Front upright and hub design

I have been working on my designs for the front uprights and Hubs recently. Just thought i'd update with a bit more on my work..

I will be using 355mm brembo discs in conjunction with Wilwood W6A calipers. Wheel bearings consist of two, widely spaced, low profile taper roller bearings. The large wheel bearings are pressed in the upright and the hub runs within them, secured in position by a thread and nut against the inner bearing. The hub shaft itself is large in diameter and mostly hollowed out in the middle allowing for a very strong yet light design. The upright itself will be machined from a billet of aircraft grade aluminium whilst the hub will be turned from a billet of EN24T steel.






A large effort of mine has been to make suitable provisions for cooling of the front brakes. As such, the milled-out pockets through the main structure are arranged so that air can pass through the upright to the discs, fed through an air duct bolted to its inside. The lower wishbone mount is fixed but the upper wishbone mount and steering arm mount are both part of a bolt-on piece. This bolt on piece allows me to shim in or out enabling changes in camber without affecting bump-steer at all.









The main aim in this area of my design is to keep things lightweight in order to reduce the unsprung mass. Careful research and calculations have been made to achieve this but still be able to cope with the high peak loadings that a road going car may see in everyday use, e.g. potholes and kerbs.








Now to source the bearings and materials to start manufacturing!..
