Swivel bearing / steering knuckle

Hub carriers on the rear axle and swivel bearing on the front axle are responsible for carrying the wheels and crucial to driving comfort and safety. They act as mounting points for the wheel hub, brake disc, brake caliper and suspension arm. Their design differs depending on the axle concept so as to meet specific vehicle requirements. The components must be capable of bearing high wheel loads and are therefore made from strong, corrosion resistant materials such as forged aluminium or spheroidal cast iron. Their robust design ensures the vehicle’s effectiveness and safety.

Key Features Cast Iron

  1. Connection steering arm
  2. Milling machining
  3. Connection swing arm/suspension arm
  4. Main bearing bore

Features and Machining Requirements

In comparison to aluminium, these materials are more
cost-effective but have a higher specific weight. Cast iron
is resistant to wear and tear and can withstand high loads.

  • Forged aluminium or spheroidal cast iron
  • High demand on quality as component is safety-relevant
  • High quantities
  • Close position tolerances
  • High process reliability and dimensional accuracy
  • High abrasiveness
  • More difficult tool accessibility depending on clamping fixture and number of process steps
  • Reduction of cutting forces due to positive cutting edge geometry
  • Adapted cutting data
  • Controlled chip breaking

1. Connection steering arm
