Definitions

  • the invention relates to a cylinder block made of a light metal alloy for a piston engine at least one cylinder liner.
  • crankcase It is therefore endeavored for the crankcase to be inexpensive, easy to cast and editable
  • these light metal alloys cause problems with the high combustion pressures resulting from the high compression of modern piston engines, especially for diesel engines with direct injection, which these light metal alloys do not have grown.
  • This known embodiment of a cylinder block is suitable for a diesel engine
  • direct injection and correspondingly high combustion pressures are used not to be regarded as a lightweight component, since a large part of the weight is on or off the Cylinder liners, the crankshaft bearing mount and the base formed from the base Gray cast iron is not required.
  • the basic block is made of alloys other than Gray cast iron can exist if only the rigidity of the material of the base block is greater than that of the Cylinder block is, however, no information is given as to which materials are suitable and these Materials should cover the entire basic block, i.e. H. both as cylinder liners and as Be suitable for crankshaft bearings.
  • the invention is based on the problem of creating a cylinder block for a piston engine, which withstands the high demands of modern engines with the lowest possible weight and where it is possible to choose the most suitable materials for the cylinder liners, for the force-conducting elements and for the cylinder block, without regard to the to compromise the required properties.
  • a cylinder block made of a light metal alloy for one Piston engine with at least one cylinder liner proposed, according to the invention cast in, from the crankshaft bearing blocks to the bearing surface of a cylinder head Storage chairs made of a higher heat and fatigue strength than the cylinder block alloy and a low thermal expansion coefficient light alloy, which the Pick up cylinder head and crankshaft bearing bolts or continuous tie rods, to provide.
  • the invention is based on the consideration for the entire cylinder block including the force-absorbing and transmitting areas to provide light metal alloys for the light alloy of the cylinder block forming the water jacket and the crankcase To use inexpensive, easily castable and mechanically machinable light metal alloy. In contrast, a light metal alloy with higher warm and Fatigue strength and a low coefficient of thermal expansion are used, so that in the Let the connection between the crankcase and the cylinder head transmit higher forces continuous flow of power from the crankshaft pedestals to the cylinder head is achieved. The higher heat and fatigue strength of the light metal alloy used serves this goal.
  • the Cylinder liners can consist of the light alloy of the crankcase if the Treads are treated in a known manner to increase wear. It is also possible Prefabricated cylinder liners made of a wear-resistant material, preferably from a insert hypereutectic aluminum-silicon alloy in the cylinder block or with the Pour light alloy of the cylinder block. It is important that the invention Possibility exists for the material of the cylinder block and the camp chairs, respectively, the best select suitable light metal alloys and, if necessary, also one for the cylinder liners use more light metal alloy.
  • crankshaft pedestals to be screwed onto the bearing seats can preferably also made of light alloy with higher heat and fatigue strength as well as a low one Thermal expansion coefficients exist and advantageously in a crankcase lower part the same light alloy as the cylinder block with the bearing blocks Bearing bridges cast in. This creates a power flow from the cylinder head to Crankshaft bearings.
  • a light alloy for the camp chairs and trestles, for the intended purpose is particularly suitable, can have a high silicon and / or a high iron, copper and Have nickel content.
  • the light metal alloy can also be particle or be fiber reinforced.
  • the storage chairs and trestles are prefabricated and made of a special alloy, it is advantageous if they are produced by powder metallurgy by sintering. Through this procedure on the one hand there is the possibility of the storage chairs and trestles each in an appropriate form to press and sinter, whereby the powder metallurgical process gives great freedom in the Composition of the light alloy used. It is also possible to get one Manufacture bolts using powder metallurgy or spray compacting, from which extrusion is used to make a profit from which the camp chairs and trestles can be obtained by separating them with the have the desired thickness produced.
  • the storage chairs and trestles can have openings into which the melt for Pouring used light metal alloy penetrates and when cooling a positive Connection forms.
  • a cylinder block 1 for a multi-cylinder in-line engine shown in FIGS. 1 and 2 is schematic and cut according to the section I-I in the area of a bearing chair 4 and one Cylinder liner 2 shown. From a cylinder liner 2 or two neighboring ones Cylinder liners 2 is in section I - I in the area between parallel legs 14 one U-shaped forked bearing chair 4 reaching wall area shown.
  • two bearing blocks 4 are parallel to one another arranged on both sides of a cylinder liner 2.
  • Storage chairs 4 arranged between the cylinders and at both ends of the cylinder block 1.
  • the storage chairs 4 are cast with a light metal alloy, the crankcase and possibly the Cylinder liners 2 and the water jacket 13 forms.
  • a crankcase lower part 8 is a a plurality of crankshaft bearing blocks 7 are cast in and form in the crankcase lower part 8 Bearing bridges 9.
  • the lower part of the bearing block 4 forms a bore 5 for the crankshaft bearing block 7 Crankshaft bearings.
  • the upper end of the cylinder block 1 forms a support surface 6 for one, not shown Cylinder head
  • In the legs 14 of the bearing blocks 4 are threaded holes 10 for Cylinder head screws and 5 threaded holes 11 for the side of the bearing holes Crankshaft bearing bolts are provided.
  • Crankshaft bearing bolts, not shown, can be through holes 12 in the crankshaft bracket 7 and into the threaded hole 11 screw in.
  • a cylinder block for a multi-cylinder V-engine is shown, which in principle in is constructed in the same way as the cylinder block for an in-line engine according to FIGS. 1 and 2.
  • the crankcase lower part 8 with the crankshaft pedestals 7 and the bearing bridges 9 is the same designed as in Fig. 1 and 2.
  • the cylinder block 15 is designed as a fork block for a V-engine and accordingly has V-shaped forked storage chairs 15, which in turn on each side Are forked in a U-shape with parallel legs 14.
  • a light metal alloy for the bearing blocks 4, 16 and bearing blocks 7, such can be used which have a high silicon and / or a high iron, copper and nickel content, since these Alloys have a high heat and fatigue strength as well as a low one Thermal expansion coefficient result. These properties can be improved if the Light metal alloy is reinforced by adding particles or fibers.
  • a manufacturing process that consists of: Manufacture extrusion bolts by powder metallurgy or by spray compacting and from there Extrusion to produce a profile that matches the cross-section of the pillow blocks and pillow blocks corresponds.
  • the bearing chairs 4, 16 and bearing blocks 7 can be easily removed from this profile Cut off with the required thickness. It is advantageous to use the extruded profile as Manufacture unit of the camp chairs and pillow blocks and the unit from the camp chair and pillow block separate from the extruded profile and only after that the bearing block from the storage chair cut off.
