A long time ago there was an example of another kind of active tilt (this QSR
one uses gravity, near as I can tell) posted by, IIRC, Eric Brok.

That one used 45 degree sloped pivots to force turns as the cars went through
curves. VERY clever design and obviates the need for gearing...

Hope that helps! Tilt trains are cool. I have spotlighted the original QSR post
and hope others do too.
