Based on the speed of the vehicle, the perimeters of every pulley transfer toward or away from one another, switching the travel ratio, turning the chain into grooves involving the pulleys.
When you think about the electric power output curve for that car or truck without having a CVT, you could see this to generally be true. See which the tachometer in this example demonstrates the motor revving up and down with Each and every gear alter, which is recorded to be a spike in the ability output curve (and which the driver feels being a jolt).
