Definitions

  • the invention relates to an internal combustion engine according to the preamble of claim 1.
  • a generic internal combustion engine is known from DE-OS 26 18 241.
  • the internal combustion engine described in this document is generally rigid and low-noise.
  • a strut system is provided which is attached to the outside of the internal combustion engine.
  • the bearing arrangement for receiving the crankshaft is connected to the crankcase via a solid apron, which has only a small recess.
  • This design has the disadvantage that the internal combustion engine as a whole is very heavy due to the massive connection of the bearing arrangement to the crankcase.
  • the invention has for its object to provide an internal combustion engine that is lightweight with low noise emissions from the moving parts.
  • the stiffeners are designed as cross girders. This embodiment has proven to be favorable in terms of high rigidity and also in terms of low noise emissions.
  • the cross girders advantageously extend from the connection region of the bands with the bearing base body to the opposite crankcase wall running between the bands.
  • the stiffeners can be connected in a central area between the bearing base body and the crankcase on the belts and on the crankcase wall connecting the belts. Both training courses have proven to be favorable in terms of weight and noise emissions.
  • the cross-sectional area of the stiffeners is 0.3 times to 0.7 times the cross-sectional area of the strips.
  • 0.5 times the cross-sectional area has proven to be particularly favorable.
  • the bearing base body and / or the bands are connected to the crankcase bell by means of ribs.
  • This design makes the overall system even stiffer and at the same time enables a further reduction in the thickness of the crankcase bell walls as well as the bearing arrangement as a whole.
  • the ribs together with the bearing base body form an at least approximately rectilinear connection plane between the two sides of the crankcase bell.
  • further ribs can be provided, which extend to an oil pan flange of the crankcase bell and, if appropriate, are also connected to the bands in the upper region of the crankcase bell.
  • crankcase bell has internal and / or external webs in the region of the connecting points of the ribs.
  • the oil pan flange has a width that is 0.4 times to 0.6 times, preferably 0.5 times, the cylinder bore dimension.
  • the internal combustion engine according to Figure 1 has a block 1, which is composed essentially of a crankcase bell 2 and a cylinder section 3. Bearing arrangements for receiving a crankshaft are fastened in the crankcase bell 2 and are connected to a piston per cylinder unit via a connecting rod. The piston is movable in the cylinder 4.
  • Each bearing arrangement consists of a bearing base body 5 which, together with a bearing cover 7 connected to the bearing base body 5 by screws 6, has a recess 8 for receiving the crankshaft.
  • the bearing base body 5 is connected to the block 1 via two bands 9a and 9b.
  • the straps 9a, 9b extend in the axial extension of the screws 6. Furthermore, the straps 9a, 9b are stiffened towards the block 1 by stiffeners which are designed as cross girders 10.
  • the crossbeams 10 extend from the connection area of the belts 9a, 9b with the bearing base body 5 to the opposite crankcase wall 11 running between the belts 9a, 9b.
  • ribs 12 are also provided, which are approximately in the center of the recess 8 on both sides of the bearing base body and Crankcase bell 2 are connected, so that there is an at least approximately straight connection plane.
  • Further ribs 12a extend from the bearing base 5 to an oil pan flange 13.
  • a further pair of ribs 12b is provided in FIG. 2, which are connected to the belts 9a, 9b and the crankcase bell 2.
  • the ribs 12 are wedge-shaped and the oil pan flange 13 is made narrower.
  • internal and external webs 14a, 14b are connected to the crankcase bell in the region of the connecting points of the ribs 12.
  • the stiffeners are connected in a central area between the bearing base body 5 and the crankcase wall 11 on the belts 9a, 9b and on the crankcase wall 11 connecting the belts 9a, 9b.
  • the ribs 12a extend from the bearing base body 5 to an inwardly widened oil pan flange 13. According to the invention, any combination of the features described in the individual figures is possible beyond the embodiments shown.
