In my RC monster truck, ackermann is implemented with bended horns on each wheel, and the steering rods slide from side to side. In this ATV, the rotating platform is the one that "supposedly" implements the ackerman. But riding the ATV, it doesn't turn nicely on full lock (chinese "japanese-wannabe brand"), which prompted my to check to see if the ackerman geometry is right. If it's not, then I'd go to leadscrew on a blink... I checked this morning and I believe it would be easier to do mechanically. Another idea that crossed my mind was to cut the steering axle (as I was going to do one way or another) and install a lever perpendicular (or almost, since there's some rake angle to the steering column) to the steering axle and use it as a lever, but thinking better, levers, pulleys and gears aren't the same thing mechanically in terms that all of them distribute power differently? Is there any advantage of using one over the other?
