The stator is the barrier that directs the fluid back into the turbine instead of the pump, thereby increasing the efficiency of the system. The impeller or centrifugal pump effectively hurls the transmission fluid into the ribs of the turbine, which in turn rotates or transmits the torque to the transmission. The torque converter housing is connected to the flywheel and rotates at the same speed as the crankshaft in the turbine housing. In this way, the torque that is transmitted to the transmission via the input shafts can be measured A pump helps achieve torque control that works by circulating fluid around the torque converter, which is determined by the rotation of the crankshaft.Ī turbine is located in the housing and rotates when the pumped fluid comes into contact with the turbine blades. It’s a bit difficult to understand how fluid can provide the power to move something as essential as a vehicle. This is a feature beyond that of the simple fluid coupling, which can match rotational speed but does not multiply torque, thus reduces power. The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear. ![]() ![]() The equivalent location in a manual transmission would be the mechanical clutch. ![]() It is usually located between the engine’s flexplate and the transmission. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. A torque converter is a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load.
