Definitions

  • the present invention relates to a cylinder crankcase for an internal combustion engine, the base body made of a first material and the cylinder walls made of a second material.
  • the present invention further relates to a method for producing a cylinder crankcase.
  • a reciprocating piston made of an aluminum alloy of an internal combustion engine with an at least partial tread reinforcement to increase wear resistance.
  • the reinforcement can be designed as a synthetic resin-bonded graphite layer with embedded metal particles, a thin glued-on metal foil or an anchored metal plate.
  • a cylinder crankcase for an internal combustion engine which has an easily machinable base body and wear-resistant cylinder running surfaces has and is simple and inexpensive to manufacture.
  • a method for producing such a cylinder crankcase is also to be provided.
  • the first part of the task is solved by providing a grid-like reinforcement between the two materials for the base body and the cylinder walls.
  • these two materials can flow into one another in the area of the reinforcement during the manufacture of the cylinder crankcase, so that the second material for the cylinder walls is ideally anchored in the first material for the base body.
  • the lattice-like reinforcement in the manufacture of the cylinder crankcase prevents the less wear-resistant first material for the base body from penetrating up to the cylinder wear surfaces which are subject to heavy wear.
  • the lattice-like reinforcement consists of a highly thermally conductive material, a very good heat flow between the two materials is also possible in this area, which significantly reduces the thermal load on the cylinder crankcase and ensures a long service life.
  • the lattice-like reinforcement is expediently designed as a wire mesh with a mesh size of approximately 0.1 to 1.0 millimeters.
  • the exact size of the mesh size should be matched to the viscosities of the two materials in the molten state, so that the materials for the basic housing and the cylinder walls can just flow into one another through the meshes of the wire mesh.
  • the lattice-like reinforcement particularly expediently has larger openings on the side facing the base body than on the side facing the cylinder walls.
  • the reinforcement is thus tailored to the preferred case, that the material for the base body in the molten state has a lower viscosity than the material for the cylinder walls.
  • the grid-like reinforcement leaves the web-like areas between adjacent cylinder walls free, so that they web-like Areas consist exclusively of the second material for the cylinder walls.
  • branch channels and / or pouring nozzles are provided for introducing the second material for the cylinder walls.
  • the object is achieved in that the grid-like reinforcement is inserted into a casting mold for the cylinder crankcase during the manufacture of the cylinder crankcase, whereupon the two materials are then introduced into the casting mold.
  • the two materials for the base body and the cylinder walls in the molten state have clearly different viscosities, the first material for the base body in the melted state having a lower viscosity than the second material for the cylinder walls, then the material for the base body should be used first and then that Material for the cylinder walls are introduced into the mold. In this way, even with a particularly highly viscous second material, this material is prevented from being able to reach the area of the base body through the reinforcement, since only the cavities remaining in the casting mold are now filled for the cylinder walls.
  • the two materials can also be introduced into the mold at the same time, provided their viscosities in the molten state do not differ too much from one another.
  • the second material for the cylinder walls is introduced into the mold under increased pressure. This ensures that the wire mesh is not pressed against the wall of the mold, so that the wear resistance of the cylinder walls is not impaired, and that the second material covers the area between the base body or the Filled wire mesh and the mold completely, so that there are no air pockets.
  • FIG. 2 shows a plan view of the cylinder crankcase from FIG. 1.
  • the cylinder crankcase shown has a base body 1 made of an easily machinable first material A and cylinder walls 2 arranged therein made of a particularly low-wear second material B.
  • the first material A is a remelting alloy that has a first viscosity VA in the molten state
  • the second material B is a hypereutectic aluminum alloy that has a second viscosity VB in the molten state, the first viscosity VA being less than the second viscosity V ß .
  • the base body 1 and the cylinder walls 2 or the first material A and the second material B are separated from one another by means of a lattice-like reinforcement 3 made of a closely woven wire mesh.
  • This wire mesh is designed such that it takes into account the different viscosities VA, VB of the two materials A, B by having larger openings on the side of the first material A for the base body 1 than on the side of the second material B for the cylinder walls 2.
  • the wire mesh is shaped in such a way that it leaves the web-like areas 4 between adjacent cylinder walls 2 free and has only one saddle 5 there.
  • the wire mesh consists of a highly thermally conductive material C, such as steel, and the two materials A, B merge into one another in the area of the lattice-like reinforcement 3 without air inclusions.
  • the grid-like reinforcement 3 is first inserted into a casting mold and then the materials A, B for the base body 1 and the cylinder wall gene 2 introduced in the molten state on the respective side of the reinforcement 3 in the mold. It is advantageous if the second material B for the cylinder walls 2 is introduced into the casting mold with a slight time delay and / or with a slightly higher casting pressure in order to achieve a good confluence of the two materials A, B in the area of the reinforcement 3.
  • the introduction of the first material A takes place in the area of the bearing frame walls of the base body 1 and the introduction of the second material B takes place via branch channels and / or pouring nozzles in the area of the crankcase of the base body 1.

Abstract

L'invention concerne un carter de vilebrequin cylindrique pour moteur à combustion interne. Le corps de base (1) consiste en un premier matériau A et les parois cylindriques (2), en un second matériau B. Il est prévu de disposer une armature en treillis (3) entre les deux matériaux A et B. L'invention concerne également un procédé de production dudit carter de vilebrequin cylindrique, selon lequel l'armature en treillis (2) est placée dans un moule en fonte pour ledit carter de vilebrequin cylindrique. Les deux matériaux A et B sont ensuite introduits dans le moule en fonte. Selon l'invention, il est prévu de mettre au point un carter de vilebrequin cylindrique et un procédé permettant de le produire, particulièrement simples et économiques à obtenir.
