Definitions

  • the invention relates to a cylinder block for a Piston engine.
  • This Arrangement has the disadvantage that it is under pressure Coolant in the contact areas between aluminum and gray cast iron can penetrate, which limit the water jacket. A perfect seal is not possible.
  • the other The disadvantage of this arrangement is that the engine occurring loads from the cast iron Transfer the storage area to the aluminum motor base must be so that there is a change in the flow of force. As a result, the part forming the motor foot very massive with regard to the application of force must be made so that by the use of aluminum existing benefits are only exploited to a small extent can be.
  • the invention is based on the object of a cylinder block cast iron of the type described above to further reduce its weight without this the structural strength is reduced.
  • a cylinder block with the features specified in claim 1 While at a cylinder block, which is made entirely of gray cast iron, for example made of vermiculite, a wall thickness less than 4 mm casting reasons is not possible, therefore no further weight loss by reducing the Wall thicknesses is possible, the invention offers Cylinder block the advantage that by the engine operation still loaded parts made of gray cast iron in the form of a Base blocks including the motor foot are manufactured and that afterwards the application of appropriate core parts of this basic block at least in the area of the liner with a water jacket trained casing made of cast aluminum in a second casting step is provided. This has the Advantage that the power flow between the cylinder head and Motor foot still fully over the gray cast iron runs.
  • the liner and the associated crankshaft bearing mount as well as the motor base are integral made of gray cast iron.
  • the weight loss versus The known motor designs are achieved that the parts forming the casing, primarily the Water jacket that can only withstand the pressure of the cooling medium then also with wall thicknesses between 2 mm and 3 mm but can be made of aluminum, which results in a significant weight reduction.
  • the jacket can also extend over the area of the cylinder block, which in the Area of the crankshaft bearing mount the housing wall forms for the crankcase, so that here too the desired Weight reduction is achieved.
  • Another advantage of the cylinder block according to the invention is that for the liners very much for the friction behavior much cheaper gray cast iron material is available.
  • the basic block at least in the transition area between Liner and crankshaft bearing mount on the outside with at least one extending in the crank axis direction web-shaped elevation and / or groove-shaped depression is provided.
  • This configuration offers the advantage that not only a positive anchoring between the aluminum casing and the gray cast iron base block is created, but beyond it arises a labyrinth-like seal, so that a passage a liquid medium through this area limited space, be it cooling water or oil becomes.
  • the transition area between the liner and crankshaft bearing mounting, the lower one Area of the base block with one that forms the crankcase Housing wall made of cast aluminum is provided.
  • this housing wall integrally is connected to the water jacket.
  • this housing wall in the casting process is made, it is possible on the outside and / or Corresponding ribs to be provided on the inside without significant increase in weight to stiffen the Lead housing wall, so that vibration and / or Roaring symptoms are prevented. It is useful if the housing wall extends into the motor base and embraces it. This creates a positive connection between the motor base belonging to the base block made of gray cast iron and the casing made of aluminum on the other hand reached so that any existing from the cooling process residual stresses resulting from the casting process lead to a lifting of the casing in this area.
  • Fig. 1 is a vertical cross section through a Cylinder block shown for a multi-cylinder in-line engine. The cut is made transversely to the crankshaft axis.
  • the Cylinder block consists essentially of a cast iron, for example vermiculite (GGV) cast basic block 1, the one in the material closure, d. H. also made of gray cast iron, the liners 2 and between two adjacent Liner 2 bar-shaped crankshaft bearing mounts 3, which has web-shaped supports 4 each run into the motor base 5.
  • This basic block 1 is with a casing 6 made of cast aluminum provided on the base block 1 in a second casting process according to the arrangement of appropriate cores is.
  • the casing 6 is the liner 2 in it immediately surrounding area as a water jacket 7 educated.
  • the part of the casing forming the water jacket 7 6 double-walled so that the inner wall 8th the part delimiting the water-carrying cavity 9 the jacket directly to the outer surface of the liner 2 abuts, while the outer wall 10 the cavity delimited to the outside.
  • the casing settles 6 as the housing wall 11, the lower, the Crankcase defining area closes to the outside.
  • the basic block 1 In the transition area 12 between the water jacket 7 and the housing wall 11 is the basic block 1 with a longitudinal arrangement 13 of rib-shaped webs and / or groove-shaped depressions provided when Pour on the casing 6 in this area a positive Connection between basic block 1 and casing 6 form.
  • the housing wall 11 is around the area of the motor base led around the motor foot to the sole area, so that here too the casing 6 is positively connected is.
  • Fig. 2 shows a vertical parallel to Fig. 1 Cross section through the cylinder block, which, like the horizontal section acc.
  • Fig. 3 shows led through the area is in which two liners adjoin each other.
  • elements already described are the same 2, so that on the Description of Fig. 1 can be referenced.
  • the cylinder head 16, indicated only schematically, is over Turnbuckles 17, which are shown here only by their central axis are indicated, clamped directly to the basic block 1.
  • the casing 6 has, as the section shows, in this Area an interruption on either already when casting is taken into account, as shown, or else afterwards when drilling the threaded holes 18 is generated for receiving the clamping screws 17.
  • the area of the transverse openings 14 and 15 is in the Fig. 2 marked by the line III-III horizontal section shown in Fig. 3. 3 is however only the liner 2 and the water jacket 7 in the drawing fully illustrated while the rest Parts of the basic block 3 are only indicated.
  • Fig. 4 shows a vertical longitudinal section accordingly the line IV-IV in Fig. 3 and also only by the area of the liners 2 with the associated water jacket 7.
  • the course of the through the transverse openings 14th and 15 transverse webs formed in the upper area of the liner 2 can also be seen here.
