New Carbon Swing Arm

Robert Linton · 05-25-2002, 07:45 PM

Although I know I am taking my life in my hands by posting additional pictures, for those of you who are interested attached are five graphic representations of the rear corner for a Type 964 that will exist by July, The salient points:

1. carbon fiber swing arm;
2. bonded titanium monoball;
3. bonded titanium carrier;
4. titanium spring plate with titanium rod end;
5. wheel bearing with ceramic balls;
6. carbon fiber cooling ducts for wheel bearing, outboard CV and brakes;
7. 300M outboard CV with ceramic balls and integrated center screw for Porsche centerlock system;
8. titanium hub with integrated titanium driving pegs;
9. titanium aluminum 3-way adjustable dampers;
10. titanium dual springs with composite transition piece;
11. 4130 anti roll bar with 4-way adjustable 4130 machined ends;
12. adjustable titanium drop link;
13. 4 piston lithium aluminum caliper with titanium pistons, air gaps and bleed quick disconnect valve;
14. carbon ceramic brake disk with floating aluminum bell with titanium bobbin attaching system.

As to weight savings, this should be well over 40 pounds per corner and performance should be considerably increased even beyond that attributable to reduction in unsprung and, with respect to certain components, rotating weight.

Finally, as I have said in other posts, this is not being done simply for one vehicle or for amusement or to spend money and I am only posting because some of my fellow Rennlisters are interested.

Bob-Spectacular CAD drawings, should be beautiful bits when done both intellectually and physically. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

Robert,

Amazing. But I gotta ask....you mention that you are not doing this for one vehicle, to spend money, or for amusement...then why are you doing this? <img src="confused.gif" border="0">

Mike:

To demonstrate to three specific audiences – semi and professional racers and certain manufacturer personnel -- what can be done for dramatic improvements to sportscar racing, both in terms of rapid high end design and in terms of being able to rapidly and efficiently manufacture small numbers of specialty items (as, for example, would be required under ACO homologation rules).

It's probably just me, but my Netscape browser wouldn't display the pictures, however Internet Explorer displayed them just fine. FYI in case anyone else is wondering why they can't see what others are commenting on.

Robert,

As always, I cannot wait to see the photos of the actual goods. Please post them after production.

Once again, I am sincerely impressed.

Looking forward to your latest work,

Marc
