Definitions

  • the invention relates to an oil pan according to the preamble of claim 1.
  • crankcase and oil sumps of internal combustion engines arranged thereon tend to vibrate during operation, which cause undesirable noises.
  • the acoustic behavior is unsatisfactory, particularly in the case of relatively long-length internal combustion engines which have an essentially flat and plate-like oil pan.
  • the invention has for its object to reduce the noise emission of an oil pan with simple means.
  • connection of the flat part of the oil pan to the overlying bearing seats that receive the crankshaft significantly reduces the sound radiation from the oil pan and shifts the excited frequencies upwards into a subjectively less disturbing area.
  • longitudinal vibrations that occur during operation of the internal combustion engine, in particular of middle storage chairs, are advantageously effectively prevented.
  • the sound radiation is essentially reduced by the fact that the flat and plate-like bottom of the oil pan is connected to the storage chairs in the area of medium storage chairs, ie in the area of the greatest vibration amplitude of the floor.
  • the originally large-area floor is thus separated into several smaller sub-areas with regard to sound radiation, which vibrate at a higher frequency with a lower amplitude.
  • the longitudinal vibrations of the storage chairs are prevented by the rigid connection by means of the supports to the bottom of the oil pan.
  • the supports are advantageously arranged transversely to the longitudinal direction of the internal combustion engine in parallel planes which also accommodate the storage chairs.
  • a U-shaped design of the supports, in which the parallel legs are formed as one piece with the oil pan as screw-receiving pipes, allows the pan to be manufactured in a simple manner suitable for production.
  • the oil pan receives additional stability from ribs arranged between adjacent supports on the bottom of the oil pan, which at the same time serve as an oil plane for the lubricating oil thrown off the crank mechanism and can be used for this purpose against the direction of rotation of the crankshaft.
  • a diagonal arrangement of these ribs between adjacent supports further increases the stability.
  • the screws penetrating the pipes and connected to the storage chairs are accessible at all times for installation.
  • An oil pan 1 of a multi-cylinder internal combustion engine has a flange 2 lying in a connection plane A, with which the oil pan 1 is detachably held on a horizontally divided crankcase of the internal combustion engine, not shown.
  • the oil pan 1 is bounded laterally by walls 3 running in the longitudinal direction L of the internal combustion engine, between which extends a plate-like flat bottom 4 which is inclined with respect to the plane A and which at one end of the oil pan 1 merges into the deep part formed as an oil sump 5.
  • Supports 6 are arranged in parallel planes E1, E2 running transversely to the longitudinal direction L and extend from the floor 4 to this plane A perpendicular to the connection plane A. These supports 6 are U-shaped, the two parallel legs 7 being designed as pipes 8.
  • the pipes 8 have bushings 9, by means of which the bottom 4 is screwed with screws, not shown, to bearing blocks 10 of the crankshaft 11, the bearing blocks 10 being delimited by the connecting plane A, so that the distance H between the bottom 4 and the plane A is bridged by the pipes 8.
  • Each pipe 8 of a support 6 is connected to a diagonally opposite pipe 8 of an adjacent support 6 via a rib 12 formed integrally with the bottom 4. Ribs 13 arranged adjacent to the rib 12 each hold a pipe 8. Outside the supports 6, further ribs 14 are arranged on the floor 4.
  • the stability of the oil pan 1 is further increased by transverse support ribs 15 running transversely to the ribs 12, 13, 14 and the pipes 8.
