To put it differently, torque ratios are attained once the v-belt rotates in the lower cross part from the enter pulleys and on the increased cross segment with the output pulley.
An additional disadvantage of CVTs is they is usually noisy once the motor is under heavy load. It's because the transmission is constantly altering the pulleys and belt to help keep the engine in its best ability array, which can result in a whining or droning seem.
