Re: [ST] DN01 Transmission musings

["Baysinger, Jeffrey S (Jeff)" <jbaysinger@xxxxxxxxx>]

I remember seeing something a few years ago about direct-select
transmissions, but the designer was still trying to get support for it,
and trying to get someone to try it. I think he mocked one up in a big
British sports car - Aston Martin or some such - to prove that it worked
and that it could handle a LOT of torque. I didn't know that VeeDub and
Audi got on board, tho it doesn't surprise me a bit.

That's cool, I'm gonna' have to go try one now!

Wasn't the DSG stumbled upon during an effort to create a better
shifting mechanism for bicycles?

Another high-tech transmission in production - VW & Audi call it the
Direct Shift Gearbox (DSG) - was first seen in the 2004 Audi TT and is
now available in the New Beatle TDI.   From http://tinyurl.com/dgd6h :
"... DSG radically shortens shift times by anticipating and preselecting
the next gear. With one gear driving the wheels and another poised to
take over when the computer (or the driver) gives the nod, the act of
shifting becomes a lightning-quick relay race. Two clutches alternately
open and close as one gear after another goes from at-bat to on-deck
status in a scant two-tenths of a second, with no interruption of the
torque flow during full-throttle acceleration."

It's just a matter of time before more of these technologies spin off to
motorcycling.  I for one, welcome them.
