A symmetrical element 1-step 2-phase torque converter is used with JF506E automatic transmission. The term "1-step" refers to the single turbine and
runner assembly and "2-step" refers to the turbine runner speed relative to the pump impeller speed. When the turbine runner speed is lower than the
pump impeller speed, the mechanism operates as a simple torque converter. When the turbine runner speed is higher than pump impeller speed, the
mechanism acts as a fluid coupling.
The torque converter transmits and multiplies torque. The torque converter is a four-element device:
^
impeller assembly
^
turbine and damper assembly
^
reactor assembly
^
clutch
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.
