The development of light metal vehicle frame components is described by means of cast nodes. These nodes are the joining elements for the space frame sections and usually they have no additional functions. The need of saving weight and assembling effort leads to components which integrate additional functions in the joining elements. Wheel suspension mounts or energy absorbing elements are examples for additional functions in joining element. In this paper the prototype manufacturing methods of frames with casted nodes are discussed by means of various vehicle research projects at LKR. The integration of more functions in the components leads to the reduction of the number of parts in a system and to less tolerance adjustment for assembly. "Multifunctional castings" are clearly identified as a future trend in vehicle design.
