F 550 4WD Super Duty V8-6.4L DSL Turbo (2008)
Torque Converter: Description and Operation
Torque Converter
The torque converter transmits and multiplies torque. The torque converter is a device which includes 4 elements:
^
The impeller assembly
^
The turbine assembly
^
The reactor assembly
^
The 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 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.
