A torque converter is a type of fluid coupling used in automatic transmissions to transfer rotating power from the engine to the transmission. It allows the engine to continue running while the vehicle is stationary, and it smoothly transmits power to the wheels when the vehicle starts moving.
The torque converter serves several important functions:
Smooth Power Transfer: It enables a smooth connection between the engine and the transmission without the need for a manual clutch.
Torque Multiplication: During acceleration, it can multiply engine torque to help the vehicle move more easily from a standstill.
Shock Absorption: It cushions the drivetrain against sudden changes in engine speed, improving ride comfort and protecting mechanical components.
Automatic Operation: It supports the fully automatic behavior of modern automatic transmissions, allowing seamless gear changes without driver intervention.
Inside a torque converter, components like the impeller, turbine, stator, and transmission fluid work together to transmit and manage the flow of power efficiently.
