Abstract
The arm includes a wheel-side portion for support of a wheel and a body-side portion for connection to the vehicle body, the two arm portions being securely connected to each other by welding. The wheel-side arm portion may be made of cast iron and the body-side arm portion may be made as a steel tubular piece. Alternatively, the wheel-side arm portion is made of cast aluminium and the body-side arm portion is made as an extruded aluminium piece. It is thus possible to combine the high camber stiffness of the wheel-side portion made of cast iron or aluminium with the high compliance in case of impact of the body-side portion made of stamped or extruded steel or aluminium.
