Torque Converter
INTRODUCTION
.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
Parts of a Torque converter
To transmit increased or decreased power
from one shaft to another. A variable
torque is impressed on the driven
Member without the use of gear train or
clutch.
TORQUE CONVERTER:-
Function:-
Torque Converter
Automatic transmissions use a torque converter to couple the engine
to the transmission.
• The torque converter:
- Transmits the twisting force or torque delivered to it by the engine
crankshaft
- Multiplies engine torque when additional power is needed
The amount of torque transferred from the engine to the transmission
by the torque converter is directly related to engine rpm.
Torque Converter
Operational phases
• 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.
Failure Problems
1. Overheating :-Continuous high levels of slippage resulting
in damage to the seals that retain fluid inside the
converter.
2. Stator clutch breakage:-A very abrupt application of
power can cause shock loading of the stator clutch,
resulting in breakage.
3. 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.
