Definitions

  • the invention relates to an aluminum bronze for the application area of the synchronizer rings.
  • wear resistance is always to be understood as low material removal due to corrosion.
  • Aluminum bronze has compared to other copper alloys e.g. Brass has the advantage that the part weight can be reduced due to the aluminum used. Such alloys are resistant to oxidation due to a protective layer caused by the aluminum. Aluminum bronzes are also highly resilient and wear-resistant sliding materials, their high strength leads to a low wear rate due to the good sliding properties. In addition, aluminum bronzes are easy to weld.
  • the invention proposes an alloy of 7.5-9.5% Al, 7-9.5% Fe, 7-11% Ni, 1.5-4% Si, the rest copper and usual impurities up to a total 1%. All information is given in percent by weight.
  • the alloy a content of 8 - 9% Al, 8 - 9% Fe, 7 - 10% Ni and 3 - 4% Si, the rest copper and usual impurities up to a total of 1% provided.
  • wear resistance values can be achieved, which are significantly higher than those of the brass materials used previously for synchronizer rings.
  • these alloys have a coefficient of friction which is higher than the values customary for these known materials. The invention thus brings a considerable advance over the brass materials previously used in synchronizer rings at approximately comparable costs.
  • a first alloy contains 69.9% Cu, 8.5% Al, 8.2% Fe, 9.4% Ni and 3.5% Si.
  • This alloy has a wear resistance of 1280 km / g and a coefficient of friction of 0.125.
  • the specified wear resistance is defined by the number of kilometers covered until 1 g of material has been removed from the synchronizer ring.
  • the second alloy contains 71.6% Cu, 7.9% Al, 8.5% Fe, 7.4% Ni and 3.5% Si.
  • a wear resistance of 1530 km / g and a coefficient of friction of 0.140 were measured on the synchronizer rings made from this.
  • a third alloy has a content of 71.5% Cu, 8.8% Al, 6.0% Fe, 9.3% Ni, 3.5% Si.
  • a wear resistance of 1320 km / g and a coefficient of friction of 0.115 were determined.
  • silicon is responsible for the formation of the hard wear-resistant intermetallic phases. There should not be any free silicon in the solution, but should be bound by iron and nickel. Iron and nickel also promote the hardening process.
  • the alloys described above were cast at a casting temperature of 1120 to 1180 ° C; This is followed by cooling in air, the cooling rate not being critical. After heating again, hot forming is carried out by extrusion at temperatures of 800 to 900 ° C and cooling again in air. Finally, after re-heating at a temperature of 790 to 890 ° C, the die was drop-forged and the alloy was then cooled in air.
  • the shape of the intermetallic phases is approximately spherical, which is advantageous in terms of the toughness and ductility of the alloy.
