The document discusses the design of a centre locking wheel hub and nut system for a Formula Student vehicle. Key points include: - The design aims to increase performance and allow for quicker wheel changes while fitting the specified wheel and meeting load requirements. - Initial ideas included a large or small centre locking nut. Finite element analysis was used to optimize the design and reduce stresses. - The final design utilizes a 6-arm hub geometry for the front and rear hubs, with different brake bobbin mounting for the front. It features a milled drive stud, centre locking thread, and tapered roller bearings. - The centre locking nut was designed to keep the upright and bearings in place while also
