Abstract
A hydrodynamic coupling apparatus () for transmitting torque between driving and driven elements includes an input shaft (), a first end () of which is rotatably supported in a case () and a second end () of which is connectable to a torque generator (). A hydrodynamic clutch () is connected to the first end () of the input shaft () and includes an impeller () and a turbine () enclosed in a clutch housing (). The impeller () is fixed to the first end () of the input shaft (), and the turbine () is rotatably supported adjacent the impeller (). Both the impeller () and the turbine () are immersed in magnetorheological fluid (). An electromagnetic field generator () is supported adjacent the clutch housing () and is operable to generate a magnetic field in the magnetorheological fluid (). The field generator is adjustable to adjust the density of the magnetic field flux and, consequently, the amount of torque transferred from the impeller () to the turbine ().
