What is a Hydraulic Coupling?
1 Answers
Hydraulic coupling is used in automatic or semi-automatic transmissions, similar to the torque converter in AT transmissions. The medium inside a hydraulic coupling is oil, and this device connects two shafts together. AT transmissions are equipped with torque converters, which consist of an impeller, turbine, and guide wheel, and are installed between the engine and the transmission. Also known as a fluid coupling, a hydraulic coupling is a type of hydrodynamic drive that connects a power source to a working machine, transmitting torque through changes in the angular momentum of the fluid. It is a non-rigid coupling that uses liquid as the working medium.
