Driveshaft in relation to the general layout

[marcush.]

With the very limited amount of suspension travel on current F1 cars, I don't understand why they bother with CV joints at all. I design rotorcraft drivetrains and we use flex couplings to deal with angular mis-alignment/shaft flexing. No moving parts, splines or lubrication issues to deal with, and they are light and reliable.

You know ,formula 1 is not a very innovative field ,it´s a very conservative environment really .Newey is interested in Aero so maybe he takes driveshafts as a given ...On the other hand ..metalore as one of Formula 1 s driveshaft/couplings supplies is also heavily invoved in aerospace,so they should know?

CTG does supply CF driveplates as substitute for Hardy Driveshaft couplings for years to the motorsport ,but those can only cope with minor misalignments as i understand.

I doubt rotorcraft are seeing anything like the shock loading an F1 shaft sees when the wheel clatters over a kerb at full throttle.
Also, the rear of an F1 car has a fair amount of travel, more than many people seem to think.
