Abstract
AISIN AW has developed a new Continuously Variable Transmission (hereafter CVT) with torque converter for small capacity engines. The target vehicles are B class cars. The following items are the concept of the development. - Compact size to be applicable to small cars in Japan (K-car). - The lightest in the world. - Low noise level in addition to improved fuel consumption. The CVT introduces neutral-control logic and a long-travel damper on the torque converter for expansion of the lock-up area.
