Wheel Hub/ Spindle Assembly in Billet Aluminum

As you may have seen in my previous drawings elaborating upon my the braking system, I’ve found some great references from which to design from. Everyone knows that Formula 1 is by far the most extreme case for car/technological development in both aerodynamics and composite materials. One of my favour teams to follow is the AT&T Williams formula 1 Team. http://www.attwilliams.com Below are some references as to how they utilize their AP Racing braking system on their 2010 contender, the FW32, effectively cool their Carbon Ceramic Brake Rotors via Flow Tested Brake Ducting. This picture is sourced from http://www.motorsport-total.com.

The image may not be too clear, so I apologize for that. The lower part of the rotor which is emcompassed by the silver material is actually the flow ducting, with the source being the intake to the left. The Rotor is effectively cooled on both sides as well as the caliper assembly. From personal experience, I know that my Wilwoods heated up quite a bit, so I would need a versatile ducting to force air into the entire assembly, rather than just one component like many conventional ducting systems. I would much like to develop a ducting system which goes around the rotor and cools the entire assembly. As I know now, I have a lot of space due to the small offset of my wheels *ROTA P45R specification 18×9.5″ +15 offset* *stock wheels are 15×6.5″ +42*

Yet another reference from my endless internet trolling is a development by a company called MSI. From what I am aware, they specialize in the Subaru and Impreza STI market with their most recent product being a one piece Billet Aluminum Spindle/Wheel assembly. The piece was CNC’d out of a block of T606 *aftermarket industrial standard* aluminum. There are provisions to mount brake calipers, lower control arm ball joints, and a strut/shock assembly. I think the best part of this design is the adjustable bump steer mechanism yet at the same time, I also think it looks rather weak in contrast with the rest of the assembly. Another component of note is how they integrated their brake ducting. These are all cues as to what I need to develop for the future.

^ Bump Steer Adjustment Bracket. Lastly, their Carbon Composite Brake Ducting with a conventional Rotor-only cooling conduit.

I’m pretty sure that this is in my future plans and i’m estimating 4 units of the wheel spindle assembly to cost approximately 3-4 thousand dollars, at 700-1 thousand each. What I would love to develop is a one piece, spindle and strut suspension assembly. One piece assemblies were once utilized in the WRC (World Rally Champions) but unfortunately, I do not have image references. The vehicle was a Ford Escort, back in the early 1990’s. A one piece suspension assembly would be ideal as there are barely any suspension options for the 1995 nissan altima, with the most significant coilover design produced by companies Ksport & D2 Racing. Utilization of industrial standard materials such as *T606 aluminum* is the most economical option but I would like to reinforce the material with kevlar.

Outside of all this 3d-cad work and suspension development, I focused on some immediate tasks and the first was to purchase Adel Clamps. Adel Clamps are utilized in the aerospace industry for the mounting wires & fuel. They are utilized in the automotive industry as well for track cars. The benefits of an Adel clamp vs. say a metal tie is that the Adel has either nylon or rubber insolation. This increases the longetivity of the clamped object, especially if it is of more delicate material such as aluminum. These clamps will be bolted to the floor of my chassis in stock clamp locations and protected by the original plastic guard.

I purchased a total of 16 -8 an clamps for fuel feed lines and an additional 16 for the -6 an for fuel return lines.

My flight leaves in 4 hours. I will upload a lot of engine eye candy when I get back so please stay tuned!

Cheers

    AHFUCKEN-mazing job…i would like to share this wit the KA-T.org community if you dont mind….this is something that is deff needed to be spread about….i stumbled across your website as i was in the process of looking for an OEM spec fullcounterwieghted crank for the ka24de as im looking to spin that motor to 9k (built of course)……
