What am I missing here?
The friction material and contact surface area of the 1st disc and the flywheel remain the same (or are made smaller) when going to a twin or mutiple disc setup Is the gain from a smaller diameter clutch/pressure plate and more clamping force?? I thought I had read that Porsche is considering twin disc clutches in some of the newer cars, something about being able to upshift while under power?? (IMG:style_emoticons/default/wacko.gif) Hayden or anyone else, care to enlighten us?? (or maybe just me since everyone else might "get-it" (IMG:style_emoticons/default/smile.gif) ) |

Contact for Paul Guard: gears (at) gte (dot-net).
The little blurb I saw recently sounded like Porsche was considering using the same transmission that Audi is putting into some of their cars. The Audi one has two input shafts and two gear stacks, one for even gears and one for odd gears. (It's an auto-manual box.) The controller pre-selects the next gear for you, then when either you tell it to shift or it decides you need to shift, it will disengage the one clutch and engage the other one. Shifts faster than Luhr or Massen or Tazio Nuvolari himself! Note that this is rather different from the multiple-plate clutch setup that we've seen such a good explanation of... --DD (Ugly problem here at work so I'm avoiding it.
