Definitions

  • the invention relates to a cast, thin-walled body, in particular made of cast iron, malleable cast iron and cast iron with spheroidal graphite.
  • a wall thickness of 1 mm is often sufficient for reasons of strength.
  • the walls of such housings should only be oil-tight, while the walls of the wheels should prevent dust from entering.
  • wheels and wheel stars it must be taken into account that only parts of them serve to transmit the forces that arise from the tire to the wheel bearing, while the walls between the supporting parts largely serve only as dirt barriers and are only very weakly loaded in terms of strength.
  • the object of the invention is to propose a thin-walled, cast body which does not have the disadvantages of existing designs.
  • Non-load-bearing thin-walled walls should be castable, and weight reductions of 10% and more should be achievable without a significant loss in strength.
  • FIG. 1 shows a wall 1 with load-bearing extensions 2 of the cross-section of the wall, the individual extensions forming connecting ribs (4, 5) and delimiting a number of filling areas 3, 6.
  • the straight, perpendicular 4 and horizontal 5 ribs shown in the figure can also run in an arc shape.
  • the arch shape is usually preferable if it is a wheel or a round housing.
  • the principle of execution is independent of the geometry of the connecting ribs.
  • the melt flows through the ribs 4, 5, so that the regions delimited by the ribs form filling surfaces 3, 6 of flows from four directions.
  • the flows 7, 8 of the melt are shown schematically.
  • the filling areas 3 are shown as square, rectangular or square, but this is only to be regarded as an example, since they can have any configuration.
  • FIG. 2 A preferred embodiment of the extensions 2 of the wall cross section is shown in FIG. 2, the extensions 2 projecting away from the filling surfaces 3 on both sides.
  • the extensions 2 it is also possible to arrange the extensions 2 only on one side, as shown in FIG. 3.
  • the inner surface of a housing is smooth, which simplifies its cleaning.
  • FIG. 4 shows a further embodiment of the ribs 4, which are curved here.
  • the ribs 4 or 5 preferably have an arcuate cross section so that the cooling of the melt flow is reduced to a minimum.
  • FIG. 5 shows an application example on a wheel star and FIG. 6 shows a section through the wall with the corresponding extensions of the cross section in the horizontal and vertical directions.
  • the described embodiment is therefore only intended for those housings in which no very high pressures occur because the connecting walls are dimensioned relatively thin.
  • the grid transfers the forces exerted on the housing.
  • the weight was at wheel stars and disc wheels savings consistently in the range of 10% of the previous weight.
  • Such analyzes can e.g. be carried out by means of the finite element method with the aid of a computer.
  • the shape and dimensioning of the grids and the filling areas can be optimally calculated. It is important that all forces are transferred from the grille, while the connecting walls mostly only serve as secondary supports or as barriers against liquids, solid substances or gases.
