Torque Converter: Description and Operation
Torque Converter
The torque converter transmits and multiplies torque by means of transmission fluid inside the torque converter. The torque converter is composed of
the following:
^
Converter case
^
Pump impeller assembly
^
Turbine assembly
^
Stator assembly/one-way clutch
^
Lock-up clutch
In addition, the use of the lock-up clutch is intended to improve fuel economy as a direct coupling between the engine and the transaxle.
The standard torque converter components operate as follows:
^
Rotation of the converter housing and impeller sets the transmission fluid in motion.
^
The turbine reacts to the transmission fluid motion from the impeller, transferring rotation to the geartrain through the input shaft.
^
The reactor redirects transmission fluid going back into the impeller, providing 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.
