Despite the fact that CVTs change this ratio with out employing a set of planetary gears, they are still described as acquiring minimal and high "gears" to the sake of convention.
The V-shaped cross-portion from the belt brings about it to trip bigger on a person pulley and decrease on the other; thus, the gear ratio is altered by relocating The 2 sheaves of one pulley closer jointly and The 2 sheaves of another pulley farther apart.[three]
