Definitions

  • the invention relates to a method for producing a cylinder liner for Use in the cylinder bore of an engine block by thermal spraying of Spray material on a mandrel serving as a shaped body according to the preamble of claim 1, and the cylinder liner that can be produced by this method.
  • the engine block of internal combustion engines usually consists of one Cast iron or aluminum alloy.
  • cylinder liners are cast.
  • These cylinder liners can be made in different ways.
  • cylinder liners From the FR-A-2413553 or FR-A-1043913 are cast cylinder liners known. Such cylinder liners are made in permanent mold casting. The Cylinder liners are referred to as wet cylinder liners and are pressed into prefabricated engine blocks. The cylinder liners are not suitable for pouring, since between the outer peripheral surface of the cylinder liner and the engine block must remain an annular gap in which the coolant of the Motors extends.
  • From DE PS 12 82 243 is a method for producing aluminum cylinders with cast steel liners. First, by thermal Spraying creates a steel tube, which is then a separate body in the metal block is inserted. To connect the liner with the cast material creates a negative pressure in the liner so that the molten aluminum in the Pores of the steel pipe penetrates. To this complex connection technology too simplify, cylinder liners have already been formed from several layers.
  • the layer forming the tread consists of a wear-resistant and fire-proof material.
  • the liquid engine block material combines with the cover layer.
  • DE 196 05946 C1 discloses such a generic cylinder liner and a manufacturing method of the cylinder liner. It has been shown that complex engine block geometries can cause stresses in the cooled casting during solidification in connection with the shrinkage of the casting material. This leads to considerable warpage in the area of the liner. Since the cylinder liners often still have to be mechanically reworked after casting, it can lead to the wall thicknesses of the cylinder liners being partially reduced. In engine operation, these areas then represent critical zones with regard to thermal, mechanical stability.
  • the invention has for its object to improve a generic method for producing a cylinder liner in such a way that the distortions occurring during casting or in engine operation are prevented. This object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are documented in the subclaims.
  • Cylinder liners according to the invention can be made particularly thin-walled by the provided on the outer peripheral surface of the socket Material accumulation becomes the strength of the bushing effectively reinforced that no warpage occurs after pouring the cylinder block material.
  • the material accumulation in the form of ribs is in the local arrangement as well as in the Number of ribs specifically adjustable for each application. Preferably should at least three circumferential points a material accumulation can be arranged. It can by controlling the spraying process, different cross-sectional shapes of the Material accumulation are generated. In addition to rounds, square ones can also be used Cross-sectional shapes are used. With the profile bars it is an advantage if profiles with high bending and / or torsional resistance are used.
  • the cylinder liner 1 shown in FIG. 1 is produced by a thermal spraying process.
  • the spray materials made of metal and / or metal ceramics which are commercially available can be used as spray materials.
  • the cylinder liner 1 has a cylinder wall 2 over the circumference (FIG. 2), which has partially different wall thicknesses over the circumference, so that wall thickness reinforcements 3, 3 ', 3 ", 3""are formed.
  • the wall thickness reinforcements 3, 3' are preferably designed as ribs and extend over the axial length of the cylinder liner 1.
  • FIG. 2 shows an embodiment variant in which the ribs are connected in one piece to the cylinder wall 2. This embodiment can be produced easily and inexpensively by varying the spray parameters. It would also be conceivable, as shown in Figure 3, to form the rib by separate profile bars 4, 5, 6, which, for. B. welded onto the cylinder wall 2. Different cross-sectional shapes can be used for. B. triangular 5 or rectangular 4, 6 profile bars.
  • the profile bars can additionally be overmolded, so that the ribs have an embedded core.
  • Figures 4 and 5 disclose further alternative embodiments of the invention.
