Definitions

  • the invention relates to a method for producing a engine blocks cast from metal with at least one duct arrangement for the lubrication of bearings.
  • crankshaft known for a multi-cylinder machine, each in the range Crank in a crank cheek one closed at both ends Insert the tube into the mold, which is then removed from the metal is enclosed.
  • the required connection channels then to the bearing surfaces on the crankshaft generated by cross holes that go into the interior of the cast pipe.
  • JP-A-59-097 019 it is for the manufacture of an engine block known a straight pipe section as the main channel in the Pour in the cylinder block.
  • the invention is based on the object of a method to create an engine block using a duct assembly is completely poured in.
  • pipe harp can consist of a main channel, which runs through the engine block in the axial direction and branch off from the respective subchannels that to the individual bearing points, for example the crankshaft, to lead.
  • the main channel used in the prior art Straightforward consideration of the necessary mechanical processing must also be of any shape here, the connection end from the engine block with a Predeterminable length can be brought out and thus a much greater freedom to accommodate additional units, such as oil filter, oil pump, or the like. Is given in the engine compartment.
  • a wall thickness of, for example, 2 mm is sufficient for the pipe to be poured in, um in connection with the molding material filling of the pipe system to prevent complete melting during casting. It is advisable to provide sand with a binder, which burns under the heat of the casting process and then by blowing and possibly shot peening can be removed. It is possible for one Main channel to provide an outer diameter of about 10 mm and those that branch off to the individual crankshaft bearing points Subchannels can have an outside diameter of, for example 6 to 8 mm.
  • the pipe system made of mild steel, for example St 12-03 is made and coated with a non-ferrous metal is provided. Copper or comes as the non-ferrous metal Tin or other suitable non-ferrous metals.
  • This non-ferrous metal coating has practically none for the casting process itself Significance but only serves to rust the outer surface to avoid the pipe system.
  • the pipe system consists of parts is composed, with the individual sections their mutual connection points tightly connected are.
  • This tight connection can, for example, by a weld can be made.
  • FIG. 1 The view of a schematically shown in Fig. 1 Engine block 1 cast from gray cast iron for a four-cylinder engine shows the cylinder 2 and between the individual Cylinders 2 lying webs 3, in which the bearings for the crankshaft are attached.
  • Below level 4 on engine block 1 (see FIG. 2) runs in a lateral Projection 5 for the lubrication of the bearing points the crankshaft bearing a main channel 6, from which to branch off two channels 7 from the individual bearing points.
  • the main channel 6 and the branching partial channels 7 are now formed in one piece as a prefabricated pipe system and has the shape of a "pipe harp". How can be seen from the sectional view in FIG.
  • the sub-channels 7 are not rectilinear between the Main channel 6 and the web 3 for the crankshaft bearing, but these are curved, so that the mouth 8 for the bearing point with an intended direction of rotation the crankshaft according to arrow 9 in one open the unloaded part of the warehouse.
  • the sub-channel 7 also runs partially outside the cast material, this part then in the molding material Mold is embedded.
  • the free ends of the pipe system are each as long dimensioned so that they protrude from the finished casting and accordingly for the casting process in corresponding Core marks placed in the mold and held there can be.
  • Simple steel for example that, can be used for the pipes Steel quality St 12-03 can be used.
  • a cast material here comes in particular GG 25, nodular iron GG V40 and the like Material into consideration.
