a competition kart with a single solid rear axle has a different steering setup from the car. the wheels also dig into the ground to lift one of the rear tires up, which allows the cart to actually turn. otherwise they understeer under enough throttle.
when a car goes fast enough you actually want anti-ackermann. the slip angles and not the actual angles are what matter, and the inner wheel
has a different load which means it needs to turn less rather than more in order to still grip.
- giardini 7y agoOur kart had a live rear axle with power to both wheels and slicks on the rear. Top speeds was < 60 mph so standard Ackerman geometry was fine. On a track or flat parking lot you could throw the wheel hard left or right even at max speed with no controllability problem other than the aforementioned slight "washing out" if the surface was slick. It would go into a very nice predictable controlled slide. I miss it! It was great training for later driving a car. I never had the urge to do anything foolish in an automobile b/c the kart was always far, far more exciting. Driving a car was dull in comparison.
- joshu 7y agoshifter karts are faster, but the one i modified for a project only did 60mph. you still needed to lean. you were probably still seeing a great deal of slip. take a look at the steering on a pro kart - the wheels are deeply angled around the kingpin and dig into the ground.
