Torque Converter

Torque Converter
The torque converter transmits and multiplies torque. The torque converter is a four-element device:
- impeller assembly
- turbine assembly
- reactor assembly
- clutch and damper assembly





The standard torque converter components operate as follows:
- Rotation of the converter housing and impeller set the fluid in motion.
- The turbine reacts to the fluid motion from the impeller, transferring rotation to the geartrain through the input shaft.
The reactor redirects fluid going back into the impeller, allowing for torque multiplication.
The clutch and damper assembly dampens powertrain torsional vibration and provides a direct mechanical connection for improved efficiency.
Power is transmitted from the torque converter to the planetary gearsets and other components through the input shaft.
