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 Aluminium

  1. Thrust strut, camber strut and tension strut
  2. Main bearing bore
  3. Pre-machining of main bearing bores

Features and Machining Requirements

O alumínio, com sua combinação de resistência máxima e maleabilidade muito alta, é o material ideal para componentes críticos de segurança que também precisam ser leves. Estas propriedades fazem dele a escolha perfeita para massas sem suspensão.

  • Alumínio forjado ou ferro fundido esferoidal
  • Elevados padrões de qualidade, como componente relevante para a segurança
  • Alta quantidade de peças
  • Tolerâncias de posição estreitas
  • Elevada confiabilidade do processo e precisão dimensional

  • Cortes longos devido à liga forjada/tratada termicamente
  • Acesso difícil à ferramenta, dependendo do dispositivo de fixação e do número de passos do processo
  • Usinagem em uma fixação
  • Usinagem multifuso ou máquinas especiais

Características principais do ferro fundido

  1. Conexão da barra de direção / braço de direção
  2. Usinagens por fresamento
  3. Conexão de oscilador/braço de controle transversal
  4. Furo principal do rolamento

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
