Schwenklager / Radträger

Radträger an der Hinterachse und Schwenklager an der Vorderachse sind verantwortlich für das Tragen der Räder und entscheidend für Fahrkomfort und Sicherheit. Sie dienen als Aufnahmepunkte für Radnabe, Bremsscheibe, Bremssattel und Querlenker. Ihre Konstruktion variiert je nach Achskonzept, um spezifischen Fahrzeuganforderungen gerecht zu werden. Die Komponenten müssen hohe Radlasten tragen können und sind daher aus festen, korrosionsbeständigen Materialien wie geschmiedetem Aluminium oder Sphäroguss gefertigt. Ihre robuste Bauweise sichert die Leistungsfähigkeit und Sicherheit des Fahrzeugs.

Merkmale und Zerspanungsanforderungen

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

1. Combination Tool

Fine machining of close diameter tolerances with long projection length
High shape accuracy due to precisely ground blades

1. Drilling from solid

Cost-effective drilling from solid using QTD indexable cutting edge

2. Fine boring + bearing seat machining

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
