Furukawa’s SMA NT spring has been introduced into their new AUTOTRONIC continuously variable transmission (CVT).
Our SMA NT spring can be used as a combined sensor and actuator. A typical solution is to use the SMA NT spring in a valve system, where it automatically senses temperature change and exerts a significant (calculated) force to actuate the valve. In the case of the A-Class transmission, the valve system automatically changes the direction of oil flow. |
