The design of wheel hubs must be based on stresses generated under customer usage through operational loads acting on the wheel. Therefore, the service loading conditions must be taken into account as well as the generated stresses and the hub fatigue properties. In this paper the decisive parameters for design and durability - operational loads, fatigue properties, which depend on material and manufacturing technology, and design - are discussed and the procedure for an optimum light-weight design is treated. Finally, the test procedure for durability approval, the corresponding test facility, the test programs and requirements, and some typical test results are presented.
