Mancal articulado/suportes de roda

Os suportes de roda no eixo traseiro e os mancais articulados no eixo dianteiro são responsáveis por sustentar as rodas e são cruciais para o conforto e a segurança ao dirigir. Eles servem como pontos de montagem para o cubo da roda, o disco de freio, a pinça do freio e o braço de controle transversal. A sua construção varia de acordo com o conceito de eixo, a fim de satisfazer os requisitos específicos dos veículos. Os componentes devem ser capazes de suportar altas cargas nas rodas e, portanto, são feitos de materiais fortes e resistentes à corrosão, como alumínio forjado ou ferro fundido esferoidal. A sua construção robusta garante o desempenho e a segurança do veículo.

Características e requisitos de usinagem

Aluminium, with its combination of high strength and very high flexibility, is the ideal workpiece material for safety-critical components that also need to be lightweight. These properties make it the perfect choice for unsprung masses.

  • 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

  • Long chipping due to wrought alloy and forged/ heat treated
  • More difficult tool accessibility depending on clamping fixture and number of process steps
  • Machining in a clamping system
  • Multi-spindle machining or custom machines

1. Thrust strut, camber strut and tension strut

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
