How Does Torque Converters Work?

You may be asking what is a torque converter and how does it work? Torque Converters are devices used in automatic transmissions that allow cars to keep running as they come to a complete stop. Instead of a clutch that is used to change gears in a manual transmission, automatic transmissions use a torque converter instead. In an automatic transmission car, the power source is connected to the load by the torque converter. The torque converter is responsible for transmitting the torque from the engine to a rotating driven load. Torque converters may not look like much but inside this component a lot of things are happening. If you have an automatic transmission in

your vehicle, this device is used daily.

How Does Torque Converters Work?

Torque Converters allows the engine in an automatic transmission to turn independently from the transmission as a fluid coupling system that takes the place of the clutch that a manual transmission requires. Torque control is achieved by a pump that sends fluid

around the torque converter and is determined by the crankshaft and its rotation. Torque converters house a turbine that pumps fluids as it rotates to turbine vanes which determines the amount of torque that gets to the transmission.

What’s Inside a Torque Converter?

There are four components inside the torque converter. Impeller, turbine, transmission fluid and stator.

1. Impeller

Impeller is a type of centrifugal pump. Fluid is flung as it spins.

2. Turbine

The fluid enters the blades of the turbine causing the transmission to spin.

 3. Transmission Fluid

This is the type of fluid inside the torque converter which helps transfer power generated from the engine to the transmission.

4. Stator

The stator is in the center of the torque converter. The stator has aggressive blades that help redirect the fluid before it hits the blades.
