G'day everyone
One day I hope to be able to contribute to the forum rather than always asking questions but i have one that I’ve been unable to find a decent answer for.
I was looking through a couple of textbooks and over some of our older designs when i noticed that on some of our vehicles the front axle line is forward of the kingpin axis. It would seem to me that this would make the steering unstable, kind of like a shopping cart wheel facing the wrong way. I would have thought that having the axle and kingpin axis intercept or slightly trailing would be better for stability.
Those of you who saw our vehicle during the acceleration event in the 2011 Australian comp will have seen how unstable the vehicle was under brakes and so I wonder if this may have been the cause.
Thanks again for the help
