What Is a Torque Converter and How Does It Work?
A torque converter is a key part of automatic transmissions that helps transfer power smoothly from the engine to the wheels. It works using hydraulic principles to do this.
Inside, a turbine connects to the engine, while a stator and impeller are linked to the transmission. When the engine runs, the impeller pumps fluid, creating hydraulic pressure that spins the turbine.
This hydraulic fluid acts as both a lubricant and a power transfer medium, allowing the engine’s rotational force to be transmitted without a direct mechanical link. The stator redirects fluid flow to improve efficiency.
This setup helps the vehicle accelerate smoothly and decelerate seamlessly. It also amplifies torque, especially at low speeds, giving you a comfortable driving experience.
In essence, the torque converter acts like a hydraulic coupling, letting your vehicle accelerate smoothly without needing to engage a manual clutch.
