What is a Torque Converter and How Does it Work?

A torque converter is a type of fluid coupling that is used to transfer rotating power from a prime mover, such as an internal combustion engine, to a rotating driven load. It works by using the kinetic energy of the fluid within the converter to multiply torque and increase rotational speed.

So, what is a torque converter, and how does it work? The torque converter consists of three main components: an impeller, turbine, and stator.

  1. The impeller is connected to the engine’s crankshaft and spins at engine speed. As it spins, it draws in fluid from the transmission sump and accelerates it outward in all directions. This creates a low-pressure area at its center which causes more fluid to be drawn in from the sump. This process continues until all available fluid has been drawn into the impeller chamber.
  2. The accelerated fluid then passes through vanes on its way into the turbine chamber where it strikes against curved blades on the turbine wheel causing it to spin at a higher rate than that of the impeller wheel. The spinning turbine then drives an output shaft connected directly or indirectly (through gears) with other components such as wheels or pumps depending on what type of application is being used for this device.
  3. Finally, some of this high-velocity fluid passes through another set of vanes into a stator chamber where its velocity is reduced due to friction between itself and stationary blades inside this chamber before returning back into the transmission sump completing one cycle within the torque converter system.

In summary, when power from an internal combustion engine enters into the torque converter system via a crankshaft connection with an impeller wheel; kinetic energy stored within moving fluids accelerates the turbine wheel which further drives the output shaft connected with other components depending upon application requirement thus multiplying input torque while increasing rotational speed simultaneously.
