The upright assembly is a key structural element in the wheel assembly of any car, especially in high performance vehicles in which the suspension assembly has a lot of distinct elements. Differently from common passenger cars, in this study the main goal is focused on lowering the weight and maximise the stiffness of the components. Doing so it is possible to increase the overall performances of the vehicle both in terms of longitudinal and lateral accelerations. This study has been carried out on a Formula Student prototype, a 4-Wheel-Drive (4WD) fully electric racing vehicle. In particular the vehicle on which the assembly has been designed is the one of Squadra Corse PoliTO, the racing Team of Politecnico di Torino, in which I had the opportunity to work as a Mechanical Designer in the Unsprung Masses division in the first year and as Team Leader in the second year of my experience.
