Torque converter transmission system
A torque converter is a type of fluid coupling used in automatic transmissions to transfer power from the engine to the transmission. It allows the engine to run somewhat independently of the transmission, enabling smooth power transmission even when the vehicle is at a standstill.
The main components of a torque converter are:
1. Pump: Connected to the engine, it pushes transmission fluid toward the turbine.
2. Turbine: Connected to the transmission input shaft, it spins as the fluid from the pump hits it, transmitting power to the wheels.
3. Stator: Positioned between the pump and turbine, it redirects fluid coming from the turbine back into the pump to increase efficiency.
4. Transmission Fluid: Acts as the medium that transfers power from the engine to the transmission through the fluid coupling.
The torque converter also has a lock-up clutch that can mechanically link the engine and transmission directly, improving fuel efficiency by reducing slip at higher speeds.
It effectively replaces a manual transmission’s clutch system, allowing for smooth acceleration and deceleration without disengaging the engine.
