3. Torque Converter

4. functions
 Transfer torque from the engine to
transmission input shaft
 Drives the front pump of the transmission
 To Multiply Engine Torque

5. anatomy of a torque converter

6. Principles of Operation
 Torque Converter is a
Fluid Coupling
 No direct Mechanical
Link
Impeller
Turbine

7. FLUID COUPLING PROBLEM
Click to play

8. SOLUTION
Introduce a STATOR

9. Phases of operation
Phase I - Torque
Multiplication Phase:
 Low Impeller Speed
 Stator is locked into
place by its one-way
clutch
 Vortex fluid flow within
the converter
Phase II - Coupling Phase:
No torque multiplication
Stator is freewheeling
Rotary flow within the
converter

10. Applications
Automatic Transmission Systems in
automobiles
Industrial Power Transmission
Drag Racing Cars(eg. Dodge Charger)

11. limitations
• Cannot be applied to Manual Transmission
• Expensive Assembly
