In a vehicle equipped with an automatic transmission, a torque converter connects a power source to a load. It is typically located between the flex plate of the engine and the gearbox. The primary characteristic of a torque converter is that it is capable of increasing torque when the output speed is low, thereby allowing fluid exiting the curved blades of the turbine to deflect from the stator when locked with the one-way clutch, thereby providing what corresponds to a reduction gear. This is a feature over simple fluid couplings that can match rotational speeds without increasing torque, thereby reducing power. Therefore, the power take-off interface of the torque converter is a very important structure, and it is very important how to withstand the large axial and radial loads and torques transmitted by the engine.
