A Design Study in Austempered Ductile Iron - Smith Foundry Drive Wheel

Drive Wheel for the Tracks on a Compact Utility Loader

Smith Foundry is producing over 2000 wheels a year for Toro.

The direct benefits of casting the drive wheel in austempered ductile iron in green sand are --
  • Cost Savings -- a 55% reduction in production cost compared to the original assembly design based on part cost savings and reduced assembly cost.
  • Weight Savings -- a 15% weight reduction compared to the original design in steel.
  • Performance Benefits - Superior wear, durability and appearance compared to the assembly design.
