so been looking into hub centred steering which is very common on feet forward PTW (passenger two wheelers) but not so common on typical upright (non-recumbent) motorcycles. Bob Tait produced a few hub centre mechanism for the voyager feet forwards and having look at photos of those and also designs critiqued by Tony Foale I have had my first go at trying to model one in Sketchup 8.
three things i've learnt to do in attempting this.
1) use the ruby console (not necessary but interesting to me as I do software for a living)
2) draw spheres in sketchup (tip you need to start at about 100mm diameter and scale down the result rather that try to follow the diameter of a circle with another circle of 1mm. Sketchup doesn't like the limits imposed by the small values.
3) repeat draw (tap ctrl key) puts the mode in additive so will naturally copy and paste new entities. for example when drawing the bearings and rotating about a common centre then this is very useful.
Anyway he is my first attempt. Came out pretty good I think.
Used corrugated metal effect to make it look more realistic.
to demonstrate where the internal bearings are.
