Hello folks, I am a Mechanical Engg. student(bachelor). I came across a 3-wheeler scooter on the internet which has a unique swirl/tilt mechanism for the safety and improves the dynamism of the vehicle. later after some looking, I found there were several scooters using this kind of mechanism. But I could find the how these mechanisms really work. I am very curious to know what are fundamentals of these designs and how suspensions are mounted and what is fatigue life.
