A torque converter is a type of fluid coupling which transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load.In a vehicle with an automatic transmission, the torque converter connects the power source to the load.It is usually located between the engine's flexplate and the transmission. The equivalent location in a manual transmission would be. The automatic mechanical clutch enabled the taking off function, whereas the hydrodynamic torque converter enabled taking off in any gear, it dampened the engine vibrations, and it provided torque multiplication, functioning as some sort of reduction gearbox, so the actual mechanical gearbox only needed three forward gears (maybe you have wondered why traditional automatic transmissions with hydrodynamic torque converters usually have less gears than manual gearboxes. Converter Hydrodynamic torque converters have at least three vane wheels (main parts) that redirect the flow: the pump, turbine and reaction member, also called a guide wheel.

Blade leaning angle represents the angular position of a blade chord with respect to its radial reference line, and it is an important blade variable regarding both hydrodynamic performance and manufacturability of a torque converter transmissions, however, the torque converter (TC) in existing propelling transmissions is a low-efficiency component and leads to excessive energy consumption. Accordingly, this paper replaces the TC with a hydrodynamic mechanical power split transmission (HMPST) for improving the fuel economy of wheel loader A torque converter is a complex hydrodynamic turbo-machine; see figure 1 [9].
