However, if we abstract all the complications and qualification and
reduce a tilting suspension to the fishbone of necessity (that's a
pun, don't sweat it), yes, you can imagine what I'm talking about. Try
this:

Imagine the digit 8 made up of four long equal-length laths of wood
and three short equal-length laths of wood, pinned at all joints so
that the thing is a folding mechanism rather than a rigid structure.

Turn your 8 sideways. Now you have three parallel uprights in a row,
and two parallel longer pieces per side connecting the central upright
to each outside upright on that side.

The central upright represents the chassis and the rider, in short the
trike's entire payload.

The two outer uprights represent the wheels.

Two parallel arms from the centre payload to each wheel are the
suspension wishbones, seen from the side.

In a corner the payload will tilt.

On your figure 8, tilt the payload, represented by the central
upright. The wheels tilt, pulled by the links.

Reset to level. Tilt the payload, represented the other way The wheels
tilt, pulled by the links.

That's it, a tilting suspension. All the rest is detail and compromise
to make it work in the real world.

How do you locate the angle of tilt? And where does the energy come
frome to lift the rider back up?
