I have a feeling that the Eland sheet does all that malarkey and shows it in the output cells along with the % of variance from perfection.Popshot
thanks for the offer , in the picture it is w/b 31" track 31" [ well as near as I can get ! ]
I was hoping to nudge DannyC to make a spreadsheet [ he really likes that ]
Around 28 degrees with a 134" circlei.e if I established that the inner wheel could turn through 45' without hitting me what would be the angle needed by the outer wheel ?
Simple answer is I don't know , however building it knowing I have lost half the steering to the control mechanism would seem a little short sighted ?Do you really need all that amount of wheel turn? 16 inchers may give the extra clearance.
I would probably choose a pair of steering u/j's , only lighter than your Prius ones !A uj operating at such a steep angle is going to be very heavy.
I will work on the mock-up to get rid of the clamps and front piece in the way , then I will have a better idea what space is available.Bevel gears, a steering box or rack and pinnion would be better IMO. You could bring the steering arms high, over the tyres or low under them.
More likely to make getting the feet over them to reach the pedals impossible .Given the physics of pivot points etc, high is the more physically likely though may impact on getting on and off.
The last picture is looking reminiscent of my original Street-Fox cross-boom arrangement, That chap Brad knows a thing or two!So cleaned up the front end to get this :-
first up room for my heels inside the step
Of course the wood dog leg can be replaced by steel following the path of the overlaid stick , still room to get on seat and clearance for the heels.
and does not impeded wheel at maximum turning radius.
So look at making a better kingpin and add some arms and rods for linking wheels/Ackerman etc
Yes I am sure it is the same parts arranged in a different order !The last picture is looking reminiscent of my original Street-Fox cross-boom arrangement, That chap Brad knows a thing or two!
It's a bonus that both springs and elastomers will work with it , I have a selection of springs however not many in pairs.I'd suggest springs over elastomers for that type of suspension. Springs will give potentially more movement (you don't have to allow that extra movement if undesirable) and will also allow preload to be added which will allow some dialling out of both sag and roll. Springs will allow the best rate to be more easily found and probably cheaper too.
