Definitions

  • the invention relates to a cylinder block for a piston engine.
  • a cylinder block made of gray cast iron which is structurally designed so that on the one hand there is a weight reduction, on the other hand a high structural strength is ensured, which is achieved in particular by the fact that between the two outer sides of the water jacket Two cylinders each have a reinforcing rib which is U-shaped in cross section and extends into the area of the crankshaft bearing mount, so that the forces which are effective between the cylinder head and the crankshaft bearing and can be absorbed by the cylinder block can be absorbed primarily via these reinforcing ribs, so that all other wall parts can be made noticeably thinner.
  • the object of the invention is to further reduce the weight of a cylinder block made of gray cast iron of the type described above, without reducing the structural strength.
  • a cylinder block for a piston engine with at least one cylinder, which has a base block formed from the liner, the crankshaft bearing mount and the motor base, which is made of gray cast iron in one piece and integrally with material and with a casing formed as a water jacket in the area of the liner Aluminum.
  • the cylinder block according to the invention offers that Advantage that the parts loaded by the engine operation continue to be made of gray cast iron in the form of a basic block and that after the application of appropriate core parts this basic block is provided at least in the area of the liner with a water jacket made of cast aluminum in a second casting step. This has the advantage that the power flow between the cylinder head and the motor base continues to run entirely over the gray cast iron part.
  • the liner and the associated crankshaft bearing mount as well as the motor base are made of gray cast iron in one piece.
  • the reduction in weight compared to the known motor designs is achieved in that the parts forming the casing, first of all the water jacket, which only has to withstand the pressure of the cooling medium, can then also be produced with aluminum with wall thicknesses between 2 mm and 3 mm, whereby there is a significant weight reduction.
  • the jacket can also extend over the area of the cylinder block which forms the housing wall for the crankcase in the area of the crankshaft bearing receptacle, so that the desired weight reduction is also achieved here.
  • 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 part of the casing forming the water jacket is of double-walled design in its water-carrying parts, the part forming the inner wall lying directly against the liner and the part forming the outer wall running at a distance therefrom.
  • This configuration has the advantage that the pressurized cooling medium cannot penetrate into boundary areas between the aluminum casing and the gray cast iron base block, so that sealing problems are avoided from the outset.
  • the pressurized cooling medium is limited only to the area of the inlets and outlets by self-contained walls made of cast aluminum.
  • the base block at least in the transition area between the liner and the crankshaft bearing receptacle, is provided on its outside with at least one web-like elevation and / or groove-shaped depression running in the crank axis direction.
  • This configuration offers the advantage that not only a form-fitting anchoring between the aluminum casing and the gray cast iron base block is created, but also a labyrinth-like seal is created, so that a passage of a liquid medium of the space delimited by this area is cooling water, be it oil, is avoided.
  • the lower area of the base block is provided with a housing wall made of cast aluminum that forms the crankcase. It is expedient if this housing wall is integrally connected to the water jacket.
  • a housing wall shielding the crankshafts from the outside is made of cast aluminum instead of gray cast iron, results in a further possibility for weight reduction, especially since the housing wall itself has no supporting functions. Since, for casting reasons, no smaller wall thickness can be produced from gray cast iron, the "material exchange" according to the invention results in a further significant reduction in weight.
  • this housing wall is produced in the casting process, it is possible to provide corresponding ribs on the outside and / or inside, which stiffen the without significant weight increase Lead housing wall, so that vibration and / or droning phenomena are prevented. It is expedient if the housing wall extends into and engages around the motor foot. This results in a positive connection between the base of the gray cast iron motor base on the one hand and the casing made of aluminum on the other hand, so that any existing stresses resulting from the cooling process of the casting process do not lead to a lifting of the casing in this area.
  • a vertical cross section through a cylinder block for a multi-cylinder in-line engine is shown. The cut is made transversely to the crankshaft axis.
  • the cylinder block essentially consists of a base block 1 cast from gray cast iron, for example vermiculite (GGV), which has the liners 2 and the crankshaft bearing receptacles 3, which are designed in a web-like manner between two adjacent liners 2, in the material connection, ie also from gray cast iron, which have web-shaped supports 4 each run into the motor base 5.
  • This base block 1 is provided with a casing 6 made of cast aluminum, which is on the base block 1 in a second casting process is poured on according to the arrangement of appropriate cores.
  • the casing 6 is formed as a water jacket 7 in its area immediately surrounding the liner 2.
  • the part of the casing 6 forming the water jacket 7 is double-walled, so that the inner wall 8 of the part of the casing delimiting the water-carrying cavity 9 lies directly against the outer surface of the liner 2, while the outer wall 10 delimits the cavity from the outside.
  • the casing 6 continues as a housing wall 11, which closes off the lower region that defines the crankcase.
  • the base block 1 is provided with a longitudinal arrangement 13 of rib-shaped webs and / or groove-shaped depressions, which form a positive connection between base block 1 and jacket 6 when the jacket 6 is poured on in this area.
  • the housing wall 11 is guided around the motor foot into the sole area, so that the casing 6 is also connected in a form-fitting manner here.
  • Fig. 2 shows a parallel to Fig. 1 performed vertical cross section through the cylinder block, which, like the horizontal section acc. Fig. 3 shows, is led through the area in which two liners adjoin each other.
  • the elements already described in FIG. 1 are identified by the same reference symbols in FIG. 2, so that reference can be made to the description of FIG. 1.
  • the narrow connection area of the base block between two immediately adjacent liners in the illustrated embodiment by two narrow, slit-shaped Opened transverse openings 14 and 15 which are associated with the upper region of the liner forming the cylinder.
  • the aluminum material flows through the slot-shaped transverse openings 14, 15, so that the mutually facing inner walls 8 are integrally connected to one another in this area and thus also fixed to the base block 1.
  • the further advantage of this arrangement is that, due to the better thermal conductivity of the aluminum material, a better heat dissipation into the water jacket 7 is effected from this area, which is adjacent to the combustion chamber of the cylinder formed by the liner 2, via the transverse webs made of aluminum.
  • the cylinder head 16 which is only indicated schematically, is clamped directly to the base block 1 by means of clamping screws 17, which are only indicated here by their central axis.
  • the sheath 6, as the section shows, has an interruption in this area, which is either already taken into account in the casting, as shown, or which is subsequently generated when the threaded holes 18 are drilled to receive the tensioning screws 17.
  • transverse openings 14 and 15 The area of the transverse openings 14 and 15 is shown in FIG. 3 in the horizontal section identified by the line III-III in FIG. In Fig. 3, however, only the liner 2 and the water jacket 7 is shown fully in the drawing, while the remaining parts of the base block 3 are only indicated.
  • Fig. 4 shows a vertical longitudinal section along the line IV-IV in Fig. 3 and also only through the area of the liners 2 with the associated water jacket 7. The course of the transverse webs formed by the transverse openings 14 and 15 in the upper region of the liner 2 can also be seen here.
