The magnetorheological fluid (MR fluid), when exposed to a magnetic field, changes its viscosity to provide for increased shear stress resistance of the magnetorheological fluid (MR fluid). This increase in viscosity provides for the motion transmission between each of the conical shaped hollow head

The magnetorheological fluid (MR fluid), when exposed to a magnetic field, changes its viscosity to provide for increased shear stress resistance of the magnetorheological fluid (MR fluid). This increase in viscosity provides for the motion transmission between each of the conical shaped hollow heads and consequently to each of the input shaft and the output shaft in a rate, or ratio, proportional to the magnetic field generated by the electric coil(s). The shape of the electric coil(s) could be of a multitude of possible designs to produce a magnetic field having desired characteristics. Control of the electric coil(s) is provided by an electronic controller which interfaces with a multitude of sensors which provide sensorial information from various operation monitoring systems.
