The demand for improved vehicle fuel economy drives the auto engineers to look for opportunities in weight reduction of automotive systems and components. This paper presents inventions on the design and development of a lightweight spindle. In this new product, the spindle body is made from an Al alloy for a substantial weight reduction in comparison to the tradition iron spindle body. The shaft of the spindle is made from high strength steel to meet strength requirements. The design shows the unique feature of the joining area between the spindle body and shaft. The related joining process is applied to produce a strong joint between the two parts made of different materials. The testing results will be presented and discussed.
