alasylösmuunnin

An alasylösmuunnin, often translated as a "frictionless converter" or "slip converter," is a type of torque converter used in some industrial applications, particularly with continuously variable transmissions (CVTs). Unlike a traditional torque converter that relies on hydraulic fluid to transmit torque between an engine and a transmission, an alasylösmuunnin aims to minimize or eliminate energy losses due to fluid friction.

The core principle behind an alasylösmuunnin is to achieve a more direct mechanical connection under certain operating conditions. This can be achieved through various mechanisms, such as the use of a lock-up clutch that engages at higher speeds, effectively bypassing the fluid coupling and creating a direct drive. In some designs, specialized internal geometries or working fluids are employed to reduce churning and shear losses.

The primary advantage of an alasylösmuunnin is its potential for improved fuel efficiency and reduced heat generation compared to conventional hydraulic torque converters, especially in situations where the speed difference between the input and output shafts is minimal. However, these devices can be more complex to design and manufacture, and their efficiency benefits may be more pronounced in specific operating ranges. They are generally found in applications where precise speed control and energy efficiency are critical factors, such as in certain types of agricultural machinery or specialized industrial drives.
