Abstract
An integrally cast aluminum subframe for a vehicle suspension system has increased stiffness for an overall vehicle frame while minimizing the thickness of the main aluminum casting by using tension/compression struts to resist flexing. Various strut attachments are shown that simplify manufacturing and lower the cost. The invention results in further improvement of weight reduction while simultaneously achieving a desired amount of stiffness.
