Definitions

  • the invention relates to an oil cooler oil pump device for an internal combustion engine according to the preamble of claim 1.
  • An oil pump module which unites an oil pump, an oil cooler and an oil filter in a common structural unit.
  • the oil cooler sits in a plastic housing, the oil pump is laterally flanged to the plastic housing.
  • the oil pump module is pressed on the plastic housing against the crankcase of an internal combustion engine and is driven by this.
  • Such oil pump modules suck oil from an oil pan and convey it to the oil cooler and an oil cooler downstream oil filter, from where the cooled and purified oil is passed to the lubrication points of the engine.
  • the invention has for its object to reduce pressure losses in oil cooler oil pump devices for internal combustion engines.
  • the oil cooler and the oil pump are disposed outside of an oil pan placed below the crankcase of the internal combustion engine.
  • Oil pump and oil cooler are located on different sides of the wall of the oil pan and are directly connected via a connecting pipe. Due to the integration of the oil pump in the oil pan, the oil in the oil sump of the oil sump oil is sucked in the shortest possible distance from the oil pump and passed through the connecting pipe to the oil cooler on the outside of the oil sump.
  • the connecting tube preferably extends through a recess in the oil sump wall, wherein in principle also embodiments are contemplated in which the connecting tube is arranged in the region of the end edge of the sump wall.
  • the oil cooler is conveniently located directly on the outside of the sump to minimize the distance the oil must travel from the sump to the oil cooler.
  • the attachment of the oil cooler on the outside of the oil pan is preferably carried out via a flange plate on the oil cooler, through which the connecting pipe is passed.
  • the connecting tube thus extends through the wall of the oil sump and through the flange plate.
  • the oil pump has a suction pipe for sucking the oil from the oil sump of the oil pan, wherein the oil suction pipe is advantageously integrated into the housing of the oil pump and formed integrally therewith.
  • the oil pump housing and the oil suction tube are preferably made of a light metal such as aluminum. In the oil suction can be arranged in the region of the free end face an oil screen.
  • the ⁇ lsaugrohr preferably projects obliquely down into the oil sump, so that the sucked oil is conveyed by the pump unit of the oil pump obliquely up to an outlet port, which is connected to the connecting pipe.
  • the connecting tube which is preferably rectilinear, extends in particular horizontally between the oil pump and the oil cooler. In this way, it is ensured at least when driving on a level road that from the oil pump no conveying work to overcome the height in the connecting pipe must be expended.
  • the oil pump is preferably designed as a gear pump, in principle, other pump designs come into consideration.
  • a mounting flange is integrally formed with the oil pump housing, which is connected to a ⁇ lwannenwandung on the inside of the oil pan, in particular in the region of the tub bottom or a shoulder formed in the oil pan. But it is also possible to attach the mounting flange on the inside of the oil sump wall, on the outside of the oil cooler is arranged.
  • an oil cooler oil pump device 1 which comprises an oil cooler 2 and an oil pump 3 and in or on an oil pan 4 a Internal combustion engine is arranged.
  • the oil cooler 2 is attached to the outside of a boundary wall 5 of the oil pan 4, the oil pump 3 is located in the interior of the oil pan 4.
  • Via a connecting pipe 6 which is integrally formed with the oil cooler 2 and which extends horizontally through the boundary wall. 5 extends through the oil pan 5, the oil cooler 2 and the oil pump 3 are interconnected.
  • the oil cooler 2 has a flat flange plate 7, with which the oil cooler 2 is attached to the outside of the boundary wall 2.
  • the flange plate 7 also receives the connecting pipe 6, which is in particular formed integrally with the flange plate 7.
  • fastening elements 8 are arranged, which are designed as screws and with which the flange plate 7 is fixed to the outside of the boundary wall 5.
  • the flange plate 7 In the mounted position, the flange plate 7 is parallel to the outside of the boundary wall 5, wherein in a regular driving situation with a flat surface, the flange plate 7 extends in a vertical plane, so that the perpendicular to the plane of the flange plate 7 protruding connecting pipe 6 assumes a horizontal position.
  • This has the advantage that on level ground no height difference over the connecting pipe 6 must be overcome.
  • the oil pump 3 in the interior of the oil pan 4 has an oil suction pipe 9, which is in particular formed integrally with the oil pump housing, wherein the oil pump housing and oil suction pipe 9 preferably from a Alloy metal such as aluminum.
  • the free end of the ⁇ lsaugrohrs 9 is directed to the bottom 10 of the oil pan 4, which forms an oil sump with oil absorbed therein in operation.
  • an oil sieve 11 is integrated into the oil suction pipe 9.
  • a mounting flange 13 is formed, via which the oil pump 3 is to be connected to the oil pan 4.
  • fastening eyes 14 are integrally formed fastening eyes 14 for receiving fasteners, such as screws, with which the mounting flange is to be attached to a raised shoulder 15 of the oil pan.
  • the paragraph 15 extends angularly in the interior of the oil pan, the top of the shoulder 15 is below, ie at an axial distance from the end face of the peripheral boundary wall of the oil pan, but at the same time higher than the bottom 10 of the oil pan.
  • Fig. 1 is integrally formed with the oil pump housing 12 of the gear pump designed as an oil pump 3 on the connecting pipe 6 side facing a pipe socket 16 which is designed as an elbow and in the mounted position ( Fig. 2 ) is connected to the connecting pipe 6.
  • the pipe socket 16 equalizes the angle between the obliquely downwardly directed ⁇ lsaugrohr 9 and the horizontal connecting pipe 6; this angle is in an angle range between 0 ° and 90 °, for example at 45 °.
  • the free end face of the pipe socket 16 is provided with an enlarged diameter, in which the connecting pipe 6 can be inserted.
  • the oil pump 3 is adjacent to the boundary wall 5, on the outside of the oil cooler 2 is arranged. This has the advantage that relatively short tube lengths for the connecting tube 6 and the pipe socket 16 are sufficient.
