Abstract: A magnetorheological (MR) fluid coupling for vectoring torque with respect to a shaft capable of rotary motion is disclosed. The coupling includes a stator, a rotor having a rotational degree of freedom with respect to the stator and configured for physical communication with the shaft, and a magnetic field generator. The stator and rotor define an annular space therebetween and are coupled via a MR fluid disposed within the annular space. The magnetic field generator is in field communication with the MR fluid and is disposed to produce a substantially radially directed magnetic field across the annular space. The rotor is rotationally responsive to the application of a magnetic field at the MR fluid.

Abstract: A power steering system for a vehicle includes a hydraulic pump interconnected with a power steering gear and a fluid coupling that operatively connects a drive shaft of an engine of the vehicle with the hydraulic pump. The power steering system also includes an electronic controller operable to provide a variable control signal based on received input to vary torque transmitted via the fluid coupling. The fluid coupling includes a coil operatively connected with the electronic controller and a magnetically permeable core disposed about the coil.
