1.Power Transfer:
Acts as a fluid coupling to transmit rotational power from the engine’s crankshaft to the transmission’s input shaft. It uses a pump (connected to the engine) and a turbine (connected to the transmission) to circulate hydraulic fluid, transferring energy through fluid motion.
2.Torque Amplification:
Contains a stator, which redirects fluid flow from the turbine back to the pump, creating a hydrodynamic effect that multiplies torque. This is most effective at low speeds, aiding in vehicle launch and heavy-load situations.
3.Damping and Vibration Reduction:
Absorbs engine vibrations and sudden torque fluctuations, preventing them from transferring to the transmission and driveline. This reduces noise and stress on mechanical components, improving ride quality.
4.Overrunning Clutch Function:
Many modern torque converters include a lockup clutch that engages at higher speeds (e.g., highway cruising). This clutch mechanically locks the pump and turbine together, eliminating fluid slippage, improving fuel efficiency, and reducing heat generation.
5.Fluid Circulation and Cooling:
Facilitates the flow of transmission fluid, which helps cool the transmission system by dissipating heat generated during operation. This cooling function is critical for maintaining optimal transmission performance and preventing overheating.
1.Smooth Power Transmission:
Eliminates the need for a manual clutch by using hydraulic fluid to transfer power between the engine and transmission. This hydraulic coupling ensures seamless acceleration and deceleration, reducing jolts during gear changes and enhancing overall driving comfort.
2.Torque Multiplication:
Delivers increased torque output during low-speed operations (e.g., starting from a stop or climbing hills). By leveraging fluid dynamics, it can multiply engine torque by a factor of 2–3, providing extra power when needed without straining the engine.
3.Reduced Mechanical Wear:
Since there is no direct metal-to-metal contact between moving parts (unlike a clutch), it minimizes friction and wear on transmission components. This extends the lifespan of the transmission system and reduces maintenance requirements.
4.Flexible Operation:
Allows the engine to continue running even when the vehicle is stationary (e.g., at a stoplight) without stalling, as the fluid coupling decouples the engine from the transmission. This feature is essential for automatic transmissions, simplifying driver operation.
5.Adaptability to Load Changes:
Automatically adjusts to varying driving conditions, such as sudden acceleration or heavy loads. It modulates fluid pressure and flow to match engine output with transmission demand, ensuring optimal performance across different scenarios.
