Hi, I'm interested in scooters, and I'm trying to understand CVTs. I know that, as you accelerate, certrifugal force pushes the roller weights outwards, which in turn causes the rear half of the variator to move to the front part. But how exactly does it do this? Why would roller weights moving to the outside of the rear half cause this whole section to move forwards? There are a few sites dedicated to CVTs but none of them explain this part. I'd really appreciate if anyone can offer their viewpoint. I've never seen a real variator, only pictures, which probably doesn't help.
