The stator assembly is mounted on a stationary shaft which is an integral part of the oil pump. The stator (1) is located between the impeller (2) and the
turbine (4) within the torque converter case.
The stator contains an one-way clutch (1-4), which allows the stator to rotate only in a clockwise direction. When the stator is locked against the
over-running clutch, the torque multiplication feature of the torque converter is operational.
Torque Converter Solenoid
In order to reduce heat build-up in the transmission and buffer the powertrain against torsional vibrations, the TCM can duty cycle the Torque Converter
Solenoid to achieve a smooth application of the torque converter clutch. This function can occur at various times depending on the following variables:
-
Shift lever position
-
Current gear range
-
Transmission fluid temperature
-
Engine coolant temperature
-
Input speed
-
Throttle angle
-
Engine speed
Operation
OPERATION
The torque converter transmits engine torque to the transmission. When it is not locked up, it transmits the torque by means of oil. When it is locked up,
it transmits the torque by means of the lockup piston.
The lockup damper is designed to soften the impact as the torque converter locks up.
The torque converter is a 3-element, single-stage, 2-phase type.
The term single-stage indicates that there is 1 turbine runner (output element). The term 2-phase indicates that the mechanism works as a torque
converter when the turbine runner is turning slowly relative to the pump impeller and as a fluid coupling when the turbine runner is turning quickly
relative to the pump impeller.
