How does the rear clutch work on a CVT?

What does the Belt Line on a CVT mean?
5) This line represents the tallest ratio the CVT can provide, or high gear. The belt is all the way OUT on the front clutch, and all the way IN on the rear clutch. 6) Maximum power as measured on a chassis dyno occurs somewhere in the middle of the CVT’s range.
Why do CVT belts fail in low range?
Belt temp testing proves there is a huge difference in belt temps when using low range versus high range and less slippage. One in low range you are letting the belt ride higher on the primary and it has more grip there and two the engine is turning more rpm which makes air flow better through the clutch fan and cover.
Where are the brake shoes in a CVT?
Inside of the rear clutch are three brake shoes that are held in place with extension springs. Once sufficient rpm is achieved centrifugal force starts to move the shoes in the rear clutch outward against spring tension of the three little extension springs.
As the rpms rise, the rollers in the front variator are flung outward in their slots and have the effect of squeezing the front sheaves together, thus gripping the belt and starting it to move. As the belt moves it begins to rotate the rear clutch.
What happens if the CVT belt breaks on a UTV?
