A CVT achieves this infinite gear ratio adaptability by making use of two opposing cone-shaped pulleys with a series or belt that runs concerning them. This setup is very similar to just how a chain operates through the gears of a bicycle.
By the late 1980s, the CVT experienced entered the mainstream owing to Subaru. In fashionable periods, nearly every producer has at the very least a single model with a consistently variable transmission.
