space in which the pinion can rotate freely. When the teeth of the pinion hit the oil surface, it is foamed. The foamed oil does not get into the oil pan volume due to the partition wall. In this way, for example, an oil can also be used which has at least a reduced proportion of potentially environmentally harmful additives to avoid foam formation.
  • At least a part of the partition is integrally formed on the oil pan.
  • the partition wall continues in a shielding plate arranged on the oil pump.
  • the partition wall thus extends as far as a shielding plate which is connected to the oil pump or can be connected to it.
  • At least the shielding plate is pot-shaped and has a flange area on the outside circumference, with which the shielding plate can be connected to the oil pump.
  • the pinion is therefore largely separated from the oil pan volume.
  • the partition wall in its installation position mounted with the oil pump has two openings through which two strands of a drive of the pinion can be guided.
  • the pinions are mostly driven by chain drives or the like.
  • the strands of the drive run through said openings. This allows necessary Connections between the oil pan volume and the pinion volume are restricted to a minimum, especially since the openings are above the oil surface in the ready-to-use installation position when the oil fill quantity is in accordance with the regulations.
  • the partition wall extends from a geodetically underneath base area of the oil pan.
  • the pinion volume is partially separated from the rest of the oil volume of the oil pan, at least on an underside.
  • the partition wall can be manufactured in one piece with the oil pan in a primary molding process (die casting or sand casting process).
  • the partition accommodating the pinion, ends flush with an inner wall arranged around the base area.
  • the pinion volume is partially separated from the rest of the oil volume of the oil pan, at least on the lateral outsides.
  • the partition has a recess in the area of an oil drain opening arranged in the oil pan.
  • engine oil can gelan conditions from the pinion volume into the oil pan volume and vice versa.
  • the recess serves to ensure that the pinion volume can run completely empty when the engine oil is drained during an oil change.
  • the recess is located centrally above the oil drain opening when viewed in a vertical axis Z of the vehicle.
  • an oil drain plug which is inserted into the oil drain opening, can penetrate into the recess and close it as far as possible.
  • a certain fluid exchange between tween the pinion volume and the oil pan volume is quite desirable so that the oil in the pinion volume ages to the same extent as the other motor oil in the internal combustion engine and so that it is regularly filtered and cooled.
  • oil should completely run out of the oil pan and the pinion volume when the oil is changed. Due to the arrangement of the oil drain screw below the partition, both volumes run empty when the oil drain screw is opened.
  • an oil pump which has a drive pinion which drives a delivery unit arranged in the oil pump, the pinion being designed to accommodate a pinion volume partially enclosed by a partition.
  • Fig. 4 the oil pump without the oil pan with the partition, which is connected on the drive side with a housing of the oil pump.
  • FIG. 1 shows an oil pan 1 of an otherwise not shown internal combustion engine, in particular special for a motor vehicle, also not shown.
  • the oil pan 1 is designed to accommodate an oil pump 2.
  • the oil pump 2 is ben by an only indicated pinion 3 is driven.
  • the pinion 3 is in a suitable installation position of the internal combustion engine in the motor vehicle at least partially below an oil surface 4 of an oil pan volume 5.
  • the pinion 3 is at least in the area below the oil surface 4 within a pinion volume 6.
  • the pinion volume 6 is spatially through a Partition wall 7 separated from the oil pan volume 5.
  • the pinion 3 can be driven by a chain drive, not shown. It whirls up the engine oil. Because of the partition wall 7, the engine oil whirled up and foamed by the pinion 3 cannot get into the rest of the oil pan volume 5. Without the partition 7, the engine oil which is located in the oil pan volume 5 could foam up.
  • FIG. 2 shows the oil pan 1 according to Figure 1 without the oil pump. It can be seen that at least part of the partition 7 is integrally formed on the oil pan 1.
  • the oil pan 1 is a part produced in a casting process, which is to be produced as far as possible without encapsulated cores.
  • the oil pan 1 should be demoldable from the casting tool. With demouldable is meant that the oil pan 1 can be removed from a cast core, not shown, after the casting process.
  • the partition wall 7 with rounded chamfers 14 extends orthogonally from a base surface 11 of the oil pan 1.
  • the chamfers 14 correspond to permissible casting radii.
  • the partition 7 has corresponding rounded chamfers 12 and easily demolded, slightly inclined walls 13.
  • the partition 7 extends in one piece from an inner side 10 of an outer wall 17 of the oil pan 1.
  • the bevels 14 between the partition 7 and the inside 10 are provided with castable or demoldable radii.
  • the partition 7 has a recess 15 in the area of the oil drain opening 9 arranged in the oil pan 1 for draining and renewing the engine oil.
  • the recess 15 is located in a vehicle vertical axis Z, viewed in the middle, exactly above the oil drain opening 9.
  • FIG. 3 it can be seen that the partition wall continues in a shielding plate 16 arranged on the oil pump 2. Accordingly, the shielding plate 16 has, on its side facing the partition 7, an edge 22 that is flush with the partition 7.
  • the shielding plate 16 is pot-shaped.
  • the outer circumference of the shielding plate 16 has a flange area 18 with which the shielding plate 16 can be connected to the oil pump 2.
  • the shielding plate 16 has two openings in its installation position mounted with the oil pump 2, through which two strands of a drive of the pinion 3 can be guided.
  • the drive is usually formed by a chain.
