Transcript of Torque converter
A torque converter is generally a type
of fluid coupling capable of producing
torque.
Replacement of clutch for automatic
transmission vehicle.
Impeller-Connected to the flywheel and
towards the gearbox
Turbine-Facing the impeller and the main
shaft of the gear box is taken from the
turbine through the impeller.
Stator-Between the impeller and turbine

Stall-The prime mover is applying power to
the impeller but the turbine cannot rotate.
Acceleration- The load is accelerating but
there still is a relatively large difference
between impeller and turbine speed. Under
this condition, the converter will produce
torque multiplication
Coupling- The torque converter is behaving
in a manner similar to a simple fluid
coupling.
Overheating-Continuous high levels of slippage resulting in
damage to the seals that retain fluid inside the converter.
Stator clutch seizure- The inner and outer elements of the one
way stator clutch become permanently locked together,
thus preventing the stator from rotating during the coupling
phase.
Stator clutch breakage- A very abrupt application of power can cause shock loading of the stator clutch, resulting in
breakage.
Blade deformation and fragmentation- If subjected to abrupt
loading or excessive heating of the converter, pump and/or
turbine blades may be deformed.
Balloning-Operating a torque converter at very high
RPM may cause the shape of the converter's housing to be
physically distorted due to internal pressure.
