Definitions
- the invention relates to a method according to the preamble of claim 1 for the production of a cylinder crankcase with a plurality of cylinder liners.
- the invention further relates to a cylinder liner according to the preamble of claim 8 with a material strip fixed thereto.
- cylinder crankcases of internal combustion engines For the production of cylinder crankcases of internal combustion engines, it is a common method to pour cylinder liners in the cylinder crankcase, which consist of a particularly resistant material and have suitable tribological properties. These cylinder liners usually extend over the entire length of the cylinder bore.
- DE 101 53 720 C2 shows a cylinder crankcase with short cylinder liners which essentially lie between the upper and the lower one
- Cylinder liner can tilt during the guided by the slider movement. Since the cylinder liner is a rigid body, it may damage the mold. Of Further, the cylinder liner does not completely cover the quill, resulting in contact between the hot casting material and the quill during the casting process. This leads to increased wear of the quill.
- DE 102 38 873 B4 shows a cylinder liner for a cylinder crankcase, which has a contouring on its crankshaft-side end face.
- the cylinder liner is held on a quill and is supported by the contoured end face on the quill.
- the closed, non-contoured portion of the surface of the cylinder liner extends between the cylinder head end of the cylinder liner and the bottom dead center of the lowermost piston ring during piston movement.
- the positioned on a Quill cylinder liner is supported on its contoured face only at the highest elevations of the contour of the quill.
- the sleeve is also unprotected against contact with the Umgußmaterial.
- JP 06 185 401 A shows a cylinder crankcase with a short liner.
- the axial extent of the bushing is dimensioned so that it extends only over the length of the piston rings when the piston is in the top dead center of its movement.
- DE 101 53 721 B4 shows a casting tool for producing a cylinder crankcase, wherein a cylinder liner is cast into the cylinder crankcase.
- the cylinder liner does not extend the full length of the cylinder bore but is spaced at its cylinder head end by a spacer ring to an upper wall of the mold during the manufacturing process.
- the cylinder liner is at her Cylinder head side end of the casting material clasped and held.
- the disadvantage here is that the positioning of the spacer must be done with great precision to comply with predetermined tolerances, and that the spacer must be removed in a subsequent operation again.
- EP 0 871 791 B1 describes a method for the production of thin-walled tubes from a spray-compacted AISi alloy, which is particularly suitable for the production of cylinder liners, since the manufactured tubes have the required cylinder liners properties in terms of wear resistance, high temperature resistance and reduction of pollutant emissions.
- EP 0 858 517 B1 describes a process for the production of liners from a hypereutectic AISi alloy by spray compacting.
- EP 0 848 760 B1 describes a further process for producing cylinder liners from a spray-compacted, hypereutectic AISi alloy.
- DE 102 25 657 B4 describes a mold assembly for the production of cast aluminum engine blocks comprising a plurality of cylinder liners.
- the mold assembly is composed of a plurality of casting cores, wherein in particular for a positioning of the cylinder liners, a cylinder jacket core is used with a plurality of cylinder jackets, which cylinder jackets along their axial extent each have a taper of its outer diameter.
- the cylinder liners each have a tapering of the outer diameter adapted tapering of its inner diameter, which is greater by a multiple than the wall thickness of the cylinder liners. It is the object of the invention to provide a method according to the preamble of claim 1 and a bushing according to the preamble of claim 8, wherein the cylinder liners can be particularly easily positioned and used just as easily as conventional long cylinder liners.
- An inventive method for producing a cylinder crankcase with a plurality of cylinder liners comprising the steps of providing at least two cylinder liners each having a first cylinder head end and a second crankshaft end and a liner body, setting the cylinder liners in a mold and casting around the cylinder liners with a casting material is characterized characterized in that on each liner body, a strip of material is defined, which projects axially at least the second, crankshaft-side end of the cylinder liner.
- the design of the liner body of the cylinder liner becomes one in comparison with a conventional one
- Cylinder liner allows shorter axial extent in a simple manner.
- the cylinder liner formed in common from the liner body and the material strip has approximately the same length as a conventional cylinder liner.
- the relatively thin strip of material is melted during the casting and thus forms advantageous in the solidified Cylinder crankcase with the Umgußmaterial a common part.
- the compared to conventional cylinder liners shortened liner body leads to a reduction in the cost of the cylinder liner, since the liner body due to the thermal and mechanical demands on the cylinder surface must be made of a high quality and expensive material during the not belonging to the cylinder surface material strip can be made of a simpler material.
- the setting of the cylinder liner in the mold takes place in that the material strip is attached to a part of the mold.
- this part of the casting mold is a sleeve which has the same shape as in the known methods for conventional cylinder liners.
- the plugged cylinder liner circumferentially surrounds the sleeve.
- the attachment can result in a particularly simple placement of the liner, since this process is not significantly different from placing a conventional liner
- Cylinder liner is different.
- the material strip of the plugged cylinder liner thereby protects the part of the mold, which is not covered by the liner body, from contact with the casting material, thereby increasing the life of the casting mold.
- the axial extent of the shortened liner body substantially corresponds to the length of the piston stroke within the cylinder crankcase.
- the cylinder liner is arranged in the cylinder crankcase, that the liner body is limited in its axial extent substantially to the travel of the piston skirt.
- the cylinder liner is placed so that the cylinder head side end of the liner body is positioned at the level of the cylinder head gasket.
- the one in the Cylinder crankcase cast, shortened compared to a conventional Zylinerlaufbuchse liner body is advantageously enclosed on its crankshaft side end face of the cylinder crankcase forming casting material.
- the common length of the liner body and of the material strip of each cylinder liner substantially corresponds to the length of the respective cylinder bore.
- the strip of material associated with the trim is preferably removed from the cylinder bore.
- the method used for this purpose in the final machining is preferably a honing or boring of the cylinder bore or another, for example chip-forming machining of the cylinder surface such as internal turning.
- the cylinder liners are arranged in the mold in such a way that the liners are at least partially in contact with each other. It is preferably provided that the liner body are flattened on its outer side along the contact surface.
- the cylinder liners are in particular arranged so that the material strips fixed to the liner body are not in contact with each other. The material strips, the crankshaft side of the liner body of the Cylinder liners protrude, thus can be well flowed around by the casting material or Umgußmaterial.
- Stem body is fixed, which projects axially on at least one end face of the liner body.
- the strip of material covers the inside of the liner body at least partially.
- the strip of material can then be attached to the liner body in a particularly simple manner by frictional connection, for example gluing, by positive engagement, for example by mechanical clamping, or by a combination of force and positive engagement.
- the material strip is circumferentially fixed to the inside of the liner body.
- the strip of material surrounds the outside of the liner body circumferentially.

- the outer diameter of the cylinder formed by the material strip and the inner diameter of the cylindrical liner body are preferably the same or aligned, so that the strip of material in the liner body has a tight fit.
- the cylindrical strip of material covers a partial surface of the inner side of the bushing and protrudes on an end face of the liner body in the axial direction from the liner body.
- the cylindrically curved strip of material covers the entire inner surface of the liner body.
- Such a configuration allows a particularly uniform and smooth configuration of the inner surface of the cylinder liner.
- the cylinder liner of the liner body has a recess which is formed for receiving the strip of material.

- the depth of the recess and the thickness of the material strip are at most equal to the thickness of the material removed in a finishing step of the inner surface of a cylinder crankcase.
- the liner body consists of a spray-compacted material, which is in particular light metal or a light metal alloy.
- a spray-compacted material which is in particular light metal or a light metal alloy.
- materials from the group consisting of aluminum, magnesium, aluminum-silicon alloys, aluminum-base alloys and magnesium-based alloys have been found to be suitable materials for the liner body and the process of spray compacting to be a manufacturing process for liner bodies particularly suitable.
- the strip of material also consists of light metal or a light metal alloy, wherein the strip of material may in particular be an aluminum sheet.
- Such strips of aluminum sheet metal are simple and inexpensive to manufacture and well suited to their material properties such as the flexibility or the melting temperature.
